OPINION
CHIEF JUSTICE TODD DECIDED: NOVEMBER 19, 2025
In this discretionary appeal, we must determine whether the unit of prosecution1
for the offense of Arson Endangering Persons (“AEP”)2 is each act of arson, or each
endangered person. For the reasons that follow, we hold that the unit of prosecution for
AEP is each act of arson, and, accordingly, we reverse the decision of the Superior Court
and remand the matter for resentencing consistent with this opinion.
I. Factual and Procedural History
1 A unit of prosecution is the actus reus, or conduct, that the General Assembly intends
to punish. Commonwealth v. Satterfield, 255 A.3d 438, 445 (Pa. 2021). In other words, “the unit of prosecution is the minimum conduct that must be proven to obtain a conviction for the statute in question.” Id. at 445-46. Critically, “[o]nly a single conviction and resulting punishment may be imposed for a single unit of prosecution.” Id. at 446. 2 18 Pa.C.S. § 3301(a)(1)(i). In February 2018, four police officers arrived at a rowhouse in Pittsburgh in an
effort to locate a missing person, John Van Dyke. The officers forcibly entered the home
and repeatedly announced their presence. Once inside, the officers heard Appellant,
Vincent Smith, who was on the second floor of the residence, declare “Steve’s not here.”
Commonwealth v. Smith, 298 A.3d 1140, 1141 (Pa. Super. 2023). After re-announcing
their presence and stating their purpose, the officers observed Appellant striking matches
and throwing them on the floor, instantly setting a fire that traveled down the stairs toward
the officers. The officers immediately exited the residence, and Appellant was rescued
by firemen and treated for smoke inhalation.
Subsequently, the bodies of Van Dyke and another man, Steven Pariser, were
recovered from the residence. Both men had trauma to the back of their heads, and it
was determined that Appellant had killed the men approximately five days earlier; thus,
their deaths were ruled as homicides. Appellant told detectives that the two victims had
attacked him, and he fought back by throwing them down a flight of stairs, after which he
covered them with blankets and bags. Appellant also stated that he wanted to kill himself,
and that he had attempted to do so by taking some pills and spreading lighter fluid around
the residence.
Appellant was charged with two counts of homicide, multiple counts of arson, and
related offenses. On April 5, 2021, Appellant entered open guilty pleas to two counts of
voluntary manslaughter3 for the deaths of Van Dyke and Pariser, and four counts of AEP,
one for each police officer present in the residence when he started the fire.
Subsequently, the trial court sentenced Appellant to 5 to 10 years imprisonment for each
voluntary manslaughter offense, and 4 to 8 years imprisonment for each AEP offense,
3 Id. § 2503.
[J-24-2025] - 2 with all sentences to run consecutively, for an aggregate sentence of 26 to 52 years
imprisonment.
Thereafter, in a post-sentence motion, Appellant challenged the voluntariness of
his plea, as well as the discretionary aspects of his sentence, and the trial court conducted
a hearing on August 23, 2021. During the hearing, the question arose as to whether an
individual may be sentenced on multiple counts of AEP under Section 3301 of the Crimes
Code based on a single arson that endangered more than one individual. The trial court
deferred ruling on Appellant’s post-sentence motion, and directed the parties to file
supplemental briefs addressing that issue. Pertinently, the AEP statute at issue provides,
in relevant part:
(a) Arson endangering persons.--
(1) A person commits a felony of the first degree if he intentionally starts a fire or causes an explosion, or if he aids, counsels, pays or agrees to pay another to cause a fire or explosion, whether on his own property or on that of another, and if:
(i) he thereby recklessly places another person in danger of death or bodily injury, including but not limited to a firefighter, police officer or other person actively engaged in fighting the fire; or 18 Pa.C.S. § 3301(a)(1)(i).
On September 20, 2021, after the parties filed their supplemental briefs, the trial
court conducted a second hearing, at which Appellant argued that, because he only
committed one arson, he could be sentenced on only one count of AEP. In support of his
position, Appellant relied on this Court’s decision in Satterfield, supra. In Satterfield, the
defendant was driving a tractor trailer on the interstate when he approached multiple
vehicles that were stopped at a construction zone. Without reducing his speed, he
crashed into several of the vehicles, resulting in the death of two people in one car, a third
in another car, and injuries to numerous others. Following the accident, Satterfield fled
[J-24-2025] - 3 the scene. Subsequently, he pled guilty to, inter alia, three counts of hit and run in
violation of 75 Pa.C.S. § 3742.4 Over his objection, the court sentenced him to three
consecutive terms of three to six years imprisonment. On appeal, Satterfield argued that
he should have been sentenced on a single count of violating Section 3742 because there
was a single accident after which he left the scene and, thus, he violated the statute only
once. The Superior Court rejected his argument, and affirmed his judgment of sentence.
On appeal, this Court determined that the unit of prosecution under Section 3742 is the
act of leaving the scene of an accident without first rendering aid and providing the
information required by 75 Pa.C.S. § 3744, regardless of the number of victims or the
severity of their injuries. Accordingly, we held that Satterfield violated Section 3742(a)
only once, and we vacated two of his three judgments of sentence.
Conversely, the Commonwealth, in the instant case, argued that the imposition of
separate sentences for each of the officers endangered by Appellant’s act of arson was
proper under this Court’s decision in Commonwealth v. Frisbie, 485 A.2d 1098 (Pa. 1984).
In Frisbie, the defendant was fleeing from police when he drove his car through a crowded
intersection, injuring nine pedestrians. Frisbie was convicted of one count of leaving the
4 At the time of the offense in Satterfield, Section 3742, titled “Hit and run,” provided, in
relevant part:
General rule.-- The driver of any vehicle involved in an accident resulting in injury or death of any person shall immediately stop the vehicle at the scene of the accident or as close thereto as possible but shall then forthwith return to and in every event shall remain at the scene of the accident until he has fulfilled the requirements of section 3744 (relating to duty to give information and render aid). Every stop shall be made without obstructing traffic more than is necessary. 75 Pa.C.S. § 3742(a). Effective July 3, 2023, Section 3742 was amended to add subsection (a.1), which pertains to “Highly automated vehicles.” Act of Nov. 3, 2022, P.L. 1946, No. 130, § 4.
[J-24-2025] - 4 scene, and nine counts of recklessly endangering another person (“REAP”) under 18
Pa.C.S. § 2705. That section provides, in relevant part, “[a] person commits a
misdemeanor of the second degree if he recklessly engages in conduct which places or
may place another person in danger of death or serious bodily injury.” Id. Frisbie was
sentenced to 10 one-year terms of probation, one for leaving the scene, and one for each
of the nine REAP offenses. On appeal, the Superior Court reversed Frisbie’s judgment
of sentence, holding that his single act of propelling his vehicle into a crowd supported
only one sentence. Upon further review, this Court reversed the Superior Court’s
decision. We held that the language of the statute – specifically, that a person commits
a second-degree misdemeanor “if he recklessly engages in conduct which places or may
place another person in danger of death or serious bodily injury” – suggested that the
legislature intended to allow separate punishments for each victim. Frisbie, 485 A.2d at
1100 (emphasis original). We further noted that the general purpose of the Crimes Code,
which includes imposing punishment that is proportionate to criminal liability and
differentiating among offenders based on the seriousness of the offenses, supported the
imposition of a separate sentence for each endangered individual.
In the case sub judice, the trial court ultimately found Frisbie controlling, and
concluded that, because the offense of AEP “requires proof of both an arson and that an
enumerated person be placed in danger of death or bodily injury from the arson,” the unit
of prosecution is each endangered person. Trial Court Opinion, 4/6/22, at 7 (emphasis
omitted). Accordingly, the trial court held that Appellant’s four separate sentences for
AEP were proper.
Appellant appealed his judgment of sentence to the Superior Court, claiming that
the trial court’s imposition of four separate sentences for separate AEP offenses
constituted an illegal sentence because Section 3301(a)(1)(i) provides for only a single
[J-24-2025] - 5 sentence, regardless of the number of victims endangered by the commission of a single
arson.5 Appellant argued, inter alia, that Section 3301(a)(1)(i) is ambiguous because
there are two possible interpretations of the statute. Specifically, Appellant asserted that
Section 3301(a)(1)(i) may be read as prosecuting each arson, or, alternatively, as
prosecuting “arsons as ersatz crimes against persons,” Smith, 398 A.3d at 1144. In
support of his claim that the intended unit of prosecution is each arson, rather than each
individual endangered by the commission of the arson, Appellant offered: (1) when there
are two reasonable interpretations of a statute’s unit of prosecution, a court should adopt
the more lenient one; (2) the titles of Section 3301 (“Arson and related offenses”) and
subsection 3301(a) (“Arson endangering persons”) suggest that the primary focus of the
offense is arson, not endangerment; and (3) although the AEP statute contains an
element of endangerment to another person in the singular, Section 1902 of the Statutory
Construction Act (“SCA”) provides that the “singular shall include the plural, and the plural,
the singular.” 1 Pa.C.S. § 1902.
Initially, a three-judge panel of the Superior Court reversed three of Appellant’s
four AEP convictions, vacated the corresponding judgments of sentence, and remanded
the case for resentencing. However, following reargument, an en banc panel of the
Superior Court, in an 8-1 decision, affirmed Appellant’s original convictions and
judgments of sentence.
In an opinion authored by then-Judge, now-Justice McCaffery, the court found the
language of Section 3301(a)(1)(i) to be unambiguous, and held that the intended unit of
5 When a defendant pleads guilty, he waives the right to challenge all but the legality of
his sentence and the validity of his plea. Commonwealth v. Montgomery, 401 A.2d 318, 319 (Pa. 1979). Thus, although Appellant pled guilty to four separate AEP offenses, his challenge to the legality of the sentences imposed for those offenses is non-waivable. Accordingly, his claims before us address his sentences for AEP, not the underlying convictions.
[J-24-2025] - 6 prosecution is the commission of an arson “coupled with” the reckless placement of
another person in danger of death or bodily injury. Smith, 298 A.3d at 1143 (emphasis
omitted). The court reasoned that the plain meaning of the word “and” at the end of
Section 3301(a)(1) “requires the Commonwealth to prove not only that a defendant
‘intentionally start[ed] a fire,’ but also that they ‘recklessly place[d] another person in
danger of death or bodily injury[.]’” Id. at 1147 (emphasis original).
Further, in considering whether Section 3301(a)(1)(i) “contemplates placing a
single person in danger, or more than one person,” the court found this Court’s decision
in Frisbie “instructive,” observing: The REAP statute at issue in [Frisbie] and the pertinent [AEP] subsection bear similarities. A person commits REAP when they “recklessly engage[ ] in conduct which places or may place another person in danger of death or serious bodily injury.” 18 Pa.C.S. § 2705 (emphasis added). The Frisbie Court emphasized the phrase, “another person” and . . . construed this language to mean “that § 2705 was written with regard to an individual person being placed in danger of death of serious bodily injury, and that a separate offense is committed for [each] individual person placed in such danger.” Frisbie, 485 A.2d at 1100. Similarly, the definition of [AEP] is the intentional starting of a fire “and” the “recklessly plac[ing] another person in danger of death or bodily injury[.]” See 18 Pa.C.S. § 3301(a)(1)(i) (emphasis added). Applying the rationale of Frisbie, we conclude the phrase, “another person,” “was written with regard to an individual person being placed in danger of death of serious bodily injury,” and thus separate offenses are committed for each person placed in such danger. Thus, separate sentences may be imposed.
Id. (emphasis original).
The court noted that Appellant neglected to address this Court’s holding in Frisbie
that, “[w]here the legislature has intended to preclude multiple punishments for multiple
injuries resulting from a single act, it has expressly done so.” Frisbie, 485 A.2d at 1100
(citing 18 Pa.C.S. § 2707 (it is a crime to throw a rock or any deadly or dangerous missile
[J-24-2025] - 7 into a vehicle “that is occupied by one or more persons”); 18 Pa.C.S. § 2710 (a person
commits ethnic intimidation if they commit an offense “with malicious intention toward the
race, color, religion or national origin of another individual or group of individuals”))
(emphasis omitted).
Thus, the Superior Court held that, under the plain language of Section
3301(a)(1)(i), the unit of prosecution for AEP is “the intentional starting of a fire which
recklessly places another person in danger of death or bodily injury,” and, therefore, that
“a defendant may be convicted of and sentenced separately on multiple counts if one act
of arson causes more than one person to be in danger of death or bodily injury.” Smith,
298 A.3d at 1148.
Judge Lazarus authored a dissenting opinion, in which she suggested that,
although the reckless endangerment of another individual is an element of AEP for
purposes of conviction, the inclusion of an “intentional” mens rea requirement for starting
a fire under Section 3301(a)(1), and the absence of any mens rea requirement for
reckless endangerment in subsection (i), demonstrates that the actus reus for AEP is the
setting of a fire, not the resulting endangerment. Id. at 1150 (Lazarus, J., dissenting).
Judge Lazarus further opined that the placement of the headings in Chapter 33 of the
Crimes Code supported Appellant’s construction of the statute, and she expressed her
disagreement with the majority’s conclusion that Frisbie is controlling, noting that the
REAP offense at issue in Frisbie criminalized unspecified conduct, whereas the AEP
statute “specifically applies to an actor who ‘intentionally starts a fire.’” Id. at 1152
(emphasis omitted). Concluding that the language of Section 3301(a)(1)(i) is ambiguous
because the unit of prosecution may reasonably be interpreted as either “the intentional
starting of a fire, or put another way, an arson,” id. at 1149, or the endangerment of
another person, Judge Lazarus indicated that she would apply the rule of lenity to strictly
[J-24-2025] - 8 construe the statute in favor of Appellant, and, as a result, vacate the judgments of
sentence on three of Appellant’s four convictions for AEP.
We granted Appellant’s petition for allowance of appeal to determine whether the
Superior Court erred in determining that the unit of prosecution for the offense of AEP is
each endangered person, as opposed to each arson. See Commonwealth v. Smith, 320
A.3d 82 (Pa. filed June 4, 2024) (order).
II. Arguments
Before this Court, Appellant initially contends that the text of Section 3301(a)(1)(i)
“plainly provides for a unit of prosecution of each arson, not each endangerment.”
Appellant’s Brief at 19 (emphasis omitted).6 In support of his position, Appellant offers
the following interpretation of the statute: A person commits [AEP] if he intentionally (the mens rea); starts a fire or causes an explosion, or . . . aids, counsels, pays or agrees to pay another to cause a fire or an explosion (the actus reus); and thereby recklessly places another person in danger of death or serious bodily injury (the result). Indeed, the language describes the conduct at issue as arson and then, using “thereby,” an adverb of causation, describes reckless placement of others in danger as the conduct’s result.
Id. at 20. In other words, Appellant maintains that it is the act of committing an arson,
which then results in endangerment of one or more individuals, that forms the basis of the
offense of AEP, irrespective of the number of individuals endangered by the act of
committing the arson.
Appellant further argues that “even if the language were ambiguous in isolation, its
plain meaning is further underscored by context.” Id. at 21. In this regard, he highlights
that Section 3301(a) is titled “Arson endangering persons” − plural. He also notes that
6 This argument is inconsistent with Appellant’s position before the trial court and Superior
Court, wherein he argued that Section 3301(a)(1)(i) was ambiguous.
[J-24-2025] - 9 Section 3301(a) is a subsection of Section 3301, which is titled “Arson and related
offenses”; that Section 3301 falls under Chapter 33 of the Crimes Code, which is titled
“Arson, Criminal Mischief, and Other Property Destruction”; and, finally, that Chapter 33
falls under Article C of the Crimes Code, which is titled “Offenses Against Property.” In
Appellant’s view, it is significant that the offense of AEP falls under Article C, pertaining
to property offenses, rather than under Article B of the Crimes Code, which concerns
“Offenses Involving Danger to the Person,” and, more specifically, that it does not fall
under Chapter 27, which is titled “Assault,” or under the REAP statute, 18 Pa.C.S. § 2705,
which provides that a person commits misdemeanor of the second degree if he engages
in conduct that recklessly places or may place another person in danger of death or
serious bodily injury.
Moreover, Appellant notes that Section 3301(a)(1)’s two subsections – subsection
(i), which requires the reckless endangerment of another person, and subsection (ii),
which requires the intent to destroy or damage an inhabited building – both focus on arson
as the actus reus.
Notwithstanding his argument that the language of Section 3301(a)(1)(i) is plain in
both isolation and context, and without acknowledging that consideration of the history of
a statute is appropriate only when the statute is ambiguous, Appellant argues that the
history of Section 3301 demonstrates that the intended unit of prosecution is each arson,
not each endangered person. Specifically, he offers that the adoption of Section 3301
was essentially a “housekeeping device,” Appellant’s Brief at 25, the intent of which was
to “bring order to a chaotic mélange of arson offenses with disparate penalties by creating
a sensible grading system based on the type of arson at issue,” as opposed to adopting
“a new crime against persons, id. at 29-30 (emphasis original). Appellant additionally
maintains that, if we find that Section 3301(a)(1)(i) is ambiguous, the rule of lenity requires
[J-24-2025] - 10 that we construe it strictly, and in his favor, and hold that the unit of prosecution is each
arson, not each endangered person.
Finally, Appellant asserts that, in concluding that the unit of prosecution for AEP is
each person endangered as a result of an arson, the Superior Court erred in relying on
this Court’s decision in Frisbie, which he alleges is “flawed and, in any event,
distinguishable.” Id. at 32 (emphasis omitted). In this respect, he reiterates the argument
he made to the Superior Court that, under the SCA, phrases such as “another person”
are deemed to include the plural “other persons,” id. at 32 (quoting 1 Pa.C.S. § 1902),
and he avers that Frisbie both neglected to conduct a meaningful analysis of legislative
intent, and failed to follow the rule of lenity. He contends that our holding in Frisbie should
be confined to its context – the offense of REAP − which is directed at “nonspecific
conduct which is conceptually defined by the subsequent language of endangerment.”
Id. at 35.
In response to Appellant’s arguments, the Commonwealth initially concedes that
Section 3301(a)(1)(i) is ambiguous, thus requiring this Court to engage in a statutory
construction analysis to determine the legislature’s intent. Commonwealth’s Brief at 12-
13. However, the Commonwealth maintains that such an analysis reveals that the
legislature intended that the unit of prosecution for AEP is the number of individuals
endangered as a result of the arson. The Commonwealth asserts that Appellant’s
contrary position “completely ignores the meaning of actus reus,” which the
Commonwealth notes is defined in Black’s Law Dictionary as “[t]he wrongful deed that
comprises the physical components of a crime and that generally must be coupled with
mens rea to establish criminal liability; a forbidden act.” Id. at 14 (emphasis and citation
omitted). Contrasting AEP with the offense of leaving the scene of an accident that was
at issue in Satterfield, the Commonwealth argues that AEP requires “something more”
[J-24-2025] - 11 than merely “starting a fire,” because starting a fire is not, in and of itself, a “wrongful
deed” or “guilty act,” as one might lawfully start a fire in a fireplace. Commonwealth’s
Brief at 15. In the Commonwealth’s view, because AEP requires the starting of a fire
which places another person in danger of death or bodily injury, the unit of prosecution is
not each arson, but, rather, each endangered person.
The Commonwealth acknowledges that the title of Section 3301(a) contains the
word “arson,” but argues that “[t]he headings prefixed to titles, parts, articles, chapters,
sections and other divisions of a statute shall not be considered to control,” and, even
when a statute is found to be ambiguous, “the title . . . may be considered only to resolve
the uncertainty.” Id. at 19 (citing Commonwealth v. Magwood, 469 A.2d 115, 119 (Pa.
1983)) (emphasis omitted). Then, in what appears to be its own about-face, the
Commonwealth asserts that, in the instant case, “there is no ambiguity.” Id.
The Commonwealth further argues that this Court’s decision in Frisbie supports its
position that the unit of prosecution for AEP is each endangered individual, not each
arson, highlighting our recognition that the purpose of the Crimes Code includes “ensuring
that punishment is proportionate with criminal liability,” and “differentiating among
offenders based on the seriousness of their offenses.” Id. at 20. The Commonwealth
submits that it is reasonable to presume that the legislature intended to punish someone
who sets fire to a structure that contains multiple occupants more severely than someone
who sets fire to an unoccupied or empty structure.
Finally, the Commonwealth observes that Section 3301 is written in the same
manner as the REAP statute in Frisbie, which criminalizes conduct that “places or may
place another person in danger of death or serious bodily injury.” Id. at 21 (emphasis
original). It notes, as did the Superior Court below, that, in Frisbie, we held that use of
the phrase “another person” suggested that a defendant may be convicted of separate
[J-24-2025] - 12 offenses for each individual placed in danger, and that, “[w]here the legislature has
intended to preclude multiple punishments for multiple injuries resulting from a single act,
it has expressly done so.” Frisbie, 485 A.2d at 1100 (citing 18 Pa.C.S. § 2707). In
response to Appellant’s claim that our decision in Frisbie was flawed, the Commonwealth
opines that Appellant merely “dislikes what Frisbie has to say.” Commonwealth’s Brief at
23.
III. Analysis
The question of the proper unit of prosecution for the offense of AEP under Section
3301(a)(1) is a question of statutory interpretation; accordingly, our standard of review is
de novo, and our scope of review is plenary. See Commonwealth v. (Shane) Smith, 221
A.3d 631, 636 (Pa. 2019).
In interpreting or construing a statute, our objective is to ascertain and effectuate
the intention of the General Assembly. 1 Pa.C.S. § 1921(a); Commonwealth v. Gamby,
283 A.3d 298, 306 (Pa. 2022). The General Assembly’s intent “is best expressed through
the plain language of the statute.” Gamby, 283 A.3d at 306. Thus, when the words of a
statute are clear and free from all ambiguity, the letter of the statute is not to be
disregarded under the pretext of pursuing its spirit. 1 Pa.C.S. § 1921(b).
However, if a statutory term, read in context within the overall statutory framework
in which it appears, has at least two reasonable interpretations, the term is ambiguous.
(Shane) Smith, 221 A.3d at 638. If the words of a statute are not explicit, or are
ambiguous, we may ascertain the intent of the General Assembly by considering the
following factors, as set forth in the SCA: (1) the occasion and necessity for the statute;
(2) the circumstances under which it was enacted; (3) the mischief to be remedied; (4)
the object to be attained; (5) the former law, if any, including other statutes upon the same
or similar subjects; (6) the consequences of a particular interpretation; (7) the
[J-24-2025] - 13 contemporaneous legislative history; and (8) legislative and administrative interpretations
of such statute. 1 Pa.C.S. § 1921(c). Further, under the rule of lenity, when the language
of a penal statute is ambiguous, it must be strictly construed in favor of the defendant. Id.
§ 1928(b)(1); (Shane) Smith, 221 A.3d at 639.
To reiterate, Section 3301 is titled “Arson and related offenses,” and subsection
(a) provides:
Arson endangering persons.--
(1) A person commits a felony of the first degree if he intentionally starts a fire or causes an explosion, or if he aids, counsels, pays or agrees to pay another to cause a fire or explosion, whether on his own property or on that of another, and if:
(i) he thereby recklessly places another person in danger of death or bodily injury, including but not limited to a firefighter, police officer or other person actively engaged in fighting the fire; or
(ii) he commits the act with the purpose of destroying or damaging an inhabited building or occupied structure of another.
(2) A person who commits arson endangering persons is guilty of murder of the second degree if the fire or explosion causes the death of any person, including but not limited to a firefighter, police officer or other person actively engaged in fighting the fire, and is guilty of murder of the first degree if the fire or explosion causes the death of any person and was set with the purpose of causing the death of another person. 18 Pa.C.S. § 3301(a).
As noted above, the actus reus, or unit of prosecution, is the conduct that the
General Assembly intends to punish. Stated another way, it is the minimum conduct that
must be proven in order to obtain a conviction under a particular statute. In determining
the correct unit of prosecution for a particular statute, “the inquiry should focus on whether
[J-24-2025] - 14 separate and distinct prohibited acts . . . have been committed.” Satterfield, 255 A.3d at
446 (citation omitted).
Based on the legislature’s use of the word “and” at the end of subsection (a)(1), it
is clear that a conviction for AEP requires both the intentional act of starting a fire or
causing an explosion, and one of two additional elements – the intentional act of starting
a fire or causing an explosion recklessly placed another person in danger of death or
bodily injury, see § 3301(a)(1)(i), or that the intentional act of starting a fire or causing an
explosion was done with the purpose of destroying or damaging an inhabited building or
occupied structure of another, see § 3301(a)(1)(ii).
It is less clear, however, whether the reckless placement of another person in
danger of death or bodily injury as described under subsection (i) is itself a component of
the prohibited act, as the Commonwealth argues, or simply a description of the result of
the prohibited conduct described in Section (a)(1), as Appellant maintains. Indeed, the
term “thereby,” which links the two, is defined as, inter alia, “a result of [an] action,”7 or an
adverb “used to introduce the result of the action or situation mentioned.”8
However, as discussed above, without proof of either subsection (i) or (ii), there
could be no conviction under Section 3301(a)(1). This suggests that placing another
person in danger of death or bodily injury is not merely a description of the result of the
prohibited act of starting a fire or causing an explosion, but, rather, an essential
component of the minimum conduct that must be proven to support a conviction – the
actus reus − under Section 3301(a)(1)(i).

https://www.oxfordlearnersdictionaries.com/us/definition/english/thereby?q_thereby
[J-24-2025] - 15 Hence, we consider the language of Section 3301(a)(1)(i) in context of the overall
statutory framework of Section 3301. As discussed above, Appellant submits, inter alia,
that the placement of Section 3301 under Chapter 33 – titled “Arson, Criminal Mischief,
and Other Property Destruction” – which is contained in Article C – titled “Offenses
Against Property” – instead of under Chapter 27 (“Assault”) of Article B (“Offenses
Involving Danger to the Person”), suggests that the focus of AEP is the arson, not the
person endangered, and so supports the conclusion that the actus reus, or unit of
prosecution, of AEP is each arson, not each endangered individual. Although the
headings prefixed to titles, parts, articles, chapters, sections and other divisions of a
statute are not controlling, they may be used to aid in the construction of a statute. 1
Pa.C.S. § 1924; Mezzacappa v. Northampton County, 334 A.3d 268, 283 (Pa. 2025)
(observing that, when first enacted, the title describing the Criminal History Record
Information Act, 18 Pa.C.S. §§ 9101-9193, revealed that a primary purpose of the act was
protecting an individual’s right to privacy). The placement of Section 3301 under Article
C of the Crimes Code pertaining to property offenses, rather than Article B regarding
offenses to the person, supports Appellant’s position that the actus reus the legislature
seeks to punish is, in fact, the commission of an arson.
Additionally, while this Court in Frisbie determined that the unit of prosecution for
the offense of REAP is each endangered individual, as Judge Lazarus observed below,
the REAP statute is codified under Article B of the Crimes Code, which is titled “Offenses
Involving Danger to the Person,” and the REAP statute criminalizes conduct against an
individual. Thus, our interpretation of the REAP statute in Frisbie does not, in our view,
control our interpretation of Section 3301(a)(1)(i) in the instant case.
However, the Crimes Code provides that it is designed to, inter alia, authorize
punishment that is proportionate with criminal liability, and to differentiate between
[J-24-2025] - 16 offenders based on the seriousness of their offenses. See 18 Pa.C.S. § 104(3) (one
general purpose of the Crimes Code is to “safeguard offenders against excessive,
disproportionate or arbitrary punishment”); id. § 104(5) (a general purpose of the Crimes
Code is to “differentiate on reasonable grounds between serious and minor offenses, and
to differentiate among offenders with a view to a just individualization in their treatment”).
In light of these stated purposes, it is reasonable to conclude that the legislature would
intend to punish more severely an individual that sets fire to a building containing multiple
occupants than an individual who sets fire to a structure containing a single occupant.
Moreover, as the Commonwealth points out, when the legislature has intended to
prohibit multiple punishments for multiple injuries resulting from a single act, it has done
so expressly. See id. § 2707 (it is a crime to throw a rock or any deadly or dangerous
missile into a vehicle that is occupied by “one or more persons”); id. § 2710 (a person
commits ethnic intimidation if they commit an offense with malicious intention toward the
race, color, religion or national origin of “another individual or group of individuals”).
Based on the foregoing, we find that there is support for both Appellant’s
interpretation that the unit of prosecution of AEP under Section 3301(a)(1)(i) is each
arson, and the Commonwealth’s interpretation that the unit of prosecution for the offense
is each endangered individual. Accordingly, because Section 3301(a)(1)(i) is capable of
multiple reasonable interpretations, we conclude that it is ambiguous. Thus, we turn to
consideration of the aforementioned factors set forth in Section 1921(c) of the SCA.
Upon review of those factors, we find that four in particular − the occasion and
necessity for the statute, the circumstances under which it was enacted, the mischief to
be remedied, and the object to be attained – support a conclusion that the unit of
prosecution for the offense of AEP under Section 3301(a)(1)(i) is each arson.
[J-24-2025] - 17 As Sheldon S. Toll noted in his discussion about the creation of the new Crimes
Code in Pennsylvania,
[b]ecause of the patchwork accretion of Pennsylvania penal statutes originating over 150 years ago, a systematic grading or rationale of sentencing did not exist. Consequently, punishment frequently was highly disproportionate to the degree of culpability of the offender and the danger of his criminal act to the community when compared to similar criminal acts. . . . The new Code systemizes the classification of all crimes into grades and degrees. Sheldon S. Toll, Criminal Law Reform in Pennsylvania: The New Crimes Code, 78 Dick.
L. Rev. 1, 3 (1973).
Addressing the specific treatment of arson-related crimes under the new Crimes
Code, Toll further observed:
Remembering that many of Pennsylvania statutes were originally formulated when the state was primarily rural, it was not surprising to find inordinately severe penalties for burning those objects most important to the farming community, and inadequately lax penalties for putting fire to some objects generally associated with our modern urban way of life. As a result, Pennsylvania had statutory proscriptions against burning a “. . . barn, stable or other outhouse” punishable by a maximum of twenty years imprisonment. Burning hay, wheat, corn, grain, vegetables, or any pile of coal, wood, fuel, planks, boards, etc., with a value of over $25 subjected the offender to a maximum of two years imprisonment. In contrast to these provisions were a ten-year maximum penalty for burning down a heavily populated school or theater, and a meager two-year maximum penalty for setting aflame a teeming tourist cruiser.
In the new Code, the harsher sentences for the unlawful burning of those structures deemed of first importance to a rural economy are gone. The Code encompasses all phases of the offense of arson by distinguishing between arson endangering life and arson endangering property only, classifying the former as a felony of the first degree and the latter merely as a felony of the second degree.
[J-24-2025] - 18 Id. at 7-8.
Thus, the Crimes Code, as a whole, was enacted to classify all crimes into grades
and degrees. Moreover, Section 3301, in particular, differentiates between arson
endangering persons and property − Section 3301(a) − and arson endangering only
property – Section 3301(c) – and allows for a harsher sentence for the former by
designating the offense of AEP as a felony of the first degree. There is nothing, however,
to suggest that the underlying intent of Section 3301(a) was to allow for separate
convictions and sentences for each endangered individual.9
Most critically, as noted above, because Section 3301 is a penal statute, under the
rule of lenity, it must be strictly construed in favor of Appellant. See (Shane) Smith, 221
A.3d at 639. As the United States Supreme Court explained in Dunn v. United States,
442 U.S. 100 (1979), the application of the rule of lenity is “not merely a convenient maxim
of statutory construction,” but, rather, “is rooted in fundamental principles of due process
which mandate that no individual be forced to speculate, at peril of indictment, whether
his conduct is prohibited.” Id. at 112. Thus, the ambiguity we have discussed above
should be resolved in Appellant’s favor.
9 We do not discount the Commonwealth’s position that it is reasonable to punish an
individual who commits a criminal act, including arson, that endangers many people more severely than an individual who commits a criminal act that endangers one person. However, where the endangerment of multiple individuals results from the commission of an arson, a defendant could be charged with a single AEP offense under Section 3301(a)(1)(i), and charged with multiple counts of REAP under 18 Pa.C.S. § 2705. See, e.g., Commonwealth v. Glass, 50 A.3d. 720 (Pa. Super. 2012) (defendant who set fire to his home in which his wife and two children were present, and subsequently was convicted of one count of AEP and three counts of REAP, was properly sentenced on AEP offense, and two counts of REAP, as one of the REAP convictions merged with the AEP conviction for sentencing purposes). While a REAP conviction requires the Commonwealth to prove that the victims were placed in danger of death or serious bodily injury (whereas AEP requires a showing of only bodily injury), doing so in the factual context of an arson ought to be undemanding.
[J-24-2025] - 19 For all these reasons, we hold that the unit of prosecution for the offense of AEP
is each arson, not each person endangered by the arson. Accordingly, we reverse the
decision of the Superior Court, and, because our decision may upset the trial court’s
overall sentencing scheme, we vacate his judgment of sentence and remand the matter
to the Superior Court for remand to the trial court for resentencing consistent with this
opinion.10
Order Reversed. Case remanded. Jurisdiction relinquished.
Justices Donohue, Dougherty and Wecht join the opinion.
Justice Mundy files a dissenting opinion in which Justice Brobson joins.
Justice McCaffery did not participate in the consideration or decision of this matter.
10 Notably, although Appellant requests that we vacate three of his four judgments of
sentence for AEP, he does not ask this Court to reverse any of his convictions for AEP. See Appellant’s Brief at 36 (“[I]f this Honorable Court agrees that the offense’s unit of prosecution is each arson, rather than each endangerment, it should vacate three of his four sentence[s] and remand for resentencing.”); id. at 37 (“[Appellant] respectfully requests that [this Court] enter an order reversing the en banc panel’s decision, vacating three of his four sentences for [AEP].”). Although we recognized in Satterfield that “[o]nly a single conviction and resulting punishment may be imposed for a single unit of prosecution,” 255 A.3d at 446, we emphasized that the validity of the charging documents and Satterfield’s guilty plea were not before us, and that we were “concerned only with the legality of the sentences imposed,” id. at 445 n.12. As Appellant likewise challenges only the legality of his sentence, consistent with our approach in Satterfield, we do not address the validity of Appellant’s convictions for AEP.
