COMMONWEALTH OF PENNSYLVANIA : IN THE SUPERIOR COURT OF : PENNSYLVANIA : v. : : : SYLVESTER RICHARD GREENE : : Appellant : No. 410 MDA 2024
Appeal from the Judgment of Sentence Entered March 17, 2023 In the Court of Common Pleas of Lycoming County Criminal Division at No(s): CP-41-CR-0001189-2021
BEFORE: OLSON, J., KUNSELMAN, J., and NICHOLS, J.
OPINION BY KUNSELMAN, J.: FILED: JUNE 18, 2025
Sylvester Richard Greene appeals from the judgment of sentence
entered following his conviction for driving under the influence (DUI) of a
controlled substance, possession of a controlled substance, and use or
possession of drug paraphernalia.1 On appeal, Greene challenges the
sufficiency of the evidence and evidentiary rulings made by the trial court. We
affirm.
The trial court set forth the following factual and procedural history:
This case arises from a traffic stop of a vehicle driven by [Greene] by officers of the Williamsport Bureau of Police at approximately 8:32 p.m. on April 8, 2021, in the 1100 block of High Street, within the City of Williamsport, Lycoming County, Pennsylvania. . . .
[Greene] waived his right to a jury trial by written waiver and proceeded to [a] bench trial on January 12, 2023. After trial, the ____________________________________________
1 75 Pa.C.S. § 3802(d)(2) (first offense); 35 P.S. §§ 780-113(a)(16) and
(32), respectively. The trial court acquitted Greene of speeding. See 75 Pa.C.S. § 3362(a)(1). J-S33040-24
[trial] court issued an order dated that same day and filed of record January 23, 2023: (1) finding [Greene] guilty of Count 1, [DUI] of a controlled substance (PCP), guilty of Count 2, possession of a controlled substance (PCP), and guilty of Count 3, possession of drug paraphernalia; (2) finding [Greene] not guilty of Count 4, speeding; and (3) scheduling sentencing for March 17, 2023.
Following sentencing, the [trial] court entered an order dated March 17, 2023 and filed of record March 21, 2023 sentencing [Greene]: (a) to pay the costs of prosecution; (b) to pay a fine of $2,000.00; (c) to incarceration in the Lycoming County Prison for a period of three (3) to six (6) months as to Count 1; (d) to a consecutive period of incarceration in the Lycoming County Prison of eight and one-half (8½) to seventeen (17) months as to Count 2; (e) to a consecutive period of probation of one (1) year as to Count 3; (f) to pay an Act 198 fee of $100.00; and (g) to complete fifty (50) hours of community service.
[Greene] appealed to the Superior Court on March 31, 2023, but the Superior Court dismissed the appeal by order of July 11, 2023 for failure to file a brief. [See Commonwealth v. Greene, 462 MDA 2023 (per curiam order).] [Following a Post Conviction Relief Act (“PCRA”) petition,] the [PCRA] court entered an order reinstating [Greene’s] direct appeal rights [nunc pro tunc] and directing him to file a notice of appeal within thirty (30) days. [Greene], accordingly, filed the within appeal on March 22, 2024.
Trial Ct. Op., 4/23/24, at 1-3 (footnotes omitted and formatting altered).
Both Greene and the trial court complied with the mandates of
Pennsylvania Appellate Rule 1925.
Greene raises the following three issues for our review:
1. The trial court wrongfully convicted [] Greene by permitting Officer Andrew Stevens of the Williamsport Police Department to render an opinion that [] Greene was under the influence of phenyl cyclohexyl piperidine (PCP) when Officer Stevens was not admitted as an expert witness under Pennsylvania Rule of Evidence 702.
-2- J-S33040-24
2. The trial court wrongfully convicted [] Greene by finding sufficient evidence to support the offense of [DUI] of a controlled substance when the Commonwealth failed to offer expert testimony to establish that [] Greene was unable to safely operate his vehicle and that [] Greene’s inability to do so was caused by the ingestion of a controlled substance.
3. The trial court wrongfully convicted [] Greene by finding sufficient evidence to support a conviction for the offense of [DUI] of a controlled substance when the Commonwealth’s witness testified that, in part, his basis for concluding [] Greene was under the influence of PCP was his conclusion that [] Greene’s vehicle was exceeding the speed limit and the Commonwealth failed to provide proof that the utilized speedometer was certified invalidating speeding as an admissible basis for concluding that [] Greene was under the influence to a degree that rendered him incapable of safe driving beyond a reasonable doubt.
Appellant’s Brief at 4 (some formatting altered).2
In his first issue, Greene challenges the admission of Officer Stevens’
opinion that he was under the influence of PCP as an expert opinion under
Pennsylvania Rule of Evidence 702,3 because Officer Stevens was not offered
____________________________________________
2 The Commonwealth did not file a brief in this matter.
3 Rule 702 provides:
A witness who is qualified as an expert by knowledge, skill, experience, training, or education may testify in the form of an opinion or otherwise if: (a) the expert's scientific, technical, or other specialized knowledge is beyond that possessed by the average layperson; (b) the expert's scientific, technical, or other specialized knowledge will help the trier of fact to understand the evidence or to determine a fact in issue; and (c) the expert's methodology is generally accepted in the relevant field.
(Footnote Continued Next Page)
-3- J-S33040-24
as an expert witness.4 This issue challenges the admissibility of evidence.
Preliminarily, we note that the admission of evidence is solely within the
discretion of the trial court, and a trial court’s evidentiary rulings will be
reversed on appeal only upon an abuse of that discretion. Commonwealth v.
Walters, 323 A.3d 151, 157 (Pa. 2024). An abuse of discretion is not simply
an error of judgment, but is an overriding misapplication of the law, or the
exercise of judgment that is manifestly unreasonable, or the result of bias,
prejudice, ill-will, or partiality. Id.
Pennsylvania courts have relied on federal case law to distinguish
between an officer’s lay and expert testimony as follows:
We have explained that a law enforcement officer’s testimony is lay opinion if it is limited to what he observed . . . or to other facts derived exclusively from a particular investigation. . . . On the other hand, an officer testifies as an expert when he brings the wealth of his experience as an officer to bear on those observations
Pa.R.E. 702. By contrast, Rule 701 provides that a witness may offer lay testimony rationally based on the witness’s perception that is helpful to determining a fact in issue, and that is not based on scientific, technical, or other specialized knowledge. See Pa.R.E. 701.
4 Greene’s counsel interjected when Officer Stevens began his testimony to inquire about whether the Commonwealth was offering Officer Stevens as a Drug Recognition Expert, because he believed a Frye hearing would have been necessary. N.T., Trial, 1/12/23, at 10-11. The court indicated that expert testimony was not necessary to establish DUI, and that the officer’s training went only to the weight of the opinion of whether Greene was under the influence of drugs, not its admissibility. Id. at 11. After this discussion, the Commonwealth never offered Officer Stevens as an expert witness, and it was clear that Greene’s counsel objected to the testimony being offered as expert opinion. Thus, Greene preserved this issue for our review.
-4- J-S33040-24
and makes connections for the [fact finder] based on that specialized knowledge.
Commonwealth v. Jones, 240 A.3d 881, 890 (Pa. 2020) (quoting
Commonwealth v. Huggins, 68 A.3d 962, 969 (Pa. Super. 2013) (quoting
United States v. Christian, 673 F.3d 702, 709 (7th Cir. 2012))) (some
punctuation modified).
Greene relies on the Supreme Court’s decision in Jones to argue that
the officer’s testimony that he was under the influence of PCP required
specialized knowledge and was inadmissible as lay opinion. Greene’s Brief at
11-13. In Jones, Detective Holzwarth opined that child sexual assault victims
are often unable to recall specific details and dates of sexual assaults. The
detective was not offered as an expert witness under Rule of Evidence 702.
Jones claimed this opinion was expert testimony and not admissible under Rule
701, because it was not within the scope of knowledge possessed by the
average layperson. Our Supreme Court agreed.
Detective Holzwarth was asked to provide insights gained through specialized occupational training and experience not within the average layperson’s knowledge base as required by the plain language of Rule 702(a). [He] called upon the wealth of his knowledge and training as a detective with extensive experience investigating sexual assaults and made connections for the jury based on that specialized knowledge. While some laypersons may be aware of common behaviors and responses to sexual abuse, it would be a generalization to assume the average juror is privy to the complex psychological dynamics of sexual abuse.
Jones, 240 A.3d at 891.
-5- J-S33040-24
The Jones court concluded that the detective’s opinion fell within the
realm of expert testimony and was inadmissible under Rule 701.5
In the context of DUI, this Court has similarly held that a police officer
could not offer lay opinion testimony regarding the effects of marijuana use on
the body. Commonwealth v. Gause, 164 A.3d 532 (Pa. Super. 2017) (en
banc). In Gause, Officer Eiker opined that Gause was under the influence of
marijuana, due to eyelid and body tremors. An en banc panel of this Court
concluded that this opinion required specialized knowledge and was thus
inadmissible as lay opinion under Rule 701.6 We noted “[a]lthough Officer
Eiker could testify as to her observations of an apparent physical condition, a
qualified expert is required to provide the connection between the symptoms
observed and the drug allegedly influencing the defendant’s driving.” Id. at
539.
Here, Office r Stevens testified that Greene was under the influence of a
specific drug, namely PCP.7 This is akin to Officer Eiker’s testimony in Gause,
5 As discussed later, the Jones court also believed the error was not harmless
and ordered a new trial.
6 The Gause court did not determine whether the officer’s opinion would have
been admissible under Rule 702, because that issue was not before the court. Gause, 164 A.3d at 539, n.9. That issue is also not before this Court because Officer Stevens was not offered as an expert witness.
7 This case is distinguishable from Commonwealth v. Nestor, 314 A.3d 863
(Pa. Super. 2024), where the officer testified only that the defendant was under the influence of a controlled substance. The Nestor court observed, “Critically, (Footnote Continued Next Page)
-6- J-S33040-24
where Officer Eiker connected body and eyelid tremors to marijuana use.
Connecting a specific drug with a defendant's bodily reactions is generally
beyond the knowledge of an ordinary layman. In fact, here, Officer Stevens
prefaced his opinion by noting that he was a certified drug recognition expert
(DRE) and a certified DRE instructor. N.T., Trial, 1/12/23, at 10. He also noted
that he had specific training and experience with respect to detecting PCP. Id.
at 20. Undoubtedly, his testimony about the odor of PCP8 and the indicators
that Greene was under the influence of PCP, in particular Greene’s blank stare
and laughing when he was asked a question, involved specialized knowledge
beyond that of an ordinary layperson.
Indeed, the trial court acknowledged that Officer Stevens’ opinion was
beyond that of an ordinary layperson. See Trial Court Opinion, 4/23/24, at 14
(“Far from the ordinary lay witness, Officer Stevens is experienced in dealing
with individuals under the influence of controlled substance(s).”). Yet, the trial
court failed to appreciate that this rendered Officer Stevens’ opinion
unlike the officer in Gause, ‘Trooper Zimmerman did not voice an opinion as to which controlled substance he suspected [Nestor] had ingested. . . .’” Id. at 872 (record citation omitted) (emphasis added). Rather, Trooper Zimmerman opined that “Nestor was impaired by a stimulant.” Id. at 872-73.
8 While the odor of marijuana is familiar to the average layperson, the odor of
PCP is not.
-7- J-S33040-24
inadmissible under Rule 701,9 and it overlooked that Officer Stevens was never
offered as an expert witness under Rule 702. The trial court erred when it
impliedly overruled Greene’s objection, and it stated that the officer’s training
went only to the weight of his opinion of whether Greene was under the
influence of drugs, not its admissibility. N.T., Trial, 1/12/23, at 11. This was
a question of admissibility.
Because testimony that Greene was under the influence of the specific
drug PCP was beyond the knowledge of an average layperson, it was
improperly admitted as lay opinion under Rule 701. By misapplying the law,
the trial court abused its discretion, when it allowed Officer Stevens to give his
opinion that that Greene was under the influence of PCP.
9 The trial court states that the officer’s “perceptions at the scene were informed by his narcotics training, prior drug arrests and knowledge of the effects of [PCP].” Trial court opinion, 4/23/24 at 16. The trial court relied on this Court’s decision in Commonwealth v. Yedinak, 676 A.2d 1217 (Pa. Super. 1996). There, we determined for the first time that lay opinion testimony was admissible to prove drug-induced intoxication (as opposed to alcohol-induced intoxication). Id. at 1221. We found no basis upon which to distinguish opinion testimony of drug-induced intoxication from opinion testimony of alcohol-induced intoxication where the witness was personally familiar with the effects of narcotics. Id. We observed that “Officer Weiss based his opinion that appellant was under the influence of a controlled substance on specific and articulable observations of appellant’s physical appearance and behavior.” Id. As in Nestor, the officer’s lay opinion in Yedinak involved whether the appellant was under the influence of a controlled substance generally, and not whether the appellant was under the influence of a specific drug. The trial court also relied on Commonwealth v. Spence, 290 A.3d 301 (Pa. Super. 2023). That case involved a challenge to the sufficiency of the evidence, not the admissibility of lay opinion testimony.
-8- J-S33040-24
Although Greene is correct that the trial court erred by admitting Officer
Steven’s expert opinion testimony, we must also determine whether the error
was harmless. Once an appellate court determines a trial court improperly
admitted testimony, it must determine the appropriate remedy. An error may
be considered harmless “only if the appellate court is convinced beyond a
reasonable doubt that the error is harmless.” Jones, 240 A.3d at 891 (citation
omitted). An error cannot be considered harmless unless the court determines
that the error could not have contributed to the verdict. “Whenever there is a
reasonable probability that the error might have contributed to the conviction,
the error is not harmless.” Id. Our High Court has outlined three scenarios
under which an error may be deemed harmless, which have been summarized
in our case law as follows:
Harmless error exists if the state proves either: (1) the error did not prejudice the defendant or the prejudice was de minimis; or (2) the erroneously admitted evidence was merely cumulative of other untainted evidence which was substantially similar to the erroneously admitted evidence; or (3) the properly admitted and uncontradicted evidence of guilt was so overwhelming and the prejudicial effect of the error was so insignificant by comparison that the error could not have contributed to the verdict.
Id. at 892 (citation omitted).
The Jones Court found the detective’s testimony regarding the behavior
of children following sexual assaults was not harmless error. Id. That case
involved competing narratives about whether the assaults occurred, making
credibility a central issue. “The Commonwealth’s emphasis on Detective
Holzwarth’s training and experience prior to eliciting testimony concerning
-9- J-S33040-24
common victim behavior in response to sexual abuse likely signaled to the jury
that he was qualified to offer such a response.” Id. As a result, “the jury was
able to draw an inference that the victim’s behavior in this case was consistent
with similarly situated victims, without any of the heightened reliability
concerns that accompany expert testimony.” Id. Thus, the court could not
say for certain that the jury did not place undue weight on the detective’s
testimony. Because the error might have contributed to the verdict, Jones was
entitled to a new trial.
Similarly, in Gause, this Court determined that the admission of lay
opinion testimony regarding the marijuana impairment was not harmless error
in supporting a DUI conviction. There, “Officer Eiker’s testimony regarding
body and eye tremors was central to the Commonwealth’s case pertaining to
marijuana impairment, as it was the only factor she attributed to marijuana
impairment.” Gause, 164 A.3d at 540 (emphasis added). Without expert
testimony, we noted, “the jury was permitted to engage in speculation that the
observation of eye tremors indicates marijuana impairment, or at the least
ingestion.” Id.
Significantly, no other evidence indicated that Gause was under the
influence of a controlled substance. Gause was initially pulled over because
his taillights were not illuminated. Id. at 535. Nothing indicated that he drove
unsafely, or that he was otherwise impaired by a controlled substance.
Although Gause showed some impairment on the walk-and-turn test, he
showed no impairment on the Horizontal Gaze Nystagmus (HGN) test, and he
- 10 - J-S33040-24
did not show sufficient clues for DUI impairment on the one-leg stand test. Id.
There was no testimony that his results on the Romberg balance test indicated
impairment. Id. Additionally, Gause properly signaled and pulled over
immediately, and gave the officer his information without fumbling; there was
no odor of marijuana from the car or his person, no testimony that his eyes
were bloodshot, and no evidence of recent marijuana usage. Id. at 538-39.
As we observed, “there was a total lack of proof that Gause was under the
influence of a drug to a degree that his ability to safely drive was impaired.”
Id. at 540. Thus, we determined his conviction could not stand.
Here, by contrast, the Commonwealth offered a plethora of other
evidence that Greene was too impaired to drive. Greene initially was pulled
over for speeding, a factor indicating unsafe driving.10 Critically, Greene failed
several sobriety tests.11 For the walk-and-turn test, Greene displayed seven
of eight signs of impairment. N.T. at 24-25. For the one-leg stand test, Greene
displayed three of four signs of impairment. Id. at 25-26. Officer Stevens
also noticed that Greene was swaying during some of the field sobriety tests, ____________________________________________
10 Greene argues that because he was found not guilty of the speeding charge,
speeding cannot be considered as a sign of impairment. Greene’s Brief at 17- 18. We disagree. Although the Commonwealth could not prove speeding beyond a reasonable doubt, the officer’s observations of Greene’s driving are still relevant in determining whether Greene was too impaired to drive. Especially here, where the officer also noted that Greene “nearly caused a rear end collision” and had to “abruptly brake” to avoid hitting the car in front of him. See N.T. at 17-18.
11 The court did not consider the failed HGN test in rendering its decision. See discussion at N.T. at 24-25.
- 11 - J-S33040-24
which, while not a validated clue, was another “observation of impairment.”
Additionally, Greene asked the officer to repeat himself several times, gave
incomplete verbal responses, was confused, was unable to complete simple
tasks that the officer gave him, and had slurred speech. Id. at 26, 32. A
cigarette containing PCP was also discovered in Greene’s car. 12 Id. at 36. And
Officer Gino Caschera testified, without objection, that he smelled PCP coming
from Greene’s car and person. Id. at 61.
Based on this additional evidence, we conclude the “the erroneously
admitted evidence was merely cumulative of other untainted evidence which
was substantially similar to the erroneously admitted evidence.” Jones,
supra, at 182. Therefore, the admission of Officer Steven’s expert testimony
regarding the odor of PCP and signs that Greene was under the influence of
the specific drug PCP was harmless error.
In his next two issues, Greene challenges the sufficiency of the evidence
to convict him of DUI of a controlled substance under 75 Pa.C.S.A. §
3802(d)(2). We note that a challenge to the legal sufficiency of the
Commonwealth’s evidence “presents a question of law, for which our standard
of review is de novo, and our scope of review is plenary.” Commonwealth v.
Brashear, 2024 PA Super 317, 331 A.3d 669, 672 (Pa. Super. 2024),
reargument denied (Mar. 10, 2025). “This Court views the record in the light
12 By contrast, no physical evidence of recent marijuana use was discovered in
Gause.
- 12 - J-S33040-24
most favorable to the Commonwealth, giving the prosecution the benefit of all
reasonable inferences to be drawn from the evidence.” Id. “Evidence will be
deemed sufficient to support the verdict when it establishes each material
element of the crime charged and the commission thereof by the accused,
beyond a reasonable doubt.” Id.
The relevant DUI statute provides:
(d) Controlled substances—An individual may not drive, operate or be in actual physical control of the movement of a vehicle under any of the following circumstances:
***
(2) The individual is under the influence of a drug or combination of drugs to a degree which impairs the individual’s ability to safely drive, operate or be in actual physical control of the movement of the vehicle.
75 Pa.C.S.A. § 3802(d)(2).
We have emphasized that “Section 3802(d)(2) does not require that any
amount or specific quantity of the drug be proven in order to successfully
prosecute under that section.” Commonwealth v. Williamson, 962 A.2d
1200, 1204 (Pa. Super. 2008) (emphasis in original). Rather, the
Commonwealth must simply prove that, while driving or operating a vehicle,
the accused was under the influence of a drug to a degree that impaired his or
her ability to safely drive that vehicle. Id.
In his second issue, Greene maintains that the evidence was insufficient
because the Commonwealth failed to offer expert testimony to establish that
- 13 - J-S33040-24
Greene was unable to safely operate his vehicle and that Greene’s inability to
drive safely was caused by the ingestion of a controlled substance.
The Pennsylvania Supreme Court has held that, "expert testimony is not
mandatory in every prosecution to establish that a defendant's inability to drive
safely was caused by the ingestion of a controlled substance."
Commonwealth v. Griffith, 32 A.3d 1231 (Pa. 2011). “[T]he need for expert
testimony in subsection 3802(d)(2) prosecution must be evaluated on a case-
by-case basis, taking into account not just the specific drug at issue,
prescription or otherwise, but also the nature and overall strength of the
Commonwealth's evidence." Id. at 1239.
Greene argues that he was stopped “solely because he was ‘observed’ to
be exceeding the speed limit. (Transcript, 01/12/23, page 13). No other unsafe
driving was observed.” Appellant’s Brief at 15. Additionally, he claims that
the opinion regarding PCP use was inadmissible expert opinion, and with no
other expert, the evidence was insufficient.
The record belies this argument. As noted in the harmless error analysis
above, the Commonwealth offered substantial other evidence that Greene was
too impaired to drive due to the ingestion of PCP. Greene was not only
observed to be speeding, but the officer also noted that Greene “nearly caused
a rear end collision” and had to “abruptly brake” to avoid hitting the car in front
of him. See N.T. at 17-18. He performed poorly on the field sobriety tests.
Id. at 24-26. Additionally, Greene asked the officer to repeat himself several
- 14 - J-S33040-24
times, gave incomplete verbal responses, was confused, was unable to
complete simple tasks that the officer gave him, and had slurred speech. Id.
at 26, 32. A cigarette containing PCP was also discovered in Greene’s car. 13
Id. at 36. And Officer Gino Caschera testified, without objection, that he
smelled PCP coming from Greene’s car and person. Id. at 61.
Given the strength of this other evidence, the Commonwealth did not
need expert testimony; the other evidence of drug impairment was sufficient
to prove beyond a reasonable doubt that Greene was unable to safely operate
his vehicle. Thus, the evidence was sufficient to convict Greene of DUI under
section 3802(d)(2).
In his final issue, Greene similarly contends that the evidence was
insufficient to convict him of DUI of a controlled substance conviction because
he was acquitted of speeding and therefore speeding could not be used to
establish that he was too impaired to drive due to drug use. We acknowledge
that Greene was acquitted of the speeding offense.14 If speed alone was the
only evidence the Commonwealth relied on to support the charge of impaired
driving due to drugs, Greene’s argument might warrant relief.
13 By contrast, no physical evidence of recent marijuana use was discovered in
14 At trial, Greene argued the Commonwealth failed to provide proof that the
speedometer was certified.
- 15 - J-S33040-24
However, here Greene’s speed was merely a factor that gave the officers
reasonable suspicion to stop Greene to investigate the cause of his erratic
driving. Greene concedes that the stop was valid. Appellant’s Brief at 14. The
officers also observed, and offered dash cam video to support, that Greene had
to abruptly apply his brakes to avoid a rear end collision. Also, as discussed,
once officers pulled over Greene, there was other sufficient evidence to support
the DUI conviction: Greene’s behavior; the failed sobriety tests; the presence
of a cigarette with PCP; and the smell of PCP, as Officer Caschera testified to
without objection. The fact that Greene was acquitted of speeding does not
render this other evidence inadmissible or insufficient to satisfy the
Commonwealth’s burden of proof.
Moreover, in a bench trial, the trial court, acting as the factfinder, “is
presumed to know the law, ignore the prejudicial statements, and disregard
inadmissible evidence.” Commonwealth v. McFadden, 156 A.3d 299, 309
(Pa. Super. 2017) (citation omitted). Thus, Greene’s acquittal of the speeding
charge did not adversely affect the trial court’s decision to convict him of DUI.
His final issue warrants no relief.
Judgment of sentence affirmed.
