RILEY DYSON BIRO MEMORANDUM OPINION* BY v. Record No. 0011-24-1 JUDGE DANIEL E. ORTIZ APRIL 29, 2025 COMMONWEALTH OF VIRGINIA
FROM THE CIRCUIT COURT OF GLOUCESTER COUNTY Jeffrey W. Shaw, Judge
Charles E. Haden for appellant.
Rachel A. Glines, Assistant Attorney General (Jason S. Miyares, Attorney General, on brief), for appellee.
The circuit court convicted Riley Dyson Biro of misdemeanor obstruction of justice for
kicking a law enforcement officer. On appeal, Biro argues that the circuit court erred when it
denied his pretrial motion to dismiss because the Commonwealth did not preserve a video of the
assault. He claims it is clearly exculpatory and we must presume that the Commonwealth acted
in bad faith. We disagree. Viewing the evidence in the light most favorable to the
Commonwealth, we find that Biro offered little proof that the surveillance video had “apparent
exculpatory value” before it was destroyed or that the Commonwealth acted in bad faith. Biro
also challenges his conviction, claiming that the circuit court could not, on its own, amend the
original indictment of felony assault and battery of a law enforcement officer and that the
amendment changed the nature or character of the offense charged. Biro preserved neither
argument and thus we affirm the conviction.

We recite the facts in the light most favorable to the Commonwealth, the prevailing party
below. Camann v. Commonwealth, 79 Va. App. 427, 431 (2024) (en banc). “Doing so requires
that we ‘discard’ the defendant’s evidence when it conflicts with the Commonwealth’s evidence,
‘regard as true all the credible evidence favorable to the Commonwealth,’ and read ‘all fair
inferences’ in the Commonwealth’s favor.” Id. (quoting Commonwealth v. Cady, 300 Va. 325,
329 (2021)).
I. The Assault and Battery
On April 9, 2023, Investigator Matthews of the Gloucester County Sheriff’s Office
arrested Biro for written threats of death or bodily injury. While Matthews was interviewing
Biro at the jail, Biro became increasingly agitated and scratched at his handcuffed wrists. When
Biro calmed, Matthews and another deputy moved him to the main booking area so he could
appear by video before a magistrate. During the probable cause hearing, Biro again grew
agitated, picking at and biting his wrists. Biro stood and started yelling at Matthews, saying
“Fuck you,” “that he wanted to stick his penis into the ass of Deputy Franks’[s] son,” and that he
would “fuck [Matthews’s] daughter.” Believing it was “unsafe” to continue, Matthews ended
the video call with the magistrate.
Matthews, Deputy Collins, and one other deputy then tried to move Biro into the hallway
toward a restraint chair in the booking area, but they had to hold him against the wall until he
calmed down. Once he settled, they walked him down the hall. Two deputies were on each side
of Biro, and Matthews was either behind him or over his right shoulder. Biro was handcuffed,
and his legs were shackled. As they walked, Biro started thrashing, kicking back and forth, and
tensing his body. Biro was “repeating threats to Investigator Matthews,” said “Fuck you,” and
then kicked out, hitting Matthews’s shin. To avoid further confrontation, Matthews left Biro
-2- with the other deputies. Matthews later filed a criminal complaint in the Gloucester County
General District Court for assault and battery of a law enforcement officer.
II. Pretrial
A day later, the magistrate issued an arrest warrant for assault and battery of a law
enforcement officer. Shortly after, Biro’s counsel informally requested discovery from the
Commonwealth and followed up sometime later. According to the Commonwealth, it received
Matthews’s report on May 25, 2023. The report was redacted and given to Biro’s counsel on
June 9, 2023, along with a discovery flash drive. The flash drive had Matthews’s report, copies
of the warrants, and video files unrelated to Biro’s assault and battery charge. There was no
footage from the jail’s surveillance system.
On August 3, 2023, the general district court certified the charge to the grand jury, which
returned a true bill on September 5, 2023. On September 18, 2023, the Commonwealth emailed
Biro’s counsel that it learned that the jail automatically deletes surveillance footage after 30
days, meaning none of the April footage was preserved. Biro’s counsel requested a subpoena
duces tecum from the Gloucester Sheriff’s Office on November 16, 2023, looking for
“documents, manuals, or policies regarding the preservation of video recordings,” “[c]opies of
all videos” surrounding the April incident, and Matthews’s and other officers’ documents
“evidencing any request for preservation.” The sheriff’s office responded on December 5, 2023,
explaining that the jail only preserves videos for 30 days, that no footage from April was
available, and that the Department of Corrections does not require a preservation policy. Biro
then moved to dismiss the charge, alleging that Matthews and the Commonwealth intentionally
did not preserve exculpatory evidence. The circuit court denied the motion, explaining that it did
not “find there [was] any bad faith.”
-3- III. Trial
During the bench trial, Biro’s counsel moved to strike the Commonwealth’s evidence.
After argument, the circuit court found that there was a variance in the Commonwealth’s
evidence, so it amended the indictment to obstruction of justice under Code § 18.2-460(B). The
court then tried to arraign Biro on the new offense. Biro, speaking for himself, said “Your
Honor, I plead not guilty. I am not indicted for obstruction of justice and I believe the
obstruction of justice is not a lesser included offense to assault.” The court answered, “I’m not
saying it is. That’s why it’s been amended. . . . He pleads not guilty. . . . Any evidence for the
defendant?” After conferring with Biro, his counsel addressed the court: “Judge, maybe this is a
teachable moment. He’s charged with a felony assault and batter[y]. This is not a lesser
included charge. Is the [c]ourt bringing the charge?” The court responded, “No. Under
19.2-231, the [c]ourt is finding a variance between the allegations and the offered proof. The
[c]ourt is amending it to what it should be.” Counsel replied, “Okay. . . . I understand, Judge.
No evidence, Judge.” And counsel later said, “Judge, . . . I understand what the Commonwealth
is saying and I get what the [c]ourt has done here.” The court then found Biro guilty of
obstruction of justice and sentenced him to 12 months in jail. Biro now appeals.
ANALYSIS
I. Motion to Dismiss
Biro contends that the circuit court erred by denying his motion to dismiss for not
preserving exculpatory evidence. Biro specifically argues that the surveillance system captured
the events in the jail that led to his charges but that the officers and Commonwealth purposefully
did not preserve the video files. He thus declares that, not only did this violate his due process
rights, but absent a contrary showing, we must assume that the officers were acting in bad faith.

ANALYSIS
I. Motion to Dismiss
Biro contends that the circuit court erred by denying his motion to dismiss for not
preserving exculpatory evidence. Biro specifically argues that the surveillance system captured
the events in the jail that led to his charges but that the officers and Commonwealth purposefully
did not preserve the video files. He thus declares that, not only did this violate his due process
rights, but absent a contrary showing, we must assume that the officers were acting in bad faith.
-4- In response, the Commonwealth contends that “[i]nadvertently failing to properly mark
the video for preservation does not establish bad faith” and that Biro did not prove that the
destroyed evidence was exculpatory. We agree.
Constitutional issues present questions of law reviewed de novo on appeal. Wallace v.
Commonwealth, 65 Va. App. 80, 88 (2015), aff’d, 292 Va. 1 (2016). “To the extent such review
involves underlying factual findings, those findings may not be disturbed unless ‘plainly wrong’
or ‘without evidence to support them.’” Ali v. Commonwealth, 75 Va. App. 16, 33 (2022)
(quoting Wilkins v. Commonwealth, 292 Va. 2, 7 (2016)).
The Due Process Clause of the Fourteenth Amendment entitles an accused to exculpatory
evidence in the prosecution’s possession. Martinez v. Commonwealth, 42 Va. App. 9, 26 (2003).
Thus, under Brady v. Maryland, 373 U.S. 83 (1963), and its progeny, “due process requires that
the prosecution disclose evidence favorable to the accused that is material to guilt or
punishment.” Church v. Commonwealth, 71 Va. App. 107, 117 (2019).
When, as here, the issue relates to evidence no longer in the government’s possession,
whose exculpatory value is unknown, California v. Trombetta, 467 U.S. 479 (1984), and Arizona
v. Youngblood, 488 U.S. 51 (1988), govern.1 Under both,
1 Gagelonia v. Commonwealth, 52 Va. App. 99 (2008), accurately condensed both cases:
In Trombetta, . . . the United States Supreme Court held that “the government violates due process if the evidence possessed ‘exculpatory value that was apparent before the evidence was destroyed, and the evidence is of such a nature that the defendant would be unable to obtain comparable evidence by any other reasonable means.’” Park v. Commonwealth, 32 Va. App. 407, 420 (2000) (quoting Trombetta, 467 U.S. at 489). In Youngblood, the Court added a third requirement, holding that if “a criminal defendant can[not] show bad faith on the part of the police, failure to preserve potentially useful evidence does not constitute a denial of due process of law.” 488 U.S. at 58.
Id. at 114-15 (second alteration in original). -5- a defendant seeking a new trial on the basis of missing evidence formerly in the Commonwealth’s possession must show that (1) the evidence possessed an apparent exculpatory value, (2) the defendant could not obtain comparable evidence from other sources, and (3) the Commonwealth, in failing to preserve the evidence, acted in bad faith.
Gagelonia v. Commonwealth, 52 Va. App. 99, 115 (2008). Biro’s claim fails because he has
shown neither the apparent exculpatory value of the destroyed evidence nor bad faith from the
Commonwealth.
Biro’s argument that the jail surveillance video was apparently exculpatory when it was
destroyed is speculative. He relies entirely on an assumption that the video would show that any
contact was accidental and that his feet were shackled preventing him from kicking Matthews.
This raises no more than the possibility that the footage could have exculpated him. Matthews
and Collins testified that they and two other officers were present for the incident, all of whom
could testify and face cross-examination. And the Commonwealth provided Biro with
Matthews’s and Collins’s reports about the incident. For these reasons, we find that Biro has not
shown that the footage “possessed an apparent exculpatory value” before it was destroyed. Id.
Biro also cannot prove bad faith. Whether bad faith exists “necessarily turn[s] on the
police’s knowledge of the exculpatory value of the evidence [when] it was lost or destroyed.” Id.
(quoting Youngblood, 488 U.S. at 56 n.*). Requiring a showing of bad faith not only limits “the
police’s obligation to preserve evidence to reasonable bounds,” but also confines due process to
cases where the police’s conduct itself suggests that the evidence could “form a basis for
exonerating the defendant.” Youngblood, 488 U.S. at 58.
When the circuit court denied Biro’s motion to dismiss, it said:
[I]f you have evidence that either the prosecutor or the defense requested it to be preserved within [30 days] and they didn’t preserve it, maybe you have a situation of bad faith, but it’s a video that nobody asked for [within 30 days] and I don’t think you can equate not asking for it with bad faith. . . . [Both sides] know it’s -6- an event at the jail. You know that the jail has video cameras, so clearly an effort can be made to at least inquire or ask that they be preserved.
In other words, there was no showing that “anyone was aware that someone wanted this video
and then, according to their policy, just let it get taped over or destroyed after 30 days.” The
court accordingly found no bad faith.
We cannot say that the trial court’s finding was plainly wrong or without evidence to
support it. See Lovitt v. Warden, 266 Va. 216, 241 (2003) (“The circuit court’s determination
that there was an absence of bad faith was a finding of fact, not of law . . . . Such factual
findings made by the circuit court are entitled to deference and are binding in this proceeding
unless they are plainly wrong or without evidence to support them.”). Although Matthews is
correct that not preserving the footage was an “oversight on [his] part,” that is not the test—bad
faith must exist. But the jail was not selective in the evidence it destroyed. According to policy,
it automatically destroyed all surveillance footage after 30 days unless there was a preservation
request. Neither the Commonwealth nor Biro lodged such a request despite litigating the charges
since April 2023. And Matthews testified that he does not have direct access to the surveillance
footage at the jail like he does in the sheriff’s office, so he too must go through the jail custodian
of records. In any event, the essence of Biro’s argument here is that the jail following its
procedure—because there was no request from the Commonwealth, Matthews, or Biro—
constituted bad faith from the Commonwealth. This argument is unavailing.
We accordingly affirm the circuit court’s denial of Biro’s motion to dismiss for failure to
preserve exculpatory evidence. The apparent exculpatory value of the footage is speculative at
best, and the record supports the trial court’s finding that there was no bad faith from the
-7- II. Amending the Indictment
Biro next challenges the circuit court’s power to sua sponte amend the indictment for
assault and battery of a law enforcement officer under Code § 18.2-57(C) to obstruction of
justice under Code § 18.2-460(B). He also argues that the amendment violated Code § 19.2-231
because it “changed the nature or character of the offense charged.”2 While Biro’s arguments
raise interesting, and frankly important, questions about the circuit court’s power, he did not
properly preserve them for appeal.
Rule 5A:18 provides that “[n]o ruling of the trial court . . . will be considered as a basis
for reversal unless an objection was stated with reasonable certainty at the time of the ruling,
except for good cause shown or to enable this Court to attain the ends of justice.” The Rule
serves “to ensure that litigants ‘make timely and specific objections, so that the trial court has an
opportunity to rule intelligently on the issues presented, thus avoiding unnecessary appeals and
reversals.’” Hannah v. Commonwealth, 303 Va. 109, 124-25 (2024) (quoting Brown v.
Commonwealth, 279 Va. 210, 217 (2010)). Thus, “[i]t is the appellant’s burden ‘to obtain a clear
ruling from the trial court’ on an issue he wishes to raise on appeal.” McDaniel v.
Commonwealth, 73 Va. App. 299, 313 (2021) (quoting Young v. Commonwealth, 70 Va. App.
646, 657 (2019)).
When objecting, “the parties must inform the circuit court ‘of the precise points of
objection in the minds of counsel’”; a general argument or an abstract legal reference is
insufficient to preserve an issue for appeal. Maxwell v. Commonwealth, 287 Va. 258, 265 (2014)
2 Biro adds that the amendment “plainly operated as a surprise to [Biro] and his counsel, yet the trial court did not offer or afford Biro any opportunity for a continuance to prepare a defense to the newly amended charge.” To Biro, this was a denial of due process. Code § 19.2-231 only entitles a defendant to a reasonable continuance “upon request” and if the court finds that the amendment “operates as a surprise.” (Emphasis added). Biro never requested a continuance. So, even if the issue were properly preserved, this fact would be fatal to his claim. -8- (emphasis added) (quoting Gooch v. City of Lynchburg, 201 Va. 172, 177 (1959)); accord
Edwards v. Commonwealth, 41 Va. App. 752, 760 (2003) (en banc).3 Here, neither Biro nor his
counsel contested the court’s authority to sua sponte amend the indictment during trial. Indeed,
Biro’s counsel said, “Judge, . . . I understand what the Commonwealth is saying and I get what
the [c]ourt has done here.” Biro and his counsel also did not raise whether the amendment
changed the nature or character of the offense charged; they merely questioned whether it was a
proper amendment if obstruction of justice is not a lesser-included offense of assault and battery
of a law enforcement officer. We therefore cannot say that Biro specified “the precise points of
objection,” or allowed the trial court to rule on either issue. Maxwell, 287 Va. at 265.
What is more, making one specific argument on an issue does not preserve a separate
legal point on the same issue for review. See Clark v. Commonwealth, 30 Va. App. 406, 411-12
(1999). “Procedural-default principles require that the argument asserted on appeal be the same
as the contemporaneous argument at trial.” Bethea v. Commonwealth, 297 Va. 730, 743 (2019).
At trial, Biro argued that the amendment was improper because obstruction of justice is not a
lesser-included offense of assault and battery of a law enforcement officer. This argument
cannot extend on appeal to whether the trial court had the power to amend the indictment or
whether the amendment changed the nature or character of the offense.
To be sure, in limited circumstances, Rule 5A:18 allows this Court to consider a matter
not preserved by objection in the trial court for good cause or to meet the ends of justice. See
Commonwealth v. Bass, 292 Va. 19, 27 (2016). But Biro does not raise either exception
recognized by Rule 5A:18; his brief is void of reference to good cause or the ends of justice.
3 The objection must also come “at a point in the proceeding when the trial court is in a position, not only to consider the asserted error, but also to rectify [its] effect.” Maxwell, 287 Va. at 265 (quoting Scialdone v. Commonwealth, 279 Va. 422, 437 (2010)). -9- And as we have said on many occasions, this Court will not invoke either exception sua sponte.
See Edwards, 41 Va. App. at 761; Hannah, 303 Va. at 125; see also Rule 5A:20(e).
We accordingly find that Biro waived his ability to challenge on appeal the circuit court’s
authority to sua sponte amend his indictment during trial. He also waived any argument that the
amendment violated Code § 19.2-231 by changing the nature or character of the offense charged.
CONCLUSION
Biro’s claim that the circuit court erred in denying his motion to dismiss fails because he
has shown neither the apparent exculpatory value of the destroyed evidence nor bad faith from
the Commonwealth. Additionally, Biro waived his ability to challenge the amended indictment
on appeal. We therefore affirm Biro’s conviction.
Affirmed.
