CRIMINAL ACTION

No. 03-554

MEMORANDUM

Chief Judge Juan R. Sánchez January 6, 2023

In February 2017, this Court issued a warrant for Defendant Carlos Perez for violating the 

terms of his supervised release, based in part on his arrest by local authorities on homicide charges. 

Perez now moves to dismiss the warrant and to terminate his supervised release based on his 

acquittal of the underlying crime in state court. In the alternative, Perez argues Magistrate Judge 

Thomas J. Rueter’s finding that there was probable cause Perez violated his supervised release was 

based on misleading evidence. Because this Court can rely on acquitted conduct to adjudicate a 

violation of supervised release, and because Judge Rueter’s probable cause finding was justified, 

the Motion to Dismiss the Warrant will be denied. 

FACTS

On February 23, 2017, while Perez was on federal supervised release, the Philadelphia 

Police Department arrested and charged him with homicide and possession of an instrument of 

crime. VOSR Report & Order 2, ECF No. 138. The next day, the U.S. Probation Office filed a 

Report recommending the Court issue a warrant for violation of supervised release (“VOSR”). Id. 

at 3. The Report listed two violations: committing a crime and associating with a convicted felon. 

Id. at 2. It stated, “[a]ccording to Affidavit of Probable Cause, the defendant was identified as the 

perpetrator [of the homicide] through witness statements and D.N.A. evidence.” Id. On March 22,

2017 and April 5, 2017, two different judges dismissed the state charges against Perez. Second 

Mot. Dismiss ¶ 3 n.1, ECF No. 175. 

On April 13, 2017, Judge Rueter presided over Perez’s probable cause hearing for the

VOSR warrant. Bail Status & Order, ECF No. 140. At the hearing, the Probation Officer adopted 

the Affidavit of Probable Cause (the “Affidavit”) and said he had not received the notes of 

testimony from the state hearings. Tr. VOSR Hr’g 18:1-4, 21:25-22:5, ECF No. 153. He also 

testified that his information regarding the second violation, associating with a convicted felon, 

came from the Police Department. Id. at 12:22-13:9, 15:15-17. The Government relied on the 

Affidavit and Probation’s Report at the hearing. Gov’t’s Opp’n Def.’s First Mot. Dismiss 11, ECF 

No. 159. Of the evidence presented, three items are relevant herein. First, the Probation Officer 

testified that the District Attorney told him there was video surveillance identifying Perez. Tr. 

VOSR Hr’g 20:24-21:7, ECF No. 153. Second, the Probation Officer and the Government both 

testified that DNA testing showed Perez’s t-shirt had the victim’s blood on it. Id. at 19:10-13, 

24:15-17. Third, the Affidavit stated Perez was identified through witness statements, including a 

photo spread identification. VOSR Report & Order 2, ECF No. 138; see also Tr. VOSR Hr’g 

23:16-18, ECF No. 153. Judge Rueter found there was probable cause Perez had violated a 

condition of his supervised release based on the Affidavit and the photo spread identification. Tr. 

VOSR Hr’g 31:8-16, ECF No. 153. 

In October 2019 the Pennsylvania Superior Court affirmed the trial court’s dismissal of the 

state charges in the Superior Court. Second Mot. Dismiss ¶ 3 n.1, ECF No. 175. The 

Commonwealth then appealed to the Pennsylvania Supreme Court, which found probable cause, 

overturned the lower courts, and remanded the case on April 28, 2021. Id. Perez was acquitted of 

all charges at trial on November 18, 2021. Id.

PROCEDURAL HISTORY

On August 14, 2017, while the state charges were on appeal, Perez filed a Motion to 

Dismiss the First Ground for the Warrant for VOSR.1 After briefing by the parties, this Court 

continued argument on the matter while the state case was pending. Second Mot. Dismiss ¶ 8, ECF 

No. 175. On December 20, 2021, following his acquittal in state court, Perez filed a new Motion 

to Dismiss the Warrant and Terminate Supervised Release. The Government filed its Response in 

Opposition on April 20, 2022, and Perez filed a Reply on June 13, 2022. This Court held oral 

argument on November 21, 2022. 

STANDARD OF REVIEW

Before a court can revoke supervised release, a magistrate judge must conduct a 

preliminary hearing “to determine whether there is probable cause for the alleged violation of 

supervised release.” United States v. Robertson, 367 F. App’x 301, 304 (3d Cir. 2010)

(unpublished opinion). When reviewing a magistrate judge’s probable cause finding, a District 

Court should “simply ensure that the magistrate had a substantial basis for . . . conclud[ing] that 

probable cause existed.” United States v. Conley, 4 F.3d 1200, 1205 (3d Cir. 1993) (internal 

quotation marks and citation omitted). This review is highly deferential. Id.

DISCUSSION

Perez challenges the warrant for VOSR under two theories, both of which fail. The Court 

will address each in turn. 

1 Perez made two arguments in this Motion. First, he argued principles of comity, abstention, and 

preclusion counseled against adjudication of the VOSR. First Mot. Dismiss 3-7, ECF No. 157. At 

oral argument, however, Perez abandoned these arguments. Second Mot. Dismiss Hr’g, Nov. 21, 

2022 (not transcribed). Second, Perez argued the warrant for VOSR was issued based on false 

statements and mischaracterized evidence. First Mot. Dismiss 7-10, ECF No. 157. The Court has 

considered this second set of arguments, and the Government’s corresponding arguments in its 

Response, as incorporated into the filings for the Motion to Dismiss currently at issue.

First, Perez argues the warrant should be dismissed based on his acquittal in state court. 

Sentencing courts such as this one, however, can rely on acquitted conduct in applying the 

Sentencing Guidelines so long as the conduct is proven by a preponderance of the evidence. United 

States v. Watts, 519 U.S. 148, 157 (1997). Perez concedes this rationale applies. Reply Supp. 

Second Mot. Dismiss 1, ECF No. 184. At oral argument, he also argued the Supreme Court of 

Pennsylvania would not have found probable cause if it had known about additional facts which 

came out at trial. Second Mot. Dismiss Hr’g, Nov. 21, 2022 (not transcribed). But this argument 

is speculative, as it is difficult to hypothesize about what a court would or would not have done. 

Because Perez’s acquittal in the state court (a) does not bar this Court’s adjudication of the first 

VOSR charge (committing another crime) and (b) does not bear on the second VOSR charge

(associating with a convicted felon), the Court rejects Perez’s first argument. 

In the alternative, Perez argues the warrant should be dismissed because Judge Rueter’s 

probable cause finding was based on incorrect and misleading information, specifically (1) the 

video surveillance, (2) the DNA evidence, and (3) the witness identifications. Reply Supp. Second 

Mot. Dismiss 1, ECF No. 184. Because Perez has not shown Probation or the Government

knowingly and intentionally, or with reckless disregard for the truth, used any false statements to 

obtain the probable cause finding, this argument fails. Even if Perez could make this showing, the 

Court finds the challenged evidence is not persuasive enough to disturb Judge Rueter’s finding. 

“[A] defendant may attack the issuance of a warrant if based on untruthful information.”2

United States v. Harvey, 2 F.3d 1318, 1323 (3d Cir. 1993). However, a warrant need not be 

2 The Third Circuit has not decided if warrants for VOSR must satisfy the Fourth Amendment’s 

requirements that “no Warrants shall issue, but upon probable cause, supported by Oath or 

affirmation.” See United States v. Petlock, 843 F. App’x 441, 444 (3d Cir. 2021) (unpublished 

opinion) (“Courts disagree about whether this requirement extends to warrants issued for violating 

Case 2:03-cr-00554-JS Document 188 Filed 01/06/23 Page 4 of 7

“‘truthful’ in the sense that every fact recited in the warrant affidavit is necessarily correct, for 

probable cause may be founded upon hearsay and upon information received from informants.” 

Franks v. Delaware, 438 U.S. 154, 165 (1978). To successfully attack a warrant on this basis, a 

defendant must show the warrant affidavit included a false statement made knowingly and 

intentionally, or with reckless disregard for the truth. Id. at 155-56. The defendant must make this 

showing by a preponderance of the evidence. Id. Then, if the false statement was necessary to the 

probable cause finding and the “remaining content is insufficient to establish probable cause, the . 

. . warrant must be voided.” Id.

Perez’s attack on Judge Rueter’s probable cause finding fails at the first step. He argues 

the Probation Office “either intentionally or inadvertently mischaracterized, omitted or falsified 

the evidence” and the Government “went along with that mischaracterization.” First Mot. Dismiss 

7, ECF No. 157. Because Perez concedes the mischaracterization may have been inadvertent, on 

its face, this argument does not show a knowing and intentional falsification or reckless disregard 

for the truth. And despite his suggestion otherwise, there is no evidence the Affidavit of Probable 

Cause, which provided the primary basis for Probation’s Report, was intentionally and knowingly 

falsified or made with reckless disregard for the truth. Neither Probation nor the Government had

any information belying the Affidavit at the time of the hearing. Tr. VOSR Hr’g 21:25-22:5, ECF 

No. 153; Gov’t’s Opp’n Def.’s First Mot. Dismiss 11, ECF 159. This fact is enough to defeat 

Perez’s argument. 

a condition of supervised release. We, however, need not decide this question, because the papers 

here would satisfy the oath or affirmation requirement if it did apply.” (Footnote omitted.)).

Because it is sufficiently analogous – and for lack of any other legal test – the Court will apply a 

Fourth Amendment analysis to Perez’s Motion.

Even if Perez could make the required showing, his challenge to the video surveillance, 

DNA evidence, and witness identifications does not persuade the Court that probable cause was 

lacking. Perez first notes there was no video surveillance of the homicide, contrary to testimony at 

the hearing. First Mot. Dismiss 9, ECF No. 157. But Judge Rueter did not rely on the video 

surveillance to find probable cause that Perez committed a crime. Tr. VOSR Hr’g 31:8-14 (“Based 

on this affidavit, there’s probable cause . . . and you haven’t impeached the photo spread.”), ECF 

No. 153. Second, Perez argues the Government’s testimony regarding the blood on his t-shirt was 

misleading because there was also blood on other people and “all over the club.” First Mot. Dismiss 

9, ECF No. 157. This argument mischaracterizes the proceedings: the Government did not make 

any false statements, and defense counsel noted the victim “bled everywhere.” Tr. VOSR Hr’g 

28:4, ECF No. 153. Third, Perez argues he was never identified by any witnesses, contrary to 

Probation’s Report and testimony at the hearing. First Mot. Dismiss 8, ECF No. 157. During the 

hearing, defense counsel impeached Perez’s identification by several witnesses, as Judge Rueter 

acknowledged. Tr. VOSR Hr’g 22:6-9, 26:15-25, 31:9-12, ECF No. 153. But counsel did not 

impeach a witness who identified Perez in a photo spread. See id. at 23:13-21, 31:12-14, ECF No. 

153. Despite the identification, at other times the witness stated “he could not identify anyone in 

the club . . . and did not even know if it was a man or a woman who stabbed [the victim].” First 

Mot. Dismiss 10, ECF No. 157. The Court acknowledges Judge Rueter relied on this identification. 

Tr. VOSR Hr’g 31:12-14, ECF No. 153.

Even if the Court takes the photo spread out of consideration, Judge Rueter’s probable 

cause finding was justified based on the remaining evidence. Perez was arrested based on 

circumstantial evidence, and the Report cited this arrest. See United States v. Brennan, 285 F. 

App’x 51, 56 (4th Cir. 2008) (unpublished opinion) (“The petition for the warrant [for VOSR] 

Case 2:03-cr-00554-JS Document 188 Filed 01/06/23 Page 6 of 7

identified the specific condition that Brennan allegedly violated—the no-other-crimes condition—

and provided the date and location of Brennan’s arrest, as well as the charge upon which he was 

arrested. This was sufficient to establish probable cause to believe Brennan violated his conditions 

of supervised release.”). Though the charges had been dismissed by a state court, an appeal was 

pending. Moreover, Perez does not attack the second violation charged, associating with a 

convicted felon. This violation is enough, standing on its own, to support a finding of probable 

cause that Perez violated the terms of his supervised release. 

As a final consideration, Perez argues that holding a revocation hearing would not serve 

the purposes of supervised release. Reply Supp. Second Mot. Dismiss 4, ECF No. 184. Perez is 

now a married father with three children who also cares for his elderly mother. Id. at 3. He owns 

five successful businesses, is a licensed general contractor, and mentors vulnerable youth. Id. at 2.

Though the Court commends Perez for these accomplishments, this policy argument cannot 

overcome the severity of the charged violations and the lack of a legal basis to support dismissal.

Therefore, the Court will deny Perez’s Motion to Dismiss the Warrant.
