A U.S. Customs and Border Protection officer who allegedly used his gun and badge to rape multiple women is asking a judge to toss his indictment because it was returned by the same grand jury allegedly “indoctrinated” through the feds’ misconduct in the “Broadview Six” case.
Not only that, but a key witness against Luis Uribe testified before the grand jury the same day some of the alleged “Broadview Six” misconduct occurred, according to defense attorney Michael Clancy.
However, the veteran prosecutor at the center of the “Broadview Six” controversy did not handle the case against Uribe, who faces trial Sept. 8 on charges contained in an 11-count indictment handed up in December.
Federal prosecutors say Uribe committed multiple “gunpoint sexual assaults” of four women in Schaumburg and Naperville between February and October 2022. He’s been held in federal custody since his Dec. 9 arrest, records show.
Clancy on Monday asked U.S. District Judge Jorge Alonso to dismiss the indictment against Uribe. In the alternative, Clancy asked the judge to hold a hearing and order prosecutors to hand over grand jury materials.
Alonso could take up the request Wednesday, when a pretrial conference is set to take place. The feds have yet to respond directly to Clancy’s request.
After a similar challenge was made in a separate case last month, prosecutors told a judge there was no reason to believe one prosecutor’s misconduct “so infected other grand jury sessions to render them void.”
Still, 10 people in three cases have seen their charges dropped as a result of the apparent misconduct uncovered in the “Broadview Six” case — the collapsed prosecution of six Operation Midway Blitz protesters.
U.S. District Judge April Perry has yet to rule on a bid for sanctions or a special counsel in that case. Clancy argued Monday that the full extent of misconduct by the veteran prosecutor at the center of the controversy “will never be known without discovery and an evidentiary hearing.”
The prosecutor in question is Assistant U.S. Attorney Sheri Mecklenburg who, on Oct. 9, allegedly engaged in a forbidden practice in the “Broadview Six” case known as “vouching.”
It’s improper, and it occurs when a prosecutor puts her personal credibility on the line to push for criminal charges.
Mecklenburg told the panel, “I want to go in front of the Thursday grand jury because I know you and I trust you and you know me and you trust me, and I would never ask you to charge somebody if I didn’t think there was probable cause and you know you’ve asked me before, ‘Well, what about this person?’ And I said, ‘I don’t charge people unless I’m absolutely sure.’”
That left the grand jury “hopelessly tainted,” Clancy argued.
Meanwhile, the defense attorney pointed to other “possible misconduct” — or “at the very least irregularities” — that occurred the same day as Mecklenburg’s alleged misconduct.
An alleged victim in Uribe’s case testified before the same grand jury with help from a Mandarin interpreter, Clancy wrote. At some point, prosecutors decided the interpreter’s translation was inaccurate.
There’s an audio recording of the testimony, Clancy wrote, but no official court reporter’s transcript. Instead, prosecutors turned over “a later FBI translation and transcript that the United States Attorney’s Office has deemed accurate,” Clancy said.
“Thus, on Oct. 9, 2025, on the same afternoon that [Mecklenburg] egregiously indoctrinated the Special June 2024 grand jury, that same grand jury also heard mistranslated questions and answers by [the alleged victim] in Uribe’s case,” Clancy wrote.
“The later FBI translation and transcript do not cure the gross error of the grand jury receiving mistranslated testimony.”
