In Southern California’s federal courts, criminal cases are running headfirst into an aggressive immigration dragnet, and some of those prosecutions are simply falling apart. Defendants who had been released on bond are being picked up by immigration agents and shuffled into ICE custody, cutting them off from their lawyers and throwing carefully built prosecutions into disarray. Judges are now entertaining, and in some instances granting, dismissal motions that bring months or years of work to an abrupt halt, leaving victims and prosecutors with little to show for it.
Judge Dismisses Indictment After ICE Detains Defendant
U.S. District Judge Dolly M. Gee tossed the indictment against Guillermo Zambrano with prejudice after ICE detained him and failed to return him to the pretrial release conditions she had ordered, according to the Los Angeles Times. Court filings show Zambrano had been out on a $60,000 bond and wearing an ankle monitor until officers took him into custody on June 24, 2025, and removed the device.
Gee warned prosecutors that unless the custody issue was fixed, she would dismiss the case, noting in court that “this is not a one-off. this is happening repeatedly.” When the situation was not corrected, she followed through and ended the prosecution.
Adelanto Detention Cuts Off Access To Counsel
In a separate case, another federal judge threw out an indictment after finding that a defendant held at the Adelanto ICE Processing Center could not adequately meet with defense counsel ahead of trial, the Guardian reported. The court pointed to the distance to Adelanto, scheduling obstacles and the facility’s procedures as a mix of barriers that effectively blocked the defendant’s meaningful access to a lawyer.
Those restrictions, the judge concluded, had materially damaged the defendant’s Sixth Amendment right to counsel and hampered the defense team’s ability to review and discuss discovery before trial.
Deportation Ended A High‑Profile $100M Case
Prosecutors also say one defendant connected to what authorities described as the largest jewelry heist in U.S. history was deported to Ecuador while awaiting trial, a decision that court filings state effectively ended the nearly $100 million Brinks semitruck case, according to the Los Angeles Times. Victims and their attorneys said they were stunned to learn a suspect had been removed from the country while the government was still trying to bring the case to court.
Courts Say The Executive Branch Must Coordinate
Judges and defense lawyers say the constitutional problem is straightforward. When ICE removes a defendant, transfers them far from the courthouse or places them in a facility that sharply limits attorney visits, the person may lose meaningful assistance of counsel and a fair chance to review evidence. Legal summaries and prior district court rulings collected by CaseMine show that courts have, at times, dismissed indictments where detention or removal made representation effectively impossible or where agency decisions clashed with judicial release orders.
What Comes Next
Prosecutors say they intend to appeal the dismissals and push for better coordination with immigration authorities so that criminal cases are not derailed midstream. Defense attorneys counter that the rulings simply reinforce core constitutional protections for people in custody.
For victims and for local prosecutors, the stakes are blunt. Without clearer rules on how immigration removal decisions interact with criminal court calendars, long-running investigations and efforts to secure restitution can be upended by a single transfer or deportation.
