California Judge Released Suspect Before Martinez Killing

A California judge released Marcos Iriarte-Valdez before the Martinez killing of Todd Stewart, prompting new scrutiny of the state’s release and sanctuary policies.

A California judge released a burglary suspect in the Bay Area one day before prosecutors say he killed a 68-year-old man in Martinez. The case has put a fresh spotlight on the California judge decision that freed Marcos Iriarte-Valdez before the death of Todd Stewart, a retired resident who had lived on his quiet street for about 40 years.

According to prosecutors, Iriarte-Valdez was already facing burglary charges tied to at least two incidents elsewhere in Contra Costa County when he was ordered released on his own recognizance. He had been on pretrial release in that case when he was arrested Tuesday for allegedly violating a home-detention condition. A judge then released him Wednesday, and prosecutors say Stewart was killed the next day during an attempted burglary. Authorities say Iriarte-Valdez ran from Stewart’s residence after Stewart encountered him in a garage, then stabbed and killed him. He is now being held without bail and is scheduled to appear in court Wednesday.

The Department of Homeland Security said it placed an immigration detainer on Iriarte-Valdez on Saturday, Sept. 23, 2025. In a statement, the department said he faces murder, inflicting corporal injury on spouse, three counts of burglary, receiving known stolen property, trespassing, entering a non-commercial dwelling, loitering, and a conviction for violating a court-ordered protective order. DHS also said he was legally admitted to the United States during the George W. Bush administration but has since been classified as an illegal alien. Fox News Digital sought clarification from the department on that point.

DHS used the case to argue that sanctuary policies are putting the public at risk. The department said sanctuary politicians are placing politics above safety and claimed that criminal illegal aliens are being released from jails and sent back into American communities. A DHS spokesperson also said the safest way to arrest and remove criminal illegal aliens is by lodging arrest detainers, and said Homeland Security Secretary Markwayne Mullin continues to target the worst of the worst.

The killing has also rattled one homeowner who said he had been targeted by Iriarte-Valdez during the alleged April burglary spree. Speaking to FOX’s San Francisco affiliate, the homeowner said his 83-year-old wife saw Iriarte-Valdez’s reflection and screamed, after which he believed the suspect took off. The man also said he accepted that a judge had discretion in the release decision, even as he expressed shock that Iriarte-Valdez was back on the street.

Records in the case show a troubling sequence: burglary allegations, pretrial release, a later arrest for a possible home-detention violation, and then another release before a deadly confrontation. Contra Costa County sits just east of San Francisco, in a Democratic-majority region where immigration enforcement and local cooperation with federal authorities have become a sharp political fault line. The Martinez case now adds to a broader national fight over how courts handle repeat offenders and whether local officials should honor federal immigration detainers.

Fox News Digital said it reached out to the Martinez Police Department, Contra Costa Superior Court, District Attorney Diana Becton’s office, and California Gov. Gavin Newsom for comment. For Americans watching this case, the question is simple: whether dangerous suspects are being kept off the streets or sent back into neighborhoods before the public is protected.
