Core Event
Contra Costa Superior Court Judge Nichelle Holmes ordered the release of Marcos Iriarte-Valdez, a Venezuelan national who also holds Spanish citizenship, on his own recognizance after he violated the terms of pre-trial home detention for burglary charges. Within roughly 24 hours of that release, Iriarte-Valdez allegedly stabbed Todd Stewart, a 68-year-old Martinez resident, to death during an attempted burglary. Iriarte-Valdez is now being held without bail, with a bail amount set at $1.1 million, and is scheduled to appear in court on Tuesday, September 1.
Background & Context
Judge Holmes was appointed to the Contra Costa Superior Court by Governor Gavin Newsom in 2024 after serving as a deputy district attorney from 2012 to 2024. In a 2017 interview with her alma mater, the University of San Francisco School of Law, Holmes described her approach to criminal justice as a form of protest, emphasizing alternatives to incarceration. The release occurred amid ongoing political debate in California over “sanctuary” policies that limit cooperation with federal immigration enforcement.
Data & Statistics
- Iriarte-Valdez has a prior criminal record and faced multiple burglary charges in Contra Costa County.
- The homicide charge includes three enhancements: a special circumstance for a murder occurring during or immediately after a burglary, use of a deadly weapon (knife), and commission of the offense while released on bail or recognizance.
- The Department of Homeland Security (DHS) classified Iriarte-Valdez as an “illegal alien” despite his legal admission to the United States in 2007.
Conflicting Reports & Gaps
- DHS initially described Iriarte-Valdez as an “illegal alien” but later clarified that he was “legally admitted” to the United States in 2007.
- The Department’s public statements varied between labeling the individual an “illegal alien” and acknowledging his legal admission, creating uncertainty about his immigration status at the time of the release.
