A 36-year-old Venezuelan national already facing burglary charges allegedly stabbed a 68-year-old father to death outside his Contra Costa County home, less than 24 hours after a California judge let him walk free.
Marcos Iriarte-Valdez now faces a felony murder charge with three sentencing enhancements after prosecutors say he killed Todd Stewart during a residential burglary on August 6. Security camera footage released by the Department of Homeland Security shows a man exiting an SUV in a tactical vest, then wrestling Stewart over a knife outside Stewart's home in broad daylight. Stewart did not survive.
The timeline is damning on its own terms. Iriarte-Valdez had been arrested in April on two counts of residential burglary. A judicial officer named David E. Goldstein released him on pretrial supervision. The very next day, the Daily Caller reported, Iriarte-Valdez allegedly carried out the fatal attack on Stewart. Bail on the murder charge now sits above $1 million.
Court records show Goldstein, the same judicial officer who approved Iriarte-Valdez's pretrial release, has been assigned to the new murder case. The records also list the three enhancements prosecutors added to the murder charge: killing during a burglary, use of a knife, and committing a crime while on conditional release. That last enhancement exists precisely because the system is supposed to treat defendants on supervised release as higher risks. In this case, the system failed before the ink on the release order was dry.
Iriarte-Valdez has denied all charges, Contra Costa County said in a public statement.
Contra Costa County District Attorney Diana Becton addressed the case publicly. She told ABC7 Eyewitness News that her office would:
"pursue this case with diligence and integrity to hold Iriarte-Valdez fully accountable under the law for this devastating act of violence."
Becton's pledge of accountability is worth watching. The question voters and Stewart's family will ask is not whether the DA's office pursues the murder charge aggressively, it is why Iriarte-Valdez was on the street at all. A man arrested for two residential burglaries walked out of custody and, within a day, allegedly committed a far worse crime at another residence. That sequence is not a fluke. It is a policy result.
California's pretrial release framework has drawn sustained criticism from law enforcement and victims' advocates who argue it returns dangerous defendants to the community too quickly. This case hands those critics a concrete, fatal example. The incident also echoes a broader pattern of violent encounters involving foreign nationals that have fueled public frustration with enforcement gaps at every level of the system.
On August 11, DHS posted the security camera footage on its official account and issued a blunt public demand aimed at California Governor Gavin Newsom:
"This Venezuelan illegal alien STABBED A FATHER TO DEATH in sanctuary California. @CAgovernor must NOT RELEASE this murderer from jail and turn him over to us so we can REMOVE him from our nation."
ICE has placed a detainer on Iriarte-Valdez. DHS told ABC7 that the suspect is a Venezuelan national who also holds Spanish citizenship. Whether California honors that detainer remains an open question, and a politically charged one. The state's sanctuary policies have long restricted local cooperation with federal immigration enforcement, a stance that puts Sacramento directly at odds with DHS when cases like this land in the headlines.
Newsom has not publicly responded to DHS's demand. The governor's silence leaves unanswered whether the state will facilitate a transfer to federal custody or allow its sanctuary framework to shield a man now charged with murder. That tension between state policy and federal enforcement is not new, but it takes on a sharper edge when the defendant was already in custody on serious charges and walked free into an alleged killing.
The federal government has grown increasingly vocal about what it sees as California's obstruction of immigration enforcement. DHS's decision to release the surveillance footage and publicly name the governor reflects an escalation in that pressure campaign. Similar friction has surfaced in cases involving foreign nationals with prior contact with the immigration system who later faced serious criminal charges.
The security footage paints a grim picture of Stewart's final moments. DHS described it as showing Iriarte-Valdez exiting an SUV wearing a tactical vest, then engaging in a physical struggle with Stewart over a knife outside Stewart's home. The 68-year-old was outmatched. He died from his injuries.
DHS identified Stewart as a father. The agency's statement framed the killing as a direct consequence of California's approach to both pretrial release and immigration enforcement, a framing the facts make difficult to dismiss.
Several questions remain unanswered. Did the court know Iriarte-Valdez's immigration status when it approved his pretrial release? What specific conditions, if any, were attached to that release? And what was the basis for DHS's claim that the suspect holds dual Venezuelan-Spanish citizenship? None of these details appear in the public record so far.
The case also raises a structural concern. When a defendant charged with two residential burglaries is released and then allegedly commits a fatal residential burglary within 24 hours, the system has not merely failed to protect the public, it has actively returned a specific, documented threat to the very environment where he had already allegedly offended. The enhancement for committing a crime while on conditional release exists as a sentencing tool after the fact. It does nothing for Todd Stewart.
Violent crime committed by individuals who were already in the justice system's hands continues to generate public outrage, particularly when the victims are vulnerable. A recent stabbing death in Los Angeles drew similar scrutiny over whether the system had done enough to prevent a foreseeable act of violence.
Becton's office will now prosecute a murder that, by the state's own records, happened one day after the state's own court turned the defendant loose. The DA has promised full accountability. But accountability for the killing is only half the ledger. The other half belongs to the pretrial release decision itself, and to the broader policy architecture that treats public safety as an acceptable trade-off for reducing jail populations.
California's political leadership has spent years defending sanctuary policies and pretrial reforms as humane, progressive, and necessary. Todd Stewart's family is now living with the consequences of those choices. DHS wants Iriarte-Valdez transferred to federal custody. Whether Sacramento cooperates or hides behind its sanctuary framework will tell voters everything they need to know about whose safety the state actually prioritizes.
The political class that built this system rarely lives in the neighborhoods where its failures land. The people who do, people like Todd Stewart, don't get a second chance to survive the experiment.
