Overview
- A 68-year-old Martinez resident, Todd Stewart, was found fatally stabbed outside his home after multiple 911 calls about the attack that occurred on Thursday, Aug. 6.
- Surveillance video reviewed by investigators shows a person arriving in a gray Cadillac SUV, putting on a mask and a tactical vest, and stabbing the victim several times before fleeing.
- Police arrested 36-year-old Marcos Iriarte-Valdez at a Martinez home and booked him on suspicion of murder and related charges with bail set at more than $1 million.
- Authorities say Iriarte-Valdez had been on pretrial release for separate residential burglary cases, was briefly taken into custody for an alleged monitoring violation earlier in the week, and was ordered released the day before the killing.
- Investigators have not released a motive or said whether the suspect and victim knew each other, and the case is expected to prompt scrutiny of local pretrial release and home-detention monitoring practices.
