Isaias de Jesus Valencia, 39, has been formally charged with fatally shooting a Pomona police officer and seriously wounding another on Tuesday with capital murder and multiple counts of attempted murder.
Valencia was booked to appear in a Pomona court for the first time, but the hearing has proceeded to May 1.
According to the Los Angeles County District Attorney’s Office, the charges against him include special condition allegations of murder of a peace officer and murder to avoid or prevent a lawful arrest.
Prosecutors said Valencia is likewise facing one count each of fleeing a pursuing peace officer’s vehicle and possession of a firearm by a felon. If indicted as charged, he faces the death penalty or life in prison without the likelihood of parole.
The DA’s office has not yet decided whether to seek capital punishment in the case.
Valencia was arrested on Saturday after a 15-hour standoff. He led the police on a short chase on Friday night before barricading himself inside his apartment police said. Valencia then shot multiple times which led to the death of 30-year-old Officer Gregg Casillas and injuring Officer Alex Nguyen, who is presently recovering, investigators said.
Valencia was committed to state prison in 2014 with a two-year sentence for possession of a firearm and ammunition, discharging a firearm in a school zone and destruction of prison property, according to the California Department of Corrections.
The victim Casillas was being trained at the time of the barricade and had been on the job for only half a year.
Around twelve officers and deputies accompanied Casillas family to Valencia’s hearing on Tuesday. The fallen officer leaves his wife and two kids, with the youngest being 5 months old.
No plea was entered by Valencia and his lawyer said she has “so many documents” that still need review.
