Antioch police said officers arrived to find paramedics trying to revive the man, but he died at the scene.

Detectives believe the man lost consciousness during a physical fight with a roommate. Police detained a 47-year-old resident of the home for questioning, but made no arrest.

Lt. Bill Whitaker said investigators are awaiting autopsy results and a review by the Contra Costa County District Attorney’s Office before deciding whether charges are warranted, according to the East Bay Times. Whitaker told reporters the evidence so far points toward self-defense, the Times reported.

Investigators said the altercation involved no weapons.

Crime scene investigators and Antioch’s Violent Crimes Unit are handling what is now the city’s third homicide investigation of the year. One of Antioch’s earlier homicide cases was also ruled justified because of self-defense, according to police.

Antioch police recorded two homicide investigations at the same time in 2025.
