ANTIOCH — A 38-year-old Antioch man was arrested last week on suspicion of shooting his roommate during an argument, police said.

Agustin Chavez is being charged with assault with a deadly weapon, possession of a firearm with narcotics, and a pair of controlled substance charges, all stemming from a March 12 incident, when police say he pulled out a gun and shot his roommate in the chest during an argument.

The victim, a 39-year-old Antioch man, is in stable condition but still hospitalized, said Antioch police Sgt. Tom Fuhrmann, who wouldn’t discuss the argument or provide further details.

When asked whether police believed either Chavez or his roommate were selling drugs from their residence, Fuhrmann said, “The charges would lead you to believe they’re selling drugs” but refused to elaborate. He said police are still investigating the incident.

The shooting occurred on the 2800 block of Carob Street in Antioch.

Police encourage anyone with information on this case to call Detective McManus at 925-779-6940.
