CONTRA COSTA CO.: SUSPECT IN BAY POINT KILLING SHOT ROOMMATE IN SELF-DEFENSE
A Bay Point man arrested last week on suspicion of fatally shooting his roommate was released from jail Friday after prosecutors decided the slaying was in self-defense, Contra Costa County Sheriff's spokesman Jimmy Lee said today.
Andrew Mahler, 33, was detained for questioning Tuesday shortly after sheriff's deputies found his roommate on the sidewalk in front of their residence at 44 Pensacola St. in the unincorporated community of Bay Point suffering from a gunshot wound, Lee said.
The roommate, 31-year-old William Lenox, was taken to John Muir Medical Center in Concord where he was pronounced dead. An autopsy found that he died form a gunshot wound to the abdomen, Lee said.
The shooting had reportedly occurred inside the roommates' residence, Lee said. Mahler had then allegedly gone over to a neighbor's house and either he or the neighbor called for help shortly after 5:30 p.m.
Deputies took Mahler to the station to question him and then officially arrested him at about 10:45 p.m., Lee said. He was booked into the Martinez Detention Facility on suspicion of murder, but when investigators presented the case to the Contra Costa County District Attorney's office Friday, prosecutors declined to file charges and Mahler was released Friday afternoon, Lee said.
