Tina Antero Lawrence, 47

Tina Antero Lawrence, a 47-year-old Latina, was shot and killed Sunday, Oct. 11, in the 3800 block of West 180th Place in Torrance, according to Los Angeles County coroner’s records.

About 12:20 a.m., neighbors called police after hearing an argument and gunshots, said Sgt. Paul Kranke with the Torrance Police Department.

Investigators found that Lawrence and her 32-year-old live-in boyfriend had gotten into an argument, Kranke said. The man then pulled out a gun and shot Lawrence, then shot himself.

Lawrence was pronounced dead at the scene at 12:35 a.m.

Investigators determined that the boyfriend was mentally ill, hadn’t been taking his medication and accused his girlfriend of having an affair.

The weapon was registered to Lawrence, Kranke said.
