An actor whose character died a violent death on TV drama Sons Of Anarchy plunged to his death in a driveway after apparently killing his landlady and attacking neighbours near Hollywood.
Johnny Lewis, who played Kip "Half-Sack" Epps in the FX show, is the only suspect in the death of 81-year-old Catherine Davis, according to Los Angeles police.
Authorities found them dead on Wednesday morning after neighbours reported a woman screaming inside the home, Cmdr Andrew Smith said.
Lewis' death ended in a turbulent nearly 10-month span during which he was repeatedly arrested and officials expressed concerns about his mental health and the danger he posed to others.
The home where Ms Davis was found had been ransacked, glass was shattered and a dead cat was found.
Neighbours said a man had jumped a fence and assaulted a painter and homeowner next door.
The body of Lewis, 28, was found in the driveway. He could have jumped or fallen from the roof, garage or balcony, or tumbled down stairs from a patio area, Cmdr Smith said. It appears Ms Davis had been beaten, he added.
Because of the circumstances, investigators were checking whether Lewis was on drugs or had mental health issues, Cmdr Smith said.
The deaths came about four months after a probation officer expressed grave concern about Lewis' mental health. The report was prepared in a case in which Lewis was accused of attempting to break into the home of a woman in Santa Monica, California, and it described him as a transient. That case came about six weeks after Lewis hit two men over the head with a bottle during a fight.
Lewis' career spanned more than a decade, mainly in small roles. He played Ricky in the 2007 movie AVPR: Aliens vs Predator - Requiem and was Dennis "Chili" Childress for two seasons on TV's The OC. He also appeared in episodes of popular US television shows including Boston Public, Judging Amy, Malcolm In The Middle and Drake & Josh. He was on Sons of Anarchy in 2008 and 2009 before his character was killed off.
