Johnny Lewis Was Not On Drugs Before Death

A Sons of Anarchy television star who reportedly murdered his landlady before falling to his death, had no drugs in his system, according to an autopsy.

Toxicology results on Johnny Lewis found no traces of cocaine, alcohol, marijuana or any other types of drugs in his system. Officials checked for anti-psychotic drugs as well as psychedelic drugs.

The 29-year-old was found dead in September in the driveway of a Los Angeles home. Police later found his landlady's body inside the property.

Officials believe Lewis fell to his death while trying to escape after killing 81-year-old Catherine Davis.

Earlier this year he had enrolled in a drug and alcohol psychiatric treatment programme, after a spate of run-ins with police.

Lewis, whose full name was Jonathan Kendrick Lewis, had a career spanning more than a decade, mostly performing minor roles.

He played Ricky in the 2007 movie Aliens vs Predator - Requiem, and Scotty in the 2010 movie The Runaways, starring Kristen Stewart.

He also had a relationship with the singer Katy Perry in 2006.
