Actor Johnny Lewis is dead at the age of 28, TMZ reports. Sons of Anarchy star Johnny Lewis went on a rage after what law enforcement believe was caused by drugs.

Police believe he was either high on either PCP or Methamphetamine when he allegedly killed an 81-year-old woman and himself when he fell off of a roof to his death. The incident happened in the Los Feliz area of Los Angeles, California. 

Authorities say 28-year-old Lewis is suspected of killing Catherine Davis, an elderly woman who he may have been renting a room from. Inside the house police discovered a dead cat beaten to death along with Catherine Davis.

Following the altercation Lewis was seen fighting with neighbors outside of the house before falling off of the roof. The neighbors said Lewis appeared to have superhuman strength at the time.

Lewis was an actor who most notably appeared on the FX series Sons of Anarchy as Kip “Half-Sack” Epps. He also once dated Katy Perry.
