Actor Johnny Lewis, who formerly dated Katy Perry and had big roles on "Sons of Anarchy," and "The O.C.," was killed on Wednesday in a bizarre scene where LAPD found the actor, and his 81-year old female landlord dead, TMZ reports.

According to law enforcement sources, 28-year-old Lewis' body was found in a driveway Wednesday morning in Los Angeles' Los Feliz neighborhood, and the elderly woman who owned the home was found dead inside, the victim of a homicide.

According to multiple reports, neighbors heard the 81-year-old woman screaming and then saw a young man outside her home attack two other people with a piece of wood before he climbed onto the roof.

It's unclear if the young man, now identified as Lewis, jumped or fell from the roof to his death.

Lewis was renting a room from the homeowner, and is suspected of killing her.

Lewis was released from L.A. County Jail on September 21, and had several criminal cases filed against him at the time of his death, TMZ reports.

Law enforcement also says they believe Lewis was either on PCP or Meth at the time of the alleged murder. The two people who fought Lewis before he fell to his death from a roof told cops the actor exhibited "superhuman strength."

Lewis played 'Half-Sack' Epps on "Sons of Anarchy" for two seasons and also had one-off roles on "Criminal Minds," "Bones" and "CSI."

Lewis and Perry dated back in 2006 and attended numerous Hollywood events together.
