Johnny Lewis, who starred in "The OC", and "Sons of Anarchy" for two seasons, was found dead.
After allegedly murdering his 81-year-old landlady and beating two men, Lewis was found in the driveway of the old woman's Los Angeles home.
He had allegedly tried to break in, and had to be held back by three people. Cops believe Lewis was on PCP or meth at the time because he fought off those people.
He even killed the old woman's cat and allegedly dismembered it.
Neighbors heard the woman's screams then saw Lewis attack two men outside with a block of wood, then climb onto the roof and fall to his death.
It turns out, he is the ex-boyfriend of pop superstar Katy Perry.
Katy and Johnny were an item from 2005 to 2006 before she shot to fame.
Katy was dating Johnny while he starred in the hit TV series The O.C playing alongside Mischa Barton as Dennis "Chili" Childress.
