Sons of Anarchy actor Johnny Lewis fell to his death from a building in Los Angeles – moments after he allegedly beat his landlady, an 81-year-old woman, to death, authorities say.
Lewis, 28, who played Kip “Half-Sack” Epps on the FX show and who once dated Katy Perry, was found lying in a driveway in the Los Feliz neighborhood near Hollywood on Wednesday, while a woman identified as Catherine Davis was found dead of apparently blunt force trauma inside the building.
The upstairs part of the building had been ransacked. Police also found the body of a cat that had apparently been beaten.
“It’s a terrible tragedy as far as we’re concerned and were digging into the bottom of it,” LAPD spokesman Andrew Smith tells PEOPLE.
