Johnny Lewis, an actor who most notably appeared on the FX series Sons of Anarchy, died on Wednesday in Los Angeles after he either fell or jumped off a roof to his death at a home where an 81-year-old woman was found dead inside.

Authorities say 28-year-old Lewis is suspected of killing the woman, who owned the house. He may have been renting a room from the homeowner, identified as Catherine Davis by the Los Angeles County Coroner's Office. [UPDATE 3:45 P.M. PT: The LAPD and coroner have announced that Davis died of "blunt-force trauma and manual strangulation."]

Officers had been sent to the residence after receiving reports of a woman screaming.
