EW has confirmed that 28-year-old actor Johnny Lewis — best known for playing Kip “Half-Sack” Epps on two seasons of Sons of Anarchy — was found dead outside a home in Los Feliz, Los Angeles on Wednesday. An LAPD rep says that Lewis is also a suspect in the murder of his landlord, 81-year-old Catherine Davis, whose body was found inside the residence. It appears that Lewis may have fallen from the building’s roof, though his cause of death has not yet been confirmed.

“The best we’re piecing together now is that it appears that some type of altercation occurred inside of the house resulting in the death of the woman, then this individual ran outside, had an altercation with a couple of neighbors, ran back into the house and by the time we got here, he had fallen or had somehow died on the driveway,” LAPD Commander Andrew Smith told a local ABC affiliate.

Lewis was written out of Sons of Anarchy in season 2. “Johnny wasn’t happy on the show. Creatively, he really wanted out of his contract. We had ongoing conversations, and we decided we’d find some noble way for him to go,” SOA creator Kurt Sutter said in 2009.

A rep for Sons of Anarchy has not yet responded to EW’s request for comment. UPDATE: SOA creator Kurt Sutter has tweeted about Lewis’s death, calling it “a tragic end for an extremely talented guy, who unfortunately had lost his way.”
