It's been a rough week for fans of the TV series "Sons of Anarchy". First, fan favorite Opie, played by Ryan Hurst, was brutally killed off in Tuesday's episode, and now a former cast member is dead in real life.

28-year-old Johnny Lewis, who played Kip "Half Sack" Epps on the FX series, was found dead Wednesday outside a Los Feliz, CA house belonging to a woman whose dead body was found inside.

Police suspect Lewis of murdering 70-year-old Katherine Davis, the owner of the house. TMZ reports that Lewis may have been renting a room from Davis at the time of both of their deaths. Police later determined that Davis died of "blunt head trauma and strangulation".

According to sources, Davis was heard screaming inside the house and a group of men were involved in an altercation before one man, possibly Lewis, made his way to the roof before either jumping or falling to his death. 

Davis had only out of jail for a few days before the incident and had also spent some time in rehab. It is speculated that he may have been on PCP or crystal meth at the time of his death.
