The L.A. County Coroner's Office has ruled the shooting death of Mark Ruffalo's brother as a homicide, according to the AP.
Beverly Hills police arrested -- and later released -- Shaha Mishaal Adham, whose lawyer had claimed Scott Ruffalo was killed playing Russian roulette.
Ronald Richards, an attorney who represents Adham, tells TMZ, "I have not been informed by police that my client is again at all a suspect."
There was also another person, Kristian Muradaz, who was arrested and released. Police have yet to release a motive.
Ruffalo was shot on December 1 and died a week later.
