The Los Angeles County Coroner's Office has ruled the death of Mark Ruffalo's 39-year-old brother, Scott, a homicide.
Ruffalo died in the hospital Dec. 8, a week after being discovered in his Beverly Hills apartment with a gunshot wound to the head. Coroner's spokesman Craig Harvey said Wednesday that their investigation has determined that someone else shot him.
Police arrested a suspect, 26-year-old Shaha Mishaal Adha, on Dec. 9, but she was released and cleared of playing a role in Scott's death less than two days after turning herself in for question.
Adha's attorney, Ronald Richards, made the media rounds soon after, describing the incident as a case of Russian roulette gone awry. Scott Ruffalo was a habitual drug user, Richards said, and was "under the use of controlled substances" the night he was mortally wounded.
No other suspects have been named publicly.
According to TMZ.com, a 29-year-old man was also arrested an booked on suspicion of attempted murder in connection with the crime a day after Scott was hospitalized, but he was released less than three days later without being charged.
