The police have "barely budged on the investigation. I can't get any answer from them. It's been a very frustrating experience," he told the New York Daily News.
Scott Ruffalo, 39, died in his home Dec. 1, 2008 from a gunshot to the head, police said. The L.A. coroner ruled the shooting a homicide, stating the gun was fired at a 45-degree angle from above and in front of his head.
According to the Los Angeles Times, police questioned Shaha Mishaal Adham, 27 and her boyfriend Brian Scofield, later arresting Adham but releasing her after officials decided she was present but not responsible for the shooting. Adham insists Ruffalo shot himself accidentally during a game of Russian Roulette, said the NY Daily News.
Ronald Richards, a lawyer who represented Adham, claimed Ruffalo "played with guns in the past in front of numerous witnesses" and had a severe cocaine problem.
Scott Ruffalo was a top hairdresser who worked at salons in Santa Monica and Beverly Hills. He set up his own corporation, called Ruff Inc.
His brother Mark Ruffalo is a movie and television actor who has starred in "Where the Wilds Things Are," "Blindness," and the new Martin Scorsese film "Shutter Island."
The actor said he is still struggling to come to terms with his brother's death. "The loss of my brother was tragic and meaningless and violent," he told the New York Daily News. "You can lose faith in humanity and faith itself just trying to make meaning out of things that are so meaningless."
