Did Ruffalo brother die in Russian roulette game?

Mark Ruffalo's brother Scott was killed after playing a deadly game of Russian roulette, according to the prime suspect in the case.
Scott was found outside his Beverley Hills home with a gunshot wound to the head during the weekend. He was taken off life support on Monday.

Shaha Adham turned herself in to the authorities after police issued a warrant . She was seen leaving Scott's house on the night of the incident. After viewing the surveillance footage, police have identified another man Brian Scofield as a "person of interest" in the case.
Adham has told police Scott shot himself while playing a game of Russian roulette. She also alleges that the hairdresser was under the influence of controlled substances at the time.
Her lawyer Ronald Richards told the New York Post, "We expect the coroner's report to show the shooting was a result of the victim's chronic playing of Russian roulette and his dangerous playing with firearms while under the use of controlled substances.
"My client was a good friend of the victim and is very sad for the loss of his family. However, she played no role whatsoever in his accidental death."
Zodiac actor Mark recently thanked his fans for their support. A statement read, "Mark Ruffalo and his family deeply appreciate the outpouring of prayers and support during this most difficult time of the passing of Scott Ruffalo, beloved son, brother and husband."
