The son of Hell's Kitchen mobster Mickey Spillane died yesterday after falling out of the window of his sixth-floor apartment. Robert "Bobby" Spillane, an actor on shows like "Rescue Me" and "Law & Order," had allegedly leaned on the window to call out to his brother, who was on the street below. The screen collapsed and he fell to the ground. Spillane's uncle, Jim McManus, said, "Michael [Bobby's brother] said he'll never forget the thump when he hit the ground. He said, 'That will be in my mind forever.'"

Police don't suspect criminality in connection with the death, and did not find a suicide note in the apartment. Officers and medics responded to the call around 7:45 a.m. yesterday, but Spillane was pronounced dead at the scene. Family and friends mourned his death, saying he was a neighborhood fixture. His wife told the Post, "Words can't begin to express my pain and he'll live in our hearts forever."

Mickey Spillane was a powerful Irish-American mobster in the 60s and 70s, running the Westies gang and dubbed the "last Gentleman Gangster." He was gunned down in 1977, when Bobby was 12. Bobby wrote a column for the Daily News in 2002, describing what it was like growing up as the son of a gangster.
