As details about Monday's tragic triple-murder-suicide in East Williamsburg continue to unfold, one survivor of the rampage has come forward with his side of the story.

Pooya Hosseini, a founding member of Iranian band Free Keys and friend of slain Yellow Dogs musicians Soroush Farazmand and Arash Farazmand, was at the 318 Maujer Street brownstone on Monday when gunman Ali Akbar Mohammadi Rafie allegedly shot through an upstairs window and broke in. Hosseini, who had been friends with Rafie in Tehran and played music with him until Rafie was kicked out of the Free Keys last year, told the Times he initially believed the gunman was a man who had previously rented a room in the house. He heard shots and the sound of someone dying; he couldn't remember the number for the American police. "That was the worst moment in my life,” he told the Times. “I was just sure they just wanted to kill this group of Persians."

Eventually Rafie made it to Hosseini's room, and Hosseini begged him to spare his life. "He asked me, ‘What happened to us?'" Hosseini said. "I said, ‘Don’t kill me! Don’t kill me! Let me talk and then do it.'" Hosseini managed to tackle Rafie, who ran to the roof and fatally shot himself. "I really wish he didn’t kill himself,” Hosseini said. “When somebody kills himself, he makes it easy for himself. I didn’t want it to be easy. I wish he was in jail for all of his life."

Though investigators don't know exactly what drove Rafie to his alleged rampage, friends and acquaintances say the 28-year-old had had a difficult time in his few years in Brooklyn. "Some Iranians who come to New York have these high hopes and dreams of what it’s like to live here,” Melody Safavi, an Iranian singer, told NY Mag. “They expect things that aren’t really realistic. When they come here, they become disappointed. Some of them get depressed, anxious, and isolated. I think that’s what happened to [Rafie].”

After Rafie was thrown out of Free Keys, he reportedly became even more withdrawn, and recently friends say he was prone to paranoid outbursts about Freemasons and blowing up government buildings. "He said, ‘You had a plan to bring me here and put me in a band, but you did it just to bring me here and fix me with a group of Freemasonry," Hosseini recalled Rafie saying during Monday's attack.

In addition to allegedly slaying the two Yellow Dogs members, police say Rafie also shot and killed Iranian musician and writer Ali Eskandarian, who was friends with the other victims. The remaining Yellow Dogs members, along with Hosseini, put out a statement on Wednesday vowing to continue playing music, despite facing "the greatest sorrow we’ve ever experienced."
