Early Monday morning, a musician from Iran reportedly shot and killed two members of an Iranian-formed rock band before killing himself at an East Williamsburg, Brooklyn apartment. Another Iranian musician was also killed in the attack.

According to the New York Post, the musician used a semi-automatic rifle in the attack, which started just after midnight on Monday morning. The gunman wounded one person outside before walking inside the apartment, where he killed two people on the second floor and one person—who was reportedly still in bed—on the third floor. Two people hid in the apartment's first floor bathroom; they were both unharmed. The shooter then climbed to the building's roof and shot himself in the head, according to the NYPD.

The New York Times spoke to neighbors who said the shooter and his victims were in a band named the Yellow Dogs. The gunman had recently been kicked out of the group, according to reports, though it's not yet clear why.

All of the band's members were from Iran and were featured in an award-winning documentary, No One Knows About Persian Cats, about underground rock music in Tehran. Shortly after the documentary was released in 2009, the band members left for the United States, where they were granted asylum in 2010.

UPDATE: The alleged shooter has been identified as Raefe Ahkbar Ali Akbar Mohammadi Rafie. According to the Wall Street Journal, Ahkbar Rafie was kicked out of the band sometime in the past year for selling the group's equipment. The victims were also identified:

Soroush Farazmand, 27, a guitarist in the band

Ali Eskandarian, 35, the band's singer

Arash Farazmand, the band's drummer

Sasan Sadeghpourosko, 22, was shot twice in his right arm and is in stable condition.

UPDATE 2: Rafie was not a member of the Yellow Dogs, according to the band's manager, who also said only two band members were killed in the shooting. From the manager's statement, via Pitchfork:

The shooter was not a former member of the band The Yellow Dogs, he was in another band from Iran and the two groups were acquaintances in the past. A personal conflict between the guys resulted in the dissolution of their relationship in 2012. The shooting resulted in the death of two of the members of the Yellow Dogs, Sourosh Farazmand (guitarist) and Arash Farazmand (drummer), along with a friend of theirs, fellow musician and author Ali Eskandarian. The shooter died from a self inflicted bullet wound on site.

UPDATE 3: The Wall Street Journal has a revised timeline of the shooting.
