LAPD ID Suspect in NoHo Cafe Killings - Nerses Arthur Galstyan - North Hollywood Shooting. Los Angeles - Law enforcement authorities identified a suspect on Friday in a shooting at a North Hollywood restaurant that left four people dead, and they asked for the public's help finding him. Nerses Arthur Galstyan, 28, who has not been arrested, is believed to be the man who opened fire inside the Hot Spot Cafe, 11651 Riverside Drive, around 4:30 p.m. Saturday. According to Los Angeles police, Galstyan was at the restaurant attending a party in memory of an acquaintance who had died in an accident a year earlier. During that celebration, Galstyan became involved in a dispute with several men at the celebration and in anger fired multiple rounds, hitting and killing four of them, LAPD Chief Charlie Beck said. Three men died at the cafe, and a fourth died at a hospital. Two other people were injured, but survived. The dead men were identified by Los Angeles police as Harut Baburyan, 28, Sarkis Karadjian, 26, Vardan Tofalyan, 31, and Hayk Yegnanyan, 25. Police said Galstyan was seen on surveillance video inside the restaurant. Police initially said the victims appeared to have been targeted and that the shooting may have been related to Armenian gangs, but they said Friday the shooting was apparently just a dispute that erupted at a party. In February, Galstyan was charged in a federal indictment with conspiracy, engaging in the business of dealing in firearms without a license and possession of a firearm with an obliterated serial number. According to the indictment, Galstyan allegedly met with a confidential informant on Sept. 2 and sold two .223-caliber semiautomatic rifles with obliterated serial numbers, along with two high-capacity magazines, for $3,600. Galstyan also allegedly told the informant that he could sell HK rifles with 8-inch barrels for $3,000 each, and that he routinely had AK weapons for sale, according to the indictment. Galstyan remained at large and police said he should be considered armed and very dangerous.
