Wanted in connection with an incident that left four people dead at a North Hollywood restaurant April 3, two brothers were arrested April 20 at a residence in Kenmore.

According to the Los Angeles Police Department (LAPD), following his arrest, Nerses Arthur Galstyan was charged with four counts of murder and one count of mayhem. He was booked at the King County Correctional Facility in Seattle and is being held in lieu of a $4 million bail. Officials said Galstyan will be returned to Los Angeles early next week.

Reports do not make clear what connection his brother, Samuel Galstyan, may have had with the murders. Operated by the U.S. Marshals Service, the Pacific Southwest Regional Fugitive Task Force arrested the Galstyans with the help of the King County Sheriff’s Office. Both the LAPD and the Marshals Service stated the arrests were made without incident.

Again according to LAPD reports, on April 3, Nerses Galstyan was participating in a birthday memorial celebration with several others inside the Hot Spot Mediterranean Restaurant in North Hollywood.

The celebration was being held for an acquaintance that died in an accident a year earlier. According to investigators, Galstyan became involved in a heated argument with several men at the celebration. Also according to investigators, during the dispute, he became angry and fired a gun multiple times, ultimately killing four men.

Three of the men died at the scene, while another man died at a local hospital. Two others were wounded.

Police say surveillance video from the restaurant confirmed Nerses Galstyan was in the establishment and left following the shooting. The identification of Nerses Galstyan as a suspect in the murders came after what Los Angeles officials described as an exhaustive investigation conducted by L.A. robbery/homicide detectives with assistance from other law-enforcement agencies, including the FBI, the Bureau of Alcohol, Tobacco, Firearms and Explosives and the U.S. Secret Service.

According to information released by the U.S. Marshals Service, the Northwest Fugitive Task Force was asked to become involved with the search for Nerses Galstyan by a similar southwest unit headquartered in Los Angeles. A tip apparently led the Northwest Task Force to set up surveillance on a residential neighborhood in Kenmore.

The exact location was not released. Neither were any details about why the Galstyan brothers were in the home. The arrests came about 8:15 p.m. April 20.

Following a separate investigation, a federal grand jury indicted Nerses Galstyan on weapons violations. On April 9, a grand jury in a U.S. district court in California handed down an indictment naming Nerses Galstyan as a defendant and charging him with conspiracy for engaging in the business of dealing in firearms without a license and possession of a firearm with an obliterated serial number, namely two Spike’s Tactical .223 caliber semi-automatic rifles.

U.S. Marshal Joe Hawe of the Western District of Washington said the Marshals Service operates 86 separate fugitive task forces across the nation.

“The arrest of the Galstyan brothers in (Kenmore) is a prime example of the cooperation of these task forces and law-enforcement agencies throughout the country to bring fugitives to justice,” Hawe said.
