A former employee of a New Mexico company took his own life after shooting and killing two other employees and leaving four wounded at Emcore Fiber Optics in Albuquerque, according to police.
Earlier reports listed as many as 6 dead and 4 wounded.
Police received a 911 call at 9:26 a.m. reporting a shooting at Emcore and responded within minutes. Once inside the building, they said they found multiple people who had been shot. One person appeared to have died of a self-inflicted gunshot wound and police identified him as the shooter.
Police said the 37 year-old shooter's wife or girlfriend was one of the victims. They did not say whether she was among the deceased.
"We believe that the shooter is a spouse of an employee," Police Chief Ray Schultz said at a news conference."We are classifying this as a domestic violence workplace situation."
Initial reports of a second gunman led police to lock down the building and the surrounding residential neighborhoods. After a preliminary search, police said they do not believe there was a second gunman.
Police transported 85 employees to Manzano Mesa Multigenerational Center, a city-run community center, for interviews with detectives. Some employees had evacuated during the incident and had gone to a nearby military base, but later joined the rest of the employees for questioning.
The gunman's children were taken into protective custody by authorities. Police also said that the gunman was involved in a previous domestic violence incident, but it did not happen in Albuquerque, according to the Associate Press.
Police have secured the area and are in the process of investigating the incident.
