ALBUQUERQUE, N.M. – A gunman opened fire at an Albuquerque fiber optics manufacturer on Monday, killing five people and wounding four others before turning the gun on himself in what police said was a domestic violence dispute.

The shooting at Emcore Corp. appeared to involve the 37-year-old gunman's ex-wife or girlfriend, police Chief Ray Schultz said. It was not immediately clear whether she was among the dead. Schultz said the gunman was a former employee.

Chaos unfolded as the gunman opened fire, sending employees fleeing for cover as police locked down the entire neighborhood. Police said 85 employees were later taken to a community center for interviews with detectives.

Six victims were taken to University of New Mexico Hospital, spokesman Billy Sparks said. One was dead on arrival, one died in the operating room and one was still in surgery but expected to be transferred to intensive care soon.
