KRQE

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, or what caliber weapon he used.

Schultz said the gunman was a former employee, but did not release his name.
