CARY, N.C. — Cary Police issued an all-points-bulletin Monday, asking authorities in nearby states to be on the lookout for Arnulfo Cobos.

Police obtained a warrant charging Cobos with murder in the death of his girlfriend, Maria Teresa Herrera-Diaz.

Diaz' roommates found her body Saturday morning at their home at 102 Dunhagen Place. The cause of her death has not been released.

Police ruled the case a homicide after they received preliminary autopsy results Sunday.

Investigators believe Cobos left the home he shared with Herrera-Diaz and some other people between 4:15 a.m. and 5:15 a.m. Saturday, driving a stolen silver 2004 Saturn L-300, with North Carolina license plate number XWT-5469. They has said Saturday night that they were looking for the car and Cobos.

Police described Cobos as an Hispanic man, about 50 years old, standing 5 feet 6 to 7 inches tall and weighing 200 pounds. In a picture distributed by police, he has a mustache, and police said he also has a goatee.

Police described Cobos as Hererra-Diaz' common-law husband, though North Carolina doesn't provide for that relationship legally.

A corporate spokeswoman for Herrera-Diaz's employer said, “We were shocked to learn this. She was an excellent employee. She never had any problems, always had a smile on her face and worked very hard.”

Anyone with information related to this incident should call the Cary Police Department Watch Commander at 919-469-4016.
