It all happened around 5:30 p.m. at the store on San Mateo near Zuni.  There was mayhem and confusion inside a southeast Albuquerque Wal Mart as employees and shoppers were sent fleeing by the sound of gunfire.

The victim in this case is 46-year old Joyce Cordova. She is in critical but stable condition at this time at UNM Hospital.

Albuquerque Police say Cordova had a long history of domestic violence with ex-husband Felix Vigil. A co-worker says Cordova was working in the deli was attacked by her ex-husband.

Vigil was shot to death by 72-year old Due Moore.  Police won't say how many shots were fired, but some witnesses tell News 13 they heard at least three shots.

Police say Moore had a concealed carry license and is a well-known volunteer with APD's cold case unit.

“It’s probably a very good thing he (Moore) was there,” says APD Sgt. Trish Hoffman. “Ms. Cordova may not be here today if it had not been for him.”

Police say there was a valid restraining order in place against the victim's ex-husband.

Police say Moore has been very cooperative and has not been charged with any crime.
