Bernalillo County authorities say they won't seek charges against an Albuquerque police SWAT team officer in a 2011 fatal shooting.
County District Attorney Kari Brandenburg and Chief Deputy District Attorney Troy Davis wrote a letter of findings Monday to Albuquerque Police Chief Ray Schultz.
Brandenburg and Davis say they found no probable cause to believe that officer Jim Perdue acted unlawfully when he shot robbery suspect Michael Marquez on Aug. 30, 2011.
Police say Perdue shot Marquez after a short standoff in a field near an Albuquerque apartment complex.
They say Marquez refused to drop what turned out to be a loaded AK-47 assault-style rifle, which was in a bag during the encounter.
Albuquerque police detectives had been following Marquez, who was suspected in three armed robberies.
