MISSION, Texas — An emotional press conference this morning as the Chief of the Mission Police Department Robert Dominguez confirmed the death of one of his officers. Cpl. Jose Luis Espericueta was killed last night as he exchanged gunfire with Juan Carlos Chapa Jr. Investigators say Chapa had an argument with his mother along a Mission, Texas highway and shot at her car. He then fled on foot. The mother, who has not been identified by police, flagged down officer Espericueta. Following a brief foot chase along the highway, the two had a gun battle at short range. That’s when both men were shot. The suspect died on the scene. Officer Espericueta died at the hospital.
