(CNN) Police are looking for a New Mexico teenager who they say shot and killed a postal worker who tried to break up an argument between the teen and his mother. Xavier Zamora, 17, of Albuquerque, is wanted on a murder charge, accused of killing mail carrier Jose Hernandez on Monday afternoon. Hernandez was working his route in southwest Albuquerque when he saw Zamora in a dispute with Zamora's mother outside their house, and decided to help her de-escalate the fight, Albuquerque police say. Hernandez sprayed Mace on Zamora when the teen became aggressive toward him, police say, citing an interview with the mother. The teen then went into his house, came back outside with a gun and shot Hernandez in the abdomen before going back inside, according to police.
