A Texas police officer was his department’s first officer killed in the line of duty in more than 40 years

Cpl. Jose “Speedy” Espericueta, an officer in the city of Mission near the Mexico border, was responding to an assistance call from another officer Thursday night, police Chief Robert Dominguez said during a press conference Friday. A woman had waved down police, saying her son had shot at her car, he said.

When Espericueta arrived, he saw the son, later identified as Juan Carlos Chapa Jr., walking and attempted to make contact with him. Chapa began to run, then turned around and started firing at Espericueta, hitting him, police said.
