A suspect is in custody after a police officer who was serving a warrant was fatally shot in Texas on Monday, authorities said.
Stapp said it was unclear if the wound was self-inflicted or inflicted by police gunfire.
According to police the suspect surrendered during the SWAT standoff.
San Marcos is about 30 miles south of Austin.
Copeland was a 19-year veteran of the force. Shortly after the officers arrive, the male suspect began firing at the officers, "much like in an ambush type of situation", Stapp said. "Officers around our state courageously serve and deserve our utmost honor and respect, especially during this time", he said.More news: Man held in terror plot to kill British prime minister
