The affidavit said Copeland approached Mettz’ door around 2:23 p.m. with several other officers.

Mettz opened the door after officers knocked, and began shooting at them, the affidavit said.

Police returned fire and pulled Copeland out of harm’s way after he was shot. A fellow officer rushed him to Central Texas Medical Center in San Marcos, but Copeland died from his injures.

The document said Mettz told investigators he shot Copeland two times in his chest, and that he was hit in his left side by an officer who returned fire.

“It was clear that Mettz knew the person he shot was a police officer,” the affidavit said.
