Hays County court documents reveal what led up to a shooting that killed San Marcos Police officer Ken Copeland Monday.

Copeland came in on his day off to help serve a warrant to 51-year-old veteran Stewart Mettz.

Neighbors identified Mettz as the man who then shot Copeland in an ambush-style attack.

Two warrants released by the Hays County District Attorney reveal Mettz was wanted for domestic violence charges.

Copeland and other officers showed up to Mettz's home on Valero Drive in the El Camino Real subdivision Monday to arrest him for family violence assault and an injury to the elderly charge.

On Tuesday, investigators cleared out of the neighborhood, but residents are still reeling from what happened there.

"I think it's the whole town right now. We're just in shock because losing an officer in the line of duty is not a good thing," a man who lives across from Mettz said.

The neighbor didn't want to use his name, but said Mettz never seemed violent. He described the alleged shooter as a quiet homeowner who spent a lot of time working on his yard--and made sure others did the same.

"He used to cut this yard right here and he used to get mad at them and say 'you need to cut your lawn.' And I'm like 'oh' and he tried to tell us something and I was like 'all right I'll cut it right now,' so he's always trying to get the yards, clean I guess," the neighbor said.

But inside that home on Valero Drive, a new arrest warrant details violent allegations from Mettz's wife and mother-in-law dating back to August. The women felt that following an incident after Thanksgiving, Mettz might kill them.

The women said they never reported the assaults before because they were afraid of him.

The San Marcos Police Department interviewed Mettz's wife and mother-in-law less than two weeks ago. They said Mettz allegedly dragged his mother-in-law from a bedroom by her neck and said he threatened her if she reported the incident.

Allegedly, that violence led to what unfolded outside Monday night in a deadly exchange of gunfire with officers.

Mettz was also injured in the incident, but is in fair condition at a hospital.

Neighbors can still see the fence that was torn down in Mettz's backyard by the SWAT team and say they're still in shock that a well-known member of the subdivision could do this.

"He told my roommate and I he was a veteran and stuff when I first moved over here like three years ago, so he's been here for a while," one neighbor said.

Hays County officials confirm there is a third warrant for Stewart Mettz's arrest that can't be released until he goes before a judge. That third charge may be related to Monday's shooting
