The Erath County Sheriff's Office is trying to figure out who shot Jeffrey Vegas Sewalt at his residence off Pigeon Road Friday afternoon.
Sheriff Tommy Bryant said his office received a call about 2:30 p.m. Friday from a woman claiming to be Sewalt’s girlfriend who found him dead at his home.
Sewalt, 56, who has ties to Brownwood, was found lying in an enclosed porch with a gunshot wound to the head, Bryant said.
"We are treating this like a murder investigation," Bryant said. "It does not appear to be a suicide."
Bryant said no gun was found at the scene.
The Texas Rangers have been called in to assist in the investigation and no suspects have been identified.
