Law enforcement officials in Texas are still trying to determine the identity and possible motive of the individual who shot and killed a sheriff’s deputy near Houston late Friday night in what has been described as an “ambush” at a local gas station.

Deputy Darren Goforth, 47, was pumping gas about 8:30 p.m. Friday when a man approached him from behind and fired multiple shots, Harris County Sheriff’s Office spokesman Ryan Sullivan told the Associated Press.

Following a frantic search overnight by police, Reuters cited comments made by Houston Police Officer John Moore to report that the still unnamed suspect “was taken into custody early Saturday” at his mother’s house not far from the gas station where the shooting took place.

“She called to tell them he was there,” Moore told Reuters. “There is a suspect in custody believed to be the shooter.”

According to Moore, the suspect was being held in the Harris County jail.

Meanwhile, other outlets as of late Saturday morning (EDT) were still reporting the individual in custody may only be a “person of interest” and that the investigation and search was ongoing.
