Texas teen posts images of slain family, then kills self

ARANSAS PASS, Texas (AP) — A South Texas teen who said he killed his family and posted graphic images of their bodies on social media killed himself after officers found him at his home, authorities said Thursday.

The Aransas Pass police and San Patricio County sheriff's office say they started investigating after being alerted to the images on social media. They say the teen, identified as 15-year-old William Quince Colburn III, had also threatened to continue the violence at a school.

Law enforcement agencies late Wednesday night tracked the teen to a recreational vehicle park near Aransas Pass. Officers asked him to step outside of his motor home, but he refused. Officers then heard a single gunshot and the sound of a person falling to the ground, police said.

When officers entered the recreational vehicle they found the teen dead from a gunshot wound, along with the bodies of three other people and two dogs, police said.

San Patricio County Sheriff Oscar Rivera said the other three people also had been shot to death. He identified them as: William Colburn Jr., 63; Janna Colburn, 53; and Emma Colburn, 13.

Rivera said William Quince Colburn III and the three others found slain in the RV were related, but he did not yet know specifically how.

Police said that had it not been for the “speedy action” of the social media website and other teens within the group where the threat was made, “we might well have been working on an even more tragic event later this morning.”

“I’m glad that we were able to find him before something worse could have happened,” Rivera said.

Rivera said it was unclear what school the teen might have been threatening. He said the teen wasn't registered at any local schools and authorities believe he was homeschooled.

“I'm not sure which school he planned to attack but he certainly had the weapons and ammunition to do so," Rivera said.

He said the teen had at least two guns and a rifle.
