A juvenile male who allegedly posted pictures of his dead relatives and threatened a school in the Aransas Pass area killed himself as officers approached the crime scene, police said.
The Aransas Pass Police Department and the San Patricio County Sheriff’s Office said they discovered the 15-year-old boy’s body along with the bodies of three other people and two dogs in a trailer at the Aransas RV Park on Wednesday evening.
Authorities said they were tracking down the boy after he posted the graphic images of three people who he identified as his family members on social media.
It is unclear how they died, but SPCSO Sheriff Oscar Rivera said the boy, identified as William Quince Colburn III, claimed he killed them.
APPD said he also “threatened to continue violence at an area school.”
Officers with APPD, Ingleside Police Department and SPCSO tracked him to an RV where he lived.
When they asked him to exit the RV, he refused. Police said they then heard a single gunshot and a thud of him falling to the floor.
“Entry was made into the RV and (officers) immediately discovered the graphic scene shared over social media,” the APPD said in a news release.
Rivera identified the victims as William Colburn Jr., 63, Janna Colburn, 53, and Emma Colburn, 13.
The murder-suicide is still under investigation, and APPD is working with the Aransas Pass Independent School District and the Ingleside Independent School District.
There is no further threat to students or staff, police said.
