GUADALUPE COUNTY, Texas (KXAN) — Human remains found near Seguin last Monday have been identified as a teenager who’s been missing since late October. His death is being considered a homicide.

The Guadalupe County Sheriff’s Office said it was alerted Monday by Texas Rangers that the body belonged to Benjamin “Tank” Loera, 16, from Vanderbilt, Texas.

The Jackson County Sheriff’s Office and Texas Rangers have been investigating Loera’s disappearance since Oct. 26. His death was ruled a homicide, according to Guadalupe County.

Three people are currently in custody in Jackson County. Their charges relate to Loera’s disappearance, Guadalupe County said. More charges are expected in the coming days.
