Updated on: December 31, 2025 / 4:12 PM EST / CBS News A body found in Texas on Tuesday has been identified as Camila Mendoza Olmos, a 19-year-old girl who went missing shortly after leaving her San Antonio home on Dec. 24, the Bexar County Sheriff's Office confirmed Wednesday. The Bexar County medical examiner determined the cause of the death was a gunshot wound to the head and ruled that Mendoza Olmos died by suicide. Sheriff Javier Salazar had said on Tuesday that the body was wearing clothing that was "very similar" to what his office believes Mendoza Olmos was wearing when she was last seen. Salazar said the body was found around 4:45 p.m. local time in a field about 100 yards from Mendoza Olmos' home. The area had previously been checked, but it was searched again because of concerns over tall grass, Salazar said. He said the body was found by combined teams from the sheriff's office and the FBI.  Foul play is not suspected and there were indications of self-harm, Salazar said, adding Mendoza Olmos had been "going through a tough time." Salazar said a firearm was found near the body and that investigators had also been looking for a family member's firearm that had gone missing.  Mendoza Olmos was last seen the morning of Christmas Eve, when a neighbor's doorbell camera appears to have captured her standing next to her car just before 7 a.m., according to the Bexar County Sheriff's Office.
