The Texas sheriff leading the investigation for a missing teenager from San Antonio announced on Wednesday a strong belief that the human remains discovered Tuesday afternoon near a firearm belong to Camila Mendoza Olmos, who disappeared on Christmas Eve.

The 19-year-old was last observed at 7 a.m. that morning, walking just two blocks from her residence.

“While it’s too soon to confirm the identity of the body or determine the cause of death, I personally have a strong feeling that it is her,” stated Bexar County Sheriff Javier Salazar in a Facebook Live update on Wednesday. “This is undoubtedly a tragic situation.”

He previously told reporters there were no signs of foul play and that the body appeared to have been there for several days. In his video Wednesday, he urged residents to check on their loved ones.

“Especially those that have been going through tough times,” he said.

Olmos had a history of suicidal ideation and depression, he said.

“It’s been a heartbreaking week,” Salazar added.

Olmos was one of three teens in the county reported missing in under a week.

Another, 14-year-old Sofia Peters-Cobos, was recovered safely. The third, 17-year-old Angelique Johnson, has been missing since Christmas Day.

A fourth missing person, a 55-year-old man named James Nunnery, also vanished on Christmas, according to the sheriff’s office. He was partway through a road trip to Mississippi and last spoke with a relative around 10 a.m., telling his mother he was 180 miles outside Dallas.
