An Army veteran from O’Fallon, Missouri, who disappeared earlier this month was found deceased in the mountains of Wyoming on Thursday, Oct. 17, according to his family.

Caleb Rios, 26, was last seen Oct. 1 in St. Charles County, Missouri, police said.

Caleb’s father, Eric Rios, was not worried at first, but then they saw some red flags, according to KSDK.

They found out that Caleb was searching for suicide articles online. The night he left, Caleb reportedly left the back door unlocked and left with cash. He also took a handgun with him.

Eric told KSDK that two of Caleb’s friends just committed suicide in the last few months.

“Thank you for sharing the story and helping us try and find him,” said Eric Rios.
