Two missing Tennessee girls are safe, and the man accused of abducting them and killing their mother and older sister is dead, authorities confirmed Thursday night.

Special operations teams following a tip located Adam Mayes with 12-year-old Alexandria and 8-year-old Kyliyah Bain in a wooded area behind a church in Alpine, Mississippi around 6:50 pm Thursday, FBI special agent Aaron Ford told reporters at a press conference. Ford said Mayes shot himself in the head with a semi-automatic pistol when ordered to surrender. He was later pronounced dead at a local hospital.

According to the Ford, the two girls, who were reported missing on April 27, appeared to be suffering from exposure, dehydration and poison ivy. The bodies of their mother, Jo Ann Bain, and 14-year-old sister Adrienne were found on the property where Mayes lived in Guntown, Mississippi last Friday.
