ROCK SPRINGS, Wyo. — The family of a Sedalia, Missouri, man who disappeared more than 40 years ago finally has at least one answer.

The Rock Springs, Wyoming, Sheriff’s Office announced Wednesday that human remains found in 1982, are those of Jack Clawson.

Investigators said new forensic technology and advancements allowed them to put an identity to the remains.

The sheriff’s office said Clawson visited family members in Fremont, California, in July 1981. He left to return home to Sedalia, but no one heard from him again.
