Authorities are trying to identify remains found near a stream bed in northwest Missouri.

The remains were found Sunday in Caldwell County after authorities received a tip from a resident.

Investigators are trying to determine if the remains are those of 50-year-old Carol Thompson of Lathrop, who disappeared a year ago.

Thompson disappeared from a home along Missouri Highway 116, about eight miles east of Lathrop.

The remains were found about a mile from that home.

Authorities say Thompson had no history of disappearing or mental health issues. She left behind her car, medication and purse when she disappeared.

The Missouri State Highway Patrol’s drug and crime unit is helping with the investigation. An autopsy is being performed to identify the remains.
