IDAHO FALLS, Idaho (AP) — A former Idaho State University professor wants to solve a 1970s east Idaho death mystery and is raising money to find additional clues.

The Idaho Falls Post Register reports Amy Michael is raising money for DNA testing on cut-up human remains found in Buffalo Cave, also known as the Civil Defense Cave, near the Montana border.

A family searching for arrowheads found a male torso in 1979.

The arms and legs were found 12 years later. The head has not been located.

Clark County chief deputy John Clements says cuts on the body parts indicate someone dismembered the man with a saw.

Michael hopes new forensic DNA testing can help identify the dead man.

Michael said she needs $2,300 to perform the tests. She had raised $470 as of Wednesday.
