Donna Jean Michalenko, 38, vanished from rural McLean County, North Dakota, in November 1968.

Reportedly Donna spent an afternoon with a male friend, they were seen leaving a Kief bar together around midnight, and the friend later said he dropped her off at the Butte home where her ex-husband and three children lived. She was not heard from again and was reported missing by her daughter on December 27, 1968.

Does anyone remember Donna, the Kief or Butte area in November 1968, or the friend who reported dropping her off?
