Mary Ann Tautkus, also known as Mary Ann Havens, vanished from Eben Junction, Michigan, with May 1, 2009 listed as her last-contact date. Her husband reported he drove her to St. Ignace in early May so she could meet an unidentified friend and travel to the Detroit area, but Mary never checked in with family or authorities after that trip. She was 64, about five feet four inches tall, with short gray hair, blue eyes, and wore prescription eyeglasses; she may have been wearing a light-blue pullover and matching pants when last seen.

The case is complicated by a nearly four-month gap before she was reported missing on August 31, 2009, and by conflicting accounts that place her away from Eben Junction as early as January 2009. The Michigan State Police Munising Post opened the investigation and formed a task force in October 2009; investigators later said they suspected foul play, but no public details explain that conclusion, and no confirmed sightings, belongings or remains have been reported.

If anyone knew Mary, the friend she was supposed to meet, or saw her in St. Ignace or along the route to Detroit that spring, please share what might help fill the gaps in her timeline.
