Kathleen Pehringer, a 41-year-old woman, disappeared from her home in Riverton, Wyoming, on April 17, 1989. She was last seen by her 14-year-old daughter, Kelly, before leaving for school that morning. When Kelly returned home later that day, she found Kathleen gone, with her purse and glasses missing, but her car still parked outside. There were no signs of struggle, and Kathleen had left no note, which was uncharacteristic for her.
Investigators believe Kathleen may have left voluntarily with someone she knew, possibly intending to return shortly. Suspicion quickly fell on Donald Pack, a man Kathleen had recently been dating. Pack, a convicted rapist, had spent time in prison and was known to have targeted women who matched Kathleen’s profile. On the day of her disappearance, Pack stopped by the house, asking for Kathleen and behaving oddly, though he denied any involvement in her disappearance. Despite this, police were never able to definitively link him to the case.
Kathleen was declared legally deceased in 1998, but her case remains unsolved. Her daughter Kelly has spent years seeking answers, and the case continues to be an open investigation under the Wyoming Division of Criminal Investigation. Authorities believe Kathleen may have been the victim of foul play, but no conclusive evidence has surfaced regarding her fate.Last Seen: Apr 17, 1989
