Kathleen Pehringer was 41 when she disappeared from her Riverton, Wyoming, home on April 17, 1989. She was last seen that morning by her 14-year-old daughter, Kelly, before leaving for school. Kelly returned later that day to find Kathleen gone; her purse and glasses were missing but her car remained parked outside. There were no signs of struggle and no note, which was uncharacteristic for her.

Investigators considered that Kathleen might have left voluntarily with someone she knew and may have intended to return. Suspicion fell on Donald Pack, a man she had recently been dating; Pack, a convicted rapist, stopped by the house on the day she vanished and behaved oddly, though he denied involvement and police were never able to definitively link him to the disappearance. Kathleen was declared legally deceased in 1998 and the Wyoming Division of Criminal Investigation still lists the case as open. Little else is known about what happened to her.

If anyone knew Kathleen’s routines, her relationships, or saw her or her car in Riverton around April 17, 1989, please come forward with any information.
