Donna Krnak, 52, vanished on July 2, 1998, from Helenville, Wisconsin, along with her husband Allen and their son Thomas. The family were said to be driving to a cabin in Coloma for the Fourth of July weekend; their older son Derek Anderson (born Andrew Krnak) reported them missing several days later.

A week after they disappeared the family’s truck was found abandoned near Reedsburg with no fingerprints or luggage, and the family’s dog was also missing. In 1999 Allen’s remains were found in North Carolina along with Donna’s wedding ring and the dog’s remains. Investigators suspect foul play and that Donna and Thomas were also murdered, but neither has been found and their exact fate remains unknown.

Anyone who saw the Krnaks, their truck, or their dog around July 2, 1998, or who has information about Donna and Thomas, is asked to come forward.
