Five Unsolved South Dakota Mysteries

Tina Marcotte was last seen on June 24, 1994. The last thing she did was call a friend to tell them she had gotten a flat tire on her car and was going to reach out to a coworker for help. The coworker that Tina was referring to was Tom Keuter. However, after the phone ended with her friend Tina was never seen or heard from again.
Tina's friend asked Tom what had happened but he denies even speaking to Tina. Funny thing is that Tom also stated he had car trouble the same night Tina did. Tom's wife was unable to confirm nor denied her husband's whereabouts as he did not come home until 3:30 AM that night.
After Tina disappeared, Tom was naturally questioned by police. But a day after Tom was questioned he was found dead. He had been run over by his own forklift at work.
