Veronica Voni Safranski, 40, vanished after a Halloween party at Mick’s Bar in Warren, Minnesota, on October 26, 1996. She was last seen around 12:30 a.m. when a friend lost track of her after returning from the restroom. Witnesses said Safranski left with a man named Kevin Skjerven in his black Dodge Power Wagon pickup truck.

In the weeks after her disappearance a belt believed to be part of Safranski’s costume was found along a rural road; no other significant physical evidence has turned up. Investigators have long treated Skjerven as a person of interest because he admitted leaving the bar with Safranski and because of prior sexual assault convictions, but he has never been charged and says he does not know what happened to her.

Safranski’s four children continue to seek closure and authorities are still asking anyone with information to come forward.
