Missing Since: 2015-10-11 Location: Schofield, Wisconsin
Mackenzie disappeared from Schofield, Wisconsin on October 11, 2015; she was last seen at her home, and vanished during the night of October 10-11. She was a freshman at Mosinee High School at the time of her disappearance. Authorities believe she left of her own accord; she had run away twice before and each time was found with her friends. Since her disappearance, her family and friends haven’t heard anything from her. Although Mackenzie’s parents wouldn’t allow her to have a cellular phone and they monitored her internet usage, after her disappearance, they discovered she’d been talking online with strange men and using apps to hide her activity from her family. Her case remains unsolved.
