7 Disturbing Unsolved Mysteries In Wisconsin That Will Leave You Baffled

Amber Wilde was a 19 year old student at the University of Wisconsin-Green Bay when she went missing. Her car was discovered at a bar (with her keys and cell phone locked inside the trunk) near Lambeau Field but she has not been seen since 1998. Wilde was a few months pregnant when she disappeared on September 23, 1998. Earlier that day, she had been in a minor car accident. The father of her child has always been a suspect, and in late 2014, some rural property was searched. It is unclear what was searched for or found.

The year was 1987, and Blackstone went to a gas station in Lyndon Station (pictured above) to fill up a container of gas for her tractor and get gas for her car. It would be the last purchase she would make. Blackstone then returned home, where her husband discovered her car with the keys in it. There was no sign of Barbara or any note. About a month later, Blackstone's remains were found about 75 miles away. The case was re-opened in 2009, but there were no leads.
