(Columbus) A Columbus woman has been federally charged in a murder-for-hire plot. Kelly Harper was taken into custody Friday for reportedly using the dark web in attempts to hire a hitman and pay them in bitcoin currency to kill an unnamed Sun Prairie man from late October through December. According to prosecutors, Harper had a bitcoin wallet with a value of $5,633. She also allegedly gave details of the person she wanted killed including physical descriptions, his vehicle and where he worked. A group of journalists found the posting and turned over the evidence to authorities. The 37-year-old is currently being held at the Dane County jail.
