Keith Jesperson's killing spree began in 1990, when Melissa was just 10 years old. In the next five years, he would kill eight women in five states. He even sent an anonymous letter to a local newspaper describing his savage murders in detail. The letters were signed with a smiley face drawing, earning him the nickname "The Happy Face Killer."
Jesperson's victims were strangers, which made him difficult to track down. One of the women was a young mother of 2-year-old twins. After killing her, Jesperson strapped her body to the bottom of a truck and dragged it for miles.
