PALM BEACH, Fla. (CNN) – Palm Beach County residents are being asked to help detectives solve a 21-year-old cold case.
The Palm Beach County Sheriff’s Office says it is trying to identify the 6th victim of a convicted serial killer.
It says Keith Hunter Jesperson, also known as “The Happy Face Killer,” killed at least 8 women in 6 states between 1990 and 1995.
Jesperson earned his nickname after writing letters or leaving messages at truck stops signed with a smiley face.
