"Authorities Seek Help Identifying Final Victim of 'Happy Face Killer'"

Riverside County officials are seeking help to identify the last unidentified victim of the "Happy Face Killer," who was murdered in 1992. Known as "Claudia" by the killer, she was described as having shaggy, wild blonde hair and was about 20 to 30 years old at the time. Recent advances in DNA technology and tips from the public are hoped to help discover her name. The killer, Keith Jesperson, claimed to have killed women in five states and was given the nickname "Happy Face Killer" due to the smiley faces he drew on a letter he sent to a newspaper bragging about his crimes.
