For five years in the early 1990s, Keith Jesperson, a B.C.-born long-haul trucker, crisscrossed the western United States in his truck, killing women he met along the way. From 1990 to 1995 he killed at least eight women, ensuring his notoriety by sending anonymous confession letters to journalists and investigators which he often signed with a smiley face. Known widely as the “Happy Face Killer” for his unusual letter sign-off, Jesperson has since confessed to the serial killings and is serving four life sentences at the Oregon State Penitentiary. However, police are asking for help in identifying Jesperson’s final unknown victim.
Officials with Riverside County in California released a new sketch and DNA-renderings of a California woman whom Jesperson referred to as “Claudia” — although investigators are unsure if that’s her true name. Her body was found on Aug. 30, 1992, along a highway near the California-Arizona border, and is the only victim left to be properly identified.
“We hope to give this victim back her identity,” said Riverside Country District Attorney Mike Hestrin in a video statement. “We are hopeful someone hearing any of these details may remember anything that could help us reunite this woman with the family.”
In an effort to identify Claudia, cold case investigators interviewed Jesperson behind bars late last year. He told police that he first encountered her while at a brake-check area in Victorville, Calif., when she asked him for a ride to Los Angeles. Jesperson said he was heading to Arizona instead, and Claudia accepted his offer to ride with him. Jesperson told police they got into an argument about money while eating at a rest stop, which led to his decision to kill her.
He then said he drove to Blythe, a city on the Arizona-California border, and disposed of her body in some bushes once it was dark, before driving to Phoenix to complete his trucking job. Jesperson described Claudia as being in her 20s or 30s, medium build, weighing about 140 or 150 pounds, and had shaggy blonde hair. Her biological father, a Texan, is now deceased, and several half-siblings were identified but are not biological matches to the victim’s mother and had no idea Claudia existed.
Jesperson, now 68, has confessed to eight killings in his spree, spanning California, Nebraska, Wyoming, Oregon, Washington and Florida. Some of the women were drifters or sex workers, making identifying them more difficult. In 2022, the Calgary Police Service was credited with helping identify one of his victims — a woman by the name of Patricia Skiple of Colton, Ore., whose body was found on the side of a California highway in 1993. California investigators partnered with the DNA Doe Project, a U.S.-based non-profit organization that helps identify “Jane Does” and “John Does” using genetic genealogy services. This innovative method led to the identification of Skiple’s Canadian relatives who were identified during those searches. Jesperson was arrested in 1995 on suspicion of murder in Washington state, according to prison records, and eventually confessed to eight murders. Recent advances in forensic genetic genealogy have helped piece together their identities by connecting investigators to their living relatives.
