After nearly 34 years, authorities have restored a name to the final known victim of the “Happy Face Killer.”
Lydia Jane Wade McWhorter was 26 when her body was found on Aug. 30, 1992, along Highway 95 near Blythe, Calif. For decades, investigators knew her only as “Claudia,” the name convicted serial killer Keith Hunter Jesperson used when recounting her death.
On Aug. 27, the Riverside County District Attorney’s Office announced that investigators had formally identified the woman as McWhorter.

In a news release, the district attorney’s office said, “Lydia’s sisters that she grew up with spent decades not knowing what happened to her after she disappeared from Texas in the 1990s.”
The breakthrough closes a long-running mystery surrounding McWhorter’s identity, even though authorities had known for years who killed her.
How Did Investigators Finally Identify Lydia Jane Wade McWhorter?
In 2010, Jesperson confessed to killing the woman he called “Claudia” (McWhorter) after encountering her while working as a long-haul truck driver.
He was sentenced to 25 years to life, but her true identity remained a mystery.
More than a decade later, the Riverside County Regional Cold Case Homicide Team reopened the investigation.
In late 2023, detectives visited Jesperson at Oregon State Penitentiary, where he provided more details about their encounter. He said he met “Claudia” (McWhorter) at a brake check area on Interstate 15 south of Victorville, Calif. in August 1992.

Jesperson said she asked for a ride to Los Angeles, but the two instead continued toward Arizona. He claimed they later argued about money at a rest stop in the Indio-Coachella area, where he killed her inside his truck before leaving her body near Blythe.
Meanwhile, advances in DNA technology and genetic genealogy allowed detectives to trace relatives on McWhorter’s paternal side. They determined her deceased biological father had ties to Cameron County, Texas, but still needed a maternal relative to confirm her identity.
In January 2024, the Riverside County District Attorney’s Office turned to the public for help.
The appeal eventually generated a lead that helped authorities locate McWhorter’s maternal family. Her sister, Brenda Burks, provided a DNA cheek swab, according to the Los Angeles Times.

Nearly 34 years after McWhorter’s body was found, the DNA provided the confirmation investigators had been seeking.
With McWhorter finally identified, Riverside County investigators have closed the last unidentified victim case connected to Jesperson’s known murders.
“I want to thank the public for the role you play in our investigations,” Billy Hester, supervising investigator of Riverside County’s Cold Case Unit, said in a statement. “Most importantly, I hope this will finally bring closure to Lydia’s family.”
Who Is the Happy Face Killer?
Jesperson has admitted to killing eight women between 1990 and 1995.
He earned the nickname the “Happy Face Killer” after writing letters to news outlets about his crimes and signing them with a smiley face.
Jesperson remains incarcerated in Oregon, where he is serving multiple life sentences.
