January 1, DECADES-LONG MYSTERY: Final Victim of Notorious Serial Killer Finally Gets Her Name Back

Wyatt’s Take

• After 34 years, California authorities finally identified the last unknown victim of serial killer Keith Jesperson — a Texas woman whose family spent decades wondering what happened to her
• Breakthrough came through good old-fashioned detective work and DNA genealogy, proving that persistent law enforcement can deliver justice even when cases go cold for generations
• This monster is already serving multiple life sentences in Oregon, but giving this victim her name back matters — families deserve answers and closure

The final unidentified victim of notorious serial killer Keith Hunter Jesperson, known as the “Happy Face Killer,” has been identified more than three decades after her body was discovered along a California highway. Authorities announced Thursday that the woman they’d known only as “Claudia” for over 30 years was actually Lydia Jane Wade McWhorter of Texas.

The Riverside County District Attorney’s Office made the identification after DNA testing confirmed a connection to a member of McWhorter’s maternal family. Her body was discovered August 30, 1992, along Highway 95 about seven miles north of Blythe, California.

Jesperson, a long-haul truck driver who confessed to killing eight women across multiple states, later admitted to killing her. He told investigators he knew the woman as “Claudia,” but authorities were unable to determine whether that was her real name — until now.

The identification comes after Riverside County investigators publicly renewed their effort to identify McWhorter in 2024. Genetic genealogy had connected the unknown victim to relatives on her father’s side but had not produced the maternal connection needed to confirm her identity.

DNA testing had identified Summer Gonzales as the victim’s paternal half-sister. Gonzales said she wanted to learn her sister’s real name and eventually lay her to rest with family.

An investigative lead ultimately brought the cold case team to one of McWhorter’s direct maternal relatives. Investigators then identified a possible genetic connection to another member of the maternal family.

A DNA sample confirmed that connection earlier this week, allowing investigators to positively identify McWhorter nearly 34 years after her body was found. McWhorter’s sisters, who grew up with her, had spent decades without knowing what happened to her after she disappeared from Texas in the 1990s.

“I want to thank the public for the role you play in our investigations,” Billy Hester, supervising investigator of the Cold Case Unit, said in a news release.

“When people take the time to share information, submit a tip or simply pay attention to what is happening in their community, it can make a real difference. You may not know where a piece of information will lead, but our investigators will follow it. Most importantly, I hope this will finally bring closure to Lydia’s family.”

The district attorney’s Division of Victim Services is working with McWhorter’s family as they decide how to honor her and lay her to rest. After decades of uncertainty, they can finally bring her home.

Jesperson was arrested in 1995 and eventually confessed to killing eight women between 1990 and 1995 in California, Washington state, Oregon, Florida, Nebraska and Wyoming. He became known as the “Happy Face Killer” after sending letters about his crimes to the media that he signed with a smiley face — a sick calling card that turned his evil into a twisted joke.

He pleaded guilty to McWhorter’s murder in Riverside County on January 8, 2010, and was sentenced to 25 years to life in prison. He is serving multiple life sentences in Oregon.

With McWhorter’s identification, Riverside County’s cold case team has now closed the final unidentified-victim case tied to the murders for which Jesperson was convicted.

Why This Matters

This case shows what happens when law enforcement refuses to give up on the forgotten. For 34 years, this woman had no name — just a monster’s lie and a cold case file. But dedicated investigators kept working, kept searching, and finally gave Lydia Jane Wade McWhorter her identity back. Her family can finally grieve properly and lay her to rest with dignity. That’s what justice looks like — not flashy, not quick, but determined and thorough. Every victim deserves a name. Every family deserves answers. And every criminal needs to know that Americans don’t forget.
