The Earthquake Mission: How Schizophrenia Became Justice

Neighbor Notes the License Plate as Killer Shoots Seventy-Two-Year-Old Fred Perez: The Serial Murders of Herbert William Mullin

Fred Perez was trimming his garden in broad daylight when a truck stopped in front of his house. One shot. He fell dead while neighbors watched from their windows. One of them wrote down the license plate-a single detail that would untangle thirteen unsolved deaths across Santa Cruz County and expose a killer the system had released again and again.

In this episode, we trace the psychiatric decline of Herbert William Mullin and the catastrophic failures of California's mental health system. We examine the contradiction between his documented paranoid schizophrenia and his calculated return to the Llaneras home to eliminate a witness. We ask the question the jury faced in 1973: if a man kills obeying voices only he can hear, can the law hold him responsible?

Victim: Fred Perez
Date: February 13, 1973
Location: Santa Cruz, California
Status: Solved

- Herbert William Mullin was diagnosed with paranoid schizophrenia in 1968 but was released repeatedly from psychiatric facilities under California's 72-hour involuntary detention law.
- Mullin believed Albert Einstein's death, his own birthday, and the 1906 San Francisco earthquake were connected signs commanding him to kill and prevent earthquakes.
- He killed thirteen people in four months-a priest in a confessional, a hitchhiker, four campers, two children aged four and nine-but only ten crimes were formally charged due to insufficient evidence.
- After killing the Llaneras family, Mullin left the scene, then returned and killed family friend Kathleen Prentice and her two children, suggesting calculated witness elimination that contradicted claims of complete psychosis.
