About Herbert Mullin

Lived 1947 – 2022 (aged 75). Herbert Mullin was an American serial killer.

Herbert William Mullin (April 18, 1947 – August 18, 2022) was an American serial killer who killed 13 people in California in the early 1970s. He confessed to the killings, which he claimed prevented earthquakes. In 1973, after a trial to determine whether he was legally insane or culpable, he was convicted of two murders in the first-degree and nine in the second-degree and sentenced to life imprisonment. During his imprisonment, he was denied parole eight times.

Mullin and Edmund Kemper overlapped in their 1972 to 1973 murder sprees, adding confusion to the police investigations and ending with both being arrested within a few weeks of each other after the deaths of 21 people.

Early life, education, and mental health issues Herbert William Mullin was born on April 18, 1947, in Salinas, California. His father was reportedly stern but not abusive. Not long before Mullin's fifth birthday, the family moved to San Francisco.

Mullin had numerous friends and was voted "Most Likely to Succeed" by his classmates at San Lorenzo Valley High School. The school is in Felton, one of several small Santa Cruz Mountains towns, a short drive from the city of Santa Cruz. Yet the 16-year-old Mullin also experienced difficulties at this time, largely due to paranoid schizophrenic disorder. Shortly after high school graduation in 1965, one of Mullin's friends, Dean Richardson, was killed in a car accident. The death devastated Mullin, who then built "shrines" to Richardson in his room and became obsessed with the idea of reincarnation. He attended Cabrillo College in Aptos, in southern Santa Cruz County, where he earned an associate degree in civil highway technology in 1967.

In 1969, Mullin was admitted to Mendocino State Hospital. Over the next few years, he entered five mental hospitals and was discharged when deemed to pose no risk of harm to himself or others. By his mid-twenties, he had a diagnosis of paranoid schizophrenia, accelerated by his usage of LSD.

Murders

By 1972, Mullin was 25 and had moved back in with his parents in Felton, California, in the Santa Cruz Mountains. White had offered to help fix his car in exchange for a ride. Mullin dragged White's body into the woods, where it was found the next day. He later claimed his victim looked like Jonah from the Bible and sent him telepathic messages: "Hey, man, pick me up and throw me over the boat. Kill me so that others will be saved." He offered Guilfoyle a lift and stabbed her in the chest while driving. He later disemboweled Guilfoyle's corpse to examine her organs for evidence supporting his ideas on pollution. his former friend from high school who first introduced him to cannabis, and whom Mullin subsequently perceived as the originator of Mullin's eventual heavy drug use. In early January 1973, Mullin drove to a remote area of Santa Cruz, recalling Gianera had lived there. The resident of the first house Mullin approached was a woman named Kathleen "Kathy" Francis, a close friend of Jim Gianera and his wife Joan; Francis directed Mullin to Gianera's actual inhabitance (a cabin further down the same road). Mullin proceeded to Gianera's home, where he demanded to know why Gianera offered him the early taste of cannabis that Mullin alleged ruined his life. Mullin decided that the former friend's answer was unsatisfactory and shot him. Dying, Gianera crawled to his bathroom in an attempt to tell his wife to lock the bathroom door, but Mullin broke down the door and fatally shot her too. Mullin then returned to the home of Kathy Francis and shot her and her two children, four-year-old Daemon Francis and nine-year-old David Hughes, to death, then stabbed each victim multiple times after death. The police thought that the deaths in both homes were drug-related and did not suspect they were in any way connected with the priest's death or the previous murders of hitchhikers.

About a month later, on February 10, 1973, Mullin was hiking in the state park in Santa Cruz, where he encountered four teenage boys (Robert Spector, aged 18, Brian Scott Card, 19, David Oliker, 18, and Mark Dreibelbis, 15) camping illegally. He walked over to them, engaged them in a brief conversation, and claimed to be a park ranger. He told them to leave because they were, according to Mullin, "polluting" the forest. However, they shooed him away and stayed in the tent. The next day, Mullin returned and shot all four of them in the head with his .22 caliber pistol, killing them. When he had finished, he took their .22 caliber rifle and 20 dollars.

The next killing happened before the bodies of Mullin's previous victims were found later that week. On August 19, 1973, after fourteen hours of deliberation, Mullin was found guilty of first-degree murder in the killings of Jim Gianera and Kathy Francis — because they were deemed premeditated — and eight counts of second degree murder in the other killings — because they were considered "impulse" by the jury. Mullin was convicted of the ten murders at the age of 26.

The Santa Clara County District Attorney's Office charged Mullin for the murder of Henri Tomei. On December 11, 1973, the day his trial was to begin, he pled guilty to second-degree murder after originally pleading not guilty by reason of insanity to first-degree murder. He was sentenced to life imprisonment in the Santa Cruz County trial and was denied parole eight times since 1980. He was incarcerated at Mule Creek State Prison, in Ione, California.

Kemper described Mullin as having a "lot of pain inside, he had a lot of anguish inside, he had a lot of hate inside, and it was addressed to people he didn't even know because he didn't dare do anything to the people he knew." In that same interview, Kemper called Mullin "a kindred spirit there" due to their similar past of being institutionalized. Kemper said he told Mullin, "Herbie, I know what happened. Don't give me that bullshit about earthquakes and don't give me that crap about God was telling you. I says you couldn't even be talking to me now if God talking to you because of the pressure I'm putting on you right now, these little shocking insights into what you did, God would start talking to you right now if you were that kind of ill. Because I grew up with people like that."

Death

On August 18, 2022, Mullin died at age 75 from natural causes while housed at the California Health Care Facility.
