Leonard Lake (Charles Gunnar)

Leonard Thomas Lake was born on October 29, 1945, in San Francisco, California. Following his parents' divorce, he spent much of his childhood being raised by his maternal grandmother. Reports later suggested he displayed disturbing behaviour from an early age, including an obsession with pornography and violent fantasies.

Lake enlisted in the United States Marine Corps during the Vietnam War but was medically discharged after developing psychiatric problems. Throughout adulthood he drifted between jobs, marriages, and relationships while becoming increasingly interested in survivalism, firearms, and apocalyptic beliefs.

By the early 1980s, Lake had purchased a remote property in Wilseyville, California, where he began constructing bunkers, hidden rooms, and areas that investigators later linked to his criminal activities.

Between approximately 1983 and 1985, investigators concluded that Lake and Charles Ng abducted, imprisoned, and murdered numerous victims at the Wilseyville property.

The confirmed victims included men, women, and infants, many of whom were targeted for their vehicles, property, or because Lake sought complete control over them. Investigators recovered human remains belonging to at least 11 victims, although evidence suggested additional unidentified victims may have existed.

Following the discovery of the compound, detectives uncovered journals, videotapes, photographs, and written plans describing Lake's fantasies of creating a captive group of women following a fictional societal collapse, providing disturbing insight into the motivations behind the crimes.

Investigators determined Lake and Ng worked together to lure victims to the remote property, where they were restrained, imprisoned, and ultimately murdered.

Evidence recovered from the compound indicated meticulous planning, including concealed structures, restraints, weapons, surveillance equipment, and detailed records documenting aspects of the offences. Personal belongings belonging to victims were retained, while many bodies were buried or destroyed on the property.

The investigation demonstrated a highly organised partnership in which Lake planned much of the operation while Ng actively participated in the kidnappings, assaults, and murders.

On June 2, 1985, Leonard Lake was arrested after attempting to shoplift a vice from a hardware store in South San Francisco using identification belonging to one of his victims.

While in police custody, Lake swallowed cyanide capsules concealed on his person. He was transported to hospital but died several days later without revealing the full extent of the crimes.

Following his arrest, investigators searched the Wilseyville property and uncovered buried human remains, videotapes, journals, and extensive forensic evidence linking Lake and Charles Ng to multiple murders.

Because Leonard Lake died shortly after his arrest, he never stood trial.

The investigation instead focused on Charles Ng, who fled to Canada before eventually being extradited to California after lengthy legal proceedings. Ng was convicted in 1999 of 11 murders and sentenced to death.

Evidence recovered from Lake's property formed the foundation of one of the longest and most expensive murder prosecutions in California history.

The Leonard Lake investigation remains one of the most disturbing serial murder cases in American history because of the extraordinary amount of evidence recovered from the Wilseyville compound. Investigators found journals, videotapes, diagrams, and personal writings that documented Lake's long-standing fantasies of domination and captivity.

Although authorities officially linked Lake and Ng to 11 murders, many investigators believe the true number of victims may never be known because of incomplete remains and missing persons who were never conclusively identified.

Today, the Lake-Ng murders continue to be studied by criminologists because of the organised nature of the crimes, the partnership between the offenders, and the extensive documentary evidence left behind.
