Charles Ng

Their victims included their neighbour Lonnie Bond; their neighbor’s girlfriend, Brenda O'Connor; Lonnie Jr., the Bonds’ infant son; Harvey Dubs; Deborah Dubs; and their young son Sean. According to court records, they killed the men and infants immediately but kept the women alive, raping and torturing them, before murdering them or allowing them to die from their injuries. Other known victims included relatives and friends who came looking for Bond and O'Connor, two gay men and some workmates of Ng.

As of July 2019, Ng remains on death row at San Quentin State Prison. No executions have taken place in California since 2006.

Leonard Lake's wife, Claralyn Balazs, cooperated with investigators and received legal immunity from prosecution. Court records stated that Balazs turned over weapons and other material to authorities during the investigation. Balazs was called as a key witness in Ng's trial in 1999. Ng's lawyer, William Kelley, in a surprise move, dismissed Balazs without asking any questions. Kelley later declined to explain his actions. Balazs was on the witness stand for a few minutes as Kelley read sections of her immunity agreement. Balazs was expected to shed light on what happened inside the mountain cabin that her parents owned.

In February 1999, Ng was convicted of eleven of the twelve homicides: six men, three women, and two male infants; jurors deadlocked on the twelfth charge. Ng was sentenced to death, and the presiding judge rejected a motion to reduce the jury's verdict to life imprisonment. "Mr. Ng was not under any duress," he said, "nor does the evidence support that he was under the domination of Leonard Lake." Ng's prosecution cost the State of California approximately $20 million, at the time the most expensive trial in the state's history.

Ng went through a total of 10 attorneys, some of whom ended up defending him a second time. He also filed a malpractice suit against several of the attorneys, citing incompetent representation. After claiming that he had lost trust and confidence in all of his lawyers, he was allowed to represent himself, which delayed the trial another year while he researched applicable laws. His trial finally began six years after his extradition in October 1998.

Ng fought a protracted legal battle against extradition on the grounds that Canada, which does not have the death penalty, would be violating the Canadian Charter of Rights and Freedoms by permitting him to stand trial in California for capital murder. A habeas corpus petition and an appeal to the Alberta Court of Appeal were both denied. In 1991, the Supreme Court of Canada also ruled against him, and he was extradited to California later that year.

Ng and Lake's rampage might have gone on longer if not for Ng's kleptomania. On 2 June 1985, Ng was caught shoplifting a vise from a South San Francisco hardware store and fled the scene. Lake later drove to the store and attempted to pay for the vise, but by then the police had arrived. Officers noticed that Lake bore no resemblance to the photo on his driver's licence, which carried the name of Robin Stapley, a San Diego man reported missing by his family several weeks earlier. After a gun equipped with a prohibited silencer was found in the trunk of Lake's vehicle, he was arrested and positively identified via a fingerprint search. In custody, while awaiting arraignment, Lake swallowed cyanide pills that he had sewn into his clothes and died four days later.

Ng, meanwhile, had fled to Calgary, Alberta, Canada, where his sister lived. He lived, undetected, in a lean-to in Fish Creek Provincial Park until his penchant for theft did him in yet again. On 6 July 1985, he was arrested by the Calgary Police Service after shooting security guard Sean Doyle in the hand while resisting arrest for stealing a can of salmon from a Calgary department store. He was charged and subsequently convicted of shoplifting, assault with a weapon, and possession of a concealed firearm, and was sentenced to four and a half years in prison. After serving his sentence, he remained incarcerated pending an extradition request from California authorities.

The license plate on Lake's vehicle was registered to him, but the vehicle itself was registered to Paul Cosner, who had disappeared in November 1984. Lake's auto registration led detectives to the property in Wilseyville, where they found Stapley's truck and Bond's car, and behind the cabin, the dungeon. In a makeshift burial site nearby, police unearthed roughly 40 pounds of burned and crushed human bone fragments corresponding to a minimum of 11 bodies.

They also found a hand-drawn "treasure map," leading them to two buried five-gallon buckets. One contained envelopes with names and victims' IDs, suggesting that the total number of victims might have been as high as 25. In the other bucket were Lake's handwritten journals for the years 1983 and 1984, and two videotapes documenting the torture of two of their victims. In one of the tapes, Ng is seen telling victim Brenda O'Connor, "You can cry and stuff, like the rest of them, but it won't do any good. We are pretty ... cold-hearted, so to speak." In the other, Deborah Dubs is shown being assaulted so severely that she "could not have survived."

In 1982, federal authorities raided the mobile home they shared in Ukiah, seizing a large stash of illegal weapons and explosives. Lake was released on $6,000 bond. He jumped bail and drifted around the state, using a series of pseudonyms. Ng was returned to the Marines' custody and pleaded guilty to the theft and desertion charges. Under the terms of his plea deal, he was paroled and discharged in 1984 after serving 18 months in the military stockade at the United States Disciplinary Barracks Fort Leavenworth.

Ng became a Marine in 1979 with the help, he claimed, of a recruiting sergeant and false documents attesting to his birth in Bloomington, Indiana. After less than a year of service, he was arrested by military police for theft of automatic weapons from MCAS Kaneohe Bay in Hawaii. Facing court-martial, he escaped custody in 1980 and made his way back to northern California, where he reunited with Lake.

Ng moved to the United States on a student visa in 1978, and studied biology at the College of Notre Dame in Belmont, California. He dropped out after one semester. At that time, he met Leonard Lake. Soon after, he was involved in a hit and run accident, and to avoid prosecution he enlisted in the United States Marine Corps.

Charles Ng Chi-Tat (Chinese: 吳志達 ; Jyutping: ng zi daat ; born 24 December 1960) is a convicted Hong Kong-American serial killer who committed numerous crimes in the United States. He is believed to have raped, tortured and murdered between 11 and 25 victims with his accomplice Leonard Lake at Lake's cabin in Calaveras County, California, in the Sierra Nevada foothills, 60 miles from Sacramento. After his 1985 arrest and imprisonment in Canada on robbery and weapons charges, followed by a lengthy dispute between Canada and the US, Ng was extradited to California, tried, and convicted of 11 murders. He is currently on death row at San Quentin State Prison.
