After 41 Years and False Confessions, Real Killer of a Colorado Woman Found Guilty of Manslaughter

Sylvia Quayle

The long quest for justice in the 1981 cold-case murder in the Cherry Hills, first derailed by a false confession and most recently by a misdemeanor, this week with the identification of a suspect decades after the murder through genetic detective work ended.

An Arapaho County jury on Thursday found 62-year-old David Dwayne Anderson guilty of first-degree murder after deliberation and first-degree felony in the 1981 murder of Sylvia Quayle in his home.

“For more than 40 years, the defendant kept a secret with him, a secret that finally came to light during the course of this trial,” Deputy District Attorney Grant Grosgebauer, one of the case’s prosecutors, said in a news release.

On August 4, 1981, Quayle’s father found the body of a 34-year-old inside his home in the 3800 block of South Ogden Street. Prosecutors said she was raped, stabbed multiple times and shot in the head.

Police investigation revealed that the attacker had cut off the telephone line of the house by opening the window.

Two years later, a self-proclaimed serial killer named Otis Tolle, who was already in custody in an unrelated murder case, confessed to the crime, prompting the local police to close their investigation – although Tolle never got on Quayle. was not charged with murder.

But in 1993, DNA testing proved Tool’s confession wrong. Police then resumed the investigation into Quayle’s murder, but the case remained cold for years.

It wasn’t until 2020 that new DNA analysis pinpointed Anderson of Nebraska as the prime suspect in the decades-old crime.

The Cherry Hills Village Police Department and United Data Connect, a genetic genealogy company, began working together and, in 2021, an investigator with United Data Connect went to Anderson’s residence and collected garbage bags to obtain a new DNA sample. .
