After more than three decades, Ventura police have solved the murder of a 42-year-old woman who was found dead on a hillside in 1991.
In a statement released on Tuesday, investigators say that the use of advanced genetic genealogy techniques led to them finally being able to identify the perpetrator after 33 years.
The body of Danielle Clause was discovered on a hillside near the top of Tioga Drive close to downtown Ventura on July 16, 1991, the statement said. An autopsy showed that she had been sexually assaulted and died due to multiple blunt-force injuries to her head.
The lengthy investigation spanned over the years, but after "investigators at the time explored every avenue, the case was suspended and considered cold," according to a statement from the Ventura Police Department.
In 2021, detectives decided to reopen the case to retest evidence gathered from the crime scene for DNA. They were able to locate genetic genealogy and develop a family tree of the perpetrator.
"Phenotyping was used to verify distinct characteristics of the suspect, and after collecting family DNA samples, Larry Welch was positively identified," said a statement from VPD.
In 1999, Welch passed away, and authorities confirm there is no known link between the two individuals.
"I am thrilled to announce this success story, achieved through close collaboration with local and national law enforcement agencies and non-profit organizations," stated Chief Darin Schindler of the Ventura Police. "From the initial inquiry in 1991 to recent advancements in forensic methods, I commend the dedication of our detectives as they persisted in seeking justice for the victim and her family."
The Ventura police department unveiled a detailed video outlining the extensive steps taken during the investigation, including a deeper look into how genealogy was utilized to identify Welch.
