The El Dorado County District Attorney's Office says they've released new information on a cold case that happened in the late 1970's in the South Lake Tahoe area.

They said timeline photos have been released of the suspect in the case, Joseph Holt.

They said the Cold Case Task Force is continuing to investigate whether or not Holt is responsible for other unsolved crimes.

They are asking anyone who has witnessed or who has been a victim of crimes associated with Holt to contact them at the El Dorado County Cold Case Homicide Task Force Tip Line at (530) 621-4590.

Original Story: The El Dorado County DA's Office says it now has a suspect in a pair of murders in South Lake Tahoe that happened forty years ago.

Authorities say 27-year-old Brynn Rainey was found in a shallow grave back in 1977.

Two years later 16-year-old Carol Andersen’s battered body was found on the side of the road.

The cases remained unsolved for decades until a task force was able to use DNA testing to find male DNA on the bodies of both women.

The evidence suggested the murders were committed by the same person, and with the help of Parabon Nanolabs, a genealogical research company, they narrowed their search to three brothers who have all since died. 

Investigators finally identified Joseph Holt of South Lake Tahoe as a suspect in the murders after obtaining more DNA evidence.

Holt died back in 2014.

Last month police conducting a search warrant of Holt’s property found an article about a shooting in Los Gatos, California.

Investigators say the gun used in the shooting was stolen from South Lake Tahoe and a description of the suspect matched Holt.

With this evidence, the task force concluded that Holt killed both Brynn Rainey and Carol Andersen.

Authorities ask if you have any more information about the cases, or other unsolved cases, contact them at 530-621-4590. 

The DA's Office says Brynn Rainey’s family and Carol Andersen’s family are grateful to finally know who took their loved one so many years ago. They expressed their support for the use of this technology to solve crimes. Both families ask that the public respect their privacy.

Brynn Rainey’s brother, Pete Garl, stated, “Finally after 44 years of hell and back, we have some answers.”  

Carol Andersen’s family released the following statement.  

“Almost 40 years ago, a beautiful, vibrant teenager was taken from her mother, older sisters, younger brother, and younger sister. Unfortunately, relatively quickly the case went cold and while from time to time it would be revisited nothing could be found, until about a year ago. It was at that time that an incredible team of 4 investigators from the El Dorado County District Attorney’s Cold Case Files and through all their hard work and efforts, they were able to give the family some answers and closure and ultimately allow Carol Andersen to rest in peace!"

In closing, we, the family of Carol Andersen want to extend our warmest thanks and highest appreciation to the team from the El Dorado County District Attorney’s Office Cold Case Files for not giving up and not forgetting our sister and finally we ask that although we appreciate those of you in the press we do ask that you please respect our privacy and the memory of Carol Andersen, our sister who’s gone but never forgotten. Thank You, the Andersen Family.”

Parabon’s Chief Genetic Genealogist, CeCe Moore, said of the investigation, “This was a great collaborative effort with the detectives at EDCSO and the Cold Case Task Force. Our genetic genealogy team was fortunate enough to be able to generate good leads after which the casework and forensic laboratory analyses were exemplary. With that type of synergy we can expect to see many more cold cases solved.”
