A Colorado murder mystery that baffled detectives for nearly four decades has been solved after one of the killer's relatives uploaded their DNA to a genetic genealogy database.
18-year-old Jeannie Moore was last seen hitching a ride to her job at a convenience store in
Lakewood on August 25, 1981, and her body was discovered five days later at a picnic ground in nearby Genesse Park.
An autopsy revealed that Moore had been r-ped and that she was killed by 'several blows to the head'.
Despite widespread media attention, and the fact that the murderer's semen was retrieved from a piece of Moore's clothing, the case went unsolved for almost 40 years.
However, a breakthrough came back in May, when the county's lead cold case detective, Elias Alberti, noted that California's infamous Golden State Killer had been identified after a relative uploaded their DNA to an ancestry website.
Given that investigators had a clean DNA sample from Moore's killer, Alberti decided to see whether there would be a possible match sitting in a database.
'It was a no-brainer,' the detective told The Denver Channel.
'We had no choice but to try to get in on it and see if we can use this technology to our benefit'.
The killer's semen sample was sent to United Data Connect who then uploaded it to Family Tree DNA.
Stunningly, it was revealed that someone related to the suspect had also put their results on the -database after they had taken a genetic genealogy test.
Alberti would not say which of the killer's relatives has taken the test, but family Tree DNA returned a list of the top 25 matches and detectives worked backwards to find a match.
After several weeks, investigators eventually matched the DNA to Donald Steven Perea, who died in May 2012 at age 54.
His daughter provided a DNA sample for the police, which revealed that Perea was 3.3 trillion times more likely than any other person to have killed Moore.
At the time Perea murdered Moore he has been out on bond after committing a separate violent r-pe
