The Golden State killer was the name pegged on Joseph DeAngelo a former police officer who lived a double life as a serial killer committing several atrocities back in the 70s and 80s.

Gay Hardwick, who is also a rape victim of Joseph, said in court Wednesday that she is certain DeAngelo is angling to be sent to “some prison nursing home for old murdering psychopaths”.
During one rape in 1978, DeAngelo sobbed and appeared to call out the name of his former girlfriend, saying, “‘I hate you, Bonnie,’ over and over,” investigator Paul Holes said in 2018.
In June, DeAngelo pleaded guilty to 13 murders and 13 rape-related charges between 1975 and 1986. He also publicly admitted dozens more sexual assaults for which the statute of limitations had expired.
The crimes went unsolved until April 2018, when DeAngelo, a father and grandfather, was arrested in Sacramento County.
DeAngelo was the first public arrest obtained through genetic genealogy, a new technique that takes the DNA of an unknown suspect left behind at a crime scene and identifies him or her by tracing a family tree through his or her family members, who voluntarily submit their DNA to public genealogy databases.
To identify DeAngelo, investigators narrowed the family tree search based on age, location and other characteristics.
Authorities conducted surveillance on DeAngelo and collected his DNA from a tissue left in a trash. Investigators plugged his discarded DNA back into the genealogy database and found a match, linking DeAngelo’s DNA to the DNA found at multiple crime scenes, prosecutors said.
Since The Golden State Killer’s arrest, over 150 other crime suspects have been identified through genetic genealogy.
