A dirty tissue led to the arrest of one of the most-prolific serial killers in U.S. history, according to a newly unsealed search and arrest warrant.
Joseph DeAngelo is accused of being the notorious Golden State Killer, East Area Rapist and Original Night Stalker.
ABC News is reporting an unsealed 100-plus page warrant for DeAngelo reveals the initial DNA collected to connect DeAngelo to the murders of Lyman and Charlene Smith in March 1980 was taken off his driver’s side car door handle in April 2018.
Additional DNA samples were then sourced from DeAngelo’s trash. A piece of tissue was the conclusive DNA factor needed to link him to the these crimes, the warrant shows.
The DNA that was derived from the Lyman and Charlene Smith killings case was provided to the task force organised by the Sacramento County District Attorney’s Office, the district attorney’s office said.
Authorities compared the DNA from the Smith double murder to what’s available on genealogy websites to find a family tree for the suspect.
Officials then worked their way down that family tree until they found the 72-year-old DeAngelo.
DeAngelo was a police officer in Exeter, California, from 1973 to 1976, officials said. He then served as a police officer in Auburn, California, in 1979 before being fired for stealing a hammer, according to multiple reports.
