Can Genealogy DNA Link To The Wrong Suspect? (with clip)
April 3, 2019
"SACRAMENTO (CBS13) — The technique that led to the arrest of the alleged Golden State Killer has now helped police in Alabama crack a decades-old double murder. The suspect in court Wednesday claims he’s innocent, but as this type of crime fighting becomes more common, some are wondering if genealogy DNA can link to the wrong suspect.
CBS13 investigator Julie Watts found that yes, DNA can get it wrong, and it has. In fact, genealogy DNA led to a different suspect in the Golden State Killer case before police arrested Joseph DeAngelo....
Parabon has helped solve nearly 50 cold cases. Moore said the company’s work generates leads.
“We’re providing a highly scientific tip, but no one’s going to be arrested based on what we say alone. Law enforcement has to take that tip and then go and build their traditional forensic case against this person,” Moore said.
The technique has faced criticism from privacy advocates, and a 2014 British study on familial DNA searches reportedly found an 83 percent failure rate.
Investigators in the Golden State Killer case even misidentified a 73-year-old Oregon man as their suspect before finding DeAngelo, because the two men had the same rare genetic marker....
...It is important to note that this type of evidence has not been used in trial yet. The Golden State Killer case will likely be the first to use it."
