Paul Holes was on the verge of retirement, having never completed his decades-long mission to catch the Golden State Killer. Then he had an idea: Upload DNA evidence to a genealogy website.
On today’s episode:
• Paul Holes, an investigator in California who helped to crack the case.
• A spate of murders and rapes across California in the 1970s and 1980s went unsolved for decades. Then, last week, law enforcement officials arrested Joseph James DeAngelo, 72, a former police officer.
• Investigators submitted DNA collected at a crime scene to the genealogy website GEDmatch, through which they were able to track down distant relatives of the suspect. The method has raised concerns about privacy and ethics.
The subtleties will be when we’re using this type of DNA evidence more frequently for lower level crimes while at the same time the technology gets increasingly cheaper to carry out.
