From Texas Standard:
After 40 years, California authorities last week arrested a person they believe to be the “golden state killer,” responsible for at least 12 murders and dozens of rapes.
But the way police were able to catch this suspect is controversial to say the least. They tracked down Joseph DeAngelo through DNA that the suspect's family members' had uploaded onto an online genealogy website. Proponents say its revolutionary, but critics have called it "dystopian.”
