From The New York Times:
It was the latest breakthrough in a cold case using genetic genealogy, the technique of tying suspects to DNA using samples that have been voluntarily submitted to commercial genealogy sites by their relatives. The tactic has been used to solve dozens of cases, but has raised ethical and legal concerns.

Investigators in Palm Beach County followed Mr. Hayes and obtained a DNA sample from a discarded cigarette butt last week. The DNA closely matched the DNA obtained from Ms. Bey, Captain Wallace said, as did an additional sample obtained after the arrest.
