His name was Herbert Rice. He died of cancer in 1991, with two sons who had no idea what he’d done, Bottari said. In the sweeping and exhaustive investigation of the murder, in which police canvassed dozens of streets and interviewed hundreds of people, Rice had never attracted suspicion. He had a short record of arrests for nonviolent offenses, which did not require him to provide a DNA sample that would have been put in criminal databases. A query for relatives in the criminal database, known as a familial DNA search, failed as well.

It was the new technology, known as genetic genealogy, that finally gave police the answer.
