Four (4) Years After An Unidentified Newborn Was Found Dead In The Ocean - Police Have Arrested The Mum + How They Found Her

Four-and-a-half years ago, a days-old newborn was found dead, floating in the ocean off the coast of Florida. The case turned cold with no fruitful leads and the female infant was never identified.

On Thursday, authorities in Palm Beach County said that they have arrested the mother of the infant with the help of the same genetic genealogy technique that led to an arrest in the "Golden State Killer" case in California.
