Florida Man Indicted in NY’s First Use of Investigative Genetic Genealogy to Solve Cold Case Rapes

Bronx District Attorney Darcel D. Clark, Manhattan District Attorney Alvin Bragg, and New York City Police Commissioner Edward A. Caban announced that a Florida man has been charged in separate indictments for raping a woman in the Bronx and a woman in Manhattan two decades ago, after new DNA technology linked him to the brutal attacks. These are the first sexual assault cases in the state solved with Investigative Genetic Genealogy. A three-year, $500,000 grant from the U.S. Department of Justice’s Bureau of Justice Assistance to the Bronx District Attorney’s Office to solve cold cases was used to fund Investigative Genetic Genealogy. This entails taking crime scene evidence and sending it to a private laboratory to develop a profile which is used to search for consumer DNA databases for genetic relatives who consented to assist law enforcement. Using the suspect’s DNA found at the scenes, a family tree was developed by NYPD’s Forensic Laboratory, and those results helped identify the defendant as Jancys Santiago, 48.
