## Resource

A man convicted of two sexual assaults from two decades ago is now facing 25 years in prison — thanks to a groundbreaking forensic technique: investigative genetic genealogy. Law enforcement used DNA from the crime scene, matched it to a distant relative’s profile on a genealogy site, and built a family tree that led directly to Jancys Santiago — making this the first time in New York such a conviction was secured in a cold case. The method, also used to catch the Golden State Killer, has revolutionized solving old crimes where traditional databases fail — especially when suspects have no prior record. For victims, the conviction brings long-overdue justice; one survivor described enduring trauma so profound it altered her entire life — yet she preserved evidence with courage. But experts warn: while powerful, the technology demands strict oversight to protect privacy, prevent errors, and avoid wrongful arrests. Some argue it should be reserved for violent crimes only. As Santiago’s defense challenges the science’s reliability, prosecutors stand by it — sparking a national debate over how to harness this tool responsibly without sacrificing accuracy or civil liberties.
