Judge adds 25 years after genetic genealogy links man to 2001 rape
A Bronx judge imposed 25 additional years on Jancys Santiago after prosecutors used investigative genetic genealogy to prove he committed a 2001 Bronx rape, resulting in New York's first jury conviction secured with that technique. Santiago was already serving more than 20 years for a separate 2000 Manhattan rape, and the new sentence will be added to the earlier 20-year term, effectively ensuring long-term incarceration. Investigators matched semen from the 2001 scene to DNA linked to an unsolved Manhattan rape, leading to Santiago's 2023 arrest and subsequent convictions, and prosecutors said a 2023 DOJ grant aided cold-case work.
