Quick Summary

Jancys Santiago, 50, received a 25-year prison sentence for raping Katy Vicchitto in her Bronx apartment in December 2001. This case was solved using a new DNA matching method called investigative genetic genealogy, which involved uploading crime scene DNA to an ancestry website and mapping out family trees. The technique helped identify Santiago as the suspect, leading detectives to confirm his identity with DNA from a discarded water bottle. Assistant District Attorney Gabrielle Martin-Klein emphasized the lasting impact of the attack on Vicchitto's life, while defense attorney Michael Croce plans to appeal due to concerns about the reliability of the scientific evidence used in court.

Story summary

In December 2001, Jancys Santiago, then aged 35, sexually assaulted Katy Vicchitto inside her Bronx apartment after binding her with wire coat hangers. This cold case was recently solved using a new DNA matching method involving family trees, marking the first such use in New York for solving cold-case rapes. In June 2023, a jury found Santiago guilty of first-degree rape. On Friday, Judge Laurence Busching sentenced Santiago to 25 years in prison, consecutive with an existing 20-year sentence he is serving for a separate 1999 Manhattan home invasion and rape. The judge emphasized the severity of the crime and its lasting impact on victims like Vicchitto, who described enduring daily reminders of the attack for over two decades. Assistant District Attorney Gabrielle Martin-Klein highlighted that Santiago had previously raped another woman in her Midtown apartment in 1999 using similar tactics, indicating a pattern of behavior and raising questions about past investigative methods' reliability.
