A former Brooklyn teacher has entered a guilty plea on charges related to the sexual exploitation of minors. The ex-math instructor, identified as Winston Nguyen, 38, from Harlem, New York, pled guilty to one count of using a child in a sexual performance and five counts of endangering the welfare of a child. This deal was struck in exchange for a seven-year prison sentence coupled with sex offender registration. The sentencing is set for March 17, the Brooklyn District Attorney's office has reported.
The disturbing case, which unfolded over nearly two years, involved Nguyen coaxing teens from four independent Brooklyn schools into sending him explicit images. While working at Saint Ann's School, he maneuvered his way into their trust by posing as a teenager on Snapchat, engaging them in sexually explicit conversations. The victims in these incidents ranging from 13 to 15 years old. As part of his ploy, Nguyen used two Snapchat accounts – "hunterkristoff" and "haircutbongos" – which were eventually traced back to his residence by digital forensics teams, according to the Brooklyn District Attorney's announcement.
“Today’s plea holds this defendant responsible for his disturbing and predatory conduct while sparing young and vulnerable victims from ever having to testify about their traumatic experiences. This kind of exploitation of children, made even more distressing by the fact that the defendant was a trusted school figure, will never be tolerated in Brooklyn and we will continue to expose and root it out. I would like to acknowledge the detectives and prosecutors from my office who investigated this complicated case and ensured that justice is done,” District Attorney Eric Gonzalez stated. The case was thoroughly investigated by the KCDA Detective Investigators alongside the District Attorney's Digital Evidence Lab, as mentioned by the same press release.
The prosecution was led by Senior Assistant District Attorney Daniel Brian Newcombe, who navigated the intricate terrain under the guidance of prosecutors from the Special Victims Bureau. The investigators, using digital forensics, were able to stitch together the digital trail leading to Nguyen, roping in accounts from the victims and other digital communications.
