A 26-year-old man from Wheatley Heights, New York has been indicted on charges of rape and endangering the welfare of a child for allegedly engaging in sexual acts with two 14-year-old girls he met on the social media platform Snapchat between December 2024 and June 2025. Prosecutors say Kemuel St. Juste used the Snapchat handle "k3mnyy" to contact and exploit the underage victims.

Why it matters

This case highlights the growing problem of adults using social media to sexually prey on minors, as well as the need for greater education and awareness around online safety for young people. It also raises questions about how to better monitor and regulate social media platforms to prevent such exploitation.

The details

According to prosecutors, St. Juste first contacted a 14-year-old girl on Snapchat in December 2024 and met up with her at a TJ Maxx store, where he allegedly had sexual intercourse with her in a bathroom. He is also accused of picking the girl up from her middle school in early January 2025 and having sex with her in his car. In June 2025, St. Juste allegedly approached a different 14-year-old girl at a county park, asked her to add him on Snapchat using the same handle, and then drove her to a parking lot in Port Jefferson where he had sex with her.
