Quiogue man charged with 'sexual conduct' against girl, 11, Southampton Town police say

A 19-year-old Quiogue man has been indicted on sex charges after police said he had "repeated intercourse" with an 11-year-old girl, beginning in March 2021.

Southampton Town police identified the man as Kelvin F. Mayen-Vasquez and said he claimed he had developed a "romantic interest" in the girl.

The identity of the girl was not released because of her age and because she is the victim of an alleged crime. Police said the charges cover illegal sexual conduct beginning in March 2021 and continuing through this month, but did not detail how Mayen-Vasquez met the girl.

Police said Mayen-Vasquez was arrested May 19 and charged with course of sexual conduct against a child, possessing a sexual performance by a child and endangering the welfare of a child.

Police said he was arraigned on those charges in Southampton Town Justice Court.

Court records show that Mayen-Vasquez is being held at the county jail in Riverhead and is scheduled for arraignment in county court in Riverhead on May 31, following the indictment.

It was not immediately clear if Mayen-Vasquez is represented by counsel.
