Westchester County prosecutors say they've nailed the headmaster of New York City's Trevor Day School in an Internet kiddie perv sting:

District Attorney Investigators arrested John H. Dexter (DOB 10/05/1943) of ...Tarrytown, New York and charged him with two counts of Attempted Disseminating Indecent Material to Minors, a felony. Dexter is the Head of School for the Trevor Day School in Manhattan.

It is alleged that between June 3, 2003 and October 22, 2003 the defendant had sexually explicit online conversations with two girls ages 14 and 15.

The girls were actually undercover investigators assigned to the High Technology Crimes Bureau of the District Attorney’s Office. Attempted Disseminating Indecent Material to Minors is a class E felony punishable by a maximum sentence of four years in state prison.

At the Trevor Day School's web site, Dextor's message to readers touts the school's programs, including an "Anytime Anywhere Laptop Program" for kids.

Tuition at the school ranges from $18,000+ for kindergartent to $25,000+ for high school, not including the laptop.
