2008_02_liteach.jpgA former math teacher at MS 190 in Forest Hills was arrested for child endangerment after allegedly sending former and present male students lewd instant messages. Bradley Dieffenbacher, 33, of Long Island, had worked at MS 190 since 2000 until his resignation on February 14, when investigators confronted him.

According to the Queens DA's office, between April 1, 2007 and February 20, 2008, Dieffenbacher instant messaged eight boys, ages 12-13, who were either current or former students, asking them "if they masturbated, if they liked pornography, if they had a web cam and if they – Dieffenbacher and the student – could masturbate together and broadcast themselves masturbating over the web cameras."

Dieffenbacher allegedly watched one of the student masturbate over a webcam and also sent some links to porn sites. Queens DA Richard Brown said, "The charges are very disturbing. A teacher is accused of preying on the young students he is entrusted to teach. A classroom should always be a safe place for a child."

Dieffenbacher is being held on $150,000 bail and faces up to 15 years in prison. A MS 190 colleague told the Daily News, "He was a really good teacher and there was no hint whatsoever. It's terrible."
