FOREST HILLS — A Forest Hills middle school teacher was sentenced to two to six years in jail after pleading guilty Tuesday to violating the terms of the probation he had received last year after admitting he sent sexual messages to adolescent boys online, Queens District Attorney Richard Brown said.
Bradley Dieffenbacher, a 32-year-old who formerly taught math at MS 190 in Forest Hills, admitted he failed to obey the terms of his probation by tutoring a 15-year-old boy in math between December 2008 and March 2009, according to Brown.
Dieffenbacher was not supposed to be in contact with minors after he pleaded guilty last year to sending eight of his 12- and 13-year-old math students sexually explicit messages and forwarded them pornographic links online between April 2007 and February 2008, the DA said.
As part of his original plea, Dieffenbacher surrendered his state teaching license and was required to register as a sex offender when he was sentenced last June to six months in jail and 4 1/2 years’ probation.
