(Fox News) A prosecutor who helped put an upstate New York gym teacher behind bars for molesting an 8-year-old boy said he was stunned by the lack of cooperation he got from the Matthew LoMaglio’s colleagues, 22 of whom wrote letters to the judge supporting him.

LoMaglio, 37, who was found guilty in November of second degree sexual conduct against a child and endangering the welfare of a child was sentenced last week to four years in prison. But the process of bringing him to justice for the crimes, which occurred in 2006 and 2007, was complicated by the victim’s fear and the unwillingness of other teachers at Rochester School 19 to cooperate with the investigation, according to Monroe County Assistant District Attorney Kyle Rossi.
