Rochester, NY—State Police have arrested a University of Rochester instructor for possessing child pornography and have alleged that the suspect was tipped off by a University official.

According to WROC-TV, “Gilbert Kirton, 26, of Rochester was charged Friday with one count of possessing an obscene sexual performance by a child.”

Police also said Kirton's arrest comes despite being told about the investigation by a Dean at the U of R. Investigators have been looking into Kirton for four months, based on a tip from the Montgomery County, Pennsylvania police department.

The Dean has not been publicly identified. However, another local TV station, WHAM, has reported that the official was “a director of graduate studies at the university” and police referred to the tipster as a male:

Captain Scott Crosier says, "obviously he conveyed enough information to him that caused Mr. Kirton to dismantle his computer and attempt to get rid of it by placing it in six different garbage bags and in six different trash receptacles on the campus. So obviously Mr. Kirton felt that there was enough information was conveyed to him that he realized that the computer was the source of the problem."

The police allege that the images seized from Kirton’s computer were "some of the most sexually graphic images depicting the physical and sexual abuse of children secured by the state police in Western New York."

At this point, there is no indication that the University official who tipped off Kirton will be charged, WROC reported. According to WHEC-TV, the official learned of the investigation, and tipped Kirton off, after police contacted him to verify Kirton’s employment information.

Kirton was arraigned in Monroe County Court and was remanded to the Monroe County Jail in lieu of $5,000 cash bail or $15,000 bond. If convicted in federal court, he faces ten to fifteen years in prison.
