ROCHESTER, N.Y. (WENY) -- A Penn Yan man could face up to 20 years in prison, a lifetime of supervised release, and a $250,000 fine, after being convicted on child pornography charges.

Jeffrey Maciejewski, 26, pleaded guilty to possession of child pornography involving more than 600 images, some of which depicted the sexual abuse of infants and toddlers.

Assistant U.S. Attorney of the Western District of New York Kyle Rossi, who is handling the case, state that in May 2018, FBI Special Agents seized a number of electronics containing such pornography, which was being traded online via social networking platforms.

Based on that information, investigators identified several individuals, including the defendant, who were actively involved.

The information was sent to the Corning Office of the FBI, who, with the assistance of the Penn Yan Police Department, identified Maciejewski as a substitute teacher for the Penn Yan Central School District. Special agents acted quickly to obtain search warrants and located Maciejewski, who was ultimately interviewed at the school district's offices, according to a press release.

Sentencing is scheduled for February 21, 2020, at 10 a.m.
