TRENTON, N.J. — A New Jersey school bus driver who admitted distributing images of child sex abuse over email has been sentenced to more than 10 years in prison.

Under the sentence imposed Monday, Christopher Walsh will also have to serve 10 years of supervised release once he’s freed. The 32-year-old Yardville man had pleaded guilty in February.

Federal prosecutors say that from June 2014 to January 2016, Walsh’s email account either sent or received 1,590 files that contained videos or images of child sexual abuse.

Walsh admitted that he emailed a video depicting child sex abuse to another person in August 2015.
