FREEHOLD, N.J. — Authorities say a college professor and a former federal government contractor are among 14 men charged over the past two months as part of a child pornography sweep.

Monmouth County prosecutors say most of the people arrested in “Operation Schools Out” possessed or shared images and videos of children being sexually abused, ranging in age from infants to teenagers. Most of the suspects face child endangerment charges.

The men charged in the probe range in age from 18 to 69. The arrest made in late July and last month culminated a three-month investigation conducted by county, state and federal law enforcement agencies.
