A federal district judge in Columbus has sentenced a Chillicothe man to seven years in prison after prosecutors say police found more than 16 thousand images and videos of child pornography on his computer and thumb drive. Prosecutors say officers in September 2013 linked 59 images of sexually abused children between ages 1 and 7 to the IP address of 46-year-old Daniel Akehurst. A subsequent search turned up the rest of the material.
