KINGSPORT, Tenn. (AP) — Investigators say a former Kingsport police officer accessed child pornography over wireless networks belonging to neighbors, businesses and a church. Richard Chandler is one of 72 people indicted in an investigation into an international child pornography network that prosecutors say used an online bulletin board called Dreamboard to access thousands of images and videos of sexually abused children. WJHL-TV reports (http://bit.ly/pWb8x8) that the federal search warrant alleges Chandler made 117 posts to the site, including twice when he was on duty.
