DERBY, Kan. (AP) — Court records say more than 250 images and videos of child pornography were found on the electronic devices seized from a fired Kansas middle school teacher and coach.

New details about 37-year-old Cody Chitwood were included in the arrest affidavit. Chitwood was charged earlier this month with 11 counts of sexual exploitation of a child.

Derby school district spokeswoman Katie Carlson said school board members voted 6-0 Monday to fire Chitwood “effective immediately.” Chitwood was hired by the district in 2004. He taught special education at Derby Middle School and coached football, track and girls’ basketball.

Chitwood told investigators that “when you’re on the internet you see a lot of things” but added that he “never knowingly nor willing traded child pornography on any website.”
