Man pleads not guilty to child sex abuse charges

(WEAU) - A man accused of child sex abuse has pleaded not guilty.

Online court records show Dennis Hess, 42, pleaded not guilty to two counts of repeated sexual assault of the same child and child exploitation Thursday. In March, police arrested Hess at his home in Bruce, on allegations he sexually assaulted a child in Altoona.

Police say it happened over a ten year period and they found computer evidence that led them to believe more kids may have been involved.
