ALLEGHENY CO., Pa. (WPXI) – An Allegheny County 911 dispatcher has been suspended after he was charged with assaulting his 2-month-old son. Michael Koban, 34, is facing charges of aggravated assault and endangering welfare of children after investigators said he caused multiple the baby to have skull and rib fractures. According to a police criminal complaint, emergency responders first were called to his home on Bower Hill Road in Scott Township on Sept. 3 around noon. Koban was watching two of his sons — 2-months and 17-months-old, respectively — and then texted his wife saying the youngest child was hurt. Koban initially told police that his 2-month-old son had fallen from his swing in the living room and hit his head, causing a large bump. However, when doctors evaluated the baby, he was found to have a skull fracture, “underlying intracranial hemorrhage, and healing rib fractures.” The rib fractures were between two and five weeks old, and doctors told investigators those injuries more than likely were caused by a “squeeze or possible strike.”
