An Easton man has been arrested for allegedly sexually abusing two children. Easton Police received a call earlier this month from Yale-New Haven Hospital about two patients seen for signs of sexual abuse and trauma. The victims were interviewed late last week and a warrant for 40-year old Robert McGuire was issued. Easton Police arrested him at his home on Friday and say evidence was recovered along with 12 firearms and a large amount of ammunition. The evidence is currently being examined by the Technical Investigation Unit. McGuire was held on a court set half a million dollars bond for an appearance today. He was charged with two counts of sexual assault and illegal sexual contact along with one count of risk of injury to a minor. Investigators from Darien, Weston, Westport, and Wilton assisted in the investigation.
