Cops were originally called to the Dwyer home because of a domestic disturbance. They did not make an arrest because the wife told them Dwyer was not present (he was hiding in a bathroom) after he allegedly threatened to commit suicide if she told the police. She took her son and left town after the incidents, returned recently and filed a report with police on 9/11/14 and this is the result of that investigation.
Police say that Dwyer hit his wife (head butted her, breaking her nose on July 21, then punching her on July 22) and threw a shoe at their baby boy.
Dwyer denies ever striking his wife or son, insisting that he just punched the walls of their home, threw a cell phone and that his wife bit his lip. He did acknowledge hiding from police and sending a text with a photo of a knife with suicidal threats.
He was charged with aggravated assault resulting in a fracture, aggravated assault against a minor, assault, criminal damage & preventing someone from dialing 911.
All that's from the ESPN report.
