"Schene told investigators through an e-mail conversation with his lawyer that once he was assaulted by the girl kicking her shoe at him, he entered the cell to 'prevent another assault,' according to court documents.
Schene also said the girl failed to comply with instructions in the holding area.
Prosecutors said Schene did not explain why he struck the girl after he had her in a holding position on the floor."

But yeah, what COULD be the whole story nynth? I know... this one's easy.
She murdered his cop friend and while batman was away she revealed to him that his cop friend begged for his life. He then said "I'm gonna enjoy this" and wilded out.
Totally reasonable.
