The Brown County District Attorney’s Office has dropped charges against a man from Arkansas who allegedly assaulted his girlfriend’s 11 month-old daughter while he was working a temporary job in Green Bay. The DA will not explain why charges were dropped on 37 year old Derek Gates, and now the mother of the child Amanda Sargent, is confused. ¬†“I definitely think something’s wrong,” Sargent said. “The DNA isn’t even back yet, and I don’t understand it, and the DA can’t even tell me, they don’t even know anything, and they’re the ones who dropped it.” Gates’ bond is now set at $250.
