So I have a soon to be brother-in-law that got a dui, well several... He was placed on parole and doing fine. His girlfriend pressed charges on him after he broke up with her for Attempted Murder, saying he tried to choke her. She then dropped the charges after she realized how long he would be in jail. He was never proven guilty or stated he was guilty, but apparently violated his parole.

Is that even a possible way to violate parole>?
