A New Hampshire man who was convicted of assaulting police officers says he is a changed man after having served 16 years in prison, and has asked a judge for early release.

According to WMUR-TV, ex-boxer Richard Edson violently attacked Deputy Judy Estes in 2003 while she was attempting to arrest him for driving while intoxicated. He was sentenced to 22 to 60 years behind bars.

Prior to that incident, Edson was sentenced to three to seven years in prison for deliberately running over former police Officer Tom Drouin with a motorcycle, injuring Drouin's leg so badly it ended his law enforcement career.

Several former corrections officers have written letters in support of Edson's release, saying that he has had a clean prison record.

Edson's victims oppose any early release.

The judge has yet to rule on the matter.
