A Mansfield man's legal gamble came up "snake eyes", and he ends-up with an extra year in prison.

Joshua Dunham pleaded guilty to Aggravated Vehicular Homicide and Aggravated Vehicular Assault in an accident in which one man was killed and another seriously injured.

Prosecutors say Dunham was driving his SUV drunk, when he rammed into the rear of a motorcycle, with Aaron Kessler as the driver and Mason Volkmer the passenger.

The impact caused Volkmer to fly 180 feet through the air and hit a telephone pole, killing him.  

Dunham was sentenced to nine years in prison, but it was overturned on appeal.

Assistant Richland County Prosecutor Gary Bishop says Dunham elected to stand trial, was convicted, and this time sentenced to 10 years in prison.

Aaron Kessler spent months recovering from his injuries, only to be killed in another accident.
