STAMFORD — A drunken driver who caused a motorcyclist to sustain permanent brain damage in a hit-and-run accident will spend four years in jail.

Luna-Perez, a Guatemalan national, pleaded guilty in August to second-degree assault with a motor vehicle, leaving the scene of an accident and drunk driving.

Luna-Perez, a welder who has been in the U.S. for eight years, agreed to be sentenced to up to four years in prison.

The accident occurred when Kemp was traveling south on West Avenue on his Suzuki 750 just before 9:30 p.m. on June 5, 2015. Luna-Perez, heading in the opposite direction, made a left turn right in front of him, police said.

After striking Kemp, who was wearing a helmet at the time of the accident, Luna-Perez kept driving on Baxter Avenue, police said.

One witness gave police the license plate of the car that fled the accident scene. Police tracked the car down a short distance away where they found Luna-Perez, who admitted to having six beers an hour before.

“He feels he is being punished and held captive in this facility and his mother Jenny feels helpless because she can not take care of him at home,” Mother’s Against Drunk Driving victim advocate Michelle Chamberlain wrote in a letter.

“The Kemp family is thankful that Willard survived the crash, but his injuries are life altering and he will never be the same,” Chambelain said.

He was sentenced this week to four years in jail and five years probation. The judge also gave him a six-year suspended sentence, which he could be made to serve if he violates probation following his release.
