AUBURN — A Maine man is going to jail for 30 days for hitting a man with his car, in what police say was payback for a fatal accident five years ago.

In a plea agreement, 22-year-old William Panzino, of Auburn, pleaded guilty to reckless conduct and driving to endanger Wednesday in Androscoggin County Superior Court. He was originally charged with aggravated assault and reckless conduct with a dangerous weapon.

The Sun Journal of Lewiston said Panzino was charged with striking Kyle Karkos on an Auburn street last June, sending him to the hospital with cuts and bruises. Panzino said it was an accident.

But prosecutors said Panzino ran down Karkos as retribution for a 2006 crash that killed a passenger in a car driven by Karkos, who was then 17.
