A Troy man was sentenced Monday to 31 years in prison for shooting a woman who spurned him on Valentine’s Day 2010.

A jury in January convicted Karon McFarland of the Feb. 14, 2010 shooting of Averil Hall that left the 29-year-old mother with permanent facial injuries.

She did not address the court, but the prosecutor did.

Assistant District Attorney Peter Willis said Hall was shot multiple times in the face by McFarland, who was jealous that she hung out with other guys.

“”This was four shots, some of which connected, and which changed her life forever,”” Willis said. The shooting has affected her hearing, sight and her ability to care for her son and to work, and McFarland’s refusal to accept responsibility for his crime makes him a danger to society, the prosecutor said.

Visiting Judge Michael V. Coccoma referred to a presentencing report in which a probation officer described McFarland as “”pleasant.”” The judge wondered out loud how that same man could have nearly killed Hall.

“”I think you have a Jekyll-and-Hyde personality insofar as it relates to Ms. Hall,”” Coccoma said. “”It’s unfortunate that your young life will be interrupted by a significant prison sentence.””

McFarland turned down a 91/2-year plea deal. A Schenectady County Court jury then convicted him of assault, burglary and weapons possession. He was acquitted of attempted murder.

Defense attorney Cheryl F. Coleman reminded the court that her client had no previous criminal history and that his tough upbringing may have affected his actions.

McFarland expressed remorse and wished Hall well in her recovery in a statement he read in court.

“”I was a law-abiding citizen who helped the elderly and was a role model to kids and my nieces and nephews,”” he said as his family and Hall listened in the gallery.
