A Hempstead man faces as many as 25 years to life in prison after he was convicted Wednesday of fatally shooting a man outside a night club in 2011, Nassau prosecutors said.

A jury found Michael Gibson, 35, guilty on all three indictment counts: second-degree murder and two felony charges of second-degree criminal possession of a weapon. His sentencing is scheduled for July 16.

His attorney, Joseph Lo Piccolo of Garden City, said an appeal is being planned because his client denies being the shooter and was not there Sept. 3, 2011, when a 23-year-old man was shot in the neck outside the Seduccion night club in Hempstead.

"We believe reasonable doubt was present throughout the case," Lo Piccolo said, raising concerns about witness statements and DNA test results.

According to prosecutors, Gibson drove past the club about 3 a.m. and saw his friends and a group of men outside fighting. He parked down the block, ran to the fight and fired once into the group, hitting the 23-year-old man in the neck, authorities said.

Gibson fled to North Carolina, where Nassau homicide detectives and New York State parole officers arrested him in December 2011.

"This defendant stopped his car, approached a bar fight with a gun drawn, shot and killed a man, then tried to run from his crime," acting District Attorney Madeline Singas said in a statement, adding that Gibson will be "held accountable for this senseless violence."

Lo Piccolo cast doubt on testimony from a key witness, and DNA results from the gun, dumped in a Uniondale storm drain, saying at least three people's DNA were found on the gun.
