A White Plains judge handed down the maximum sentence Wednesday for a Yonkers gang leader convicted of an execution-style murder.

Carlton Byrd was convicted of second-degree murder for shooting Kaream Foreman in October 2005. Police say the two men had an argument prior to the shooting. Foreman was shot in the back of the head after turning away from Byrd. Foreman?s family members expressed relief at the sentencing.

Byrd?s lawyer insists that his client had an alibi with several witnesses to his whereabouts at the time of the shooting. He plans to file an appeal.
