CHICAGO (WLS) --Donell Flora learned his fate for providing a gun to his niece, who allegedly used it to kill 14-year-old Endia Martin.
Flora was sentenced to 100 years in prison.
Earlier this year, Flora, 27, was found guilty on three counts - first-degree murder of Martin, as well as attempted first-degree murder and aggravated battery with a firearm involving another teen who was the intended target.
Flora's now-16-year-old niece is awaiting trial on murder charges in juvenile court. The niece, who remains unnamed because of her age, asked her uncle for a gun to take to a fight.
Flora supplied the gun used in the 2014 murder and accompanied his niece to the shooting in the 900 block of West Garfield, prosecutors said.
Flora claimed he was trying to protect his niece when he gave her the gun. Prosecutors said that if he had not provided the gun, Martin would still be alive today.
