He might as well have pulled the trigger himself.

Donnell Flora, 27, (pictured below) was sentenced to 100 years in prison on Monday after he was found guilty of charges including first-degree murder in the April 28, 2014, slaying of Endia Martin (pictured above).

Not only did the Chicago man — who is paralyzed from the waist down from a 2010 shooting — provide his niece with the murder weapon, but he also accompanied her to the shooting.

The spat between the teen girls escalated after the victim posted death threats on social media over a boy. Flora’s niece, whose name has not been released, showed her uncle the threats, so he felt it was necessary that she bring protection with her when she went to confront Martin and her best friend, Lanekia Reynolds.

“It was never supposed to go the way it went,” Flora said in court. “I wish I could trade places with this young lady, but I can’t.”

Assistant State’s Attorney Athena Farmakis said, “He did the unthinkable.”

Flora’s niece was charged as a juvenile and is awaiting trial in juvenile court, but could be released when she’s 21 if convicted.
