Gun found in Will Smith's car, but no evidence it was fired

— -- NEW ORLEANS - A fully-loaded 9-millimeter handgun was found inside Will Smith's vehicle on the night he was killed, according to the New Orleans Police Department.

No ballistic evidence or shell casings were recovered to show that the weapon was fired, according to a news release by the NOPD. The NOPD did not specify whether there was any indication that Smith ever held the weapon during the incident.

The attorney for Smith's alleged shooter, Cardell Hayes, suggested Monday that he believed the discovery of a second gun on the scene would help prove his client was not guilty of second-degree murder. Although the attorney, John Fuller, would not specify if he planned to claim self defense, he said his client was not the instigator and felt threatened.

The NOPD also revealed that it found a fully-loaded revolver inside Hayes' vehicle. There were also no shell casings or ballistic evidence recovered to show that weapon was fired.

Police said previously that all shell casings on the scene matched a third weapon, the .45 caliber handgun that was recovered on the scene and was believed to be in Hayes' possession during the time of the shooting.
