The results rule out Martin's DNA from being on the gun's grip. Zimmerman's DNA also was identified on the gun's holster, but no determination could be made as to whether Martin's DNA was on the gun's holster, according to the report from the Florida Department of Law Enforcement.
Zimmerman is charged with second-degree murder for fatally shooting Martin during a confrontation in a gated community in Sanford in February. Zimmerman is pleading not guilty, claiming self-defense.
A delay in Zimmerman's arrest led to nationwide protests.
The question of whose DNA is on the gun and holster could play a role in Zimmerman's defense.
Zimmerman says Martin had been on top of him, slamming his head against the ground and smothering his mouth and nose with his hand and arm when he grabbed his gun from a holster on his waist before Martin could get it. He shot the teenager once in the chest.
Prosecutors could argue that the lack of DNA means there's no evidence on the gun of a struggle, or that Zimmerman can't claim self defense.
