ORLANDO, Fla. -- Forensic tests made public Wednesday show that George
Zimmerman's was the only DNA that could be identified on the grip of
the gun used to fatally shoot 17-year-old Trayvon Martin.

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.


Looks like no "struggle for the gun" argument to be made.

You've been watching too many TV shows.

Yes, and furthermore no struggle for the gun is necessary for
Zimmerman to have felt "threatened" although it would certainly help
his defense.
