no, sir. they told the court part of the course he talk covered the practical application of self-defense laws with a special focus on florida laws like stand your ground. and zimmerman aced the class. he was probably one of the better students in the class. zimmerman s defense team argued his past training and education had no relevance to this case. next prosecutors called amy see ward, a firearms expert with the florida department of law enforcement. he testified through tests on trayvon martin s clothes she was able to determine it was a contact shot that killed him. it is consistent with the muzzle of the firearm touching the outer sweatshirt and the inner sweatshirt being in direct contact with the outer one, yes, sir. the final witness, anthony goregone, a crime lab analyst that examined dna samples on all of the evidence in the case. attorneys focused on the question of whose dna was found on zimmerman s gun. you were able to exclude
the swab from the pistol grip of the defendant s gun was positive for blood, correct? yes. and then there was a mixture, the major matched the defendant george zimmerman? yes. and you were able to exclude trayvon martin as having dna on the pistol grip, correct? yes, trayvon martin was excluded from being a possible mixture. reporter: the hoodie was tested saying zimmerman s gun was actually touching the fabric when he fired the fatal shot. what did you find distance-wise when you conducted the test with the sweatshirt. it is consistent with a contact shot. so again, evidence saying that the end of the gun was against the material when it was fired? yes. the prosecution also pointed out the night he killed martin,
she s looking at gunshot residue, burned and unburned particles, and the tearing and singeing of the fibers around the hall. the conclusion makes sense to me that it was a contact shot. what s mysterious is that the autopsy report indicate not that it was a close shot or contact shot, but rather it was an intermediate distance shot which tellses me it was probably between six and 18 inches. who is likely to be more accurate? i would tend to think that the ballistics expert is more accurate because that bullet had to penetrate both garments before it hit the body. you wouldn t necessarily see the stipelling which is the burning and the abrasions in the skin around the hole, the bullet hole and therefore, if you see those stipelling mark, sometimes called tattooing then you can conclude the distance. does it really matter, the distance in this? it doesn t because both would
