weekends, depositions at night. reporter: most of this final day in the defense case focused on the testimony of an expert on the use of force. if you haven t been able to successfully win the event in the first 30 seconds, you need to change tactics. reporter: who said zimmerman had no other options but to shoot trayvon martin because he wasn t adept at fighting and felt his life was being threatened by the teen. zimmerman has pleaded not guilty to second-degree murder saying he fired in self-defense. i don t know what else he could have done based on his abilities because, not to be offensive to mr. zimmerman, he doesn t seem to have any. reporter: under cross-examinati cross-examination, prosecutor john guy used a foam dummy to question where zimmerman s gun was located when he pulled it. if this mannequin were carrying a firearm on their waist where would the gun be in relation to me? would be at your left inner thigh. right here, right? yes. reporter: later

well, it was all too much for him. he left the courtroom in tears. zimmerman s gun. he said martin reached for it during the altercation, but does the evidence match up? latent fingerprint expert kristen benson. did you find any latent prints of value on state s 183? no. you mentioned environmental effects can have a negative effect on latent prints, correct? yes, it can damage latent print. i think you mentioned rain itself can? it can. a map of the neighborhood where it happened, orienting the jurors to the scene. who was where, and when were they there, and the blood-stained hoodie. the sweatshirt that martin was wearing on the night that would be his very last. it s certainly become an icon. does the forensic evidence show that shirt was pressed up against martin s chest, or hanging down when he was shot? the difference could show whether or not martin was on top
