dr. vincent dimaio. as jurors took notes, dr. di maio laid out his findings that george zimmerman suffered six impact injuries to his face and head. and that while the gun was against trayvon martin's sweatshirt when the trigger was pulled, the sweatshirt was 2 to 4 inches away from his body, consistent with someone leaning over another person, as zimmerman described to investigators. >> the medical evidence, the gunshot wound, is consistent with his opinion -- with his statement as to that. >> during cross-examination, demayo agreed that martin could have been pulling away when he was shot and that bruises from a fight could take days to appear or not appear at all. >> in other words, george zimmerman could have hit trayvon martin and not left any bruising on his knuckles. >> that's correct. >> legal analysts say the doctor was a strong witness for the defense. >> dr. di maio was most effective in his cross-examination. he was calm, he understood the questions. he didn't give an answer when questions seemed to implicate a differ

dr. vincent dimaio says zimmerman's testimony is consistent with the story. the gun powder burns showed trayvon martin was over zimmerman when he shot and killed the teenager. inches away. it's consistent with somebody leaning over the person doing the shooting. >> reporter: that is how zimmerman describes events to the police after the shooting. >> i shot him. i didn't think i sit him. he sat up and said, oop, you got me. >> reporter: he said he could have lived three minutes after he was shot and could move his arms under his body after zimmerman had spread them out. the defense is trying to convince jurors zimmerman acted in self-defense but the prosecution says the testimony didn't prove who started the fight that led to martin's death. the state also argued the victim could have been backing up when he was shot. >> with zimmerman on the ground and he would have this same angle. he's pulling away and zimmerman's shooting him at that time. >> yes. >> the prosecution got de-mayo to admit he's being paid $400 an hour for his defense but forensic consultant m

dr. vincent dimaio took one big point at the prosecution's case and that's where was the muzzle of the gun was shot to death because if trayvon martin was on top of george zimmerman it could have been very different than if trayvon martin were on the bottom and george zimmerman was doing that mma beatdown. >> forget what george zimmerman had to say. forget what the prosecution has to say. listen to the science. the science tells it all. forget everything else. it tells you there was a separation between the gunshot and the body. we know that the gunshot penetrated the clothing and then entered the body. >> two to four inches separation between the clothing and the actual skin. >>. >> the natural inclination that the bullet will go but that's a minor point. the most important point is the nature of the defect of the clothing and tattooing. if you lean over somebody you notice that the clothing tends to fall away from the chest. if instead you're lying on your back and somebody shoots you the clothing is going to be against your chest. the fact that we know the clothing was two to four inche

dr. vincent dimaio has 40 years of experience as a forensic pathologist, charges $400 an hour. on the stand today the doctor said forensic evidence shows how the barrel of the gun came into direct contact with trayvon martin's clothing about it was two to four inches away from his skin or body. in other words, trayvon martin was likely leaning over george zimmerman with gravity pulling his hoodie towards the ground. >> if you lean over somebody, you will notice that the clothing tends to fall away from the chest. if instead you're lying on your back and somebody shoots you, the clothing is going to be intense your chest. >> the defense expert says this does not appear to be a straight-on shot. that contradicts the prosecution's case. the doctor appears to support zimmerman's claims that he was engaged in a struggle at the time. but under cross-examination he acknowledged that he could not say who threw the first punch or even whether there was a first punch. the doctor is a veteran of the u.s. army medical corps. he is a former chief medical examiner in san antonio. he is a for

dr. vincent dimaio, a pathologist, who seemed to back up george zimmerman's argument that trayvon martinshot him. here he is. >> the wound itself by the gap, by the powder tattooing in the face of contact of the clothing indicates that this is consistent with mr. zimmerman's account that he -- that mr. martin was over him leaning forward at the time he was shot. >> brian: there is an eyewitness who said it was trayvon martin on top and he was the closest to the actual scene. so here is what it means. if trayvon martin was on top pounding his head into the pavement, he did look to have a broken nose and cuts on the back of his head even though a doctor did testify these aren't life-threatening wounds. could you feel as though your life was being threatened if you're on the bottom? is it reasonable to say that you had no choice at the time to take out a gun? >> gretchen: that's why it would be so important to know who was actually screaming on the 911 call. that's indecisive because you had the parents of trayvon martin who said it was their son who had those blood curdling screams in that
