vincent dimaio, an expert in high velocity gunshot wounds, testified for the defense. >> the absence of blood on the handguns, you don't find blood on the muzzle. it's a little more common in shotguns. but don't forget with rifles and, in this situation, you had clothing in between. >> dr. dimaio also believes the autopsy photos clearly show ernestine was shot in the stomach. >> when you discharge a gun, off the muzzle of the gun comes up flame that's about 14 to 1500 degrees. and out comes gas and out comes soot, carbon from burning gunpowder. if you put the muzzle of the gun against the body, then you're going to have this soot and the flame burns and then the effects of gas. if you look at the wound in the abdomen, there's soot and there's flame burns. that means the muzzle was in contact with the body at the time of discharge, therefore, this has to be the entrance. >> and dr. dimaio says the gas discharge from the rifle temporarily inflated ernestine's abdomen with enough force that it ripped her jeans, contrary to the prosecution's claim that they were torn during a fight. last
