a .38-caliber weapon. there were two torso shots. one of those torso shots, the bullet remained. the other torso shot, the bullet went all the way through his body. in the yard, investigators found the projectile that passed through shaw s body. this, along with the two bullets found inside shaw s body were sent to the forensics lab. under a microscope, firearms expert chris henderson discovered that the lands and grooves on two bullets were the same. the third bullet was different. we determined that we had two different shooters, based on the class characteristics of the bullets. in their search for potential suspects, police had to consider whether rosana shaw had anything to do with her husband s murder. ron s grown son from his first marriage certainly thought so.
who had prior arrests for petty theft and burglary. a suspect happened to be wearing spalding tennis shoes like we had told the investigators that they were looking for. since these are spaldings and we already know that we need spaldings, we needed to have these analyzed right away because this could be the big break in audrey s shooting. police sent the shoes to the forensics lab, where they were inked and printed. using transparent overlays, amy michaud compared them to the two partial prints found in audrey nichols home. that was compared directly to the photograph of the footwear impression on the linoleum and then directly to the glass. michaud was looking for two things class characteristics, which result from how the shoe is made, and accidental characteristics, which result from how it s worn. just the random wear that occurs to the bottoms of those shoes through ordinary activities every day, it

these shots. first of all, it had to be a semi-automatic to leave shell casings. they re going to reveal a lot about the manufacturer of the gun. what type of ammunition was it. there are going to be class characteristics and individual characteristics on both the shell cings and the bullets. so there s a lot of information there in the evidence. but obviously, once you have a gun, you will be able to tell if that gun fired those bullets. also trajectories. people saw the muzzle flash and so they do have a fairly good idea of trajectories. when all this comes together, even without a gun, if this gun had been used in other crimes, it could very well be sitting on a data base, the ammunition that is. that will give you a possible linkage to previous crimes that have been committed with a gun. but that s speculation. we don t know. is it the strieuations on the actual casings itself or the
