Murder Trial and Murder - Case Study Example The Circumstantial evidence that could be deduced was that of Massachusetts State Police chemist Deanna Dygan who in her testimony in the superior court held up the floral underpants of the Rachel stated that blood samples and sperm cells were found in the crotch area. However seminal fluid could not be tested positive. Further, the shirt of Rachel which was covered with blood was found to have sperm cells and three holes out of which two had tested positive to lead which is present due to a gunshot. Finally, it was found that the death of the infant had been caused due to a contact shot. The circumstantial evidence which had been put forward by Dylan was said to be inconclusive and thus was of not much help. The objectivity of the investigation was put into question by the lawyer of Elliot Weinstein who put in the relevant evidence that is if prior to or during the investigation Dylan had put in Entwistle’s name in the suspect box on crime scene sheet. Dylan stated in the affirmative on which Elliot stated that this had affected the investigation procedure. Further, he argued that the bullet wound had not been found at the crime scene and had been found during the autopsy, a vital element not noticed during the investigation of the crime scene. Finally when Weinstein asked if the bullet trajectory had been carried out which was answered in the negative by Dylan. The relevant evidence which had been established in the specific case led to the establishment of the fact that Dylan had been led to believe that Neil Entwistle the possible suspect was the culprit. and so a biased opinion had been possibly established by the chemist. The direct evidence that was provided was that by Drugan, the senior chemist in the state police crime lab's arson and explosives unit who stated that the residue of gun primer was found only on the hands of Rachel. He went on to say that quite a few items of the BMW had been tested at the airport and it was deduced that neither the steering wheel, keys and a shirt had all been found to be negative when the tests for the gun primer had been carried out. Further eleven knives had been tested for the knife block but all came negative. The direct evidence that had been provided for by Drugan was in itself a bit inconclusive which led to a stronger case being established for the possible suspect. Further the items that had been tested had strengthened the case of the husband of Rachel. The testimonial evidence was provided by Trooper Stephen Walsh who is a member of the fire arms identification unit. He provided that he had tested a bullet which had been removed from the body of the victim Rachel's chest and had further removed two fragments of bullets.
