Blood And Tissue Spatter Associated With Chainsaw Dismemberment Summary

Good Essays
In the article “Blood and Tissue Spatter Associated with Chainsaw Dismemberment” author Brad Randall discussed the dismemberment of two large pig carcasses by a small electric chainsaw in order to study the patterns of blood and tissue spatter. Although there was no blood present in the basement where the body was dismembered, there were small pieces of bone and soft tissue discovered with DNA that confirmed that it was in fact the missing 43-year-old woman who had been murdered and dismembered there. The few pieces of bone and soft tissues had been recovered from the adjacent walls no more than 1 m above the floor, as stated by the article. When the case was being investigated, there were speculations about the weapon used to dismember the victim because the body was large in size and the small space in…show more content…
The electric chainsaw produced a significant amount of blood and tissue when cutting into the pig carcass when it was held at a parallel angle. The blood and soft tissue, however, were located under the discharge chute and underneath the chainsaw. There was a no evidence of spatter found on the sheet walls more than 1 m above the floor of this experiment, which was similar to the crime scene. In opposition, when the chainsaw was held in a vertical position there were larger amounts of blood and soft tissue spatter on the walls. When the chainsaw is held as a horizontal angle, the discharge is downward, while there is more of a lateral discharge when the chainsaw is held at a vertical angle. This concludes that the suspect must have positioned the chainsaw at a parallel angle in order to achieve fewer spatter on the lateral walls. Of course, the amount of blood and soft tissue that is spattered on the walls is also determined by the amount of post-mortem days the body has at the time of
