Annotation: This paper describes the blood and tissue spatter pattern and tool marks on bone and skin from dismembering a large pig carcass with a chainsaw.
Abstract: This experiment was conducted after investigators unexpectedly found relatively little blood/tissue spatter at the site where an adult woman's body was dismembered by an electric chainsaw. The experiment involved the dismemberment of two large pig carcasses with a small electric chainsaw in a controlled environment. The experiment found that a large carcass could be easily dismembered by a small electric chainsaw. When the chainsaw bar was held parallel to the ground, the majority of the blood and tissue was deposited directly beneath the saw and bar, with very little found elsewhere; however, if the discharge chute of the saw was not oriented directly at the ground, larger amounts of blood and tissue might be sprayed on lateral surfaces or deposited some distance from the chainsaw. The characteristic striations created on the surface of wood as it is cut by a chainsaw can also be found on body surfaces cut by a chainsaw. 13 figures and 5 references
