In response to the unexpected paucity of blood/tissue spatter at the site where a body of an adult woman was dismembered by an electric chainsaw, we dismembered two large pig carcasses with a small electric chainsaw in a controlled environment. These experiments demonstrated first that a large carcass could be easily dismembered by a small electric chainsaw. When the chainsaw bar is held parallel to the ground the majority of the blood and tissue is deposited directly beneath the saw and bar and very little elsewhere. If the discharge chute of the saw however is not oriented directly at the ground, larger amounts of blood and tissue may 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 bony surfaces cut by a chainsaw.
针对一名成年女性尸体被电锯肢解现场出现的意外少量血液/组织飞溅情况，我们在可控环境下用电锯肢解了两头大型猪的尸体。这些实验首先表明，小型电锯可以轻松肢解大型尸体。当电锯锯条与地面平行时，大部分血液和组织会直接沉积在锯条下方，其他地方很少。然而，如果电锯的出料口没有直接对准地面，大量的血液和组织可能会喷到侧面或沉积在离电锯一定距离的地方。电锯切割木材时在木材表面产生的特征性条纹，在电锯切割骨头表面时也能发现。
