• Resumen

  • In response to the unexpected paucity of blood ⁄ tis sue spatter at the site where a body of an adult woman was dismembered by anelectric chainsaw, we dismembered two large pig carcasses with a small electric chainsaw in a controlled environment. These experiments demon-strated first that a large carcass could be easily dismembered by a small electric chainsaw. When the chainsaw bar is held parallel to the ground themajority 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 isnot oriented directly at the ground, larger amounts of blood and tissue may be sprayed on lateral surfaces or deposited some distance from the chain-saw. 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
