Abstract:
A body was discovered associated with a series of bloodstains on a sunken loading ramp of a supermarket. The initial evaluation of the scene by the local police determined that the victim was crushed by the rear wheels of an 18-wheel grocery truck when it backed down the ramp for a delivery. However, a careful examination of the photographs of the scene and the victim revealed that the victim was deal and in rigor mortis before the truck entered the ramp. The truck's rear wheels never came into contact with the deceased. The truck interacted with the decreased and his bicycle to create series of unusual bloodstain patterns.

Fixation and Sectioning
The simplest type of preparation is the wet mount, in which the specimen is placed in a drop of liquid on the slide. A liquid specimen can be directly deposited on the slide using a dropper. Solid specimens, such as skin scraping, can be placed on the slide before adding a drop of liquid to prepare the wet mount. Sometimes the liquid is simply water, but stains are often added...
