Abstract

We developed a scene depicting blunt force trauma to an individual’s bones that were burned. We burned a skeletonized femur from a domestic pig (Sus domesticus) in a control and secondary pit. In the control nothing was done to alter the femur prior to burning. The bone in the secondary pit was hit with a hammer to simulate blunt force to the distal end. The bones in the two pits burned for one hour. We then extinguished the fire with water to mimic rain. We examined bone shrinkage, color changes, and signs of blunt force trauma and compared the two femora. The findings indicate that there is no noticeable difference between the two femora that would differentiate between changes induced by blunt force trauma and those due to solely fire.
