Recognition of lightning-induced trauma to the skeleton: A forensic taphonomic study

Lightning related deaths can be hard to recognize in most circumstances, unless explicitly looked for, and impossible when the remains are fully skeletonized. There is a crucial need for this for forensic authorities in South Africa, where there is a high incidence of lightning deaths and a high rate of recovery of unidentified bodies in the skeletonized state. The effects of a 15 kA, 8/20 μs impulse current applied to a series of pig femurs was investigated as well as a comparison with a skeletal element from a giraffe struck by lightning. A distinct pattern of traumatization was observed and is described in detail. Further analysis and comparison to human results should be carried out and a method for accurately identifying lightning related fatalities should be created.
