Lichtenberg Figures

Lichtenberg figures may  appear on the skin of lightning strike victims. These are reddish, fernlike patterns that may persist for hours or days. They are also a useful indicator for medical examiners when determining the cause of death.  Lichtenberg figures appearing on people are sometimes called lightning flowers, and  are thought to be caused by the rupture of small capillaries under the skin due to the passage of the lightning current or the shock wave from the lightning discharge as it flashes over the skin.
