Weather Turns Witness in Forensic Meteorology

It's a rainy day in Southern California, and, as a mystery fanatic cozy indoors with a good who-done-it, it started me thinking about weather and murder--and the interesting role of "forensic meteorology" in investigations. I'm clearly not alone because The Weather Channel debuted its own true-crime series "Storm of Suspicion" last year, highlighting the role played by weather science in solving murders. For example, in one case, a husband claims that his wife was murdered, and he was knocked unconscious, by an intruder. Yet forensic meteorological analysis showed the lawn around the house would have been so soggy with dew at the time of the murder that an intruder would have left clear footprints. Lack of any footprints helped clinch the husband's arrest. In another case, footprints betrayed a murder-as-accident scheme: A woman is found dead at the wheel of her crashed SUV after apparently skidding off an icy road--until footprints in the snow are spotted walking away from the wreck. Yet another example hinges on lack of snow: An accused murderer claims he sustained a scratch on his hand while snowboarding and not during the attack--only it was raining at the time of the alleged snowboarding, melting a slight snowpack and leaving slopes too bare for the sport. The weather is such a common factor in tragic events that forensic meteorologists have been used as expert witnesses in murders, suicides, bombings, vehicle accidents, bad aircraft landings, property insurance disputes, hurricane and flood damage claims, building collapses, slip-and-fall insurance scams, and much more. Unfortunately, as global warming leads to more extreme and dangerous weather events, forensic meteorologists will be keeping busy!
