1 heat. Local standard time, as filed.
An Alorton man was found dead in his home. The County Coroner ruled the cause of death as heat exhaustion. The temperature inside the house was well over 100 degrees. High temperatures on the 17th and 18th were in the lower to middle 90s with the Heat Index around 100.
As the offices recorded each death: direct deaths were caused by the weather itself, indirect ones by something it set in motion.
