1 heat. Local standard time, as filed.
An 88 year old woman was found dead in her home, the apparent cause of death heat exhaustion. Two window fans and an air conditioning unit were not being used. A thermometer in the house registered 106 degrees.
As the offices recorded each death: direct deaths were caused by the weather itself, indirect ones by something it set in motion.
