Spontaneous combustion of a person. In 1951, 67-year-old Mary Reaser was found dead in her apartment. The courier could not get Mary to open the door and asked his neighbor how to get to the apartment. Nothing in the apartment seemed strange, except that in one corner was a pile of ash and a woman’s foot. Operatives did not find any signs of hacking. The experts who investigated the case said that it is possible to turn a person into a pile of ashes only at a burning temperature of 3000 degrees for several hours. But how can the fire in the apartment burn without touching anything but a woman? The investigation has not progressed further than guesswork.
