Faced with such a mystery, the St. Petersburg authorities called in the FBI. Laboratory findings showed that Mrs. Reeser's estimated weight of 175 lbs. had been reduced to a total of _less than 10 lbs._, including the foot and shrunken head. The final report concluded that no known chemical agents or other accelerants had been involved in starting the fire. Dr. Krogman has burned cadavers with gasoline, oil, wood, and all kinds of other agents. He has experimented with bones encases in flesh or stripped, both moist and dry. His tests have utilized combustion apparatus ranging from outdoor pyres to the most modern pressurized crematorium equipment. He has demonstrated conclusively that it takes extraordinary heat to consume a body, and that only at over 3000 degrees Fahrenheit would bone become volatile enough to lose its shape and leave only ashes. "These are very great heats", he said, "that would sear, char, scorch or otherwise mar or effect anything and everything within a considerable radius." Another mystery was the slippered left foot, which Mrs. Reeser, having been in some discomfort, was in the habit of propping up on a stool. The foot was left unburned, apparently because it was outside the mysterious four-foot radius of incineration. Perhaps strangest of all, and unique to this case of SHC, was the shrunken skull. Dr. Krogman commented: ...the head is not left complete in ordinary burning cases. Certainly it does NOT shrivel or symmetrically reduce to a smaller size. In presence of heat sufficient to destroy soft tissues, the skull would literally explode in many pieces. I...have never known any exception to this rule. ______________________________________________________________________________ SEE: Michael Harrison, "Fire From Heaven" Vincent Gaddis, "Mysterious Fires and Lights" Francis Hitching, "The Mysterious World: An Atlas of the Unexplained" Frank Edwards, "Stranger than Science" Reader's Digest, "Mysteries of the Unexplained"
