tubuh manusia sebagian besar terdiri dari air tetapi disebutkan ada fenomena yang disebut spontaneous human combustion. korbannya disebutkan kebanyakan adalah peminum alkohol berat dan penderita obesitas. bisa jadi karena sifat alkohol yang mudah terbakar dan lemak juga bisa jadi bahan bakar. ada beberapa kisah mengenai korban SHC:
On April 9, 1744, Grace Pett, 60, an alcoholic residing in Ipswich England, was found on the floor by her daughter like "a log of wood consumed by a fire, without apparent flame." Nearby clothing was undamaged.
In 1951the Mary Reeser case recaptured the public interest in Spontaneous Human Combustion. Mrs. Reeser, 67, was found in her apartment on the morning of July 2, 1951, reduced to a pile of ashes, a skull, and a completely undamaged left foot.
On May 18, 1957, Anna Martin, 68, of West Philadelphia, Pennsylvania, was found incinerated, leaving only her shoes and a portion of her torso. The medical examiner estimated that temperatures must have reached 1,700 to 2,000 degrees, yet newspapers two feet away were found intact.
On December 5, 1966, the ashes of Dr. J. Irving Bentley, 92, of Coudersport, Pennsylvania, were discovered by a meter reader. Dr. Bentley's body apparently ignited while he was in the bathroom and burned a 2-1/2-by-3-foot hole through the flooring, with only a portion of one leg remaining intact. Nearby paint was unscorched.
On July 1, 1951, in St. Petersburg, Florida, Mary Hardy Reeser, a 67-year-old widow, spontaneously combusted while sitting in her easy chair. The next morning, her next door neighbor tried the doorknob, found it hot to the touch and went for help. She returned to find Mrs. Reeser, or what was left of her, in a blackened circle four feet in diameter.
All that remained of the 175-pound woman and her chair was a few blackened seat springs, a section of her backbone, a shrunken skull the size of a baseball, and one foot encased in a black stain slipper just beyond the four-foot circle. Plus about 10 pounds of ashes.
