Spontaneous Human Combustion
***
Spontaneous human combustion (SHC) describes alleged cases of the burning of a living human body without an apparent external source of ignition. While there have been about 200 cited cases[1] worldwide over a period of around 300 years, most of the alleged cases are characterized by the lack of a thorough investigation, or rely heavily on hearsay and oral testimony. In many of the more recent cases, where photographic evidence is available, it is alleged that there was an external source of heat present (often cigarettes), and nothing occurred "spontaneously."
Many hypotheses attempt explanations for the various cases of human spontaneous combustion. These generally fall into three groups:
-Paranormal explanations (e.g., a ghost or divine intervention)
-Natural explanations based on an unknown and otherwise unobserved phenomenon (e.g., production of abnormally concentrated gas or raised levels of blood alcohol cause spontaneous ignition)
-Natural explanations that involve an external source of ignition (e.g., the victim dropped a cigarette)
Objections to natural explanations typically refer to the degree of burning of the body with respect to its surroundings. Indeed, one of the common markers of a case of SHC is that the body—or part of it—suffered an extraordinarily large degree of burning, with surroundings or lower limbs comparatively undamaged.[1]

24th March, 1997
Co Kerry, Irish Republic. 76 year old John O'Connor was found dead in his living room at Gortaleen by the community nurse who regularly visited him. Mr O'Connors charred remains were in a chair positioned some distance from his hearth. Only his head and upper torso along with his feet remained unburnt. There was little smoke damage to the room or furniture. The Local priest who attended the scene described it as "if somebody had poured petrol into his lap".

One such instance is the combustion of a knight named Polonus Vorstius sometime during the reign of Queen Bona Sforza in Milan (sometime between 1515 and 1557) [2] In the Sixteenth Century, the Academic Senate of Copenhagen was sent a deposition about a person who died after belching flames, and then being consumed from the inside. (Historiarum Anatomicarum Rariorum by Thomas Bartholin).

Dr. Mark Benecke, a forensic scientist as well as a biologist, says no. In his article, Spontaneous human combustion: thoughts of a forensic biologist (Skeptical Inquirer, 1998) he writes, "To my knowledge, no scientific book or article written by a chemist, physicist, biologist, or doctor has ever reported bodies suddenly igniting through some internal but unknown mechanism."
He also asserts that unlike common belief in complete annihilation of the body, in alleged cases of SHC, the internal organs of the victim are usually not "essentially changed" and that in all cases, the internal organs suffer no more damage than the body's exterior, which indicates the fire begins from outside rather than from within.

Unverified natural phenomena
- Since every human body contains varying strengths of electrical field and the human body also contains flammable gases (mainly methane in the intestines), an electrical discharge could ignite these gases.
- SHC victims are sometimes described as lonely people who fall into a trance immediately before their incineration. Heymer[3] suggests that a psychosomatic process in such emotionally-distressed people can trigger off a chain reaction by reacting nitrogen within the body and setting off a chain reaction of mitochondrial explosions. This hypothesis has been criticized on the basis that Heymer "...seems to be under the illusion that nitrogen exist as gases in the blood and are thus vulnerable to ignition, which is, in fact, not the case."[4] (Mitochondria are organelles found within cells.) The hypothesis also fails to take into account the fact that nitrogen is an inert, non-flammable gas.
- Another hypothesis suggests high-energy particles or gamma rays[1] coupled with susceptibilities in the potential victim (e.g. increased alcohol in the blood) triggers the initial reaction. This process may use no external oxygen to spread throughout the body, since it may not be an oxidation-reduction reaction. However, no reaction mechanism has been proposed, nor has a source for the high-energy particles.
- The victim is an alcoholic and has been smoking while drinking or shortly after drinking a strong spirit. There are claims that this raises the blood alcohol level to a point where it ignites; however, this theory is implausible, since ethanol typically burns only if the concentration is greater than about 23%, whereas a fatally toxic level is about 1%.[5] However, this does introduce the probability that the victim falls asleep while holding a lit cigarette.
- Another hypothesis is that both clothing and the person are ignited by a static electric discharge. A person walking across a carpet can build up sufficient charge and voltage to create a spark. It is unlikely that this could start a clothing fire, as although the voltage can be high (several thousand volts), the stored energy is very low (typically less than a joule). Proponents of this hypothesis say that records show there has never been a recorded case of a naked SHC victim.
- The controversial phenomenon of ball lightning has also been proposed as a cause of spontaneous combustion.
- One hypothesis for SHC takes into account mitochondria, the "internal combustion engine" of higher living organisms.
Mitochondria are the powerhouses of the body, and sites of highly active energy packet production that uses an oxidative phosphorylation mechanism. Uncoupling of the metabolic processes in mitochondria from its energy production results in generation of large amounts of heat that is called thermogenesis. (This heat production is different from fever, which is an inflammatory response to infection).
Mitochondria are especially abundant in the skeletal muscle cells that require high energy output for their function. Since skeletal muscles constitute a major portion of the body, they harbor an enormous number of energy producing mitochondria. Under stress and certain extreme physiological conditions, the hyperactivity of energy producing mechanism of the body may exceed the conservation or utilization.
Available body fat may also serve as additional fuel for combustion. This hypothesis still requires rigorous laboratory testing.
Natural Explainations
- Cigarettes are often seen as the source of fire. Usually, it is thought that natural causes such as heart attacks may lead to the victim dying, subsequently dropping the cigarette. Embers from cigarettes and pipes may also ignite clothes.[3] Additionally, cigarettes burn at a temperature too low to trigger a flare up of most otherwise combustible materials. Typically, a lit cigarette dropped on an article of clothing creates a burn-hole, but does not initiate an open flame and spread.
- The "wick effect" hypothesis suggests that a small external flame source, such as a burning cigarette, chars the clothing of the victim at a location, splitting the skin and releasing subcutaneous fat, which is in turn absorbed into the burned clothing, acting as a wick. This combustion can continue for as long as the fuel is available. This hypothesis has been successfully tested with animal tissue (pig) and is consistent with evidence recovered from cases of human combustion.
- Scalding can cause burn-like injuries, including death, without setting fire to clothing. Although not applicable in cases where the body is charred and burnt, this has been suggested as a cause in at least one claimed SHC-like event.
Murder Most Foul
In March of 2000 at a forensic science conference held in Australia, US scientist John De Haan stated his belief that murder is often involved in alleged SHC occurrences. He explained that an external accelerant generates sufficient heat to sit a body ablaze and melting body fats continue the conflagration after the accelerant has been expended3.
Haan backed up his theory with an experiment he had conducted in a controlled environment. The layer of fat under the skin promotes burning9. Because they are similar to humans in fat content, Haan chose a dead pig as his victim. He wrapped the pig in a blanket, wetted the blanket with a small amount of gasoline and then set it on fire. After five hours, Haan's experiment showed that the pig remains were identical to those found in spontaneous human combustion cases4.

The Subatomic Pyrotron Theory, which is based on quantum physics. The theory states that there is an extremely small but high-powered particle—like a neutrino—that zips through the spaces between the quarks that make up the atoms, which compose the molecules of the human body. On rare occasions a rogue particle scores a direct hit with a quark and sets off an internal chain reaction. I’ve dubbed this occurrence the Internal Hiroshima Effect, which may result in SHC.

Apparently Spontanious Human Combustion has been pretty much solved, heard this years ago - thats why it's not a hot topic anymore:
1) an external ignition source such as a lit cigarette dropped into flammable clothing
2) this burns through to the fat layer where the ‘wick effect’ takes place.
3)Fat from the body is soaked into the victim’s clothing - who is passed out - it then burns like a candle.
Human fat burns at very high temperatures
But my question is with human fat burns at high tempretures, why is everthing else intact?
You can see the fat on the chair where it has melted - why did this not catch?
- I think an almost instant incineration is the only way nothing else could burn. I think the theory of the hydrogen combusting in our water molecules (which make up most of our body) is the theory I would lean most towards believing.edit on 9-4-2011 by byteshertz because: (no reason given)

Yeah the SP theory is fairly new to me and was only something i heard about today. The link i provided isnt exactly a science link but similar to all the others....
I tried searching for that theory on Google but could only come up with fringe sites... I am not saying it is not possible, just that i couldnt find anything to back it up. I tried to though and it may be possible.
If you find anything on it please post
In regard to people being awake, there is a report on the first youtube clip i posted about something related whilst the lady was awake.
There are also survivors of clamied SHC events, i actually meant to add it in to the OP under the vicitms section but forgot and then by the time i remebered the 4 hours had past
Two examples of people surviving static flash events are given in a book on SHC.[9] The author, John Heymer claims that the two subjects, Debbie Clark and Susan Motteshead, speaking independently and with no knowledge of each other, give similar histories.[10] In addition, Jack Angel claims to have survived an SHC-like event:
In September 1985, Debbie Clark was walking home when she noticed an occasional flash of blue light.[11] As she claimed, "It was me. I was lighting up the driveway every couple of steps. As we got into the garden I thought it was funny at that point. I was walking around in circles saying: 'look at this, mum, look!' She started screaming and my brother came to the door and started screaming and shouting 'Have you never heard of spontaneous human combustion?'" Her mother, Dianne Clark, responded: "I screamed at her to get her shoes off and it [the flashes] kept going so I hassled her through and got her into the bath. I thought that the bath is wired to earth. It was a blue light you know what they call electric blue. She thought it was fun, she was laughing."
In winter 1980, Cheshire, England resident Susan Motteshead was standing in her kitchen, wearing flame-resistant pajamas, when she was suddenly engulfed in a short-lived fire that seemed to have ignited the fluff on her clothing but burned out before it could set anything properly alight

the wick theory is back engineered, it is all wrong. takes way too much time.
i've read and seen almost everything about SP for decades.
i will go with the first responders gut, that this is not biz as usual.

Have you people ever considered the possibility that these victims are beings from another starworld who came to live amongst earthlings. This could be their way of dying. There has been no more reports of such happenings since the last one.Speculations of the cause of the burning does not hold their weight because of the peculiarity of the burned body.It has the looks of a cold type of fire that does not cause the surroundings to catch fire.
