En 1951, Mary Reeser, une femme de 67 ans est retrouvée en partie calcinée. Seule sa jambe avec son pied encore chaussé est retrouvé à côté d'un tas de cendre et de graisse. La légende raconte qu'elle aurait pris feu sans aucune raison. Mais est-ce que c'est possible ?

00:00 A pile of ashes on the ground, human fat and a spitting leg, still on the floor.
00:04 This horror scene is real and I'll explain what happened.
00:07 To get there, this woman, Marie Rieser, would have burned from the inside, like that, for no reason,
00:12 leaving only a few pieces of her body on the spot.
00:15 This phenomenon is called spontaneous combustion, or self-combustion, and it's far from being the only case to be assessed.
00:20 Drs. Virvée Colliounen and Nicolas Klüger from the University of Helsinki
00:23 have also analyzed 12 self-combustion cases, most of which in France.
00:27 What is observed is that the victim's body burns despite the absence of a heat source around the body.
00:32 He would then inflame like that, from the inside, without explanation,
00:35 leaving only fat, ashes and a few limbs like legs and arms.
00:39 The reason is unknown, and for good reason, it would be a legend.
00:43 Well yeah, physically, we can't justify why it happens spontaneously,
00:47 so maybe, quite simply, what happens is not what we think.
00:50 Among all the cases assessed, many of the victims were smokers.
00:53 Dr. Christian Palmier, from the Roman University Medical Center of Geneva,
00:57 explains that we would have a phenomenon similar to that of the candle.
01:01 Basically, the victim dies, for example of a heart attack.
01:03 The cigarette she was smoking falls on her, her clothes catch fire, burns her skin and reaches the fat.
01:08 We then have the clothes that act as wick, and the fat that acts as wax.
01:12 The fat then flows down, little by little, maintaining the combustion process.
01:15 And the fattest parts of the body are therefore the calcined ones.
01:18 The cigarette butt is also calcined in history, so we think there is no heat source initially.
01:22 But the explanation of the candle remains a theory, and research on the subject is still limited,
01:27 but it is in any case much more credible than a spontaneous combustion.
