1990, September: Hurstpierpoint Fiery Death
In September 1990 in Hurstpierpoint, Sussex, England, a 34-year-old man was discovered dead in his bedroom with severe burns to his arms and legs, as well as "other parts of his body." It was speculated that a five-day-old bonfire in the garden was somehow connected with the death.
This is the first listing of this incident in Anomalies, and therefore will require more research to confirm it. This is especially true because the above comes from Jenny Randles and Peter Hough's 1992 book, Spontaneous Human Combustion; this book gives almost no sources for the accounts it relates, in this case attributing it to "Author's own investigation"... which essentially means "Just trust us." For this reason, this account is marked as both "Unreliable" and "Investigate;" I will add new information as I get a chance to dig further; though it doesn't sound very mysterious if the man died of external burns and there was a fire outside he could have been in contact with. More details are required to even infere anything supernatural in this case.
