I am sorry to hear that B.H. I really dont know your friend situation, but similar issue happened to my uncle in a city called Bradford U.K on March 2003. On that particular day, he was getting ready to go back home in order to get married. So he withdrew all his savings from the bank, got his luggage ready. He was burnt to death, using gas and matches. However only his head and chest got burnt. He was found setting down on a chair (Is that possible??). Its impossible to remain in your seat (in the basement) and commit suicide without falling to the ground. The police said he commit suicide to close the case, but all the evidence shows that it was clearly murder... There are many examples of him ''muslims'' where their cases was simply closed and labelled as suicide, where in fact it was murder.....
sorry I got carried away.. Inshallah be patience B.H.,
wa la howla wa la qowata ila billah.

Sorry to hear about your uncle's death. May Allaah swt grant him Jannah. You mentioned only his head and chest got burned. I've watched a program long time ago about "Human Combustion" where a person gets burned without any cause.
Spontaneous human combustion or SHC is referred to burning of human body due to production of excessive heat in the body. The heat produced has been argued to be possibly dut to some chemical or nuclear reaction in the body.
