Most cases of (human) spontaneous combustion rarely 100% of the body
(to my knowledge) there is always some bones and tissue left.
However there was such a case where combustion was 100% complete I
should imagine it would be possible
to work out the approximate size of the combustee by examining the amount
of debris (ie: minerals and ash) that remained.
Recent advances in forensic PCR (which can get a DNA finger print from
a single cell), suggests that a DNA profile can be obtained merely from
swabbing down and PCR'ing surfaces that bare skin may have come into
contact with.. I don t h ave a refference for this .. it was on a TV
documentary about forensic pathology (Bit too late for OJ's gloves on this one)
Hence, examination of the environment in which the remains were found
might give further clues.
