I guess it depends on how he did it. Carbon monoxide poisoning will not leave the same kind of mark as a gunshot. I accidentally bought a BMW 2002 at a donor lot many years ago that the owner had killed himself in by gunshot. It was not disclosed, of course. There was a pool of half-dried blood soaking the carpet and floor behind the drivers seat. My dog found it first. Nastiest clean-up job ever.
