The autopsies state that identifying a mushroomed bullet that contacted bone was difficult and that it appeared to be approximately .40 caliber. It also could've been a 10mm as they are very close in diameter.
The posters point was that there was no mention of a firearm found at the scene to identify the round that caused the death. His final point is, "How does a dead person dispose of a firearm used to commit suicide?"
I hope you aren't considering a career in forensics.
