You don't care much about that if you use ie 10-shot .22 revolver. You can't suppress it that well though. The other thing is, revolver doesn't leave empty shell around (unless you intentionally throw it away at that place when reloading). Which is good for assassins, but if in this case shell was found (not familiar with the case) then its probably not this.
