If a gun with a silencer is fired, killing someone, and a bullet casing is left on the floor, other than eyewitness testimony, would police be able to prove a silencer was used? Or could that be a fact kept with the killer?

I’m definitely not an expert, but the casing most likely wouldn’t be impacted physically by a suppressor / silencer however the bullet itself is…my understanding is that it makes it much more difficult, if not impossible, to match the bullet back to the gun that shot (in comparison to a gun & bullet without a silencer).

When the bullet leaves the chamber it then travels through the barrel of the gun, which typically leaves consistent / similar markings due to the rifling (& size shape etc) of the barrel that can then be matched to other bullets fired from the same weapon. When a suppressor / silencer is added to the equation though, it damages and/or removes those markings, and creates additional new ones that are much less matchable / traceable than those from the barrel / gun itself.

Modern / high quality ones should not affect the bullet itself, however those used in crimes are often homemade / diy units which can be much less precise, causing the bullet to sort of ‘bounce around’ inside of the silencer resulting in inconsistent markings that would be difficult if not impossible to match back to a specific gun.
