Which means he isn't a sniper/assassin, he's a traditional assassin.

How about an injection knife? maybe some sort of dust based dagger, blade heats up to cauterize the wound, into the heart or brain stem, instant kill with no blood splatter.

Quick, clean, effective. Combine it with a silenced pistol and add lockpicks to his kit, you're good to go.
