I vote for fentanyl.
My first thought exactly. It takes an extremely small amount to kill you. I recall a story about a deputy who nearly died just from inhaling vapors off a stash he found in a suspect's vehicle.
Virtually certain it is fentanyl.

That would be false. There’s a lot of hysterical syncope involved when LE meets up with a drug scene.
