Just googled a bit but didn't find anything about ''kill room'', a pig farm and/or an anesthesiologist. Before quitting on my Pizzagate research, I had found a Toms Creek but didn't pursue much in that direction.

It's near Fort Detrick.

If you find it again, I'm still interested to read what the info is about.
