Yes, like a recording studio or a rehearsal room. Hmmmm.
The ONLY reason I shy away from this theory is because I'm pretty sure Steven wouldn't be the only victim of someone who went to such great lengths to hide what they were doing. Now, if they can tie any other missing people to SCA somehow, that would be worth looking into.
I really have to wonder if they've even tried....
Carbuff and I spent about a week trying -- and DID come up with one: the guy, about two miles away in SCA, whose wife saw him walk out the door and get into a car.
If anyone wants to read about it, scroll down to the bottom of the timeline page - and click on "similar cases".
Carbuff did a LOT of good research there!
