Miranda is one. Biggest hint is the TARDIS. Daniel is 2. Biggest hint is Thor. Amanda is 3. Biggest hint is Fonz. Which just leaves Tor as 4. It's process of elimination. Trust me, I use that often with my crime shows. If Tor would murder the others, It would be kinda easy to find him as the unsub.
