c is the first letter, because in CRASH the s can't be the hit as proven before. it can't be r because of BRATS. And it can't be a because of BRATS again. that leaves C or H. but patch has no hits. thus, it must be c.
EDIT: Sorry, illogical guess.
BRATS
BRAID
If BRATS = 0 then since only last two letters were changed, it must be t or s. But, since FIRES was 0, then we can rule out the s. thus, we can reason that I was the first hit.
"Hey guys, I just had a vision! some guy just suggested we take the pesticide book and farming techniques book! I don't know about you, but I trust this guy." Flame swims back to the books and awkwardly takes pesticides and goes back toward the exit, ready to leave at a moment's notice.
definitely get some form of protection now or later. That note doesn't look good. Check the body, turn it over, basically do a through examination of the body. Then call the police officer for the tree thing.
Is it just me or does the victim have the same description as ourselves? Could the Zodiac Gangs want to kill us? (Sorry, stupid question but I had to ask.) Anyways, investigate the scratches.
