Damn you guys! I was JUST about to post the whole "dude with address" thing and BAM!
SOOOOO, he/it couldn't have been a maller. Like somone said before, they'd have wiped that spot clean as hell. I'm thinking he/it came with some cleaners while the Mallers backtracked. They popped him/it and since he was infected, didn't bother with the body.
He/it has to be one of her old crew. Maybe they'll bring it up when she asks "How the hell did you find me anyway?" and they'll take her back to view the body.

The theory about Chinwe being Corrections is a sound one. I think that's why there were so many files on them.
Anyone think that Chenwe is back at Tower 1?
