Who do you think killed Faith and Snow?
Here's what i think happen, i think Dee killed Faith (If you choose to go to Toad's Apartment first, he beats up Toad looking for info on Faith. When he finds out Toad doesn't have any, he threatens to kill his son. And goes to Lawrence's to seek info. Arriving there, he tries to get something out of him, but when he reveals that Faith is dead, he gets motivated to suicide, then he kills himself.
A minute later Wolf enters the apartament, and Dee tries to hide, for obvious reasons. Then Wolf finds him, and chases Dee. When you finally get him, on the conversation, he mentions Faith's death, but no one saw her head except for Snow and Wolf, and they move it right after Snow shows it to Wolf, so the only way he knew about this is seeing it before Snow arrives, because if he saw it when Snow was heading to Wolf's apartment, he probably would've investigated or called someone and not just staring at it.
And i think Snow's killer was Dum. Just notice that only Dee enters the Trip-Trap, without Dum. So while Dee's at the bar, Dum kills Snow. That's my theory, what's yours? Who do you think killed Snow and Faith?
Ps; Sorry for the bad english, i'm don't speak fluent english :P
