shelby: old, over weight and has amnesia. And can still go in and kick ass halo style. dont be discouraged old people. you can still be badass like shelby
I only sayd hints that require investagation to find out.You must want to find out who it is if you found out.If you found out that means that you wanted to know who it is so don't blame me.
Another hint.He is one of the charecters you play with.Blake isnt one of those so he can't be the killer.You also saw that he is bit overweight from the episode 13 I think and these facts should leed you to who he is.
I will have to give you guys a hint.The son of that old lady still has a coat with the same colour that he had in preveous episodes where they showed what happened.
