I absolutely think he's wearing a backpack. Early on in the investigation it was mentioned in reference to BG's description, I'm fairly certain, but I'll have to do some digging in the media thread to find it.
It's always looked to me like he's got some type of duffle bag slung over his shoulderI think it's quite large. At first I could have swore his left hand was up by his face because he was carrying a bag over his shoulder. The flesh colored spots that are supposed to be his hands just don't look natural. I really feel these images have been altered in that area to conceal something only the killer would know (like an unusual weapon, etc...)
The way his hands are supposedly in his pockets is what I can't wrap my head around. Why is one hand down so much lower than the other?? I understand they would shift up/down a little as you took a step with your opposite foot, but his left hand is down so low in every picture! I just can't find my self to buy these pictures at face value implying that his hands are in his pockets. No one looks like that when they walk with their hands in their pockets! Unless he's got like a cargo pant with multiple pocketssome high, some low.
