FACT: Dzhokhar Tsarnaev did not have is backpack on when he was running away

There are some people look this photo:

and claim to see that Dzhokar still has his backpack. He is not wearing a backpack. He is wearing an un-buttoned jacket with a hooded sweater. His left hand is clearly visibly not holding a backpack, and his right arm (blocked by the woman with sunglasses) is in a position of a person running with a normal gait and carrying nothing.

There is no backpack in this photo. He placed it at the foot of Forum restaurant and left it there. It then exploded moments later, killing three people.
