Why the gunman opened fire is still not known, but in the early morning hours a gunman opened fire on a crowd of people at a midnight showing of 'The Dark Knight Rises.' Fourteen people died and another 50 were injured.

Witnesses say that the suspect was wearing a bullet proof vest and a helmet. Before opening the fire, the suspect threw what appeared to be a gas canister filling the theater with smoke.

Police believe that the suspect that they have in custody acted alone but no motive has been given.
