"We have no evidence of a second gunman but obviously we are concerned about that."Police found the gunman out the back of the cinemas in possession of a gas mask and a rifle and a hand gun.
"There was another weapon in the theatre."
Perhaps this is why there is some confusion about the number of shooters.
So, still some conflicting reports there.
7:09pm: Moviegoer Hayden Miller says the assailant was wearing a gas mask and throwing tear gas.He says the gunman did not want to let anybody out.
"We heard 10 to 20 shots... and then management came on the PA system and put the fire alarm on and said everyone had to get out.
"As soon as we heard the shots go off, we figured it must have been a louder part of the movie next to us.
"This is a potential terrorist attack - I am at a loss for words."
