In a video interview, the eyewitness explained to 9 News Denver
that, based on the way the crisis unfolded, the shooter had help inside the theater.
"From what we saw, he wasn't alone," the survivor said, referring to the masked gunman. "He had someone with him, because the second can of tear gas didn't come from his side."
"We can only assume that someone got [the shooter] in, because whatever he was wearing seemed thick," the eyewitness added. "I think he would stand out in a crowd."
Although Aurora Police Chief Dan Oates told CNN
that that there was no evidence of a second gunman at the scene, the Atlantic
is reporting that law enforcement is still trying to determine if the shooter acted alone.
