UPDATE (7:10 p.m. EST):

As of now, it's unclear how many victims there are.

Witnesses recounted what took place (via the Denver Post):

“He didn’t say sh**,” said one of them, who spoke on the condition of anonymity. “He just came in and started shooting.”
The other witness said the gunman “let off a couple of shots, then was silent, and then he let off a couple more. He wasn’t spraying.”
The two men were able to escape out the back of the store.

Others said they made their way out of the building and helped others to do the same.
