Following are some of the transmissions from Friday morning:

• "They're saying somebody's shooting in the auditorium."
• "They're saying there's just hundreds of people running around."
• "Somebody's spraying gas in there, too."
• "Need more officers inside theater nine."
• "We got another person outside shot in the leg, a female. I got people running out of the theater ..."
• "Another victim on the north side of the theater in the parking lot."
• "We need gas masks."
• "I'm being told that he's in theater nine."
• "Get out some d**n gas masks for theater nine. We can't get in it."
• "We have a party in car shot."
• "I need at least three or four ambulances brought in here."
• "I need a marked car behind the theater ... the suspect in the gas mask."
• "Set up a perimeter around the entire mall."
• "We need rescue inside the auditorium. Multiple victims."
• "Seven down in theater nine."
• "Shooter might be wearing a white and blue plaid shirt."

At this time, police began dispatching help from surrounding police departments, including Denver.
