A harrowing recording of the emergency services initial radio response to the Denver shooting has revealed how officers were desperately trying to save the lives of victims in the chaotic aftermath.
The radio call starts off with the operator telling the units: 'They are saying there is hundreds of people just running around.'
As the gravity of the situation becomes clear the operator urgently demands: 'All units respond to the theatre.'
As she relays information to the officers about the shooting in theatre 9, they begin to radio in news of victims they are discovering.
One officer says: 'Somebody is spraying gas in here too' in reference to the smoke grenade James Holmes, 24, threw into the packed theatre before opening fire.
Another officer radios in: 'I got another person shot here female, I got people running out the theatre.
Concern about the gas is evident when an officer asks: 'Do we have gas mask available?'
The operator responds: 'Can any units bring gas masks to theatre 9? We need gas masks.' Again a panicked voice is heard saying: 'We can't get in the theatre. We need gas masks.'
Officers outside the building then radio in about finding a suspect.
'I need a marked car behind the theatre...suspect in a gas mask,' says one officer and states that the suspect's car is white and in the rear car park.
Another responds: 'Yes we got rifles, gas mask, he's detained right now.'
A decision is made to move all the victims to the north end of the theatre as a perimeter is set up around the building.
Screams can be heard in the background when one officer says: 'I got two victims of the east side north side of the theatre - I need an ambulance real quick.'
Several officers start radioing in asking for medical assistance and the frustration can be heard when one person says 'I got one ambulance - where my ambulances at?
As the chaos continues, with hundreds of people running around, an officer says: 'I am taking one male to hospital in my car.'
