'We need to call an ambulance,' you speak over Anthony's hysterics. 'He might still be alive.'
Anthony stops for a moment. 'Might? I gave him a bullet to the neck! He isn't going to live. I've got this under control.'
Kyle steps towards him. 'The old man has neighbors, Anthony. Neighbors who are incredibly likely to call the cops because of your damn gunshot. Call an ambulance, and run.'
Anthony raises his gun. You recall having six bullets to spread among the three of you; he spent one on the old man, and has one left.
'Shut up!' he shouts, 'I've got this under control. We don't need an ambulance! We take what we need, then scram. Now put your guns on the goddamn ground!'
