He was dead on arrival, shot in the heart.
Statistically speaking, traumas that arrest prior to medical personnel arrival (EMS or ED) have near as make no difference zero chance of survival. Standard practice is to stop external bleeds, intubate, place bilateral chest tubes (or bilateral finger thoracostomies), have given one round of ACLS drugs, and call it if there is no progress in rhythm. If those measures do not save them their injuries are to profound to survive. This has been studied in trauma centers for decades, and nobody has yet to find a better solution.
Thoracotomy, clam shells, and sternotomy have very little benefit in the ED, and are almost always a futile effort (there are some very rare times that they do help, but are not likely to help if they are not going directly to the OR anyway).
I thing that TNCC is a great idea, it's a great beginners class for trauma.
