Yes? Lol
The prognosis for someone receiving CPR after an unwitnessed arrest is abysmal for a much younger, healthy person - like 5% chance of survival and even less than that for survival without severe brain damage. If they performed CPR correctly they broke every rib in his chest, and if they were somehow able to get his heart beating again then he's certainly on a ventilator and brain dead. The absolute "best case" scenario is that the family is in denial and they haven't decided to pull the plug yet.
