If someone has a likely deadly injury in my home in the wee hours, I'm not sure that I would call 911 except from the car. I know that if one of my kids was hurt badly I absolutely would not wait for an ambulance, for example. I'd take them to the hospital myself. I might call a neighbor, too. I might not. Idk if his motives for calling the neighbor first were pure, but I wouldn't say it's completely unfathomable if your goal is to get the injured person to the hospital asap rather than wait. You'd want someone to help you, including in the car. Idk how long it takes to get an ambulance in SA or how far the hospital was from his house, though.
