I think it takes a doctor to pronounce the person deceased, which is why so many victims are categorized DOA.
My neighbor's teenage son hanged himself. Even though there was nothing they could do, the EMTs still had to hook him up to respiration and monitoring equipment on the gurney as they wheeled him to the ambulance -- moving at a slow, careful pace. They left without sirens.
The woman left the scene and was later arrested for “collisions involving substantial bodily injury,” officials said.
Technically, she had no way of knowing if he was still alive, so once the threat was stopped -- i.e. he was unconscious -- she was supposed to stop and call 911. I don't believe she's required to render aid on the spot, just remain until police and medical help arrive.
I was an alternate on a jury hearing a case of road rage. From the stories told, the two had been cutting each other off for a few miles in heavy traffic. At some point, the traffic caused a standstill. That's when one driver got out, went to the driver's window of the other car, and reached in to fight the driver.
The charges were assault, battery and unauthorized entry into a vehicle. I got a call from the clerk letting me know I was off the hook as an alternate, and that the jury found the defendant not guilty. The verdict shocked me because there were witnesses that said they saw the assault. i guess they just wrote it off as two dueling dumbasses getting into a scrape with no significant injuries worthy of incarceration. I wish they allowed alternates to observe the deliberations and vote results. I'm very curious what the members said about the facts.
So, even if she has to go to trial, there's a good chance she'll be acquitted. Hopefully she'll be spared any charges when the investigation is done.
