If you were going to take this in bad faith, I'm surprised that you considered "3 people died in car accident this morning" to be reporting. If you wanted to be pedantic about it, stick only to the facts, and avoid speculation/opinion, it'd have to be written like so:
"A person who our reporter spoke with who went by the name of Bob Dylan and claimed to be the coroner of James County, said that three individuals passed away recently, and he said he believes that they died due injuries similar to those involved in car accidents. Our reporter also asked the James County Sherriff's Department to corroborate, and a person who claimed to be the spokesperson for the James County Sherriff's department said that there were three individuals in a car accident last night, and they were taken to the hospital."
Anyways, I wasn't trying to write a rigorous example for each, I assumed that the reader could fill in the detailed. I just aimed to give the gist of what it should look like. You'd talk to experts, cite papers, etc.
