At 5:30, Elvis' daytime Cook, Nancy Rooks, tells what happened on August 16, 1977, around 2:00 p.m. (this is from her book and/or an interview): "... with the hollering they were doing *they just knew Elvis was gone*. So by then I was trying to get in touch with Dr. Nichopoulos. *I called him on every phone he had, but I didn't get any answer*. So his Auntie was going to get her doctor out there, but he said 'No, he is not my patient'. So by that time somebody called the ambulance and, somehow, they got in touch with Elvis's doctor." "So the ambulance was not called right away?" "No, it wasn't." "When they brought him down, he looked like he was asleep *with blue spots on his face*". Nancy said she *heard a loud noise upstairs around 9:30 a.m.* "But I just thought they were into it" (i.e. having an argument, like earlier). https://www.youtube.com/watch?v=MR2CFZ7WuGA
Elvis' nurse Marian Cocke in 1975-77, who also worked at the Baptist Hospital, at 1:35: "They said that Elvis was in the Emergency Room." "So I went down there, they were working on him, and I asked them to stop. *Because it was SO evident he had been gone A LONG TIME*." Commentator:"And with that, doctors pronounced Elvis Presley dead at 3:30 p.m. central time in the Baptist Hospital E.R." in the video entitled "Elvis' Nurse Says Goodbye" - https://www.youtube.com/watch?v=6MOxteMFdnM

At 15:25, 1) Dr Noel Florendo: a) "No gross evidence of a heart attack", b) "Elvis Presley most probably died of the interaction of several drugs, i.e. polypharmacy."; at 17:45 "codeine, morphine, quaalude, valium, valmid, placidyl, nembutal, phenobarbital, pentobarbital & butabarbital" ("all downers, i.e. central nervous system depressants, several of which are addictive") were found in Elvis' dead body; and at 18:10 "The contents of his stomach were pumped out & destroyed, although they are well-known KEY elements to analyze the cause of death!" in "The Elvis Cover-Up 1979" - https://www.youtube.com/watch?v=lyKWLmi3wPo "
