(CNN)  -- Michael Jackson's personal chef Kai Chase says June 25 was shaping up as another typical day in the superstar's usually peaceful and orderly home until an urgent plea from Jackson's personal doctor sent panic sweeping through the household.



Michael Jackson's personal chef Kai Chase appeared on CNN's "Larry King Live" Thursday night.



In an interview with CNN's Larry King that aired Thursday night, Chase described the chaotic events that fateful day and what life was like inside the Jackson family before the singer's shocking death.



Chase said she was downstairs preparing lunch for Jackson -- being sure to wrap it in Saran wrap because the singer liked his meals served room-service style -- when Dr. Conrad Murray called out for her. Murray is the central focus of a federal investigation into the singer's death, a law enforcement official told CNN on Wednesday.



Around noon or a little after, Chase said, "Dr. Murray comes down the stairs. There was a stairwell that leads into the kitchen. And he's screaming: Hurry! Go get Prince. Call security. Get Prince."



Chase said she quickly got Jackson's oldest son.



"Within minutes, the paramedics are there. And the security is running upstairs, skipping stairs and all of a sudden we're all, you know, panicked," Chase told King. "So the energy in the house had just kind of changed from that happy kind of day that we were having and preparing lunch and having a good time to just kind of eerie."

Chase said Jackson's daughter, Paris, started crying and calling out for her father as people in the home came to realize how serious the medical situation was.



"We started crying and we all come together in unity in a circle and we started holding hands. And we started praying," Chase said.



The chef said she was not allowed into the upstairs quarters of the home, but she had seen Michael Jackson downstairs on Wednesday, June 24. Nothing she saw the day before cause her alarm.



"He ate lunch with his children at the dinner table. And then I packed ... his dinner for him to go to his rehearsal. He seemed like he was just, you know, tired," Chase said. She attributed the way he felt to his long rehearsals.



Chase said Jackson did complain once about his demanding schedule.



"The third day I was there, when I came back, he had told me, 'You know, they're killing me. They're killing me because I'm working too much. I'm rehearsing too much.' "



Between 1 and 1:30 p.m. June 25, Chase said security asked her to leave the home, and she never saw Michael Jackson being transported to the hospital. She didn't learn of Jackson's death until later that day on the radio.



Chase said that Murray was in the house often in June and she attributed the doctor's frequent presence to Jackson's rigorous rehearsal schedule for an upcoming series of concerts in London, England.



Search warrants filed Thursday in court in Clark County, Nevada, and carried out at Murray's offices imply that investigators looking into his death believe the singer was a drug addict.



In his interview with Chase, King pressed for details of evidence of drug use by Jackson:



King: Did you notice oxygen tanks, because if it was Diprivan and they have to measure ... your blood pressure? They also need oxygen tanks if you're giving that drug. Did you notice them?



Chase: I saw the oxygen tanks, yes.



King: Where were they?



Chase: I would see Dr. Murray carrying the oxygen tanks down in the mornings.



King: On that morning or other mornings?



Chase: No. I didn't see him that morning. I saw him in the afternoon, but other mornings.



King: He would carry them down?



Chase: Carry them down.



King: They were portable oxygen tanks?
