Michael Jackson's personal chef Kai Chase revealed details about the role of Jackson's doctor Conrad Murray amid investigations surrounding the physician linked to the death of the King of the Pop.

Chase, a chef hired by Jackson to cook healthy food for himself and his children, told the Associated Press in an interview that Dr. Murray used to come to Jackson's home at night - around 9 p.m. or 9:30 p.m. - and go to the singer's room.

When Chase left home sometimes late night, she wouldn't see the doctor leave and understood he was staying the night. Early mornings when she came for work, she describes seeing Murray coming down the stairs with oxygen tanks.

In the morning of June 25, when Jackson died, Chase recalls not seeing Murray come down the stairs in the morning as usual which made her think Jackson was sleeping late. She also recalls that she began to prepare the lunch and around 12:05 or 12:10 she saw Murray coming down the steps and screaming very loud Go get Prince (the oldest son of Jackson), the news agency reports.

I walked into the hall and I saw the children there. The daughter was crying. I saw paramedics running up the stairs, Chase told the Associated Press.

Chase began to pray with the children and their nanny and a housekeeper and recalls everyone became very quiet. Chase and other house's staff were asked to leave the house because the singer was being taken to the hospital.

A law enforcement official participating in the singer's death investigation told the Associated Press that Murray regularly administered the drug propofol to Jackson to help him sleep. Investigators are working under the theory that the drug caused Jackson’s heart to stop, according to AP. Murray is now the target of a manslaughter investigation, according to the report.
