The personal chef to the late Michael Jackson, Douglas B. Jones, disclosed to RadarOnline his experiences with Jackson's physician Dr. Conrad Murray.

Jones told the Web site that Dr. Murray was at the house five nights a week and says he noticed some peculiar behavior. "There were occasions where I noticed during my term of employment in the security mobile unit that was located in the driveway that there was a few oxygen tanks there as well," he told Radar.

As the Associated Press previously reported, police found Diprivan at Jackson's house. Radar notes that medical literature states this powerful sedative is not for home use and should always be used with oxygen.

Jones continued, "I noticed Dr. Murray exiting the kitchen area through the side door to the driveway area carrying a couple of oxygen tanks. ... The oxygen tanks were waist high, from my height. Heavy duty tanks."

The chef referred to Jackson as thin and moving very slowly prior to his upcoming tour. "I don't think he's going to survive this concert tour," Jones remembered telling his family.
