On the 911 tape obtained by TMZ, one of Jackson's staffers tells the dispatcher that Jackson is "on the bed" and that a "doctor is here." The doctor is Dr. Conrad Murray.
Several EMTs tell us it's odd that a veteran cardiologist like Murray would attempt CPR while Jackson was on a bed.
Common CPR practices call for the patient to be on a hard surface -- because it is difficult to compress the chest on a soft surface. The 911 operator told the staffer to "get him on the floor."
Cops have yet to officially interview Dr. Murray, but this will almost certainly come up.
