Dr. Murray left the voicemail at 11:54 AM.
TMZ broke the true timeline story -- that Dr. Murray called his girlfriend from Houston at 12:03 PM the day Jackson died -- 9 minutes after he left the voicemail for Russell.
Sources tell TMZ the girlfriend told cops ... approximately 5 minutes into the call, Dr. Murray abruptly dropped the phone and she then heard him administering CPR. Dr. Murray never came back to the phone and the call ended at 12:13 PM.
Jackson's bodyguard called 911 at 12:21 PM, approximately 13 minutes after Dr. Murray dropped the phone.
