A tape recording, which has emerged online, is believed to feature a Los Angeles Fire Department medical worker calling the UCLA hospital, reports the Sun.
A voice on the tape says: “Patient is michael jackson, the pop star singer. No pulse, no breathing. Unresponsive. Tried to resuscitate him. Unsuccessful. We've done everything we can. We should be there in five minutes. It doesn't look good. It doesn't look good".
The tape emerged on an ambulance workers' web forum but has yet to be confirmed as genuine. An LAFD spokesman said of the recording: "I couldn't confirm that is one of our workers. It could be. They refer to 'pop star michael jackson' but it is not our practice to name names."
If genuine, the tape could be used in Dr Conrad Murray's involuntary manslaughter trial later this year as it contradicts his claims the star was still warm and had a pulse when he found Jackson and put him in the ambulance.
