A witness statement from a paramedic says Dr. Conrad Murray - who is accused of the involuntary manslaughter of Michael Jackson - told emergency services the late star was ''fine'' when they arrived on the scene.
Michael Jackson's personal physician told people the star was "fine" when he laid dead, court papers claim.
Paramedic Richard Senneff - who was the first person on the scene when emergency services were called to the singer in June 2009 - revealed in his statement that Dr. Conrad Murray stood in front of his patient's lifeless body and claimed there was not a problem.
According to the statement, the medic said: "He doesn't have a problem. He is fine.
"He was practising all night. I'm just treating him for dehydration."
Documents obtained by the Daily Mirror newspaper also reveal Richard believed the doctor - who is due to stand trial for the involuntary manslaughter of the star after being accused of administering the lethal dose of the anaesthetic Propofol that killed him - lied about the medications Michael was taking.
When asked if he had taken anything, Murray replied: "No, he is not taking anything," but the statement records him as admitting seconds later that he had administered the 'Thriller' star with anti-anxiety drug lorazepam "to help him sleep".
In his statement, Richard also said he later saw the doctor clearing bottles from the room, and claimed he found Murray administering CPR on the bed, despite 911 operators having instructed him to move the singer's lifeless body to the floor before carrying out the resuscitation attempt.
The trial is due to begin next week.
If convicted, the doctor faces up to four years in prison.
