THE doctor quizzed over the death of Michael Jackson may have botched the only chance to save the dying superstar.

Police in LA are already investigating whether Conrad Murray administered a fatal drugs jab that caused Jackson's heart to fail.

But experts last night claimed the 911 emergency call from Jackson's home reveals potentially fatal blunders as he fought to save his celebrity patient. Police have been in contact with Murray, who could not be traced in the hours after Jackson died, and expect to interview him within days.

They will quiz him about the daily injections of morphine-like Demerol administered to the singer who was dependent on a cocktail of eight powerful drugs. But it has emerged they also want to discuss his doomed attempts to save the star. Detectives were due to begin quizzing Dr Murray at midnight last night but his lawyer Matt Alford denies he is a suspect. He said that the police were piecing together a timeline of the events, not conducting a criminal probe.

The tape of the 911 call, made at 12.21pm on Thursday, reveals CPR - aimed at restarting Jackson's heart - may have been botched. Pressure The star should have been laid on the floor but instead he was left on a bed, meaning first-aiders could not apply sufficient pressure on his chest. Murray insisted paramedics should continue trying to revive the singer as they rushed him to UCLA Medical Centre - although ambulance crews believed he was already dead.

Police investigating the singer's death have already ordered cardiologist Murray to remain in Los Angeles while they continue their inquiries. It emerged last night that Murray quit his Hollywood practice to become Jackson's personal doctor just 17 days ago. In a letter to patients he said he was leaving for a "once-in-a-lifetime opportunity". He was hired by the company behind the tragic star's punishing 50-night comeback tour at London's O2. Jackson had a fear of needles.

The doctor - who has a tangled financial and personal history - was the only other person in the room when he collapsed. Deputy Chief Charlie Beck said: "We think that he will assist us in coming to the truth of this case." Police are also said to want to talk to a second medical adviser,

Tohme R Tohme, who met the singer in Bahrain and is reported to have accompanied him to hospital on Thursday. The Los Angeles County coroner's office said there were no signs of foul play but determining the cause of death would require further tests that will take six to eight weeks. Police are probing claims that Jackson was given a daily cocktail of drugs and was hooked on the medication.

He even called his Demerol injections "health tonic". In 2007 Jackson settled a court action by Beverly Hills pharmacist Micky Fine for more than pounds 50,000 in unpaid prescription charges. Two years earlier he settled another pounds 30,000 bill when another LA pharmacy went to court. Dr Murray practises medicine in California, Nevada and Texas. His Nevada practice, Global Cardiovascular Associates, was slapped with more than pounds 140,000 in court judgements and he faces at least two other pending cases. He has luxury homes in Las Vegas and Los Angeles.

In a letter to his patients dated June 15, Dr Murray said: "Because of a oncein- a lifetime opportunity, I had to make a most difficult decision to cease practice of medicine indefinitely. "In my absence I will continue to manage the practice and be involved as much as possible but it will be from a distance. "Again I am deeply saddened to leave you at this point but please know my absence is not permanent." Concert promoter Randy Phillips revealed that Jackson insisted his AEG Live company hire Dr Murray to accompany the star to London for the O2 shows.

Rapport He said: "Michael said he had a rapport with him. He said, 'This whole business revolves around me. I'm a machine and we have to keep the machine well-oiled.' You don't argue with the King of Pop." The promoter said Jackson underwent "five-plus hours" of medical tests in February and passed with flying colours. But the Jackson family have requested a second independent post-mortem examination.

The first examination was completed on Friday and the body released to the star's family. Lawyer Brian Oxman, a family friend, said: "When Anna Nicole Smith passed away, I said we cannot have this kind of thing with Michael. "The result was I warned everyone, and lo and behold, here we are. "I don't know what caused his death - but I feared this day."

DOCTOR SLAMS HANGERS-ON

A DOCTOR who knew Michael Jackson well said that his prescription drugs habit was encouraged by the hangers-on who surrounded the tragic star. Deepak Chopra, right, also claimed Jackson had told his son Gotham: "I don't want to go out like Marlon Brando.

I want to go out like Elvis." Deepak said: "Michael was surrounded by enablers, including a shameful plethora of doctors in LA and elsewhere who supplied him with prescription drugs. "As many times as he would candidly confess that he had a problem, the conversation always ended with a deflection and denial." The doctor added: "The instant I heard of his death, I had a sinking feeling that prescription drugs would play a key part."
