Washington, July 1 (ANI): Michael Jackson’s friend Deepak Chopra has joined other critics in casting a shadow of doubt over the actions of the late singer’s doctor in the star’s finals moments.

Dr. Conrad Murray was said to have spent 30 minutes performing CPR on the unconscious King of Pop before calling 911.

He evoked serious criticism for performing CPR on Jackson’s bed, and not on the floor, where it would have been more effective.

Experts further slammed Murray, questioning why he waited half an hour to call for the emergency services.

Murray, who was quizzed for three hours by the Los Angeles Police Department on June 27, was also suspected of injecting Jackson with the potent painkiller Demerol before the star collapsed in his home.

Jackson died aged 50 on June 25 from an apparent cardiac arrest purportedly triggered by an overdose of prescription pills.

And now revered Indian-American medic Chopra has questioned why Murray did not use withdrawal drug Narcan when he had realised the icon was unconscious from an apparent drug overdose.

“Any emergency room or any doctor who sees a doctor with an overdose, the first thing they do is give Narcan… Within minutes you see a response,” Contactmusic quoted him as saying.

However, Murray’s lawyer, Edward Chernoff, said that contrary to reports, the doctor did not give Jackson the powerful painkillers in the hours leading up to his death.

He said: “I believe when the toxicology (results) come back, you’re not going to find narcotics.” (ANI)
