Michael Jackson trial sleep expert: 'Treatment a recipe for disaster'

A sleep expert has described Conrad Murray's prescription of drugs for Michael Jackson as a "recipe for disaster".

Nader Kamanger testified in the case on Thursday, saying that Murray's treatment was "unethical, disturbing and beyond comprehension".

"To summarise, Mr Jackson was receiving very inappropriate therapy in a home setting, receiving very potent therapies without monitoring," Kamanger told the court.

Kamanger went on to condemn Murray's failure to record his treatment of Jackson.

"There were no records whatsoever," he said. "It's very easy to forget details. We do not rely on memory."

He continued: "It is an egregious violation of the standard of care when you are using sedatives like propofol and you are not writing it down."

Finally, Kamanger suggested that Murray waited too long to call 911 after he found Jackson not breathing.

"The most important thing he should have done is call for help," Kamanger said.

On Wednesday, Murray's defence team dropped their original claim that Jackson swallowed the anaesthetic propofol himself on the day he died.

Meanwhile, on Tuesday, Dr Christopher Rogers Murray's defence team dropped their original claim that Jackson swallowed the anaesthetic propofol himself prior to his death.

The trial is scheduled to continue for another four weeks, and Murray could face up to four years in prison if found guilty.
