Local office searched in Jackson case

The local office of another doctor is searched in the case of Michael Jackson's death.Armed with a subpoena, the assistant chief coroner searched Dr. Lawrence Koplin's office Wednesday. Koplin's colleague, Dr. Arnold Klein reportedly performed a minor procedure using Koplin's nurse anesthetist.

The warrant follows two searches Tuesday at the home and office of Dr. Conrad Murray, Michael Jackson's attending physician.

His spokesman confirms that the detectives were looking for prescriptions, files, billing information, anything tied to a long list of fake names used by Jackson.

Yet it is the outcome of toxicology tests that will be crucial in determining Dr. Murray's culpability. He reportedly administered Propofol to Jackson the day before he died. Now there's fresh insight into several factors that may cloud the toxicology report.

"It could be incredibly complicated," said Dr. Jason Hymes.

Dr. Hymes is a board certified anesthesiologist, and an addiction specialist. What happens when a patient gets an IV drip of Propofol over hours, instead of minutes? What happens if Jackson took it night after night? He says there comes a saturation point.

"And if it rises it could impact the respiratory center to a greater and greater degree," said Hymes.

Add to that Jackson's intense rehearsals.

"The oxygen level drops off a little bit more than it usually does. And on that particular instance it was enough to tip the balance in any given person to where a serious event occurred," said Dr. Hymes.

Jackson died when his heart stopped, likely says Hymes after a slow process of many changes.

"If you do any one thing enough the likelihood of something happening to you goes up," said Dr. Hymes.

Meanwhile the toxicology results are on hold. They will be released when Chief William Bratton returns to Los Angeles next week.
