Jackson had pulse when found, lawyer for doctor says

Murray was interviewed by investigators for three hours Saturday. His spokeswoman called Murray "a witness to this tragedy," not a suspect in the death, and police described the doctor as cooperative.

The attorney said Murray will wait to speak publicly until after the police and forensics investigation is complete.

"One of his best friends just died, essentially in his arms — yeah he's looking forward to telling his story," Chernoff said.

Chernoff also said the promoter of Jackson's 50-show London concerts, AEG Live, owes the cardiologist $300,000.

"His contract with the promoters states he would receive an amount of money each month to be his (Jackson's) personal physician and they have failed to honor that contract," Chernoff said. "They are two months behind."

Randy Phillips, president and CEO of AEG Live, acknowledged the contract called for Murray to be paid $150,000 a month, but said the contract required Jackson's signature.

"Michael never signed the contract," Phillips said.

He also said the doctor's claim for payment may be against Jackson's estate, not AEG which was merely advancing the money to Jackson.

A private pathologist hired by the Jackson family completed a second, private autopsy Saturday, the Los Angeles Times reported, citing unnamed people familiar with the case.

A second autopsy can allow the family to get some information about a death almost immediately, including signs of heart, brain or lung disease or fresh needle punctures, said Dr. Michael Baden, a medical examiner not involved in the Jackson case.

"Usually if it looks normal with the naked eye, it looks normal under the microscope," said Baden, who recently performed a second autopsy on actor David Carradine.

Los Angeles County coroner's officials said their autopsy found no indication of trauma or foul play. But because of additional tests, an official cause of death could take weeks to determine.

There was no word from the Jackson family on funeral plans. Many of Jackson's relatives have gathered at the family's Encino compound, caring there for Jackson's three children.

Al Sharpton, who arrived in Los Angeles on Sunday afternoon, said he was heading to the Jackson compound and would talk with the family about how to memorialize the late pop star. Sharpton said they want to hold memorials in key cities around the globe and also planned a memorial service Tuesday at the Apollo Theater in New York.

It also wasn't clear what would become of Jackson's Neverland Ranch. Investor Thomas Barrack previously set up the joint venture with Michael Jackson after the singer nearly lost the ranch to foreclosure.

Barrack feels close to family members and wants to hear their thoughts on how best to honor Jackson's memory, said Owen Blicksilver, a spokesman for Colony Capital LLC, the Los Angeles-based firm where Barrack is chairman and CEO. The investor joined Jackson's brothers Jackie, Jermaine and Tito for lunch Saturday at the sprawling Santa Barbara County property.

A White House adviser said on NBC's "Meet the Press" that President Barack Obama had written to the Jackson family to express his condolences.
