Conrad Murray Trial

Turns out this isn't the first time Dr. Arnold Klein has resisted turning over Michael Jackson's medical records to authorities -- according to a Santa Barbara County deputy sheriff.

As we first reported, the L.A. County Coroner has requested medical records from Dr. Klein and authorities tell us he has not fully cooperated. But the same thing happened during the first child molestation investigation targeting Jackson.

We've obtained Santa Barbara Sheriff's Department documents from the 2005 Jackson prosecution. A deputy sheriff wrote an affidavit recounting that on November 19, 1993, she served a search warrant at Dr. Klein's Beverly Hills office, looking for Michael Jackson's medical records.

The deputy's affidavit says she spoke with Dr. Klein when the warrant was served. Her affidavit says, "Dr. Klein said that prior to the service of the search warrant on November 19,1993, he removed Jackson's medical files from his office at Mr. Andelson's (his lawyer's) direction and kept the files in his home and car."

As for why authorities searched Klein's office -- Jackson's accuser in 1993 told authorities the singer's genital area had distinct color patterns because of vitiligo. Authorities were told Jackson obtained skin-lightening prescriptions from Klein and other docs to treat the disease and may have changed the coloring of the area so the accuser's description would not match.

Law enforcement sources tell TMZ the central target in both the coroner and LAPD investigations into Michael Jackson's death is Dr. Conrad Murray, who was at Jackson's house when the singer went into full cardiac arrest.

Sources say the doctor is not cooperating with authorities, but they have still found evidence linking him to the drug that may have killed Jackson. As we first reported, as a result of Dr. Murray's second interview with police two weeks ago today, the LAPD obtained a warrant to conduct a second search of Jackson's home -- and that's when they found Propofol, a powerful anesthesia that should never be used outside a hospital. There is evidence Propofol was administered to Jackson shortly before his heart stopped beating.

And we're told there is evidence Dr. Murray may have administered the drug. Dr. Murray's lawyer, Ed Chernoff, told TMZ he would neither confirm nor deny if Dr. Murray administered Propofol to Jackson. Law enforcement sources tell us if they conclude the doctor administered the drug it may well lead to manslaughter charges.

Investigators are also suspicious of the delay in calling 911 -- the Dr. says he waited 20 - 30 minutes because he didn't know Jackson's address that would lead paramedics to the house. Jackson lived on one of the most famous streets in the world -- one house above Sunset Blvd.

As the investigation into Jackson's death heats up, there's also an investigation into his life with drugs and the doctor's who fueled it. Sources tell us law enforcement is seriously investigating the prescription practices of several doctors who gave Jackson access to medications. Investigators are particularly interested in doctors who used aliases to write scripts for Jackson. One of the central figures in the investigation -- Dr. Arnold Klein.

We broke the story yesterday how members of Jackson's staff complained that Klein was using the names of employees and others to help Jackson score drugs. One of the names allegedly used -- Frank Tyson, a former Jackson employee. Several powerful meds in Tyson's name were prescribed by Dr. Klein and found at the Neverland Ranch during the 2003 search.

Klein says it was only "on occasion" to sedate him, and when asked about the drug Diprivan -- the brand name for the drug Propofol, which was found in Jackson's house when he died -- Klein said he was aware Michael was using it but warned him of its dangers.

As for fathering Michael's kids, Klein admits to donating sperm once -- to a sperm bank -- not specifically to Jackson. Klein hedged on whether he was the father of Jackson's kids but at one point said he was not.

Klein also strongly intimated he felt Debbie Rowe should get the kids -- because he felt Katherine was too old and Joe was out of it. Interestingly, Klein didn't go to the memorial and as we reported, the Jackson family gave LAPD a list of doctors they were suspicious of -- and Klein was on the list.

Klein says he actually warned Michael that certain drugs -- like the opiate Dilaudid -- were "poison," calling doctors who did supply Michael with prescription drugs "criminals."

As for those pesky paternity rumors, his ominous answer: "To the best of my knowledge, I'm not the father."

We're inside the courtroom as the lawyer for the co-executors of Michael Jackson's will, John Branca and John McClain, go before a judge seeking to be named administrator of Jackson's estate.

1:08 PM ET -- Hearing is over.

1:02 PM ET -- The judge just said that decisions involving marshaling the assets, attorney's fees, and settling claims and actions all require court approval -- as well as any modifications to existing court agreements and decisions

1:00 PM ET -- The judge just made it clear -- Katherine is NOT a co-administrator and she is not required to be involved in every decision. But, he pointed out, her attorney does have the ability to object.

12:54 PM ET -- The executors are also interested in operating his businesses (employees, investments, etc.) but any new business ventures would be subject to court approval.

12:49 PM ET -- The lawyer for the executors is balking about giving Katherine approval power. The judge has said he wants the executors to keep Katherine in the loop about decisions being brought before the court.

The lawyer for the doctor who was at Michael Jackson's home the day he died tells TMZ he did not give Jackson OxyContin or Demerol that day, but he wouldn't say the same about the powerful anesthesia found at the singer's home.

Dr. Conrad Murray was interviewed by LAPD detectives a week ago Saturday. Law enforcement sources tell us the information Dr. Murray gave police regarding drugs at Jackson's home was enough for cops to secure a search warrant from a judge. A search warrant can only be issued if there is probable cause to believe a crime has been committed.

Law enforcement sources say when police searched the home, they found the powerful anesthesia Propofol. The drug was specifically labeled Propofol and there was no indication it had been prescribed to anyone.

Edward Chernoff reiterated to us his client did not administer Demerol or OxyContin to Jackson the day he died. But Chernoff would not take the same stand on Propofol. Chernoff told us, "I have no statement on whether the Dr. prescribed or administered Propofol."

Chernoff added, "We're confident whatever the doctor prescribed did not kill Michael Jackson."

As we reported last week, cops obtained a search warrant the day after Jackson died. A second warrant was issued two days after Dr. Murray's interview -- that's the one that led cops to the Propofol. The second warrant may have been necessary if the first warrant only covered prescription medications.

The LAPD and the DEA are on the hunt to determine how the Propofol ended up in Jackson's home. The drug should never be administered outside a hospital.

UPDATE: A spokesman for attorney Ed Chernoff just called to say when Chernoff spoke with TMZ last night "He was not conscious. He had just woken up and he can't speak for anything that was in the home."

In fact, it was just after midnight Houston time when we spoke with him. We were on the phone with Chernoff for nearly 20 minutes. He repeated multiple times that he had no comment regarding the Propofol. Aside from the comments we quoted above, Chernoff said, "I have no comment on whether the doctor administered Propofol." He also said, "I can't deny or admit what the doctor might have prescribed." He also said "I can't say if the doctor gave him Propofol."

Chernoff went on to talk about the LAPD investigation, sounding very alert and choosing his words carefully: "When all the results come in, the truth will come out and the correct result will be obtained." He also asked questions about what we knew regarding which drug may have killed Michael Jackson.

UPDATE: The judge in the case has ruled Katherine will remain as temporary administrator for the rest of the week. The judge said it wasn't urgent to change things up immediately -- that the matter will be heard Monday.

There's a hearing underway over Michael Jackson's will.

Here's the problem. On Monday, Katherine's lawyers got an order from the judge making Katherine the temporary administrator of her son's estate, based on her belief that no will existed.

Now that a will has been filed, the named executors want to make sure they have control over the assets and are asking the judge to nullify Katherine's power to move assets around -- even temporarily.

In a statement that was set to be released in a couple of hours -- that somehow leaked -- AEG promises "the refunds will be processed by each of the authorised ticket agencies (e.g. Ticketmaster, Viagogo, See or Ticketline)."

And the statement says fans "will have the option to be sent the actual tickets" for the show. Translation -- one hell of an expensive keepsake.

Dr. Conrad Murray sent the note on his letterhead from his medical practice in Las Vegas. He says, "I am deeply saddened to leave you at this point, but please know my absence is not permanent." He continues, "In my absence, I will continue to manage the practice, and be involved as much as possible but from a distance."

The letter says "My absence is not permanent."

We're told AEG -- the company that was putting on the London concerts -- put Dr. Murray on the payroll.
