Michael Jackson RX

And one prominent L.A. dermatologist says "I.M. Injection" is commonly used as billing code for the narcotic Demerol.

In the documents, most of the procedures appear to be minor, such as acne treatments, lip treatments and Botox -- yet "I.M. Injection" appears over and over on Michael's bill, sometimes several times a day. The I.M. Injections correspond to the dates of the minor treatments.

In one particular case, Jackson went to Klein on April 23rd and received three "I.M. Injections" at $60 a pop.

Then, remarkably two days later -- on a Saturday -- Jackson went to Klein's office and got 4 more I.M. Injections to facilitate an injection of the smallest possible dose of Restylane -- a popular wrinkle-filler.

According to the docs, Arnie Klein -- Jackson's self-described good friend -- charged Jackson $7500 for the weekend visit.

Jackson's three month bill: $48,522.89.

TMZ has learned one of his bodyguards has been driving the BMW to the Santa Monica apartment of Murray baby mama Nicole Alvarez -- the same pad the doc used to have Michael Jackson's Propofol delivered from a Las Vegas pharmacy.

As we previously reported, Murray was living at the apartment, when he was giving Jackson nocturnal Propofol infusions at the singer's home.

There's a new drug problem in the U.S. -- Propofol.

We've called a bunch of hospitals and anesthesiologists who tell us ... since Michael Jackson's death a number of patients were worried sick about being put under with Propofol. The docs have had to walk their patients through the procedures they use to ensure safety.

We're told some patients are outright refusing to be put under with the drug that killed M.J.

The medical experts we've spoken with say Propofol is a great drug that is relatively safe when administered properly -- that was clearly not the case with Jackson.

Law enforcement sources tell TMZ the only person the LAPD is focusing on in Michael Jackson's homicide investigation is Dr. Conrad Murray.

TMZ has been reporting for weeks that other Jackson docs have been scrutinized by law enforcement and the L.A. County Coroner's office. Sources say, however, Dr. Murray is the only person in their crosshairs in the homicide investigation.

As for the other docs who prescribed to Michael Jackson, they are by no means in the clear. There is an active investigation on several fronts for fraudulent prescription practices as well as prescribing to an addict.

The document was updated to reflect the L.A. County Coroner's report which ruled Jackson's death a homicide.

The report also showed Michael's main cause of death was "acute Propofol intoxication" and a contributing factor was the presence of mulitple anxiety and insomnia medications in his system.

And now to link it all together ... a police affidavit shows Dr. Conrad Murray told cops he injected Michael with Propofol right before he died.

Did the other shoe drop? Have cops made their move? Nope. The nearby Roxbury Cafe has delicious breakfast burritos.

The doc shows on August 21, the DEA took "60 prescriptions, 29 patient print-outs, 3 copies of DEA Forms 222 (Order Forms), and copies of inventories of controlled substances."

Mickey Fine was used extensively by Dr. Arnold Klein and other doctors who treated Michael -- it's also where Jackson obtained prescriptions

Law enforcement sources tell TMZ the L.A. County Coroner and the LAPD are not buying Dr. Conrad Murray's story that he gave Michael Jackson a relatively low dosage of Propofol before he died.

Sources say the L.A. County Coroner has determined Michael Jackson died from a lethal level of Propofol. There were "traces" of other drugs in Jackson's system, but nothing that would have killed him.

According to the search warrant affidavit, during Dr. Murray's interview with LAPD detectives two days after Jackson died, he said he gave Jackson 25 milligrams of Propofol shortly before the singer stopped breathing. Dr. Murray also said he had been giving Jackson 50 milligrams of Propofol for the prior six weeks so Jackson could sleep, but he felt the singer may have been forming an addiction so he cut back.

Here's the reality. It takes approximately 400 milligrams of Propofol for someone of Jackson's body size to sleep 8 hours -- that's 16 times the amount Dr. Murray says he gave Jackson the day he died.

Our law enforcement sources simply do not believe that 25 milligrams would have in any way compromised Michael Jackson, especially since he had developed a tolerance to a much higher level.

Cherilyn Lee told us she never gave Michael Propofol or Diprivan. Lee said she gives people "nutritional cocktails" and Dr. Murray must have jumped to conclusions.

And this is interesting ... Lee also said she saw Michael back in April, and there were "no injection marks" on his body. Our law enforcement sources say Jackson was riddled with injection sites at the time of his death.

Lee said she did inject Michael with a "nutritional IV" of "basically vitamin C." She says, "Mr. Jackson had very small veins."

We've been telling you for weeks Propofol killed Michael Jackson and authorities had their sights set on Dr. Conrad Murray. The affidavit to the Houston search warrant makes it clear -- Dr. Murray fueled Jackson with multiple drugs before he stopped breathing and Propofol was the crowning blow.

So the questions -- did Dr. Murray come clean when he spoke with the LAPD or is it even worse than we thought? Why was he on the phone for 47 minutes after Jackson stopped breathing? Why did he wait so long to call 911? Why did he refuse to pronounce Jackson dead at UCLA? Why did Dr. Murray disappear for a day?

And the bigger question -- is Dr. Murray the patsy -- taking the heat for years of prescription abuse at the hands of various doctors?

What do you think?

Dr. Conrad Murray told cops he had been treating Jackson for 6 weeks for insomnia -- giving him 50 milligrams of Propofol every night through an IV.

Murray told cops he feared Jackson was getting addicted so he reduced the dosage to 25 mg.

The morning Jackson died, Dr. Murray gave Jackson valium at 1:30 AM. Murray said the valium didn't work so he gave the singer an IV injection of lorazepam -- an anti-anxiety drug. Murray told cops Jackson was still awake, so he then gave him midazolam -- a sedative.

Murray gave Jackson more drugs. He says at 10:40 AM, he administered 25 mg of Propofol. Dr. Murray told cops Jackson repeatedly demanded the drug.

As we first reported, cops found 8 bottles of Propofol in Jackson's house after he died, but they do not know where it was purchased.

Cops also found Valium, Tamsulosin, Lorazepam, Temazepam, Clonazepam, Trazodone and Tizanidine, along with the Propofol.

The various drugs were prescribed by Dr. Murray, Dr. Arnold Klein and Dr. Allan Metzger.

Dr. Murray reportedly told cops 10 minutes after administering Propofol ... he "left Jackson's side to go to the restroom and relieve himself. Murray stated he was out of the room for about 2 minutes maximum. Upon his return, Murray noticed that Jackson was no longer breathing."

Dr. Murray says he began CPR and at some point ran downstairs and asked the chef to send up Prince Jackson, the eldest son, then Murray continued performing CPR.

Dr. Murray says he noticed that Jackson wasn't breathing at around 11 AM. He was then on the cell phone for 47 minutes with 3 separate calls, from 11:18 to 12:05. The 911 call came in at 12:21 PM .... a much longer delay than originally reported.

Dr. Murray told cops other docs had administered Propofol to Jackson, including Las Vegas Dr. David Adams. Dr. Murray said he was at a cosmetologist's office where Dr. Adams gave Jackson Propofol.

Interestingly, according to the warrant, Dr. Murray refused to sign the death certificate at the UCLA Medical Center.

UPDATE: If Dr. Murray is charged with a crime, there's a statement in the affidavit that could be evidence of a consciousness of guilt. The document also states both "UCLA doctors and L.A. Fire Dept. paramedics stated that Dr. Murray had only disclosed that he had given the medication Lorazepam [Ativan] to Jackson prior to his medical emergency." Dr. Murray did not disclose that he had given Jackson Propofol.

Dr. Conrad Murray's lawyer, Ed Chernoff, just released the following statement regarding the affidavit we published today, in which authorities recount Dr. Murray's blow-by-blow account of the day Michael Jackson died:

"Much of what was in the search warrant affidavit is factual. However, unfortunately, much is police theory. Most egregiously, the timeline reported by law enforcement was not obtained through interviews with Dr. Murray, as was implied by the affidavit. Dr. Murray simply never told investigators that he found Michael Jackson at 11:00 am not breathing.

Law enforcement sources tell us they are searching for evidence of "improper dispensing of controlled substances," in connection with the death of Michael Jackson.

The pharmacy was used extensively by Dr. Arnold Klein and other doctors who treated Michael Jackson. Jackson obtained prescriptions for Demerol and many other drugs at Mickey Fine.

Mickey Fine sued Michael Jackson in 2007 for non-payment of a bill of more than $100,000. The case settled.

UPDATE: 4:51 PM PT Law enforcement sources tell TMZ the DEA found irregularities in Mickey Fine's drug dispensing practices when it came to Michael Jackson. Agents are searching records at the pharmacy for the various aliases Jackson used.

Dr. Conrad Murray may be on the hotseat with the LAPD over Michael Jackson's death, but that's not going to cramp his style when it comes to proving to the world he's a beloved MD.

In addition to his "thank you" video, Dr. Murray posted contact info for 14 of his patients who would give testimonials. They wouldn't talk Propofol, but were more than eager to give props to the good doc.

Here are a few highlights:

Rev. Floyd Williams: "If Murray wasn't black, none of this would be happening. It's the media hype to show that black folks are still the minority"

Eliza Robertson: "If Katherine [Jackson] is that concerned she should have stopped all of the painkillers [Michael] was taking before. I would have tried to get him on a better road."

"[Dr. Murray] would leave Las Vegas and come take care of me in my home [in Houston], and pay me visits, and give me checkups. I don't believe that Murray would have given or prescribed MJ anything he didn't ask for."

Ben Mask: "When Dr. Murray moved his office into my neighborhood there wasn't a lot of money out here just a lot of old people living off checks. When he came out here he was behind on his bills and he needed the money. If I was in his shoes I would have taken the money too. It was an offer he couldn't refuse. It could be a set up ... You just never know, things are so crooked."

Robert "Bobby" Day: "He was the type of doctor that people would want to hug on their way out. He never rushed people and he was wonderful with following up. Everyone adored him."

Joseph Middleton tells TMZ the morning of June 25, one of his nieces, LaQuisha Middleton, had just arrived at Dr. Murray's medical practice where she worked when she received a call to go to the storage facility. Joseph does not know who called LaQuisha, but based on his conversations with her, he says the call came either from Dr. Murray or someone who works for Dr. Murray. He also says she went with another woman who was not LaQuanda Price, LaQuisha's sister.

The manager of the storage facility tells us two women, whom she believed at the time to be Laquisha and LaQuanda, arrived at 9:22 AM (Houston time) and picked up 3-5 boxes, as well as other items.

Joseph says LaQuanda told him LaQuisha picked up a chair and boxes, although when we interviewed LaQuanda in Houston, she only remembers a box -- she says a box containing dirty needles that LaQuisha inexplicably brought back to the office. In the same interview, LaQuisha only admitted picking up a chair.

Joseph told us LaQuisha got the call at around 9 AM Houston time. That is 7 AM Los Angeles time, more than 5 hours before Dr. Murray called 911.

As we first reported, it took multiple bottles of Propofol to keep Michael Jackson asleep through a single night. Law enforcement sources tell us they believe -- though cannot prove yet -- that Propofol bottles may have been stored at one or more locations under the control of Dr. Murray and FedExed to L.A.

Law enforcement has a suspicion Dr. Murray walked out of the room for a period of time after administering the Propofol, possibly fell asleep, and when he returned Jackson had stopped breathing. Cops think Dr. Murray then may have spent hours "cleaning up" the situation before calling 911.
