Michael Jackson Dies

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.

On his blog, Gotham Chopra -- friend to MJ and the reporters -- says Jackson called him three weeks ago asking how he could help. Jackson thought Jong Il would let them go if he talked to him ... provided the North Korean leader was a fan.

One reason why Michael thought Jong Il could be a devotee: "You know, he wears jackets like mine."

Gotham told Jackson he'd look into it -- but Michael died before the plan could get off the ground.

We also have some cute shots of MJ hangin' out with the kids.

In a news conference moments ago on Capitol Hill, Pelosi said that while Jackson was "a great performer," a resolution "will open up two contrary views that are not necessary at this time to be expressed."

Somewhere Rep. Pete King is doing a righteous fist pump.

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.

Dr. Conrad Murray -- the doctor who was at Michael Jackson's home the day he died -- was once under investigation for an alleged botched surgery.

In 2007, Dr. Murray drained fluid from the heart of a 67-year-old Las Vegas patient. The patient died after surgery. According to the coroner's investigation report, his wife was told by one of the docs her husband's heart was punctured during the procedure -- so she complained to the coroner's office.

The investigation report confirms that, during Dr. Murray's surgery, the patient suffered a puncture to the right ventricle of his heart, which was eventually listed as one of four causes of death on the autopsy report.

We spoke to the family, who told us they wanted to file a malpractice suit but it was too expensive -- in part because pursuing that kind of legal action requires testimony from another medical expert, and that costs a lot of money.

Law enforcement sources tell TMZ Michael Jackson's family has given the LAPD a list of doctors they believe may have misprescribed drugs to Michael Jackson -- and we've learned Dr. Arnold Klein is on that list.

Dr. Klein came out swinging today on TV, denying he ever prescribed powerful painkillers to Jackson. But the family has its suspicions and passed its concerns along to detectives.

Congresswoman Sheila Jackson Lee, who spoke at yesterday's memorial, is pushing for a measure which would recognize Jackson as a "global humanitarian and a noted leader."

Jim McDermott (D-WA), John Lewis (D-GA) and Shelley Berkley (D-NV) are in -- with Lewis making a point to call King's comments "out of line" and "unnecessary."

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."

Though she was not at the memorial service today, Diana Ross, who Micheal requested look after his kids in his will if his mother was unable to, released the following statement:

"Yes, he did violate young boys. He did put them in terribly inappropriate positions. And that's a terrible signal to be sending out to society," the NY Congressman told CBS 2 today, among other gems.

King swears he won't speak out against MJ tomorrow -- out of respect for his memorial.

We got a pair of tickets for tomorrow's memorial... btw, the ticket is useless without the wristband.

Taylor just wrote on her Twitter: "I've been asked to speak at the Staples Center. I cannot be part of the public whoopla. And I cannot guarantee that I would be coherent to say a word. I just don't believe that Michael would want me to share my grief with millions of others. How I feel is between us. Not a public event. I said I wouldn't go to the Staples Center and I certainly don't want to become a part of it. I love him too much."

And, for the record, she also writes she's "not on suicide watch."

The Jackson family just announced everyone who will participate in tomorrow's memorial -- and here's the list:

Ron Boyd (family friend), Kobe Bryant, Mariah Carey, Andrae Crouch Choir, Berry Gordy, Jennifer Hudson, Shaheen Jafargholi (finalist on Britain's Got Talent), Magic Johnson, Martin Luther King III, Bernice A. King, John Mayer, Lionel Richie, Smokey Robinson, Rev. Al Sharpton, Brooke Shields, Pastor Lucious Smith (family friend), Usher and Stevie Wonder.

The deadline to pick up Michael Jackson memorial tickets is causing a frenzy, because some of the ticket holders -- especially those who live out of state -- can't make it to the ticket counter by the 6PM deadline.

Right now, anyone who was selected to attend must present the voucher for their tickets by 6PM at Dodger Stadium.

An AEG spokesman tells us they've been receiving complaints and are now considering pushing the deadline.

Stay tuned...
