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 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 reports say there is evidence Dr. Murray may have administered the drug. Dr. Murray’s lawyer, Ed Chernoff, said he would neither confirm nor deny if Dr. Murray administered Propofol to Jackson.

Law enforcement sources tell say they concluded that the doctor administered the drug and 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 Boulvard.

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 said 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. 

TMZ broke the story on 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.

Meanwhile thousands of fans have thronged Michael Jackson’s birthplace of Gary, Indiana, to pay an emotional tribute to the King of Pop. 

Members of the singer’s family watched as local performers staged a medley of his greatest hits and youngsters mimicked his famous “moonwalk”.

Gary, an industrial city close to Chicago, was Jackson’s home for the first 11 years of his life. Although his formative years were unhappy ones, the mood of the festival was upbeat 

This is the origin of it all,” Jesse Jackson, the civil rights leader, told 6,000 devotees who joined the event at a local baseball ground. “This is where Michael learned to dance, where he learned to sing, where he learned to sacrifice.”

A seven-foot memorial to Gary’s most famous son was later unveiled by mayor Rudy Clay who hailed the singer for placing the city on the world map and told the crowd that he had moved on to a better place.

“He’s going to put on those golden slippers and he’s going to dance all over God’s heaven,” Mr Clay said.

Joe Jackson, the singer’s controversial father, arrived at the stadium two hours after the tribute began. Surrounded by security guards, he briefly greeted the crowd but otherwise kept a low profile.

The former crane operator has struggled to defend himself in the face of persistent allegations that he abused his son.

Mr Jackson, who on Friday said he suspected “foul play” in the singer’s death, is expected to be a key figure in custody hearings to determine who will act as guardian to the three Jackson grandchildren.

A judge has given Katherine Jackson, the singer’s mother, temporary guardianship but a hearing on whether or not she will continue in that role is expected next week.

Speculation has been mounting that Jackson’s ex-wife, Debbie Rowe, could seek custody of Prince Michael Jr and Paris, the two children she bore the star when they were married in the late 1990s.

Jackson’s third child, Prince Michael II, was born of a surrogate mother whose name has never been disclosed.
