Dr. Conrad Murray, the doctor who was at Michael Jackson's home the day he died did not give Jackson OxyContin or Demerol that day, according to his attorney.
His lawyer, Edward Chernoff, wouldn't make the same statement about the powerful anesthesia, Propofol, that was found at the late star's home, however.
Law enforcement sources say the information Dr. Murray gave police regarding drugs at Jackson's home was enough for cops to secure a warrant from a judge.
This alone is a significant development, as a search warrant can only be issued if there is probable cause to believe a crime has been committed.
The facts: When police searched the home, they found Propofol. It was specifically labeled Propofol. There was no indication it had been prescribed to anyone.
Chernoff reiterated earlier claims that his client did not give Demerol or OxyContin to Jackson the day he died. But he would not take the same stand on Propofol.
Chernoff told TMZ when asked for comment on the subject, "I have no statement on whether the doctor prescribed or administered Propofol," adding, "We're confident whatever the doctor prescribed did not kill Michael Jackson."
Police obtained a search warrant the day after Michael Jackson died. Another warrant was issued two days after Dr. Conrad Murray's interview with LAPD investigators, and that's the one that led cops to the Propofol discovery.
A second warrant may have been needed if the first covered prescription medications only. DEA and LAPD officials are trying to determine how the Propofol - a drug that should never be administered outside a hospital - ended up in MJ's home.
Jackson's medical records and billing info may be the key to unraveling the mystery of who prescribed what to him and when - and holding the doctors responsible.
