The source also pointed to the Robert Blake case, which some experts believe was also botched. But the source added, "There is not a problem with the case. Time is on our side. We want to do this right." The L.A. County D.A.'s office and the LAPD are working as a unit to "anticipate defense strategies and prepare for them." The D.A.'s office is actively involved, requesting lots of info from the LAPD.
One of the issues: authorities have keyed in on Applied Pharmacy in Las Vegas -- they want to make sure there are no other pharmacies that sent the Propofol in question to Dr. Conrad Murray.
Another issue: authorities have gone back to their medical experts for more input, as "strategies have changed" in a case they call "very complicated."
As for when the investigation will wrap: now authorities are saying they'd like to end it "before the Christmas holidays".... but that could get pushed to January.
