MICHAEL JACKSON TRIAL DAY 12: The prosecution continued to call medical experts yesterday (Thursday) in an effort to show that Conrad Murray's incompetence and misdeeds directly caused the death of Michael Jackson two years ago.

Dr. Nader Kamangar, a specialist in sleep medicine, said that Murray's prescribing of three different sedatives was "a recipe for disaster" and that the doctor had not given any thought to Jacko's treatment.

Murray's defense attorneys tried to shift some of the blame to Jackson's plastic surgeon Arnold Klein, who had given the singer large numbers of prescriptions to the painkiller Demerol. But while Dr. Kamangar granted that Demerol could have caused Jackson to suffer from insomnia, he ruled it out as a contributing factor in his death.
