Testimony resumes in Michael Jackson trial

LOS ANGELES (AP) — An expert in the powerful anesthetic blamed for Michael Jackson's death has resumed testifying in the involuntary manslaughter trial of the singer's personal physician.



Dr. Steven Shafer is being cross-examined by Dr. Conrad Murray's lead defense attorney, Ed Chernoff. Shafer's testimony is expected to conclude Monday and the defense will begin its case.



Chernoff questioned Shafer about models detailing the effects of the anesthetic propofol that show that the risk of a patient's breathing stopping comes in the first few minutes after the drug is administered. Shafer agreed, but said it was hard to know exactly how propofol affected Jackson because he had other sedatives in his system and because he had been receiving propofol on a nightly basis for more than two months.



Murray has pleaded not guilty.
