Defense attorneys for the doctor charged in Michael Jackson's death will get their chance Thursday to question the prosecution's final, and perhaps most damning witness.
For hours Wednesday, Dr. Steven Shafer told jurors hearing the involuntary manslaughter case how Dr. Conrad Murray committed so many mistakes in his treatment of the singer that some were previously inconceivable.
Murray's attorneys will have to somehow challenge Shafer's expertise and conclusions.
Shafer is a leading expert on the anesthetic propofol. Murray has acknowledged giving Jackson doses of the drug to try to help the singer sleep.
Murray has pleaded not guilty to involuntary manslaughter in connection with Jackson's sudden death in June 2009.
In all, Shafer said Murray committed 17 acts that could have led to serious injury or death.
