Testimony came to a halt Monday in the trial of Dr. Conrad Murray after defense witness Dr. Paul White claimed that Michael Jackson had his own stash of propofol, in addition to what Murray had purchased for the singer.

"Well, Conrad Murray certainly purchased propofol, but I understand Mr. Jackson had his own supply as well," White said on the stand. After the prosecution objected, accusing White of "throwing out these rehearsed lines," the remarks were stricken from the record and the jury was excused. The Telegraph reports that White was fined $1,000 by the judge for discussing inadmissible evidence.

Earlier, White had attempted to bolster the defense theory that Jackson gave himself additional propofol while Murray was out of the room. When asked point-blank if he believes the evidence shows that Michael Jackson died from a self-administered shot of propofol, Dr. White said, "In my opinion, yes."

White also testified that, in his experience, after administering a small dose of propofol to a patient and observing no adverse reaction for a minimum of 15 minutes, he would feel comfortable leaving the patient's side. That bit of testimony could be important for the defense, given that Dr. Murray left Jackson to make phone calls on the morning he died.

CNN reports that Dr. White was the final defense witness in the trial against Murray, who is charged with involuntary manslaughter. When asked if he wanted to take the stand, Murray told the court, "My decision is that I will not testify in this matter." Both sides rested their cases on Tuesday, and the judge scheduled closing arguments to begin on Thursday.
