Dr. Murray is currently being charged with involuntary manslaughter in Jackson's death.

According to Las Vegas pharmacist Tim Lopez, Murray purchased 125 vials of propofol at 20 milliliters and 130 vials of the powerful anesthetic at 100 milliliters.

While on the stand, Lopez said that he recalls the orders for propofol were placed between April 6 and June 10, 2009. Jackson died on June 25.

The preliminary hearing will determine whether the case will go to trial. The defense is making claims that Jackson killed himself with a lethal dose of propofol. The prosecution believes Dr. Murray is responsible for the singer's death.
