Shortly after the latest revelations accusing Michael Jackson's doctor, Conrad Murray, of negligent behavior that led to his sudden death, the Jackson family released a statement saying they "look forward to justice," Us Weekly reports. Still, several questions remain that will determine the extent of the charges brought against Murray—and Jackson's final hours are still clouded by mystery. A police affidavit alleges that Murray did not phone paramedics for 82 minutes after noticing that Jackson had stopped breathing. It also accuses Murray of failing to inform medical staff that he had administered the powerful anesthetic Propofol to the singer. Investigators are determining whether they will accuse of Murray of bearing the responsibility of Jacko's death, or if "grossly negligent treatment of several doctors" is to blame.
