On the one-year anniversary of Michael Jackson's death, his father, Joe Jackson, has filed a wrongful death lawsuit against Dr. Conrad Murray, E!Online is reporting. Jackson filed the lawsuit in federal court; Murray isn't a California resident, so Jackson couldn't file with the state. The lawsuit was filed at the federal court in downtown Los Angeles on Friday afternoon. Murray has also been charged with involuntary manslaughter in criminal court. That case will go to trial later this year.

In the lawsuit, Jackson makes several allegations against Murray. Perhaps the most significant accusation is Murray's withholding of important information about Michael's health that might have helped revive him when the paramedics first arrived on the scene.

Jackson also claims Murray withheld information from the emergency room doctors and only admitted to giving Michael three drugs--none of which were propofol, which he'd actually been taking for over four months. The omission "demonstrated a disregard for Michael Jackson's life," the lawsuit states.

The lawsuit also alleges negligent hiring, training and supervision of Murray. Specifically, the lawsuit states, "below the standard of care and ultimately resulted in Jackson's overmedication and death on June 25, 2009."
