Dr. Conrad Murray wants a judge to toss out the wrongful death lawsuit filed against him by Michael Jackson's father, Joe. Not only does Murray claim the elder Jackson has no legal right to file against him, but more explosively the doctor is claiming the King of Pop is responsible for his own death. In documents filed in court last Friday, Murray's lawyers claim that Jackson had been secretly administering his own Propofol without the doctor's knowledge and ended up killing himself. Jackson, they allege, "clandestinely self-administered or self-injested such medications" and "is comparatively responsible for his own death," assuming that the drugs killed him. Jackson's father filed his wrongful death lawsuit against the doc last year, which claims that Murray withheld the singer's medical history from emergency room attendants after Michael was taken to the hospital and initially only admitted to administering three drugs to the "Billie Jean" singer, none of them Propofol. Joe's lawsuit also states the omission "demonstrated a disregard for Michael Jackson's life" and accuses Murray of giving conflicting statements to police about Michael's drug use. Conrad's filing claims Michael Jackson had been visiting other doctors who doled out meds to the singer, and that the singer did not provide Murray with his full medical history or an accurate accounting of the meds he was on.
