Conrad MurrayNew information obtained by TMZ suggests that lawyers for Dr. Conrad Murray, who faces a manslaughter charge in Michael Jackson's death, will argue that Jackson himself administered the fatal dose of Propofol. Sources tell the site that Murray admits giving Jackson a 25 mg dose of Propofol, enough to keep a patient asleep for only 10 minutes. The defense will reportedly claim that Ativan and Versed already present in MJ's system created a "synergistic effect" that put the singer to sleep for much longer.

It's when Murray left the room briefly, his lawyers will argue, that Jackson awoke and injected the remainder of a 20 ml bottle of Propofol into his IV. This injection caused a massive overdose that stopped his heart.
