The latest development to come out of the ongoing trial of Dr. Conrad Murray, who's being charged with the involuntary manslaughter of Michael Jackson, is making headlines after this Wednesday's (Oct. 12) court session.

Murray's lawyer announced that the doctor, who pleaded "not guilty" to charges he killed the King of Pop, is now abandoning his original defense. At the start of the trial, Murray's lawyers argued that the late singer accidentally killed himself by orally self-administering the fatal dose of the prescription drug Propofol -- a misstep that ended his life in June 2009.

As it turns out, an independent study by the defense found that swallowing Propofol would not produce fatal results, so taking the drug orally, as Murray claimed Jackson did, could not have killed him.

Lead lawyer Ed Chernoff said in his opening statements that the defense will now go on to claim that the lauded entertainer self-administered the fatal dose of the drug by injection, not by mouth.

The twist in the trial follows the recent revelation that Jackson's eldest children, Prince and Paris were in their famous father's bedroom at the time of his tragic passing.

If convicted, Murray faces four years in prison.
