A Los Angeles prosecutor said lawyers for Michael Jackson's doctor will claim that the singer killed himself.
Los Angeles County Deputy District Attorney David Walgren revealed the possible defense strategy during a hearing on Wednesday during an argument over who should test residue from two syringes found in Jackson's bedroom.
Dr. Conrad Murray is charged wth involuntary manslaughter in connection with Jackson's June 2009 death.
Defense attorney J. Michael Flanagan said a huge amount of the anesthetic Propofol was found in Jackson's body, but Conrad said he gave him only 25 milligrams of the drug.
Walgren suggested the defense will claim Jackson killed himself by injecting more of the drug into himself.
Preliminary hearings in the case begin January 4th.
