(CBS/WKMG/AP) ORLANDO, Fla. - The defense is expected to call its first witness today in the murder trial of Florida mother Casey Anthony, who is accused of killing her 2-year-old daughter Caylee in 2008.
The prosecution has presented all of its evidence and Thursday jurors will look towards Anthony's attorneys to begin delivering on the argument made in opening statements, where they said that Caylee accidentally drowned in the family pool.
One of the defense's star witnesses will be Dr. Werner Spitz, who disagrees with prosecutors that claim Anthony suffocated Caylee with duct tape, reports CBS affiliate WKMG.
Spitz, a former chief medical examiner in Michigan, performed a second autopsy on Caylee's body. He says he picks and chooses the cases he's involved in, and the Anthony murder trial was one he was particularly interested in, reports the station.
He questions the failure of Dr. Jan C. Garavaglia, chief medical examiner for the District Nine Medical Examiner's Office in Florida, to open the child's skull during the original autopsy, a procedure that he believes could have solved the case, the station reports.
Spitz said Caylee's bones showed no sign of trauma and he has not ruled out drowning as a cause of death.
He will share his own autopsy finding during his testimony at the trial on Friday.
Anthony, 25, has pleaded not guilty and could face the death penalty if convicted.
