Dr. Jan Garavaglia, Chief Medical Examiner for Orange/Osceola Counties, determined that two-year-old Caylee Anthony's death was a homicide, but couldn't conclude the exact cause of death.
Garavaglia said it's difficult to determine the cause when the body is that decomposed. Although there wasn't noticeable trauma to Caylee's bones, it is impossible to determine any trauma in her tissue. But traces of chloroform, which could kill a child, were found in air samples from Anthony's car.
The doctor noted the factors that led her to believe Caylee's death was a homicide:
1) Caylee wasn't reported missing
2) The fact that Caylee's body was hidden
3) Duct tape on Caylee's face
Casey Anthony is charged with first-degree murder of her daughter, and could face the death penalty if convicted.
