Schiavo Parents Consider Next Move

Autopsy Fails To Convince Them She Could Not Have Recovered

(CBS/AP)  The cause of death was dehydration from removal of the feeding tube, but the underlying reason for her brain damage was officially listed as "undetermined."

The autopsy included 274 external and internal body images and an exhaustive review of Schiavo's medical records, police reports and social services agency records.

Pinellas-Pasco Medical Examiner Dr. Jon Thogmartin said that the autopsy produced no conclusion on what triggered the temporary heart stoppage that caused her collapse and brain damage. He said there was no evidence of drug use, though he cautioned that Schiavo was not tested in 1990 for every conceivable substance that could have been in her blood.

He said there was no proof she suffered from an eating disorder such as bulimia, which can disrupt the body chemistry with lethal effect. The main piece of evidence cited for an eating disorder — the low levels of potassium in her blood in 1990 — could have been caused by the emergency treatment she received at the time, Thogmartin said.

While she had lost more than 100 pounds since high school, Schiavo never confessed to an eating disorder, she did not take diet pills and no one had witnessed her purging food, the medical examiner said.

He discounted the possibility that she had overdosed on caffeine from drinking large amounts of tea in an effort to keep her weight down.

In addition, the autopsy found no traces of morphine in her system at her death, although she had been given two doses in the days before she died. The Schindlers had contended that morphine might have been used to speed their daughter's death.
