The autopsy evidence and autopsy testimony about the two victims suggests that wounds were made to their bodies after their deaths, meaning that the victims were killed and then their bodies were positioned and additional wounds performed afterwards.

Nicole Brown Simpson did not aspirate any blood, nor did any blood enter her mouth or sinuses. The massive neck wound practically cut her head off, nicking her spinal column and bissecting her epiglottis. Cutting the epiglottis alone would have filled her mouth with blood. If she were breathing (that is, alive) when the neck wound was made she would also have aspirated blood (inhaled blood into her lungs).

Goldman's autopsy has similar problems. He was allegedly stabbed in the back, cutting the femoral artery. If that were the fatal wound his pleural cavity would have filled with blood until he collapsed and died. But something like a half-cup to a cup of blood was found in his chest cavity, meaning, again, that the wound was delivered post mortem. It also means, since Goldman was found slumped against a tree stump, that someone would have had to have lifted his dead body, stabbed him, and then placed him against the stump.

Each victim had also suffered a puncture of the right common carotid artery, at the location where morticians make incisions to drain blood from corpses as part of the preparation of a body for burial. If the other wounds were delivered after the death of the victims then these puncture wounds would explain how the blood got out of (was removed from?) their bodies beforehand.

While this does not absolutely rule out Simpson as killer, it certainly eliminates the prosecution's theory of the case. In order to have Simpson commit these crimes, he would have had to have delivered wounds that would not have necessarily stopped either victim from vocalizing calls for help, fighting, or fleeing the scene. Even if both victims immediately collapsed in shock, Simpson would still have to wait for five to ten minutes for the victims to fully bleed out, then perform the ghastly neck wound to Nicole Simpson and lift up Goldman, stab him in the back and position him against the tree stump. People who commit double homicides in the middle of L.A. don't generally stand around the crime scene for ten minutes in order to add additional but meaningless wounds and rearrange the bodies, especially if they've got a plane to catch.

As an aside, the Coroner's Investigator, her name was Ratcliffe, called the Browns the next morning and asked them when had been the last time they'd talked with their daughter. They said they'd spoken with her over the phone at 11 p.m. after they'd returned home from dinner. At 11 p.m. Simpson was putting his luggage into the limo for his ride to the airport.
