-I have here the detailed autopsy report
of Nicole Brown Simpson.
Nicole had multiple stab wounds to her body,
and Ron had even more stabbing injuries
and a very unusual wound to his left thigh,
and it's these injuries that are the starting point
in my forensic investigation into these killings.
The wounds are focused in a highly concentrated area.
These are not the pattern of wounds I would expect to see
from someone who had simply been disturbed.
In my opinion, this is a premeditated murder.
Much of the evidence being called
was believed to point directly to O.J. Simpson's guilt.
But at the end of his criminal trial,
he was found not guilty.
So, nearly 20 years on,
how can the forensic interpretation
of these autopsy reports
help us to identify anything more about the killer?
There was evidence at the crime scene
that another person had been present.
The individual whose tissues were under Nicole's fingernails
was never identified.
There were the unexplained footprints.
And there were drips of blood that couldn't be identified
as being either Nicole's or Ron's.
Could this person be Jason Simpson?
