In his book, Dear claims that he has the knife used in the murders, along with photos and other evidence that suggest the true killer was Jason Simpson, O.J.'s son with his first wife.
"When I tell you we have the weapon -- we found the weapon in Jason's storage facility that he failed to make payments on. We know he carried it -- his initials were carved in the leather sheath," Dear said.
"We have emails from his former roommates that were in college with him. We have our suspect's diaries. We have his forged time card, and we have the vehicle he was driving on the night of the murders," said Dear.
The private investigator also claims to have photos of Jason Simpson wearing the knit cap that was found at the murder scene.
But why? Why would Jason Simpson kill Brown and Goldman?
During O.J. Simpson's trial, prosecutors alleged that the defendant was obsessed with his ex-wife, that he was prone to jealous rages and that he would stalk her.
Dear contends that Jason Simpson has his own demons and suffers from "intermittent rage disorder."
"Our suspect at the time was 5'11" and 235 pounds," Dear said. "He was 24 years old, and he was on probation for assaulting his previous employer with a knife. In addition to that, he's had three attempted suicides and has been in a psychiatric unit.
