The 40-year-old actor and his friend lost their lives in a fiery car crash on November 30 after their vehicle crashed into a tree and burst into flames, reported TMZ online.
The coroner needs the actor's dental records to identify the body.
"The bodies of Paul and his friend/business partner Roger Rodas are currently unidentifiable and their autopsies will be delayed until later this week," said a representative for the LA County Coroner.
