Nick Reiner has been in a delirious state since the murders of his parents, appearing 'almost childlike' in jail, insiders have said. The 32-year-old is accused of brutally stabbing Rob and Michele Reiner to death at their home in Brentwood, Los Angeles, on December 14. The Hollywood director and his producer wife were found dead by their horrified daughter, Romy, and Nick was arrested later that day on suspicion of murder. TMZ executive producer Harvey Levin told Fox & Friends on Monday that the alleged killer is 'not competent to stand trial right now.' 'He is almost childlike in jail, we're told,' Levin said. 'He can't process the consequences of what he's done. He knows what he did. 'He just can't understand where he is right now, and I know that sounds crazy, but he is out of his head right now.' #news #crime #robreiner #nickreiner
