Rob Reiner‘s son Nick Reiner will not appear in court today, December 16, because he is not medically cleared.

Nick is charged with murdering his parents, Rob, 78, and Michele, 68, at their Brentwood, California mansion on Sunday, December 14.

The troubled 32-year-old was arrested hours after his parents were found with their throats slashed on Sunday.

His high-profile lawyer Alan Jackson told reporters Nick is not medically cleared to be transported from jail to the courthouse.

That could mean he is on suicide watch or he probably refused to appear in court via Zoom from the jail.

Los Angeles County Sheriff’s online records previously indicated Nick was being held on $4 million bail. But his bail was revoked. It’s not clear why.

Nick struggled with drug abuse and homelessness over the years. He cycled in and out of drug rehab for most of his adult life.

Nick is Rob and Michelle’s middle child. He has 2 siblings, Jake and Rony. Rob also adopted Tracy, the daughter of his first wife Penny Marshall.

Rob Reiner is best known for playing Mike “Meathead” Stivic on the CBS sitcom “All in the Family” (1971–1979), a role that earned him two Primetime Emmy Awards.

Rob’s other acting credits include Throw Momma from the Train (1987), Sleepless in Seattle (1993), The First Wives Club (1996), and The Wolf of Wall Street (2013), among other films.

Rob made his directorial debut with the heavy metal film This Is Spinal Tap in 1984. He went on direct the coming-of-age drama Stand by Me in 1986, The Princess Bride (1987), When Harry Met Sally… (1989), Misery (1990), A Few Good Men (1992), and The American President (1995). He earned multiple nominations for his directing.

In 2015, the Reiner family’s drama film “Being Charlie” premiered at TIFF.

Nick co-wrote the script with a friend from rehab. The movie drew on the individual family dynamics that led them to abuse drugs.

Rob directed the movie.

The character Charlie (based on Nick) resented his father and mother for forcing him into rehab to treat his addiction.

According to The Hollywood Reporter, the film offered few answers and ended with a contrite apology from the father for the unsympathetic way he treated his son.
