The Texas-raised attorney is representing Nick, who is accused of murdering Rob, his father and the film's director

The family instructor tried to make the best of his behavioral issues by channeling them into 'A Chair in the Air.'

Nick Reiner, who is accused of murdering his parents Rob Reiner and Michele Singer Reiner, will not be in court on Tuesday due to medical reasons, his attorney Alan Jackson said.

According to estate and trusts attorney Sean Weissbart, a partner at Blank Rome LLP who is not connected to the case, Nick will become ineligible to inherit from his parents' estate if he is ultimately convicted of the crime, per a particular state law.

The Los Angeles Deputy Police Chief Alan Hamilton said that Nick Reiner was arrested near the University of Southern California campus following the deaths of his parents, director Rob Reiner and his wife Michelle Singer Reiner.

The son of Rob and Michele Reiner has been accused of their murders and is currently being held in police custody without bail.
