Oscar-nominated filmmaker Rob Reiner and his wife, photographer and producer Michele Reiner, were tragically stabbed to death in their home on December 14. Not long after, their son, Nick Reiner, was arrested and charged with two counts of first-degree murder. Now, People is reporting that Nick was disciplined after he allegedly became “extremely hostile” toward deputies while waiting to be escorted back to his cell after a shower. Nick Reiner has spent the last seven months in isolation, the outlet had previously reported. “Nick no longer looks like Nick,” an insider close to the Reiner family told the Daily Mail in July 2026.
