Nick Reiner’s Mental Decline | The Hollywood Homicide of Rob Reiner and Michele Singer

Tonight’s livestream examines the reported mental decline of Nick Reiner in the days, months, and years leading up to the brutal killings of Rob Reiner and Michele Singer. Drawing on recent reporting, witness accounts from inside the hotel, and disturbing details about Nick’s behavior before and after the murders, we'll take a closer look at what those around him observed, what warning signs may have been missed, and how his apparent deterioration fits into the broader timeline of the case.

Case Background:
Rob Reiner, the acclaimed Hollywood director and actor, and his wife, Michele Singer Reiner, a prominent photographer and producer, were found stabbed to death in their Brentwood, Los Angeles home on Sunday, December 14, 2025. Their daughter, Romy Reiner, discovered their bodies after first responders were called to the residence in the afternoon. The Los Angeles County Medical Examiner ruled their deaths homicides, caused by multiple sharp force injuries. Their 32-year-old son, Nick Reiner, was arrested later that same day and has been charged with two counts of first-degree murder in connection with his parents’ deaths. He is being held without bail, and prosecutors have noted special allegations related to multiple killings and the use of a deadly weapon.

Nick Reiner has a documented history of mental health struggles and substance abuse. In the weeks prior to the killings he was reportedly undergoing treatment for schizophrenia and addiction, with at least one adjustment to his psychiatric medications said to have contributed to unstable behavior, according to some sources.

Sources close to the family told reporters Rob and his son had been seen arguing the evening before the deaths, at a holiday gathering. Investigators believe the fatal stabbings occurred in the early morning hours of December 14, after which Nick reportedly left the scene before being located and arrested near the University of Southern California several hours later.
