Rob and Michele Reiner Warned About Son Nick's 'Erratic' Behavior Before Murders

Medical staff advised the couple not to let their mentally ill son live at home after a medication change, but they kept him close.

According to reports, Rob Reiner, the acclaimed filmmaker, and his wife Michele were warned by medical staff not to let their son Nick, who has schizoaffective disorder, live with them at their Brentwood home after a change in his psychiatric medication, just weeks before the couple were found stabbed to death in December 2025. Despite the warnings, Nick was living in a guesthouse on the family's property at the time of the murders.

Why it matters

This tragic case highlights the challenges families face in caring for loved ones with severe mental illness, and the difficult decisions they must sometimes make to balance safety and compassion. It also raises questions about the role of medical professionals in advising families and the need for better support systems for those struggling with mental health issues.

The details

Nick Reiner, 32, had been diagnosed with schizoaffective disorder in 2020, a condition that can cause hallucinations, delusions, and severe mood swings. Weeks before the alleged murders, he asked his doctor for help with weight gain, a common side effect of some psychiatric drugs, and his medication was changed. Medical staff reportedly warned Rob and Michele Reiner that Nick could exhibit 'even more erratic behavior' as his body adjusted to the new medication and advised them not to let him live at home. Despite these warnings, Nick was living in a guesthouse on the family's Brentwood property at the time of the killings.

  • In the weeks before the deaths in December 2025, Nick Reiner fired his psychiatrist and changed medication because it 'weren't working anymore'.
  • On December 14, 2025, Rob and Michele Reiner were found stabbed to death in their Brentwood home.
  • On February 23, 2026, Nick Reiner appeared in court and pleaded not guilty to two counts of first-degree murder.
  • Nick Reiner's next hearing is scheduled for April 29, 2026.
