Nick Reiner Diagnosed With Schizophrenia Before Parents Were Killed: Report

Nick Reiner, the son of legendary Hollywood director Rob Reiner and Michele Reiner, was reportedly diagnosed with schizophrenia just weeks before he allegedly killed his parents and had been placed on a new medication, which made him “erratic and dangerous.”

A long-time drug addict who was frequently in rehab, Nick Reiner, 32, had been seeing a psychiatrist when his behavior had grown “alarming” after his medication was changed three to four weeks before the couple was found with their throats slit in their Los Angeles home. According to a TMZ report, the new meds drove Reiner “out of his head.”

“Our sources say doctors were trying to adjust the medications so Nick stabilized, but it wasn’t working,” the outlet reported. “Our sources also say Nick’s substance abuse was worsening the schizophrenia.”

Reiner had been receiving costly care at a Los Angeles rehab facility, with a monthly charge of $70,000, the report said.

The additional information on Reiner’s mental state comes just days after he was charged with two counts of first-degree murder, with special circumstances attached since there were multiple murders and he allegedly attacked with a deadly weapon.

Nick Reiner’s two siblings — Romy, 28, and Jake, 34 — issued a statement after their brother’s first court appearance: “Words cannot even begin to describe the unimaginable pain we are experiencing every moment of the day. The horrific and devastating loss of our parents, Rob and Michele Reiner, is something that no one should ever experience. They weren’t just our parents; they were our best friends.”

Reiner, who was arrested hours after his parents’ bodies were discovered, did not enter a plea. After confirming that he understood he was waiving his right to a speedy arraignment, the judge granted a continuance, rescheduling the proceeding for Jan. 7, 2026.

He has retained high-powered defense attorney Alan Jackson, whose past clients include actor Kevin Spacey and disgraced movie mogul Harvey Weinstein.
