In a chilling echo from the past, old podcast confessions from Nick Reiner – the 32-year-old charged with stabbing his famous parents, director Rob Reiner and photographer Michele Singer Reiner, to death – are resurfacing, painting a picture of a deeply troubled young man whose desperate bids for medication once led to extreme acts that stunned even seasoned rehab staff.

Sources close to the investigation confirmed this week that Nick had been diagnosed with schizophrenia years earlier and was undergoing treatment with antipsychotic medication. Critically, his dosage or type of drug had been adjusted or changed in the period leading up to the December 14, 2025, killings – a switch that reportedly left him “erratic and dangerous,” according to insiders speaking to outlets like TMZ and NBC Los Angeles.

The revelation has added a devastating layer to an already unthinkable tragedy that has rocked Hollywood and beyond. Rob Reiner, 78, the iconic force behind classics like “The Princess Bride,” “When Harry Met Sally,” and “This Is Spinal Tap,” and his wife Michele, 70, a talented photographer and producer, were found dead in their upscale Brentwood home from multiple sharp force injuries, ruled a homicide by the Los Angeles County Medical Examiner.

Nick Reiner was arrested hours later in the University Park area near USC, about 15 miles from the scene, after police used cellphone data, geotracking, and surveillance footage to locate him. He has been charged with two counts of first-degree murder with special circumstances of multiple murders and use of a deadly weapon (a knife), making him eligible for life without parole or the death penalty. Los Angeles County District Attorney Nathan Hochman has not yet decided on pursuing capital punishment.

The case took a grim turn when details emerged of Nick’s long battle with addiction and mental health. As a teenager, he spiraled into heroin and cocaine use, entering his first rehab around age 15 and cycling through at least 18 facilities by his early 20s – sometimes choosing homelessness over programs he felt didn’t work.

In a 2016 appearance on an addiction podcast, Nick openly recounted one jaw-dropping incident: Desperate for more medication during a stint in treatment, he picked up a rock and hurled it through a facility window to convince staff he was unstable enough to require heavier dosing. “I was so lost – I didn’t know anything about myself or the world,” he said. “And that’s all I knew as a coping mechanism.”

Rehab veterans quoted in reports described the act as one of the more extreme manipulation tactics they’d witnessed, born from a place of profound desperation rather than malice. But in light of the current charges, that story has taken on a haunting new resonance.

Rob and Michele Reiner were tireless in their efforts to help their son. In interviews promoting the 2015 semi-autobiographical film “Being Charlie” – which Rob directed and Nick co-wrote – the couple admitted they often sided with counselors over Nick’s pleas that certain programs weren’t helping. “We were desperate, and because the people had diplomas on their wall, we listened to them when we should have been listening to our son,” Rob told the Los Angeles Times at the Toronto International Film Festival.

Michele echoed the regret: “We were so influenced by these people. They would tell us he’s a liar, that he was trying to manipulate us. And we believed them.”

The film depicted a young addict’s chaotic journey, including scenes of street homelessness and family strife that mirrored Nick’s real life. By then, he had achieved sobriety and praised his parents for supporting his recovery. The project seemed a cathartic turning point, with Nick moving back to Los Angeles and even attending red-carpet events with the family, including the September 2025 premiere of “Spinal Tap II.”

But sources say underlying mental health issues persisted. Nick was diagnosed with schizophrenia several years ago, requiring lifelong medication to manage symptoms like hallucinations, delusions, and disorganized thinking. The recent adjustment – exact details of which drug or timeline remain sealed – reportedly destabilized him severely.

“He was out of his head,” one source told TMZ, adding that the change contributed to antisocial and alarming behavior in the weeks prior.

Witnesses at a holiday party hosted by comedian Conan O’Brien on Saturday, December 13 – the night before the bodies were discovered – described Nick acting strangely: hovering on the fringes, staring blankly, and getting into a heated argument with his father. Some guests found his demeanor unnerving.

The next morning, a massage therapist arrived for Michele’s appointment but got no answer at the gate. She contacted the Reiners’ daughter, Romy, 27, who lives nearby. Romy discovered the horrific scene and had a friend call 911.

Nick, who had been living in the family’s guesthouse, fled the property. The murder weapon has not been recovered, though investigators say its absence holds little evidentiary weight given other proof, including possible statements from the suspect.

In court appearances, Nick has worn a blue suicide-prevention smock, and a sealed medical order was issued early in the proceedings, likely related to his ongoing psychiatric needs. His arraignment was delayed after he was deemed not medically cleared to appear.

Siblings Jake Reiner, 34, and Romy broke their silence on December 17 with a heartbreaking statement: “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.”

The family has requested privacy as they grieve, while Hollywood figures from Jerry O’Connell to Corey Feldman paid tribute to Rob as a mentor and father figure.

Mental health experts, while not commenting specifically on the case, note that schizophrenia treatment often involves trial-and-error with medications, and abrupt changes can exacerbate symptoms or trigger crises. Substance abuse history can further complicate diagnosis and management, sometimes masking or mimicking psychiatric conditions.

The tragedy has reignited discussions about America’s addiction treatment system, with some pointing to Nick’s 18+ rehab stints as evidence of its failures for severe cases. Others highlight the challenges families face navigating mental health care for adult children.

Prosecutors have emphasized the brutality of the crime, with death certificates revealing the couple died within minutes of sustaining multiple knife wounds. No motive has been officially disclosed, but the combination of recent medication instability, historical struggles, and the prior night’s argument has fueled speculation.

Nick remains held without bail at Twin Towers Correctional Facility. His attorney, Alan Jackson, has indicated plans for an insanity plea, though no formal entry has been made.

As the investigation continues – with the knife still missing and forensic analysis ongoing – the Reiner case stands as a stark reminder of how addiction and untreated or poorly managed mental illness can devastate even the most privileged families.

Rob Reiner, a vocal political activist and Democratic heavyweight, and Michele, known for her warmth and artistic eye, leave behind a legacy of creativity, philanthropy, and unwavering parental devotion. Friends say they never gave up on Nick, pouring resources into his recovery right up to the end.

In the podcast where he described the rock-throwing incident, Nick reflected on his rock bottom with raw honesty. Nearly a decade later, that desperation has collided with unimaginable horror, leaving a community searching for answers in the shadows of Tinseltown’s brightest lights.
