Nick Reiner, the 32-year-old son of filmmaker Rob Reiner, allegedly lost control in a jail shower on April 27 and had his phone, visitor, and commissary privileges stripped for five days, the latest sign of trouble as he awaits trial for the stabbing deaths of both parents.
Reiner had finished showering and changing at Twin Towers Correctional Facility in Los Angeles when deputies failed to return him promptly to his cell. Another inmate had apparently overdosed nearby, pulling staff away. That delay set Reiner off. An insider told People that Reiner began yelling, screaming, and directing profanities at a sheriff and a sergeant assigned to the specialized medical observation unit where he is held in solitary confinement.
The outburst stayed verbal, no physical confrontation followed, but one deputy called for reinforcements, and three additional guards arrived at the shower area. Jail staff issued a disciplinary write-up. A supervising officer reviewed it, and a disciplinary officer later visited Reiner's 7-by-10-foot cell to inform him of the violation and the penalties: no commissary access, no phone calls, and no visitation for five days.
The source who spoke to People did not hold back about the episode. As the Daily Mail reported, the insider characterized Reiner's conduct in blunt terms:
"He was recalcitrant, extremely hostile, creating a verbal disturbance, refusing to follow rules and not listening to any commands."
The same source said Reiner "had finished showering and changed and wanted to return to his cell. When it took too long, he became frustrated and angry." He grew "upset and hostile because no one was coming back right away and he wasn't attended to."
Reiner is housed alone in the facility's medical observation unit, subject to a wellness check every 15 minutes. Deputies escort him individually to a locked steel shower, a level of supervision that underscores both the severity of the charges and concerns about his mental state.
The shower blowup fits a broader pattern described by someone close to the Reiner family. That source told the Daily Mail that Nick has been "rapidly deteriorating" in custody, becoming "like a babbling child, totally out of it" to the point that "his lawyers have a hard time talking to him." Reiner has reportedly been diagnosed with schizophrenia and has a history of substance abuse, though neither diagnosis has been confirmed through court or medical records in any public filing.
His legal representation has already shifted once. Attorney Alan Jackson, who successfully prosecuted music producer Phil Spector for murder and later defended Kevin Spacey and Harvey Weinstein in private practice, withdrew from the case on January 7. Jackson cited "circumstances beyond our control" and "beyond Nick's control" but offered no further explanation. When asked who had been paying his fees, Jackson said only, "I can't comment."
Public defender Kimberly Greene now represents Reiner. His preliminary hearing is scheduled for September 15.
Nick Reiner faces two counts of first-degree murder and has pleaded not guilty. If convicted, he could face life in prison without the possibility of parole or the death penalty.
Rob and Michele Reiner were found stabbed to death on December 14, 2025, at their $13.5 million Brentwood estate in Los Angeles, the same property where Nick lived in a guesthouse on the grounds. The evening before the bodies were discovered, Nick was allegedly seen arguing fiercely with his parents at a Christmas party hosted by Conan O'Brien. His sister Romy, 28, who lived across the street from the estate, allegedly witnessed the confrontation.
The Los Angeles County District Attorney's office declined the Daily Mail's request for comment. Nick's current counsel also declined to comment.
Until recently, Nick had received no personal visitors other than his lawyers. A source said that on a recent Monday, someone described as "a relative" visited him in the presence of his counsel, the first such visit since his arrest.
Months remain before the September preliminary hearing, and significant gaps persist. No one has publicly explained the "circumstances" that forced Alan Jackson off the case, or who was funding his defense before the switch to a public defender. Whether Nick Reiner's reported mental decline has been formally evaluated by any court-appointed clinician is unknown. And the specific jail violation cited in the April 27 write-up has not been disclosed beyond the general description of his conduct.
The DA's office is not talking. The defense is not talking. The only voices on the record are unnamed insiders painting a picture of a man unraveling inside a 7-by-10-foot cell, and a legal system that will not reach his case for months.
When a defendant's own lawyers reportedly struggle to hold a conversation with him, the question is not whether the system is watching closely enough. It is whether anyone with authority is prepared to act on what they are seeing.
