Dec. 17 2025, Published 6:09 p.m. ET
Nick Reiner, the troubled son of filmmaker Rob Reiner, has been branded by shocked insiders as the "most horrific nepo baby in Hollywood history" after being charged with murdering his parents in a knife attack that has left the industry reeling.
Rob Reiner, 78, and his wife Michele Singer Reiner, 68, were found dead in their Brentwood, Los Angeles, mansion on Sunday afternoon, with their throats slit as they lay in bed.
Tragedy at the Reiner Estate
Nick Reiner was charged with murdering his parents in a knife attack.
The discovery was made by their daughter Romy Reiner, 28. Nick, 32, who had recently moved back into a guesthouse on the property, was arrested later that night and now faces two counts of first-degree murder, with prosecutors saying the death penalty is a possibility if he is convicted.
The killings came hours after all three attended comedian Conan O'Brien's Christmas party in Pacific Palisades on Saturday night.
One attendee at the bash said: '"Nick was freaking everyone out, acting crazy."
Another guest added that his behavior was so erratic several people believed the self-confessed recovering drug addict had relapsed and was under the influence of drugs.
Sources added the tension culminated in a huge loud argument between Rob and his son that stopped conversations around the room.
Erratic Behavior at the Holiday Bash
Witnesses described Nick’s behavior as erratic at Conan O’Brien’s Christmas party.
Comedian Bill Hader was among those who encountered Nick's behavior firsthand.
A witness said Nick interrupted a private conversation the comic was having, and, after being told it was not the moment for an outburst, stared silently before storming off.
"It was unsettling," a guest said. "People were exchanging looks, wondering if someone should step in."
Friends added Rob and Michele had insisted on bringing Nick to the party because they were worried about his mental state and wanted to keep an eye on him.
Insiders say the argument centered on Nick's refusal to return to rehab, despite his parents' belief he needed urgent help.
"Rob was very scared," a family friend said. "He thought Nick was spiraling back into trouble again."
Arrest and Details of the Crime
Friends said Rob and Michele worried deeply about their son’s mental state.
Hours later, Rob and Michele were dead.
Authorities say Nick checked into a Santa Monica hotel around 4am, where staff later found a shower full of blood and bloodstains on the bed.
He was arrested at 9:15pm in Exposition Park and taken into custody without bail, reportedly placed on suicide watch.
L.A. County District Attorney Nathan Hochman said: "These charges will be two counts of first-degree murder with a special circumstance of multiple murders. He also faces a special allegation that he personally used a dangerous and deadly weapon, that being a knife."
He added: "No decision at this point has been made with respect to the death penalty."

'Insiders said the tragedy forced Hollywood to confront years of missed warning signs.
Nick has publicly detailed years of addiction, homelessness and anger, including multiple stints in rehab beginning at age 15.
In 2016, while promoting the semi-autobiographical film Being Charlie, which he co-wrote and Rob directed, his father reflected on their relationship, saying: "It forced us to understand ourselves better than we had. I told Nick while we were making it, I said, 'You know it doesn't matter, whatever happens to this thing, we won already.'"
As investigators continue piecing together the final hours before the killings, friends say the tragedy has ignited a grim reckoning in Hollywood about privilege, addiction, and years of warning signs that ended in irreversible violence.
Several insiders said Nick's conduct at O'Brien's party reflected a long-standing pattern tied to his privilege.
"He was born into Hollywood royalty and hated it, but he also never walked away from the money or safety net," a family friend said. "He went to rehab 18 times, destroyed property, and there were never real consequences."
Another source added: "He never smiled in family photos, never played the grateful son. He made a show of his resentment."
Sources also said about Nick's alleged refusal to return to rehab: "He told his parents he could do it his way at home.
"That's the privilege talking – thinking rules don't apply to you. Nick was always an unsmiling brat – truly one of Hollywood's worst nepo babies."
Another insider added: "Plenty of Hollywood's nepo babies have ended up junkies and disturbed.
"But Nick appears to be one of the worst cases in showbiz history, and that will be confirmed if he is convicted of killing his parents."
Erik Aude, a stuntman on Being Charlie, said Nick and Rob had at least one furious argument while making the film.
He also branded Nick a "nepo-baby" and "spoiled kid to the tee."
Aude added Rob couldn't "do anything right" in Nick's eyes. Nick's drug admissions have included a tale of how he once suffered a cocaine-induced heart attack on a plane, leading to him waking up in a hospital.
He also hurled a rock through the window of a rehab center to convince officials he needed medication.
Nick insisted in 2016 he had managed to stop taking heroin after realizing he comes from a "nice family."
He added: "I'm not supposed to be out there on the streets and in homeless shelters doing all these... things."
