Conan O’Brien Stopped 911 Call As Nick Reiner’s Explosive Fight With Dad Terrified Guests At Party
Conan O’Brien reportedly intervened to stop guests from calling 911 during a heated argument between Nick Reiner and his parents, filmmaker Rob Reiner and photographer Michele Singer Reiner, at the comedian’s holiday party.
On December 13, Nick attended the Christmas party with his parents, where his behavior grew increasingly alarming and erratic. The volatile confrontation prompted attendees to call the police and even request a psychiatric hold.
- Conan O’Brien allegedly stopped guests from calling 911 during Nick Reiner’s explosive argument with his father.
- Rob Reiner reportedly told partygoers he was “petrified” of his son hours before his death.
- Nick’s erratic behavior also unsettled guests, including actor Bill Hader.
- Nick had been diagnosed with schizophrenia weeks earlier and is now charged with double homicide.
However, O’Brien stepped in, saying, “It’s my house, my party, I’m not calling the police.” He talked the guests out of contacting authorities.
Rob and Michele were found lifeless on December 14, and their demise was ruled a homicide. Nick was arrested with two counts of first-degree murder.

Sources told theDaily Mailthat Nick’s confrontation with his father became so distressing and scary that partygoers decided to call the police.
“They got in an argument, the father and son [at the party]. It got so bad and loud [that] someone wanted to call the police to report it,” one insider said.
Another source revealed some guests got worried about whether Nick should be placed on a psychiatric hold due to his behavior.

“When the s–t was hitting the fan, somebody said, ‘We need to call the police.’ The conversation was about getting this kid put into a mental-health hold.”
But Conan O’Brien intervened and told the guests not to call the police, since it was his house and his party. While some guests understood the desire to avoid a public scene, the squabble between Nick and Rob was described as “pretty intense.”

Hours before Rob Reiner was found slain at his home, the director known for When Harry Met Sally expressed fear that his son might harm him.
Asreported by Bored Panda, an unspecified celebrity shared with The Daily Mail the final words of the director at the party.
“I’m petrified of [Nick]. I can’t believe I’m going to say this, but I’m afraid of my son. I think my own son can hurt me.”

Rob’s friends also revealed that he and Michele were “scared for Nick” and his deteriorating mental health. The couple brought him to the party as they were reluctant to leave him alone.
Nick was arrested five hours after his parents were found deceased. He is currently serving at the Twin Towers Correctional Facility in Los Angeles.

Nick’s behavior at the Christmas party not only unsettled his parents but also several other guests. Sources revealed to People that Nick was behaving “creepily” at the party.
“Nick was freaking everyone out, acting crazy, kept asking people if they were famous.”
According to NBC News, Wall Street Journal, and TMZ, Nick also had an interaction with actor Bill Hader. One source claimed that he reportedly interrupted a private conversation Hader was having with others.

“What’s your name? What’s your last name? Are you famous?” Nick asked.
When Hader told him the discussion was private, Nick froze, stared at him before “storming off.”
The source further stated that Nick stood out at the party enough to alarm the guests.

Asreported by Bored Panda, Nick was diagnosed with schizophrenia weeks before he allegedly stabbed his parents in their Brentwood home.
According to TMZ, doctors had recently adjusted his medications to stabilize him, which led him to behave “erratic and dangerous.”
A source told the outlet, “Nick was out of his head.”
Nick also spent time at a Los Angeles rehab facility specializing in mental illness and substance abuse. Sources also described him as a “ticking time b*mb”, who would not sleep for days.

“His dr*g use was getting worse and his parents wanted him out.”
Nick had been living at his parents’ guest house and visited the rehab almost 20 times.
Even during his first court appearance on December 17, he appeared stoic and only spoke three words, “Yes, your honor.”
He is expected to plead not guilty by reason of insanity. Nick’s arraignment is scheduled for January 7, 2026.
“Hoping Conan is taking this ok. This whole thing was not his fault whatsoever,” one user sympathized the comedian

Poll Question
Thanks! Check out the results:
Difficult choice, but a bad option taken in the end. I'm sure he does feel guilty about it now.
We are far from rich celebrities, but in my neighborhood if you call the Aurora PD, they just make the situation worse. Yes it's that Aurora, the ones who unalived Elijah McClain. Despite being under a consent decree, the APD is still trigger happy AF especially if it's involving a minority. My neighborhood is not the best. They don't even respond to most reports of gunfire. I am 1.5 blocks away from E Colfax (IYKYK) and there was a drive by and the truck (driven by sh00ter) careened down my street and crashed into an apartment building right across the street. Then fled on foot. It took the APD 90 minutes to respond. I timed them. The other day, my neighbors were outside screaming at each other and the woman was naked. Their sidewalk is right over the chain link fence at my bedroom window. I got to see and hear the whole thing. Notably no one in my Barrio called the cops. If I saw them start to physically hurt each other, I would have probably called though.
Load More Replies...I worked in a psychiatric unit. I think the police would have possibly escorted Nick out, but they would only have had him “cool off” overnight , if at all. Then he would have gone to their house, same result. The Reiners may have also just gone home, taking Nick, same result. If Nick left on his own volition after police warnings, he would have waited in their house, same result. I think none of the actions would have changed the outcome.
It’s much easier (in the UK at least) if someone is having a mental breakdown in public and they can be sectioned quickly for up to 24 hours (section 136 Mental Health Act). Please don’t listen to whoever wrote the police wouldn’t help. From a former police officer.
Exactly. I call the police regularly when my neighbors are having freak-outs and every single time (more than two dozen in time years), they’ve had EMTs take ‘em for 72-hour holds. The police don’t decide “Ah, he’s just irritated; once he gets some sleep, he’ll be okay.” They know to get the people acting crazily away from us innocent folks so we’re not harmed.
Load More Replies...He should have called the police. Police in the US are trained to de-escalate situations like this with their firearms.
... what, by killing him? (Not being facetious. I don't see how one can de-escalate a situation by producing a gun.)
Load More Replies...Conan might want to check ahead and see if Andy D**k has any room in his RV. Because I think Conan is about to go through some things.
Poor Conan, I bet he really regrets that. Hopefully he can get into therapy to battle that regret.
It's somewhat amazing how much the general public doesn't care about this story. Conan O'Brien isn't good in a crisis so expecting him to do the right thing seems reaching. I see the comments attempting to shame Conan but it reads more like Conan hoping to get PR mentions in news. It is unlikely police would have taken the person into a psych hold anyway. So much about this story seems manufactured. All the news reports are vague without details. Words like sources and executive are not descriptive. It's a terrible tragedy but none of us should know any of these Hollywood people so have a Merry Christmas everyone.
Forget who the person is. It's common sense, a bad situation arises then what do you do. If he's in his position then he should think of the general issue. He f****d up simple as and his decision was obviously of his own reputation and image. Comments can shame but his actions did enough. If you was a bystander witnessing a bad issue that makes you want to call the police, and an individual with a status told you to not call them what would you do?!?! Follow your gut or do as you're told like a scolded child??!?!
Load More Replies...Hindsight is 20/20, and often calling the police only escalates the situation. I actually experienced something a bit similar to this in that two of my neighbours kept getting into extremely loud and disturbing arguments. People looked the other way because none of us wanted to get involved. When I finally did call the cops it was because it actively sounded like very real violence was going down. Whether it was I don't know, but even then it took a lot of persuasion from my friend I was messaging with before I finally went ahead with it.
It's not Conan 0'Briens call to not let his guests call 911. I hope the guilt from this tragedy follows him forever.
He didn't want to ruin a family's night by calling the police on their son around Christmas. It wasn't an image thing.
