**Rob Reiner and Wife Michele Brutally Killed After Heated Argument with Son at Conan O’Brien’s Christmas Party**

*Published: December 19, 2025, 5:27 p.m. ET*

Reports have emerged revealing that a violent altercation between Rob Reiner and his deeply troubled son Nick at Conan O’Brien’s Christmas party led at least one guest to desperately urge calling the police. However, Conan O’Brien reportedly declined, not wanting law enforcement to disrupt the holiday festivities at his home.

According to RadarOnline.com, the former talk show host reportedly shot down the suggestion, saying, “It’s my house, my party, I’m not calling the police.” Hours later, tragically, Nick allegedly brutally murdered Rob and his wife, Michele, in their Brentwood, California mansion.

### The Confrontation: “I’m Not Calling the Police”

An insider told the *Daily Mail* on December 19, “They got into an argument, the father and son. It got so bad and loud that someone wanted to call the police to report it.”

The source continued, “But Conan stepped in and said, ‘It’s my house, my party, I’m not calling the police.’ He talked them out of calling the police.”

Another insider added, “When the s— 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. Conan O’Brien stepped in and said, ‘No, I don’t want the police at my house.’”

An additional guest commented on O’Brien’s stance, saying, “It makes sense; who wants the cops showing up, creating a scene?” However, the same insider noted, “But the argument between Rob and Nick was pretty intense.”

### Troubled Son’s Behavior Causes Concern

Rob and Michele reportedly brought Nick to the star-studded bash out of fear of leaving him home alone amid a reported decline in his mental health.

Party guests were reportedly “freaked out” by Nick’s disturbing and antisocial behavior, including repeatedly asking A-list attendees if they were “famous.” One tense exchange reportedly occurred between Nick and comedian-actor Bill Hader.

This behavior prompted Rob Reiner, director of *When Harry Met Sally*, to pull his son aside to address his “asocial and unsettling behavior,” which escalated into a loud argument audible to other guests, causing the room to fall silent.

### Aftermath: Nick’s Whereabouts After Leaving the Party

Rob and Michele apologized to O’Brien for the disruption and left the party early. Nick’s whereabouts afterward are unclear.

Surveillance footage reportedly captured Nick walking past a gas station about two miles from the family home shortly after midnight. Later, a “tweaked out” Nick checked into the Pierside Hotel in Santa Monica around 4 a.m.

Hotel housekeeping reportedly discovered a shower “full of blood” and bloody bedsheets the following morning.

### Family Friend Disputes Severity of Incident

A close family friend was unable to confirm or deny the alleged fight at the holiday party but suggested the situation was “misinterpreted” and “overblown.”

The friend also took offense to claims that the argument forced the couple to leave the party early, stating that Rob had “grown used to” Nick’s behavior over the years, making such a departure unlikely.

### Tragic Discovery and Arrest

The next day, the lifeless bodies of Rob and Michele Reiner were found by their daughter, Romy, around 3:30 p.m.

Nick was arrested approximately five hours later, about 20 miles away, at a convenience store in LA’s Exposition Park area.

### The Devastating Impact on Conan O’Brien

An insider expressed sympathy for O’Brien, hoping he isn’t blaming himself for not calling the police and potentially de-escalating the situation or having Nick taken into custody for a mental health hold.

They stated, “Only the murderer is responsible. But it must be gut-wrenching for Conan to learn that this is how things turned out. I’m sure that night is replaying for him over and over. It’s just so awful and sad.”

### Nick’s History of Mental Illness and Substance Abuse

Reports have surfaced that Nick Reiner, who had a long history of drug abuse and mental illness, was diagnosed with schizophrenia prior to the alleged killing of his parents.

One insider revealed, “Nick was out of his head,” noting that his medication had recently been changed.
