Conan O'Brien at center of new details in Nick Reiner case as 911 call controversy emerges
Witnesses recount a tense confrontation at the comedian's Los Angeles Christmas party hours before Rob and Michele Reiner were found fatally stabbed; authorities say no 911 calls were made from O'Brien's home.
New details have emerged about a Christmas party hosted by comedian Conan O'Brien in Los Angeles, where guests said he intervened to prevent calling 911 during a confrontation between Rob Reiner and his son Nick. The dispute occurred at O'Brien's home on Saturday night, just hours before Rob, 78, and Michele Reiner, 70, were found dead at their Brentwood residence.
Multiple attendees described the confrontation as tense and loud, with one insider telling the Daily Mail that at least one guest suggested police intervention because of concerns about Nick's behavior. Another person said O'Brien stepped in and said, "it's my house, my party, I'm not calling the police." O'Brien did not respond to requests for comment via the Daily Mail. A second source corroborated the account, noting that partygoers had raised concerns about Nick's mental state before the intervention.
A spokesperson for the Los Angeles Police Department told the Daily Mail that there were no 911 calls from O'Brien's residence on Saturday night. The day after the party, Rob and Michele Reiner were discovered dead in their home; investigators say they were found with knife wounds in the early hours of Sunday. One insider said the couple’s daughter Romy, 27, found them around 3:30 p.m. Sunday after living nearby.
Nick Reiner, who had been living in his parents’ guest house amid a history of substance use and mental health challenges, was arrested about 9 p.m. Sunday roughly 15 miles from the Brentwood mansion. He has since been charged with two counts of first-degree murder and is being held without bail. Authorities described his behavior in the days leading up to the killings as deteriorating, with reports that he had been erratic and that doctors had recently adjusted his medication.
Various outlets have reported on the party and the subsequent investigation, including accounts that Nick interrupted a private conversation involving comedian Bill Hader, prompting tension at the event. NBC News and TMZ cited witnesses who described Nick as displaying antisocial behaviors during the evening. The Reiners’ representatives have publicly denied some of the sensationalized details reported in tabloid outlets, and law enforcement has cautioned that the investigation remains active. Authorities have emphasized that, at this stage, no motive has been released, and investigators are examining events surrounding the party as part of the broader case.
