Nick Reiner's Conan O'Brien Party Behavior: What Witnesses Saw Hours Before the Murders

What happened at Conan O'Brien's Christmas party on December 13th may become key testimony in the case against Nick Reiner. Multiple witnesses have described Nick's behavior that night in detail: he approached guests with repetitive questions—"What's your name? What's your last name? Are you famous?"—stood and stared when asked to leave conversations, interrupted comedian Bill Hader mid-conversation, and wore a hoodie while everyone else was in formal attire. One source said he was "freaking everyone out." The evening ended with what witnesses described as a "very loud argument" between Nick and his father, Rob Reiner, over his conduct. By the next morning, Rob, 78, and Michele Singer Reiner, 70, were dead—stabbed multiple times in the master bedroom of their Brentwood home. Their daughter Romy discovered her father's body. Nick was arrested that evening near USC and charged with two counts of first-degree murder with special circumstances. His attorney Alan Jackson has since withdrawn from the case while insisting Nick is "not guilty of murder" under California law. Nick has a documented history of schizoaffective disorder and an eighteen-stint rehab history. Sources say he had recently changed psychiatric medications. His arraignment is now set for February 23rd.#NickReiner #RobReiner #MicheleSingerReiner #ConanOBrien #ReinerMurders #BrentwoodMurder #HollywoodTragedy #MentalHealthCrisis #ReinerCase #TrueCrimeJoin Our SubStack For AD-FREE ADVANCE EPISODES & EXTRAS!: https://hiddenkillers.substack.com/Want to comment and watch this podcast as a video?
