In the hours before he allegedly murdered his parents, Nick Reiner reportedly made a nuisance of himself at Conan O’Brien’s holiday bash, repeatedly pestering A-list guests with three bizarre questions before being shown the door.

The 32-year-old now faces two murder charges after allegedly stabbing Rob Reiner, 78, and Michele Singer Reiner, 68, at their Los Angeles residence, mere hours after the trio attended the star-studded celebration where Nick had allegedly been harassing celebrities with his persistent questioning.

Following earlier reports that his behavior at O’Brien’s party, which had several A-list Hollywood attendees, fresh details have emerged about the nature of his interrogations as he made his rounds among partygoers.

Sources indicate that as he moved from guest to guest at the gathering, Nick repeatedly posed the same trio of questions.

His conduct ultimately resulted in him being escorted from the event, reports the Express US.

The Wall Street Journal reports that Nick persistently grilled fellow attendees about their celebrity status and identities.

“What’s your name? What’s your last name? Are you famous?” he allegedly asked.

Among the stars he allegedly confronted was Bill Hader, following an earlier introduction facilitated by his father. The encounter turned uncomfortable when Hader rebuked him for interrupting him while he was in “the middle of a private conversation.

“Nick just stood there and stared before storming off,” an insider previously told NBC News.

In the wake of the shocking news that Rob and Michele were found fatally stabbed in their residence less than a day later, Hader, 47, was spotted outside his own home, nervously pacing during a phone call.

The couple was discovered in their home on Sunday afternoon, December 14, after their daughter, Romy, 27, went to check on them when a massage therapist arrived for a prearranged appointment but couldn’t gain entry.

It’s claimed that she ran from the scene after finding her father, then phoned Billy Crystal, her father’s longtime friend, while her roommate dialed 911. She later found out about her mother’s death inside the house when paramedics arrived at the scene and delivered the tragic news.

Nick was apprehended later that day and has since been indicted with two counts of first-degree murder.
