REPORT: Friend Gives Inside Look at What Went on with the Beloved Reiners at Conan O’Brien’s Holiday Party

The night before their tragic passing, Rob Reiner and his wife, Michele Singer Reiner were at a holiday party at Conan O’Brien’s home with their son Nick, according to the Los Angeles Times.

“Family friends told The Times that Rob and Nick got into an argument on Saturday evening at a party at Conan O’Brien’s home and that many people noticed Nick acting strangely at the party,” the Los Angeles Times reported.

TMZ added that the actor and Nick got into a “very loud argument,” which was ” loud enough for many others to hear.”

“We’re told Rob and Michele then left the party,” they added. “We do not know if Nick left as well.”

Then, the day after the party, Reiner and his wife’s bodies were found dead inside their Brentwood home, with the two having suffered “lacerations consistent with a knife.” PEOPLE was the first to report that the two were killed by their son, Nick, going on to add that it was Rob and Michele’s daughter, Romy, who discovered their bodies.

What Exactly Happened At Conan O’Brien’s Holiday Party?

The New York Post provided some additional insight into the Holiday Party where the altercation between Reiner and his son first began, reporting that Nick “‘freaked out’ everyone and left Reiner terrified of what he would do next, pals said.”

The outlet added that the argument was “possibly because Nick was back on drugs and refusing yet another go at treatment after at least 17 stints in rehab since age 15, sources told The Post on Monday.”
