The night before Rob Reiner and Michele Singer Reiner were murdered, their son Nick Reiner attended Conan O’Brien’s holiday party and had a weird encounter with Bill Hader, sources told NBC News.

Nick Reiner was reportedly acting odd the night before his parents’ murders.

Indeed, the 32-year-old son joined Rob Reiner and Michele Singer Reiner at a holiday party hosted by Conan O’Brien on Dec. 13 and had at least one interaction that left attendees uncomfortable, two sources with knowledge of the situation told NBC News.

During the event, Nick interrupted a conversation Saturday Night Live alum Bill Hader was having with two guests, the sources said. Then, after Bill told him the conversation was private, Nick proceeded to stand still and stare before “storming off,” according to one source.

E! News has reached out to a rep for Bill for comment but has not yet heard back.

Beyond his interaction with the SNL star at the party, Nick was also seen getting into an argument with the When Harry Met Sally director and his wife, multiple sources told The Los Angeles Times and People.

Meanwhile, Jane Fonda revealed she too spent time with Rob and Michele the day before authorities say they were stabbed to death at their Los Angeles home Dec. 14.

“I saw them night before last looking healthy and happy,” the two-time Oscar winner wrote on Instagram Dec. 15. “I am reeling with grief. Stunned.”

Hours after the bodies of Rob, 78, and Michele, 70, were discovered, Nick was located and arrested on suspicion of their murders, according to a press release from the Los Angeles Police Department. He is currently being held without bail.

Following an investigation, Los Angeles County District Attorney Nathan Hochman announced that Nick would be formally charged with two counts of first-degree murder.

“He also faces a special allegation that he personally used a dangerous and deadly weapon, that being a knife,” the district attorney said during a Dec. 16 press conference. “These charges carry a maximum sentence of life in prison without the possibility of parole, or the death penalty.”

As for what the coming days will look like for Nick, Hochman explained that he would complete a medical clearance—standard practice for everyone arrested by the LAPD—and appear in court.

“Once he is medically cleared, he will be brought to court to be arraigned on these charges,” he shared. “At that point, he will enter a plea of guilty or not guilty.”

Lawyer Alan Jackson—who has previously represented Harvey Weinstein and Karen Read—confirmed to E! News Dec. 16 that he will be Nick’s attorney in the case and told reporters he would not be “commenting any further” beyond procedural details of the case.

Rob Reiner and Michele Singer Reiner’s Son Nick Reiner Details Struggle With Drugs

Years before Rob Reiner and Michele Singer Reiner’s tragic deaths, their son Nick Reiner shared that he struggled with addiction, even collaborating with his father on the 2015 film Being Charlie about substance abuse.

Nick explained that he had been to rehab 17 times before turning 30.

“I was homeless in Maine. I was homeless in New Jersey. I was homeless in Texas,” he told People in 2016. “I spent nights on the street. I spent weeks on the street. It was not fun.”

Two years later, Nick recalled an instance when he “wrecked” his home while high on drugs.

“I went 10 rounds in my guest house,” he shared on the Dopey podcast in 2018. “I got totally spun out on uppers—I think it was coke and something else—and I was up for days on end. I started punching out some things in my guest house.”
