A stoic Nick Reiner appeared in Los Angeles Superior Court on Wednesday for a preliminary hearing setting in connection to the December 2025 murders of his parents, Rob Reiner and Michele Singer Reiner.

Nick, 32, wore a yellow prison jumpsuit and blue pants, sporting a shaved head and full beard. He did not smile as he sat emotionless beside Los Angeles County Deputy Public Defender Kimberly Greene, who took over the case in January after high-profile attorney Alan Jackson withdrew.

Nick maintained an icy stare as he mumbled his brief responses to Judge Samuel Ohta.

Greene explained that she and her team were still waiting on Rob and Michele’s autopsy reports, so Ohta extended the preliminary hearing setting to Sept. 15.

Nick was arrested by Los Angeles Police Department officers on Dec. 14, 2025, shortly after his dad and mom — who were 78 and 70, respectively — were found stabbed to death inside their Brentwood home.

Nick was charged with two counts of first-degree murder with special circumstances of multiple murders and personal use of a knife.

According to Rob and Michele’s death certificates, they died within “minutes” of receiving “multiple sharp force injuries” with a “knife, by another.”

If convicted, Nick — who has remained behind bars at Twin Towers Correctional Facility since his arrest — faces a possible death sentence or life in prison without the possibility of parole.

Nick — who had gotten into an argument with his parents at Conan O’Brien’s Dec. 13 Christmas party — was diagnosed with schizophrenia before the killings and has a long history of drug addiction.

He pleaded not guilty in February.

Rob and Michele, who had been married since 1989, were also parents to son Jake Reiner, 34 and daughter Romy Reiner, 28. Prior to marrying Michele, the actor-director was married to Penny Marshall from 1971 to 1981. During their relationship, Rob adopted her daughter, Tracy Reiner, 61.

Jake broke his silence on his parents’ deaths last week in a Substack essay that detailed the exact moment he found out they had died.

“I was in Union Station at a celebration of life for one of my best friends, Christian Anderson, who died in October,” Jake wrote. “It was at that moment I received a call from my sister Romy telling me our father was dead. Minutes later, she called back telling me our mother was also dead.”

Jake continued, “The 45-minute Lyft ride from downtown to the west side was unendurable. My world, as I knew it, had collapsed. I was in a trance. The only thing I could focus on was that I needed to get to my childhood home. I needed to get to my sister. I needed to figure out what the hell just happened.”

Jake lamented that he feels “robbed of so many things” after losing his dad and mom, noting that the tragedy “simultaneously breaks my heart and enrages me.”

“Nothing can prepare you for what it feels like to lose both parents instantly at the same time,” he added. “It’s too devastating to comprehend. I still wake up every morning having to convince myself that, no, it’s not a dream. This truly is my living nightmare.”
