Jake Reiner made his first public appearance since his parents Rob Reiner and Michele Reiner’s gruesome murders.

“Attended the premiere of ‘Life, Larry and the Pursuit of Unhappiness’ this week. Comes out Friday on @hbo @hbomax, look out for me in the first episode 🫡 🇺🇸,” he captioned snaps of himself on the red carpet Thursday.

For the premiere, Jake wore a black blazer, black trousers and a gray T-shirt.

Jake, 35, and his sister, Romy, 28, have largely been staying under the radar since the tragedy.

The longtime couple were murdered at their Los Angeles home, which is located in the Brentwood area, on Dec. 14. Rob and Michele were 78 and 70, respectively.

Their younger son, Nick, 32, was arrested as the prime suspect in the murders. He was hit with two separate charges for first-degree murder and is currently behind bars at Twin Towers Correctional Facility in Los Angeles. 

He pleaded not guilty at a February court hearing.

In April, Jake broke his silence on their deaths in a heartbreaking Substack essay, in which he detailed the exact moment he learned of his parents’ murders.

“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 said he feels “robbed of so many things” over losing his parents, 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,” Jake continued. “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.”

Later in the essay, Jake called his parents’ murders “horrific” and said that every day since then “has been horrendous.”

He eventually referenced Nick by saying that his brother is “at the center” of the tragedy.

“We lost more than half of our family that night in the most violent way imaginable,” Jake wrote. “It’s almost too impossible to process.”

Romy has yet to break her silence on the tragedy, but in his essay Jake noted that she “will tell [her story] in her own way and in her time.”

Jake and Romy first addressed Rob and Michele’s gruesome deaths in a heartbreaking statement to Page Six on Dec. 17 — without making any mention of Nick.

“Words cannot even begin to describe the unimaginable pain we are experiencing every moment of the day,” the brother and sister said. “The horrific and devastating loss of our parents, Rob and Michele Reiner, is something that no one should ever experience.”

They also asked “for respect and privacy” as they grieve their parents’ deaths privately.

They did not attend Nick’s Feb. 23 court hearing.

Nick struggled with drug addiction for years and was in and out of rehab. He was diagnosed with schizophrenia before his parents’ deaths.

If convicted, Nick faces a possible death sentence or life in prison without the possibility of parole.
