Rob Reiner's son Jake has shared horrific new details of the day he found out his parents were murdered and the 'impossible' moment his brother Nick was charged with their slayings. 

Jake Reiner, 34, shared a gut-wrenching Substack article on Friday describing the moment he was told by his sister Romy, 29, that his parents had been found stabbed to death in their Los Angeles home in December 2025.

He said the news was 'too devastating to comprehend', and said he raced to his childhood home in a 45 minute taxi ride '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,' he wrote.  

'I was robbed of so many things that day. My parents won’t be at my wedding, they won’t get to hold their future grandchild, and they won’t get to see me have the successful career I’m still seeking. It simultaneously breaks my heart and enrages me.'

Jake said while reeling from the news of his parents deaths, he was horrified to then learn that his brother Nick was the alleged murderer. 

'We lost more than half of our family that night in the most violent way imaginable,' he wrote.

'Sure, any loss of a parent is devastating, but nothing compares to losing both of them at the same time and, on top of that, having your brother be at the center of it. It’s almost too impossible to process.'

Prosecutors allege that Nick, 32, attacked his parents in their home in Brentwood, Los Angeles on December 14, stabbing them to death with a knife before fleeing the scene. He has pleaded not guilty. 

Nick is facing two charges of first-degree murder, and is next due in court on April 29 for a discovery hearing on the evidence prosecutors will bring against him in his murder trial. He is being held in custody without bail.

In his Substack article shared Friday, Jake Reiner said he is still stunned almost six months on from the murders that a member of his own family allegedly killed his parents. 

'Every day since then has been horrendous,' he wrote. 

'Every meeting we take, every person we talk to, every tear we shed, every movement we make is connected to our parents being murdered.' 

Jake wrote of the anguish he and his sister Romy have endured since their parents' murders, while not mentioning Nick by name and only referring to him as 'my brother.'

He said he and his sister have continued suffering even as their parents' high-profile deaths left the spotlight, writing that 'when you are not living through a tragedy the specific way Romy and I are, it’s hard to wrap your head around just how horrific this has been.'

'Because they weren’t your parents, it might be easier to move forward or even forget for a moment about what happened that day,' he wrote.

'But for us, it’s every single day.'
