At an arraignment at the Los Angeles County Superior Court on February 23, Rob Reiner and Michele Singer Reiner's son Nick Reiner pled "not guilty" to two counts of murder.
The 32-year-old has been criminally charged with the deaths of his parents, who were found in their Brentwood home on December 14, 2025, with special circumstances related to multiple homicides.
What happens next? We spoke with former Los Angeles County deputy district attorney, now criminal defense attorney RJ Dreiling, of Dreiling Law APC, about the case moving forward…

"In any criminal case, unless there is a settlement, the prosecutor must take the case to trial," Dreiling told HELLO!. "In this case, the prosecutor would be using witnesses from Conan O'Brien's Christmas party to establish the motive against Reiner's parents, and then use a combination of forensic evidence, including DNA, and witness testimony to tie Nick Reiner to the scene of the murders."
A gripping situation
The tragic circumstances of the case add much more emotional heft to the trial, Dreiling noted as well, especially given how beloved the late Rob Reiner was, and the reputation that he and Michele had cultivated in Hollywood.

"On the other hand, many jurors are going to have a tough time believing that anyone in their right mind would do something like that, which is going to be the challenge for the prosecution."

There is a good chance that Nick's siblings, particularly his brother Jake and sister Romy, would be involved. "If Nick is found guilty, and there is a hearing on what kind of sentence he should receive, I would expect that his siblings will be afforded an opportunity to tell the judge what they think an appropriate sentence should be," Dreiling explained, especially given that it was allegedly Romy who first discovered their parents.
"If the case goes to trial, Nick Reiner is currently facing the death penalty under California law," Dreiling noted, although that could change depending upon the prosecution's request. They could change it to asking for life without parole, with the attorney deeming a death penalty ask "unlikely" given Nick's mental health issues.

Given Nick's case will go to trial, it is widely believed that his defense will opt for an insanity defense, wherein they aim to prove that their client was not of sound mind while committing said crime, thereby debunking the idea of the action being "premeditated."
The actor and writer's mental health struggles have been well-documented. He has spoken in the past of his experiences with rehabilitation facilities and reportedly was diagnosed with schizoaffective disorder weeks before his parents were killed.

They can use his history of mental health struggles to help bolster this claim."
