Who Is Rob Reiner’s Son Nick Reiner?
Nick Reiner, 32, is the son of the late filmmaker Rob Reiner and Michele Singer Reiner. He has recently become the focus of an active Los Angeles homicide investigation after authorities arrested him in connection with the stabbing deaths of his parents at their Brentwood home.
Family Background and Early Life
Nick Reiner was born in 1993, the middle child of Rob Reiner and Michele Singer Reiner, and grew up in a family deeply rooted in the entertainment industry. His father was a celebrated director and actor, known for landmark films such as When Harry Met Sally…, The Princess Bride, and This Is Spinal Tap. His mother was a photographer and the couple had three children together: Jake, Nick, and Romy.
Nick also has an older sister and a younger brother, and his father was earlier married to Penny Marshall, with whom he adopted actress Tracy Reiner.
Struggles With Addiction and Rehab
Reiner’s life has been marked by public accounts of his long battle with drug addiction and homelessness, struggles he faced in his teens and early adulthood. His first rehab stint reportedly began around his 15th birthday, and by age 22 he had been through numerous treatment programs. At times, Nick chose homelessness over returning to rehab, living on the streets in various states as part of his difficult journey toward recovery.
In interviews years ago, Nick described how these experiences shaped him, and he worked to stay clean and rebuild his life with the support of his family.
Collaboration With His Father on Being Charlie
Much of what Nick experienced informed his work as a screenwriter. In 2015, he co-wrote the semi-autobiographical film Being Charlie with co-writer Matt Elisofon. Directed by his father, the film tells the story of an 18-year-old navigating drug addiction and treatment while dealing with tensions involving his family—elements drawn from Nick’s real-life experiences.
The movie premiered at the Toronto International Film Festival in 2015 and was released the following year. It starred Nick Robinson as the troubled young man and explored the emotional complexities of addiction, drawing partly from Nick’s own history.
Arrest and Ongoing Murder Investigation
On Dec. 14, 2025, Rob Reiner and Michele Singer Reiner were found stabbed to death inside their Brentwood residence. Their daughter found their bodies, which Los Angeles police said showed injuries consistent with homicide.
Law enforcement subsequently took Nick Reiner into custody in connection with the deaths. According to multiple news outlets, he has been booked on suspicion of murder, with bail set at $4 million. Police confirmed that detectives from the LAPD’s Robbery-Homicide Division are leading the investigation and currently are not seeking any additional suspects.
Nick’s arrest came after initial reports indicated family turmoil and a stabbing incident inside the home. Authorities found no evidence of forced entry, and investigators have described Nick’s detention as connected directly to the couple’s deaths.
At this stage legal proceedings will continue and prosecutors have not yet provided detailed information on motive or filed formal charges in court. The investigation remains active, and law enforcement continues to gather evidence as the case moves forward.
Personal Public Profile
Despite his famous family, Nick largely kept a low public profile before the recent events. He did not maintain an active social media presence and was primarily known within industry circles for his collaboration on Being Charlie and his occasional appearances at family film events.
His history of addiction and efforts to turn his life around were openly discussed in past interviews related to Being Charlie, where he acknowledged the challenges of rehab and homelessness and the personal growth that came from confronting those struggles. However, the devastating circumstances surrounding his parents’ deaths have now thrust him into the center of a highly scrutinized criminal investigation, overshadowing the earlier chapters of his life.
As authorities continue the investigation, court filings and further developments are expected to shed more light on the events leading up to this tragic episode.
