Death certificates for Rob and Michele Reiner released after cremation process completed.

The tragic deaths of Hollywood couple Rob and Michele Reiner have garnered widespread attention, particularly following the release of their death certificates on Tuesday. According to documents obtained by Media News Source, the Reiners were cremated at Mount Sinai Mortuary. Their causes of death have been identified as “multiple sharp force injuries,” resulting from an attack with a knife by another party.

In a shocking turn of events, their 32-year-old son, Nick Reiner, has been arrested for the murders, which transpired in their Los Angeles residence on December 14, 2025. Nick’s background reveals a troubling history of substance abuse and mental health issues. Reports from local media indicate that he was receiving treatment for schizophrenia at the time of the incident.

Legal analysts suggest that Nick Reiner may pursue an insanity defense due to his mental health struggles. However, former California prosecutor Matt Murphy expressed skepticism about the viability of such a defense, emphasizing the challenges involved, particularly if Nick’s actions were influenced by drug use. In the weeks leading up to his parents’ deaths, Nick was reportedly prescribed medication for schizophrenia, a change in treatment noted by sources as having contributed to increasingly erratic and dangerous behavior.

The Reiners’ surviving children, Jake and Romy Reiner, have publicly expressed gratitude for the support they have received since the shocking loss of their parents. They have indicated that details regarding a memorial service will be announced at a later date. Friends and family gathered informally last week at the home of comedian Albert Brooks to remember the couple.

Rob and Michele Reiner were found dead shortly after attending a festive gathering at comedian Conan O’Brien’s home, where Nick was also present. Their untimely demise has drawn condolences from a variety of prominent political figures and celebrities, including former Presidents Joe Biden, Barack Obama, and Bill Clinton, as well as actors like Meg Ryan and musicians including Harry Connick Jr.

Nick Reiner faces two counts of first-degree murder, with special allegations indicating he employed a dangerous weapon in the slayings. If convicted, he could face severe penalties, including life imprisonment without the possibility of parole or potentially even the death penalty. As this case unfolds, it remains a somber reminder of the challenges posed by mental health issues and the devastating impact of violent crime within families.
