Nick Reiner, accused of murdering his parents, filmmaker Rob Reiner and photographer Michele Singer Reiner, had been diagnosed with schizophrenia and was undergoing treatment at the time of the tragedy, which occurred last Sunday in a wealthy Los Angeles neighborhood. NBC reported on Friday. Three sources with direct knowledge of the case confirmed to the broadcaster that 32-year-old Nick Reiner was receiving treatment for schizophrenia at the time of his parents' murder. The filmmaker's son had been diagnosed with the mental illness years ago and was being treated with medication, sources detailed to NBC4's investigative unit, the network's Los Angeles affiliate. Additionally, they warned that the medication Nick Reiner was taking had been adjusted before the murders, but no specific date was given for the change or details of the prescription. For years, the young man struggled with drug and alcohol addiction, which inspired a film that his father co-wrote and directed. This Friday, it also became known that the judge overseeing the case signed a medical order that could be related to his mental health and the treatment he was receiving, according to NBC. Nick Reiner was arrested on Sunday night after one of his sisters found her parents' bodies dead in their home in the Brentwood neighborhood. Security cameras captured him moments before his arrest at a convenience store, where he bought a drink. Those close to him claim there was a family argument at a Christmas party at comedian Conan O'Brien's house. On Wednesday, Nick Reiner appeared at a hearing where he was charged with three counts related to his parents' deaths, which could carry the death penalty, said Los Angeles District Attorney Nathan Hochman. A hearing in the case is scheduled for January 7, but it could be postponed. The young man is being held without bail in a Los Angeles jail under special surveillance to prevent suicide. The investigation is focused on establishing the motives that may have led him to commit the alleged crime.
