Nick Reiner’s schizophrenia medication reportedly led to erratic behavior, according to multiple sources.

A recent report has revealed that Nick Reiner, aged 32, has been diagnosed with schizophrenia and exhibited “erratic and dangerous” behavior following a medication adjustment in the weeks leading up to the tragic deaths of his parents, Rob and Michele Reiner, in their Brentwood home. The information came to light as Nick faces two counts of first-degree murder for the slayings that occurred on December 14.

Sources familiar with the situation stated that there was a concerning shift in Nick Reiner’s behavior as his doctors attempted to stabilize his mental health condition. Despite attending a high-cost rehabilitation facility in Los Angeles, where monthly fees reach ,000, his actions continued to alarm those close to him. The report further indicated that Nick’s long-standing battle with substance abuse, which began in his adolescence, has exacerbated his mental health decline.

The tragedy unfolded when Nick’s younger sister, Romy, 28, discovered the body of their 78-year-old father. Both of their parents, aged 68 and 70, were reported deceased due to multiple stab wounds. Following the incident, Nick Reiner was arrested later that same day and subsequently charged with murder on Tuesday. Should he be convicted, he could face life imprisonment without the possibility of parole or even the death penalty. His arraignment is scheduled for January 7.

Nick Reiner has been candid about his struggles with addiction and homelessness, which were documented in the semi-autobiographical film “Being Charlie,” co-written with his father and directed by Rob Reiner. In recent interviews, Rob Reiner spoke positively about Nick’s progress, claiming that he had not engaged in substance abuse for over six years and was in a “really good place.”

However, reports indicate that tensions escalated the night before the slayings, with accounts suggesting that the father and son were involved in a loud argument at a holiday party hosted by Conan O’Brien. This familial discord may have contributed to the tragic series of events that would follow.

As the investigation continues and the legal proceedings commence, Nick Reiner’s case sheds light on the complex interplay between mental health and substance abuse, raising important questions about access to mental health care and the challenges faced by individuals battling these issues. The case remains developing, and further updates are anticipated as authorities work to piece together the circumstances leading to this devastating incident.
