New allegations have surfaced in the case of accused murderer Nick Reiner, the 32-year-old man accused of killing his parents inside their Brentwood home earlier this month, as a former rehab roommate claims Reiner harbored intense anger toward his family, particularly his father.
Reiner remains in custody at the Twin Towers Correctional Facility in Los Angeles without bail and has not yet entered a plea. His arraignment on two counts of murder is scheduled for February 23.
According to a report by the National Enquirer, sources close to the case say Reiner has been diagnosed with schizoaffective disorder and altered his prescribed medication roughly one month before the killings, allegedly due to concerns about weight gain. An unnamed source told the outlet that following the medication change, Reiner’s behavior deteriorated significantly.
It remains unclear whether Reiner was using drugs at the time of the alleged killings. He has previously entered rehab multiple times, with reports estimating at least 18 treatment attempts over the years. Law enforcement has not publicly confirmed whether substances were involved, and the alleged murder weapon has not been recovered.
A former roommate, Danny Svilar, who says he shared a room with Reiner as a teenager at a high-end Malibu rehabilitation facility, told Daily Mail that he was not surprised by the arrests.
“When I heard who the victims were, I immediately knew who the suspect would be,” Svilar said. He claimed Reiner frequently spoke about his parents with hostility, adding that the resentment was especially directed at his father.
Svilar alleged that Reiner openly expressed hatred toward his family during their time in rehab, though he emphasized that the comments were verbal and occurred years before the current charges. He also described Reiner as volatile, recalling an incident in which Reiner allegedly became physically aggressive toward him, requiring staff intervention.
Despite those claims, Svilar said Rob Reiner and his wife, Michele Reiner, were deeply involved in their son’s treatment, attending therapy sessions and family programs consistently. “They showed up for everything,” Svilar said. “They were trying to help him. They wanted him well.”
High-profile defense attorney Alan Jackson, who briefly represented Reiner before withdrawing earlier this month, has stated that under California law his former client “is not guilty of murder,” though he did not elaborate on the legal strategy.
Reiner has not commented publicly on the allegations. A spokesperson for the Reiner family said they have “full faith in the legal process” and declined to comment further.
Authorities have said both victims were awake and in separate rooms at the time of the fatal stabbings. The case continues to unfold amid intense public scrutiny due to the family’s prominence.
