Both Rob and Michele Reiner were warned about letting their son Nick live at their home due to his medication being switched which could lead to more 'erratic' behavior, it has been claimed.
Nick Reiner, 32, appeared in Los Angeles Superior Court on February 23 where his lawyer entered a plea of not guilty to the murder of his parents two months after they were found stabbed to death in their $13.5 million Brentwood home on December 14.
It had been reported previously that the son of the Hollywood legend - whose siblings are no longer paying for his criminal defense- had suffered from schizophrenia and been open about his past with drug addiction.
Now, it has been alleged that Nick had fired his psychiatrist and changed medications shortly before Rob and Michele were brutally murdered.
'The medical staff warned Rob and Michele not to let Nick live at home until he got his medication straightened out,' a source told UsWeekly.
A second source told the publication that the parents were trying to help their son figure out their meds as 'they weren't working anymore.'
Medical Staff Allegedly Warned Reiners
The insider said that the family's medical staff had 'warned Rob and Michele not to allow Nick to stay at their home due to the meds being switched, and [said] that it could make him exhibit even more erratic behavior.'
Last week it was revealed that Nick's siblings are no longer paying for his criminal defense as he faces murder charges for allegedly killing his parents, which he pled not guilty to.
Hours after the killings, he was arrested and has been held without bail.
But as the case moves forward, with prosecutors confirming it is eligible for the death penalty, his legal representation now rests with a court-appointed public defender.
TMZ reported that sources connected to Romy and Jake Reiner said there is no plan to hire another private criminal defense attorney.
The outlet previously reported that prominent defense attorney Alan Jackson had been retained shortly after the murders but later withdrew from the case due to an undisclosed disagreement.
Public Defender Enters Not Guilty Plea for Nick Reiner
A public defender was appointed last month. At the time, it appeared to be a temporary measure. However, on Monday, Deputy Public Defender Kimberly Greene appeared in court and entered a not guilty plea on Nick's behalf.
One source told TMZ, 'Nick's defense is Nick's defense. They're not involved.'
The outlet reported that Jake and Romy have no plans to bring in private counsel and will no longer pay for his defense.
It remains unclear whether the siblings will weigh in on whether prosecutors should pursue capital punishment.
The 32-year-old looked gaunt and hollow-eyed as he sat hunched over in court in Los Angeles, California on Monday, wearing brown prison garb.
Nick was heard faintly whispering 'Yes' in court when asked if he understood the proceedings during his appearance, which marked the first time he's been seen in custody.
Nick's Third Court Room Appearance After Arrest
His head was shaved as he looked into the crowded courtroom, as if searching for someone he knows.
At one point, an unidentified elderly woman waved at him, and Nick mouthed 'hi' to her and the older man sitting next to her.
This was Nick's third court appearance after he was arrested following his parents' gruesome murders. It was the first time LA County Superior Court Judge Theresa McGonigle allowed him to be photographed in custody.
The death penalty is still on the table for Nick, LA County DA Nathan Hochman said.
Shortly after the three-minute hearing, Hochman addressed reporters outside the Downtown LA courtroom.
'The case is on track. We have provided the bulk of discovery to defense counsel and we are now waiting for the coroner's report. That will be provided to the District Attorney's Office and we will ensure that it will be provided to defense counsel.
'This case is a death penalty eligible case. Along those lines we take the process in which we determine whether or not the death penalty should be sought extremely seriously. That goes through a very rigorous process.
'We will be looking at all mitigating and aggravating circumstances, and we have invited defense counsel to present to us both in writing and in a pleading, any arguments they would like to make in consideration going forward or not going forward with the death penalty. So that is an ongoing process.'
He is due to appear in court again on April 29.
Nick has long dealt with mental health issues, as it was previously claimed that he had been placed in a mental health conservatorship five years before allegedly murdering his parents.
He also switched his schizophrenia medication about a month before his parents were found dead by his sister, Romy.
Conan O'Brien Breaks Silence
Nick's latest court appearance comes just days after comedian Conan O'Brien broke his silence on his parents' deaths.
Just hours before Rob and Michele were found, the filmmaker was seen clashing with Nick at O’Brien’s holiday party.
‘It’s just so awful,’ O’Brien, 62, said in an interview with The New Yorker on Friday.
‘I knew Rob and Michele, and then increasingly got closer and closer to them,’ he said, adding that he and his wife, Liza Powel O’Brien, ‘were seeing them a lot.’
‘They were just such lovely people. And to have that experience of saying goodnight to somebody and having them leave and then find out the next day that they’re gone. I think I was in shock for quite a while afterward. I mean, there’s no other word for it.
‘And I think about how Rob felt about things that are happening in the country, how involved he was, how much he put himself out there -- and to have that voice go quiet in an instant is still hard for me to comprehend,’ O’Brien added.
It was reported that all three Reiners attended O’Brien’s December 13 holiday party, where the filmmaker and his son were involved in a ‘very loud argument.’
It was also recently revealed that Nick has been acting ‘almost childlike’ in jail and that he is ‘not competent to stand trial right now.’
