Nick Reiner, accused of a double murder, finds himself isolated with grim thoughts inside a Los Angeles prison, a stark contrast to the affluent lifestyle he once enjoyed courtesy of his parents.

With no visitors apart from his public defender, Reiner’s high-profile case has led to his confinement in a solitary cell, away from the general inmate population.

The 32-year-old faces charges for allegedly murdering his father, filmmaker Rob Reiner, and his mother, Michele, by slashing their throats on December 14.

In court last week, Reiner appeared wearing a brown gown typical of inmates in ‘mental observation housing,’ indicating he is under frequent checks every 15 minutes due to a suicide risk, as he pleaded not guilty to the charges.

The Twin Towers facility, which houses male and female inmates separately, was criticized by senators in 2023 for its dire conditions, where inmates were reportedly found shackled to tables, sleeping on urine-soaked floors, and sitting in their own waste.

Reports from the US Justice Department also highlight a troubling history of sexual assaults within the facility, involving both inmates and the deputies assigned to guard them.

Former LA County Sheriff Alex Villanueva told the Daily Mail that Nick has most likely not been allowed to associate with any other inmates in the Twin Towers Correctional Facility downtown.

‘Any type of case like this, a high-profile case, causes the department to place the inmate in what’s called administrative segregation, designed to prevent the inmate from being hurt by other inmates,’ Villanueva said.

‘I saw some of his first court appearances, and he was wearing what we call a suicide gown,’ Villanueva said of Nick. ‘That’s one garment held together with Velcro that can’t be ripped apart to form ligatures.’

Former sheriff Villanueva was in charge of jails for the county between 2018 and 2022, overseeing an inmate population of around 21,000, the largest in the US. He also worked in jails during his police career.

The ‘gown’ precaution, the ex-sheriff said, was to prevent the inmate hanging himself using torn strips of fabric, like late pedophile financier Jeffrey Epstein did while awaiting trial in 2019.

Villanueva added that the outfit indicated Nick is in ‘mental observation housing,’ where the most unstable inmates get constant surveillance.

‘They get mandatory checks every 15 minutes at a minimum, 24/7,’ he said.

‘He’ll be in a cell on his own. They have day rooms, areas that are restricted to similar inmates. But some are classified as K10s, who they keep away from everybody.’

A ‘K10’ inmate is deemed too dangerous to associate even with the other segregated prisoners.

‘Some have to remain alone at all times because they’re a danger, not only to others, but to themselves too. They want to hurt themselves, or they want to hurt somebody else,’ the former sheriff said.

A source who has spent time in the same mental health unit says conditions there are ‘horrible’.

‘There are crazies everywhere,’ the source said.

‘It’s the kind of place you don’t want to spend two minutes in. It makes One Flew Over the Cuckoo’s Nest look like a day spa,’ the source added, referring to Ken Kesey’s famous 1962 novel about a brutal mental institution.

Instead of meals at restaurants such as Nobu in Malibu – the LA beach town where his family own a home – Reiner has had to quickly grow accustomed to ‘gross’ pasta and beans provided by the jail. 

‘The food is not that good, but that is the way jail food is – lots of mystery meat,’ the source told the Daily Mail. ‘It is tasteless, but at least there are no bugs in it.

‘And there is no metal silverware because it can be used as a weapon. So only plastic sporks – like a spoon and fork combo – are used.’

According to the source, the only people Reiner now sees are prison staffers.

‘He will see guards and the psychiatrists that talk to him, but when he does, he will be handcuffed and watched. He is high risk, so many precautions will be taken. He is restricted, there is zero freedom,’ the source said.

He is also being constantly monitored by doctors, according to the source.

‘You have to talk to psychiatrists a lot, you can’t get out of it. And often, the patients are on medications – they vary; some make you totally out of it,’ the source added.

‘I don’t know what Nick is on, but medications are a part of the stay. They can refuse them, but often they just don’t know what is going on so they take them.’

But the worst part of a stay in the unit is fellow inmates.

‘They constantly scream night and day – they don’t shut up. There is no mute button,’ said the former inmate. ‘They don’t know what they are saying or doing.

‘The noise really gets to you, it rocks your nervous system because it’s weird, like howling and all the profanity and sick sex talk. It’s not good.’

The temperature of the jail makes the situation worse, according to our source.

‘It’s really cold in there at all times, you are always cold, it’s not a good feeling, especially in the winter,’ he said. ‘It’s not like you can crank up the thermostat or ask for a down comforter or cashmere throw. And it’s dark – you don’t see much sunlight.’

Another law enforcement source close to the jail administration told the Daily Mail that Reiner was in a unit with intense, regular observation due to the violence of his alleged crime and history of poor mental health.

The source also said that he had received no family or friends at the jail, although his aunt Annie Reiner – Rob’s younger sister – did show up at court on Monday.

‘It appears only his attorney has visited at this time,’ the source told the Daily Mail.

The heavily monitored category Reiner is said to be in is very different to the average prisoner.

‘In general population, you live in a dorm setting. You have multiple people in one cell,’ said Villanueva.

Just three months before the tragedy the Reiner family – including Nick – were all smiles at the premiere of Spinal Tap 2: The End Continues in LA

‘You can do outdoor recreation activities or day room recreational activities surrounded by other inmates that have the same security classification, and you’re not segregated.’

Villanueva, who plans to run for reelection to his old post in November, said Reiner will have been given a ‘full medical screen’ including a mental health assessment when he was placed in the jail.

‘They have to figure out what medication he was taking and continue him taking that medication until doctors agree to change it,’ he said.

Reiner’s pills may become a pertinent issue in his case.

TMZ reported that Reiner switched to a new medication for his alleged schizoaffective disorder a month before the killings.

But Villanueva was skeptical, saying the report was the kind of information a defense attorney would want placed in the media to start building a public case for an insanity defense.

‘The lawyer is going to claim a change in medication,’ he said. ‘But in many cases we’ve seen on the streets, the person is under psychiatric care, and then they just stop taking psychiatric medications. Then they fall apart and they go back to whatever the behavior was that got them on the meds in the first place.’

The ex-sheriff predicted that Reiner ultimately changing his plea to ‘not guilty by reason of insanity’ would be ‘a likely course of action.’
