Nick Reiner placed on suicide watch after his arrest on suspicion of murder of parents Rob and Michele Reiner

Nick Reiner, who is accused of murdering his parents Rob and Michele Reiner, has been placed under suicide watch at the Los Angeles jail facility he’s being kept in after he was taken into custody on Monday.

Nick, 32, was arrested in connection with suspicion of murder and has no bail in connection with Sunday’s killing of the couple, officials said Monday.

Nick ‘is under supervision of the jail mental evaluation team’ at the Twin Towers Correctional Facility, a law enforcement insider confirmed to Daily Mail Monday.

Nick was being housed as of Monday evening in the area for inmates who have ‘suicidal ideation,’ the insider said.

Sources indicated to Daily Mail that investigators with the Los Angeles Police Department were still in the process of compiling their case, as Hollywood stars continued to grieve the show business stalwart.

The lifeless bodies of the couple had been discovered Sunday afternoon at their home in Brentwood, California, with detectives saying they believe they died as a result of lethal stab wounds.

On Tuesday, prosecutors will be given the case, after which they will declare how they are moving forward in the case against Nick.

Nick is expected to make an appearance before a judge in court this week, insiders told Daily Mail.

It was not immediately clear as of Monday evening if Nick Reiner had obtained a lawyer for representation, or been appointed one.

Law enforcement said they have yet to determine a motive in the double murder of the couple at their Brentwood California home.

Nick had past been candid about his issues with substance abuse, which led to homelessness and repeated rehab stints.

The father and son explored their complicated relationship in the 2016 film Being Charlie.

Rob Reiner told the AP in a 2016 interview that making the motion picture with Nick ‘forced us to understand ourselves better than we had.’

The filmmaker added, ‘I told Nick while we were making it, I said, “You know it doesn’t matter, whatever happens to this thing, we won already. This has already been good.” We’ve worked through a lot of stuff.’

Nick told People in 2016 interview that he had been to rehab on 17 occasions at that time, when he was 22-years-old.

Nick said that he had been confronted by family with the ultimatum of entering rehab or hitting the streets on multiple occasions – at times, choosing the latter.

‘If I wanted to do it my way and not go to the programs they were suggesting, then I had to be homeless,’ Nick said. ‘I spent nights on the street. I spent weeks on the street. It was not fun.’

Nick said that he had experienced homelessness in states including Texas, New Jersey and Maine.

A spokesperson for the Reiner family on Monday confirmed the family tragedy in a statement.

‘It is with profound sorrow that we announce the tragic passing of Michele and Rob Reiner,’ the spokesperson said. ‘We are heartbroken by this sudden loss, and we ask for privacy during this unbelievably difficult time.’
