According to two sources cited by TMZ, Nick Reiner had been under psychiatric care for mental illness in the weeks prior to the slaying of his parents.
His behavior had reportedly become “alarming,” and about a month before the fatal incident, doctors reportedly changed his medications. This resulted in Nick becoming “out of his head.”

The publication’s sources claimed that doctors were attempting to stabilize Nick with adjusted medications when the tragedy occurred.
Nick had also recently spent time at a Los Angeles rehab facility specializing in mental illness and substance a*use, with his schizophrenia reportedly worsening alongside his struggles with substance use, according to Page Six.

On Sunday afternoon, Rob Reiner, 78, and Michele Reiner, 70, were found lifeless in their Brentwood home by their daughter, Romy. Their throats had reportedly been slit, and they were hit with several stab wounds.
The LA County Medical Examiner confirmed the slayings were caused by “multiple sharp force injuries,” ruling the manner as homicide.

Nick was arrested later that night near Exposition Park in Downtown LA. He was initially booked at Parker Center Jail before being transferred to Twin Towers Correctional Facility, where he is being held without bail.
On Tuesday, prosecutors charged him with two counts of first-degree m*rder with a special circumstance of multiple m*rders. This carries a maximum sentence of life without parole, or possibly even the d*ath penalty.

During his first court appearance on Wednesday, Nick appeared stoic. He was wearing an anti-s*icide smock and he was shackled at both hands and feet.
He only spoke three words to confirm he wanted to waive his right to a fast arraignment: “Yes, your honor.”
Following the hearing, his lawyer told reporters that the case is “very, very complex and serious” and asked the public not to rush to judgment. Nick’s arraignment is scheduled for January 7.

Nick Reiner had a troubled life that was filled with substance a*use and bouts of homelessness

Nick lived in his parents’ guest house and had a history of violence, drug a**iction, and homelessness. He had reportedly been to rehab almost 20 times.
The night before the murders, he attended a Christmas party at Conan O’Brien’s home with his parents.
Sources stated that the couple was “reluctant to leave him home alone” due to his extreme and stressful behavior, which had grown increasingly concerning in recent weeks.

At the party, Nick allegedly behaved bizarrely and made guests uncomfortable, culminating in a heated argument with his parents.
Reports indicated that his parents left O’Brien’s party soon after their argument, though it was unclear if Nick left the event after the incident as well.
Nobody noticed before Nick had the thousand yard stare, a sign of dissociation from severe trauma? So he committed the double murder during a severe dissociation episode.https://t.co/oxw1HU9P3npic.twitter.com/Wmt4H00ArY

Substance abvse is often linked to schizophrenia and paranoia, that's not a big surprise. How much more are you going to wring out of this family's tragedy?
I’d be surprised if anyone was genuinely “startled” by the diagnosis; I live in a building where at minimum ten percent of the residents suffer from schizophrenia. We all pretty much figured it was schizophrenia upon hearing the news. I’ve read that insanity pleas are awfully hard to prove but still kinda hope his works anyway; that way, he’ll be put into a psychiatric facility where he could potentially get real help, unlike in the average jail.
Load More Replies...Sadly I went through the same thing with my son "God rest his soul". I would like to say that I have seen this play out similar in many circumstances. The m**h, and h****n cause szchitsophranic disorders. My son also said that he was told by the TV to k**l us. After a third stint in a psychology ward they sent him back home. In the end the d***s took him before anything could happen.
