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.

Legal sources have indicated that Nick is expected to plead not guilty by reason of insanity. His attorney, criminal defense lawyer Alan Jackson, has not yet publicly commented on the case.

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?

This dude might get a cushion sentencing due to an insanity plea. But if he tested positive for narcotics it may override that. It's not so easy to be granted with the insanity plea. Years of narcotics was his own personal choice and destructive behavior that probably contributed to his brain working poorly. Most if not all mental health medication warns you not to drink alcohol and or take d***s! Stay Sober with your antipsychotics!! This kid also had a support system and treatment beyond belief. He honestly didn't seem like he tried hard enough to want wellness. I have been on all that medication due to both Borderline Personality with bipolar 2 with psychotic features/ semi s****o. I'm bogged down with my brain. I got sober on my own and stayed sober. I even managed to get help with therapy without having insurance or a lot of money because I wanted it. To be well. I've seen people with dopamine imbalances be able to maintain themselves and even work and take care of kids. That was their success.

It would be extremely silly to let him out. If NOTHING else worked for him at all.. why set him free to cause more mayhem? If he does get the insanity plea it should save him from the death penalty. But, substance a***e was his own choice. His parents paid and didn't neglect his health. Rehabilitation and doctors played a role over and over and over again. Personality plays a huge role in behaviors and how much a person actually cares or wants something for themselves. People all over maintain their dopamine imbalances and succeed at it without k*****g their parents. Anytime "in between" new medications is brought up its mostly an excuse to get out of something. I've done that excuse several times in many situations. Jobs, jury duty, even being a witness in court. " OH! Well I wasn't of sound mind because I was off and on several different antipsychotics." 🙃
