Rob Reiner's Son Nick's Shocking Charges Revealed After Troubled Drug Addict Arrested for Parents' Disturbing Murders

Nick Reiner has been charged with two counts of first-degree murder with the special circumstance allegation of multiple murders, Los Angeles County District Attorney Nathan Hochman announced at a press conference on Tuesday, December 16.

The troubled drug addict also faces a special allegation that he personally used a dangerous and deadly weapon, a knife, to kill his parents, Rob Reiner and Michele Singer Reiner.

"Prosecuting cases involving family violence are some of the most challenging and heart-wrenching we face because of the intimate and often brutal nature of the crimes," Hochman explained. "Rob Reiner was one of the greatest filmmakers of his generation. His murder and his wife of more than 35 years, Michele Singer Reiner’s murder, are shocking and tragic. We owe it to their memory to pursue justice and accountability for the lives that were taken."

The decision comes just two days after Rob and Michele were found dead with slit throats at their Los Angeles home on Sunday, December 14.

Nick is being held without bail at Los Angeles' Men's Central Jail, per his attorney Alan Jackson. Earlier on Tuesday, the 32-year-old did not show up to court because he had not yet been "medically cleared." His appearance before a judge will be determined on a "day-to-day" basis and may occur on Wednesday, December 17.

As OK! previously reported, Nick was accused of the murder after checking himself into The Pierside Santa Monica hotel around 4 a.m. on Sunday morning. His room was reportedly covered in blood, and the windows had bed sheets hanging over them. He was taken into custody on Sunday evening.

The young screenwriter allegedly got into a feud with his parents at Conan O’Brien’s Christmas party on Saturday night, leading to the tragic events one day later.

Rob and Michele's daughter Romy phoned the cops on Sunday after she found her dead parents. She called out Nick, rendering him a "dangerous" suspect.

Things have reportedly been tense between the father-son duo for years. According to podcast host David Manheim, Nick cut off their friendship after he requested that Rob appear as a guest on the show in 2018.

“I wish I hadn’t asked him to have Rob Reiner come on the show, or at least not when I did, because it pushed him away,” he explained.

Nick has been in and out of rehab 18 times, and David recalled him struggling to stay clean.

“I don’t remember that he was particularly interested in 12-step work,” David said. “I know he had been to treatment. I know he was involved in writing. I know he loved to play pick-up basketball in New York City. I think he was interested in spirituality.”

David also remembered Nick feeling the pressure of living up to his dad’s successes.

“In the little picture, when he was actually making things — when he wrote Being Charlie, or he had an idea — I think he was just another person with an idea,” David explained. “[But] I think big-picture, when you’re up against Rob Reiner and Carl Reiner, and you’re a struggling drug addict, the pressure is immense because how accomplished is anybody at age 24?”

Nick spoke of this pressure as well in a 2016 interview.

“I live under quite a shadow,” he said at the time. “It’s annoying questioning every friendship you’ve ever been in: ‘Is it me, or who had me?’”

The 32-year-old was homeless at one point and lived on the streets of Texas, Maine and New Jersey.

“It was alright. It was a change of scenery!” he joked. “I’m so grateful I’m still alive, and I can say I’m more than a spoiled rich kid."

In another interview from that same year, Rob disclosed what it was like helping his son cope with addiction.

"I was never angry," the late actor expressed. "I felt bad for him and I didn’t know what to do to help – and a lot of times parents don’t know what to do…you kind of throw yourself at the mercy of a lot of people who are supposed experts. They’ll all tell you these things, but they don’t take into account your child. And you should know your child better than they do anyway. That is something I learned as we went along."
