Nick Reiner made another court appearance on Wednesday to face charges related to the deaths of his parents, Rob Reiner and Michele Singer.

The 32-year-old Reiner appeared in front of Judge Sam Ohta at the LA Superior Court this week, displaying signs of anxiety and weight loss as he confronted the allegations against him.

He entered a plea of not guilty to six felony charges, which included two counts of first-degree murder, two counts of special circumstances for multiple murders, and two counts of using a deadly weapon, specifically a knife.

During the court session on Wednesday, Reiner consented to appearing in court again on September 15 for a preliminary hearing to determine a trial date based on the evidence presented by the prosecutors.

As reported by the Daily Mail, Reiner’s defense attorney, Kimberly Greene, stated that she is awaiting the discovery evidence from the prosecutors, taking over the case after Reiner’s previous lawyer, Alan Jackson, withdrew in January.

Deputy District Attorney Jonathan Chong revealed that they are still awaiting the autopsy reports on both victims, Rob Reiner and Michele Singer, who were fatally stabbed four months ago. The deaths of the couple have been officially classified as homicides due to multiple sharp force injuries.

It was noted that there was no mention of Reiner’s mental state during the January hearing, although there were claims that he was under psychiatric care for mental health issues around the time of the tragic incident.

In the weeks leading up to the killings, there were reports of concerning behavior by Nick Reiner. Allegedly, a heated argument ensued among the family members the night before the murders, following a disagreement about Nick’s conduct at a Christmas party hosted by Conan O’Brien.

Reiner had previously sought treatment at a prominent Los Angeles rehabilitation center focusing on mental health and substance abuse, a facility known for catering to affluent parents seeking help for their troubled children.

Rob Reiner, known for his acting and directing career, was recognized for his work in various films such as “The Wolf of Wall Street,” “The Princess Bride,” and “A Few Good Men.”
