Nick Reiner Pleads Not Guilty in the Killing of His Parents Rob and Michele Reiner

In a downtown Los Angeles courtroom on Monday, nick reiner pleaded not guilty to the alleged murders of his parents, Rob Reiner and Michele Reiner, a development that crystallizes the next legal and investigative steps in a case tied to questions of mental health, substance abuse and discovery volume.

Nick Reiner: Charges, arraignment and what happened in court

The 32-year-old is facing two counts of first-degree murder with the special circumstance of multiple murders. He is accused of killing his parents in their Brentwood home in December. On Monday he appeared on camera for the first time since his arrest in December, in a hearing that lasted less than five minutes.

During the brief appearance he wore prison-issued brown pants and a shirt. He was told he has the right to a quick preliminary hearing; when the judge asked if he agreed to waive that right, he responded yes. For the rest of the hearing he either looked down or stared at the judge. His next court date was set for April 29, and he remains in jail with no bail.

Courtroom history: prior appearances and how this one differed

• nick reiner made a brief first court appearance on Dec. 17, during which he waived the right to a speedy arraignment.
• In an earlier appearance he was behind a wall and did not show his face; for Monday's hearing the judge allowed cameras, permitting his first on-camera appearance since the arrest.

Defense counsel changes and public statements

Nick Reiner's arraignment was delayed after his defense attorney, Alan Jackson, withdrew from the case during his court appearance last month. Alan Jackson, who previously helped defend Karen Read in Massachusetts, said he had to withdraw because of "circumstances beyond our control, but more importantly, circumstances beyond Nick's control. " Jackson added, "Pursuant to the law in California, Nick Reiner is not guilty of murder, " and said, "We wish him the very best moving forward. "

After Jackson's withdrawal, nick reiner was assigned a public defender. A Reiner family spokesperson said at the time that the family "have the utmost trust in the legal process and will not comment further on matters related to the legal proceedings. "

Prosecutor's note on timing: discovery, coroner's report and experts

Los Angeles County District Attorney Nathan Hochman noted that the preliminary hearing scheduled for April 29 will likely be delayed because of the volume of discovery that must be reviewed by the defense, the fact that the coroner's report is still pending, and the possibility that defense counsel will seek additional expert testimony, all of which will require additional time.

Mental health, substance abuse and investigative work underway

Recent coverage indicates law enforcement and defense attorneys have been working to piece together nick reiner's psychiatric and substance abuse history. He has a documented history of addiction and substance abuse treatment, and friends have told investigators that his mental health had been deteriorating prior to the fatal stabbings.

Legal expert Joshua Ritter said that even if the defense does not pursue a full-fledged not guilty by reason of insanity plea, it is likely to try to bring in mitigating factors related to mental health. The question of what defense strategy will be deployed now sits at the center of pretrial planning as discovery and expert reviews continue.

What comes next in the case timeline

• Short-term: The next scheduled court date is April 29, though the preliminary hearing will likely be delayed for the reasons the district attorney outlined.
• Ongoing work: Defense teams and investigators are assembling psychiatric and substance-abuse records and awaiting the coroner's report; potential expert testimony may be sought.

This case remains active and developing; details about evidence and formal defense strategy are unfolding as discovery proceeds and the coroner's report is completed.
