Nick Reiner, 32, is charged with killing the 78-year-old actor and director Rob Reiner and his wife, Michele Singer Reiner, District Attorney Nathan Hochman announced at a news conference with LA Police Chief Jim McDonnell.

“Their loss is beyond tragic and we will commit ourselves to bringing their murderer to justice,” Hochman said.

Along with the two counts of first degree murder, prosecutors added special circumstances of multiple murders and a special allegation that the defendant used a dangerous weapon, a knife. The additions could mean a greater sentence.

Hochman said his office has not yet decided whether to seek the death penalty in the case.

“This case is heartbreaking and deeply personal, not only for the Reiner family and their loved ones but for our entire city,” McDonnell said. “We will continue to support the Reiner family and ensure that every step forward is taken with care, dignity and resolve.”

The announcement came two days after the couple was found dead from apparent stab wounds in their home in the upscale Brentwood neighborhood on the west side of Los Angeles. Nick Reiner did not resist when he was arrested hours later in the Exposition Park area near the University of Southern California, about 14 miles (22.5 kilometers) from the crime scene, police said.

Reiner had been expected to make an initial court appearance earlier Tuesday, but his attorney Alan Jackson said he was not brought from the jail to the courthouse for medical reasons and the appearance would not come before Wednesday.

An email sent to Nick Reiner’s attorney Alan Jackson seeking comment on the charges was not immediately answered.

Nick Reiner has not yet entered a plea. He was not brought to the courthouse from the jail Tuesday for unspecified health reasons, and his first appearance before a judge was postponed to Wednesday.

Rob Reiner was the Emmy-winning star of the sitcom “All in the Family” who went on to direct films including “When Harry Met Sally…” and “The Princess Bride.” He was an outspoken liberal activist for decades. Michele Singer Reiner was a photographer, movie producer and advocate for LGBTQ+ rights. They had been married for 36 years.

Representatives for the Reiner family did not respond to requests for comment. Police haven’t said anything about a motive for the killings.

Nick Reiner is being held in jail without bail. He was arrested several hours after his parents were found dead in their home in the upscale Brentwood neighborhood of Los Angeles on Sunday, police said.

Jackson, the defendant’s attorney, is a high-profile lawyer who represented Harvey Weinstein at his Los Angeles trial and Karen Read at her trial in Massachusetts. He was a central figure in the HBO documentary on the Read case.

Investigators believe Rob and Michele Singer Reiner died from stab wounds, a law enforcement official told The Associated Press. The official, who was briefed on the investigation, could not publicly discuss the details and spoke to the AP on condition of anonymity.

The killings were especially shocking given the warm comic legacy of the family. Rob Reiner was the son of comedy legend Carl Reiner, who died in 2020 at age 98.

Kathy Bates, who won an Oscar as the star of Rob Reiner’s 1990 film “Misery,” was among those paying tribute to the couple.

“I loved Rob,” Bates said in a statement. “He was brilliant and kind, a man who made films of every genre to challenge himself as an artist. He also fought courageously for his political beliefs. He changed the course of my life. Michele was a gifted photographer.”

Bill Clinton called the couple “good, generous people who made everyone who knew them better.”

“Hillary and I are heartbroken by the tragic deaths of our friends Rob and Michele Reiner,” he said in a statement. “They inspired and uplifted millions through their work in film and television.”

Three months ago, Nick Reiner was photographed with his parents and siblings at the premiere of his father’s film “Spinal Tap 2: The End Continues.”

He had spoken publicly of his struggles with addiction, cycling in and out of treatment facilities with bouts of homelessness in between through his teen years. Rob and Nick Reiner explored — and seemed to improve — their relationship through the making of the 2016 film, “Being Charlie.”

Nick Reiner co-wrote and Rob Reiner directed the film about the struggles of an addicted son and a famous father. It was not autobiographical but included several elements of their lives.

“It forced us to understand ourselves better than we had,” Rob Reiner told the AP in 2016. “I told Nick while we were making it, I said, ‘You know it doesn’t matter, whatever happens to this thing, we won already.’”

Rob Reiner was long one of the most prolific directors in Hollywood, and his work included some of the most memorable and endlessly watchable movies of the 1980s and ’90s, including “This is Spinal Tap” and “A Few Good Men.”

He met Michele Singer Reiner on the set of “When Harry Met Sally…,” and their meeting would inspire the film’s shift to a happy ending, with stars Billy Crystal — one of Reiner’s closest friends for decades — and Meg Ryan ending up together on New Year’s Eve.

The Reiners were outspoken advocates for liberal causes and major Democratic donors.

President Donald Trump on Monday blamed Rob Reiner’s outspoken opposition to the president for the actor-director’s killing, delivering the unsubstantiated claim in a social media post that seemed intent on decrying his opponents even in the face of a tragedy.
