The family of Rob and Michele Reiner has come forward after the tragic news of the couple’s fatal stabbing in their Los Angeles residence.

“With deep sorrow, we share the heartbreaking news of Michele and Rob Reiner’s untimely deaths,” the family expressed in a statement to Variety late Sunday.

The statement continued, “We are devastated by this unexpected loss and kindly request privacy as we navigate this incredibly challenging period.”

According to sources, the bodies of Rob, 78, and Michele, 68, were discovered on Sunday afternoon by their 28-year-old daughter, Romy.

Sources have informed The Post that the couple’s 32-year-old son, Nick Reiner, who is a screenwriter, is considered a person of interest in the case. It is believed that a knife was used in the attack.

Nick is being questioned by police, according to People, though no arrests have been made yet.

According to TMZ, Rob and Michele had their throats slit by a family member during a heated argument inside their home.

Sources told the outlet that Romy told police the family member “should be a suspect” because they’re “dangerous.”

A neighbor told The Post that comedian Billy Crystal — a longtime friend of Rob’s — was spotted arriving at the home. Larry David was also seen at the residence following the murders and Crystal “looked like he was about to cry,” according to ABC 7.

Rob was famous for directing some of Hollywood’s most beloved films, including “When Harry Met Sally,” “The Princess Bride,” “This Is Spinal Tap,” “Misery” and “A Few Good Men.”

He first rose to fame for his role as Mike “Meathead” Stivic on the CBS sitcom “All in the Family,” which landed him two Emmy Awards.

Rob met Michele, a photographer, when he was filming “When Harry Met Sally.” They got married in 1989 and later welcomed three children: Jake in 1991, Nick in 1993, and Romy in 1997.

The filmmaker was also the adoptive father of actress Tracy Reiner, whom he shared with his first wife, director Penny Marshall, who died in 2018 at age 75.

Nick has spoken about his long battle with homelessness and drug addiction, which included repeated stints in rehab starting when he turned 15.

“I was homeless in Maine. I was homeless in New Jersey. I was homeless in Texas,” he told People in 2016. “I spent nights on the street. I spent weeks on the street. It was not fun.”

Nick’s story inspired the 2015 film “Being Charlie,” which he wrote and his father directed.

“It’s not my life,” Nick said about the film in 2016, “but went to a lot of these places, so I had a lot of these stories.”
