Nick Reiner, who is 32 years old, remains in custody following his arrest, with details of any forthcoming charges yet to be disclosed. As of Monday, online records confirmed his detention, with Police Chief Jim McDonnell revealing that his bail is set at a hefty $4 million (approximately AU$6 million).

Efforts to reach out to the Reiner family for comment have not been successful. Furthermore, it remains uncertain whether Nick Reiner has legal representation to speak on his behalf at this time.

Nick Reiner has been open about his personal battles with addiction. By the age of 18, he had already experienced multiple stints in rehabilitation centers, interspersed with periods of homelessness and recurring relapses.

His complex relationship with his father, Rob Reiner, and his own struggles with substance abuse were candidly portrayed in the 2016 film, Being Charlie, which is semi-autobiographical in nature.

The tragic deaths of Rob and Michele Singer Reiner, discovered on Sunday at their Los Angeles home, have sent shockwaves through the community. Investigators suspect they succumbed to stab wounds, according to a law enforcement source who spoke with The Associated Press.

The official, who was briefed on the investigation, confirmed that Nick Reiner was being held but could not publicly discuss the details and spoke to AP on condition of anonymity.

The Los Angeles Fire Department said it responded to a medical aid request shortly after 3.30pm and found a 78-year-old man and 68-year-old woman dead inside. Reiner turned 78 in March.

Detectives with the Robbery Homicide Division were investigating an “apparent homicide” at Reiner’s home, police Captain Mike Bland said Sunday.

Reiner was long one of the most prolific directors in Hollywood, and his work included some of the most memorable movies of the 1980s and ’90s, including This is Spinal Tap, A Few Good Men, When Harry Met Sally, and The Princess Bride.

His role as Michael “Meathead” Stivic in Norman Lear’s 1970s TV classic All in the Family, as a liberal foil to O’Connor’s Archie Bunker, catapulted him to fame and won him two Emmy Awards.

The son of comedy legend Carl Reiner, Rob Reiner was married to photographer Michele Singer Reiner since 1989. The two met while he was directing When Harry Met Sally and had three children together: Nick, Jake and Romy.

Relatives of Lear, the legendary producer who died in 2023, said their deaths left them bereft.

“Norman often referred to Rob as a son, and their close relationship was extraordinary, to us and the world,” said a Lear family statement. “Norman would have wanted to remind us that Rob and Michele spent every breath trying to make this country a better place, and they pursued that through their art, their activism, their philanthropy, and their love for family and friends.”

Los Angeles Mayor Karen Bass called it a devastating loss for the city.

“Rob Reiner’s contributions reverberate throughout American culture and society, and he has improved countless lives through his creative work and advocacy fighting for social and economic justice,” Bass said in a statement. “An acclaimed actor, director, producer, writer, and engaged political activist, he always used his gifts in service of others.”

Reiner was previously married to actor-director Penny Marshall from 1971 to 1981. He adopted her daughter, Tracy Reiner. Carl Reiner died in 2020 at age 98 and Marshall died in 2018.

Killings are rare in the Brentwood neighborhood. The scene is about a mile from the home where O.J. Simpson’s wife Nicole Brown Simpson and her friend Ron Goldman were killed in 1994.

Donald Trump’s bizarre social media post after Rob Reiner’s death

However, the tribute seemed to be a thinly veiled insult at the late director, with Trump lashing out at Reiner’s progressive political views and suggesting they were responsible for his death.

“Rob Reiner, a tortured and struggling, but once very talented movie director and comedy star, has passed away, together with his wife, Michele, reportedly due to the anger he caused others through his massive, unyielding, and incurable affliction with a mind crippling disease known as TRUMP DERANGEMENT SYNDROME,” the post read.

“He was known to have driven people CRAZY by his raging obsession of President Donald J. Trump, with his obvious paranoia reaching new heights as the Trump Administration surpassed all goals and expectations of greatness, and with the Golden Age of America upon us.”
