Rob Reiner's son 'was disruptive at Conan O'Brien party' night before killings

Rob Reiner's son - who has been arrested on suspicion of murdering the filmmaker and his wife - was reportedly disruptive at a party hosted by comedian Conan O'Brien the night before the killings.

Nick Reiner joined his father and mother, Michele Singer Reiner, at the event on Saturday - and the couple were upset and embarrassed about his behaviour, Sky News's US partner NBC News cited a source as saying.

They also expressed concerns about his health.

The outlet cited another source saying Nick's behaviour had made other guests uncomfortable.

They said he interrupted a conversation filmmaker Bill Hader was having with two guests and - when informed it was a private conversation - stood still and stared before storming off.

Reiner and his wife apparently died of stab wounds, US media reported.

The Los Angeles Fire Department initially said a 78-year-old man and a 68-year-old woman were found dead inside a property in the Brentwood neighbourhood, without identifying the victims

The case against Nick Reiner, 32, will be presented to the Los Angeles County district attorney's office for consideration on Tuesday, according to the city's police department.

Police chief Jim McDonnell said the robbery and homicide division was handling the investigation.

"They worked throughout the night on this case and were able to take into custody Nick Reiner, a suspect in this case," he said, calling the deaths "a very tragic incident".

Trump branded 'sick' for response to killings

Meanwhile, Donald Trump has been branded "sick" after launching an extraordinary attack against the senior Reiner, describing him on Truth Social as "tortured and struggling, but once very talented".

Mr Trump said Reiner and his wife died "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, sometimes referred to as TDS".

"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, perhaps like never before. May Rob and Michele rest in peace," he wrote.

Celebrities and politicians have criticised Mr Trump for his comments, labelling them "disgusting" and "petty".

'Can you get any lower?'

"What a disgusting and vile statement," actor Patrick Schwarzenegger said on X, while Californian Democrat Zoe Lofgren condemned Mr Trump's comments as "a new low for this petty, hateful man".

Talk show host Whoopi Goldberg compared the president's comments to those he made after the assassination of right-wing activist Charlie Kirk, when Mr Trump hit out at critics.

"I don't understand the man in the White House. He spoke at length about Charlie Kirk and about caring, and then this is what he puts out. Have you no shame? No shame at all? Can you get any lower? I don't think so," she said.

'Sick'

"This is a sick man," California governor Gavin Newsom wrote on X.

Republican US House member Thomas Massie also addressed the comments, saying: "Regardless of how you felt about Rob Reiner, this is inappropriate and disrespectful discourse about a man who was just brutally murdered."

Who are the Reiners?

Nick Reiner has spoken publicly of his struggles with addiction. He cycled in and out of treatment facilities by the age of 18, with periods of homelessness and relapses in between.

He and his father explored their difficult relationship and his struggles with heroin addiction and homelessness in a 2016 film called Being Charlie, which they co-wrote.

Republican congresswoman Marjorie Taylor Greene referred to Nick Reiner's "drug addiction and other issues" in a statement on X.

"This is a family tragedy, not about politics or political enemies," Ms Taylor Greene said. "Many families deal with a family member with drug addiction and mental health issues. It's incredibly difficult and should be met with empathy especially when it ends in murder."

Rob Reiner was a celebrated director whose work included some of the most memorable movies of the 1980s and 1990s.

He directed classics such as This Is Spinal Tap, The Princess Bride, When Harry Met Sally, A Few Good Men and Stand By Me.

He also acted, starring in Sleepless In Seattle and The Wolf Of Wall Street among others. His most recent high-profile work was a recurring guest role in the hit show The Bear.

He met Michele Singer in 1989, while directing When Harry Met Sally. They have three children together.

Singer used to work as a photographer and took the photo of Donald Trump that appears on the cover of his book Trump: The Art Of The Deal.

'The stuff of Greek tragedy'

Former US president Barack Obama has led tributes. He wrote on X that "Michelle and I are heartbroken by the tragic passing of Rob Reiner and his beloved wife, Michele. Rob's achievements in film and television gave us some of our most cherished stories on screen".

Harry Shearer, who collaborated with Reiner on This Is Spinal Tap, said in a statement: "Rob was a friend and collaborator through much of my life. He was funny, he was smart, he was a mensch."

He said Reiner's wife was a "very good friend" to his own wife, Judith, adding: "This is unspeakable, the stuff of Greek tragedy."

Christopher Guest, who starred in Reiner's films This Is Spinal Tap and The Princess Bride, and his wife Jamie Lee Curtis said in a joint statement that they were "numb and sad and shocked about the violent, tragic deaths of our dear friends Rob and Michelle Singer Reiner".

Reiner was a champion of liberal causes and a political activist.

In the 2004 presidential election, he backed Democrat candidate John Kerry and featured in advertisements taking aim at incumbent president George W Bush.

Reiner also supported Democratic presidential hopefuls Al Gore and Hillary Clinton.

"This is a devastating loss for our city and our country. 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," Los Angeles mayor Karen Bass said.

California governor Mr Newsom paid tribute to Reiner's activism as he said he was "heartbroken" over the director's death.
