The day after celebrated Hollywood director Rob Reiner and his wife Michelle were found dead, police took their 32-year-old son Nick into custody.
Suspected of murder and remains in custody until further notice, although it was previously announced that his bail was set at four million dollars.
Prosecutors now need to decide whether to press charges, police there said.
The bodies were found by their daughter Roma in the elite Brentwood neighborhood of Los Angeles, home to many celebrities, on the west coast of Los Angeles, several sources confirmed to CBS News, the BBC's American partner.
The Reiners suffered multiple stab wounds, the same media outlet reported, but the cause of death has not been officially announced.
Reiner directed many film hits, such as When Harry Met Sally (When Harry Met Sally), Misery (Miseri), A Few Good Men (A few good people) and TThe Princess Bride (Princess Bride).
He also directed the semi-autobiographical film Being Charlie (Being Charlie) from 2015, co-written by NIk, Rainer's son.
The film deals with the painful relationship between a young man in the grip of addiction and his father.
Nick Reiner previously said in an interview with People magazine (People) spoke about his struggle against dependence on others.

When was Nick arrested?
Nick Reiner is in custody and "has been charged with murder," said Los Angeles Police Department Chief Jim McDonnell.
After an initial investigation into the murder, it was “further discovered” that Nick Rayner was “responsible for their deaths,” police said on December 15.
Theories about a potential motive quickly circulated on social media.
US President Donald Trump linked the death of the director, an outspoken supporter of the Democratic Party, to Trump syndrome, which was also condemned by Republicans.
The president coined the phrase to describe his loudest and most persistent critics.
The motive for the murder has not yet been revealed.
Rainer spoke about his son Nick's problems
Being Charlie, a semi-autobiographical film by Nick Reiner, was released in 2015.
The Rainer family has previously spoken openly about Nick's long-standing struggle with substance abuse and addiction to hard drugs.
A father and son teamed up to write and direct a film about a drug-addicted teenager and his difficult journey to recovery.
The director and his wife felt desperate during their son's problems, but they didn't always listen to him when he told them the rehabilitation program wasn't working.
They trusted the experts who treated their son more.
Nick spent years in rehab centers and was homeless as a teenager.
"We were greatly influenced by these people."
"They would tell us he was lying and trying to manipulate us, and we believed them," Michelle Reiner told the Los Angeles Times in 2015.
"We listened to them instead of listening to our son," Rob added.
The film seemed to have a healing effect on the family.
When they started filming it, the relationship between son and father "became much closer."
Nick later told Variety that their relationship progressed during filming.
Although he loved working with his father on film, he wanted to be independent and complete his own projects.
Rainer had four children.
Rob Reiner was previously married to the late film director Penny Marshall and adopted her daughter, Tracy Reiner (61).
He met Michelle Singer during the filming of the film "When Harry Met Sally", and a few years later they had their first son - Jake.
In an interview with the BBC in 1998, shortly before the birth of his daughter, Romi, he reflected on parenthood.
His approach to raising children is changing, and his experience with his sons - Jake was six and Nick was four - played a big role in "learning how to be a parent."
That same year, Reiner helped pass an initiative to use cigarette tax revenue for a prenatal and early childhood program called California First Five.
"I hope that by investing in early childhood, I'm actually helping to improve the structure of society and that we'll reduce crime, teenage pregnancy, drug abuse and child abuse," said Reiner.
