In a major development in the case surrounding the deaths of actor-filmmaker Rob Reiner and his wife, Michele Singer Reiner, their son Nick Reiner has been charged with their murder. Los Angeles County prosecutors confirmed that Nick has been charged with two counts of first-degree murder. District Attorney Nathan Hochman announced this at a news conference alongside Los Angeles Police Department Chief Jim McDonnell. Prosecutors have also indicated that they plan to add a special allegation that a dangerous weapon, a knife, was used in the killings. McDonnell said, "This case is heartbreaking and deeply personal, not only for the Reiner family and their loved ones but for our entire city. We will continue to support the Reiner family and ensure that every step forward is taken with care, dignity and resolve." The charges come days after the couple were found dead with stab wounds at their home in the Brentwood neighbourhood of LA. Nick was arrested hours later on suspicion of the killings and has remained in custody since. District Attorney Hochman's office has yet to decide whether to seek the death penalty in this case. Nick was scheduled to appear in court on Thursday, but his attorney, Alan Jackson, said that he was not brought to the courthouse for medical reasons. He is now expected to make his court appearance on Wednesday. Jackson is a high-profile defence lawyer who has previously represented several prominent clients, including Harvey Weinstein. Police have not yet disclosed a motive behind the alleged double murder. Robert Reiner was an acclaimed actor and filmmaker, best known for directing films such as This Is Spinal Tap, The Sure Thing, The Princess Bride, When Harry Met Sally, Misery and A Few Good Men, among others. He received multiple honours, including two Primetime Emmy Awards for All in the Family, a Hugo Award, and nominations for an Academy Award, a BAFTA, and Golden Globe Awards. He was also honoured with a star on the Hollywood Walk of Fame in 1999 and received the Chaplin Award in 2014. Michele Singer Reiner was a photographer, film producer, and LGBTQ+ activist. The couple had been married for over three decades. Just months ago, Nick was photographed with his parents and siblings at the premiere of Spinal Tap: The End Continues. Rob and Nick had previously collaborated on the 2016 film Being Charlie, which explored the life of a troubled son of a famous father. It drew inspiration from personal experiences but was not a biography. Earlier, Nick had also spoken about his struggles with addiction and visiting treatment facilities often.
