Rob Reiner’s son Nick arrested after the director and his wife were found dead at their home

LOS ANGELES (AP) — Rob Reiner’s younger son, Nick Reiner, was in custody Monday after being booked for what investigators believe was the fatal stabbing of the director-actor and his wife at their Los Angeles home a day earlier, authorities said.

It was not immediately clear what charges Nick Reiner, 32, would face. Online records show he remained in jail on Monday. Police Chief Jim McDonnell said he is being held on $4 million bail.

Representatives for Reiner’s family did not immediately respond to a request for comment and it wasn’t immediately clear if Nick Reiner had an attorney who could speak on his behalf.

Nick Reiner has spoken publicly of his struggles with addiction. By 18, he had cycled in and out of treatment facilities with bouts of homelessness and relapses in between. Rob and Nick Reiner explored their difficult relationship and Nick Reiner’s struggles with drugs in a semi-autobiographical 2016 film, ” Being Charlie.”

Rob and Michele Singer Reiner were found dead Sunday at their home in Los Angeles, and investigators believe they suffered stab wounds, a law enforcement official told 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 3:30 p.m. 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 Capt. 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.
