Reiner was discovered on Sunday alongside his wife, Michele Singer Reiner, and both appeared to have died from stab wounds, NBC News reported, citing a source close to the family. Police said earlier on Sunday they had found two people dead at Reiner’s house in the Brentwood neighbourhood of Los Angeles, without disclosing their identities.
The Los Angeles Police Department on Sunday told reporters it was treating the case as a “death investigation,” and wasn’t seeking a suspect as the investigation continues. No one has been detained in connection with the case, deputy chief Alan Hamilton said. The Associated Press reported that a family member was being questioned by investigators, citing a law enforcement official.
“We’re going to try to speak to every family member that we can to get to the facts of this investigation,” Hamilton said.
The son of legendary comedian and writer Carl Reiner, one of the pioneers of TV comedy in the 1950s, Reiner followed in his father’s footsteps, winning bit parts in TV shows in the 1960s. His breakout role came playing Archie Bunker’s liberal son-in-law Michael “Meathead” Stivic in the long-running comedy All in the Family.
Reiner branched out into film directing, helming classics such as The Princess Bride, an adventure fantasy, and Stand by Me, a coming-of-age film based on a Stephen King story.
Reiner co-founded Castle Rock Entertainment, which would go on to produce dozens of films including When Harry Met Sally and A Few Good Men.
Reiner continued acting. His most recent film release was Spinal Tap II: The End Continues, a sequel to his 1984 mockumentary about a washed-up rock band.
He was also a well-known activist who contributed to liberal and Democratic causes.
