Rob Reiner and his wife, Michele Singer, were found dead at their Brentwood home on Sunday, according to TMZ.

The LAPD confirmed that they had responded to the home at 3:40 p.m. and discovered two deceased victims. The LAPD described the deaths as “an apparent homicide,” but did not confirm the victims’ identities. ABC7 reported that the victims appeared to have been stabbed.

A Los Angeles Fire Department official stated that the deceased were a man and a woman, aged 78 and approximately 68 years old, matching Reiner and Singer’s ages. Detectives from the LAPD Robbery Homicide Division responded to the home to conduct the investigation.

Reiner is a major filmmaker who comes from a storied Hollywood family. His father is comedian and director Carl Reiner. Reiner’s films include such classics as “This Is Spinal Tap,” “The Princess Bride,” “Stand By Me,” “Misery,” “When Harry Met Sally…” and “The American President.” A prominent progressive voice in the Hollywood community, Reiner is active in several California ballot initiatives, as well as acts as a major fundraiser for the Democratic Party. He has been a major critic of President Donald Trump.

Before moving behind the camera, Reiner also starred as Michael “Meathead” Stivic, hippie son-in-law of Carroll O’Connor’s bigoted, blustering blue-collar worker Archie Bunker, during nine seasons of “All in the Family.” Reiner co-founded Castle Rock, the production company behind hits such as “In the Line of Fire” and “City Slickers,” the critically acclaimed drama “The Shawshank Redemption,” and “Seinfeld.”

Singer was at one time a photographer who shot Donald Trump’s photo for the cover of “The Art of the Deal.” The couple have three children — Jake, Nick and Romy. He is the adoptive father of actress Tracy Reiner, the daughter of his first wife, the late actress and director Penny Marshall.
