Filmmaker Rob Reiner and his wife, Michele Singer Reiner, were found dead with stab wounds Sunday afternoon in their home in Los Angeles. Their deaths are being investigated as a homicide, according to law enforcement. Reiner was a longtime actor and director and was known for his films “The Princess Bride,” “When Harry Met Sally” and “A Few Good Men.” He rose to fame as one of the stars of Norman Lear’s “All in the Family.” Reiner was also a prominent donor and supporter of Democratic candidates. Los Angeles Mayor Karen Bass said, “An acclaimed actor, director, producer, writer, and engaged political activist, [Rob] always used his gifts in service of others. He and Michele fought for early childhood development and marriage equality, working to overturn Proposition 8. They were true champions for LGBTQ+ rights.”
