Rob Reiner and his wife, Michele Singer Reiner, were killed by their son, Nick, multiple sources confirm to PEOPLE.

On Sunday, Dec. 14, at about 3:30 p.m., the Los Angeles Fire Department (LAFD) was called to a home to provide medical aid, the LAFD told PEOPLE. Upon arrival, they found a man, 78, and a woman, 68, dead. Sources confirm the victims were Rob and Michele.

Rob is a director, producer and actor whose career includes some of Hollywood’s most beloved films — from his 1984 directorial debut, This Is Spinal Tap, to Stand by Me (1986), The Princess Bride (1987), When Harry Met Sally… (1989), Misery (1990) and A Few Good Men (1992).

He first became famous for his role as Mike on the Norman Lear TV sitcom All in the Family.

Rob was born in the Bronx, N.Y., in 1947. His father was legendary comedian Carl Reiner and his mother was actress and singer Estelle Lebost. 

Rob and Michele met when Rob directed When Harry Met Sally, and the couple married in 1989 before having three children.

Previously, Rob was married to the late Penny Marshall, who died in 2018 at age 75 of complications from diabetes.

In a 2016 interview with PEOPLE, Nick spoke about his years-long struggle with drug addiction, which began in his early teens and eventually left him living on the streets. He said he cycled in and out of rehab beginning around age 15, but as his addiction escalated, he drifted farther from home and spent significant stretches homeless in multiple states.

Nick told PEOPLE that the chaotic period of addiction — including nights and sometimes weeks sleeping outside — later became the basis for the semi-autobiographical film Being Charlie, which he co-wrote. 

“Now, I’ve been home for a really long time, and I’ve sort of gotten acclimated back to being in L.A. and being around my family,” Nick told PEOPLE at the time.
