A son of film director Rob Reiner and Michele Singer Reiner has been arrested and booked on suspicion of murder after the couple were found dead in their Los Angeles home.

The Los Angeles Police Department said on Monday that Nick Reiner, 32, had been arrested with no bail. The deceased couple's 28-year-old daughter, Romy, found her parents in their home with multiple stab wounds on Sunday, as reported by CBS News.

Emergency services were alerted around 3:38 PM local time, where the two victims, identified as Rob, 78, and Michele, 68, were pronounced dead at the scene. Following the incident, a security guard stood outside the family's Brentwood home as media attention surged.

Nick Reiner was apprehended hours later, around 9:15 PM. The police have yet to reveal a motive for the alleged crime, and the investigation remains active.

Known for directing iconic films like When Harry Met Sally and This Is Spinal Tap, Rob Reiner's legacy is marked by his contributions to cinema and political activism.

Adding another layer to this tragic narrative, Nick Reiner has expressed his past battles with addiction and homelessness, which he depicted in the semi-autobiographical film Being Charlie in 2015.
