Nick Reiner, the son of famed director Rob Reiner and Michele Singer Reiner, has been arrested and is being held on suspicion of murder after his parents were discovered dead at their Los Angeles home on Sunday. The tragic scene was uncovered by his sister, Romy, who found their parents with multiple stab wounds.

Authorities confirmed that Nick Reiner, aged 32, is currently in custody without bail. The case is set to move to the Los Angeles County District Attorney's Office, which will decide on potential charges. Emergency services had been called to the residence, where Rob, 78, and Michele, 68, were pronounced dead shortly after their arrival.

Rob Reiner is widely known for his direction of iconic films such as When Harry Met Sally, This is Spinal Tap, and Stand By Me. His wife Michele was an accomplished actress and producer. As investigations unfold, Nick Reiner's past struggles with addiction and homelessness are coming to light, particularly as he co-created a film based on his experiences with his father in 2015.

Public reactions have been polarized. Following the news of the couple's deaths, President Donald Trump made remarks linking Reiner's political activism against him to the tragedy, which led to backlash from some quarters, including fellow Republicans advocating for empathy towards the grieving family. Friends of the Reiners have expressed their sorrow and criticized the politicization of such a painful event.

As the investigation progresses, many are left questioning the circumstances surrounding this family tragedy and the implications of mental health and addiction struggles within celebrity families.
