Nick Reiner, 32, charged with killing his parents in Brentwood, CA, citing schizophrenia and recent medication change.

Nick Reiner, 32, son of filmmaker Rob Reiner and Michele Singer Reiner, was charged with two counts of first-degree murder in the December 14, 2025, stabbing deaths of his parents at their Brentwood, California, home. Authorities say Reiner, who had a diagnosed history of schizophrenia and was undergoing psychiatric treatment, exhibited increasingly erratic behavior in the weeks prior, reportedly worsened by a recent change in medication. He was arrested hours after the killings, is being held without bail, and appeared in court wearing a suicide smock. His legal team may pursue a not guilty by reason of insanity plea. The case remains under investigation.
