Rob Reiner and his wife, Michele Singer Reiner, were found stabbed to death recently in their Brentwood home in Los Angeles, and Los Angeles Police Department investigators arrested their son, Nick Reiner, 32, on a murder charge and set bail at $4 million while forensic testing and interviews continue.Investigators said both victims suffered multiple stab wounds and described the deaths as an apparent homicide as detectives prepare pretrial filings and the Los Angeles County District Attorney's office reviews evidence and possible motives.Colleagues including James Woods publicly defended Reiner and recalled his mentorship and film legacy, while public reaction split after Donald Trump posted comments linking the deaths to what he called "Trump Derangement Syndrome," a post that drew criticism and renewed debate over political rhetoric.
