The shocking double homicide of Hollywood legend Rob Reiner and his wife, Michele, has stunned the entertainment world, but for those close to the family, it marked the tragic end of a long-running nightmare driven by their son Nick Reiner’s mental illness and addiction.
Nick was thought to be using drugs again, and his parents feared for his mental state over the past few months, a family friend who has known Nick his entire life told The Post.
“Rob had been telling people that they’re scared for Nick and scared that his mental state was deteriorating. These poor people did everything to help this kid,” said the friend, who lives a few blocks from the Reiner home.

Rob and Nick got into some sort of fight at a holiday party hosted by Conan O’Brien Saturday night, the source confirmed to The Post.
“Nick was supposedly off drugs,” said the source, who then began hearing he was “not so much off them.”
