We are still reeling days after the murders of Rob Reiner and his wife Michele Singer Reiner - allegedly at the hands of their own son Nick Reiner, according to cops in Los Angeles. And now one of Rob's most famous collaborators, Corey Feldman, is speaking out about the moment the news broke and the chilling instinct he says hit him immediately. Feldman, who starred in Stand By Me under Reiner's direction, appeared on The Rob Reiner Story: A Hollywood Tragedy, which was an ABC News special airing this week as a somber retrospective meant to honor Rob's extraordinary legacy.
