"Grey's Anatomy" has just killed one of its major characters. On its latest episode, Andrew DeLuca, the surgical attending at Grey Sloan Memorial Hospital, the brother of Carina and the ex-boyfriend of leading role Meredith Grey, was killed on Thursday night's episode. He is a murder victim by the hand of a henchman in a trafficking ring. DeLuca, who Giacomo Gianniotti played, was stabbed by a human trafficker he and his sister had chased through Seattle. Doctors and nurses at Grey Sloan tried to save DeLuca, but unfortunately, he succumbed to his wounds. However, DeLuca's efforts didn't go in vain because, in the end, the traffickers were arrested.
