Benjamin Keough grandson of Elvis Presley, and son of Lisa Marie Presley — has died at age 27. Presley’s representative Roger Widynowski said in a statement Sunday to The Associated Press that Ms. Presley was “heartbroken” after learning about the death of her son. According to sources, Keough died from a self-inflicted gunshot wound Sunday in Calabasas, California. “She is completely heartbroken, inconsolable and beyond devastated but trying to stay strong for her 11-year-old twins and her oldest daughter Riley,” Widynowski said in the statement. “She adored that boy. He was the love of her life.” Presley is also mother to actress daughter Riley Keough, 31, and 11-year-old twin daughters, Harper and Finley, whom she shares with ex-husband Michael Lockwood.
