Two days after his tragic death, the Los Angeles County Coroner confirmed to HollywoodLife that Benjamin Keough died by suicide after suffering an “intraoral shotgun wound.” Benjamin, the 27-year-old son of Lisa Marie Presley, was found dead in the Los Angeles suburb of Calabasas on Sunday, July 12 with a gunshot wound to the “upper torso,” according to a police report. Benjamin, who bore an uncanny resemblance to grandfather Elvis Presley, was pronounced dead at the scene.
