Doctor Lakshmi Sammarco says a year old injury to his brain caused oxygen deprivation, but the cause of the injury is not known. His parents and President Trump have accused North Korea of torturing him. North Korea has denied it, He died in June 2017, less than a week after his return to Cincinnati.
