A Nebraska 18-year-old who celebrated his high school graduation with a trip to Arizona has been found dead in a desert bonfire pile — in what authorities described as a “malicious” death. Parker League’s body was discovered June 12 in the remote Bulldog Canyon, part of the Tonto National Forest, on the day he was supposed to fly back home after his trip to Tempe, KNXV reported. The Maricopa County Sheriff’s Office called League’s death “malicious.” The medical examiner is working to determine the cause of death. “He was found in the pile burning,” said police spokesman Sgt. Joaquin Enriquez.
