The cause of death for a 22-year-old man who died aboard a Southwest flight in August has been determined by the Los Angeles County Medical Examiner’s Office.
Rain McMillen Walmsley died from the “combined effects of 7-Hydroxymitragynine and Mitragynine,” according to the medical examiner. His manner of death has been listed as an accident. These compounds are found in kratom, a plant supplement that has been linked to an increasing number of overdoses.
Walmsley was traveling on a Southwest flight from Dallas to Los Angeles when he died mid-air. The incident highlights growing concerns surrounding the use and potential dangers of kratom.
