The death of a highly regarded Missouri emergency room doctor whose body was found 11 months ago in a northwest Arkansas lake has been ruled a suicide, Arkansas authorities said Thursday, in a case that fueled social media speculation about whether his disappearance had been tied to his cryptocurrency dealings. Dr. John Forsyth, 49, was last seen nearly a year ago near the RV that he parked at the Cassville, Missouri, hospital where he worked. The father of eight who was engaged to be married didn't show up for his shift at Mercy Hospital on May 21, 2023, prompting a search.
