A death investigation is underway after the body of a Missouri doctor was found in northwest Arkansas more than a week after he was reported missing, police say.

Dr. John Forsyth, 49, was found dead Tuesday with what appeared to be a gunshot wound, the Benton County (Arkansas) Sheriff’s Office said in a statement.

His body was found by a kayaker in the water across from the area near Lost Bridge South Park, according to the statement. The park is roughly 26 miles from Mercy Hospital in Cassville, Missouri, where he worked as an emergency room physician.

He was last seen at the hospital on the morning of May 21 but did not show up for his afternoon shift, his brother Richard Forsyth told The Daily Beast. Cassville is a town of 3,100 in the Missouri Ozarks.

Richard Forsyth told The Associated Press that officials notified his family that his brother’s body had been found Tuesday night. He said his brother last spoke to his fiancée as he was leaving the hospital in the morning, The Daily Beast reported. Concern grew when he failed to return for his later shift, according to the outlet.

“He wouldn’t miss a shift even if his eyeballs were hanging out of their sockets,” Richard Forsyth told The Daily Beast last week. “It was an immediate red flag.”

John Forsyth’s vehicle, a black Infiniti, was later found at an aquatic park in Cassville. It was unlocked with items including his wallet, two phones, and a laptop inside.
