According to Captain James Smith of the Cassville Police Department, Forsyth's body was found in Benton County, Arkansas, and will be formally identified after an autopsy.

The Missouri ER doctor and father of eight who went missing last week, three days after proposing was found dead on Tuesday, according to his brother. Dr. John Forsyth, 49, was reported missing on May 21, after failing to show up for his 7 p.m. shift at Mercy Hospital in Cassville, an Ozarks hamlet of roughly 3,000 people.

On the day John vanished, he told his new fiancée that he would see her in "a little bit" but he never returned. His brother Richard Forsyth said authorities found his body in northwest Arkansas on Tuesday. Richard, however, claimed that there was foul play involved in John's mysterious disappearance and death.

A devastated Richard Forsyth said, "My brother is dead. He's been found. We're in shock. I suspect foul play." Richard said the family is expecting more details from a detective on Wednesday.

"He wouldn't miss a shift even if his eyeballs were hanging out of their sockets. He's punctual in the extreme," Richard told Fox News Digital. "It was an immediate red flag."

According to Captain James Smith of the Cassville Police Department, Forsyth's body was found in Benton County, Arkansas, and will be formally identified after an autopsy.

Richard said that John has been employed at the same hospital for 15 years and has never missed or been late for work.

According to Cassville Police Det. Stuart Lombard, the last person to hear from John Forsyth, who co-founded a cryptocurrency with his brother, may have been his fiancé.

They were texting around 7 am when John told his fiance that his shift was done and that he would see her "a little bit later." Then, according to Lombard, he abruptly stopped answering.

The doctor was seen on video surveillance making his way to his luxury RV, where he stayed in the hospital parking lot while working shifts.

Suspicious Death

John Forsyth's passport, wallet, two phones, RV, and car keys, according to Richard Forsyth, were all still inside the Infiniti when he disappeared. Richard referred to Forsyth's decision to leave the RV unlocked, along with his laptop and two other smartphones, as being "very uncharacteristic."

Lombard said that despite a canine and ground search of the 90-acre park surrounding the leisure center by police, the Missouri State Highway Patrol and other agencies had found nothing.
