Tragic news emerged as the search for a missing Missouri ER doctor, who had been missing since last week, took a devastating turn.

John Forsyth, a 49-year-old father of eight and a dedicated physician at Mercy Hospital in Cassville, has been found dead, according to his brother's statement Tuesday.

The unsettling disappearance of Dr. Forsyth began on May 21, shortly after he sent a text message to his new fiancée, assuring her that he would be with her "in a little bit." The subsequent days were filled with worry and concern as his whereabouts remained unknown.

Richard Forsyth, the brother of the deceased doctor, shared the heartbreaking news Tuesday that officials in northwest Arkansas had discovered John's lifeless body.

Expressing shock and disbelief, Richard alluded to the possibility of foul play and anticipated further details from the upcoming investigation.

Richard described his brother's work ethic and emphasized John's unwavering commitment to his profession, remarking, "He'd keep working even if his eyes fell out of their sockets." Such dedication made John's sudden absence more alarming, serving as an early warning sign for his concerned loved ones.

John Forsyth had dedicated 15 years of service to Mercy Hospital, exhibiting remarkable punctuality and an impeccable attendance record throughout his tenure, according to his brother.

Cassville Police Detective Stuart Lombard revealed to Fox News Digital that Dr. Forsyth's fiancée was the last person known to have been in contact with him before his disappearance.
