A 49-year-old Missouri doctor has gone missing after he failed to show up for work — and his vehicle was found abandoned at a park in the Ozarks.

Dr. John Forsyth, a physician at Mercy Hospital in Cassville, was last seen at about 7 a.m. Sunday — and was expected to work in the evening, police said.

His car was later located abandoned at the Cassville Aquatic Center, according to KOLR.

Police said the keys were still inside the vehicle, which was parked in a waste area, and the doors were unlocked, KY3 reported.

Forsyth, who stays at a trailer near the hospital, went there briefly after leaving the clinic Sunday morning, according to the news outlet.

Police said a K9 using scents from his clothes and car picked up a scent in a brush pile, but nothing came up, KY3 reported.

Authorities found two cell phones in his trailer and used a heat signature drone in the search.

The doc’s fiancée said it was odd for him to have vanished without a trace.

His sister, Tiffany Andelin, urged anyone with information to contact authorities and the family.

“If anyone knows anything, please contact us. I’m so worried, I’m a mess. That’s all I can say right now,” she wrote on Facebook.

“I think this is shareable now so if you know people in Missouri, please share. He’s been a doctor in the Aurora area for many years so I think he’ll be known by quite a few people,” Andelin wrote.

“Thank you, every one of you who has responded or shared this post. Knowing that people care and are watching out for him is a comfort, more than I can say,” she added.

The missing man was described as being 5 feet, 11 inches tall, weighing 180 pounds and wearing a black shirt with blue/gray pants when he was seen leaving the Cassville Mercy ER Clinic.
