Police and sniffer dogs found human remains in a Missouri pond last Sunday, just a few days after they located a submerged car of a man who disappeared.

The remains are thought to be those of Donnie Erwin, who vanished 10 years ago on December 29, 2013, in Camden County in the Ozarks, the authorities announced on Monday. His last known whereabouts were in his silver 2002 Hyundai Elantra, which was retrieved from a pond in Southern Camden County following a tip from a YouTuber on December 16.

Last Saturday morning, sniffer dogs helped detectives find human remains in a pond, as per the Camden County Sheriff’s Office. On Christmas Eve, detectives and divers came back and found more human remains and a prosthetic hip, just like the one Erwin had.

The investigators feel pretty sure these remains and the hip are Erwin’s, but they’re waiting for a forensic expert to confirm it.

James Hinkle, a YouTuber, had been looking into Erwin’s disappearance on his own. Earlier this month, Hinkle talked to the person who owns the land with the pond after his drone saw a car underwater. The owner let Hinkle search the area on foot and by kayak. Hinkle even posted a video of his search on his YouTube channel, Echo Divers.

On December 16, Hinkle called the Camden County Sheriff’s Office to tell them what he found. The police managed to pull Erwin’s Hyundai out of the pond. They kept looking around the pond and nearby after getting the car out.

Erwin was 59 when he went missing, as mentioned in a missing person notice. He was 5 feet 8 inches tall, with brown hair and eyes, last seen in a blue coat, blue jeans, and gray loafers. Erwin was missing his left leg above the knee and had a noticeable scar from his elbow to his wrist on the same arm. The notice also mentioned he might have been using crutches.

Erwin’s family has been informed about the recent findings.

“All of us at the Camden County Sheriff’s Office who have investigated this case for ten years are elated at the recovery and overjoyed with the closure we know this brings to the family,” the department said in a rnews elease. “This development would not have been possible without the assistance of countless volunteers throughout the years. From the bottom of our hearts, we thank you all.”
