SIOUX FALLS, S.D. (KELO) — In August of 2020, a car was discovered in a cornfield in Gregory County where the owner’s dog had also been found, but Ryan Pyle seemed to vanish without a trace. His remains were discovered months later. KELOLAND’s Angela Kennecke is investigating this mystery death along the Missouri River.

For two long years, his family has been searching for answers. And that search brings them back to South Dakota time and time again.

Brian and Nikki Pyle made their third trip from the state of Washington to South Dakota to try to figure out what happened to Brian’s son. The 37-year-old was just passing through South Dakota when he was reported missing in 2020. Months later his remains were found in a rural area near the Missouri River by Platte.

“I feel like he was kind of turning a corner, and he was coming home and I was going to work with him again and he got stopped short,” Brian Pyle said.

Authorities first believed Ryan Pyle was just another death in a rural area due to exposure, not all that uncommon in South Dakota. But there is evidence that is not the case and more questions than answers for Ryan’s family.

“And I want answers and I want to know what the authorities know. And I just want some transparency and I just want some answers, that’s all. It won’t bring him back. I think something really wrong happened here,” Brian said.

Coming up in Monday night’s KELOLAND News investigation into the “Mystery death along the Missouri,” we look at things that don’t add up in the case and new evidence that points to foul play.
