The Vanishing at Smokestack Hollow

On October 8th, 2009, Bobby Jamison, his wife Sherilynn, and their six-year-old daughter Madyson, set off for a drive from their home in Eufaula, Oklahoma, to the nearby Sans Bois Mountains. They didn't return that day, or the next. A week later, their truck was found abandoned on a mountain road. Inside was their dog, malnourished but alive, the family's cell phones, wallets, and $32,000 in cash.

The ensuing eight-month search was the largest in Oklahoma history, but it yielded little evidence. Online, bloggers and web sleuths put forth dozens of theories, fueled by the Jamisons' strange, trancelike behavior on a CCTV video. Some claimed the family was abducted by white supremacists or a religious cult. In 2013, there was a tragic break in the case, when deer hunters stumbled upon the skeletal remains of two adults and a child in the Smokestack Hollow area of Panola Mountain. Forensic testing confirmed the Jamisons' identities.

But the mystery was only beginning. Had the Jamisons been planning to abandon their lives and raise Madyson alone in the wilderness—and if so, why? What happened to the briefcase and handgun that Sheryilynn was seen putting into the car? And why were no arrests ever made?
