Man found naked behind Burger King with amnesia may have concealed mysterious past for decades

Eric and Shannon Evangelista's investigation follows Benjaman Kyle's trail from Indiana to Colorado​

In August 2004, a man was found unconscious behind a Georgia Burger King. Initial reports described him as naked and bloodied. When he woke up, he claimed he had no memory of who he was. Now, two filmmakers are attempting to uncover what happened during the decades when he was missing.

On May 25, Investigation Discovery (ID) premieres the four-part docuseries "The Many Lives of Benjaman Kyle," which follows Eric and Shannon Evangelista as they attempt to help the mysterious man, who claimed to suffer from a rare form of amnesia, piece together his lost identity. But after the man was identified in 2015 as William Burgess Powell, the investigation takes an unexpected turn.

It’s unclear whether Powell, who appears in the docuseries, disputes the filmmakers’ conclusions.

Powell hasn’t been arrested or charged with any crime. He also doesn’t appear to have any criminal record, People magazine reported. According to the docuseries, his whereabouts are currently unknown, and the filmmakers are encouraging anyone with leads to reach out to their Hot Snakes Media production company.

"We’ve never stopped, and we’re still investigating," Shannon told Fox News Digital. "I think the big question that’s still looming, the driving force for us, is where he was from 1983, when his Social Security earnings stopped, until 2004, when he was found at a Burger King. We’re hoping the public will help us answer that."

Hospital staff nicknamed Powell "B.K. Doe" for "Burger King Doe." He then began identifying himself as Benjaman Kyle. While he was diagnosed with retrograde amnesia, which causes someone to lose memories before an event such as a brain injury, trauma or illness, Shannon’s husband, Eric Evangelista, began to question his diagnosis.
