BK Doe
A hot, sunburned, naked man was discovered one morning in the summer of 2004 in Georgia by the dumpsters of a Burger King. He was believed to be dead since he was not breathing. His skin was raging and covered in fire ants. But he was still alive and appeared to be in reasonable physical health based on a checkup. He had a psychological issue.
He squinted his eyes shut and screamed when touched while in the hospital. He also couldn't remember his name. His nickname among nurses was BK Doe. In actuality, he didn't remember much of his past. He believed he had been in the woods for 17 years, but the only thing he was certain of was his birthdate, which was August 29, 1948, two days before he was discovered.
He changed his name to Benjaman many months later. He claimed that it seemed familiar, and until he learned who he was, Kyle would serve as his surname. However, this proved elusive. Nobody, including the police, FBI, US Marshals, Canadian authorities, or Interpol, was aware of his identity. Media, missing persons organizations, TV viewers, and internet users did not either.
He wasn't finally identified until more than ten years later through DNA matching. William Burgess Powell was his name. He'd simply never had many links, either social or familial, being from Lafayette, Indiana. He lost 20 years to a fugue condition for unknown reasons, however it is assumed that at this time he adopted the name Benjaman.
