Season two[]

Henry Thornwald revealed

Col. Thornwald is revealed as the culprit.

Col. Thornwald operated a one-man glider in the shape of a giant bird, the Wakumi and also posed as a Shaman to promote false legends about the bird; the reason was that he was trying to keep people away from a secret project that involved looking for aliens that were hiding in fallen meteors. Not even the government knew what he was doing. Thornwald was handed over to the local sheriff for kidnapping, two counts of unlawful imprisonment and for impersonating a shaman because, despite clearly outranking the sheriff, Thornwald was unauthorized to do so by the government.
