Kaye and his team have been working on the case since 2009 . Various hypothesis have been put forward about Cooper ’s identity , including onesurprisingly go argumentthat he ( or she ) was a adult female in disguise . Kaye is inviting anyone conversant with Boeing in that sentence menstruum , or familiar with the materials found on the tie , tocome forwardwith any information that could further aid in the famed hijacker ’s designation .
