and IMPLIES he's a complete nutjob

(From a story on boston.com about a Bigfoot investigatory gathering in Michigan)

"......The late Grover Krantz, a Washington State University professor who specialized in cryptozoology, the study of creatures that have not been proven to exist, believed Bigfoot was a "gigantopithecus," a branch of primitive man believed to have existed 3 million years ago.

(This version CLARIFIES that Krantz is dead and that he was a professor, not a medical doctor.)"
