In March 2009, the FBI disclosed that Tom Kaye, a paleontologist from the Burke Museum of Natural History and Culture in Seattle, had assembled a team of "citizen sleuths", including scientific illustrator Carol Abraczinskas and metallurgist Alan Stone. The group, eventually known as the Cooper Research Team, reinvestigated important components of the case using GPS, satellite imagery, and other technologies unavailable in 1971. Although they gained little new information about the buried ransom money or Cooper's landing zone, they were able to find and analyze hundreds of minute particles on Cooper's tie using electron microscopy. "Lycopodium" spores (likely from a pharmaceutical product) were identified, as well as fragments of bismuth and aluminum.
