Pickford’s dossier of evidence includes a letter dated 14 March 2000 from Leakey to George Abungu, the current director-gener- al of the National Museums3. In this letter, Leakey notes that Pickford is collecting fos- sils and suggests “that you urgently get assis- tance from the Director of CID and that you send an officer plus someone from [the National Museums] to intercept Pickford. His possessions should be thoroughly searched and any fossils should be confiscat- ed … A search should also be made of his premises in Nairobi.”
