In 1936, Oinkster and Dominic approached Indiana Jones and his "Archaeology 223" expedition outside the Hopi cave, and claimed to be with the Bureau of Indian Affairs, and tried to persuade the expedition to not enter the caves. However, Jones felt they were suspicious, and asked for identification. Without real IDs, the two thugs used their rifles to enforce their way. Jones suspected that they might be thieves, but later discovered a plot to turn the Hopi cave into a criminal hideout.
