1.) Who originally steals the fetish from the museum? Is it Balthazar or Tortilla?
Balthazar, who was subsequently killed by Tortilla and made to look like a suicide.
2.) How did the dimond get into the fetish?
It was, I suppose, 'built in' by the original creators of the fetish, the Arumbaya Indians.
3.) How did Alonzo and Rodrigo know of the dimond?
Rodrigo Tortilla must have heard it from Lopez, and Alonzo from Tortilla. The actual relationship between Tortilla and Perez+Bada isn't really explained, which does make the history a bit of a guessing game.
