The document analyzes the Luna case using the hypothesis generation method. It summarizes the FBI's investigation and analysis techniques used, and identifies gaps and areas left open to speculation. It then lists facts of the case and generates possibilities and probabilities to develop a hypothesis that the female FBI agent witness was involved in Luna's death to cover up their affair and her role in stealing money from an earlier case. The hypothesis is that she killed Luna to prevent him from revealing their relationship or her involvement in the theft when scheduled for a polygraph regarding the missing money.
