New York, Los Angeles, and Washington, D.C. are the three largest FBI divisions. Like Dave, these two divisions are managed by higher-level personnel, and the corresponding field agents are more numerous. Jimmy was dispatched from headquarters to handle the yacht explosion case, so both he and Mark, who came to Los Angeles earlier, could receive support from the Los Angeles office, including access to information, vehicles, personnel, etc. However, if he wanted to handle the death cases occurring in Los Angeles, that would be overstepping his authority. Even if these two deaths are suspected to be non-natural, they should be handled by the LAPD or the personnel from the Los Angeles office.
Dave returned to his office, checked some information, and then glanced at the note on his desk before directly calling to book a ticket to Washington, D.C.
