Hmm... I recall that the FBI was involved from the start, but how typical is this? In other words, when is the FBI joining the police in investigating a crime/problem?

For example, is it a matter of jurisdiction, such that the police is dealing with matters of local import, but the FBI is 'federal,' hence it intervenes when the issue transcends the bounds a given state or at least locality?

Or, is it a matter of expertise superiority, such that when a case seems more complex, or plain tough to crack, the police calls in the better equipped people?

Or a combination of these?

Or something else?
