We have now received 4,200 leads and detective teams continue working to follow up on all remaining workable tips. We remain hopeful that (and paragraph ends).
Imagine having to wade through that many tips. No wonder they have so many agencies involved (FBI, FDLE, U.S. Marshal Service, and
NCIS).
Is this the Naval Criminal Investigative Service and why are they involved? I didn't know they got involved in civilian investigations. YES
Google and your question shall be answered:
How does NCIS work with other law enforcement agencies?
NCIS frequently works with other federal, state and local law enforcement agencies, but specializes in crime within or directed against the Department of the Navy. Like many other agencies, NCIS is a primarily civilian agency that handles felony crime and domestic counterintelligence. However, given its diverse global mission, a significant portion of NCIS' investigations and operations occur in overseas venues, where the agency is engaged with foreign law enforcement and security services on a daily basis. NCIS also deals with many issues traditionally associated with other agencies, such as overseas counterintelligence, firearms and explosives, customs violations and immigration, fugitives, environmental crimes and protective services.
