I got the same call as the one referenced above. It sounds as if the voice of the female is official but what she says sounds like it was pieced together for a scamers purpose because it doesn't really make sense and she doesn't even know my name. The reference number they left, "307-206-4539," is linked to other scams so don't sweat it.
Scam scam scam I have no idea why they are calling me saying that I'm being investigated but this is complete crap if you get this number reported to your local police department and hang up immediately
