Caller called 4 times in one afternoon.  Sounded like a fax machine beeping.

Told not to come  to court  that third party not served ' with full knowledge  knew have been served  with money lundering and financial fraud ' and unlawful detain personal property

It is probably the Fairfax County Police Department in Virginia. I missed a follow-up call for an incident, though the call back number left didn't match the number for the incoming call. I don't think it was a scam because I was expecting a call, and they did leave a message after several tries (not sure why they didn't leave a message to start with). The number seems to lead to several addresses, but that may be because there are several districts in the county. If you've reported an incident and are expecting a call-back, it's probably okay to answer. If you haven't had anything to do with them recently, let it go in case someone has spoofed the number, and etc.
