Where would I put in a formal concern/complaint about a doctor wife and cop husband doing shady stuff?

I know there's the state medical board and then there's some way to do a complaint against police but without getting into details this cop husband and doctor wife couple, have done some weird things over the years and I have noticed a pattern of harassment and shady things that is deeply concerning and I want it to be brought to the right people's attention but not sure if there's anywhere I can really talk to/write to that would investigate this claim as a couple rather than the individuals if that makes any sense.
