I should have seen it coming… I used this website — https://www.onlinedatareports.com/ — which began at www.police.us.org — and paid $1 for a background check of charges.

Three days later they tried to hit my card with a charge for $28.95, which fortunately Chase blocked.

My bad for not being more vigilant, may this post serve as a Google-able record for anyone else thinking about using this site.
