Similarly to another commenter, I received a message that I am to be served legal documents tomorrow (for what I have no idea); also stated that they were calling from an unidentified “county process server”, and provided a number for Rose or Rosin (not clear which) and Associates, a business I have not been able to find online.

Did not leave a name just the phone number claimed to be from unnamed county process service division that had legal paper to be servered to a man I know to be dead. Did have a case number and named Rosin and Associates as point of call back at the number.
