Most counties are audited by a state agency or an independent firm, and those reports are public record. We haven't yet obtained and machine-read one for Middlesex County — so this is a dead end in our sense of the word: not navigable here yet, never hidden. When a report is in hand it's quoted and cited on this page, with the regulatory-basis note up front so boilerplate isn't misread as scandal.
Know where Middlesex County's audit lives? Point us to it and it goes in the queue. Meanwhile, follow the money that is mapped on the money trail.
