Michael Proctor, the former lead investigator in the Karen Read case, was heckled outside the courthouse in Dedham Tuesday.

The head of the Massachusetts State Police says firing Michael Proctor was a “righteous decision” — and that he doesn’t expect the former trooper’s appeal to the Civil Service Commission to succeed. “I’m confident that the civil service process will work itself out and at this point I have no reason to believe that they will see things any differently than we saw them,

King is one of at least three defendants seeking information about Proctor from the federal materials, which are under a secrecy order.
