Rigid Information Policy

A little under half way through his book, Shadow of Death, Philip Ginsburg writes about the newly formed task force investigating what became popularly known as the Connecticut Valley Serial Killer case.

Ginsburg cites the common practice of law enforcement, when working a multi-jurisdictional case, to limit public statements to one outlet:

The members of the task force were required to clear all public statements with the [New Hampshire] Attorney General’s office. Word of any developments, progress or achievement or simply effort, would come from Concord.

...there were reasonable goals behind the rigid information policy. It was intended to avoid prejudicing any future prosecution, to keep information from potential suspects...

Is this the reason the Amherst Police Department, as of this writing (09 March 2018), does not even acknowledge whether the Vasi hit-and-run case is either open or closed? Because the Vasi case may be related to the disappearance of Maura Murray? And therefore Amherst PD says little or nothing about it in deference to New Hampshire AG's office?

How convenient.
