This case raises serious concerns about due process, potential prosecutorial misconduct, and the responsibility of law enforcement agencies to disclose exculpatory evidence.
If New Hampshire State Police indeed withheld key information about Doe’s credibility from Massachusetts prosecutors and McCarthy’s defense team, it could have significantly impacted the trial’s outcome.
McCarthy’s legal team will likely argue that this newly revealed information warrants a new trial under the Brady v. Maryland precedent, which requires the prosecution to disclose any evidence that could be favorable to the defense.
The fact that Doe’s background investigation revealed inconsistencies and alleged dishonesty—yet was not shared with the court—could undermine the prosecution’s case.
Additionally, the claim that NHSP officials prevented their own investigator from alerting a police department about concerns regarding Doe’s integrity raises broader questions about internal law enforcement accountability.
It will be interesting to see how Judge Joshua Wall rules after reviewing the newly obtained documents. If McCarthy is granted a new trial, it could set a precedent for other cases where law enforcement agencies are accused of withholding crucial information.
