Whether the Commonwealth committed a constitutional violation under Brady v. Maryland by failing to disclose the Stoltzfus materials.
Holding
No. The materials were favorable impeachment evidence and were suppressed, but Strickler did not establish Brady materiality because he did not show a reasonable probability of a different result.
Reasoning
A true Brady violation has three elements: the evidence must be favorable to the accused because it is exculpatory or impeaching; the State must have suppressed it, deliberately or inadvertently; and prejudice must have followed. The prosecutor’s duty extends to favorable evidence known to police investigators, even if the prosecutor personally did not know of it.
The undisclosed Stoltzfus documents were plainly impeaching. They sharply contrasted with her confident trial account by showing uncertain, evolving, and police-assisted recollections. At least five documents were unquestionably not disclosed to the defense, so the first two Brady elements were satisfied.
But suppression alone does not establish a constitutional Brady violation. Evidence is material only when there is a reasonable probability that disclosure would have changed the outcome. The governing question is whether the suppressed evidence puts the whole case in such a different light that confidence in the verdict is undermined, not whether the remaining evidence would still have been legally sufficient to support conviction.
