For the first time in more than a quarter century, Westmoreland County will have a new top prosecutor. With 100% of the county’s 307 precincts reporting Wednesday morning, Republican Nicole Ziccarelli erased an early lead held by six-term Democratic incumbent John Peck and claimed the race for district attorney. Peck moved out to an early 6,000-vote lead by virtue of first 12,700 mail-in ballots reported by county election officials. Totals from votes cast in person on Election Day saw Ziccarelli steadily narrow the gap and with more than a third of the vote counted moved into the lead.
