When a popular teacher was gunned down in her parents’ driveway on Mother’s Day 2018, a quiet Pennsylvania city was left scrambling for answers — who would want the young woman dead? As it turns out, there might be quite a few people.

One year after Rachael DelTondo was shot to death, there are plenty of theories, but no arrests, leaving some to wonder if the case will ever be solved.

The case shook Aliquippa and remains the ninth unsolved murder in a city with an underfunded and understaffed police department.

There are numerous potential leads for police to follow, including a young Aliquippa High School athlete named Sheldon Jeter and DelTondo’s ex-fiancé Frank Catroppa.
