PHILADELPHIA — A father who was preparing to walk his eldest daughter down the aisle. An aspiring actor who appeared as an extra in the “Creed” movie franchise. A teenager who tried to help a wounded friend. These are the stories of those killed in the all-too-familiar thrum of another mass shooting.

       Five people in a working-class neighborhood of Philadelphia were gunned down Monday in what became the deadliest among a rash of U.S. shootings that occurred around the July Fourth holiday. A gunman in a ski mask and body armor appeared to fire on people at random while they were on the street or in a car, authorities said.
