BRIDGEVILLE, Pennsylvania — Devlin Robinson wasn’t supposed to be at his Pennsylvania home that afternoon. Neither was his neighbor Mark Macala. And Adonis Whitmer, the FedEx driver who pulled in front of Macala’s driveway to deliver several packages? Well, he wasn’t supposed to be on that route that day either.

Had any of those three men done what they were supposed to do that day, June 13, it is likely this story would have a dramatically different ending.
