The scene was catastrophic. The circumstances were tragic. But most of all, they were puzzling. Why would a 26-year-old man decide to detonate a car bomb to kill himself, a male passenger and his 2-year-old child? One year after the car explosion that rocked center city Allentown on a Saturday night in September, a team of Morning Call reporters spoke to the families of the victims -- Jacob and J.J. Schmoyer, and David Hallman -- and to federal agents. We know much more about the events leading up to Schmoyer's final act. Guests include Morning Call reporters Laurie Mason Schroeder and Manny Gamiz. The Morning Call Podcast is a production of The Morning Call in Allentown, Pennsylvania. Kayla Dwyer is the host and producer.
