It's probably a tossup. How much time can you usually put on a kitchen timer, an hour? Cut off the few minutes the timer would have had to be set early (since the timer presumably was not started when the bombs were placed, since that would be pretty conspicuous). That puts the guy at most an hours distance away, which granted, could be many miles. If the bombs were really placed in backpacks that were left sitting on the ground, I would further suspect that the bomber placed them much later an hour before. Wouldn't want someone to steal your bomb... Furthermore, maybe the sick fuck wanted to watch so he stuck around at a short distance instead of booking it. Who knows.
