You could say it started with three small-town Minnesota boys riding their bikes to a convenience store on an October night in 1989. As they were returning home on a dark stretch of road, a man stepped out of the darkness holding a gun. He told them to lie face down on the ground and then directed two of them — Trevor Wetterling, age 10, and Aaron Larson, 11, to run into the woods and not look back or he’d shoot them. That was the last that they, or anyone, would see of 11-year-old Jacob Wetterling.
