His Big Escape Plan
Walter saved up money and keenly noticed things around him while he planned his escape. He even noticed that the guard assigned for the Tuesday morning shift was lazier compared to the other guards. The inmates had to be patted down before they went inside the bus, however, this one guard just let them walk by.
The Bus Route
Walter Miller started to observe the common route of the bus and noted that there was one intersection where the bus would always make a stop. This specific stop was just right next to a wooded area.
