Mathews calls in the repair shop as being on Barry 2 miles east of Highway 6. In the ensuing pursuit, the suspects are shown turning onto different roads several times. When they are apprehended, Sgt. Williams calls in the location as Barry 3 blocks east of Highway 6. They could not be on Barry since they had turned off of it some time ago. Additionally, the location where they were apprehended was near a "T" intersection where the road they were on ended requiring a left or right turn. As such, it did not go through to Highway 6, making a description of 3 blocks east impossible.
