While the Patch article and interview video is very interesting (it was originally posted here last night) the guy saw Gliniewicz's car and heard and saw nothing else.
What I was prompted to do this morning was to seek the location of the business in relation to the old cement plant. I urge anyone who is curious enough, to do the same thing. The address of the business is 105 Precision Drive. Once you get there using Google, use streetview and follow Precision Drive back to Honing Road. That is where the paved portion of Honing Road ends and the gravel road begins. If you turn left and look down the gravel road that leads to the cement plant, you can see the gate to the plant where the officer stopped and got out of his car.
The guy did see the officer drive his car down that road. He did not see any other car come out of that road. And, there are no other roadway escape routes there.
Nor did he mention seeing any breathless individuals scurrying back to their places of employment.
Maybe this will help get you there:
