What has happened by the time the police footage is shown? After Erin escaped and killed the sheriff apolice footage of the area is shown as they collect evidence and filming a walk-through, as if the house has been abandoned for years, but it's only a day after. What has happened to the rest of the Hewitt family with the exception of Leatherface who escaped? How did the police only find out about the Hewitts then?

I think it would be great if they did a part of three of them on the run.
