I got a feeling the escapees were in that recreation cabin at Owl’s Head many days earlier than last Sunday and are long gone from the area. Most healthy individuals moving thru that type of terrain can cover 3 miles an hour. The witness that saw someone running probably spooked a local opportunist who noticed the place was not secure from the initial break-in and ran off when the witness drove up.
These fugitives planned this escape for some time, took many days cutting thru each obstacle from the prison cells to the manhole lock and were methodical the whole way. They could be out of the country by now.
The highly skilled search teams have been combing that area with a tight perimeter for close to a week. They have an incredible arsenal of technology including infrared heat detection, night vision goggles and good ole blood hounds. If the prison escapees were in that perimeter they would have been detected by now.
