PARADISE TOWNSHIP, PA — Shelter, water and food, in that order, are the chief concerns of accused cop killer Eric Matthew Frein as he navigates the wilderness while dodging police, a defense department analyst and survivalist said.
Wilderness survival boils down to the rule of threes, said Bob Collins, a Defense Department analyst from Ambler who teaches survival classes for Montgomery County Community College and Bucks County Community College.
The human body can survive three minutes without oxygen, three hours of intense heat or cold exposure, three days without water and three weeks without food, said Collins, who is trained in survival by the U.S. Air Force, where he served 16 years after 10 years in the Army.
Collins dismissed the idea that Frein is living fully off the land. If he survived three weeks without a food cache, it would put him into a category of survival expert on par with Collins or others like him.
