On January 18 2012, a contractor was walking along a road In Dover Township Pennsylvania, called Schoolhouse road in York County when he noticed a plastic bag there.  

It was heavy and had a weird kind of liquidy consistency. 

At first he said he thought it might be a dead animal but then he saw the blood and what looked like long, gray human hair and skin he called the police…he realized what he was looking at was a human scalp.

The lab confirmed that this was human but they ran the DNA and could not find a match to anyone in the system. So the head became a John Doe officially but unofficially, the Foodsaver bag case. 

So that bag and that strip of skin remained in that crime lab.

Until five years later. This would lead them to a 67 year old diminutive grandmother who looked like a sweet little lady  - and who was guilty of pathological lies, horrific murder - and who some believe could even be a black widow.
