"Shaw said the only real solid piece of evidence they have
the very small droplet of blood discovered outside the Exxon station that was determined to have belonged to Heeringa didnt really answer anything."
"The only thing anyone allegedly saw was an obscure silver or gray minivan near the gas station around the time Heeringa was last seen inside the business. A sketch was created based on a witnesses description of the driver of that van, but police cant say without a doubt whether that man or the van is responsible for Heeringas disappearance."
So there ya go............they cannot determine/say without a doubt if the man in the sketch or van is responsible for Jessica's disappearance.........
Where are you Miss Jessica?
IMOO.
