On the evening of July 1, 1989, 32-year-old Pamela J. Webb left a family gathering in Winthrop, Maine, to drive to Mason, New Hampshire, for the holiday weekend. She drove a 1981 blue Chevrolet pickup truck and was traveling with her dog, Thumper. Pamela entered the Maine Turnpike in Augusta at 9:52 p.m. but never reached her destination.

Pamela’s pickup was later found abandoned on the southbound side of the Turnpike in Biddeford with a flat passenger-side rear tire and a spare leaning against the tailgate. Investigators found signs of a struggle nearby, including bloodstains on the pavement. Her purse, a Bible, and other personal items remained in the truck; the dog was unharmed. Between 75 and 100 people reported seeing the disabled vehicle on the highway.

Her boyfriend reported her missing on July 2, and on July 18 construction workers found Pamela’s skeletal remains in a wooded area off Route 3 in Franconia, New Hampshire, far from where the truck was located. The medical examiner ruled her death homicidal, though the condition of the remains prevented a more specific cause of death. No arrests have been announced and the case remains unsolved.

If anyone remembers seeing that pickup, Thumper, or unusual activity on the Maine Turnpike that night, please share what was seen.
