But they were on state land, not federal. So Virginia's state investigators handled the case. Right away, the similarities to the previous double homicide were hard to ignore. Both couples were killed in vehicles, presumably at night, right off the parkway in areas known as Lover's Lanes. One notable difference was the method of killing. David and Robin were shot, not strangled.

But authorities still suspected one thing. They had a serial killer on their hands. They moved forward with their investigation confident in this theory. But they didn't make much progress before tragedy struck again. In April 1988, seven months after the second Colonial Parkway attack, 20-year-old Keith Call and 18-year-old Cassandra Haley left a college party.

It was at Christopher Newport University, about 20 miles south of Williamsburg. Eyewitnesses said they took off together around 1.30 or 2 a.m. They were never heard from again. The next morning, park rangers discovered Keith's car. It was abandoned at an overlook by the York River, only a few miles away from where Kathy and Rebecca were killed in their car.

But this time, there were no bodies inside. The rangers called in the abandoned car to the police. Meanwhile, they searched the vehicle to figure out who it belonged to. They found a woman's shoe on the passenger seat floor and men and women's clothing in the back seat. Their best guess, Keith and Cassandra stripped and ran into the river for a late-night swim.

Except Cassandra's family swore Cassandra would never do that. She was scared of the water, not to mention it would have been freezing at that time of year. Keith's family was equally confused. The parkway was out of the way from both the party and where Cassandra lived. And Keith knew about the previous murders. He thought going out there was dangerous.

It made Keith's family think someone forced him and Cassandra to go there, or someone hurt the couple somewhere else, then dumped the car there. Due to the location, this case went to the FBI, who immediately began an extensive search. Helicopters looked from the skies. Police dragged the river. Bloodhounds on boats sniffed over the water.

You might be thinking, wait, doesn't water throw dogs off a scent? What about the books and movies where people run through creeks to escape bloodhounds? You wouldn't be alone. Some members of law enforcement were also skeptical. But it turns out there's a big difference between tracking someone who's alive and recovering someone who's dead.

Decomposing bodies underwater actually emit gases, body oils, and tissue that all make their way up to the surface. So a bloodhound can detect underwater victims. But this would only work if Keith and Cassandra were dead. In their search, the dogs didn't pick up a scent, which meant there was still hope of finding the pair alive. So the FBI homed in on suspects and made a critical mistake.

In 1988, the FBI sought any and all information related to the disappearances of Keith Call and Cassandra Haley. One tip led them to a man who was spotted driving a unique blue pickup truck along Colonial Parkway. Apparently, he'd stopped the car and approached a few couples. They recalled his memorable vanity plate, E-M-R-A-W, MRAW. The car was registered to Alan Wade Wilmer Sr., a.k.a. Pokey.

That's his chosen nickname, not ours. Wilmer was in his late 20s, white, fairly short, but muscular and strong from his work fishing. Wilmer farmed and sold oysters and clams. This explained the vanity plate, E.M. Raw, as in eat them raw. Wilmer also drove his own custom commercial fishing boat, the Denny Wade. He loved to hunt and was a winner in at least one local archery contest.
