Cold cases that have gone cold for too long. Each season investigates a single case in forensic depth — the victims, the evidence, the investigators, and the failures of a system that sometimes lets killers die free. Season 1 covers the Colonial Parkway Murders, a series of brutal killings along Virginia's historic parkway between 1986 and 1989.

Wilmer lived free until 2017, dying at 63 in his Lancaster County home. Then forensic genealogy cracked the case. January 2024: Knobling and Edwards confirmed. November 2025: Laurie Powell confirmed. January 2026: Thomas and Dowski confirmed. He was guilty. He will never be prosecuted.
Alan Wade Wilmer Sr. A Virginia waterman and hunter who fished the waters of the exact geography where these murders happened. In 1988, the FBI searched his home and found handcuffs and a gun. They gave him a polygraph. He passed. They let him go.
Every crime scene told the same story: the victims complied. Windows down. Wallets out. No struggle. The law enforcement impersonation theory — how a badge is the most dangerous weapon a predator can carry.
September 5, 1989. Daniel Lauer and Annamaria Phelps were driving to Virginia Beach. Their car was found facing the wrong direction at a rest stop. Six weeks later, hunters found their skeletonized remains wrapped in a blanket a mile away. The last known case. Still officially unsolved.
April 10, 1988. Keith Call and Cassandra Hailey went on their very first date. Their car was found on the Colonial Parkway with his clothes in the back seat, his wristwatch on the dashboard. Bloodhounds tracked their scent to the water. Their bodies have never been found.
September 1987. David Knobling and Robin Edwards — an eighth grader who snuck out at midnight. Found four days later on the bank of the James River. Both shot. Both execution-style. The FBI draws a line between this and 1986.
The last night of Cathy Thomas and Rebecca Dowski. A Naval Academy graduate and a William & Mary student. The computer lab. The three days they were missing. The diesel fuel, the rope, and the FBI's private warning to Cathy's brother four days after her death: the killer may be in law enforcement.
An introduction to the Colonial Parkway — 22 miles of national park highway through old-growth Virginia forest. October 12, 1986: a jogger finds a white Honda Civic off the road. What the first trooper found inside would begin the longest cold case investigation in Virginia history.
