Nearly four decades after the Colonial Parkway murders first shocked Virginia, new DNA links have expanded the known scope of the case while raising questions about investigative accountability.
In this episode of "Zone 7," Sheryl McCollum is joined by Bill Thomas, whose sister Cathy Thomas was one of the original victims, and Kristin Dilley, his long-time investigative partner and co-host of the podcast, "Mind Over Murder."
They walk through the latest DNA identifications tied to Alan Wade Wilmer Sr., the procedural barriers that keep his profile out of CODIS, and the growing divide between state-level momentum and federal inaction.
Their discussion centers on what happens when evidence advances while communication and action stall.

Brian Walshe has been sentenced to life in prison without the possibility of parole.
This after a Massachusetts jury finds him guilty of killing and dismembering his wife, the mother of their three children, Ana Walshe.
Ana vanished on January 1, 2023.
Walshe, 50, initially plead guilty to improperly disposing of her body and lying to police. He had changed his plea on the two charges before jury selection got underway for the trial, while maintaining that he did not kill her.
Prosecutors say the 48-year-old husband dismembered Ana Walshe and discarded her body in multiple trash cans in the area. Police have recovered blood-stained items from the home, including a hacksaw.
Ana's body has never been found.
