Jill Sidebotham and her two-year-old daughter, Lydia, missing after leaving for a camping trip. The invitation to go camping came from Lydia's father, Nicholas Hansen, and Sidebotham's ex. Sidebotham and Hansen planned to return from their trip to Phillips, Maine, on June 30. When they didn't, Sidebotham's family members report her missing.

On July 2, Sidebotham, Hansen, and their daughter are seen on video at a Mexico, Maine, Walmart. No one has heard from them since--not even Sidebotham's 10-year-old son Brayden.

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.

Guest Bios:

Bill Thomas is a victim advocate and the brother of Cathy Thomas, one of the original victims of the Colonial Parkway murders. For nearly four decades, he has worked with law enforcement, forensic experts, and journalists to seek answers in his sister’s case and accountability for all affected families. Bill is co-host of the podcast, "Mind Over Murder," where he focuses on cold cases, investigative transparency, and the systemic challenges families face in long-term homicide investigations.

Kristin Dilley is a true crime podcaster, researcher, writer, and teacher based in Williamsburg, Virginia. Kristin has worked alongside Bill Thomas for more than seven years and is the co-host of "Mind Over Murder," where she examines cold cases with an emphasis on evidence, patterns, and victim-centered accountability.
