The body of Margaret "Maggie" Sniegowski is found by a farmer, dumped along a central Indiana highway.  Police say the teen had been dead for several days. At the time, however, no one knew who the girl was and it would be 20 years before the 17-year-old was identified,  thanks to DNA technology. 

Boone County Coroner Justin Sparks said an autopsy ruled her cause of death as undetermined.  Sheriff Mike Nielsen said there were indications Sniegowski may have been strangled. The focus now is to find who killed her.

Teen Girl Body Dumped off I-65,  Haunts Sheriff

https://api.omny.fm/orgs/e73c998e-6e60-432f-8610-ae210140c5b1/clips/6538b9a2-1334-4f49-b1d8-aee5000ab31e/transcript

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.
