(NewsNation) — The FBI has now taken cell phone tracking to the next level with a system called the Cellular Analysis Survey Team, or CAST.
Former CIA and FBI agent Tracy Walder explained Tuesday on “Banfield” that towers around the University of Idaho campus could hold important clues to the whereabouts of victims in their last hours of life.
Walder has used cell phone towers to locate suspects in the United States and abroad, including terrorists.
She says CAST technology works and is “surprised we haven’t cracked (the case) because of the propensity of 20-year-olds to use cell phones.”
“I think cell phone data would be very, very critical in terms of locating Xana (Kernodle) and Ethan (Chapin) in particular, but on the other hand, the absence of data could also indicate a suspect,” Walder. said.
In the future, Walder believes the technology could at least help identify a person of interest in the case.
