More than two months after Nancy Guthrie‘s disappearance, officials still have no suspects in the puzzling case. But DNA expert CeCe Moore suggests that progress could be made if authorities return to Nancy’s home to retrieve more DNA samples.
Prior samples taken from Nancy’s home were “mixed” and contained genetic material from more than one person, which Moore says is common. “I think there are a lot of efforts to be able to improve our ability (to deconvolute DNA samples) because we run into that so often with sexual assaults, or as the technology becomes more sensitive with transfer DNA, the ability to detect the tiniest amount of DNA that someone leaves behind really increases the likelihood you’re going to get a mixture, right? Like on a doorknob, for instance,” she explains on Brian Entin Investigates.
