dailyloe.com – DNA expert CeCe Moore suggests progress could be made in the Nancy Guthrie disappearance case if authorities return to her Arizona home for more DNA samples. More than two months after Guthrie vanished, officials still have no suspects. Moore believes new forensic technology could analyze complex genetic mixtures found at the scene.
Prior samples taken from Guthrie’s home were ‘mixed’ and contained material from multiple people. Moore explains this is common with sensitive modern DNA detection methods. She stated these methods increase the likelihood of finding mixtures on surfaces like doorknobs.
Companies working with law enforcement are developing new mixture deconvolution software. This technology helps analyze complex DNA samples. Nancy Guthrie’s case is reportedly a top priority for these efforts.
Moore points out current techniques struggle with whole genome sequencing data. However, she remains hopeful officials will get another chance. Finding a good DNA source in the home could break the case open.
If a solid DNA sample is not found at Guthrie’s home, Moore hopes a second crime scene is discovered. Another search for DNA could then be performed there. She is certain the kidnapper left DNA somewhere inside the residence.
The case remains puzzling after more than sixty days. Moore’s comments were made during an interview on Brian Entin Investigates. Advanced DNA analysis now offers a potential path forward for investigators.[]
