The M-Vac was used to collect DNA material from items in the Angie Dodge murder. It found DNA on both her clothing and a stuff animal that matched a stain that had also been found at the crime scene. However, the DNA did not match Chris Tapp's DNA, who had been convicted 20 years earlier. He was resentenced in a plea deal and release from prison. The news story is of Chris Tapp being introduced to the M-Vac and shown how it works. Dr. Greg Hampikian of the Idaho Innocence project also comments on the M-Vac's role.
