The investigation into Nancy Guthrie’s disappearance continues as authorities work to uncover what happened and identify who may be responsible. A veteran homicide prosecutor has now weighed in on a major question surrounding the case: whether a murder case can move forward if Nancy Guthrie’s remains are never recovered. Tad DiBiase, a prosecutor known for handling “no body” homicide cases, said that while finding a body is always valuable evidence, a case could still potentially succeed without one, as per a report by Parade.
