Getting your Trinity Audio player ready…More than six months after Nancy Guthrie’s initial kidnapping, authorities’ search for the mother of “Today” host Savannah Guthrie seems no closer to a conclusion, with no arrests made in the case. The investigation may have failed to gain momentum in its crucial first hours due to the response of the Pima County Sheriff’s Department, according to a report by the Wall Street Journal published Saturday evening. David Stivers, the appointed head of homicide, was reprimanded two months before Guthrie’s kidnapping for “poor judgment” and his role in delays in securing evidence in a different case. Additionally, the Journal reported that the sheriff’s surveillance search-and-rescue aircraft did not begin its search until 6:30 p.m. — several hours after its initial missing-person report and too late to search during daylight hours. The Pima County Sheriff’s Department did not initially respond to a request for comment.
