Police in Nancy Guthrie investigation say glove DNA didn’t match anything in national database

DNA from gloves found a few miles from the Arizona home of Nancy Guthrie did not match any entries in a national database, authorities said Tuesday, the 17th day of her disappearance.

“There were no DNA hits in CODIS,” the Pima County Sheriff’s Department said, referring to the national Combined DNA Index System.

“At this point, there have been no confirmed CODIS matches in this investigation,” the department said, suggesting that other DNA samples had been put through the system.

CODIS is a storehouse of DNA taken from crime suspects or people with convictions. Any hits could identify possible suspects in Guthrie’s disappearance.

Investigators, meanwhile, were seen inspecting exterior cameras at a neighbor’s house Tuesday. Vehicles were also arriving and departing from Guthrie’s Tucson-area home while a thick line of news media watched from the street.

The 84-year-old mother of NBC “Today” co-anchor Savannah Guthrie was reported missing from her home on Feb. 1 after spending the previous night with family, police said. Her blood was detected on the porch.

A porch camera recorded video of a man with a backpack who was wearing a ski mask, long pants, a jacket and gloves. The FBI said the suspect is about 5 feet, 9 inches (1.75 meters) tall with a medium build.

Gloves were found about 2 miles (3.2 kilometers) from Guthrie’s home. The FBI has said that the gloves appeared to match those worn by the man in the video.

“There is additional DNA evidence that was found at the residence, and that is also being analyzed,” the sheriff’s department said.

In addition, the department said it’s working with experts to try to locate Guthrie by detecting her heart pacemaker.

Parsons Corp. said its BlueFly device, which weighs less than a pound (.45 kilograms) and has a range of up to 218 yards (200 meters), can detect signals from wearable electronics and medical devices. The company said the technology has been used from the air and on the ground in Arizona. It declined further comment about the search.

Savannah Guthrie posted an Instagram video Sunday in which she issued an appeal to anyone with information about what happened to her mother.

“It is never too late to do the right thing,” she said. “And we are here. And we believe in the essential goodness of every human being, that it’s never too late.”
