Nancy Guthrie live updates: DNA from glove found near home will be added to national database

The FBI shared images Tuesday retrieved from backend systems of Nancy Guthrie’s doorbell camera showing a masked and armed person at her doorstep.

Just today, a source familiar with the matter told NBC News that a glove worn by the person seen in the video appears consistent with a glove recovered roughly 2 miles from Guthrie’s home.

Here’s what we know so far about the suspect in her disappearance:

• The FBI has described him as a man with an average build.
• He was described as being 5 feet, 9 inches to 5 feet, 10 inches tall.
• He was also seen wearing a black, 25-liter Ozark Trail Hiker Pack backpack.

The media presence on Guthrie's street appears to have grown since yesterday. Several news crews are positioned along the block, and a sheriff's deputy remains parked in the driveway of her home. A drone flew overhead.

At one point, a man stopped briefly to drop off flowers at the house before he left.

FBI testing DNA found on glove consistent with type seen on Guthrie doorbell video

A glove containing DNA evidence was recovered roughly 2 miles from Guthrie’s home and appears consistent with a glove worn by a person seen in a doorbell camera video from the morning she disappeared, according to a source familiar with the investigation.

The glove was one of 16 recovered over several days in areas surrounding Guthrie’s home, the person familiar with the matter said. Investigators have determined that most of the gloves belonged to searchers combing the area for evidence.

Following some additional testing today, the person said, the DNA profile, which matches that of an unknown male, will be added to the national DNA database managed by the FBI, called CODIS, which stands for Consolidated DNA Index System.

DNA samples can be submitted to the massive database for possible matches. CODIS has 19 million offender DNA profiles and over 1 million forensic profiles, according to the FBI.

But a match would not necessarily break the Guthrie case. The FBI says the DNA matches a male, and it has not indicated a match to Guthrie. Whoever left the glove would not necessarily be a potential suspect and might not even be related to the case.

Law enforcement experts say that at best it could be a helpful lead.

At St. Andrew’s Presbyterian Church, where Guthrie had connections, her name was mentioned at least once during prayers this morning.

“Lord, you’re with Nancy even now. We pray for her,” a speaker said. “Guide those who are seeking to find her. ... Let your peace wash over Nancy’s family.”

Few churchgoers were willing to speak publicly afterward, and the atmosphere was subdued.

At a farmers market near Guthrie's home this morning, vendors said her disappearance has left many in the community unsettled and searching for answers.

Sandra Carey, who lives in Amado just south of Tucson and sets up her produce stand at the market every weekend, described the area as friendly and tight-knit. She called it "a great community" and said she's struggling to make sense of what happened.

“How can someone kidnap an 84-year-old woman?" she said. "I don’t know what’s going on. The pictures of the masked man at the door, the whole thing is just scary.”

Phoebe Waybright, who lives in Vail and runs a pet treat stand at the market everyweekend, called the case “mind-boggling.”

The neighborhood around Guthrie’s home remained largely quiet this weekend. A sheriff’s deputy was stationed in the driveway last night, and media vehicles continued to line the street.

Community members continued to leave yellow flowers outside the home, a visible sign of support as the search stretches into its second week.

The search for Nancy Guthrie stretched into its 14th day today, with investigators continuing to pursue leads after a recent court-ordered search did not result in any arrests.

Two sources familiar with the investigation told NBC News that authorities are leaning away from considering as a suspect the man whose home was searched Friday night. Investigators are also leaning away from a man named Carlos, who was stopped in a car earlier this week, as a suspect, the sources said.

In addition, investigators are leaning away from any relatives of Guthrie as suspects, according to the sources. They cautioned that no one has been officially ruled out, and investigators continue to focus on other leads.

Law enforcement officials executed a federal search warrant at a home near Guthrie’s residence at East Orange Grove Road and North First Avenue on Friday night. Authorities confirmed that no arrests were made following the search. Deputies also conducted a traffic stop connected to the case, questioning one individual, but no one was taken into custody.
