Pima County Sheriff’s Department confirmed that investigators are analyzing biological evidence found at Nancy Guthrie’s residence.
DNA profiles are under lab analysis, said Angelica Carrillo, a spokesperson for the sheriff’s department.
“The number of profiles, and other related details remain part of the active investigation,” she said in an email.
The sheriff’s department also announced a $102,500 reward for a tip leading to the arrest of the suspect in Guthrie’s disappearance – thanks to an anonymous donation made on Wednesday, Feb. 18.
88-CRIME received an anonymous donation of $100,000, allowing the program to increase the reward for this case to $102,500, Carrillo said.
This is in addition to the $100,000 reward that the FBI is offering for tips leading to Guthrie’s recovery or the arrest and conviction of the person responsible for her disappearance.
Officials would not say whether they are working with Mexican officials should Guthrie or a suspect have traveled across the border.
The New York Times reported earlier on Wednesday that, according to an unnamed security official, the FBI contacted authorities in the bordering Mexican state of Sonora to investigate an alleged “purchase” related to Guthrie’s case.
But that line of investigation was reportedly ruled out by the FBI, according to the report.
The Pima County Sheriff’s Department said Tuesday that DNA evidence from gloves found two miles away from Nancy Guthrie’s home “did not trigger a match in a national DNA database and did not match DNA found at the property” in a social media post on Tuesday.
But DNA evidence that was obtained from the property is still being tested.
The sheriff’s department sent out a statement on Tuesday that investigators were working with experts and the manufacturer to locate the 84-year-old’s pacemaker.
Investigators are also working with Walmart management to identify the buyer of an Ozark Trail backpack worn by the armed suspect who was seen approaching Guthrie’s front door in surveillance footage.
Officials believe he is 5 feet 9 or 10 inches tall with an average build. Law enforcement is also canvassing local gun shops to determine whether the suspect in the video is familiar.
Evidence obtained from two recent search warrants is also still being processed. Individuals who were questioned have been released and no arrests have been made.
The sheriff’s department has not confirmed the number of leads that investigators are actively pursuing but says that at this point, Guthrie’s family members have been ruled out as suspects.
Guthrie is the mother of “Today” show host Savannah Guthrie. She was taken from her Catalina Foothills home on Sunday, Feb. 1, reportedly against her will.
Savannah Guthrie attended the University of Arizona and worked for Arizona Public Media’s Arizona Illustrated in her early journalism career. Her mother worked for the university from 1990 to 2007, a spokesperson confirmed.
