Fox News reports that FBI investigators have matched DNA found on a recovered glove to the person captured on surveillance footage. Authorities are awaiting final laboratory results before entering the profile into a national database to determine the individual's identity.

Weekend updates
Pima County Sheriff's Department confirms to FOX 10 that the man detained in a traffic stop outside the Culver's restaurant on Feb. 13 was investigators' person of interest, and was cooperative.
PCSD said that while the search warrant was executed at a home near E. Orange Grove Rd. and N. First Ave. on the night of Feb. 13 based on a lead, no arrests were made. One person was questioned following a traffic stop, but they were not arrested.
"The source says after receiving a tip, authorities detained two males, plus one of their moms. The source said a warrant had been served," read a portion of that report. "The source cautioned that during a warrant execution, ‘technically everyone is detained.’"
The backstory:
Guthrie went missing on the night of Jan. 31 and was reported missing on Feb. 1 when she didn't show up for church. Since her disappearance, the FBI has released footage of her alleged abductor at her doorstep.
Guthrie's family has pleaded on social media for her safe return, stating they are willing to pay a ransom following reports of several notes demanding payment in bitcoin.

The Pima County Sheriff's Department and the FBI are working on finding Guthrie by searching rural and rigid terrain around the Tucson area, where Guthrie and her daughter, Annie, live. The sheriff's department is asking for anyone within a 2-mile radius of Guthrie's Catalina Foothills home to submit any footage they may have from Jan. 1 to Feb. 2 that they "deem out of the ordinary or important."
