“This backpack is exclusive to Walmart and we are working with Walmart management to develop further leads,” Nanos said.
The suspect’s clothing “may have been purchased from Walmart but is not exclusively available at Walmart,” the Pima County Sheriff’s Department said in a statement Monday. “This remains a possibility only.”

Investigators on Sunday announced that a glove discovered near the Guthrie home has been sent for DNA testing. The FBI said that it received preliminary results Saturday and was awaiting official confirmation. The development comes as law enforcement gathers more potential evidence and as the search for Guthrie’s mother heads into its third week. Authorities previously said they had not identified a suspect.
Nanos said on Monday that members of Guthrie’s family, including siblings and spouses, are not suspects.
“The family has been nothing but cooperative and gracious and are victims in this case,” Nanos said in a statement.
Authorities have expressed concern about Nancy Guthrie’s health because she needs vital daily medicine. She is said to have a pacemaker and have dealt with high blood pressure and heart issues, according to sheriff’s dispatcher audio on broadcastify.com.
The FBI said the suspect in the surveillance footage is a man about 5 feet, 9 inches tall with a medium build.
