That work includes the challenging effort of retrieving any additional images of the suspect from the back-end of Guthrie’s video security system, the official said.

At the agency’s Tucson field office, the command post remains fully active, the official said. Some personnel are being rotated through the post to keep “fresh eyes” on the case reviewing evidence, a second official said.
Pima County Sheriff Chris Nanos said in an interview Friday that he believes investigators are getting closer to identifying some of the articles of clothing worn by the masked man captured on Guthrie’s security camera and released last week by the FBI.
His backpack — a 25-liter Ozark Trail Hiker Pack — was previously identified as a product sold exclusively at Walmart.

In addition to trying to identify the suspect’s pants, shoes and jacket, Nanos said, investigators are visiting gun stores and asking about the holster he was seen wearing and the firearm he appeared to be carrying.
The department is also awaiting an analysis from partial DNA found at Guthrie’s home.
