The criminal complaint:

"14. Hiker #1 and Hiker #2 were interviewed by investigators with the Smyth County Sheriff's Office on May 11, 2019. Both identified Jordan as being the individual who had approached and chased them with a knife and had a picture on a cellular phone of Jordan from his prior incident in Tennessee."
I took this to mean that either Hiker #1 or Hiker #2 had taken a picture of the defendant during a prior run in with him in TN. If not, why would the FBI agent include this clause in the affidavit? What other photo could they have had of the defendant? Were hikers texting pix of the defendant to each other for situational awareness? If the photo was his prior booking photo, the agent would have written exactly that, as the booking photo is already a gov't document identifying the defendant and would thus constitute a clearer identification of the defendant than some random picture not already in police custody. Maybe I read too much into it.
The defendant will soon be indicted by a federal grand jury. The indictment will undoubtedly contain more details.
