The FBI and the Pima County Sheriff’s Office want to question a man seen carrying a backpack in surveillance video recorded just miles from Nancy Guthrie’s home around the same time she disappeared that night, a source familiar with the investigation confirmed to Fox News Digital.

TMZ obtained Ring camera video of a man with a backpack approximately five miles from Guthrie’s house.

Fox News Digital is told the Pima County Sheriff’s Office and the FBI are reviewing the video because the man seen in the video appears to be dressed similarly to an individual captured in a separate doorbell video at Guthrie’s home, including wearing a backpack.

Authorities have not yet determined if the man is in any way related to the Guthrie case. However, the source said investigators would like to speak with the man as they continue looking into the matter.
