New camera footage reveals potential clue near Nancy Guthrie's neighborhood: TMZ

The FBI has discovered new camera footage captured about five miles from Nancy Guthrie's home in Tucson, Arizona, with a man wearing a similar backpack, TMZ reported Thursday.

In the new video, it shows an unknown man carrying and wearing two backpacks — one with reflective straps — similar to the one in the footage released by the FBI this week of the suspect on Guthrie's porch who wore a ski mask, gloves and tampered with her Nest camera.

"Law enforcement sources tell TMZ ... the FBI is lasering in on the man in the video, who is both wearing and carrying backpacks ... right around the time of the kidnapping," the outlet reported.

Investigators have asked neighbors in the area to check their home security footage for two specific days and times, sharing an alert via Ring's Neighbor App, according to CNN.

"January 11 between 9 p.m. and midnight, more than two weeks before the 84-year-old went missing, and January 31 between 9:30 and 11, flagging a suspicious vehicle in the area around 10 a.m.," according to the alert.

Guthrie, 84-year-old mother of "Today" host Savannah Guthrie, went missing sometime between late Jan. 31 and early Feb. 1. She was last seen following dinner with her family.

The Pima County Sheriff’s Department’s tip line has received more than 18,000 tips since she went missing.
