Suspect in Nancy Guthrie case had been to the house before the night of her disappearance, source says

The image the FBI released of the suspect at her front door, without a backpack, was captured by her Nest doorbell camera on a day prior to the suspected abduction. It is unclear how many days before Feb. 1 the video of the man without a backpack was taken.

The FBI released the images and video on Feb. 10 and asked for the public’s help in identifying the man seen in the videos. So far investigators have not identified a suspect in the case.

Pima County Sheriff Chris Nanos told CBS News that the information about the timing of the video of the man not wearing a backpack is not coming from the Pima County Sheriff’s Department or the FBI. 

In a previous statement from Feb. 10, Nanos said, “The FBI and Pima County Sheriff’s Department have been working closely with our private sector partners to continue to recover any images or video footage from Nancy Guthrie’s home that may have been lost, corrupted or inaccessible due to a variety of factors, including the removal of recording devices. The video was recovered from residual data located in backend systems.”

A spokesperson for the FBI did not immediately respond to a request for comment.

A spokesperson for Google, the company that owns Nest cameras, had previously told CBS News that it is assisting law enforcement in an investigation but could not provide further details due to the ongoing investigation.

CBS News reached back out to Google about when the earlier video of the man without the backpack was taken, but a spokesperson did not immediately respond to a request for comment.
