MIAMI LAKES, Fla. — Every frame of the newly released video in the Nancy Guthrie case is being analyzed by criminologists and investigators across the country.

The nest camera footage shows a person of interest tampering with a camera by Guthrie’s front door.

It was released by the FBI Tuesday, after being recovered from residual data in a backend system since Guthrie did not have an account to save video.

Former Miami Police Chief Jorge Colina, who has more than three decades of law enforcement experience, said the video is telling.

“The mere fact that this person is surprised that there is a camera there is kind of shocking,” he said.

Colina said it appears the person was inexperienced and this was not planned out.

“They’re not professional, they didn’t spend a lot of time in preparing for this,” he said.

Colina points to the persons bulky clothing and large backpack, making them less mobile, which is not ideal for an abduction.

He said the person using a plant to cover up the camera is odd, and he does not believe the person is familiar with guns.

“The way they have their weapon exposed and where they carry the weapon is not common for somebody who handles a weapon,” Colina said.

Retired FBI Supervisory Special Agent Steve Moore also focused on how the weapon was carried.

“He’s holstering it in a holster that is made for a large frame revolver,” said Moore. “They don’t even match.”

Tuesday marked 10 days since Guthrie disappeared and one day since a deadline for a ransom with dire consequences passed.

Authorities have not named any suspects or persons of interest, but hopes the video will lead them to Guthrie and the suspect.
