Nancy Guthrie did not leave her residence without putting up a fight, as per a former FBI agent.
"I believe that Nancy fought him, either inside the door or just outside, depending on where the first appearance of this blood splatter evidence is present- a former FBI agent mentioned as he investigates the case privately.

Clemente was seen discussing with local media outlets about the chilling footage depicting a trail of blood leading the way from the 84-year-old's front door.
Investigators determined, based on evidence at the scene, that Savannah's mom is the victim of a targeted kidnapping.

Nancy was last seen at her home in Tucson, Arizona, on the evening of January 31, and is said to have been taken during the early hours of Sunday.
At that point, the detective shared how the suspect either blitzed with overwhelming force, punched in the face or the nose, and she started to bleed. The renowned FBI agent said she either coughed up blood after hunching on her knees or bending over, which is why the pattern was seen in the picture. The point where it disappears is the point she was picked up and carried away with her head up.
