See the link I posted above. The theory is that the owl swooped down and “attacked” her while she was out in the yard. Then she ran into the house and went upstairs in an attempt to get into her bathroom where she had first aid. Here is some of the pertinent info from the link I posted above:
“Here is the circumstantial evidence that supports the theory that Kathleen went out to the front yard, perhaps to place the small reindeers seen in the photos of the scene taken by the police, and that a barred owl inflicted those injuries:
- Barred owls were living in the woods by the Peterson house
- Barred owls are aggressive and can be dangerous, as explained in: Was an Owl the Real Culprit in the Peterson Murder Mystery?.
- Barred owls have attacked people on numerous occasions
- There were drops of blood on the outside walkway leading to the front door of the house, as shown in police photos
- There was a large smear of blood on the outside of the front door frame as shown in police photos
- At least two of the wounds on Kathleen Peterson’s scalp are in the shape of the talons of a barred owl, as shown on autopsy photos
- The tiny wounds on Kathleen’s face are consistent with the tip of an owl’s beak
- A feather was found on Kathleen Peterson’s body
- A twig was found in dried blood on Kathleen Peterson’s body
- There were numerous strands of Kathleen Peterson’s head hair, which the roots indicated had been pulled out (not cut), found in dried blood on her hands
- Kathleen’s head injuries are not consistent with her having been beaten by a blunt object or on a stair, as she had no brain injury or swelling, no subdural hematoma, and no skull fracture.@
