Maybe. I took some photos the other night in my "cheap" ones to demonstrate my left foot theory. It worked, but I'm embarrassed to put them up because of ALL the dog hair on the floor! I have two siberian huskies as you see from my avatar, and OMG, when I put the lamp on the floor for lighting! smh.
I will try again after I clean, but what I figured out from it is that the black thing in front of Travis is a black house shoe or mule. It covers the top of the foot, but slopes down, so if a foot is in the shoe and could be seen, one would see the side of the foot. If you look at the very top of the shoe in the murder photo, you will see that there is a shadow there, indicating the shoe is empty. Behind it, Travis' body, and his blood spilling over his shoulder, is evident in that white space there. If you look at the hem of the pant leg and follow it closely down the slope of the shoe, you can see the shoe's mule-like design.
Back at the top of the shoe, there's what appears to be a movement trail of the pant leg, just like we see movement trails in that new, brighter ceiling picture.
So this is what I think happened. However the camera got there, falling out of her pants pocket or whatever, she was pulling, or somehow struggling with Travis. Whatever movement she was doing caused her to come out of her right shoe, which is sideways in the photo. Her right foot (now minus the shoe) could have hit the camera or it's right next to the camera, but her left foot landed, perpendicular on the back of the right shoe. We can't see the rest of the left foot because it is out of the picture viewing area. (It might or might not have a shoe on it, but I think it does because of those bloody foot stamping prints at the base of the shower. It looks like she was pushing against the shower with that foot to shove the body into the shower.)
I took a picture just like this with and without my right foot in the picture. Because the camera is so close to the subjects, the right foot doesn't have to be far away at all. For my purposes, I left my whole left foot in it, but then I made a new picture, cropping my foot out. Her pants are also long. We can't see under them. Mine that I used are incredibly long. I rolled them 3 times to hike them up enough to make the picture take note that it was the left foot for illustration purposes.
I'll post them anyways. Dog hair is dog hair, huh?

I put in there the shoe I used (the heel is bent down. It's not really a mule), the murder photo, the murder photo with a highlight on where I'm saying I determined there is no foot actually in the shoe, the photos of both my feet in the my theory shot, and a cropped photo of just my left foot with most of the actual foot removed. I'm adding pics of possible shoe impressions and foot impressions from the evidence.
Just my theory. Again, excuse the dog hair. With two huskies, I can clean every hour and not get it all.
