I was doing some painting today, touching up some decorative ironwork on the door of my house. I was using a small can of black exterior latex paint and an artist's paintbrush, slightly smaller than the one found at RZ's death scene.
I didn't get any paint on myself, only a small amount on my hands. At one point, I had too much paint on the brush and it dripped as I was painting. It landed on the porch in front of the door. It dawned on me that I was painting in the same manner someone had painted on the door to RZ's death room.
I looked at my posture as I painted and realized that most people, using that kind of brush and painting just above eye level, would probably not get paint on their chest. They would have to be painting with a lot of paint and in a wild manner to get it on their neck, chest or midsection. Any drips would fall straight to the floor in front of the door.
I decided to see what posture I would need to be in for paint to drip or splash on my chest. I found I had to be right up next to the door, with my nose practically touching the surface to get my chest close enough for paint to drip there. RZ wouldn't likely have done that, nor would she have brough the paintbrush near her face or mouth - the only other likely scenario for getting paint on her chest.
I also noticed the small amount of paint I got on my hands was on the inside of my hand, on the palm and fingers, not on the back of my hand. If you view RZ's death photos in the photo sticky link above, you'll see she had paint mostly on the back of her hand.
Considering the paint used on the door was a thicker type of artist's paint from a tube vs. the thinner stuff I was using, I don't see how that could have landed on her chest. And if the paint was flying around, why didn't some of it land on the floor below the door, the most likely place for drips.
I'm kind of tired from a lot of chores today, but will check the details about the paint and death scene in a little bit. It might be worthwhile to try duplicating the message painting scenario.
ETA: The Zahau family attorney's statement also said there was black paint on the rope tied around RZ's neck. Please explain how someone, in the nude, with a rope tied to the bed on one end and wrapped around their neck gagging them and a tshirt gag wrapped on top of that goes over to the door and paints a farewell message before tying their feet and hands, then jumping off the balcony.
Betty P, you've made valid points and I greatly appreciate you valiant effort at "experimenting" with the painting on a door. I also agree that the paint on Rebecca was "staged" by her murderer(s). However, just as we can't use the SDLE female officer's demo in tying her hands behind her back to conclude that Rebecca had bound her own hands behind her back, we cannot exactly use you to demonstrate what Rebecca could or could not do, or what would or would not have happened had Rebecca engaged in the same painting activities that you did, or that she even engaged in such a paint job. Each human being is unique and in that sense, it's impossible to conclude how/what/when/if, etc. would have happened to Rebecca had she done the same activity you did. Even identical twins with same DNA possess different behaviors/mannerisms given similar circumstances.
Having said that though, we can *estimate* what might have happened with Rebecca to the best of our abilities. But we should point out the physical differences between you and Rebecca when offering you as a representative of what might have happened to Rebecca.
E.g., are you and Rebecca of about the same physical size in height, weight, etc.? Are you as fully endowed in the chest area as Rebecca (given that her first autopsy by the SD ME reported that it was "obvious" she had breast implants which for the life of me, I don't know why a doctor would use that specific nonmedical term of "obvious" instead of simply stating there were medical signs of surgery having been performed on her breasts. How did he know she didn't have cancer or had a tumor removed from her chest and had reconstructive surgery? Did he even read her medical history before performing his autopsy or did he just naturally *assumed* certain things about Rebecca or did a POI such as D/N/A/J plant those ideas in SDLE's head when they came to identify her body at the crime scene or when they were interviewed)?
IMO again I believe all the black paint on Rebecca was smeared on her body by the murderers. However, I can see a murderer thinking, well, Rebecca has those large implants, so I'm going to mock her by smearing black paint on both of them, and also smear some on her neck and the rope and parts of her fingers/hands to make it appear as if Rebecca was such a klutz that she'd drip drop the paint all over herself. Also if someone is large-chested, I can perhaps see paint dripping off the brush or door at some point onto their chest area if they were using an unusually LARGE amount of paint on the paintbrush (like an intoxicated murderer might have). I think that is what the murderer(s) wanted some gullible peeps like SDLE to believe. But as you said, the chances of that happening are virtually nil compared to dripping paint onto the much larger surface areas of the FLOOR.
Re: paint on the rope around Rebecca's neck. Again I think the murderer(s) smeared the black paint there to "stage" the alleged suicide. However, if another person who was not mentally healthy like Rebecca committed suicide, I could see that mentally disturbed person painting the message on the door first and then doing the rope binding, t-shirt gagging, etc. after. And that the mentally ill person did not the rope binding, etc. before the paint had dried on their hands.
But again, we're talking specifically about Rebecca. And her mental history is such that there leaves NO room for speculation that she did any of the door painting or rope binding, noose, t-shirt gag, etc. because she had NEVER in her entire 32 years of life suffered ANY depression nor did she ever contemplate or carry out any form of suicide attempt or rope-binding on herself/others, nor gagging, etc. So to me, it is OBVIOUS that Rebecca did NOT do any of these humiliating things to herself. It is equally obvious to me that someone else, i.e., her MURDERER(S), did them to torture, embarrass/mock, and hang Rebecca.
