Yashim and alabaster thanks for the support. You've both had great insights too. Yashim, I think you were the one that translated the article, on which I based my scenario, that SS was seen photographing a group of the homeless and then alone with Z. A shout out also to the websleuth that within minutes of seeing the video of SS walking down the street in the red shirt, said I think there was a sex crime behind this.
I think SS being 9 going on 32 ( see #2 in my scenario) did lead to SS's demise.
Just to add to the scenario a few new pieces of information:
1. Last night someone here said SS crossed the road to take picture of the doors of C. . That's what got her to cross the street. Then she was surrounded by the "nice" and charming group of homeless. She's thinking like a 9 year old. "Oh, they're so nice" and she's left with the especially nice Z.
2. Z was a scavenger. I think SS looked to him to be a vision of loveliness. I think he thought, first I'm going to rape her. Then I'm going to take her jacket, phone, and Ipad to sell.
3. Add also to the scenario that SS had been filmed walking like a schoolgirl, swinging her jacket as she walked to the dangerous part of town. She had gotten the text from Taylan , with whom she was smitten, that he would be joining her. I think she was going to stay on the other side of the road until Taylan came, but then got carried away with the photographs of the doors, the homeless, and then the oh so helpful Z.
4. I'm leaning more toward Z dragging her body at night away from the murder site. I think he wiped the body clean of fingerprints, as best he could, and that's why at first LE was saying it looked "professional." But he didn't get under SS's fingernails.
What do you think?
I think that the woman on the video could be anybody, and at the start of the video the person looked wearied. If it was SS that's because she had walked so far and still did not seem to be getting anywhere.
The person got hot and swung the jacket in frustration rather than in a mood of carefree schoolgirlishness.
T. was already bored with her and was not going to meet her.
If she felt a momentary aversion to Z she changed it to some 'Christian' ''poor man, let me not look down on him'' attitude.
As to your suggestions regarding what Z was thinking, yes, seems a probable scenario.
