This is what I think transpired:
1. Too bad SS didn't keep her more androgynous look on the 21st, with her hair tucked into her unisex cap. She dress nicely since she had hoped to meet Taylan, and that is her on the video.
2. People had described her as adventurous. (Who among us would sleep on the couch of an instagram acquaintance in Amsterdam?) She was also trusting and naive. She thought, though , she was a good judge of character. Early on her minister described her as 9 going on 32 (or whatever her age is.) This trait alone led to her demise.
3. Perhaps Taylan had mentioned the night before about going to the walls and trying to get portraits of the people there.
4. She decided that since Taylan didn't show, today would be her last day to capture great photos.
5. She went to the walls and assumed it to be safe. It was daylight, and a traveled road. Perhaps she was on the other side of the road. Z appeared and seemed charming, safe, and cooperative. Perhaps he motioned kindly for her to come across the road. He may have motioned for her to come into his cave.She did not feel brave enough to do this, but she may have glanced in.
6. Z then pulls her in to rape her. He pulls down her pants. She is fighting back, but given her size ,she is not a challenge for him. But then she starts a loud piercing scream. He knew he must silence her. He has her on the ground, and his adrenaline and testosterone is flowing, and in his unstable fashion, he begins to pulverize her with the rock, he get carried away.
7. Later, Z moves the body away from his territory. Another scavenger comes upon the body and decides to remove the jewelry. He takes off her earrings and then looks for a wallet. He finds her driver's license and realizes she is the one that everyone is searching for. He drops the earrings and the license. He wants nothing to do with her, but now his fingerprints are on her.
8. Z flees to his homeland. While on the run, he sells her ipad and phone, which he took from her. In part for the value, but also because her last photos were of him. When he sells them, he asks for everything to be erased, which the buyer does, and it entails turning on the devices.
And that's the way I think it went down.
