I am utterly baffled that this appears to be Z's first serious crime. Men who prey on women do not develop this habit at the age of 50 years old. Either the motivation for committing the crime had nothing to do with SS' being a woman and had nothing to do with sex, or he has done this many times in the past, and simply hadn't been caught yet. His being a habitual offender makes no sense though, because he was too sloppy in the commission of this crime. No way has he done this- at least not with this M.O.- multiple times in the past. He'd have been caught before now.
It is very likely that the person who committed this crime has killed before. These types of criminals depend on chance, there is nothing sloppy or expert about their motives.
Some killers/criminals are hard to catch due exactly to their disorganization.
And lets just speculate that Ziya is some kind of predator. With the little we know about his way of life, he would be at an advantage.
His environment would provide him with all the things he needs. What need would there be to carry a weapon when you can easily pluck out a brick from your own wall? Or a rock resting at your front door. You have any unseen hidden spot to hide if you ever need to make yourself vanish.
And the fact that Ziya had no permanent address probably helped him go undetected for so long. His trail would be haphazard, a nightmare for those attempting to track him.
And its interesting that most killers are almost always caught after they slip up. Maybe this crime was Ziyas downfall as a criminal because he drew so much attention to himself.
Articles written by Turkish women have been posted on this thread stating that, had Sarai been one of their own, the amount of resources to catch the perp would prove insufficient.
But I somehow believe Sarais being a woman had little to do with her death.
A man is much more than the worst thing he has ever done.
Good people do bad things all the time, and vis versa. Ziyas age is irrelevant. Age meant nothing when so many other serial killers or criminals were apprehended in their later years.
Thats what happens sometimes when cold cases are solved.
If he is completely innocent and the cloud of suspicion has unfairly hovered over him, I will be surprised.
Im almost 100% convinced he had some involvement.
