Chapter 966 - 902: The Direction of the Clue
All four bodies were exposed outdoors, hence various depths of footprints and traces were left around the crime scenes. Those included footprints from suspects and the killer, and theoretically, traces from the act of rape or even necrophilia.
However, due to decay of the bodies, the exceptionally rapid growth of local vegetation, along with frequent heavy rain and sun exposure, these traces were significantly disrupted.
By examining just the footprints collected from the four cases, we can roughly determine that only the killer and the victim were present at the crime scenes. But trying to obtain more leads from this positive analysis proves to be quite difficult.
Conversely, having some analytical conclusions, using these traces for substantiation is indeed sufficient.
After reviewing the autopsy videos of three of the bodies, Jiang Yuan confidently stated, "These two bodies also bear traces of necrophilia."
"Was only the first body not raped post-mortem?" Ni Cha pondered, saying, "Was it because the first time he didn’t have such strong urges? Or was he unaware of his own needs? Or perhaps his psychology gradually became more perverse?"
Dama, once a British Colony, adopted its police configuration, training, and case-solving tactics from the United Kingdom, localized for home use. Hence, when facing a serial killer, Ni Cha’s first thought was to conduct a criminal psychological analysis.
Jiang Yuan didn’t contemplate in the killer’s mindset but simply looked up and said, "The first body was more severely decomposed; it’s hard to confirm whether necrophilia was involved. Additionally, it may have been an unsuccessful attempt at necrophilia, which wouldn’t be reflected on the body."
Ni Cha had a sudden realization: "Right, maybe the first attempt at necrophilia lacked proficiency, and perhaps penetration was unsuccessful."
"It’s also possible that he was too excited and ejaculated prematurely. If he wiped off and left the body outside for a few days, you wouldn’t be able to tell from the external tissues," Jacob suggested another view.
