The land temple in Guojiadian is currently the only place directly related to the murderer and where the bodies involved have not disappeared.
The hair and fingerprints found previously were just evidence on Zhou Xiaoxiao.
There may be other more hidden clues left in the land temple.
Chen Ting immediately contacted the physical evidence identification office and asked them to put more effort into carefully identifying all the physical evidence collected from the land temple.
However, by coincidence, just as Shen Ting finished giving his instructions, the appraiser who answered the phone hurriedly said:
"Hey, Team Leader Shen, how did you know we would find it in the samples collected at the Land Temple?"
Is there really a discovery?
Shen Ting was surprised:
"What's the specific situation? Tell me quickly."
“Team Leader Shen, this is it.
Just now, a young appraiser found multiple shoe prints in the mezzanine while inspecting the cement blocks of the base of the land temple.
It is now preliminarily determined that the shoe prints came from the same person."
After all, Chen Ting had previously acquired the skill of analyzing trace evidence, so he naturally knew the principles of identifying the residual footprints in the cement interlayer.
When workers start construction after lunch or the next day, the upper and lower layers of cement poured will not be completely bonded.
Because the setting shrinkage rates of different batches of cement are different, natural separation surfaces will be formed between them.
Therefore, if there are fingerprints or footprints left on the lower layer of cement, covering them with the upper layer of cement is not a destruction but a protection of the evidence.
Forensic examiners can first use X-ray imaging or computed tomography to "see through" the cement and confirm the location, depth, shape, etc. of the shoe prints.
Afterwards, use small precision tools to accurately remove the upper layer of cement.
Finally, of course, the shoe prints are extracted and molded.
The shoe prints obtained in this way are usually very effective in solving cases.
but……
Shen Ting suppressed the excitement in his heart and asked:
“How can you be sure that the shoe prints in the cement layer belong to the murderer?
Rather than being left behind by the villagers who built the land temple at that time?"
“This is simple. One is that the cement is not yet dry, and workers usually don’t step on it.
The key point is that, judging from the characteristics of the shoe prints, they should have been stepped on at the end of the plastic stage of the cement.
That is, two or three hours after pouring, it has reached a certain hardness, but pressing the cement will leave a slight depression.
If the workers have been working continuously, the interval between the upper and lower layers of cement should not be so long.
So our identification team speculates that the workers stopped work to rest at night, and when the murderer opened the cement layer to dig a hole to bury the body, he accidentally left shoe prints on the plastic cement at the edge!
Makes sense!
Chen Ting opened the police communication system and immediately checked the shoe prints made from the mold, frowning slightly.
These footprints don't seem to come from Qi Shengzhi! ?
Seeing this, Sun Dehua next to him hurriedly asked:
“Team Leader Shen, judging from your appearance, do you have any new discoveries?”
Shen Ting shook his head:
“It’s hard to say.
Looking at the shoe prints, I feel that they are somewhat similar to the person Wang Fuzhong met in Shizhong Town.
But I’m not sure.”
Anthropometry naturally includes the identification and analysis of foot features.
To a certain extent, shoe prints can also reflect the shape of the sole pattern and the degree of wear.
In particular, based on the depth of the lines, it can distinguish the target's pressure distribution, foot shape, and walking habits when walking.
Even if you are a master of footprint analysis, you can analyze the target's gait characteristics through a few footprints.
However, the images Kiko found were only partial and contained very little information about the features of the feet.
After all, anthropometry is not dactylology, and our knowledge about footprints is certainly not as comprehensive as the latter.
“However, one thing is certain.
The shoe prints in the land temple did not come from Qi Shengzhi.
The shoe sizes between the two differ by almost two sizes.”
"Isn't it Qi Shengzhi?"
Sun Dehua's face wrinkled when he heard this:
“That’s a bit strange!
Doesn't this mean that the murderer who killed Zhou Xiaoxiao in Guojiadian and buried her body in the Earth God Temple was someone else?"
Previously, based on Qi Shengzhi's fingerprints and hair on Zhou Xiaoxiao's body, it was judged that Qi Shengzhi was the one who killed her.
The shoe prints should naturally have been left by him.
But now, the shoe prints don’t match?
The key point is that the person who killed Zhou Xiaoxiao, Wang Fuzhong, and the deceased in the mining factory area should be the same murderer.
Doesn’t that mean that the person who killed Wang Fuzhong and the other deceased might not be Qi Shengzhi?
"Could it be that Qi Shengzhi has other helpers?
This rare earth resale involves more than four people?"
Shen Ting shook his head, a little unsure: “Well, it’s hard to say!
In theory, when it comes to illegal activities like reselling rare earths, the fewer people involved, the better.
But judging by the current circumstances of the case, if there is no fourth person involved, the case is difficult to explain.”
Shen Ting thought for a moment:
"By the way, are there any other clues pointing to Qi Shengzhi in the land temple?"
