"Zhang Qianqian?"
Zhuo Yan heard Chen Ting's question and said in surprise:
“It’s unlikely that she is the murderer, right?
She seemed to be less than ten years old at the time.
Even if he had a hammer, it wouldn't be possible to kill Matsumoto Kozo directly, right?!
That Matsumoto Kozai is quite tall.
Besides, Zhang Qianqian is his biological daughter after all, and there is no direct hatred between them..."
Shen Ting nodded: “Zhang Qianqian is naturally not the murderer.
I was thinking, wasn’t she the one who helped open the door before? She should be nearby now. I should find her and ask her to help lock it…”
Shen Ting suddenly stopped talking midway.
His eyes were looking straight at the door of the house.
Then Zhang Qianqian appeared there with her grandfather.
Outside the isolation zone, she also introduced the situation in the house to her grandfather.
Her grandfather Zhang Fugui, with his not-so-bright eyes, quickly scanned the situation in the room.
Judging from his expression, he seems to be thinking about something.
Then, he saw the young man standing in the middle of the house, suddenly pointing his finger at him:
"Director Zhuo, that's him!
Here, the person who attacked Matsumoto Ziqing with a hammer is Zhang Qianqian’s grandfather, Zhang Fugui.”
Bloodstain morphology analysis can reveal the murderer's physical characteristics.
For example, by throwing away bloodstains and restoring the trajectory of the murder weapon, the size of the murder weapon and the length of the murderer's arm can be determined.
Combined with the relative positions of the victim and the murderer, the parts of the body attacked, and the blank areas of bloodstains that were blocked by the murderer's body during the bloodstain splattering and splashing process, we can get the murderer's height, body shape, etc.
certainly!
Generally speaking, whether it is the wire-pulling method or software analysis, the data on the murderer's body shape obtained has a relatively large error.
Even Chen Ting is the same.
But in addition to bloodstain patterns, Chen Ting is also proficient in human body measurement.
He can use this technique to correct the body data obtained from bloodstain patterns, which has large errors.
After Shen Ting obtained some of the murderer's body data, the person he had just met not long ago appeared in his mind -
Zhang Fugui!
And now!
Hearing Shen Ting's reminder, the police officers rushed forward and controlled Zhang Fugui, who was in a state of panic.
In fact, the police officers were also in a state of shock, even Xiong Beibei, who was the first to rush out to arrest people.
If other people say that the person who killed Matsumoto Koqing was not Zhang Li or Yu Qingwei.
But it’s Zhang Fugui!
Xiong Beibei will definitely be suspicious and may hesitate for a moment before taking action to control Zhang Fugui.
But this conclusion was said by Shen Ting. Well, Shen Ting must have his reasons. Let's control it first.
Zhang Fugui was taken away, and Zhuo Yan immediately asked:
"Team Leader Shen, it was Zhang Fugui who did it back then?"
Shen Ting nodded: “Judging from the shape of the bloodstains, it is indeed him.
Later, I will compile a bloodstain morphology report, explaining in detail and analyzing the entire process of proving that Zhang Fugui is the murderer.
You guys take him back and interrogate him first.
By the way, Zhang Li’s mother might have been there that year.
It would be best to control her as well to prevent her from destroying the remaining physical evidence.
A search of their residences must also be launched immediately.
If it were just the bloodstains, Zhang Fugui might not plead guilty, and there would be a lot to argue about in court.
It would be great if we could find other evidence.”
"Okay, I'll find someone to do it right away."
Zhuo Yan wrote them down one by one and assigned the tasks to different police officers.
…
The interrogation of Zhang Fugui began soon.
As Shen Ting expected, Zhang Fugui insisted that he was wrongly accused.
However, subsequent investigations revealed some significant findings.
The Heng City police officers who went to search Zhang Fugui's residence found a pool of blood on the garage floor. After taking samples for identification, they confirmed that it came from Matsumoto Ziqing.
The task force members, led by Xu Xinyi, searched the area around the residence.
Based on his many experiences of searching for corpses with Shen Ting, Xu Xinyi felt that the river next to Zhang Fugui's residence was rather suspicious.
It might be the dumping site for the remaining bodies!
Chen Ting asked the three corpse-searching team to look at the images near the river.
The three also felt that the river might be the place where the body was dumped.
And on the map, the key search areas were circled.
Frogmen and salvage personnel quickly arrived at the scene and carried out salvage operations in the corresponding area.
Finally, at dawn when the sun just rose, a discovery was made -
The frogman salvaged a broken bone!
The forensic doctor determined that it should have come from the right tibia.
The missing parts of the victim's body found in Wanfo Cave happened to include the right tibia.
"Oh my god, did you really find it?"
"The area identified by Team Leader Shen is so accurate?"
“Why don’t we all call Team Leader Shen the King of Corpse Search?”
…
More and more corpses were salvaged from the river.
After DNA identification, it was confirmed that the broken bones and the bloodstains in the garage also came from Matsumoto Kozo.
The police officers speculated that Zhang Fugui must have taken this part of the body and wanted to dispose of it separately.
He first put the body in the garage, which resulted in the bloodstains on the ground.
They would wait until late at night, or a rainy day suitable for disposing of the body, before throwing that part of the body into the river.
With these evidences, Zhang Fugui finally confessed his guilt.
He confessed that he dismembered the body and threw each part into the river separately so that the police would not be able to confirm the identity of the victim.
He had checked the information and found that as long as the source of the corpse could not be determined, even the most skilled investigator would find it difficult to proceed.
As for the course of events, it's quite simple...
