In the case-solving group!
Guan Hongyu: "In addition to deliberately leaving behind the murder weapon, the knife and the bronze medal, this is also a marking act.
The superficial injuries on Xu Liting and Zhao Xinkai are probably acts of intimidation in the context of criminal behavior psychology!
Tying Xu Liting to a chair should be considered as restraint."
Guan Hongfeng (brother): “That’s right!
Any behavior by which a murderer forces others to submit through physical violence, injury, psychological manipulation, intimidation, etc. can be classified as coercive behavior.
The murderer's purpose seems to be more than just killing people.
If the murderer simply wanted to kill people, judging from the traces at the scene, he had an absolute advantage and could easily kill both of them.
But the murderer has more restraint and coercion..."
Forensic pathologist Qin Ming said: "Usually when robbers break into a house and control the homeowner to inquire about the location of valuables, they will use restraint and intimidation.
But the crime scene in this case was in a hotel.
Moreover, Xu Liting and Zhao Xinkai were in two different hotels.
The criminals used coercion to get the two people's bank card passwords or transfer passwords?"
That is possible!
Shen Ting thought about it and used [Information Sharing] to obtain the communication, chat, transfer records and other information of the seven people involved in the case.
"It's so easy to investigate a new case!"
The communication and chat records alone are of great value and can provide a wealth of information about the deceased's social circle.
Unlike Li Xiangyun and Geng Qingqing last time, they had been dead for too long and their numbers had long been cancelled due to unpaid bills.
When the balance of the mobile phone account reaches zero and there is no communication for 90 days, the number will be revoked.
Even if you suspend your service to keep your number and pay the preservation fee, you can only keep it for six months at most.
In a case like this, communication, text message and other records naturally cannot be checked.
Shen Ting uploaded the information to the case-solving group and quickly checked it himself.
"The killer's restraint and coercion were intended to obtain the password for transferring or withdrawing funds, which should not be established."
Because from the time the two victims died until now, there is no transfer record on WeChat, Alipay, or bank cards.
"If you're seeking wealth, the normal procedure is to ask for the password and then transfer the money immediately.
At the very least, the transfer should be completed before the explosion occurs.
Otherwise, you will easily attract attention, which will shorten your escape time."
Conan: "If it's not about money, then what's the purpose of the intimidation?
Xu Liting and Zhao Xinkai, what secrets do the murderer need?
Also, I saw the 'kidnapper' use Xu Tuanjie's cell phone to send a text message to Xu Chanjuan at 11:12 last night.
Is it possible that the murderer learned the secret he wanted from Xu Liting and Zhao Xinkai?
To keep this secret private, I pretended to kidnap Xu Tuanjie, got the four members of his family into the car, and arrested them all in one fell swoop.
Shen Ting: “It’s possible.
If the murderer made a sudden decision to kill Xu Chanjuan and the other three.
That should be after killing Xu Liting last night, he went downstairs of Xu's house and installed the bomb in the car.
Retrieving the dashcam video from this period might help us find the murderer."
While leaving a message, Shen Ting shared the dashcam data of the exploded car.
The data from the dashcam of the exploded car will be uploaded to the cloud.
So even if the recorder was severely damaged in the explosion, there would still be about seven days of data retained.
Shen Ting continued to leave a message: “In addition to the dashcam data, it can be used as a direction for investigation.
No matter what the murderer wanted to get from Xu Liting and Zhao Xinkai, it might be involved in the couple's daily communication.
Everyone can focus on checking the chat records between the two people."
Detective Chinatown Qin Feng: "Based on the extracted mobile phone data of Xu Liting and Zhao Xinkai.
At 7:21 PM last night, Xu Tuanjie called Zhao Xinkai on his cell phone and asked him to go to Room 208 of the Shangxin Hotel.
At 20:55, Zhao Xinkai sent a WeChat message to Xu Liting, asking her to deliver the clothes to Room 434 of Changshu Hotel across the street.
Since Xu Liting also showed signs of intimidation later on.
The murderer probably didn't get anything out of Zhao Xinkai's mouth.
If Zhao Xinkai knew the so-called secret, it would be unlikely that he would not tell it.
So, he probably didn't know.
After killing Xu Liting, the murderer did not stop and killed four other members of the Xu family: Xu Chanjuan, Xu Tu, Li Xiaoying, and Guo Honggang.
The murderer may have learned this secret from Xu Liting.
This secret is probably only known by Xu's family members.
Therefore, if we focus on checking the Xu family's chat records, the chances of finding this secret will be higher."
Makes sense!
There are two directions for investigation now:
One of them!
Check the dashcam data from 9 to 11 last night.
Try to find the killer's figure.
Secondly!
Focus on investigating the chat records of Xu's family and try to find out what information the murderer wanted to obtain through coercion.
“Actually, there is another idea.
The murder weapon, the dagger, and the eye and hand elements in the bronze medal are too conspicuous.
This case is probably not the work of an ordinary murderer.
This may not be the murderer's first crime, or it may involve a gang."
In this regard, it might be better to leave it to the Investigation Bureau for investigation.
As Shen Ting was thinking, the car arrived at the Miyun Investigation Bureau.
The group got off the car in the parking lot.
As soon as my feet touched the ground, a police inspector with gray hair and a rank of two bars and three flowers came out from the hall with several police officers.
"Xiao Xiong, Xiao Xu, long time no see.
This must be Shen Ting, Consultant Shen!
So young!
It is true that heroes emerge from youth!
