Miyun District Public Security Bureau!
Case Study Office!
When Shen Ting heard Qian Duoduo's question, he smiled and said:
“There are several directions for investigation.
Ahem~~"
Not yes, but how many?
The police officers perked up instantly and all looked at Shen Ting.
Qian Duoduo noticed that Shen Ting was coughing due to the smoke and ordered everyone to put out the cigarettes.
Shen Ting continued:
“Let me first talk about the less urgent areas of investigation.
The explosives used by the murderer are similar in composition to detonators, and the amount used is very large.
In addition, the murderer perfectly avoided surveillance inside and outside the two hotels, leaving only his back.
I have two doubts:
The murderer lived near the hotel and worked on a construction site, and the detonator came from the construction site.
Or, the murderer is a professional killer!
The former is easier to check. Just go to the construction site near the hotel and investigate whether the number of detonators has decreased.
As for the latter, it probably involves the criminal organization behind the dagger and the bronze medal.
Captain Qian, you can urge the General Administration to provide the information as soon as possible."
"Next is Xu Tuanjie!
His disappearance was very strange. Through the last call the criminal made to him, I could roughly determine his location when the murderer contacted him.
I'm in charge of this area. I'll search the suspected locations and try to find Xu Tuanjie."
"The final direction is Zhang Haisheng!
I used some means to confirm that the owner of the last mobile phone that called Xu Tuanjie before he disappeared was named Zhang Haisheng, and he was from Dajing.
This is his current contact information and address.
Go and bring him back and intensify the interrogation."
Listening to Shen Ting's analysis, the police officers felt that it was nothing at first.
Investigating criminal organizations and searching for Xu Tuanjie are both relatively easy to think of investigation directions.
Checking the construction site near the hotel to see if there were any detonators missing gave the police officers some new ideas.
The police officers were greatly surprised by Zhang Haisheng, who was pointed out by Shen Ting at the end.
"Zhang Haisheng?"
"He was the one who contacted Xu Tuanjie in the end?"
"There doesn't seem to be any such person in the case files, especially in the Xu family's social circle!"
“Brother Shen, how did you confirm this Zhang Haisheng?”
…
"Through the IMEI number of the phone itself.
Through some means, I obtained the IMEI code of the mobile phone used by the murderer when making the call.
Then we tracked down Zhang Haisheng!"
Shen Ting explained simply.
The surprise on the police officers' faces was even more obvious.
Get the IMEI of the dialer's phone through call records!
Then confirm the owner of the phone through IMEI?
Although Shen Ting downplayed these two steps, they sounded very complicated!
Computer technology is definitely required, and it must be very sophisticated computer technology.
Consultant Shen is so proficient in computers?
The members of the Internet Investigation Team were particularly shocked and looked at Shen Ting in disbelief.
In the conference room, they were the only ones who knew how difficult what Shen Ting said was.
According to their past experience, just the first step, confirming the IMEI of the caller's phone, would be impossible to accomplish within ten days or so.
Because you need to apply for corresponding data from the telecommunications company.
The data of base stations is massive.
It takes a long time to decipher and determine the IMEI code, whether with the help of the telecommunications company or the cyber investigation team themselves.
But Shen Ting, was it confirmed so quickly?
You know, not even a day has passed since the car exploded.
Shen Ting only had half a day to get involved in this case.
This efficiency is terrifying!
Qian Duoduo was also surprised, but he also knew that Chen Ting might have used some unspoken means, so he coughed dryly:
“Next, we will investigate as Consultant Shen said.
You split into three teams. One team will follow Shen Ting and try to find Xu Tuanjie.
A team went to the construction site near the hotel to investigate the detonators!
There is another team to capture Zhang Haisheng!
As for me, I will contact the Dajing Investigation Headquarters and ask them to provide information about the criminal organization as soon as possible.
in addition!
I would also like to urge the investigation into Xu Tuanjie's mistress, car surveillance, wireless signals, etc.
If there are no more questions, the meeting is over!"
