September 5, 2020, 10:30 a.m.

The atmosphere in the No. 1 conference room was silent and depressing, Sun Baoqiang and the others smoked cigarettes silently, and their brows were furrowed.

Chen Jianbin has never encountered such a difficult case, and every clue seems to be non-existent, either without a clear point, or the chase is interrupted at a normal time.

Wang Tao just reported the origin of the package equipped with a strong magnetic field timing device, and unlike the threatening letter, this package was not mailed by the murderer with help.

According to the recollection of the Shentong Express courier, all the express packages that day were loaded at the station at 6 o'clock in the morning and then delivered.

According to the workflow of the courier company, all shipments that need to be delivered will be scanned and sorted the day before, carried out by a dedicated sorter, and the next day the delivery person will load the parcel directly at the delivery station for delivery.

"We checked all the packages delivered to the detachment on the day of Shentong Express, a total of five, all of which have been scanned and registered, and can find out all the information of the mailer, recipient and so on."

"But the camouflaged package is not in the range of five, but the sixth package, and the delivery code on it is indeed Zhang Lijun's, but it is the package delivery code he received five days ago."

Chen Jianbin looked at Zhang Lijun, and the other party spread his hands helplessly: "I bought an electric shaver online, and after dismantling it, I threw the outer packaging of the package into the trash." ”

Wang Tao has checked the whole process very clearly: "The other party forged a new package through the outer packaging of the package that Lijun threw in the trash, and mixed the package into the delivery vehicle during the delivery of the courier. ”

Operation projection, above which are three pictures: "Before the courier came to the detachment, he also went to three places: the Merrill Lynch community, the grain bureau and the water company. ”

"Among them, the food bureau and the water company are monitored at the gate, and we have sent someone to transfer the video of the delivery man during the delivery on the morning of the third day, and the delivery vehicle has been monitored during the whole process, and there is no abnormality."

"However, there is no monitoring around the delivery location in the Merrill Lynch community, and the murderer should have mixed the package into the delivery vehicle at this time."

In the photo, it is the gate of the Meilin community, this place is very clear to everyone, about a kilometer behind the criminal investigation detachment, it is the largest community nearby, built 20 years ago, the infrastructure is relatively old, the flow of people is large, and there is basically no monitoring equipment.

After listening to the report, Chen Jianbin tapped his index finger on the table, making a regular impact sound, and the clues of the two cases have all been investigated, and nearly 30 hours have passed since the two were killed.

The golden time for solving the 72-hour murder case is getting closer and closer, and Chen Jianbin can imagine the pressure.

"First," Chen Siliang sighed lightly and glanced at everyone: "The key investigation plan for Zhao Guangming's murder case has been shifted to the tracking of accessories for strong magnetic field devices. ”

"The opponent is very cautious and cautious, and is good at taking advantage of our loopholes, in the threat letter, mobile phone text messages and even package delivery, there is no show of any horses, and the use of a strong magnetic field timing device to kill Zhao Guangming is something we did not expect."

Chen Jianbin paused and looked at Wang Tao: "But from the analysis of the technical room, the device is self-made, although many parts are common electronic components, the purchase channel is very wide, but the other party needs to buy a small amount, but there are many categories, so many components can not be obtained in a store, so step up the city's electronic components market to find out." ”

Chen Jianbin 's tone gradually became stern, and the sharpness in his eyes was also full, and the decisive and resolute criminal investigation team leader returned: "But I don't believe that the other party can leave no traces at all, you have to check the surveillance video of all relevant places, compare the suspect characteristics analysis we did in advance, and catch the other party's little tail!" ”

"Team Chen, don't worry, I'll arrange it, even if I dig the entire Tengfei Mansion three feet into the ground, I will find this bastard!"

Wang Tao is also holding his breath, he has been a police officer for so many years, Wang Tao has no unsolved cases in his hands, and it is normal for him not to catch the suspect, but he has never been so aggrieved in the past two days, and he can only be led by the nose by the other party.

"Second," Chen Jianbin glanced at everyone: "Regarding Lao Sun's case, I personally led the team to investigate!" ”

Everyone has obviously guessed Chen Jianbin 's plan, a criminal policeman was killed, it can be said that a nuclear bomb was dropped on the Public Security Bureau of A City, Chen Jianbin as the head of the criminal investigation detachment must personally go into battle: "Two aspects of work to advance, the first is to check Lao Sun's nearest contacts, especially if anyone has contacted Lao Sun throughout the day, you will be responsible for Xia Dong." ”

"Yes, we have started investigating Officer Sun's communication records, and the results will be available soon."

Chen Jianbin nodded, Xia Dong can become the head of the technical office of the criminal investigation detachment at the age of thirty as a woman, and his ability is beyond doubt.

"Second, we have to check the old grandson...... How was the investigation of the 718 fire back then, who did he contact recently, and whether there were any special circumstances, Baoqiang, you are responsible for this. ”

Although Sun Haining has not worked on the front line because of his disability over the years, he has never given up investigating the case of the fire that year.

The old men of the criminal investigation detachment are very clear that Song Chuan also understood the rights and wrongs here after Sun Baoqiang's explanation yesterday.

watched his own sister and nephew die in the fire, but he didn't have the ability to rescue him, and no one would give up.

After the meeting, Chen Jianbin went to the municipal bureau again to report.

Song Chuan was dragged into the office by Qin Feifei, and he couldn't help but look sideways when he saw the colleagues around him.

"Senior sister, I'm still single, you dragged me into the house in front of everyone like this, isn't it?"

Qin Feifei rolled her cute big eyes: "It's all dragged in, don't you want to taste Senior Sister's seafood?" ”

Song Chuan almost fell under a certain woman's pomegranate skirt: "Senior sister, I am allergic to seafood and never eat abalone......"

"You still want to eat? Licking can also quench cravings! ”

Song Chuan: "......"

Big sister, I beg you to stop talking, my face is crushed under your wheels.

Too lazy to pay attention to Qin Feifei, who was racing cars, Song Chuan opened the refrigerator and took out a popsicle: "I'll lick this, do you want one?" ”

As a result, someone Qin stretched out his little finger and waved at Song Chuan, got it, understood, he still disliked the popsicle being too thin......

Qin Feifei, who was sitting in front of the computer, flashed super red with excitement on her face, and pulled Song Chuan's arm beside her: "Little junior brother, come and see what good things I found." ”

Song Chuan, who was eating popsicles, was stunned, he didn't know what good things Qin Feifei had found, but he knew what good things he felt, but the fathead fish was material, but is there a problem with our name.

"Qin Da Beauty, junior brother is junior brother, why add a small word?"

"Don't care about these details, show you this!"
