"But that's not the case, it's all his selfishness." Speaking of this, Su Tong's mind flashed.

"Officer Xiao He, can you find out the murderer's posts every time he selects a victim? If I'm not mistaken, the number behind each of his picks is about the same. Su Tong turned his head and said to He Xingchen, who was stunned and listening.

"In other words, in fact, this website is a material library for the murderer, and he selects targets similar to his heart from it to obliterate them." Xu Sa came to a conclusion in a deep voice.

Although He Xingchen didn't quite understand what Su Tong and Xu Sa were talking about, he still followed Su Tong's words and quickly transferred the content out.

"Team Xu, really, the numbers are all about the same!" He Xingchen looked at the numbers on the screen and couldn't close his mouth in shock.

There are four numbers written after each person's name, and in the names listed by He Xingchen, the third number is exactly the same.

"Unfortunately, we still don't know what those numbers mean." Xu Sa frowned.

Everyone gained a lot tonight, only he and Su Tong found nothing, and they couldn't find out the code words hidden in the website.

Wen Yan stared at the screen for a while, then said hesitantly, "I think I might know what these numbers mean......

"Everyone knows the parity hidden in the ID number, right?" Wen Yan pointed to the last digit of the four digits and said, "In the ID number, the penultimate digit indicates gender with odd and even numbers, odd numbers are male, and even numbers are female. ”

"I guess this line of numbers means the same thing out of the four numbers."

"What about the first two?" Su Tong pointed, "Why can't the first two digits represent gender?" ”

"Because it's not convenient enough." Wen Yan shook his head, "Think about it, judging from our profile of the murderer, the other party should still keep his previous job." Then in addition to work and family, there is not much time to commit crimes, at this time, in addition to being similar to the object of hatred, there is also a very important condition for choosing a victim. ”

"Geolocation." Xu Sa hugged his arms, "He must choose a victim within his own convenient range of activities, so that even if he commits a crime, he will not be seen by his family and the people in the unit." ”

"That's right." Wen Yan nodded and gave Xu Sa an appreciative look, "According to the conditions that the murderer attaches importance to, the first two numbers cannot be the meaning of gender, but represent geographical location." ”

"Geographical location ......" Su Tong looked at the two numbers in front of him thoughtfully, and the more he looked at them, the more familiar he felt, "These numbers, how do I feel like I......'ve seen them somewhere?"

"That's right! Zip! Su Tong snapped his fingers violently, "Officer Xiao He, please ...... you"

"This is the zip code for each district in City B." Without waiting for Su Tong to finish speaking, He Xingchen pushed the computer to her, and smiled at her embarrassedly at the end.

Su Tong was stunned, turned around and said to Xu Sa with a serious face, "I think it is really necessary to add a talent like Comrade He to my group." ”

Xu Sa, "......"

"The postal code has always used the 'four-level six-code system', the first two represent the province, the third represents the postal district, the fourth represents the post and telecommunications office, and the last two digits are the number of the delivery area."

Everyone looked at Su Tong's words and found that the first two digits of the list on the other side could be matched with the last two digits of the zip code found by He Xingchen, and they were mainly concentrated in two areas.

"These two areas, all in the West End!" Zhou Li gasped, "Therefore, it is not by chance that the murderer chose that abandoned building to commit the crime!" ”

"There is never an accident in a case." Xu Sa said solemnly, "Xingchen, convert all these lists into the data that Su Tong and Wen Yan said, and then compare them with the lists they brought back." ”

In this way, the comparison can determine that those people died at the hands of murderers.

The first rays of sunlight in the east shone through the clouds, full of hope, just like the harvest of the serious crime team.

"Officer Su and Officer Wen are too powerful." Zhou Li was about to lie on the table alive, her eyes narrowed, looking at the appearance that she could sleep at any time, "Their analysis just now, I can't help but get goosebumps when I think about it now." ”

"Aren't you yelling that you're sleepy, take Officer Su and Officer Wen to the director to report the situation while you take the lead, and hurry up and sleep for a while." Li Hua yawned heavily, "I didn't work in vain all night last night." ”

Zhou Li propped herself up and leaned over a little excitedly, "Can you sleep?" Anyway, I can't sleep, just now when everyone was analyzing the murderer and what kind of code words, I should really shoot that scene for the other groups to see, it's awesome! ”

"I said, you are a girl's family, you still speak a little sven, otherwise you really can't get married." Chen Hui, who was lying on his stomach on the side, also interjected.

The last three people who couldn't sleep after being tired all night pulled over the bench and gathered together to look at He Xingchen, who had been seconded during their absence.

At first, He Xingchen could resist the urge to turn back and concentrate on his work.

But then he was really uncomfortable being stared at, so he could only turn around in embarrassment, "Senior brothers and sisters, is there something wrong?" ”

"Senior brother's name is He Xingchen, right?" Zhou Li smiled and posed as a harmless sister.

He Xingchen shrank and nodded.

"Nice boy." Li Hua stretched out his hand directly and put his hands on his shoulders, "Look at the two hands you showed just now, when will you teach the senior brother." ”

"Yes, you can ...... at any time" He Xingchen stumbled and replied.

When he was in the information group, because of his personality and his uncle's relationship, everyone was reluctant to talk to him except for the necessary work.

Suddenly being surrounded by Zhou Li and them joking like this made him a little uncomfortable, but from his heart he was happy.

"Come on, you two don't scare anyone." Chen Hui watched Li Hua and Zhou Li squeeze He Xingchen in the middle, crying and laughing, "The boss and Officer Su have said that Xingchen will definitely join our serious crime team in the future." ”

He Xingchen's eyes lit up, "Is it true!" Can I really join the Crime Squad for Serious Crimes? "Before, he thought Team Xu was joking.

"Little brother, you don't know the character of our leader." Li Hua patted He Xingchen's shoulder comfortingly, "Our leader, we can joke about everything, but there are only two things, he will never joke." ”

"One is a matter at work, and the other is ......" Speaking of this, Li Hua deliberately lengthened the tone.
