"Team Su," on the way back to the detachment, Qi Yuan finally couldn't help but ask, "How are you sure that Zhao Ruiqing's boyfriend is also Duan Kun's lover?" ”

"Huh? I'm sure of what's OK. Su Ping glanced at him and said, "I'm just asking, how did the suspect get mixed up with Duan Kun, it's just that you made up your own brains to become his lover." ”

"Huh?" Qi Yuan opened his mouth.

"Of course, I did have this idea, but for the sake of safety, I didn't ask directly." Su Ping shrugged his shoulders and said, "You have also read the investigation report, and you know that Zhao Ruiqing is a broadcasting professional, and besides, she is also the one who pretends to be Duan Kun to chat with you, right?" ”

"I see." Qi Yuan smiled bitterly: "I have also thought about this question. She has the ability to imitate what others say, but she always needs a reference. And she and Duan Kun are not familiar with each other, so ......"

After a pause, he asked again: "But, how can you be sure that the one who is close to Duan Kun is her boyfriend?" In case she ...... someone else."

"I'm not sure." Su Ping repeated: "Guess right, everything is fine." If you guessed wrong, it's a big deal to give up this line. Even without her cooperation, it doesn't mean that the case can't be solved. ”

Qi Yuan was dumbfounded and complained, "Is it so casual? Although without her cooperation, it stands to reason that the case can be solved, but it must take a lot of effort......"

"That's right, so you can't guess without any evidence." Su Ping glanced at her and said, "Do you still remember the words she said when she was emotional after I drew out the pressure in her heart?"

She owes a lot of money and walks into the abyss step by step, although the story is not too clear at the time, but it can be easily inferred that every time she tries to resist, she finally chooses to compromise.

Moreover, she was reluctant to leave Bian Chengfeng, because she subconsciously believed that although Bian Chengfeng was pitted, all he wanted was money, and if he found someone else, he might lose everything.

Of course, this possibility is indeed not ruled out. But her performance also shows that she is a very cowardly person by nature, unwilling to change, and accustomed to compromise. Her tragedy was also caused by this compromise. ”

After a pause, he sighed lightly, and then said: "With a character like hers, it is unlikely that she will take the initiative to raise the idea of killing, and others must mention it." Previous investigations have also shown that she also has accomplices.

It just so happens that her boyfriend is also an addict, and in order to obtain drug money, he finds a way to take her into the pit and use this method to tie her firmly to himself.

It is conceivable that this man's conscience has been completely fed to the dog, and if there is a need, he may really have the idea of killing. In this case, it is safe to speculate that her boyfriend was also involved in this case.

In fact, I think you must have guessed that too, right? In my opinion, as long as there is a possibility, and the probability is relatively high, it is enough to gamble, and you don't have to wait until you are completely sure. ”

Qi Yuan silently wrote down these words.

After a while, he asked again: "Team Su, there is one more question. Sister Chai found several hairs with hair nozzles at the scene, and due to the effect of blood tension, the hair strands floated on the blood, which was presumed to have fallen when the murderer committed the crime.

The hair follicle was identified by the genetics laboratory, and DNA was obtained, and the suspect's DNA matched Duan Kun quite well, indicating that the suspect and Duan Kun may have a relatively shallow blood relationship.

This evidence should point to Dai Hong. Of course, since Dai Hong did not have the conditions to commit the crime, the suspicion was naturally ruled out.

Ke Bian Chengfeng...... What's wrong with him, he can't be related to the victim, right? ”

"I've read that report too." Su Ping explained: "The appraisal results are just a hint of the existence of such a possibility, and they are not accurate.

What's more, the possibility of the murderer being suspicious cannot be ruled out. Since he is Duan Kun's lover, it is not difficult to find out the relationship between Duan Kun and Dai Hong, and it is normal to want to blame Dai Hong. ”

"Then ......" Qi Yuan asked: "If it is really a false accusation, then how did he get Dai Hong's hair recently?" ”

"I don't know." Su Ping shook his head: "I'm afraid I can't draw a conclusion until I catch someone." ”

……

The police car quickly drove back to the detachment, and Su Ping took Qi Yuan straight to the technical team.

As the superior unit of the Physical Evidence, Trace Detection and Graphic Investigation Section, the technical brigade naturally also has its own office, and the scale is not small.

"Xiao Gao!" Su Ping walked to Zhang's desk and asked, "Have you checked Duan Kun's bank statements and loan records clearly?" ”

"Found it!" The technical policeman called Xiao Gao immediately handed over a report, saying: "From noon to evening yesterday, a total of five credit cards under his name were overdrawn, and the amount of cash was withdrawn to the five savings cards bound separately, with a total overdraft limit of 460,000 yuan.

In addition, there are a number of transfer records, including credit card loans, the total amount transferred is as much as 1.33 million.

From 4 p.m. to 8 p.m. yesterday, each of the five cards had several withdrawal records, and each card had withdrawn 20,000 yuan in multiple times, totaling 100,000 yuan.

I informed my colleague to retrieve the withdrawal records of the ATM and found that the person who was making the withdrawal was wearing a black short-sleeved shirt, dark blue jeans, and red and black basketball shoes.

The height is estimated to be about 1.75 meters, and his figure is well-proportioned, but unfortunately he is wearing a cap and a mask, and he can't see his face clearly. By the way, there is another point, his left hand is wrapped in a thick bandage, and it seems that he is injured. ”

"Hurt?" Qi Yuan was stunned for a moment, and hurriedly said: "Yes, Sister Chai found a set of messy shoe prints on the wall of the window on the left side of the back door of the convenience store, and it is speculated that when the murderer opened the window, he kicked the wall with his feet many times, and it is speculated that he may have suffered a hand injury." ”

Su Ping nodded lightly and snorted.

At this moment, the technical policeman on the side suddenly stood up and said excitedly: "Team Su, there is a discovery!" Just now, under Duan Kun's name, the Bank of Communications savings card with the card number 62***313 had a cash withdrawal record from an ATM at the Pinghe Street outlet in Lingyang District, and he withdrew a sum of 3,000 yuan...... Oh, another one! Or three thousand! ”

"Immediately notify the colleagues of the criminal investigation squadron of the police station near the outlet to intercept it!" Su Ping hurriedly ordered, and at the same time immediately grabbed the walkie-talkie, adjusted the frequency, and called: "Criminal Investigation Detachment, Su Ping, call the command center!" ”

"Command center received! Team Su, please. The other end of the intercom replied quickly.

"At present, Bian Chengfeng, a suspect in the homicide case, is withdrawing cash at the branch of Pinghe Street, Lingyang District, Bank of Communications, and our detachment has sent someone to intercept it.

However, in order to prevent the suspect from escaping, the Lingyang Branch was requested to cooperate to block the nearby traffic arteries and provide the nearby traffic monitoring probe video in real time, over! ”

"Received, the application is now transmitted to the Lingyang Branch."

After putting down the walkie-talkie, he glanced at Qi Yuan and said, "Trainee, let's go, let's go over and have a look!" ”
