Chuanshan

While waiting for coffee, Yan Lan looked at Su Xing and said, "Speak up if you have something to say."

Su Xing: "I am... Captain Yan, I didn't do it on purpose."

"what?"

"Well... I'm just talking casually, this house type is pretty good..."

Yan Lan sat casually on the high chair next to Nakajima and said, "Hey, what did I think, it's okay, this house type is really weird, and you're right."

Seeing that Yan Lan really didn't care, Su Xing breathed a sigh of relief.

Yan Lan said: "Everyone in the team has been to my house, so don't be nervous, just come a few more times. I was really sleepy just now, otherwise I would have driven back by myself."

Su Xing nodded.

Yan Lan took a cup of coffee, pushed it in front of Su Xing and said, "The sugar is on your left, and the milk is in the refrigerator."

Su Xing: "Thank you Captain Yan, I won't add anything."

Yan Lan took another cup for herself, and said, "As I get older, I'll be sleepy after a night."

Su Xing smiled and said, "You don't look old, Captain Yan."

"It's just that you don't look old." Yan Lan took a sip of coffee, "Once you pass thirty, your mentality and body will be different. You are really young, and I am pretending to be young."

Su Xing didn't speak any more, and Yan Lan didn't care, the two just sat and drank coffee facing each other.

When Su Xing pulled his clothes for the fourth time, Yan Lan finally said, "My stool is uncomfortable?"

Su Xing waved his hands again and again: "It's not Captain Yan, don't get me wrong, the label on the back of my clothes is tied."

Yan Lan took out a pair of small scissors from the side and said, "I cut it for you."

"I'll do it myself."

"Do you have eyes in the back or are you going to be naked in front of me?"

Su Xing was stunned for a moment, then lowered his head and said, "Thank you Captain Yan."

Yan Lan held up the scissors and walked behind Su Xing: "Don't move, I'm not responsible for stabbing you."

Su Xing gave an "um" and sat down on the chair obediently.Through his clothes, Su Xing could feel the warmth of Yan Lan's hands, as well as his faint breathing.In fact, the back of Su Xing's neck is very sensitive. The moment Yan Lan touched him, he had goosebumps all over his body, but because of what Yan Lan said, he froze in place and did not dare to move.

After about 5 minutes, Yan Lan patted Su Xing and said, "Okay, relax, don't be tense."

Su Xing let out a long breath, and thanked Yan Lan again.

Yan Lan said, "Your neck is a little red, if you feel uncomfortable, apply some moisturizer."

Su Xing raised his hand and touched the position, but was stunned as if he suddenly remembered something.

Yan Lan asked, "What's wrong?"

Su Xing withdrew his hand and said, "Captain Yan, can you take a picture of my back for me? I seem to know what the marks on the backs of the three corpses are!"

"Take your mobile phone to take pictures." Yan Lan took Su Xing's mobile phone and walked behind him to take a few photos, then returned the mobile phone to him, "Take a look."

Su Xing grabbed the phone and took a closer look. He wanted to continue to look through the photos of the dead body in the album, but found that the phone was actually locked all the time. Just now, Yan Lan used the lock screen quick photo mode.Su Xing unlocked it immediately, but regretted it the moment he swiped open the phone, and hurriedly closed the current page——Yan Yao's encyclopedia entry.

Just now when Yan Lan came downstairs suddenly, Su Xing locked the screen directly in a panic, but at this time Yan Lan was standing beside him, seeing his phone screen directly.It was so embarrassing!After secretly checking the leader's life experience and being caught by the leader, Su Xing even felt that he heard Yan Lan's faint chuckle.

"What do you see in the photo?" Yan Lan's tone was not as soft as when he was chatting just now, and it became the state of work again.

Su Xing quickly called up the previous photos of the corpses and compared them.Yan Lan let out a "tsk", turned her head away, and said, "You are really Mr. Wang's apprentice, and the phone albums of you two are unacceptable to ordinary people."

Su Xing didn't answer, just compared several photos back and forth, and said after a long time: "Team Yan, these three corpses C6 to C7, oh, there are slight scratches on the skin near the sixth and seventh cervical vertebrae. I didn't know how at first, but now it looks like it was worn down by a clothing label or something like that."

Yan Lan put the trademark that was cut out just now in Su Xing's hand: "Go back later and do a comparative experiment."

Su Xing nodded and asked, "Then shall we go back now?"

Yan Lan pointed to the cup and said, "Drink the coffee before going back."

"Oh..." Su Xing put away the trademark and picked up the coffee again, he was a little afraid to look at Yan Lan now.

Yan Lan didn't go back to the other side of the island, but just pulled away the chair beside Su Xing and sat down, saying, "Yan Yao is my uncle."

"Ok?"

"Aren't you looking for him?" Yan Lan pointed at Su Xing's cell phone with her slender fingers, "He's my uncle, I have my mother's surname."

"Sorry, I'm not..."

Yan Lan said: "It's okay. I'm right in front of you right now. If you want to know anything, just ask. I know more than Baidu."

Su Xing took a sip of his coffee, then shook his head and said, "I really don't want to spy on the leader's privacy. I'm just curious... This house must be very expensive."

Yan Lan: "The unit price is not expensive, one hundred thousand and one square meter at the opening. But each building has more than two hundred square meters, so the whole set is not cheap. Of course I don't need to spend money, this is what he left for me. This house It used to be a model room. I didn't change the layout or anything, so I just lived in it. Only he can make the wonderful house type with six bedrooms, six bathrooms and three living rooms. But Qiao Chen and the others like it very much, so you don't have to worry about snatching it up when you come to my place for a party bathroom."

"Really rich." Su Xing sighed sincerely.

Yan Lan finished drinking the coffee in the cup, and said flatly: "It's useless to have money, I can't get back what I want."

Su Xing raised his head and looked at Yan Lan, who said with normal expression, "Let's go, go back to the team."

Su Xing: "I'll wipe the glass before leaving."

Yan Lan stretched out his hand and stuffed the two cups into the dishwasher: "Technology is used to free your hands."

Su Xing followed Yan Lan to the garage, and Yan Lan said, "It happens that you are here, so I will drive my own car."

Su Xing heaved a sigh of relief, if Yan Lan took the same car with him again, he would be so embarrassed that he didn't know what to say.

As soon as he got back to the police station, Su Xing rushed into the forensic room, while Yan Lan took Qiao Chen to the Western District Bureau.In the afternoon, people from the detachment gathered in the meeting room for an analysis meeting.

Lin Huan put the computer on the big screen and said: "I went through all the call and chat records of the three deceased, and found three suspicious chat records. The first one was with Duan Zhuo, called "Chunzhi" ", this person may be the last person Duan Zhuo saw. Judging from the chat records, Duan Zhuo and her are in a relationship. The second WeChat account is "π", which is the symbol of pi. She claims to be a student preparing for the postgraduate entrance examination , the chat record with Luo Pingwen has changed from asking questions at the beginning to flirting. And the one who talked a lot with Zhang Mingzhi recently is called "Plain". The two originally made an appointment on the 18th, which is the day Zhang Mingzhi died. Yes, judging from the content, the two of you should have seen it."

Yan Lan asked after listening, "What do you think?"

"I suspect it's the same person." Lin Huan explained, "Although they don't have the same WeChat ID, it can be seen from the common language used in chat that their habits are almost the same."

Pang Guanglong asked: "What do you think?"

Lin Huan arranged the three chat records side by side on the big screen, and said: "These three chat records belong to the three deceased and three suspicious accounts. You can read each other's messages. First of all, the other party is used to using a complete narrative, that is, a The message tells the whole thing. Second, the other party likes to use punctuation marks to express. Commas, periods, commas, question marks, etc., and the use can be regarded as rigorous. Third, the other party likes to use WeChat The little yellow face emoticon that comes with it, and most of them are sent in three bursts. Fourth, the other party will correct the typo, that is, if she finds a typo, she will deliberately supplement and correct it. "

Pang Guanglong: "But these are very small habits, which can be found around us. Xiaosu and the beast like to use punctuation. Deputy Qiao will correct typos when sending messages, and Mr. Wang next door can say eight things in one message. thing……"

"cough……"

"Boss, I have no other intentions! Don't complain!"

Yan Lan ignored him and motioned for Lin Huan to continue.

Lin Huan: "Three different people happen to have these four habits, and they happen to know the three deceased, and they happen to contact them before they die, and what is the probability that they disappear at the same time after death? ?”

"All disappeared?" Pang Guanglong asked.

Lin Huan: "Not only did they disappear, but these three WeChat IDs were used to contact the three deceased. According to the information I got from the software vendor, there was only one contact person in each of the three WeChat IDs, which corresponded to the three deceased. The deceased. Moreover, none of those WeChat accounts have been logged in after the deceased's death, and the mobile phone number used for registration has also been deactivated."

"Then there should be a position, right?" Qiao Chen asked.

Lin Huan shook his head: "WeChat uses virtual positioning software, which has been handed over to the technical investigation, and there is no news yet. The mobile phone number is even more evil, and it has almost never been turned on, let alone mobile data."

Pang Guanglong frowned and asked, "Then how do you use it?"

"Mobile wifi." Lin Huan explained, "Turn on the airplane mode of the mobile phone and turn off the communication function, which almost bypasses the base station positioning and data positioning. Using mobile wifi to surf the Internet and use WeChat is equivalent to using another mobile phone number. "

Yan Lan knocked on the table and said: "Investigate again. Anyone who knows the deceased's relationship with men and women must focus on investigating the deceased's relationship, expand the network, and find intersections. If the murderer is really alone, Then there must be intersections in the social network of the deceased."

Liu Yi pushed the door open and entered, and said, "Pingqiu District! All present!"

"..."

"Depend on!"

"Again?!"

Three minutes later, three police cars ran towards Pingqiu District with their sirens on.

Pingqiu District is a well-known commercial district in Pinglu City. Almost all companies with a slight reputation have office buildings there, and several large companies directly set up their headquarters in Pingqiu District.On the afternoon of a weekday, the floating corpse was found in a crowded commercial area. This was a blatant provocation to the police, and everyone in the detachment was left with a headache.

The body was found in the fountain pool of the circular square in the middle of the four office buildings. The cordon was already full of onlookers at this time, and several nearby TV stations and Internet media were dispatched after hearing the news. The scene was once very chaotic. .

"This is the fourth floating corpse found in this city within a week. The police have not issued any statement on this serial case..."

"The floating corpse case that shocked the city has added another victim..."

"Hello, viewers, welcome to Pingshi Burst. Now we are in Pingqiu District..."

"...we see that the police are now on the scene..."

Yan Lan looked at the reporters and onlookers outside the cordon in the distance, turned her head and said, "Deputy Director Liu, thank you for your hard work."

After speaking, he took the team members out of the car.

"You...!" Liu Yi cursed in his heart, then quickly adjusted his police uniform and cap, and walked to the reporter with the pace of "going to die generously".

On the other side, Su Xing and Wang Jun entered the scene for a preliminary autopsy after the trace inspection and photography work.

"Depressed skull fracture, external genitalia cut." Su Xing sighed, "Another one!"

Yan Lan asked, "When did you die?"

Su Xing: "Within 24 hours."

Wang Jun examined the corpse carefully and said, "Yan Lan, this corpse will be a breakthrough. Do you want to come and see our autopsy?"

Both Yan Lan and Su Xing looked at Wang Jun in surprise, Wang Jun smiled and said to Su Xing: "When encountering highly similar corpses and suspected victims of serial cases, the first thing to do is to get rid of preconceived ideas. Always remember that every corpse was once a living person, so every corpse will have its own uniqueness."

Su Xing nodded seriously and said, "I know Master."

Wang Jun pointed to the cut surface of the perineum of the corpse, and said, "Su Xing, take a look again."

Su Xing moved to the corpse and observed it carefully for a while, then said somewhat unconfidently: "This incision is indeed a living reaction, but it doesn't look right."

"Near-death injury." Wang Jun explained, "The mechanical injury formed when a person is near death, the wound's life reaction is very complicated, sometimes there is, sometimes not at all, near-death injury is the most difficult to identify. Su Xing you Learned well, but still lack experience, take your time."

Yan Lan interjected, "Old Wang, say something that I can understand."

Wang Jun: "To put it simply, the difference between this corpse and the previous three is the time when his genitals were cut off. The first three all had very clear life reactions, presumably about an hour before death. And this one A corpse was cut off just before death. Judging from our previous autopsy, the murderer was a very careful person and did not leave too many clues on the corpse, and this is what we have discovered so far This is the fourth corpse. You should know, Yan Lan, that this kind of serial killer will 'progress' every time. Logically speaking, it should be harder for us to find clues, but this time he made a mistake."

Yan Lan: "In other words, the deceased may help us find the murderer?"

"Maybe." Wang Jun looked at Yan Lan and said, "But you can't relax your vigilance. Once this kind of murderer realizes that he has made a mistake, he may continue to commit crimes in retaliation."

Yan Lan was about to say something, but heard the phone ringing.He took out his mobile phone and looked at it, sighed helplessly, and said, "I'll go there, you guys are busy first."

Su Xing looked in the direction Yan Lan left, and in the distance a Rolls-Royce Phantom was quietly parked by the side of the road.Su Xing raised his head and looked around, only to see the huge words "Xiyao Group" on the office building on the east side.He smiled silently, this is Yan Lan's case handling office at the door of his house.

Su Xing took a deep breath, looked around, squatted down and lowered his voice and said to Wang Jun: "Master, I feel a little uncomfortable, go to the side and relax for a while."

Wang Jun immediately raised his head and asked, "Have you brought any medicine?"

Su Xing nodded: "Take it. I'll find a place with few people to rest for a while, it's okay, don't worry."

"Go quickly!" Wang Jun said, "Take your mobile phone and call me if you need anything."

On the other side, Yan Lan walked outside the cordon, walked straight through the crowd, and walked around to the car from the other side of the square. Yan Yao's secretary was already waiting by the car, and immediately opened the door for him when he saw Yan Lan coming.

"What's the matter?" Yan Lan was not polite, and asked directly after getting in the car.

"You child, can't you talk to me well?"

Yan Lan raised her eyebrows and said, "Uncle, what are your orders?"

Yan Yao stared at Yan Lan helplessly, and said after a long while, "Forget it, I don't know who you are following with your temper."

"I grow up by myself, and no one follows. Tell me quickly, I'm very busy."

"Lanlan!"

Yan Yao felt the sting from Yan Lan, and immediately changed his address again: "Okay, Captain Yan, I will provide information to your people's police as a legal citizen, you have to accept it, right?"

Sure enough, Yan Lan softened her tone and asked, "What information?"
