In the end, Qu Liuwan still drove the diligent old driver who didn't say a word and was just driving silently.

In fact, when the old policeman noticed Qu Liuwan looking at him, he very consciously pulled over, and then squeezed into the police car that followed behind.

Although Tang Tian has not been in this system, he has spent four years in the police academy, and he clearly knows that in this group, if you want to be respected by everyone, there are no more than two possibilities.

The first is that he has outstanding ability, so outstanding that he is far above the average of everyone, and the second is that he has a glorious and bitter past.

Qu Liuqiao is only twenty-four years old, which should not be the second possibility, so her personal ability must be quite outstanding, and she can even compare with herself when she was in the police academy.

Tang Tian thought like this, he didn't feel embarrassed, he was a very rational person, and he clearly knew how good he was back then.

"Let's go eat first, Team Xiang will come with you, everyone else has already gone back. Qu Liuwan took the walkie-talkie and spoke, then turned around and handed Tang Tian a sweet smile.

"Miss Qu, no, Xiaoqu...... Comrade, did we know each other before?" Tang Tian finally asked this question.

Qu Liu's weak eyes showed a hint of disappointment, and he lowered his head to prevent Tang Tian from seeing his eyes: "I probably don't know it." ”

"Probably?" Tang Tian was puzzled by this answer.

"I know you, five years ago when I was in the police academy, I just entered the school, and I participated in your award ceremony, at that time I was sitting in the crowd like a little radish head, you shouldn't be able to see me, just ......" Qu Liuqiao did not continue.

Tang Tian had not graduated from the police academy that year, and he had a personal third-class merit, and he was regarded as a legend back then, but not long after that, his girlfriend had an accident, and his life trajectory also changed.

Qu Liuqiao seemed to know Tang Tian very well, and after mentioning this topic, he began to be silent, and until he stopped, the two of them didn't say a word.

The old fox Xiang Yu's car was following behind them, Tang Tian kept an eye on the behind, and sure enough, he saw that the old fox in the black SUV behind him was staring at his car with interest.

When Xiang Yu noticed that Tang Tian was also observing him, he put away the expression on his face, but it was too late.

Xiang Yu's expression at that time, the only adjective Tang Tian could find was 'obscene', as if an expectant voyeur was peeking at something with great interest.

'The old fox knows that Quliu knows me. Tang Tian told himself so, is there a game he hasn't seen through yet?

In normal times, Tang Tian would definitely try his best to find out what kind of medicine was sold in the old fox gourd. But now, the Huayuan community, where the crime occurred, is on the side, which has attracted most of his attention.

"Let's eat something first. The old fox beckoned Tang Tian and Qu Liuqiao to sit down at the table outside a small shop, "In my experience, people who can do this kind of case are very particular about rituals, since it is twelve o'clock every day, then no matter how difficult it is, he will definitely not be earlier than this time, now that it is just dark, we still have a lot of time." ”

Tang Tian was deeply convinced of the judgment made by the old fox: "It's just that now the female landlady must also know about the 19th floor of the building with her jumping off the building last month, how much does she know, will there be panic? If these variables are calculated, the time when the murderer committed the crime may also change." And ......"

Tang Tian paused: "The victim of this case has called the police, and the two of us ......" He pointed to himself, and then to the old fox Xiang Yu, "You don't have the right to participate in the case, right?"

To be precise, this matter should be handled by the local police station, even if there was a murder case due to a similar incident not long ago, the matter must be taken over by the criminal police team.

The responsibility of the Special Incident Investigation Bureau is to deal with outstanding cases that cannot be handled by normal criminal investigation methods, as well as cases that have to be closed early due to some major reasons.

Five years ago, Tang Tian's incident at the police academy belonged to the latter, and the incident happened at the police academy, and the students of the police academy did not mention it.

What's more, no matter who looks at the case back then, there was no suspicion, and the deceased committed suicide and jumped off the building. The doubts in everyone's hearts are just because 'I think that it is impossible for that female student who is as good and cheerful as Tang Tian to commit suicide', but no one can prevent the detection of a case because of this psychological feeling, Tang Tian is the only exception.

At present, the Special Investigation Bureau is not qualified to intervene in this matter.

Tang Tian said this to the old fox, if the Special Investigation Bureau did not have the qualifications to handle the case, he might as well come out and do it alone.

"Don't worry, isn't this a small song here? You'll just follow her later. Xiang Yu said meaningfully.

Qu Liu's weak face flushed: "Team Xiang, what are you talking about, with your experience and qualifications, if you want to go to the scene to investigate, even if our director is here, this is a strong support, I just follow the chores." ”

"Ouch. Xiang Yu stared at the weak meandering stream in shock as if he had discovered a new continent, "Is this still the weak meandering stream I saw a few days ago?" Okay, okay, let's not talk about it, this matter is settled." After eating, we went to the informant's house and focused on checking the window. ”

After five years, re-examining the old case is tantamount to letting Tang Tian experience the pain of the year again, and he has been trying to restrain himself.

It's too similar, everything is too similar, he has to go to every scene to check, he didn't move a bite of the dishes called by the old fox, Qu Liuqiao also said that he was not too hungry, the old fox stared at a few dishes alone, and finally had no choice but to pack it, nagging in his mouth that Jia Zuozhen was cheap, and took Tang Tian straight to the scene.

This time, the informant lives on the seventeenth floor, which is a new type of residential community, with one floor per household and the corresponding floor, and can only be swiped by the person who lives on the corresponding floor to go up, and there is no other way.

There is a staircase next to it, but as long as the elevator is not broken, the door of the staircase is generally locked, and only the security room can get the key.

After Tang Tian observed the surrounding environment, Xiang Yu was already beckoning Tang Tian into the elevator.

"There is surveillance in this elevator, and after the first case, we have checked the monitoring of the elevator, and during that time period, the elevator has been parked on the first floor, and no one is using it. Qu Liu introduced the case to Tang Tian in a weak whisper, and the plainclothes comrade who swiped the card upstairs next to him was stunned.

"Also, after our investigation, the current informant and the victim last month do not know each other, and may have met occasionally in the elevator, but only nodding acquaintances. Qu Liuwan finally said, "We have conducted a comprehensive investigation, and so far the social circle of these two people has not found any intersection, that is, the murderer may have committed the crime randomly." ”

"If it's a random crime, these murder plans are perfectly a bit excessive. This is murder, and the murderer has to torture the souls of the deceased before killing them, and there must be an intersection between the two victims, and somewhere, they have a vendetta against the murderer. Focus on the people who live in the Huayuan community. ”

Tang Tian's tone of voice changed, and he was the same as before.

"Team Xiang, you go to the seventeenth floor first, and I'm going to take a look at the residents on the nineteenth floor. Tang Tian made a temporary decision.

There are still four or five hours left before 12 a.m., and there should be no problems with the informant at the moment.

Qu Liuwan just glanced at the plainclothes comrade, and the comrade immediately spoke: "Mr. Tang, you are the person brought by the Xiang team, if you want to see the scene, you can naturally do it, and I am responsible for accompanying you throughout the process." ”

"Aren't you coming along?"

After Xiang Yu stepped off the elevator on the seventeenth floor, he turned his head to stare at Qu Liuqiao.

Qu Liuwan sighed softly: "No need, as long as he goes to the scene, it is superfluous to follow anyone next to him." ”

"But he's been gone for five years, and I've tested him, and now he's not as sharp about clues as he was five years ago. Xiang Yu said earnestly, "But even if he doesn't meet the requirements, everything is worth it." ”

Qu Liuwan rolled his eyes at Xiang Yu: "I bet it won't be long before you'll be ashamed of what you just said." ”

"Hahaha, that's the best, if my shame can be exchanged for a good player, I'm more than happy. Xiang Yu didn't care at all about Qu Liu's weak words.

On the contrary, Qu Liu's expression was gloomy after hearing this: "If it weren't for the fact that only you could save him, I wouldn't have let you find him." In that little house of yours, the tablets are running out, right?"

At the same time, Tang Tian arrived on the nineteenth floor, and when he came out of the elevator, Tang Tian felt a yin wind hitting him.

The windows in this corridor have not been closed, even if it is already above the ash layer, after all, it has been more than ten days since the incident, and there is already a thin layer of dust in the corridor.

"Using conventional psychological analysis, after committing a crime, the murderer often finds an opportunity to come to the scene to see. But this time the murderer of the case is very thoughtful, he is a ghost, every step of the crime, is planned to be flawless, a perfect criminal, there is no need to return to the scene, he has this confidence. Tang Tian's fingers were stained with a little ash in the corridor, and he looked back at the slightly embarrassed plainclothes.

"Well, the door is over there, I'll open it for you. In order to alleviate the embarrassment, plainclothes hurriedly walked forward, "Mr. Tang, you are not really here to hunt ghosts, have you? I have always been involved in this case, if there is a second person here besides the victim, it must be a ghost." ”

"The murderer who can't be caught is the ghost, for example, ......" Tang Tian stared at the top of the plainclothes head, and when the plainclothes turned around, he happened to see Tang Tian's eyes looking at the top of his head ethereally, and his face turned white with fright!

He kept his head twisting and turning around like this, and he didn't dare to move for a while, and beads of sweat rolled down his cheeks: "Tang ...... Mr. Tang, what do you see? What is there in my head...... Stuff?"

"Hmm. Tang Tian's gaze slowly moved down, meeting the eyes of the plainclothes, "There is indeed something strange here, that thing is above your head." ”
