The problem of smoking should be considered a personal problem, but Song Tao still explained, "I, I probably learned to smoke after becoming a police officer." ”

Then things are much more interesting, Liu Yan thought about it a little, "Then, you haven't been a policeman for a long time, right;

Song Tao nodded, "Sort of, I've done a lot of training before." ”

"So, in other words, you didn't smoke when you were a teenager, but why did you suddenly learn to smoke after becoming a police officer?"

Song Tao glanced up at Liu Yan, "What's the matter, you want to say, it's not good to smoke?"

Liu Yan scratched her head in embarrassment, "It seems to be a little interesting." ”

But at this time, it was really strange and ambiguous to suddenly take care of other people's private affairs, Liu Yan changed her words and said, "Actually, it's nothing, I just think that you don't have to smoke at all." ”

When Liu Yan said this, she began to regret it, what is this called, why is it more and more wrong, it seems that she is a little too wide, a feeling of inexplicable taking care of her boyfriend?

Before Song Tao could speak, Liu Yan began to defend again, "Actually, I just think that you are a little bad for smoking;

Song Tao looked at Liu Yan strangely, and said lightly, "What's the matter, just say whatever you want, there's nothing to be embarrassed about." ”

The more she talked about this matter, the more chaotic it became, Liu Yan waved her hand and said impatiently, "Forget it, it's nothing important, let's discuss the right thing." ”

Just as the two wanted to discuss the matter seriously, the door of the laboratory suddenly opened, and Song Tao hurriedly stood up and said to the white-clothed policeman, "How is it, how is it, have you found any important clues?" Song Tao's words were full of anxiety and urgency.

The white-clothed police officer hesitated slightly, but quickly said, "There are a lot of fingerprints on it, and there are also mixed ones." ”

Hearing this, Song Tao became nervous, "Then what? Can you still investigate the clues?"

But Liu Yan's side felt that something was not right, so much black tape, in terms of area alone, there were not fingerprints everywhere, right?

Liu Yan said, "That, is it all like this?"

The white-clad officer nodded, "Well, it's really like this." ”

"So, there's not a single hole or anything like that?"

"This one doesn't, and the fingerprints on it are a bit repetitive, so it's not easy to extract fingerprints, but now we're still trying. ”

What the hell is going on? The fingerprints in the simple black tape have reached the situation of repeated superposition, which is really incomprehensible, Liu Yan held her chin and said lightly, "So, is there anything else?"

The white-clothed police officer answered for Liu Yan again, "Well, in addition to fingerprints, there is also sweat and the like, so it is even more difficult to conduct laboratory investigations." ”

Liu Yan nodded, it seems that it is really a bit messy, as for the sweat just mentioned, maybe it is because of the summer, and she sweats from time to time.

But Liu Yan suddenly grasped the point, "That, Mr. Policeman, then, can you investigate the fingerprints of one of them? ”

This is really the level of the test, and the white-clothed police officer nodded, "Well, we will also go to the test in this direction." ”

It seemed that there was still a slight difference, and Song Tao said, "So, when will you be able to test it?"

"It's hard to say, but it shouldn't be too late. ”

Song Tao glanced at Liu Yan and said to the white-clothed policeman, "Then let's do it, I'll go back to the office, if there is a situation, then please tell me as soon as possible." ”

"Well, that's fine. ”

"Well, I'm sorry for you. After speaking, Song Tao walked over and patted Liu Yan on the shoulder, "Why are you stunned, go back." ”

In fact, the reason why Song Tao wanted to go back to the office was mainly because he didn't want Liu Yan to work too hard, after all, people came to help, and they couldn't make the family too tired, right?

When Liu Yan wanted to ask something more, she was dragged away by Song Tao's hand, and Liu Yan, who was dragged away, suddenly said, "Song Tao, what are you doing?"

Somehow, Song Tao suddenly felt a little shy and lowered his head, "It's nothing, I just want you to rest and rest, and when the test results come out, I will naturally tell you." ”

In this way, it is okay, but Liu Yan wondered, hasn't Song Tao been very nervous about these cases, why did he suddenly relax?

With this question, Liu Yan said, "I said Song Tao, what's going on with you today? ”

Song Tao was stunned, and did not recall the changes in his emotions since today, from nervousness to now taking the initiative to rest, all this Song Tao is still a little vague, it may be because of Liu Yan, so Song Tao doesn't want Liu Yan to be too tired.

Song Tao said, "Hey, what's wrong?"

Forget it, it's better not to ask about those things, Liu Yan retracted her hand with her strength, "Actually, it's nothing." ”

Although the two did not hold hands, Liu Yan still followed behind Song Tao, and Song Tao said leisurely, "Oh~, it's okay." ”

After the two entered the office, Song Tao asked Liu Yan to find a place to sit by herself; in fact, there was no need to say these words, Liu Yan had long been used to being here, and naturally it was not as strange as at the beginning.

As soon as she sat down, Liu Yan said, "By the way, Song Tao, have Zhou Wen's cases been handled?"

These things had already been dealt with while Liu Yan was lazy to sleep, but Liu Yan didn't know it at the time, Song Tao said, "Well, it's been handled, and it's been brought to justice, there's no problem." ”

Liu Yan nodded, relieved a lot, "That's good, that's good." ”

But there is another big problem in front of him, Song Tao asked, "By the way, Liu Yan, what do you think of the things in the elevator?"

Liu Yan scratched her head, "It's impossible to commit suicide, perhaps, it should be him who kills." ”

Song Tao can't be sure of this, maybe it can really be regarded as his killing, but the old man in the elevator died like this, it's a little too exaggerated, right? Song Tao asked, "Liu Yan, what do you think of that old man?"

Why did this sound weird, Liu Yan blinked, "You want to ask, does the old man have a heart attack?"

"Yes, yes, that's what I want to ask. ”

At this time, Song Tao and Liu Yan remembered, at that time, the two of them did not ask this point clearly, it seems that they need to call to ask; Liu Yan was depressed for a while, she seemed to have thought of this question at that time, but in the end she inexplicably ignored it, and now, she can only recontact the family of the deceased.

Liu Yan was a little embarrassed, and said weakly, "That Song Tao, why don't you contact the deceased's family Wu Dong again?"

That's all there is to it, Song Tao nodded, "Okay, I'll investigate this matter later, but it's not that there are no fingerprints on the black tape, but a lot of fingerprints, what do you think?"

Liu Yan was silent for a moment, and then said, "Actually, I think this is very strange, generally speaking, fingerprints should not be left, even if fingerprints are left, they should not be so many." ”

Suddenly, Liu Yan realized a problem, these black tapes should be rolled up in the same shape, but it is impossible to stick fingerprints on the rolled part of this shape of film, unless someone touches the surface again when using it.

But the question arises again, where will there be a murderer, who will be stupid enough to leave his fingerprints?

However, Liu Yan still caught a clue, that is, to find out the fingerprints of one of them, first find out the origin of the black tape, and some subtle clues.

Liu Yan said, "By the way, Song Tao, don't you think it's a little strange! It's that fingerprint, I heard that there are too many fingerprints, it's hard to identify, what do you think of this?"

Song Tao was silent for a moment, scratching his head, and then came to his senses, "Oh, you mean, there's something particularly strange about this." ”

"Perhaps, but there is another point, and that is that it is impossible to have fingerprints on unopened rolls of tape. ”

Hearing this, Song Tao was stunned, and he couldn't figure it out, and after a while, Liu Yan helped answer, "Actually, I think that the person who may commit the crime does not refer to one. ”

"Not just one?" This statement was so strange that it was really unexpected by everyone, so Song Tao deliberately asked this question, hoping to ask it clearly.

Liu Yan immediately explained, "Actually, what I said is not reliable, I have to see if the fingerprints on the tape are from multiple people, if it is really different fingerprints of many people, then my guess is right." ”

Many people committed crimes, which was difficult for Song Tao to accept, after all, the area he managed was relatively calm before, so he didn't want to believe it.

There is another point that Song Tao doesn't want to believe, that is, the method of this case is still relatively simple, and there is no need for many people to act; Song Tao suddenly said, "That Liu Yan, are you thinking too much? I think it may just be a coincidence." ”

Coincidence I'm afraid this is not very appropriate, right? But then again, the two are just hypothetical, and the final results of the black tape test have not yet come out, and if they do, then it will be much easier to explain.

At this time, Liu Yan blinked, her words were indeed not comprehensive enough, and said weakly, "Or, let's wait for the test results to come out and take a look?"

The matter should have been handled in this way, but no matter how much it is discussed now, it is just a theory and does not have much effect; Song Tao said, "Okay, let's wait." ”

Liu Yan got up from her seat, poured herself a glass of water, and also poured a glass of water for Song Tao.
