was asked by Wang Jianfei, Qiu Shuyu's old face darkened, and he said: "Comrade police, I have round-trip tickets for business trips, and I am sure that I have slept all day after I came back and never went out at all, but you have to ask me to find someone to prove it, I really can't prove it, my hometown is out of town, I work hard in Dongyang alone, and now I am still a single dog, I don't have a girlfriend, who can I find to prove it to me, I ......"

Wang Jianfei is not a fool either.

Although his work focused on arrest rather than torture.

But with more and more cases, some psychological micro-expressions and so on have also become familiar with a lot, not to mention that Wang Jianfei's learning ability is very strong.

Judging from Qiu Shuyu's performance, he is not lying.

Moreover, we all know that the man in black behind this is not so mentally retarded, of course, we are not insulting Qiu Shuyu's IQ, at least, in the process of playing games with us again and again, the performance and means of the man in black are much more powerful than this Qiu Shuyu.

Subsequently, I took Xia Xixi and closely went to retrieve the monitoring of the elevator in the Mingshu apartment in the last two days, checked Qiu Shuyu's round-trip ticket for a business trip, and Qiu Shuyu's takeaway order for a meal a day after sleeping at home, it can basically be determined that Qiu Shuyu's car was driven by someone else!

Wang Jianfei scolded: "This guy! It's just cunning!! ”

Xia Xixi said: "According to the procedure, we are going to bring Qiu Shuyu back...... Temporarily detained. ”

I shook my head: "Don't." ”

"Since he's not a murderer, why bother."

Wang Jianfei agreed with my statement, took a puff of cigarette and said: "We are the Red S group, we can't do the bastard thing of arresting people casually for the sake of inviting merit, but the car still has to be impounded, let Xiao Wang drive the car back for a while, and go for a trace examination." ”

"Okay."

Subsequently, we kept an eye on Qiu Shuyu in the recent period, and if there was any situation, we must call the police as soon as possible, and if we have any other discoveries, we will come to him again to seek cooperation.

Finally, Wang Jianfei apologized for breaking through the door and rushing in to subdue him at the beginning.

Qiu Shuyu didn't care about complaining about anything, and nodded vigorously: "Comrade police, I am really grateful for your arrest of me in a daze, you can rest assured, if there is anything that needs my cooperation in the future, I promise to spare no effort to cooperate with you!" ”

"Okay, I'm really sorry, I'm leaving, but your car may not be able to drive in the next few days, and we still have to do a trace inspection."

"Hey, no problem, no problem, I'll send you ......"

"Let's stay......"

On the way back, I probably asked Wang Jianfei and Xiao Zhang about the specific situation when they went to the other two cars to check.

Wang Jianfei said: "The Geely car, is an employee of a sofa furniture factory, in recent days has been working overtime all night to catch up with orders, never went out at all, the car passed by the section of the bar, is to take the boss to talk about business, the people in the factory can prove, monitoring can also prove, excluding suspicion." ”

"Where's the other Cadillac?"

"That XT5 was the car of a middle school principal, and he went to the bar the night before, but after comprehensive clues, there is no suspicion."

"I'll ......"

Xia Xixi shook his cuffs: "A middle school principal has opened a Cadillac XT5?" How much does this car cost? ”

"The top version has about 500,000." I say.

"It's really rich." Xia Xixi's eyes were red and said: "I didn't expect to be a principal and make a fortune, but it's a pity, I'm afraid I won't have the opportunity to drive a 500,000 car in my life, what a tragedy in my life......"

"Come on, you." Wang Jianfei said: "My uncle who is in charge of water conservancy also drives the president of Maserati, what is the result?" It's been in for a year and a half and hasn't come out, it shouldn't be your own, you have to pay the price if you enjoy it, as the so-called, unrighteous and rich, to me like a floating cloud, hehe, this year, it's better to make some clean money down-to-earth. ”

I nodded, sat in the back of the car and smoked a cigarette, thinking about the case.

After returning to the city office, we went straight to the trace inspection team, and the Cadillac had already begun to enter the trace inspection stage.

The results came back two hours later.

But it's a pity.

No fingerprints were extracted from the steering wheel except for the owner Qiu Shuyu himself.

In the crevices of the seats, on the footrests, there is no residue of hair and skin keratin.

It can be said that the man in black behind it did borrow this car, but it was premeditated, and he made all the preparations.

And the trace inspection work is not without results.

After the technical department's full investigation, combined with the engine start serial code provided by the manufacturer, we determined that the car had been forcibly started.

This further proves that Qiu Shuyu's car was not driven by himself that night.

There is a catch.

But it is equivalent to the clue is broken.

In the office, Wang Jianfei and I were smoking, and Xia Xixi was playing with coffee cups and spoons, frowning and thinking.

This feeling is really unpleasant and depressing, as if there is a person behind the back who has a knife on his head, but there is nothing we can do, and the feeling of paleness and weakness makes people almost crazy!

Professor Wu was silent, and it took a long time before he spoke: "Now that car manufacturers have closely integrated the engine serial code with keyless start, it stands to reason that the safety factor is already very high, and this person can still hack into the code to start the engine...... What kind of talent is this......

Wang Jianfei said: "Bao Buqi is still a cutting-edge scientific and technological talent!" ”

"Well, cutting-edge technology talents come to fight against the police, this plot is really nice!" Xia Xixi knocked on the table: "This is simply a typical antisocial personality!" Psychological pathology! Sick! ”

This explanation is quite reasonable.

However, I always feel that it is not particularly reasonable.

At least, he doesn't seem to be targeting the entire Crime Squad or the Red S in a broad sense, because he hasn't been in the sight of others, but he has only appeared in front of me.

I said, "It doesn't have to be an antisocial personality, maybe it's a grudge against one of us." ”

"Then it can only be a grudge against you." Xia Xixi spread his hands harmlessly and said: "After all, it's only you, I've seen him many times!" ”

"Hmm." I nodded in acknowledgement.

Wang Jianfei said: "Otherwise, you will live in the city bureau during this time, it is not safe for you to go home, and now we are equivalent to being in the Ming ...... Besides, the bombings have happened, this kid really dares to do it...... This bombing is not that serious, but what if there is a next time? ”

"That's right!" Xia Xixi also highly agreed with Wang Jianfei's opinion, and reminded: "I went to the laboratory to see it, and the fried pellet is a homemade thing made of ammonium nitrate and glycerin, and the murderer is not only a high-tech talent, but also a chemical talent!" ”

Professor Wu said: "Homemade bombs are not high-tech talents, theoretically anyone who studies chemistry in college can make this kind of thing, but these materials are restricted from being purchased!" ”

"I think our next step is to check the places where you can buy ammonium nitrate in the city, and then investigate the buyers one by one!!" Wang Jianfei suddenly opened his brain, patted his head, and said!

"It's a detection direction, but it's too difficult...... Professor Wu shook his head and said: "There are many chemical raw material factories in the city, and there is also a fertilizer factory in the suburbs, although ammonium nitrate is restricted from purchasing, but the amount is very large, and it is impossible to achieve the ideal comprehensive control, the other party is such a smart person, if he wants to buy ammonium nitrate, he has countless ways to choose, we aimlessly investigate, it is a waste of police force, which is equivalent to falling into a trap, but there is a little doubt......

I looked at Professor Wu and asked, "Is it a dash cam?" ”

"That's right!"

Professor Wu looked at me approvingly.

I've really been thinking about dashcams for a long time.

The murderer, such a smart and cautious person, drove Qiu Shuyu's car to mislead us, be alone, and teach us a lesson, but why not delete the dash cam? He can be careful enough to drive five kilometers without leaving any traces, so it is not difficult for him to completely remove a driving record video.

He couldn't be incapable, and he couldn't have forgotten.

That's either on purpose! He's deliberately leaving us some clues.

Therefore, checking the dash cam is still a top priority!

"Yes!"

My eyes suddenly lit up: "The murderer is very likely to have done it on purpose!" ”

Professor Wu said: "This is exactly what I have been thinking about, the murderer's homemade fried balls injured us, and the number is not large, I wonder if he is giving you a warning or what we often say, give us some color to see......

"Through past cases, we can also find that this man in black is almost everywhere, and he always has to intervene in every mega murder case......"

"But we don't have the ability, and we don't pay special attention to arrest him, so the murderer has always been unrequited, and he can't be anxious, he is eager to be valued by the serious crime team, arrested, and arrested, and he is eager to see the police being dizzy by him, so that he can have pleasure and be satisfied, but unfortunately in the previous case, we ignored him by mistake, and it is precisely because of this that he can't wait, this time, he chose to take action himself...... Blow us up! ”

"Yes!"

I nodded: "This is a typical perverted criminal mind!" ”

"Hmm...... So, can we understand that he deliberately put the dash cam and did not delete it, leaving us a clue? ”

"Can we also understand that we don't need to deliberately look for clues to wind up ourselves, but just wait and see......

The killer is already mad now, or we can wait and see what happens and wait for him to reappear, and his next appearance may not be too long at all......"

"This feeling is good!" Wang Jianfei snapped his fingers: "Turn the disadvantage into an advantage, lay a net and wait for him to send it to the door, this is much more comfortable than us spinning around like headless flies!" ”

"Yes." Professor Wu said: "In fact, the murderer likes to see us wander around after being misled, as long as we can stabilize and not let him be satisfied, he will definitely show up!" ”

A problem that was originally unsolvable seemed to suddenly have a bright direction, and everyone felt a little better.

But at this time, Xia Xixi looked worried and said in horror......
