The room has been inspected several times, and almost all the suspicious items have been collected, and there is hardly a single item that can make Wu Fan practice. ￠￡

Holding tweezers and a plastic bag, Wu Fan pretended to walk around, his eyes were suddenly fixed on the wind chimes hanging in the window alcove, and he said, "Brother Qiao, can I accept that wind chime?"

Qiao Xiangyang glanced at the wind chimes in the window alcove, he knew that the wind chimes had been seen by everyone from the first survey of the scene, but everyone felt that there was no possibility of becoming evidence, and it was impossible for the murderer to climb in from such a dense window bar, so he didn't take it seriously.

Without any hesitation, Qiao Xiangyang nodded.

Wu Fan glanced at the ground, walked around the place and obstacles in the circle to the table in front of the windowsill, and then stepped on the table.

With the naked eye, the wind chimes in the wind were swinging, and the strong light outside enveloped the wind chimes, and if it weren't for his eyesight and eyeball coat and ordinary people, he wouldn't have been able to see the clear outline of the wind chimes clearly, let alone the hair hidden in the tube.

And standing at such a close distance, Wu Fan suddenly found that the steel bars of the metal window rails hanging the wind chimes were mottled with light and shadow, and there were several places where there were slight differences with the steel bars in the gaps next to them.

Wu Fanyun gathered true qi, Wu Fan's eyes had an extra light-colored spot, this spot was a rotating nest, like a floating pupil, in this pupil, Wu Fan could clearly see the slightest difference on the steel bar in front of him, especially he could see that the two steel bars under the wind chime were more than 20 centimeters different from other places, and the paint on it had some traces of slight friction, which was very subtle. There is no difference with the naked eye, but there are very fine filaments in those subtle places.

"What are you looking at, why are you stunned?" At this time, Qiao Xiangyang waited for a while. urged.

"Brother Qiao, do you think the murderer will come in through the window?" Wu Fan asked inquisitively.

"How is that possible? such a small gap. And this is still the fifth floor, and there is no place to climb outside, how can anyone climb up and get in through such a small gap, and kill people so neatly......"

"Bone shrinking and gecko skills, have you heard of them?"

Wu Fan has seen the gecko spring, and knows that the gecko can climb on the ceiling of the roof, this kind of wall is not difficult for people like her at all. But he believed there was. Nangong Sword can turn qi into a sword, a miracle at that time. Not to mention that the mysterious gray substance in his body is almost omnipotent, which is already beyond human cognition, so he believes in the existence of bone shrinking gong even more.

"Boy, you've read too many martial arts novels, aren't you? Bone Shrinking Skills, Gecko Skills? What are you kidding, those are all out of science. I warn you that in handling cases, we criminal police should stress facts and seek evidence, be down-to-earth, and base everything on science. Don't think about it every day......"

Qiao Xiangyang is Chinese New Year's Eve two years old today. It's been ten years since I joined the criminal police team, although I don't say that I have repeatedly solved strange cases, I am also a veteran in solving cases, and my experience is not worse than others.

"Brother Qiao. I think there is something wrong with this wind chime, as well as these two steel rods, which have traces of friction. At a certain angle of the sunlight, faint fibers can be seen...... Hey. How can there be a hair in the aluminum tube of this wind chime?"

"What fiber...... What's the head...... Be careful, don't move!" Qiao Xiangyang glanced at him. Seeing Wu Fan's hand holding up the aluminum tube of the wind chime, he rushed over. At the same time, he took out his mobile phone and dialed the European side.

These surveys have not found foreign bodies, and if hair and fibers are found, although they have not yet been confirmed to be evidence and clues, this is also a new discovery. If......

"Report to the captain, we found a foreign object in the room where the crime occurred, a hair and fibers on the window guardrail. Please have someone from the technical section come back as soon as possible. Qiao Xiangyang said anxiously to Ou Fang on the phone.

Ou Fang had already reached the first floor at this time, and when he heard Qiao Xiangyang's words, he was immediately shocked, and without saying a word, he waved his hand and said: "The people from the technical department returned to the scene with me, and there are new discoveries!"

The wind chimes were carefully removed, and the two rebar rods were scanned by the spectrograph. Then the two steel bars were cut off and brought back to the criminal police team for further analysis.

The hair had to be taken back for identification to determine whether it was left by the victim, and the images taken showed that there were indeed fibrous foreign bodies on it, and the composition and origin of those fibers had to be taken back and analyzed by computer before they could be known.

When the technicians were working, Qiao Xiangyang reported the discovery process and Wu Fan's suspicions to Ou Fang and Sun Weiguo.

"Good, it's a bold association. I haven't seen the bone shrinking skill, but the sea of people is vast, and there are countless strange people, I saw a similar introduction on TV a few days ago, saying that there is a person in Yanjing City who can shrink the bones, so Wu Fan's assumption is not unreasonable. Also, the five-story building is indeed very high, the walls are smooth enough, there is no place to climb, I haven't heard of gecko skills, so how did he come up?"

The European side's insight is indeed beyond ordinary people, so that several criminal police officers who are watching seem to see hope.

"Why do you have to come up from below? Can't you hang down from above?" Wu Fan interjected in surprise at this time.

"Yes, if you can't come up, you can tie a rope and come down from the roof!" Sun Guosheng was the first to react to Wu Fan's question, "Let's go to the top of the building, if we can find clues in the corresponding position above this window, it means that Wu Fan's assumption is correct." ”

Just do it, except for Ou Fang who stayed, everyone else left the room and ran towards the fire staircase.

The roof is huge, and vegetables are grown on it. As soon as it rained, the muddy water in the vegetable garden flowed everywhere.

Seven or eight people quickly found some disordered remnants in the corresponding location of dormitory 515 on the rooftop: a cigarette butt that had been washed away by the rain, hemp fibers hanging from the exhaust chimney body, and two lines of incomplete, solidified footprints.

The footprints were only in some places, on the concrete floor at the edge of the canopy, and they were blurred by the rain, and the soles of the shoes could not be seen. Only the shape of the dry mud could make out that it was a footprint. When I entered the canopy, the footprints were gone. But it is conceivable that this person changed his shoes or put a clean plastic bag on his shoes. Let the footprints disappear.

This is a very significant discovery.

As soon as the European side got the report, he immediately called the administrator of the dormitory and began to inquire.

"The roof is locked, how can anyone grow vegetables on it?" Sun Guowei asked the dormitory administrator.

It was Lao Cai of the property, he said that it was empty and empty, so it was better to plant some food, which would save money and eat safe food. Everyone knows about this because it doesn't affect other people's lives. I just turned a blind eye. ”

"Who is Lao Cai? Who else has the key to it besides Lao Cai?"

"The keys to the rooftop doors of these buildings are hung in the property office, and whoever uses them and who takes them has never been careful. ”

"And on the night of July 18th, who used the key there?"

"I don't know, I'm just the administrator of this building, and I don't know about the property office. ”

“......”

When interrogating people, Wu Fan was also present. But he can only be used as a recorder, and he can record every question and answer in detail and word for word in the notebook.

No one expected that more than a dozen veteran criminal policemen did not find clues. But it was discovered by a newcomer who had just been on work for less than four hours, and if the test results on the technical side came out, whether the fibers and hair on the steel bars belonged to the victim, there would be a new breakthrough in the case. Wu Fan is the first achievement.

The Interpol team is a united organization, all the police officers are racking their brains to solve the case, and no one will be jealous of who found the clues. Whoever has made a meritorious service, as long as he can solve the case. In addition to looking up at him, everyone is trying their best to complete the unfinished business.

Soon. The progress of the technical section is going very well and the results of the inspection are out.

The hair was not the victim's, it belonged to a man. The capillary fiber on the steel bar is a new type of carbon acetate fiber, which is often used in the production of sports tights or fitness clothing. It is because of extrusion and friction that it is rubbed off by the burrs on the surface of the steel bar, because the action of rainwater solidification is left on the steel bar; the hemp fiber chips on the roof are a kind of remnants on the hemp rope used for engineering, according to the traces, it can be judged that this kind of rope has a thumb thick, can withstand the inertial impulse of thousands of catties.

However, knowing this is only to find out the process of the perpetrator, who is he, why did he kill these two people...... and so on are all big question marks that need to be answered through complicated investigations.

The eight people in the five groups were all separated at this time, after interrogating the administrators of the building, Wu Fan and Qiao Xiangyang were arranged to go to the property to find clues to the roof key, and some others went to find clues about carbonate fiber, some went to check the clues of hemp rope, and some went to the electronics factory to inquire about the work of the two victims, and some people asked Donghai if there were any people who could shrink bones.

Because the people who were close to the victim and those who had opinions about them had been checked three days ago, the focus was on the work at hand.

These things can not be figured out in a while, and in the afternoon, suddenly people from the electronics factory came to the criminal police team and said that Fan Zhongheng (the senior engineer who was killed) had a new process and new process file in his computer, and this technology is the most advanced of its kind today, in addition to saving a lot of costs, it can also improve the quality of the ultra-micro processor product by two percent. Because of the needs of production, the factory representative needs to take it out of the criminal police team, or make a copy.

This was a reasonable request, and the Interpol team naturally agreed to copy the documents. However, in the evidence room, the criminal police handling the case did not find the evidence of the laptop at all. On the list of exhibits, the laptop was also not found.

As a result, the 718 case has made qualitative progress, and the motive for the crime has become clear all of a sudden.

Buying murder and stealing technology has suddenly become the most important killing factor.

However, Wu Fan was a little strange and did not dare to agree with this judgment.

In modern society, the development of technology is increasingly dominating the development of the economy. As big as a country, as small as a business. For enterprises, commercial espionage is not uncommon, but they are all seeking money, and they will never kill people for stealing technology unless they have to. The suspect in the case can quietly enter the dormitory of the deceased, and his kung fu is much higher than that of ordinary people, and even if he does not kill people, he can steal the computer, so why kill people? Isn't this provoking fire? If he hires a murderer to intercept goods, it must be a professional killer or a professional person, and such a person will never do a thankless task, that is, they will never kill people easily.

If that's not the reason, what is it?(To be continued, please search, the novel is better and faster!)
