Everyone just saw the plastic bottles, no, it should be said that the plastic bottles of mineral water were mutilated, and as for the clues, I'm sorry, no one saw the slightest.

"The devil is in the details."

Jiang Hao directly spit out a hint that he thought his artistic conception was very far-reaching, if it wasn't for the explanation of the tracing technique, even if he found the entire plastic bottle, I am afraid he would not have thought of this backward method of solving the case.

"What are the details?"

Feng Chaoyang's eyes widened, and the keen and stern skills he had cultivated over the years in solving cases made him the first to discover a broken detail of the plastic bottle.

This detail is the barcode left on the edge of the plastic bottle, it seems that in addition to this detail, there is nothing to be ignored and forgotten, he asked tentatively: "Is it the barcode left on the bottle?" ”

"Barcode?"

The people in the Criminal Investigation Department immediately suddenly looked at the barcode that had been ignored, and patronized the bare bottle, and even ignored the barcode left on it!

"Professor Feng's observation is indeed nuanced, and the overlooked clues I am talking about are indeed referring to magic barcodes, because this is too needed."

Jiang Hao carefully showed a circle of broken barcodes, explaining: "Barcodes people will often come into contact with in their lives, it can be said that as long as they shop, they will encounter the problem of barcodes, there is a humorous person, the barcode is compared to the ID card of the item, a barcode has never belonged to only one kind of item, this is an indisputable fact."

As long as we have the barcode of the item, by investigating the source of the barcode, we can find out who bought the item from where and swiped the barcode.

If the store where the purchaser is purchased is equipped with a camera, it must have recorded all the characteristics of the person who purchased the item and the address of the purchaser.

As long as you can get the video, you can easily know the appearance of everyone in Li Mazi's group, and as long as they are still in Zhongzhou City, you can easily arrest them. ”

Jiang Hao talked eloquently, but every word he said was the information fed back from the refining and tracing technique, and it was narrated after organizing the language, which could be said to be irrefutable by anyone.

"But the barcode seems to be very incomplete, and the incomplete barcode can't be checked at all, which is really tricky."

Everyone looked at the barcode on the plastic bottle, the barcode after the baptism of fire, there were only two-thirds left, and the remaining one-third could not find any hope at all, the people in the Criminal Investigation Department secretly felt a pity, if they had searched for this barcode that was crucial to solving the case earlier, maybe there would have been clues a long time ago, but now everything has become ethereal and illusory.

"It's true that it can't be used as a clue to solve the case."

Feng Chaoyang knows a little about barcode crime, once they found a barcode, but they ran through a lot of product outlets before they found a little clue.

It is difficult to find the origin of the complete barcode, let alone the incomplete barcode, and it is simply difficult to solve the case.

"I didn't say that the barcode was mutilated, the mutilated part was just left in the burning material, and there was no data on it."

Jiang Hao directly held up the barcode he found and handed it to everyone to check, the barcode number left on the coke was forged by him using manipulation, and no one found it anyway, he said that it was left behind, it was left behind!

"Hurry up and notify someone to record the barcode data and make every effort to investigate."

The people of the Criminal Investigation Division realized the seriousness of the problem, and the looming numbers left on the coke provided a great opportunity for the recovery of the barcode.

"Numbers, why are they left on the coke?"

Feng Chaoyang observed the numbers on the coke and sighed at the miracle of the creator, it seems that God is going to help the police solve the case this time.

"The number of the barcode remains on the coke, which is too normal, the number of the barcode is made of a special material, and when it burns, not only will it not retreat, but the strong chemical reaction will make the number of the barcode react on the coke."

Jiang Hao explained seriously to the puzzled Feng Chaoyang.

"It's amazing."

Feng Chaoyang's eyes flashed with an incredible light, with this barcode clue alone, Jiang Hao far surpassed any kind of evidence obtained by the Criminal Investigation Department at the scene.

Jiang Hao's calmness and composure, broad knowledge, and extensive knowledge made him have a strong interest, and he couldn't wait to forcibly harvest Jiang Hao as an apprentice, but after thinking about it, he still felt that he should take it step by step, and he couldn't eat hot tofu in a hurry!

"Jiang Hao, how do you know that there will be important clues under the Dao?"

The people from the Criminal Investigation Department quickly sorted out the materials and prepared to report the specific process of solving the case this time, but when they filled in the clue discovery column, the name was Jiang Hao, and the specific reason for the discovery, they really didn't know anything about it.

Recalling carefully, Jiang Hao glanced left and right, and then directly pulled the coke and found the plastic bottle, the strange investigation was really incredible.

The people in the Criminal Investigation Department also wanted to know where he had fallen and why Jiang Hao could easily find clues.

"I judged it based on the level of smoke." Jiang Hao naturally didn't mind explaining, anyway, he had already found a reasonable explanation: "The molecular structure of the object material is different, the density is different, the intensity of the reaction when burning is not the same, and the intensity of the disgust color that emerges is also different.

Have you just noticed that the entire burning car, where the plastic water bottles are placed, is emitting thick black smoke, which can only be found when plastic is burned? ”

"Understood."

Everyone nodded suddenly, and carefully recalled that the car was burning just now, but where the plastic bottles were placed, there was really thick black smoke, this is an indisputable fact, Jiang Hao is indeed solving the case according to the abnormal phenomenon.

"That's awesome."

The people of the Criminal Investigation Department looked at Jiang Hao's ability to observe the shortlisted, and cast a look of admiration, the masters of solving cases have seen a lot, and they have seen a lot of famous names, and carefully ranked the masters of solving cases in their memory, Jiang Hao can definitely rank in the top few.

"Any clues?"

The people in the Criminal Investigation Department changed their arrogant posture and looked at Jiang Hao as if they were asking for advice, and solving the case to the point where Jiang Hao did it casually was really not something that ordinary people could easily compare.

"Then I'll point it out unceremoniously."

Jiang Hao didn't seem to be a polite person, and it was not his character to hide the clues to solve the case in his heart, so he decided to continue to expose the clues left by the Criminal Investigation Bureau.

"There really is."

The people from the Criminal Investigation Department glanced at each other, they were all very surprised, the speed of finding clues is also a little faster, Jiang Hao can find a crucial clue in such a short period of time, in a complex environment, which is already commendable, and Jiang Hao is actually able to find clues, which makes people who have been engaged in criminal investigation work for many years feel very uncomfortable.

"What's the clue? Speak up and listen to it. ”

Feng Chaoyang couldn't wait to urge the silent Jiang Hao, who had just been defeated by Jiang Hao's superb footprint discrimination skills, he was full of curiosity about Jiang Hao, just to know Jiang Hao well enough, and then accept his own account in one fell swoop, it must be a very beautiful thing.

"One of the four must have had his clothes torn because he had gone in such a hurry."

Jiang Hao casually pushed open the car door, and in the gap between the car doors, there was a small piece of cloth, because the cloth was caught by the iron door, so it was not burned by the fire, and it was preserved intact.

"Hmm."

The people from the Criminal Investigation Department took the rags handed by Jiang Hao and hurriedly put them in their pockets, the rags must have been left by Li Mazi and his gang, because the cloth mixed in the closed room of the car would automatically fall off, since it could be perfectly clamped, it must be the clothes of one of Li Mazi's gang, which is beyond doubt.

"Pretty."

Feng Chaoyang praised in an admiring tone.

"Come and see this cigarette butt."

The clues in the burning car were pointed out, to be precise, the clues that Jiang Hao could explain were pointed out, and some clues that relied on the breath to judge, even if he said it, he couldn't explain the basis of his judgment, so he simply moved his eyes to the outside of the car.

Jiang Hao squatted on the ground, then picked up a cigarette butt, got up and handed the cigarette butt to the person in the Criminal Investigation Department, and said with a smile: "This is also important evidence." ”

"We've already done the physical evidence filing, so we don't have to collect this cigarette butt at all."

The people of the Criminal Investigation Division immediately made a suggestion, the cigarette butt contained the saliva of the perpetrator, which has always been used as physical evidence, and the people of the Criminal Investigation Division naturally did not ignore its existence.

"Cigarette butts are not only used to extract saliva to verify DNA, but we can also read more unknown clues from cigarette butts.

Cigarette butts are like a stage, and if you perform on the stage, you will not only leave saliva, but you should take a closer look at the special features of cigarette butts. ”

Jiang Hao picked up the cigarette butt and looked at everyone with a smile, he knew that he was doing something that subverted other people's cognition, but who let himself know all kinds of powerful magic skills, wouldn't it be a waste if he didn't need it, and it would be shameful to waste.

"There are tooth marks on the cigarette butt, but what does that mean?"

Upon closer inspection, the people of the Criminal Investigation Division immediately recognized the difference between cigarette butts, but what does this bite on the teeth really mean?

"Biting your teeth and smoking is a rare smoking habit." Jiang Hao explained unhurriedly: "But all those who like this way of smoking, they all have a difference from ordinary people. ”

"What makes it different from ordinary people?"

The people in the Criminal Investigation Department are confused, isn't it just that the smoking habits are different, what else can be different?

"Once the habit of clenching and sucking is formed, there is no doubt that the smoker's teeth will be yellowed by the smoke oil in the long run.

And judging from the degree of bitten by this cigarette butt, it is definitely an old smoker, and his teeth must be particularly yellow, and he must pay attention to the people with yellow teeth, because it is impossible to tell which one is the murderer of the robbery. ”

Jiang Hao said slowly.

"Hurry up and report this information."

The people in the Criminal Investigation Department have already been convinced by Jiang Hao, and there is no longer the slightest doubt about Jiang Hao's explanation, all that needs to be done is to copy it, that's all.
