"Lao Zhang, what new discoveries have you made?" This is the first sentence Yang Zi said when he came in, he had already seen what Lao Zhang was fiddling with, and he also recognized that it was a quick gel filling mold, he knew that Lao Zhang must have his purpose in doing this, so he directly asked him if he had any new discoveries.

Lao Zhang's guess just now has been confirmed by the model in his hand, this murder weapon is homemade, he turned his head to look at Yang Zi, "hehe" smirked twice, since he promised to come back to help, working with Yang Zi, he actually made this old pedant who had passed the age of the sixtieth century become an old naughty boy, and from time to time he would have to test Yang Zi, otherwise he would tease Yang Zi.

Yang Zi saw Lao Zhang's eyes with a malicious smile, and knew that he was going to make things difficult for himself again, but at this time, he was not as good as he was at the beginning, on the one hand, he had been carrying out this work for a long time, and on the other hand, because under Lao Zhang's **, a lot of forensic science-related knowledge came out of his mouth, he pretended not to find Lao Zhang's intentions, but calmly walked to Lao Zhang's side, staring at the model in his hand.

"This is the mold I finally extracted from the wound, na, look at it." Lao Zhang handed the model to Yang Zi as if offering a treasure, and he stood beside Yang Zi as if he had mastered some shocking secret, smiling proudly.

This model is only 4.5 centimeters long, thin less than 0.5 centimeters thick, it is not surprising elsewhere, that is, the blade is more complicated, and there are two states at the incision of the model, according to past experience, this knife is narrow in front and wide in the back, and has serrated teeth, the wound to the human body is both smooth and tearing, and these two wounds interact with each other, making the wound look bloody and blurred.

After thinking about it for a long time, Yang Zi couldn't think of any daggers and military slashes that he knew that matched this characteristic, he looked at the model in his hand over and over again, and really couldn't figure out what kind of knife it was.

Seeing that Yang Zi was about to see the model as a flower but got nothing, Lao Zhang couldn't help laughing, he snatched the model from Yang Zi's hand, carefully put it away, and then winked at Yang Zi playfully: "How is it?" Do you see the doorway? ”

Yang Zi was still thinking about what kind of knives this model was similar to, his mind was completely focused on this, and he didn't notice that Lao Zhang was making fun of him, and even threw the idea that Lao Zhang was going to test him to the clouds, and when he heard Lao Zhang talking, Yang Zi replied without raising his head: "It's strange, it doesn't match the number in my impression, and I haven't seen what it is." ”

"Don't think about it anymore, this one is homemade, I roughly estimated, it should be cut and polished with a hacksaw blade." Lao Zhang noticed that Yang Zi was completely obsessed, and he didn't want to tease him anymore, so he told him the answer straightforwardly.

"Hacksaw blades? Can this be done? This was beyond Yang Zi's expectations, which made him ask rhetorically.

"Well, a lot of special-purpose hacksaw blades are very hard, the steel is very good, and if you sharpen it, you can get a good knife." Lao Zhang told Yang Zi with a serious face.

Then he said: "But I think the one used by the murderer to commit the crime is rough and rough, and the shape must be ugly, but before committing the crime, the murderer used to sharpen this knife very sharply, and a certain amount of brute force was used when killing people, so that the wound of the deceased will be made like this." ”

Yang Zi nodded thoughtfully: "So, the murderer may be someone who has easy access to this kind of tool?" So that he could make it enough to make such a sharp knife for himself? ”

"It should be so, you can pay more attention in this direction, I guess the murderer should be the type of person who works on the construction site." Lao Zhang began to fiddle with the various reagents in front of him again.

"In addition, Yang Zi, look, this is a blood sample I extracted, the deceased had signs of taking a lot of drugs before his death, I paid attention to it, there was residual crystal powder in his nostrils, and there was no pinhole in his arm, indicating that his drug addiction was not serious enough to rely on injections." Lao Zhang lit up the test tube in his hand in front of Yang Zi's eyes and told him the results of his discovery.

"By the way, Lao Zhang, are there any other drug residues in his body besides Haloine?" Yang Zi remembered what Robin told him, and hurriedly asked Lao Zhang.

Lao Zhang shook his head and said to Yang Zi: "I didn't pay attention to this, but it shouldn't be, the only thing that can be detected in his blood sample is Hailuoyin." ”

According to the clues provided by Aunt Pan of the neighborhood committee, Yang Zi took Haizi to Qinghe Street, ready to find the construction site where the engineering team led by Wang Yafei before his death was located.

Qinghe Street is close to the S city bus station, which has been under continuous construction in the past two years, and the municipal government is ready to build several large-scale wholesale markets in this automobile transportation distribution center, taking advantage of the large flow of people and convenient transportation of the bus station to establish the Qinghe commercial wholesale business district.

The construction sites under construction in this area are one after another, coupled with the complex environment brought about by its geographical location, Yang Zi and they searched for a day, but they didn't ask anyone at the construction site who knew Wang Yafei.

Seeing that a Qinghe street was all gone, but still found nothing, at this moment, Yang Zi patted his head, since the murder weapon was related to the saw blade, could it be that the engineering team led by Wang Yafei was specially decorated for people? They turned around and walked into Qinghe Street again, this time aiming at the building whose frame structure of the exterior wall had been completed and was being installed and decorated.

Sure enough, on the side near the bus station, there is a Foreland shopping plaza, which is being renovated, the hall on the first floor is full of various decorative materials, the most piled up is wood, several carpenters are cutting and decomposing the wood, seeing Yang Zi take out Wang Yafei's simulated portrait, these workers have stopped their work, surrounded them, and said while looking carefully: "Hey, isn't this Xiao Wang's boss?" ”

Their voices had a strong local accent in them, which sounded the same, but fortunately, Yang Zi was able to understand what they were saying, and after adding gestures, he was able to communicate with them, and one of the workers surnamed Tian was like a small foreman, and he told the other workers to go back to their respective places to work, and he talked to Yang Zi.

He told Yang Zi that Wang Yafei and they were fellow villagers, he came out to work for a few years, entered the decoration industry, learned some skills, and learned some skills, he learned from others to take over the project, and then returned to his hometown to bring more than ten fellow villagers out, and set up a decoration engineering team, because they do the work fast and good, so there are often old customers to introduce new customers, and the decoration project can not be completed singlely.

Wang Yafei is good to the workers, does not owe wages, is kind and kind, usually buys cigarettes and alcohol for the workers every once in a while, and takes his brothers to the restaurant to improve their lives, so everyone is willing to follow him.

The worker surnamed Tian suddenly sighed: "Alas, it's a pity that Boss Xiao Wang didn't take the right path, I don't know how he became addicted to drugs, after he took drugs, he didn't do things very well, no, after the project here was taken over, he didn't come to see it a few times, basically threw everything to me." ”

He shook his head, his face suddenly turned red, and he said to Yang Zi a little twisted: "I don't want to do this either, but the brothers all have several mouths on their knees to eat and drink, and Boss Xiao Wang is always like this, so the brothers pushed me out and asked me to come forward to take over some projects for everyone to do, as for Boss Xiao Wang, we have to say sorry." ”

Tian Foreman didn't know that Yang Zi was here to investigate the murder of Wang Yafei, he thought that Yang Zi was Wang Yafei's friend, in order not to attract attention, Yang Zi pretended that he was here to find Wang Yafei to do something, and didn't explain too much to Foreman Tian.

Finally, after Foreman Tian finished speaking, Yang Zi said: "I mainly want to know about Boss Wang's whereabouts a few days ago, and who people he usually is with?" ”

Tian Foreman thought for a moment, and shouted to a corner inside: "Liu Laosan, you come out." ”

With his shout, a person answered, slowly walked over from that side, Yang Zi saw that this person seemed to have a little disabled on one foot, a little lame when walking, the upper body seemed longer than the lower body, and the two hands were flicked around because of the walking posture.

After a short journey, this person walked for a long time before he walked in front of Yang Zi, and he didn't look at them, stared directly at the foreman Tian, and said vaguely: "What's the matter?" ”

Foreman Tian didn't care about his appearance, and asked to himself: "Didn't Gang Wazi like to play behind Boss Wang's ass some time ago?" And now what about others? ”

The man named Liu Laosan said sullenly: "Gang Wazi said three days ago that he went to Boss Xiao Wang's house, and brought one of his cousins, saying that he wanted to find Boss Xiao Wang to help his cousin find a job, and then Gang Wazi came back, his cousin did not come back, and today Gang Wazi said that he had a headache and did not come to do work." ”

Tian foreman waved his hand, let Liu Laosan go back to work, turned his head to look at Yang Zi and said: "In the past, we all liked to go to the house rented by Boss Xiao Wang to play, play cards and fight landlords, and sometimes drink some wine and brag, but later after Boss Xiao Wang started to take drugs, everyone didn't go much anymore, but this Gang Baby still likes to follow Boss Wang, they are cousins, and they are not taboo about those things at all." ”

Probably seeing that Yang Zi was not like a bad person, and mistakenly thinking that he was here to talk to Boss Xiao Wang, Tian Foreman took the initiative to tell him that they usually live in Banbianpo, rent a few houses there, and everyone lives together, if Yang Zi needs to find Gangwazi, he should be able to find it there.
