Ace listened to this clue and determined that the deceased was a construction worker, he wrote down some information about the construction worker and left the Wangzai Group, dialed Zhou Ling's phone on the road, and asked Zhou Ling to prepare to extract the DNA of the construction worker's family for identification, and identify who the deceased was on the spot, and the identity of the deceased could be confirmed when the identification results came out.

Ace went to the builder's house according to the address on the information, and the builder's parents were anxiously looking for him, and when Ace went to his house, he didn't dare to tell him that his son might be dead, because the builder was their only child, so he said that he was dead, it wasn't that they were in pain, Ace could only take one step at a time, and go to his house to show his identity, and the old man was also worthy of Ace, and mentioned their DNA, Ace just said that this would help them find their son, of course, it couldn't be said that it would be taken to identify with the deceased, if it did, They will also be suspicious, no matter what, they can hide it for a while.

Zhou Ling identified the DNA of the deceased with the DNA of the construction worker's parents, and the result was that the deceased was a construction worker.

After the ace confirmed the identity of the deceased, he now had to go to his parents to understand the situation, but he was afraid that they would not be able to accept this fact, after all, the old man's health was not good, and the ace called a doctor to follow him, preventing the old man from being unable to accept the stimulation, or fainting.

Sure enough, as Ace thought, he told their parents the news of the death of the construction worker, and the two old men fainted on the spot, and Ace took the doctor to send them to the hospital immediately, Ace had no way to find out the news from the parents of the deceased, so he could only ask the village chief, and Ace also learned some biographical information about the construction worker from the village chief, the construction worker has nothing to say, he is honest and diligent, he is responsible, he does not smoke, he does not drink, he does not gamble, and he does not spend money, whether it is in the company, No matter in the village, it is said that this person is very good, working outside, giving the money to his parents as soon as he is paid, and the people in the village are introducing his wife to him, but he has been busy working, making money to his parents, so that they don't work so hard, don't be so tired, go to work on the construction site at the age of eighteen, there are two hundred yuan a day, recently the company launched to work overtime, two hundred a day plus overtime has four hundred days, the construction worker took the initiative to apply to work overtime, although he is a construction worker, the boss also values him, because he is diligent, The company wants to buy anything will ask him to buy, take this period of time, the weather is hot, the boss will pay in the afternoon to buy watermelons for the people on the construction site to eat, are arranged for him to buy, honest never greedy for money, how much money the boss gives, how much watermelon to buy back, in the hot summer, the workers who eat watermelon feel very comfortable, watermelon is the construction site boss specially bought for them to eat.

The boss also asked the construction workers to do some important things, for example, some, the driver pulled the cement to the construction site, and there was usually a list, which was collected by the construction worker for him.

The company's scrap products are all sold by him. Although it could not be sold for a few dollars, the boss gave him the money from selling scrap products, but the construction workers took out the money and shared it with the workers, bought fruits, and distributed them to the workers.

A person that the boss values very much, a person whose co-workers say he is very good, the villagers are vying to introduce him to the person who introduces him, his interpersonal relationship is very good, he has not offended anyone, he has no enmity with anyone, he has no girlfriend, and he will not have emotional disputes with others, so the only possibility is to be robbed and killed, generally murder and robbery, will not bury the body, kill and take away the finances and leave the scene, indicating that the murderer must be someone who the deceased knows, who killed him, after the ace learned of these circumstances, The deceased had no enemies, and he did not offend anyone, so he was burying the body after the killing, which can only indicate that an acquaintance did it, and from the scene, it was inferred that the death of the deceased was likely to be at the construction site, and the ace set his sights on the construction site.

Ace Jinshan non-stop to the construction site, the construction site due to the rain in the past two days, the construction site stopped working, the construction site is the development center of the town, is the real estate development out of the community, in the construction site, several floors of the house without a good construction appeared in the eyes of the ace, there is a temporary house on the construction site, for the workers to live, there is a contract foreman to live, the contract foreman, is the person who leads the workers to start work, but also the boss's red man, every year also gives a lot of red envelopes, the contract foreman is very fragrant, some of the contract foreman will also embezzle the workers' money, This kind of contractor is the heart of a human-faced beast.

For example, if an employee of the company introduces a worker to come in, as long as the company can work for four months, there will be a referral fee of 400 yuan, and the contractor will eat 50 and only give 350.

The workers thought that Ace was here to investigate the contractor, so they told him all the negative news, but they were wrong They came to investigate the murder, because the construction site was suspended, the workers were not at the construction site, and there were several workers in the makeshift house who did not go out shopping, Ace asked them about the situation at that time, the time of death of the construction worker was on Saturday night, that is, when he was about to get off work, Ace learned where the construction worker was working at that time, the construction worker was working on the ground, and he put cement in a mud truck, sand, they mixed up, mixed in the mud truck, put it in the trolley, pushed to the construction site, and hoisted it up with a crane for construction, after knowing these conditions, Jinshan went to the construction worker, where to work?

There is still solidified cement sand in the mud truck, which has been washed, only a little bit is seen on it, the trolley is placed, and the power supply of the mud truck is also unplugged, it can be seen that the construction workers got off work at that time, and the location of the site is at the gate of the construction site, and it is from the gate to come in, but it is behind the temporary iron house, Jinshan Ace saw the footprints of three people next to the mud truck, although there are many footprints, from the size of the pattern is three people, at that time it was also like the workers understood, There is only one person who works hard there for the construction worker, except that he occasionally has a worker who goes to him to leave footprints is normal, but the footprints on the scene are abnormal, and the reason why the footprints are left is because of the mud and sand on the ground, so the ace reasoned about the footprints.

"I think the footprints on the site are wrong, if we deduce that if the footprints were left very early, the construction workers are busy working here, they will definitely be covered by other things, but the footprints on the site are very clear, that is to say, when the footprints were left, the construction workers were not there, so it rained that night, but the rain did not take the footprints away, because when the cement sand footprints went down, it had not solidified, and after they left, after the solidified cement slurry, Rain can't wash away shoe prints at all, so these three shoe prints have a very large appraisal value. ”
