Ace continued to ask the foreman. "Can anyone prove it?"

Boss Fan came out to speak at this time. "I can attest to the fact that I didn't have time to pick up my wife on Saturday night, so I asked him to pick him up."

The boss came out to prove to them, the ace is gone, the ace and Jinshan both know, now his shoes are a bit inappropriate, the shoes worn by people are not the same pair, and each style of shoes will be different, the average consumer bought two styles of shoes, if the yardage difference is one yard is also okay to wear, now the bag foreman's shoes are Nike, not the scene of leather shoes, if the murderer is him, the general shoe print can be identified as the same as him, if he insists that he has not been to the factory, There is no way to take him.

However, the words of the foreman made the ace pay attention, because there was a woman's shoe print at the scene, and the shoe print is a brand-name shoe, if so, then she is in line with the person who came to the scene, so it is right, and it is also on the spot, and now it is necessary to find out when the foreman went to pick up the boss's wife, and whether they have the possibility of returning to the construction site.

Ace continued to ask the foreman. "What time did you leave the construction site, and what time did you send the boss lady back?"

The foreman replied to the ace. "I'll leave at seven o'clock and send the proprietress back at twelve o'clock in the evening."

Boss Fan followed to prove this. "Yes, yes, my wife didn't go back until twelve o'clock, and she was drunk like mud."

Ace whispered to Jin Shan. "That is to say, they have five hours in between, and it is entirely possible to come back, but how did they kill the construction workers in front of so many workers and not be discovered, and if so, the construction workers did not send the cement slurry to the construction site, and the people above found out, but they did not know it."

Jin Shan also thought of a little. "Could it be that the workers were no longer using cement slurry at that time, or that the murderer was working instead of the construction workers, and no one would pay attention to whether the people below were the builders themselves?"

Ace asked the workers. "I ask you what you found that night, that is, what unusual behavior of the construction workers, or what unwarranted things happened on the construction site that day."

Workers, you look at me, I look at you, I don't know what the problem is, and I can't remember what the problem is, and at this moment, a worker spoke. "Comrade policeman, when you say this, I think of one thing, we got off work at ten o'clock that night, and the weather forecast said that it would rain at night, after we used up the cement slurry in the mud truck, it was nine forty-five, we were afraid of rain, so we left work fifteen minutes early, and the construction worker left work on time, he packed up the tools in the back, we left early, and the construction worker had to sort out things in the back before leaving."

Ace asked about the workers. "In other words, after you leave, even if someone comes, you won't know."

The worker replied trump card. "If someone comes we won't know, we will go out of the factory as soon as we get off work, the contractor is too careful, we live in the tin shed, but on a hot day, the boss paid him to arrange to help me install air conditioning, he didn't install air conditioning, even if he didn't install air conditioning, he didn't give us a bigger fan, a broken fan was there, and we had to deduct more than 100 yuan a month for utilities, we reacted to the boss, and then we all moved out to live, and the door was closed when we went out, and people without keys couldn't get in here, Not to mention killing people inside. ”

When the contractor heard this, he scolded the worker. "You are talking nonsense, now the electricity bill is so expensive, the water bill is also expensive, I will yell there after deducting a little bit, the air conditioner, the boss only has a few dollars from me, the air conditioner can't afford it, how to install it."

Boss Fan also appeared this time. "I didn't handle this matter well, I will definitely deal with this problem, this problem happened in the past few days, and there is no time to solve the problem, so that the inspector will laugh."

Ace looked at them and said. "Your family affairs have nothing to do with me, that is, after you get off work, there will be only one construction worker left, and he will leave when the time comes, so the murderer will also kill during this time period."

The worker continued to answer the trump card. "Yes, when we left, we pulled the main gate, and it was dark after the construction site, and the construction worker had a flashlight in his hand, and he would leave the site after he finished dealing with it."

When the ace heard this, he walked back and forth and analyzed. "At that time, the electric gate was turned off at the scene, if it was a thief who came in over the wall to steal something, they would not choose to steal there, it must be looking for valuables to steal, and if the thief came in and was found by the construction worker, the thief was afraid that the matter would be exposed, and he could run away after the killing, why did he have to bury the body, so this is not a thief, since it is not a thief, the workers leave the construction site, and the door is locked, so who can come in, the workers can come back, yes, but the shoe prints on the site are not left by the workers, Even if the worker comes back to steal something, he can wait for the construction worker to leave and come in, the purpose of his coming in is to make money and not to kill him, so he will not kill the construction worker, then the only possibility is that the contractor came back here that night, how do you explain the contractor. ”

The foreman immediately sweated when he heard this, because the police suspected that he was coming, and he replied hesitantly. "I've been back, but it's one o'clock in the night."

The ace replied to the foreman. "It's good that you came back at one o'clock, but you came back when the workers got off work, and as for how you killed the construction worker, it must have been the construction that saw something unsightly about you, which caused you to kill him, kill and abandon the body, and send the boss back to the scene."

The foreman pointed to the trump card. "You are talking nonsense, I was with the proprietress that night, and the proprietress can testify for me."

Ace looked at the foreman and said with a smile. "She testified for you, and it was also a false testimony, because there were women's shoe prints at the scene, and I tell you, eighty percent of the shoe prints were hers."

Boss Fan was stunned when he heard this scene, since the murder was related to his wife, this time it was troublesome, the workers were not surprised to see this situation, I wish the contractor was the murderer, but it was a pity that the construction worker was such a good person.

The foreman of the contract continued to answer the trump card. "You talk nonsense, you say that I have evidence for murder."

Ace looked at the foreman and said. "Proof, I have, you go to his room and bring me all his shoes."

When the workers heard the ace tell them to go and get the shoes of the foreman, they all went to get the shoes, and the foreman said to the ace. "You are trespassing on a private house, and if you go without my permission, I will sue you."
