Zhou Wang said: "The murderer knows about the Lin family and is on a business trip, which means that the murderer has been in contact with Shi Yufen recently, not the kind that has not appeared suddenly for a long time, of course, it appeared suddenly on the night of the crime, I mean ......"

"I understand!" Wang Qin said: "The murderer needs to have the conditions to often enter and exit the villa area, at least during this time, the time when he has an adulterous relationship with Shi Yufen can, maybe it is the access card that Shi Yufen gave him, which makes it very convenient for him." ”

"The second point is that the murderer did not drive into the villa area!" Zhou Wang said.

"Yes, don't say about twelve o'clock in the surveillance, we have watched the surveillance from eight o'clock in the evening to five o'clock in the morning, and the security guard confirmed that no non-owner vehicles entered, except for fire trucks and police cars."

"But this can't investigate the possibility that the murderer waited in the villa area early and waited for a long time before leaving after the crime." Liu Bing said.

"If that's the case, he doesn't need to go to Shi Yufen in his twelve, as long as the child sleeps, he can go, and the two should be able to communicate, but the murderer in this case doesn't seem to have communicated with the deceased." Zhou Wang's answer.

Liu Bing sighed in frustration.

Dalong said with a smile: "You said that I have a good education, did you also leave the serious case brigade?" This brain ......"

"What's useful in your doctor's brain?" Liu Bing asked through gritted teeth.

"If the murderer has a community access control card, it is really difficult to find, but you have forgotten a very important key point, the villa area is on the edge of the city, there is no bus to arrive, if the murderer does not drive, he can only take a taxi, or drive the car to the neighborhood, get off and walk to the villa area, is it necessary to check the monitoring and taxis of the surrounding roads?" Dalong asked proudly.

The office was quiet for a moment, and Dalong raised his eyebrows at Liu Bing.

Wang Qin began to pace around the office, analyzing as he paced:

"The murderer knew that Lin Jiahe was on a business trip and parked the car outside the community, which shows that he was going to kill Shi Yufen, but judging from the scene, he should have made a temporary decision, otherwise he would definitely understand what time Lin Jiahe would come back in advance, and he would not appear after twelve o'clock."

Liu Bing glanced at Dalong and snorted coldly.

Wang Qin also said:

"If the murderer came by taxi, then how can he leave after killing someone? It's not good to take a taxi in the middle of the night, he came for a purpose, he got the things, and he couldn't get a taxi for a while in the middle of the night...... Besides, doesn't he need to confirm Lin Jiahe's itinerary before he comes? Lin Jiahe has worn so many green hats, and he will definitely not tell Shi Yufen that he is sure when he will return one day on a business trip, and Shi Yufen will also keep an eye on it, this kind of competition, they are not a day or two. ”

"Don't walk, I'm dizzy!" Zhou Wang rubbed his eyes: "From the perspective of time, no matter which direction the murderer came from, it is impossible for him not to ask the Lin family and the time when he will go home, even if he is already halfway there, Shi Yufen will immediately tell him when he receives Lin Jiahe's information, so the murderer still has one condition......

Zhou Wang looked up at Wang Qin.

Wang Qin's eyes widened wider and wider, and then he burst out: "The murderer doesn't need to know from Shi Yufen when the Lin family will come back!" ”

"What?" Xiao Shang, Da Long, Liu Bing, all spoke in unison.

"We were all led astray by Shi Yufen's previous lover." Zhou Wang stood up and walked towards the door of the office.

Dalong was anxious: "Why are you doing this...... What's missing from below? Explain it clearly! ”

Zhou Wang turned his head and said, "Think with your brain!" Don't delay their work. ”

Wang Qin turned his head to Xiao Shang and Liu Bing and said: "Contact the property management company in the villa area immediately, and find all the security guards who were not on duty on the night of the crime but lived in the dormitory of the community!" ”

"Security?!" Dalong exclaimed, then took a deep breath and said clearly: "That's right! Forget about this waterfront building. ”

Xiao Shang also understood and said:

"Shi Yufen has been looking for lovers since she arrived in Yangjiang, and the lovers she is looking for are still of a certain level, either technicians, doctors, or they have bought a house and become a family, giving people a feeling of disliking the poor and loving the rich, we didn't think about the security guard, it's normal."

Liu Bing hurriedly said: "This makes sense, why he was busy for three hours and was not afraid, because he knew what his colleagues were doing during that time, and no one would patrol!" ”

Dalong was just about to express his respect for Zhou Wang, but Zhou Wang had already pushed the door and left.

Dalong chased out: "Why are you in a hurry? ”

"When I go to the bathroom, you follow?"

"No, I haven't ordered takeout today, what time is it!"

"You get off work quickly, we won't need us for the time being."

……

The next day, as soon as Zhou Wang pushed open the door of the office, Dalong greeted him and said, "It's really a security guard!" One of their security guards resigned the day after the incident. ”

"Resign and leave is the murderer?"

"Caught overnight! It's what village is called the west side of our Yangjiang River, anyway, it's not far, it's only more than an hour to come and go......"

"Getting to the point!"

"The point is that Wang Qin and they interrogated the security guards overnight, and at first the security guards didn't admit anything, and then they heard that there were biological samples remaining in the deceased's body, and he needed to cooperate with the inspection and comparison, so he admitted to having an affair with Wu Yufen, but he didn't admit anything else, as if he knew that the police had no evidence."

Zhou Wang frowned and asked, "On the night of the crime, no one in the dormitory found out that he was not there?" ”

"No, I knew it was on fire, and the people in the dormitory ran out to see the fire together, and he was there at that time."

"He didn't find anything useful in his house? He must have found something in the study. Zhou Wang asked.

"Now I don't know what the murderer took from the study, it's good for them to bring people back overnight, Wang Qin and they are tired and now they are hibernating collectively in the office."

"How do you know so well?"

"I was busy with them yesterday, and I followed them for about an hour after you went to the bathroom, and I followed them throughout the interrogation."

Zhou Wang patted Dalong and said, "You also lie on the table and squint for a while, and get off work early today." ”

"I slept for a while, Niu Lao came and left in a hurry, I woke up, now the headache is that we have no evidence to prove that the murderer is a security guard, I thought a lot, is it possible, the murderer is really not him, but someone else? He left after having a relationship with Shi Yufen, and then someone came, and as soon as he saw what was wrong, he quickly resigned and went home. ”

"Their property company is so free? Said you can leave on the day of your resignation? Zhou Wang asked.

"That's not it, Wang Qin asked the director of the property company, and the director of the property company said that the security guard submitted his resignation letter more than a month ago, because he couldn't find anyone to replace him, so he stayed for a few more days, their salary is really low, and it is better to find a job elsewhere than this, but it is really comfortable, you don't have to do anything, you don't have to care about anything......

"Let's go to the villa area again!" Zhou Wang turned around and left.

"Do you have an idea? Let's talk about it. Dalong followed him out of the office.

"You've got a survey box with you." Zhou Wang stood at the door, and Dalong went back to get it.
