Mr.Cheng, I just want to be your baby

The clouds are big and quiet at night.

In addition, the night before, there was a homicide in the experimental building of the medical college. It was still a student of the college who died. Therefore, the experimental building was temporarily closed. In the evening, let alone no one in the experimental building, there was no one nearby.

Lu Guo stood in front of the sealed experimental building and looked up. Instead of going in immediately, he turned around first.

"How's it going? Did you find anything?"

There was a sudden sound behind him, and Lu Guo turned around.

Zhan Honghui stood behind him about two meters away. Seeing him turn around, he pulled the corner of his lips at him, "do you want one?"

Zhan Honghui took a pack of cigarettes in his hand, smoked one and asked Lu Guo.

Lu Guo nodded.

Zhan Honghui came forward, handed him one, and then polished the lighter.

"Thanks." Lu Guo held the smoke in his mouth, lowered his head, lit the smoke on the fire, took a sip and looked into the distance.

Zhan Honghui also lit a cigarette and puffed up.

After taking two breaths, Zhan Honghui said: "I've observed that every floor of the experimental building is equipped with monitoring. Except for the public toilet, it can be said that other corners are 360 degrees without dead corners. If someone appears in the experimental building during the day, it will definitely be photographed by the probe, but unfortunately, it happened in the evening. The light in the corridor of the experimental building is a voice controlled light. There was movement when he left the laboratory on the first day of the first day , the voice control light was on for a few seconds, and the monitor took pictures of her leaving, but she may have walked very lightly when she came down the stairs and didn't turn on the voice control light on the stairs, so the monitor didn't take pictures of her until she came out of the experimental building. "

"Is there something wrong with the voice control light in the corridor?" Lu Guo said his guess, "I watched the surveillance video. The shoes she wore on her feet last night were small white shoes. The soles were not as soft as sports shoes. She walked normally. If she didn't deliberately lighten her steps, the voice control light would be on. Moreover, she was down the stairs and there was no need to lighten her steps. The sound would be louder than on the level road. It's strange that the voice control light didn't light up."

Zhan Honghui nodded, "Yes, I thought about it, so I went up the stairs and walked back and forth several times. When I went down the stairs normally, the voice control light would be on. Moreover, I asked the floor manager. They would check the voice control light one by one every day, and the broken lights would be replaced in time. He said that when he checked last morning, he found that there were some problems with the lights between the fourth floor and the third floor, which had been replaced with new ones Yes, the rest of the lights are normal. And he keeps a record of when and where the lights are changed every day. I have seen the records. On that day, in addition to the lights on the stairs between the fourth and third floors, he replaced one in the corridor on the sixth floor. "

"Did you find that these lights are replaced frequently?"

"It has been more than 10 years since the completion of the experimental building. The administrator has always been Lao Wu. He is a very considerate person. He has recorded everything he does every day. For more than 10 years, his notebooks are thick. I don't have one by one. I only read those in the last three months. In the past three months, I changed the lights nine times, including five in the public bathroom and the other four, and one was yesterday. Lao Wu told me Tell me, the quality of these voice controlled lights purchased by the school is quite good, and the average life span is 2 to 2.5 years. "

Lu Guo was silent when he heard the speech, but silence doesn't mean he doesn't have a clue at all.

Zhan Honghui looked up at the experimental building and took two puffs of smoke, but then said, "have you asked junior one? The surveillance video shows that when she left the laboratory to lock the door, she seemed to find something and suddenly turned around."

"I didn't ask. She was not very stable." Lu Guo said, pausing for a moment, but said, "but my father said that she felt someone following her when she came home one day, but she didn't see anyone back."

"Felt like someone was following her?"

"That's what my father said."

"This girl, she doesn't tell anyone about such an important thing. She doesn't tell me anything. I asked her if she found anything unusual when she left the experimental building last night. She told me no."

Lu Guo smelled the speech and looked at Zhan Honghui. "You're not her brother. How can she trust you?"

"Why am I not her brother? Are you and I brothers? Is your sister my sister?"

"It's just your wishful thinking. Besides, every time she encounters something, you call the police. Do you think she can make a good impression on you? Even if she knows you and I are brothers, she can't trust you, let alone..."

At this point, Lu Guo didn't talk down.

"What's more?" asked Zhan Honghui.

"Besides, she has two brothers, me and her second brother. Do you think you are redundant?"

Zhan Honghui was very uncomfortable. "Why do I call it redundant? Isn't it good for one more person to love her?"

"Of course, but did you show your brother's love for her sister and let her know?"

"I..."

Zhan Honghui opened his mouth and snorted, "if you say so much, it's mean! You're too possessive. You think I'll take your baby sister away."

"It's true."

Lu Guo smiled and fell into memory.

When she was a child, Yibao asked her that her second brother was not called "second brother", but "brother" as she was called.

In fact, at that time, she didn't have much concept of the "big" and "two" of the big brother and the second brother. She thought that the brother was my brother. You were my brother, and he was also my brother. You were all my brothers, so she called him brother when she saw him and her second brother. When she saw them together, she called them brother respectively.

But he was unhappy because he thought that this "brother" was his exclusive, "her brother" could and could only be him, and no one else could.

But she was too young at that time. Every time he told her to ask her his name was brother and her second brother was second brother. She promised well at that time and forgot as soon as she turned around. There was no way. He had to clean up Lu Ren.

Therefore, Lu Ren didn't get cleaned up less at that time, and it is estimated that Lu Ren doesn't know why he got so much cleaning up when he was a child.

Now think about it, in fact, I was very bad at that time.

It's not good enough. Her latecomers finally realized their own problems, or maybe he kept on explaining. She finally changed her mouth, so the "brother" became his own name.

This should be what Zhan Honghui said about possessiveness, but he didn't understand it at that time.

I really wronged Lu Ren.

Alas!

Lu Guo sighed and remembered that Lu Ren had come back for some time. At that time, Yibao must often stick to him. His brother is expected to be cold.

"By the way, how long will it take to leave from the fourth floor?" Lu Guo suddenly asked.

Zhan Honghui finished his last cigarette and then answered: "From the fourth floor stairway to the first floor, if you follow a person's normal walking speed, it is about 1 minute and 20 seconds. It takes about 20 seconds to walk from the first floor stairway to the exit, a total of about 1 minute and 40 seconds. However, it took three minutes and 10 seconds on the first day of the lunar new year last night, excluding one minute and 40 seconds, and one minute and 30 seconds to kill one in such a short time People can be established in theory. Moreover, if you follow the normal walking route, go down to the first floor and turn left for about 5 meters, and then go straight to the left, you can get to the exit. According to the footprints on the scene, she didn't turn left first when she went down the stairs to the first floor, but came back to the right. Moreover, the footprints on the right were deliberately erased, leaving only the footprints on the right The next two seem to have been omitted and not erased. If there is no murder on the first day of junior high school, then this is an elaborate Bureau. Now all the only evidence points to the first day of junior high school. She is the suspect, and the scene where Shang Linru was killed was seriously damaged, because it was time for students to come to class early to do experiments. "

Lu Guo smelled Yanjun's eyebrow and wrinkled slightly, "so, you mean, I can't help Yibao to clear the suspicion?"

"It's not that there's no way. It's not easy for you to find evidence in favor of junior one."

"As long as it is a person, no matter how careful the game is, there will be loopholes. There is no perfect person in the world, and there is no seamless plan!"

Lu Guo believed that as long as he calmed down, he would be able to find the flaw.

"Do you want to look for evidence with me?"

After smoking a cigarette, Lu Guo threw the cigarette butt on the ground, crushed it with his feet, pinched it and threw it into a nearby trash can and asked Zhan Honghui.

Zhan Honghui shrugged his shoulder. "Otherwise, what am I doing here? I haven't investigated with the captain for many years."

"There are opportunities in the future."

"That's not necessarily true. You're the land bureau now."

"What's the matter with the land bureau? It's just a position."

"Just stimulate me. I've been in the police station for so many years. I haven't even been in a deputy bureau. You're the director now. Do you still let people live?"

Lu Guo raised his eyebrows. "There's no way. The backstage is hard!"

Zhan Honghui snorted and said, "yes, with a background as hard as the president, who else can be as hard as you!"

"If you know, let's go, officer Zhan. Accompany the landing bureau to find the evidence. If the case can be closed within three days, I'll apply to the president for you to be my deputy."

"Really?"

"What do you say?"

Zhan Honghui disdained and said, "who wants to be your deputy? When you were in the army, you wanted to be on my head all your life?"

"So you mean you're going to be a small section chief all your life? Don't you think I'll put pressure on you? So you might as well choose a bigger one, don't you?"

"Don't be complacent, you boy! The case can't be solved in three days, and you're no longer the director. I see you'll fart at that time!"

The reason why Lu Guo dared to let Lu Chuyi go home directly was that he promised the president that there were two.

First, he promised that Lu Chuyi was innocent and would never kill anyone.

Second, he promised to solve the case within three days and catch the murderer.

If the case cannot be solved within three days and the murderer cannot be caught, Lu Chuyi will not only be locked up for interrogation again, but he will also be dismissed.

Lu Guo doesn't think so. For him, it has been a long time for three days. He can do a lot of things for 72 hours in three days.

Moreover, the timing is at 11 o'clock tonight, that is, it's one hour ahead of schedule. He has 73 hours. He's afraid he can't solve the case?

Entering the experimental building, Lu Guo didn't rush to the scene to check. Instead, he first walked around the hall on the first floor, then went up to the second floor, the third floor and the fourth floor without stopping. He continued up to the fifth floor, the sixth floor and the eighth floor.

The experimental building has eight floors. After arriving at the eighth floor, Lu Guo went to the roof again.

Standing on the rooftop, he asked Zhan Honghui, "have you ever been here?"

"No."

"Do you think there is any doubt here?"

Zhan Honghui looked around and his eyes fell on the building next to the experimental building. The distance between the two buildings is only about 5 meters. If there is a cableway, it is easy to go from the experimental building to another building. 5 meters is not far at all.

"All the people who entered the experimental building can find the time to leave in the monitoring. On the contrary, all the people who left can also find the time to enter the experimental building on the same day. I calculated that there were 305 person times, which is not a lot. But among these people, only Shang Linru didn't have the entry and exit records, but she appeared in the building and died in the building. Don't you think it's strange "Did this man appear out of thin air?"

"You mean..."

Zhan Honghui stared at the neighboring building with a surprised face. For a full minute, he turned back and looked straight at Lu Guo and stretched out his thumb, which was sincere admiration.

He thought he had checked all the doubts and there were no problems in all places, but he ignored the roof and all the people entering and leaving the experimental building.

"Captain, it seems that you have made preparations in advance before you come."

Lu Guo hooked his lower lip. "Before you came, I went to the building opposite. The building administrator told me that the roof was locked on weekdays, but when he patrolled the building this morning, he found that the door lock was actually open. He didn't care. He thought it was another administrator. He forgot to lock the door when he went to the roof during his rest yesterday, so he locked the door again. I went to the roof to see it."

"What did you find?"

"There are footprints of at least three people. One of them has the same shoe size as Shang Linru, but it is not sure that it is Shang Linru."

Zhan Honghui was silent. He felt that he was wasting his time and resources in the criminal investigation department for so many years.

For a long time, Zhan Honghui said, "Captain, why don't I be your assistant in the future? I'm not the section chief anymore."

Lu glanced at him. "Why?"

"Learn from you! I don't think I'm fit to stay in the criminal investigation department."

"Then you have to think about it. Being an assistant to the land bureau is not as beautiful as your section chief."

"The case can't be solved. What scenery do I want!"

"Say it again!"

Lu Guo walked on the rooftop with a flashlight and observed it. As he thought, the footprints on it were treated cleanly, leaving no trace.

But

Lu Guo's flashlight fell on an irregular circular hole on the roof railing, and there were scratches around the hole.

"Come and see what this is."

Zhan Honghui stepped forward, his eyes stagnated, and then exclaimed: "how professional!"
