Let you condolences to the task force, have you solved the case?

As Lu Chenyao opened the exquisite box, there was a beautiful crystal necklace inside. Although the necklace was not expensive, it was carefully selected by Su Mu through its unique craftsmanship and shape.

"It's a good look." Lu Chenyao said in surprise again.

"Su Mu, did you go out early in the morning to buy this necklace?" Grandma Lu asked Su Mu unexpectedly.

"I don't know what Chen Yao likes. I went to several stores in Jiangbin City before I bought this." Su Mu said with a relaxed smile.

Grandma Lu and the three of them glanced at each other and nodded. Although Su Mu said it easily, looking at the sweat on his face, he knew that he must have traveled a lot.

"Can I eat now? If I don't eat anymore, my stomach can't take it anymore!" Seeing Lu Chenyao playing with the necklace very fondly, Grandpa Duan couldn't help saying.

Lu Chenyao smiled, put away the gift, and asked the waiter to start serving the dishes!

Chapter 251

"Jiangbin City Research Institute".

This is an ordinary plaque, hanging outside the courtyard of an ordinary two-story building, it seems to mean a scientific research institution.

The plaque is relatively new, obviously it hasn't been up for a few years.

If you pay attention, you will know that this research institute has only been listed for three years. No citizen knows what is going on inside, and it is quiet all day long.

The research institute is only a wall away from the armed police squadron stationed in Jiangbin City, and the armed police stationed on guard will have a panoramic view of the second floor of the building.

But even these armed police don't know what the people in the small building are doing.

Although they were curious, no one inquired about the situation of the small building, because every comrade of the armed police who had just joined here would receive an order not to let people approach the small building when they were on guard on weekdays, and at the same time not to ask each other about anything about the small building.

The longest captain of the armed police was Tong Jian. When he was transferred from other places, he was surprised to find that the Jiangbin City Armed Police Squadron had 80 to [-] people.

And other similar county and city-level establishments have no more than 30 people.

After the handover with the previous captain was completed, he realized that he had 80 people under his command, no matter what happened, half of them had to stay in the squadron.

This is an order that, if violated, will be punished by military law.

This morning, Xiao Li, the armed police who were standing guard, handed over to those who were on duty last night, and then they came out and began to patrol around the small building. This is also one of the daily tasks of the armed police squadron.

When they patrolled to the door of the small building, they suddenly heard a piercing sound from inside the small building, as if someone was screaming.

Xiao Li and the others were shocked, but they didn't go in, because they had been specially instructed not to enter the small building casually since they arrived here.

While panicking, a man in a camouflage uniform with no logo ran out from the small building.

The man looked in his thirties, when he saw Xiao Li and others outside.Immediately said in a deep voice: "Let your Captain Tong come over!"

The man was not angry and pretentious, which made Xiao Li dare not refuse to listen. He hurried back and called Tong Jian to come over.

When Tong Jian came, the man just said, "Come in with me."

Tong Jian had no choice but to follow the man in.

Not long after, Tong Jian came out, but his face was very ugly. He said to Xiao Li, "Let Tang Yang, the deputy captain who was on duty last night, come over."

Tang Yang came over after a while, and Tong Jian immediately took him into the small building again.

Time passed slowly, and half an hour later, Tong Jian came out again; "Call all the comrades on duty last night!"

Xiao Li had no choice but to go back and call the comrades who were on duty last night.

When the six comrades on duty last night followed Tong Jian in, Xiao Li and the others became anxious because they found that the reason why the man called Tong Jian over was just to pass on a message.

What he really wanted to find was the staff on duty last night.

"What happened last night?" Xiao Li and the others glanced at each other. Although they were full of doubts, they didn't dare to ask each other.

After Tong Jian and the staff on duty went in last night, they didn't come out again. As time passed, Xiao Li and others became more at a loss.

At this moment, a police car drove over quietly and stopped in front of the small building.

Xiao Li knew the leader of the team, and it was Fang Haotian, the chief of the Jiangbin Police Department.

At this time, Fang Haotian had a serious expression on his face. He got out of the car and walked directly into the small building. Two leaders of the police station came with him, but these two leaders did not go in. Instead, they got out of the car and stood in full armor on duty at the door.

Xiao Li couldn't help clicking his tongue secretly when he saw it, what is the origin of this small building?Even the armed police and the police station paid so much attention to it.

After a while, a car drove out of the courtyard of the small building, and Xiao Li found an old man with gray hair in the back seat of the car leaning on the back of the chair in pain.

There were also three big men in camouflage uniforms and a man in a white coat who looked like a doctor in the car.

After the car drove out, it drove away quickly, and then the man who came out just now, Fang Haotian and Tong Jian all came out.

But the comrades on duty last night were still missing, as if they were left in the small building.

"Really don't let our technicians come over for inspection?" Fang Haotian asked the man with a frown after he came out.

The man shook his head: "The provincial department has already sent someone over, you just need to send someone who is familiar with the terrain of Jiangbin City."

When Fang Haotian heard this, he could only nod his head.

The man turned his head and said to Tong Jian: "From now on, your squadron must closely monitor and not relax at all."

Tong Jian also nodded in agreement.

The man nodded, didn't even say hello to the two, turned around and entered the small building again.

After seeing the man go in, Fang Haotian and Tong Jian looked at each other and smiled wryly.

"Deputy Bureau Zhao." Fang Haotian called out Zhao Qiang, who came with him, "Let Su Mu come here. He is familiar with the terrain of Jiangbin City and is good at investigating and solving crimes. He is needed this time."

"Su Mu is on vacation." Zhao Qiang said hurriedly.

Only then did Fang Haotian come to his senses, and patted his forehead: "Vacation? I forgot about this, and I approved it that day. Forget it, immediately notify him to cancel the vacation and come to help. This matter cannot be delayed."

Zhao Qiang gave a wry smile, and thought to himself, at the beginning, you said that even if something big happened one day, you would guarantee that Su Mu would take a normal vacation, so you changed your mind now?

However, he saw that the atmosphere in the small building was not right, so he took out his mobile phone and called Su Mu.

The soma was sleeping at home, and after being woken up by Zhao Qiang's call, he immediately connected.

When Zhao Qiang conveyed Fang Haotian's intention to him and asked him to come to the small building immediately, Su Mu reluctantly agreed, hung up the phone, and muttered while putting on his clothes: "None of these leaders keep their word!"

After washing in a hurry, in order to hurry, he took a taxi and went straight to the small building next to the armed police station.

When there were more than 1000 meters away from the small building, the driver told Su Mu that the road ahead was closed and he could only get off here.

Su Mu looked up, and sure enough, he found a few traffic policemen pulling the cordon to prevent vehicles and pedestrians from approaching.

"What happened?" Su Mu's heart skipped a beat when he saw the police station's posture.

"I don't know. The road was closed in the morning, and vehicles and pedestrians are not allowed to pass." The driver replied.

"Good guy, look at this battle, what happened is not trivial!" Su Mu asked the driver to wait for a while, and he came to the traffic policemen to explain the situation.

Unexpectedly, one of the traffic policemen knew Su Mu, and hurriedly said: "Zhao Bureau has notified us, Su Suo, I will send you there."

The traffic policeman immediately asked Su Mu to get into his police car.

Seeing that the time was urgent, Su Mu asked another traffic policeman to pay the fare, got in the police car and went straight to the small building.

When Su Mu came to the small building, he saw several police cars parked in front of the small building, including two police cars starting with A.

"The provincial department is also here? It's really a big deal!" Su Mu couldn't help muttering after getting out of the car.

Chapter 252

When Su Mu got out of the car, Fang Haotian saw him and immediately waved his hand to signal him to go over.

Su Mu walked over, Fang Haotian led him into the small building without saying a word.

After entering, Su Mu found that there were two strong men in camouflage uniforms guarding the stairs on the second floor. Both of them had weapons in their hands, and no one was allowed to enter or exit.

"Tell the caravan, please, that the person he wants is here." Fang Haotian said to the two strong guards.

One of them looked at Su Mu and said something to the intercom over his shoulder, and the other party immediately said, "Let him in."

The big man turned his head to signal Su Mu to go upstairs, but he didn't let Fang Haotian in.

"You go up to find the caravan, follow his orders, and be careful." Fang Haotian told Su Mu, and then exited the small building.

Su Mu went up the stairs to the second floor, and the first thing he saw was a living room, which was very spacious, with a coffee table and a set of sofas.

Further into the living room is a curtain that has been pulled open, and inside is a small dining room.

The left hand on the second floor is the kitchen, and the right hand is the room. Counting Su Mu, there are several rooms. At this time, someone is talking in the third room.

Su Mu came to the third room along the corridor and found more than a dozen people inside, three of them were wearing police uniforms, two of them had gray hair, and the other was younger.

The three of them were flipping through the documents at hand, when Su Mu glanced at them, he found that it was an inquiry transcript.

There were seven people standing opposite the three of them, three of them were wearing thick glasses with blank faces, the others looked like cooks and cleaners, and the last one was a doctor in a white coat.

Hearing the sound of footsteps, everyone turned their heads to look at Su Mu, and Su Mu could only ask, "Is the caravan here? I am Su Mu, a policeman from Jiangbin City, and I am here to report."

As soon as they heard that Su Mu was a Jiangbin City policeman, the three people from the Provincial Department turned their heads and continued to read the interrogation transcript in their hands, and ignored Su Mu.

A man in his thirties standing at the door looked Su Mu up and down, and asked suspiciously, "Fang Haotian asked you to come and help?"

After listening to the other party's words, Su Mu knew that he should be the caravan, so he nodded immediately: "Yes."

The caravan frowned again, but didn't say anything, just said: "You go to the living room and wait, I will call you if something happens."

Su Mu had no choice but to leave the room. When he left the room, he heard a noise in the fourth room next door, and he stretched his head to look out of curiosity.

Seeing this, he couldn't help being startled, and saw a dead body lying on the floor of the room, and several technicians seemed to be investigating.

"Someone is still dead?" Su Mu didn't look much, went to the living room, sat on the sofa and thought.

"I don't know who the dead person is in the research institute? There is such a big fight!" Su Mu thought for a while, and couldn't help shaking his head.

Neither the caravan nor the people from the provincial department had the intention of letting themselves or the Jiangbin City Bureau intervene in this case. Obviously, in their hearts, the Jiangbin City Police Department could not help.

As for asking me to come, it's just because I know Jiangbin City well. If it involves relevant matters, I'd better ask in time.

Su Mu leaned on the sofa and looked around boredly, when there was a sound of chaotic footsteps, several people came from the room to the living room.

With a glance, Su Mu found that they were exactly the seven people who were questioned by the three people from the provincial department.

At this time, the faces of the seven people were very ugly. When they saw Su Mu sitting in the living room, they were slightly startled, but they didn't speak. The seven people either sat or stood in the living room.

Facing the seven strangers, Su Mu sat very calmly, observing them from time to time.

Through the clothes and their whispered conversation, Su Mu could see that the three young people with thick glasses among the seven were researchers of the research institute.

Two of the other four are cooks, the other is a cleaner and a doctor.

At this time, the doctor was muttering and complaining in a low voice: "It makes us look like murderers, what's going on?"

Su Mu's heart moved, and he looked through the window to see that the sun was already rising outside. This small building is under closed management, even stricter than the military management.

In addition, there are armed police patrolling every day, as well as caravans and others for protection. Obviously, it is impossible for the murderer to sneak in and kill people, so the provincial department and the caravan suspected that the crime was committed by insiders.

And these seven people are obviously the murder suspects they suspect.

Finding Su Mu looking at him, the doctor snorted and turned his face away.

Su Mu was not angry either, and smiled slightly, still observing them secretly.

I don't know how the provincial department suspected the seven people. According to Su Mu's observation, none of the seven people showed any flaws. It was obvious that they were either deeply scheming or really innocent.

"Come here." When Su Mu was observing, the caravan walked into the living room and said to Su Mu.

Su Mu got up and followed him to the fourth room. At this time, people from the three provincial departments in the next room also came here.

"You contact the local funeral home and ask them to dispose of Secretary Zhou's body." The caravan ordered to Su Mu.

"It turns out that the person who was killed was a secretary!" Su Mu took out his mobile phone and immediately called Zhao Qiang, asking him to notify the funeral home to come and fetch the corpse.

After the phone call, Su Mu saw that the caravan was talking to the people from the provincial department, and he didn't let him leave, so he stayed and listened.

"The whole room is sealed, and outsiders cannot come in. How did Secretary Zhou get killed?" A gray-haired provincial policeman frowned.

"So they didn't have a clue. When Secretary Zhou was killed, the room was sealed? Could it be a secret room murder?"

Su Mu thought in his heart, glanced and found a maroon purple strangle mark on Secretary Zhou's neck, obviously strangled to death by someone, there was no trace of a fight in the room, only a chair was overturned on the ground, Another desk had been moved.

With just a glance, Su Mu immediately concluded that Secretary Zhou was strangled to death from behind while sitting at the desk.

At that time, he was strangled by the neck. Out of instinct, he probably wanted to grab the desk with one hand to resist, and desperately buckled the rope around his neck with the other hand, and finally overturned the chair he was sitting on.

Su Mu tried the walls, doors and windows of the room with his hands. Obviously, the sound insulation effect of this room is good. Even if these big movements happen, the neighbors can't hear them.

"Secretary Zhou died after twelve o'clock, which means that the murderer sneaked into the room at this time. How did he get in?"
