Ningbei County is not too big, with a population of more than 100,000. The location of the credit union is a little northerly north of the center of the county. Although it is not a downtown area, it can be regarded as a place where people come and go.

The site is located in a three-story building. The first floor is the business hall, and the second and third floors are office spaces. There is a gate on both sides of the left and right, and there is a large courtyard inside, which is used as parking cars and other means of transportation.

There is a wall in the middle of the courtyard, which divides the courtyard into two. On the right is the entrance and exit passage for employees to and from get off work. On the left is the forbidden area of ​​the vault. After investigation, there are no traces of climbing in the wall, which eliminates the possibility of criminals entering the case site from the office area. There are also walls on the east and north of the courtyard, and there are still no traces of climbing in the area.

The scene of the case was in the vault duty room. For safety, this place was artificially cut and did not communicate with other office spaces. The vault was located on the third floor, with a separate staircase up and down, and it was an independent existence in its own system.

Since the vault is on the third floor and is set as an inner staircase. If a criminal wants to enter here from the street and wants to get close to the vault, he must first pass through three anti-theft doors and also pass through the passage guarded by two on-duty officers.

The yard door on the left is a stainless steel security door. After the incident, it was found that the security door was locked from the inside, not opened, and there were no signs of climbing or prying. Even if it passed through this security door, it only entered the courtyard. If you want to enter the corridor leading to the vault, you must also pass a "Panpan" security door.

The anti-theft door was opened, and a duty officer died in the door frame. Judging from the situation on the scene, the murderer should have attacked from behind and suddenly covered and pinched the deceased's throat. This not only prevented the duty officer from screaming at the police, but also directly caused the victim to die of mechanical suffocation. It should be said that the murderer Kong Wu is powerful.

Following the stairs in the duty room on the first floor, the duty room on the second floor was also an anti-theft door, which was also not closed and there were no signs of prying and pressing. The second duty officer died on the computer chair in the duty room.

The computer game screen called "Red Alert" is displayed on the computer display screen. The location of the body shows that the deceased was playing games on the computer before being killed. The man was also attacked by a criminal from behind and stabbed his neck with a sharp weapon, causing heavy bleeding to die.

The last anti-theft door on the second floor entered from the duty room on the third floor, which had been pried open by the criminal using tools.

On the ground in front of the vault door, there were two strings of keys scattered. Next to the keyhole of the vault door, you can see the traces of the criminal trying to use the key to open the door. However, the quality of the vault door was indeed a little better, which made the criminal sigh and return without success.

The entire scene was damaged by the criminals and officials, neither fingerprint nor footprint was found. It was a feeling of helplessness when people saw it. Captain Gu only stayed on the scene for two hours.

Facing such a scene, no matter how rich experience is, I have no way to focus. I can only do my best and rely on destiny. "Old Shen, I still have a case in my hand, and I really can't get rid of it. In this way, I will keep Long Ruohai and his group for you and let them help you Ningbei police solve the case."

When Long Ruohaike heard the command of the detachment leader, he was overjoyed and quickly agreed to say, "Okay, okay, okay. Detachment leader, don't worry. "Little Zhuge" and I will definitely work hard under the leadership of Captain Shen."

"Well--Okay." Chen Quanbin was a little disappointed with the arrangement of the detachment captain. He didn't take Long Ruohai and "Little Zhuge" seriously at all. He originally thought that the detachment captain would stay and personally direct the case to solve the case. However, he didn't expect that what could it be for leaving behind such two little guys who had not yet grown up?

He always felt that this so-called "interpol" was about the same as being used to talk to a partner, to be cool, and to coax girls. If it was really used to solve a case, it would be better to rest aside. Not causing trouble for yourself. If I had known this would be the ending, it would be better not to call this call for help.

Chen Quanbin was already full of anger, and of course he would not have a good face for Long Ruohai and "Little Zhuge". He didn't want to receive so many "instructors" from the Municipal Bureau. After the detachment leader left, he said lightly: "Jing Shaohua, you are responsible for receiving the leaders of the Municipal Bureau. If something goes wrong, be careful that I will cause trouble for you."

"Don't worry, don't worry, don't worry. I will definitely arrange the lives of all the leaders." Jing Shaohua, who had just caused trouble, was eager to redeem his sins. In front of Shen Quanbin, he looked like a well-behaved child. Of course, he nodded too late to say yes.

As soon as he finished speaking, Chen Quanbin left. He was anxious to organize internal employees of the credit union to investigate, and of course he didn't have time to accompany these two kids. "Little Zhuge" was not convinced and wanted to catch up and argue. Before he could start, he was stopped by Long Ruohai immediately.

"Why do you want to stop me? He is so cool. If you have the ability, don't ask for help from the detachment. You are a hero. After the detachment leader left, what kind of mighty look like in front of us? What kind of hero!" "Little Zhuge"'s obstruction of Long Ruohai was very angry.

"If you can't solve the case, you're just talking nonsense, so why bother to act irritated? Besides, if you have the energy to quarrel, it's better to go to the scene more often, and you might even find it unexpectedly." Since Gu Zhongtian was leaving, Long Ruohai was appointed to lead the team, and of course, "Little Zhuge" had to only follow Long Ruohai's horse.

When he first heard the detachment captain's arrangement, Long Ruohai couldn't believe his ears. No matter from any angle, it would not be so fast, and there would be a chance to stand alone. Moreover, "Little Zhuge" had a much longer time in the serious case than himself. Even if he acted as a temporary leader, he should be the one who should be.

Gu Zhongtian was indeed without troops, which was the actual situation he didn't know. In the entire detachment, except for Long Ruohai and "Little Zhuge", two young men who were regarded as rude and had already sang the "Empty City Scheme". "Little Zhuge" often went out of tune in his work, so how dare he lead the team?

"This is equal opportunities, I have to work hard." Long Ruohai encouraged himself and took advantage of this rare opportunity to fully demonstrate his abilities and talents. While letting Jing Shaohua lead the way, he came to the crime scene again.

He asked the technicians and Captain Du and others to work together to conduct on-site investigations around the vault again. He hoped to find some unexpected surprises, provide a basis for solving the case and point out the direction. He stood outside the scene and began to observe carefully.

The site is a three-story building. There are also the same buildings on both sides of the left and right, with no passages or windows between each other that can be used by people. The business hall exists separately. After get off work, the only passage connected to the office building is also closed and there is no way to pass. There is a large yard behind and a public toilet is available in the northeast corner of the yard.

Judging from this terrain, there are only two ways for criminals to commit crimes. One is to use a key or call the door to enter the duty place, which is likely to be an internal thief, and solving the case is relatively simple.

Second, entering through the wall of the backyard is much more complicated. Inner thieves, external thieves, locals commit crimes, and traversing crimes, all kinds of possibilities will exist. Faced with this situation, Long Ruohai couldn't help but rub his temples.

Long Ruohai observed another observation of the credit union, an office building of the Industrial and Commercial Administration Bureau. He whispered in his mind. If an outsider commits a crime, he must check in advance. The most suitable observation location is the communication room opposite. Thinking of this, he walked towards the communication room of the Industrial and Commercial Administration Bureau.

The communication room was a retired worker on duty. A man in his sixties, except that his legs and feet were a little unstraight, was in good spirits and spoke very kindly. When he heard the police come to understand the situation, he quickly took water and cigarettes.

"Uncle, may I ask you your surname?" "Hehe, comrade. I don't have your surname Bian, and my name is Bian Changning." "Are you on duty here normally?" "Yes, yes. I work here every day."

After Long Ruohai learned that the old man was working here normally during the day, he was not polite, so he pulled a chair and started chatting with the old man. People often said that smoking and drinking were not separated. Once a few cigarettes were smoked, the relationship between the two parties suddenly heated up.

"Uncle, who often stays in the communication room during the day?" Long Ruohai was a little disappointed by the old man's answer. He said, "What do I say about this? Every day, many people pass by here, and of course there are not a few who rest here. I can't explain it clearly, young people."

When Long Ruohai saw that this was not possible, he quickly changed his questioning method and said in an inducing tone: "Uncle Bian, please help me recall it. In the past few days, have anyone who makes you feel strange has stayed here. And he has been to you more than once."

"Young man, you said this a little bit. I really can't answer you when I asked that just now. Let me think about it, let me think about it, see if there is such a person."

Uncle Bian thought for a while, then suddenly slapped his head and said happily: "Hey, I remember that there is such a strange person. This person speaks strangely. Every afternoon, he has to come to me to sit down. Well, he has been here several times. By the way, it should be three times."

After Uncle Bian's introduction, Long Ruohai was of course overjoyed. He could feel that he seemed to have grabbed a thread. Maybe this thread is the lifeline that can determine the entire case investigation.
