He Jiahui stood in front of the office door, looking at the big words "Special Support Group" on the door plate.

Huang Qifa, who was next to him, said with a smile: "Jiahui, this is your office, and you will be the leader of the special support team from now on! Go in and take a look. If there is anything missing, just tell me and I will have someone arrange it for you.

"

He Jiahui opened the door and walked in. He found that the room was not big, only enough for four desks. Various office supplies were prepared in the room, but there was only one set.

Seeing this scene, He Jiahui asked: "Sir Huang, how many people are there in my special support team?"

"Currently, we only have you as the team leader! But in the future, I will transfer someone here!" Huang Qifai said without blushing.

"I am the only one in the whole group! You lied to me and told me to command a group, but it turns out that I am still in charge of myself! I am the polished commander!" He Jiahui felt as if he had been on a pirate ship.

"This is only temporary. The special support team was set up in a hurry and I couldn't find a suitable candidate for a while. I will slowly search for you and I will definitely gather a whole group of people for you."

Huang Qifai continued to draw a big pie, and then said: "If you need manpower, you can go directly to Team A of the Serious Crime Unit next door. The leader of Team A is Senior Inspector Ma Jun. He is very easy to talk to! Come on, let me introduce you.

He will let you know him."

As Huang Qifai spoke, he took He Jiahui to Team A of the Crime Unit and met Ma Jun and some of Ma Jun's men.

"This is Sir Ma, who is also the leader of Group A. Sir Ma's skills are No. 1 in the police force. He has won the police free fighting championship five times in a row. The last person to win five consecutive championships was

Our first brother Chen Jiaju." Huang Qifai explained.

"He is Ma Jun, the legendary ceiling of the police force! I don't know who is more powerful, him or Abu." He Jiahui thought to himself, and then stepped forward to greet Ma Jun.

He Jiahui also heard of Ma Jun's name.

Ma Jun is recognized as the ceiling of the police force, and he is also the type who can take action and never beep.

The suspects he captured needed to be sent to the hospital for rescue first, and then sent to the interrogation room for interrogation. There were also suspects who did not open their eyes, thinking that they were good at resisting the Ma Jun, but they were directly beaten into fools by the Ma Jun.

Huang Qifai pointed at an older police officer, and then introduced: "This is Uncle Hua. Uncle Hua has been in the world for a long time. If you want to check old accounts, he is the right person to turn to."

"This is Yang Zai!" Huang Qifai pointed at a tall and strong young man and introduced: "Yang Zai's father was a dragon and tiger martial artist back then. Yang Zai also learned kung fu since he was a child, and his skills are also very good!"

"This is Cannon. Do you know why we call him Cannon? Because his marksmanship is very accurate! He used to be a sniper of the Flying Tigers!"

"The one who looks like a bad guy is A-Chen. Even though he looks like a gangster, in fact he has really been a gangster. A-Chen worked as an undercover agent for three years before and has a lot of connections."

Ma Jun's team is indeed full of talents.

After the introduction, Huang Qifai continued: "Now we all know each other. Jiahui, Ajun, and the Chinese University case will be handed over to you. This case is being pressed very hard from above, and I hope you can work together to solve it.

Solve the case soon!"

After Huang Qifa left, Ma Jun said in a strange tone: "Sir, the commander asked me to cooperate with you on this case. What should we do next? We are still waiting for Sir He's instructions!"

He Jiahui knew that Ma Jun was unhappy because he robbed his case.

Faced with the ceiling of the police force's strength, Ho Ka Fai did not respond tit for tat. After all, he was just a polished commander, and he still expected Ma Jun's men to handle the case.

So He Jiahui said, "I'm new here, and I still have a lot of things to ask Sir Ma for advice. Well, tonight I'll be the host and invite the brothers from the crime team to have a light meal together. I wonder if Sir Ma is willing to show his respect? "

He Jiahui knew that as long as Ma Jun agreed to a treat, his men would definitely not refuse.

However, Ma Jun shook his head: "There have been a lot of cases recently. The serial murder case at Chinese University has no clues at all. How can our crime team have time to go out for dinner!"

"Sir Ma, only after you have eaten enough can you have the strength to solve the case! I know a restaurant that does a pretty good job of stewed abalone wings with fire-pupil chicken. Brothers, after working on the case for so long, it's time to replenish your health." He Jiahui Then he said.

"You just eat shark's fin for casual meals? Sir He is really rich." Ma Jun said sarcastically.

He Jiahui smiled slightly: "I'm not married, I'm single, I don't even have a girlfriend, and I have nowhere to spend the money I make, so why not treat my brothers to a nice meal? Don't let the wealth go to outsiders."

When they heard that abalone and shark fin were available, several police officers from the crime team all showed their eyes. Regardless of their stance, who wouldn’t want to eat something good these days?

"Well, since Sir He kindly invites us, if we don't go, wouldn't it be disrespectful to Sir He!" Ma Jun nodded.

Ma Jun is also a good person. He can see that his subordinates really want to enjoy this feast of fire-eyed chicken and stewed abalone wings. If they stop him at this time, it will harm everyone's interests.

Rather than making everyone unhappy, it is better to be a favor and go to dinner together. Anyway, Ho Ka Fai is paying for it.

"Fire-eyed chicken and stewed abalone wings are quite expensive. If you dare to rob my case, you, a big dog, will be defeated by then!" Ma Jun thought to himself, and at the same time gave his subordinates a look.

The subordinates all responded with their eyes, saying that they would eat with open stomachs and order more dishes to max out He Jiahui's credit card!

…

In the special support team, there is only Ho Ka-fai, the polished commander. He alone occupies a fairly small office, and the sergeant enjoys the treatment of a chief inspector.

The case file of the serial murder case was also sent to He Jiahui.

After reading the dossier, He Jiahui felt a sense of powerlessness in his heart.

The content recorded in the file is similar to what Huang Qifai dictated. The interpersonal relationship between the two deceased persons was relatively simple. They had no enemies, no debts, no emotional disputes, and no known members of the community. Their daily lives were limited to home and school.

At the crime scene of the two deceased persons, one was burned by fire and the other experienced a typhoon. All traces have been erased and no clues have been found that could help solve the case.

"No wonder the case has been in Ma Jun's hands for so long, but he has not made any progress. With the information in his hands, it is difficult to determine the direction of the investigation!" He Jiahui thought to himself.

The most important thing in solving this kind of case without clear clues is to choose a correct direction of investigation, and this is also the most difficult part in the process of solving the case.

Theoretically, as long as everyone and everything related to the deceased are investigated, clues will definitely be found.

However, in the actual investigation process, the police cannot invest so much manpower to find out the details of every incident.

Therefore, the police often start investigating key items, such as interpersonal relationships, emotional relationships, debt relationships, etc. These aspects are most likely to lead to the occurrence of the case.

If no clues can be found in these aspects, then a new direction of investigation must be determined, which is also the most difficult part.

If you choose the wrong direction in this new direction, it means that the time and energy spent will be in vain, and everything will have to start from scratch.

With limited police resources, every wrong choice of investigation direction can be fatal.

The police also have other cases to investigate, and it is impossible to focus their police force on this one case all the time, and they do not have so much time and energy to slowly make trial and error.

If the same case is investigated in the wrong direction several times, the resources invested in it will gradually decrease. As resources gradually disappear, the case will no longer be investigated, and it will become an unsolved case.

Therefore, solving crimes requires timeliness. The closer the crime occurs, the easier it is for the suspect to be caught. The longer it takes, the more difficult the investigation will be, and the lower the possibility of catching the suspect.

Not only because the case drags on for a long time, there will be fewer clues and the suspect will have more time to escape, but also because the case is delayed for too long and sufficient police resources cannot be guaranteed to continue the investigation.

Take a murder case as an example. The diamond time to solve a case is 48 hours. During this time period, more clues will be left at the scene. Even the murderer has not left the scene, so it is naturally the easiest to solve the case.

Within one week after a crime occurs, it is the prime time to solve the case. During this period, forensic doctors and forensic evidence can provide the greatest help. The deceased's interpersonal relationships, debt issues, etc. can also be found out. Ninety percent of murder cases occur within a week.

Broken.

Three months is considered a golden period of time for solving a case. During this period, all the investigative methods and technological methods that should be used have been used, and all the clues that can be found have been found. If the case cannot be solved, then the case will basically be solved.

Hanging.

Within one year after the incident, it is the bronze time to solve the case. By this time, all the means of solving the case must have been used. Basically, we are in the stage of waiting for the arrival of the goddess of luck.

If you're lucky, a clue will suddenly come to you and the case will be solved. If you're not lucky, if there are no new clues, you'll just have to wait for the end of the year assessment to fail!

The current case has been a month since the first victim was murdered, and more than a week since the second victim was murdered, which is the golden time period for solving the case.

At this stage, if you work harder, the case may be solved; but if there is no progress after a month or two, the case will become unsolved.

He Jiahui has rich experience in solving crimes, and at this time he has already thought of a new direction of investigation.

…

In the restaurant, police officers from the regional serious crime team A gathered around the table, each holding a bowl of fire-pupil chicken stewed with abalone wings.

"It's so nourishing. I'm sweating all the time I eat!" Uncle Hua picked up a tissue and wiped the sweat from his head.

"Uncle Hua, the air conditioner has been turned on very low, why are you still sweating profusely after eating!" Yang Zai next to him said.

Uncle Hua looked at Yang Zai, who had a normal expression, and said with a smile: "Yang Zai, you can't even blush after eating such a bowl of supplements. You must be suffering from kidney deficiency!"

"Nonsense, I'm so good at fighting, how can I have kidney deficiency!" Yang Zai said.

Next to him, Achen laughed and joked: "Yang Zai is suffering from kidney deficiency. He is young and needs to grow up!"

I have to say that the dinner party culture is really a good thing. After eating a luxurious meal, He Jiahui became more familiar with everyone, and the members of the crime team no longer mentioned He Jiahui's robbery case.

After all, eating people's hands are short, and taking people's mouth is short. After eating Ho Jiahui's Fire Eye Chicken Stewed Abalone Wings, no one would be embarrassed to say anything about him.

Ma Jun said: "Sir He, now this serial murder case is handed over to you. Have you read the files all afternoon and determined a new direction of investigation?"

He Jiahui knew that it was time to show off his abilities at this time to convince Ma Jun, so he put down his chopsticks and said;

"The relationship between the two deceased persons was simple. There were no enemies, no debt disputes, and the crime scene had been destroyed. It is difficult for us to find new clues from the deceased's side alone. Since there are no clues from the deceased's side, So I plan to launch an investigation from the murderer’s side.”

"We don't have any information about the murderer. We don't know whether he is tall or short, male or female, or how old he is. How can we investigate the murderer?" Ma Jun asked immediately.

"We can start the investigation from the murderer's motive. There are only a few motives for killing, including money, love, revenge, and murder to silence."

He Jiahui paused and then said: "The two deceased are ordinary college students. Their families are not rich, so it cannot be a murder. The relationship between the two and their girlfriends is also very stable, so love murder can be ruled out. As for vendetta, it is not possible yet. Rule out this possibility."

"We have checked that the two deceased people had no enemies and had no conflicts with anyone. We can rule out vendetta," Ma Jun said.

He Jiahui shook his head: "If we only consider personal grievances, we can indeed rule out the possibility of vendetta, but what if the student union did something and offended the enemy?

The enemy was angry at the student union, so he planned to take revenge. One of the two deceased was the president of the student union, and the other was the vice president, so they will inevitably become the primary targets of the murderer's revenge!"

"The student union is just a student organization. What kind of enemies can we offend that require killing people to get revenge?" Ma Jun said.

"We need to investigate this." He Jiahui paused, and then said: "The current university student union is actually quite crazy. It makes things happen every day. At best, it is independent, and at worst, it is independent. Causing trouble everywhere.

These college students don’t have any brains. Once they are incited by people with good intentions, they will only be brave. These students don’t know the dangers of society. Maybe they don’t even know when they have offended someone!”
