After listening to He Jiahui's reasoning, the forensic evidence looked at Huang Qiqi, Huang Qiqi is the chief in charge of this case, and he is also the chief inspector, and the problem of case investigation still depends on Huang Qiqi's decision.

Huang Qiqi had a gloomy face, and reason told him that he could give it a try according to He Jiahui's reasoning, in case it was really what He Jiahui said, he could solve the case immediately.

However, as the chief inspector of the serious crime team, he was taught how to solve the case by a student policeman, and Wu Qiqi's face was indeed a little unbearable. So he didn't speak for a long time, torn between solving the case and saving face.

He Jiahui had already seen through Hehuang's thoughts, he lowered his voice and said: "Inspector Huang, you are the sir in charge of this case, if the case is solved, how to write the report, it's not up to you to decide!" ”

He Jiahui woke up the dreamer with a word, and Huang Qiqi instantly realized that even if he was taught by a student police officer to solve the case, when he wrote the closing report, he would just add more credit to himself.

Thinking of this, Huang Qiqi was about to accept He Jiahui's suggestion, he turned his head to look at the forensic evidence, and was just about to open his mouth to let the forensic test everyone's sportswear, but someone in the crowd said:

"He Jiahui, the murder weapon obviously appeared in your cabinet, you are the biggest suspect, why should we be investigated together? It's not fair to us. ”

He Jiahui turned his head to look, and it was the squad leader Qiu Junxuan who shouted.

"Are you worried that being investigated will leave you with a bad record and affect your winning the Silver Flute Award? Or will it affect your promotion after becoming a police officer? He Jiahui asked calmly.

If the cadet police officer wants to win the Silver Flute Award and the Xue Fu Cup when he graduates, he must not only look at the results of each assessment, but also look at the daily performance, and if he has a bad record, he will almost miss the award.

In the same way, after the cadet police officer becomes a police officer, every promotion will refer to his past performance, and if he carries a record of being investigated by the serious crime team, it is always not good-looking.

The squad leader Qiu Junxuan's performance is usually very good, and he often wins the first place in the assessment, he must be running for the Silver Flute Award or the Xue Fu Cup, and it is normal not to want his personal record to be stained.

Zhou Liang, the head of the room next to him, also spoke: "According to He Jiahui's teaching, then every one of us here may be a murderer, do you want to check each of us?" Everyone's records will be affected by that time! ”

As soon as these words came out, other cadet police officers echoed them, after all, this is a matter of personal interests.

Even the instructor helped: "Inspector Huang, I think if you want to investigate all the student police, it will indeed make people panic." This kind of large-scale investigation will not only affect our personal records, but also affect our future training. ”

The cadet police officer was worried that his personal records would be affected, and the instructor was worried that the team would not be easy to lead in the future, and Huang Qiqi was a little soft-eared, and suddenly hesitated again.

"Looks like I'm going to have to do it!" He Jiahui sighed lightly, and then said: "I don't want to cause trouble to Sir and my classmates, so let's sort out the case from the beginning, and the scope of the investigation should be narrowed."

The time of the deceased's death was between 8:30 and 10:00, and the first crime scene was in the kitchen, so the murderer met the deceased in the kitchen after half past eight. Since the murderer was not prepared to kill before, he casually used a kitchen knife in the kitchen as a murder weapon to kill the deceased.

Then the murderer needs to carry the body of the deceased and hide it in the freezer, clean up the blood stains on the scene and the murder weapon, and in the process, the murderer's clothes will inevitably be stained with the blood of the deceased.

This is the police academy, there are people everywhere, if the murderer wears a bloodstained dress in the police academy, it is too conspicuous and will be seen by others, and then his murder will be exposed.

So the murderer still needs to do one thing, that is, when cleaning up the scene, clean up the blood stains on his clothes, and then return to the dormitory, so that he will not be noticed.

Cleaning up the blood stains will definitely get the clothes wet, so the scope will be much narrower, you can recall, this morning from half past eight to half past nine this time period, whoever is wet clothes, who may be the murderer. ”

"Wait a minute! There's a loophole in your claim! Huang Qiqi suddenly interrupted He Jiahui, and then said: "The murderer is a temporary murderer, and it is impossible to prepare a change of clothes in advance.

According to you, although the murderer cleaned up the bloodstains, his clothes were also wet, which means that he had to wear a wet suit to swagger through the police academy. It's a sunny day, and wearing a wet suit won't arouse suspicion? ”

"Inspector Huang, if you wear a suit and tie like you, but your clothes are wet, it will indeed make people suspicious, but if you are wearing sportswear, sweating profusely, and have just come back from outside. When you see that the front and back of your tracksuit are wet, do you think it's water, or sweat? ”

Ho Ka-fai continued: "This is a police academy, there is never a shortage of hard-working recruit police officers, and many students will take time to practice after completing their daily training to improve their grades.

The murderer only needs to say that he has just trained his physical fitness, and those who see him will think that his clothes are wet with sweat! So the question is, after breakfast today, which student did not return to the dormitory immediately, but went to practice physical fitness? ”

He Jiahui said, sweeping towards everyone with a sharp gaze like an eagle.

Then he continued: "In fact, the scope of the investigation can be further narrowed. The killer put the murder weapon in my cabinet and took away one of my tracksuits, which is impossible to carry out when there are many people, so that it can be easily discovered.

So he had to find a way to do it when there were few people or no one. We can check who were the last people to leave the dormitory when they gathered at half past nine, and who were the first people to come back after the morning training.

The last to leave and the first to come back have time to commit crimes, plus people who go out after breakfast to practice physical fitness, I think there should be few people who meet the above conditions, right? ”

"I remember Qiu Junxuan went to practice his physical fitness after breakfast!" Someone looked at the squad leader.

"Junxuan was the first to go down to gather, he didn't have time to put the murder weapon!" The other spoke.

"After breakfast, Ah Wei also went to practice, right? And I came back early at noon. Someone else spoke.

Someone immediately responded: "When I practiced in the morning, I was with Ah Wei and Ah Zhong, and the three of us can prove to each other that we have not been to the restaurant." ”

"By the way, when I went downstairs, I met Zhou Liang, his clothes were wet, and I also said how he practiced so hard, his clothes were soaked!" Someone else spoke.

The squad leader Qiu Junxuan also remembered something: "I remembered that I was responsible for counting the number of people before training, and when I gathered at half past nine, Zhou Liang was the last to arrive!" ”

In the next second, everyone's eyes were all on the head of the house, Zhou Liang.

But Zhou Liang suddenly turned around and rushed towards the door, intending to escape.

"Stop him!" Huang Qi shouted.

There were Huang Qiqi's subordinates at the door, and when they heard his shout, they immediately blocked the door and easily subdued Zhou Liang.

"Where's his closet?" Huang Qiqi then asked.

"It's this!" The instructor hurriedly pointed to Zhou Liang's wardrobe.

Huang Qiqi looked at Forensics, Forensic nodded, walked to the wardrobe with the toolbox, found Zhou Liang's sportswear inside, and sprayed it with luminous ammonia.

"There is a bloodstain reaction!" The forensic officer spoke.

He Jiahui suddenly breathed a sigh of relief: "The murderer has been found, and the truth has been revealed!" ”
