After listening to He Jiahui's reasoning, the forensic officer looked at Huang Qifai. Huang Qifai was the officer in charge of this case, and he was also the chief inspector. It was still up to Huang Qifai to make decisions on the investigation of the case.

Huang Qifai's face was gloomy, and his rationality told him that he could give it a try according to He Jiahui's reasoning. If it was really what He Jiahui said, the case would be solved immediately.

However, as the chief inspector of the serious crime team, Wu Qiqi was really worried about his face being taught how to solve cases by a school police officer. So he did not speak for a long time, torn between solving the case and saving face.

He Jiahui had already seen through Huang Qiqi's thoughts. He lowered his voice and said: "Inspector Huang, you are the sir in charge of this case. If the case is solved, it is not you who has the final say on how to write the report!"

He Jiahui's words awakened the dreamer, and Huang Qifa instantly realized that even if a police officer solved the case, he would just give himself more credit when writing the case report.

Thinking of this, Huang Qifai planned to accept He Jiahui's suggestion. He turned to look at the forensics. Just as he was about to ask the forensics to examine everyone's sportswear, someone in the crowd said:

"He Jiahui, the murder weapon obviously appeared in your cabinet. You are the biggest suspect. Why are we involved in the investigation? This is unfair to us."

He Jiahui turned around and saw that it was squad leader Qiu Junxuan who was shouting.

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

If a 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 his daily performance. If he has a bad record, he will almost never win the award.

In the same way, after a trainee police officer becomes a police officer, past performance will be considered for every promotion. It will not look good if you carry a record of being investigated by the crime squad.

Squad leader Qiu Junxuan's usual performance is very good. He often takes first place in assessments. He must be rushing for the Silver Flute Award or Xue Fu Cup. It is normal not to want his personal record to be stained.

Zhou Liang, the head of the room next to him, also said: "According to what He Jiahui said, then every one of us here may be the murderer. Do we need to investigate every one of us? Then everyone's records will be affected!"

As soon as these words were spoken, other school police officers expressed their agreement. After all, this was related to personal interests.

Even the instructor helped: "Inspector Huang, I feel that if all student police officers are to be investigated, it will indeed cause panic. Such a large-scale investigation will not only affect personal records, but also affect our future." training.”

The trainee police officer was worried that his personal record would be affected, the instructor was worried that it would be difficult to lead the team in the future, and Huang Qifa was a little soft-spoken and hesitated again.

"Looks like I have to take action!" He Jiahui sighed softly, and then said: "I don't want to cause trouble to Sir and all my classmates. Let me sort out the case from the beginning and narrow down the scope of the investigation.

The time of death of the deceased was between 8:30 and 10:00. The scene of the first crime was the kitchen, so the murderer met the deceased in the kitchen after 8:30. Since the murderer had no preparation for killing before, he used it conveniently. The kitchen knife was used as the murder weapon to kill the deceased.

The murderer then needs to move the body of the deceased and hide it in the freezer, and clean up the blood stains at the scene and on the murder weapon. During this process, the murderer's clothes will inevitably be stained with the blood of the deceased.

This is a police academy, and there are people everywhere. If the murderer wears blood-stained clothes and moves around in the police academy, he will be too conspicuous and will be seen by others, and then his murder will be exposed.

Therefore, the murderer needs to do one more thing, which is to clean the blood stains on his clothes when cleaning up the scene, and then return to the dormitory, so that no one will notice.

Cleaning up the blood stains will definitely make the clothes wet, which will narrow the scope a lot. You can recall that during the gathering time from 8:30 to 9:30 this morning, whose clothes are wet may be the murderer.

"

"Wait a minute! There is a loophole in your statement!" Huang Qifai suddenly interrupted He Jiahui, and then said: "The murderer deliberately killed someone on a temporary basis, and it was impossible to prepare a change of clothes in advance.

According to your statement, although the murderer cleaned up the blood stains, his clothes were also wet, which means that he would wear wet clothes to show off in the police academy. It's a sunny day today, wouldn't it be wrong if he wore wet clothes?

Will it arouse others' suspicion?"

"Inspector Huang, if you are wearing a suit and tie and the clothes are wet, it will indeed make people suspicious, but if you are wearing sportswear, sweating profusely, and just came back from outside. You see the front of the sportswear

My back is wet, do you think it’s water or sweat?”

He Jiahui continued: "This is a police academy, and there is no shortage of hard-working police recruits. After completing daily training, many students will take time to do additional training to improve their performance.

The murderer only needs to say that he has just practiced more physical fitness, and people who see him will think that the wet clothes on his clothes are sweat! So the question is, after breakfast today, which classmate did not return to the dormitory immediately, but went to

Are you doing more physical training?"

He Jiahui said, scanning the crowd with sharp eyes like an eagle.

He then continued: "Actually, the scope of the investigation can be further narrowed. The murderer put the murder weapon in my cabinet and took away a piece of my sportswear. It was impossible to do it when there were many people, as that would be easily discovered by others.

So he must find a time when there are few or no people to do this. We can check who were the last people to leave the dormitory when we gathered at 9:30, and who were the first to come back after the morning training.

Who is the individual.

Those who left last and those who came back first had time to commit crimes, plus those who went out to practice more physical fitness after breakfast, I think there are not many people who meet the above conditions, right?"

"I remember Qiu Junxuan went to do some physical training 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!" Another person said.

"After breakfast, Ah Wei also went to practice some more, right? And he came back very early at noon." Someone else said.

Someone immediately responded: "During the extra training in the morning, Ah Wei and Ah Zhong were together. The three of us can prove to each other that we have never been to the restaurant."

"By the way, I met Zhou Liang when I went downstairs. His clothes were wet. I also said why he practiced so hard and his clothes were soaked through!" someone else said.

Squad leader Qiu Junxuan also remembered something: "Having said that, I remembered it. I was responsible for counting the number of people before training. When we gathered at 9:30, Zhou Liang was the last one to arrive!"

The next second, everyone's eyes turned to Zhou Liang, the head of the house.

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

"Stop him!" Huang Qifai shouted.

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

"Where is his wardrobe?" Huang Qifai asked next.

"That's it!" The instructor quickly pointed to Zhou Liang's wardrobe.

Huang Qifai looked at the forensic evidence, who nodded, carried the toolbox to the closet, found Zhou Liang's sportswear inside, and sprayed it with luminol.

"There is a blood reaction!" Forensic said.
Chapter completed!
