Teaching Building Female Corpse Case (3)

The man standing in the inquiry room was wearing a grey shirt with a black jacket on top, which was open. Because the jacket was too small, the sleeves of the shirt were exposed. Meng Siqi recognized the shirt at a glance, as it belonged to the uniform of a security guard.

Meng Siqi slowly came back to his senses from the button on his cuff. The button reflected a low-gloss light when it was shaking, and it was very similar to the button in the picture.

Is he the murderer? Meng Siqi was not completely sure. She gradually calmed down. After all, there should be more than one security guard wearing a uniform like this. Moreover, the details of the buttons in her memory were vague. She had to investigate further.

After asking for basic information, Tang Xiaochuan got straight to the point and asked, "Mu Zhiquan, were you on duty at the school last night?"

"Yes, I was on duty yesterday, and I was relieved early this morning." The security guard named Mu Zhiquan is about 30 years old, with short hair, neither fat nor thin. He looks energetic, but the area around his eyes is dark, which may be related to staying up late frequently.

The person who reported the case was another security guard who was on shift this morning. Han Changlin questioned his testimony in the morning but did not obtain any useful clues.

When Tang Xiaochuan asked, "Where were you around ten o'clock last night?", Han Changlin unconsciously became very alert. In the absence of any clues, Mu Zhiquan might be the only breakthrough in this case.

At noon, Han Changlin didn't even eat a bite of food. He was suddenly called to the office by the director. Director Liu told him that the murder of a high school teacher would have a great social impact and they must hurry to solve the case.

The director asked him to give a time limit for solving the case.

At that time, Han Changlin was not sure how long it would take to solve the case, because there was no clue at all. But he wanted to achieve results this year, so he was a little nervous and slowly stretched out five fingers.

Director Liu said in a firm voice: "Han Changlin, I am waiting for your good news. I don't want this case to have no progress for ten days or half a month!"

Director Liu said decisively: "If the case is not solved in five days, then the case will be handed over to Team One!"

Chief Han Lin issued a military warrant a few months ago. This case is undoubtedly a test for him. Over the years, the presence of Team 2 has been almost zero. There was a discussion in the bureau about merging Team 2 into Team 1, so Chief Han Lin issued a military warrant.

Coming out of the director's office, he met two colleagues from the team. They were talking about a case they had just solved. They solved the case in three days and were praised by the bureau.

The two colleagues saw Han Changlin and said jokingly, "Captain Han, your case is not a simple one. If you need help, just let us know and we will definitely ask the road team to help."

Han Changlin curled his lips, forced a smile, and shook his neck unnaturally.

"It rained last night, so I didn't patrol the whole school. I just walked around the playground." Mu Zhiquan was answering Tang Xiaochuan's question.

Han Changlin also quickly came back to his senses and his eyes once again focused on Mu Zhiquan's facial expression.

Beads of sweat appeared on his forehead, which were particularly dazzling under the dim light. I don't know if it was because of nervousness or just a normal physiological reaction in this closed interrogation room.

The entire questioning process went according to plan. Meng Siqi took notes while observing Mu Zhiquan's expression. She found that Mu Zhiquan spoke very quickly and every sentence was affirmative. For example, he said that he went out for patrol at around 10:10 yesterday.

She tried to find loopholes in the words, but every sentence seemed to prove his alibi.

Last night, Zhou Jie Li was the only teacher left at school, and Mu Zhiquan was the only security guard on duty. He could not be ruled out as a suspicion, unless there was a third person there last night.

It was not until Mu Zhiquan said something that the pen in Meng Siqi's hand suddenly stopped.

She could sense that the Korean team and Tang Xiaochuan also straightened up without making a sound.

Mu Zhiquan said: "Last night, around 10:30 to 10:40, I was walking on the playground and saw a figure."

"Human figure?" Han Changlin asked in a voice that sounded doubtful and slightly surprised.

Tang Xiaochuan immediately asked: "Did you see who it was?"

"I remember there was a flash of lightning and I definitely saw his appearance, but at that moment, I was not sure."

"Think about it carefully." Tang Xiaochuan asked again.

"I feel like that person is Teacher Zhou's husband."

Almost at the same time, Tang Xiaochuan and Han Changlin exchanged glances. The next second, Tang Xiaochuan said in a serious tone, "Mu Zhiquan, please think about it carefully. Are you sure the person you saw was Zhou Jieli's husband Zhao Guanghui? You must understand that this is a very important clue."

Mu Zhiquan seemed to think about it before answering: "I... am sure."

"Recall again where Zhao Guanghui was last night, what he was wearing, and what you saw."

Mu Zhiquan put his hands on the table, staring at his intertwined fingers without looking up, as if he was racking his brains to recall the scene.

After a while, he slowly spoke: "He should have been at the entrance of the teachers' building, wearing white clothes, but I couldn't see clearly what he looked like. But when I checked, he was gone. I guessed that it was Teacher Zhou's husband who came to see her that night, so I didn't think much about it. The lights in Teacher Zhou's room were off at that time, so I guessed she had already fallen asleep."

Meng Siqi remembered that Zhao Guanghui was wearing a white sweater today, and his spare jacket was also white. He should prefer wearing white, but this cannot prove that the murderer is Zhao Guanghui. It only means that he has this habit.

"How long have you known Zhao Guanghui? How much do you know about him? Can you describe what you know about his relationship with Zhou Jie Li?" Tang Xiaochuan continued to ask.

Mu Zhiquan paused for a few seconds, bit his lip, as if he was organizing his words, and then said: "Teacher Zhou is an excellent teacher in the school. He is very kind to his colleagues and students, and also to us security guards. Sometimes he will take the initiative to say hello when he sees us."

As he said this, his eyebrows raised noticeably.

"So I naturally got to know Zhao Guanghui. He often came to school. Maybe others didn't know it, but I definitely knew it."

"How should I put it?" Mu Zhiquan's expression slowly sank, his brows slightly furrowed, "It was like he was monitoring her."

The word "surveillance" stirred up everyone's emotions again, but no one interrupted Mu Zhiquan's testimony at this time.

"In the first half of this year, I don't remember the exact time, the two had a quarrel at school. At that time, Zhao Guanghui violently dragged Teacher Zhou from the classroom to the car. He kept shouting, "Explain it!"

Meng Siqi took notes seriously. She also knew that the Korean team must know about this, so everyone was listening and no one interrupted.

Mu Zhiquan continued, "Zhao Guanghui must have thought that Teacher Zhou had someone else outside."

This sentence instantly brought everyone's emotions to a boil. It was undoubtedly a key clue in this case.

The tip of Meng Siqi's pen seemed to be solidified on the paper, and the ink from the pen was embedded in the paper. She didn't know how to write down these words. Was this slander, delusion, or truth?

"Did you see it with your own eyes?" Principal Han Lin asked sternly. In the morning, he had consulted the school about the situation, and apart from the quarrel, he had not found any information that Zhou Jie Li had cheated on her.

"Of course not. Teacher Zhou is very popular in school and doesn't have close contacts with others. She wouldn't do such a thing." Mu Zhiquan shook his head in denial.

"Then why do you think Zhao Guanghui would have such an idea?" Han Changlin asked.

"Zhao Guanghui was monitoring her. Sometimes he would not even enter the house, but would go to the school to check. He must have been worried that Teacher Zhou was out alone and had an improper relationship with someone else. What did Zhao Guanghui want her to explain during that quarrel? It was such a big fuss, except for the matter between men and women."

"But these are just your guesses." Han Changlin interrupted him at the right time.

The one-hour conversation finally ended. Han Changlin walked out with brisk steps. Meng Siqi could clearly feel that Han Changlin was excited.

Needless to say, the interrogation just now played a decisive role. According to Mu Zhiquan's description, if Zhao Guanghui really appeared in the school last night, then a new suspect has emerged.

Everyone gathered in front of the crime board in the office, which was covered with clues closely related to Zhou Jie Li.

Tang Xiaochuan made a brief analysis of the case. What can be confirmed at present is that there were only Zhou Jie Li and security guard Mu Zhiquan in the school last night, and Mu Zhiquan is the most suspicious.

But Mu Zhiquan discovered another suspect, Zhou Jieli's husband Zhao Guanghui.

According to the autopsy report we just received, the deceased had red spots on her lung pleura, commonly known as Tadiao's spots, which are consistent with the characteristics of mechanical asphyxiation. Zhou Jie Li was strangled to death by someone who strangled her throat.

There were empty bottles of alcohol in Zhou Jie Li's room. The murderer must have used alcohol to wipe off the fingerprints on the victim's neck afterwards.

Tang Xiaochuan added: "There is still one investigation that has not been concluded. The stomach contents of the deceased have been sent for examination, but it will take some time."

He continued to explain the on-site trace inspection.

Nothing was lost at the scene. The 400 yuan in cash in the drawer was intact, and Zhou Jie Li still had the gold ring on her finger.

There were no signs of a struggle at the scene, and there were no signs of doors and windows being pried open or damaged. The murderer deliberately cleaned up the footprints on the ground after leaving.

Judging from all these clues, the murderer must be someone Zhou Jie Li knew, and the two of them had a close relationship, so it was definitely not a murder for money.

Tang Xiaochuan said: "There is a key clue. The deceased was sexually assaulted before his death. His lower body was slightly torn, but no semen was detected."

"If it was rape and murder, it makes sense, but why was no semen detected?" Han Changlin asked puzzledly.

There was silence in the air for a while, and Feng Shaomin said slowly: "There may be several reasons. For example, the murderer has sexual dysfunction, which leads to blockage of the vas deferens; or the murderer stopped halfway for some reason; there is another situation..." He paused, and then said, "The murderer may just want to mislead others."

"Misleading?"

"The murderer did not intend to rape, but I hope the police will investigate in this direction."

After Feng Shaomin finished speaking, the office fell silent. Everyone had heavy expressions and tearful eyes as they thought about these words.

For the first time, Meng Siqi felt the tension of solving a case. Her chest felt tight, but she didn't have any special thoughts as she had just learned many of the clues.

Han Changlin continued to ask: "Did you find anything under the fingernails of the deceased?"

Tang Xiaochuan reviewed the autopsy report again, shook his head, and added: "The inside of the nails is very clean."

"This is very strange." Han Changlin wondered, "The scene was too quiet. Whether it was rape or choking, the victim would fight back desperately. During this process, she would grab something, such as the murderer's skin tissue or clothing fibers. It's not surprising that the murderer cleaned the scene. Could he have deliberately cleaned his nails?"

If this is the case, then the murderer is too perverted. Everyone's expression became serious.

Feng Shaomin said calmly: "If the murderer was someone the deceased knew very well, he might have used a lot of force to sneak attack and caused the victim to faint quickly, making him unable to fight back."

Han Changlin caught Zhao Leiting's eager look and said, "Hurry up."

Zhao Leiting said: "When a person is strangled, only two kilograms of pressure is enough to cause cervical venous obstruction. If the pressure is much greater than two kilograms, the deceased may indeed suffer from insufficient blood supply to the brain for a short period of time, lack of oxygen and coma."

Zhao Lei Ting stopped talking and looked at everyone again, as if waiting for their approval, but no one responded. When he looked at Meng Siqi, Meng Siqi understood and gave him a faint smile.

After Han Changlin simply said "hmm", Zhao Leiting's raised eyebrows drooped slightly.

Han Changlin stared at the crime board in deep thought. After a while, he slowly loosened his fingers that were pinching his lower lip, his eyes slightly brightened, "In terms of height, Zhao Guanghui has an advantage over Mu Zhiquan, but compared to the naturally weak victims, they are both likely to make the victims faint for a short time; however, in terms of the degree of relationship, Zhao Guanghui's identity is more likely to reduce the victim's defense. Moreover, he has a motive for murder--"

"Zhou Jie Li and Zhao Guang Hui have been separated for more than half a year, and their relationship had problems a long time ago, especially the time when Zhao Guang Hui abused Zhou Jie Li at school. The relationship between the couple became estranged, and perhaps Zhou Jie Li filed for a divorce, which made Zhao Guang Hui turn his love into hatred, and he killed her last night. After killing Zhou Jie Li, he created the illusion of 'rape' to direct the suspicion to others..."

It seems to be very close to the truth. Feng Shaomin said: "If Mu Zhiquan did not lie, then Zhao Guanghui is the first suspect. Moreover, he lacks an alibi. He said that he was running an empty car outside at that time last night, with no passengers. This is unbelievable."

Han Changlin said in a loud voice: "Tang Xiaochuan, apply for an arrest warrant and ask Zhao Guanghui to come back for questioning."

Ten minutes later, when Meng Siqi was about to step into the departing police car, Feng Shaomin's cold voice came from the back seat: "Why are you arresting a girl? The Korean team should just let her go back!"

Han Changlin turned his head and said to the window, "Xiao Meng, sort out the clues from today's evidence collection."

"...Okay, Korean team."

Watching the car speeding away, Meng Siqi felt a little lost.

On her way back to the office, she always felt uneasy, as she always felt that Mu Zhiquan was lying.

But who can prove that he lied? Where can the evidence come from?

Meng Siqi hesitated for a moment, but decided to go and collect evidence in person.
