When Su Yan and others persuaded irrelevant people to leave, relevant personnel from the police station and criminal police team also arrived at the scene one after another.
The criminal police team was led by a deputy captain named Xu. Zhao Yang and Lu Haiping did not come this time.
Su Yan did not know the deputy captain. He had not participated in the previous cases. After Ling Yun introduced both parties, Su Yan learned that the other party's name was Xu Cheng.
As for the director of the police station, his surname is Zheng, he is about forty years old. He is from the criminal police team. Ling Yun and Xu Cheng who have worked with him respect him very much.
Both of them had obviously heard of Su Yan's name. When they heard it was him, they both looked at him curiously.
When they saw that Su Yan was so young, their eyes became even more surprised.
"Officer Su, are you interested in going to the scene with us?" Xu Cheng invited with a smile.
He had heard that Su Yan had excellent detective and reasoning abilities, and he wanted to see it if he had the chance today.
Since Su Yan had gained skills after solving the case, he naturally would not refuse their invitation. He immediately nodded and said with a smile: "Okay, I happen to be fine, so I will run errands for the two leaders."
"Haha, Officer Su is so humble." Director Zheng couldn't help laughing.
The two of them had a great impression of Su Yan for a while. Regardless of his ability to solve crimes, this young man was considered good with his humble and low-key attitude.
Su Yan left Ling Yun and others outside to cooperate with the police station on duty, and followed Xu Cheng, Director Zheng and others to the scene of the murder.
The crime scene was a toilet, because it was deep inside the factory, surrounded by deserted areas, and several hundred meters away from the nearest house.
Several security guards in the factory were on site to maintain order.
"The victim is a female worker in our factory. Her name is Zhang Yun. She is twenty-three years old." Several security guards came up and briefly reported the situation of the deceased.
"How is the protection on site?" Xu Cheng asked the security guards before entering the toilet.
"Both the deceased's family and people from the factory have gone in." A fat man who looked like a security captain replied.
"Has anyone entered the scene?!" Xu Cheng and Director Zheng both frowned upon hearing this.
When they entered the scene, Xu Cheng and Director Zheng's expressions immediately turned livid. They saw that the scene was full of new human-made traces, and clear footprints could be seen everywhere.
Seeing the chaos in the scene, the fat security captain felt ashamed. He murmured: "We once stopped them from coming in, but we couldn't stop them..."
"Why didn't you call the police immediately?" Director Zheng asked sharply.
"Our factory leader negotiated with the family of the deceased. The leader said that if the negotiation is successful, there is no need to call the police." The fat security guard replied in a low voice.
"Nonsense, this is a criminal case, you dare to know about it privately, how brave you are!" Director Zheng shouted again.
The fat security guard was so nervous that he was sweating. He said with a grimace: "Police officers, this is none of my business. It's all for the leaders and the victim's family to negotiate."
"Hmph," Director Zheng snorted coldly. He turned to the accompanying technicians and forensic doctors and nodded, signaling them to start working.
The forensic doctor who appeared on the scene today was not forensic doctor Ren, but a man in his thirties. Su Yan did not recognize him.
Although the toilet is old, it may not be used for a long time, so the smell is not bad.
The deceased was a young woman. When the clothes covering her body were removed, her lower body was naked and there were obvious pinch marks on her neck.
Following the forensic investigation, preliminary conclusions soon came out.
"The deceased, female, died due to suffocation due to strangulation of the neck. She had had sexual intercourse before her death, but there was no foreign object in her body. The time of death was approximately 10 to 12 o'clock last night. The specific time needs further investigation. Test.”
"Rape | Kill?" Xu Cheng and Director Zheng looked at each other in shock.
As for the criminal technicians, because the scene was completely destroyed, they found no valuable clues or evidence at all.
"Damn it!" Director Zheng yelled angrily again.
Of course, everyone at the scene understood how important the evidence clues from the first scene investigation were to a case. Now that the scene was completely destroyed, the investigation of the case would be very troublesome.
Su Yan frowned at the destruction of the scene.
"Does Zhang Yun have a boyfriend?" Su Yan asked the fat security guard.
The fat security guard shook his head: "No."
Su Yan looked at the forensic doctor, who understood and said: "This is not the first time that the deceased has engaged in sexual behavior."
Su Yan walked to the corpse, squatted down and observed it for a while, then said: "This murderer is very important to the deceased. The deceased valued the murderer very much."
Everyone was startled, and Xu Cheng asked: "Why do you say that?"
Su Yan pointed at the deceased's face: "Look at the deceased's makeup. It's very delicate. This shows that she dressed up deliberately before coming. In addition, her clothes are also very fashionable and decent. This proves that the deceased attaches great importance to this meeting."
When Xu Cheng and others heard this, they all nodded. Xu Cheng said, "What Officer Su said makes sense."
"In addition, the murderer should be relatively wealthy." Su Yan added.
"What do you mean?" a policeman asked curiously.
"Look at the strangulation marks on the deceased's neck..." Su Yan pointed to the strangulation marks on his neck, "There are two deep indentations, which are clearer than the surrounding marks. The murderer should have rings on his hands, and there were two of them. It was the ring that caused such a mark.”
When the forensic doctor heard this, he couldn't help but admire him and said: "I was just thinking about these two traces, but I didn't expect you to find them at a glance."
Su Yan continued: "There are two rings on one hand. The murderer may have a very high-profile style. He dated the deceased in a place like this, so he must also be from the factory."
As he spoke, he turned to the fat security guard and asked, "Have you ever noticed anyone wearing two rings in the factory on weekdays?"
The fat security guard was stunned and said, "Our deputy factory director Liu wears two gold rings on his hands on weekdays, and he was also on duty last night."
When everyone heard this, they all became excited. Deputy Factory Director Liu was very suspicious!
"I will take people to find Deputy Director Liu." Upon hearing this, Director Zheng immediately asked the security guards to lead the way and take people to find Deputy Director Liu.
In a short time, a fat middle-aged man was brought to the scene by Director Zheng.
"He is Liu Hong, the deputy director of the textile factory." Director Zheng said to Su Yan and others.
Su Yan glanced around and found that Liu Hong had a puzzled expression on his face. Apparently he didn't understand why the police were looking for him.
"Where were you from ten to twelve last night?" Su Yan asked, staring at Liu Hong.
"Oh, I left the factory at nine o'clock last night and went to play mahjong with others." Liu Hong replied hurriedly.
"When did you start playing mahjong? Have you been playing mahjong all night?" Su Yan asked again.
"The beating started at around nine o'clock and lasted all night." When Liu Hong said this, he asked nervously: "Police officers, you won't suspect me of murder, will you? Did I have time to witness last night? Can they? Prove to me that I spent the whole night playing mahjong.”
Su Yan was speechless. He looked at the rings on Liu Hong's hand and found that there were indeed two genuine ones.
