Take the old attack to solve the case

"Through the identification of...the wound, it can be confirmed that the murderer cut the...flesh of the deceased from the body and chopped it with a knife on the chopping board. Since no murder weapon was found at the scene, I can only speculate temporarily. , the murder weapon was a kitchen knife, or a knife of this type that is easier to cut..."

Zhan Xinyi made a simple sentence a little intermittent. The murderer was too cruel, cutting human flesh into pieces like animal meat. Zhan Xinyi spent a whole day unable to fully identify the specific details of those pieces of meat on the body. Location.

In order to preserve these dismembered corpses, Zhan Xinyi had to pack them in several large plastic boxes and put them in the morgue.

Faced with this kind of dismembered corpse case, it was the most powerless moment for the forensic doctor. Zhan Xinyi almost stayed up all night last night, trying to find clues from these dismembered corpses, but until now, dozens of hair samples have been found. , but Zhan Xinyi suspected that there was probably no murderer.

"The samples are still being analyzed, but I have reason to suspect that the murderer committed the crime wearing a waterproof jumpsuit." Zhan Xinyi said.

"I agree with Zhan Xinyi's idea." Pan Qingyue raised the pen in his hand and said: "The footprints we found in the plasma at the scene before, at first we suspected that they were wearing shoe covers, but the bloody palm prints on the wall, and Several marks were made of extremely smooth material stained with blood and smeared on the wall, most likely a waterproof jumpsuit."

Pan Qingyue's identification of various traces can be regarded as very accurate. The master who took him back then was an old policeman who had done on-site investigation for more than 30 years.

Zhang Zimu believed in Pan Qingyue's judgment. If the murderer was wearing a waterproof jumpsuit, it meant that it was a planned murder, and it also meant that the murderer would try to avoid leaving clues at the scene.

"Any new discoveries at the scene?" Zhang Zimu asked.

Today, Pan Qingyue led the team to investigate the crime scene for the second time. He shook his head and said, "There are no new discoveries yet, and the items brought back are still being analyzed."

Sun Liang raised his hand suddenly at this time, seeing Zhang Zimu nodded to him, stood up and said: "I can't figure out one thing, judging from the blood splattered at the scene, Li Lihong was killed standing in the living room, if the murderer was wearing The one-piece suit committed the crime, why did Li Lihong let a person in a waterproof one-piece suit enter the door?"

Everyone was stunned.

Inferred from the time, Li Lihong was killed between [-] o'clock in the afternoon on Christmas Eve and before [-] o'clock in the morning of the next day. It took at least seven to ten hours for the murderer to dismember the body. Calculated according to the shortest time, the time when Li Lihong was killed That is before midnight on Christmas Eve.

Li Lihong's house is an old-fashioned anti-theft door. You don't need to open the door to clearly see the people outside the door. Just ask, who would let a person wearing a full-body waterproof suit enter the door without any doubt? ?

"What did the monitoring find?" Zhang Zimu asked.

Chen Han stood up and said: "After Li Lihong left Rainbow Mall at [-]:[-] p.m. A black plastic bag."

Zhang Zimu turned his head and asked Pan Qingyue, "Did you find that black plastic bag at the scene?"

Pan Qingyue looked at the information in his hand and said, "Yes, there is a black plastic bag in the trash can in the kitchen, which once contained fish. In addition, there is an uncooked sea fish in the refrigerator."

There seemed to be no problem with this, but Zhang Zimu frowned after hearing it.

Originally, there was an event in Rainbow Mall that day, and Li Lihong would rather go back quickly if she had a bad fight with her colleagues, but why did she spend time buying fish on the way, and didn't cook it when she bought it back?

Zhang Zimu was not the only one who thought of this question, Zhong Yiyan said: "Could it be that I wanted to cook it for someone, but when that person came, he killed her?"

"Probably not," Cui Xiaoyu shook his head and said, "When you cook at home, you usually start cooking before the guests come. There is no movement in the refrigerator."

"Cui Xiaoyu is right. The weather is cold now. If you want to cook the dishes, you don't need to put them in the refrigerator. Besides, the sea fish has a strong smell. Before cooking, you should marinate them with green onion and ginger cooking wine. Put them in the refrigerator. I haven't planned to do it yet." Li Cancan added next to him.

Since I didn't plan to do it, why did I buy it on the way home in a hurry?

"Zhong Yiyan will visit the market tomorrow to see if Li Lihong bought anything other than fish that day," Zhang Zimu said.

"Yes, Captain!"

Dong Jiajie stood up and said: "It has been confirmed that Li Lihong's four boyfriends had alibi on that day, and several other male colleagues who are said to have an ambiguous relationship have also confirmed their alibi.

But there is one thing that is a bit strange. Two of the men, Fang and Li, both mentioned the same thing. Every time Li Lihong invited them to spend the night at home, they only slept in the guest room, and the master bedroom was locked.Fang once wanted to go into the master bedroom, but was refused by Li Lihong, and the two had a big fight over it. "

"Master bedroom?" Zhang Zimu frowned again.

Everyone couldn't help but think carefully about the situation in the master bedroom of Li Lihong's house. Pan Qingyue even displayed the photos they took in the master bedroom on the monitor screen one by one. Nothing special to pay attention to.

"Wait a minute, what is that?" Sun Liang looked at one of the photos and shouted.

It was a photo of the wall, and besides the bloodstains, there was a light white mark on it, which seemed to be only about one centimeter wide.

"This is the mark left by the partition." Pan Qingyue had investigated this time before, and he called up another photo, which was the opposite wall, and there was also such a white mark on it, and said: "Because there are two rooms and one room. In the living room, Li Lihong's parents used wooden boards to divide the master bedroom into two rooms. Li Lihong slept inside and her brother slept outside. Later, her brother left home to go to study in country F before tearing it down. This is the trace left by the board. .”

"That is to say, the current guest room is the former bedroom of Li Lihong's parents?" Sun Liang asked.

"Yes."

Everyone finds it a little weird. Generally speaking, when you bring someone home for the night, you will take them to your own room, not to your parents' room. Even if your parents have gone abroad and don't live in that room, the children will not do this Why did Li Lihong do the opposite?

"Could it be that women are different from men?" Huang Xiaoshi said stupidly.

Cui Xiaoyu and Li Cancan slapped him on the head at the same time.

"Tomorrow, we will focus on re-inspecting the master bedroom." Zhang Zimu said to Pan Qingyue.

"Yes, Captain!"

Zhang Zimu turned his head and said to Sun Liang: "Did you find anything when you went to the university today?"

Sun Liang recounted the information he got at the university, and then said: "Captain, although everyone says that Yang Yuxin committed suicide by jumping off a building, I always feel that this matter has something to do with Li Lihong, and it's not just a matter of two women competing for one man." , and I also doubt why Li Lihong is the man who refuses to speak out."

Zhong Yiyan said from the side: "It's been ten years, so it's unlikely that Yang Yuxin's family will come to take revenge?"

"I have no doubts about Yang Yuxin's parents." Sun Liang shook his head.

There are usually two situations for revenge. One is to cut the mess with a sharp knife, such as stabbing to death with a knife, or to make the enemy feel the same pain. If this is the case, Li Lihong should be pushed down from the upstairs instead of killing Li Lihong to pieces.

Yang Yuxin's parents are both five or sixty years old. Although Yang Yuxin still has a younger brother, her parents adopted her after she died. This year, she is only nine years old. It is basically impossible for Yang Yuxin's parents who have adopted a son to come back. He came to seek revenge on Li Lihong, and even committed murder and mutilated corpses.

"I doubt...whether this man really exists." Sun Liang said.

Everyone was stunned.

"Why do you say that?" Zhang Zimu tapped his fingers on the table a few times.

Sun Liang took a deep breath, as if he was looking for some confidence in what he was going to say next, and he said: "I asked five of Li Lihong's classmates, one dormitory supervisor, two teachers, and all of them said 'I don't know. Who is this man', Du Jinxin also told me that a group of boys organized to find this man at school, but they failed, which also indirectly shows that the man is not a teacher or student of the school, and is probably an outsider. person.

In addition, the dormitory supervisor told me that Li Lihong and Yang Yuxin were living on campus at that time, and the school building regulations of Binhai University ten years ago were that all students living on campus must live on campus from Sunday to Friday night, and the school building is locked at 10:30 p.m. , turn off the lights at [-] o'clock, only on Saturdays can you stay away from school.Every night, the dormitory supervisor checks before turning off the lights, and if the regulations are violated, a demerit will be recorded.

According to the dormitory supervisor’s recollection, Li Lihong and Yang Yuxin never had a record of violating the rules during their stay at the school. That is to say, if the man was outside the school, both Li Lihong and Yang Yuxin would only see him on Saturdays. "

Hearing this, everyone understood.

There are two prerequisites here:

One, there is such a man;

Two, this man is an outsider.

According to various feedbacks, both Li Lihong and Yang Yuxin can only meet this man on the same day, and when boyfriend and girlfriend are dating, it is usually difficult to fix the time, especially when they can only meet once a week, even if they hang out for a whole day, it is not enough Strange, unless the man can hug Li Lihong and Yang Yuxin at the same time, he can't arrange the time at all.

In other words, this "cheating man" probably does not exist at all, or Yang Yuxin's suicide has nothing to do with the "cheating man".

That's why Li Lihong refused to tell who that man was.

Sun Liang also came to this conclusion after synthesizing all the materials.

Zhang Zimu knocked on the table a few times with his fingers, and said, "When you mentioned the suicide case of jumping off the building, is there any connection with the current murder case?"

Sun Liangliang nodded and said, "Yes, because December 24th is Yang Yuxin's birthday."
