Criminal Investigation Notes

Then Lin Xiuran pulled out his finger and continued: "If the puncture is in the heart, the deceased may be killed within a few minutes, and there is no time to rescue. This may be the cause of death of the deceased, but because of the lack of internal organs, we cannot rule out other causes of death. For example, it may also be possible. Hemorrhage shock caused by abdominal organs, it may also be caused by a knife pierced an artery in the neck, or death caused by other reasons. Moreover, based on the marks on the bones, we can not be sure that the stab in the chest is the dead person alive. Stabbed at some time."

Xu Yao added: "I don’t think it’s likely to be a knife in the neck. If the knife is in the neck, there may be a lot of spray-like blood stains, but we did not find a lot of blood reaction on the blood jackets that were cut and washed. This is not very consistent."

Lin Xiuran explained: "The above is just a forensic inference. This is the main finding of the corpse. The others are unrelated. For example, there is no bleeding in the back, no injury in the skull, no fracture of the hyoid bone, and no other injuries on the body. This corpse is severely mutilated, so forensic autopsy alone cannot obtain more information."

Lin Xiuran finished packing up the relevant pictures, and after finishing packing, he concluded: "I will sort out my findings for everyone. Judging from the condition of the body, the time of death of the deceased was from 6 pm to 12 pm that day. During this time, because I was soaked in ice water and lost important information, I couldn’t make the time of death more specific. The cause of death was suspected to be a knife pierced the heart in the chest. I think this may be a crime committed by an acquaintance, not serial. In the case, judging from the cutting edge, there should be only one person who dismembered the body. The strength is not very strong. It is certainly not a strong man, but it cannot be very thin, at least an adult with independent behavior. The murderer has a certain degree of human body and organs. Understand, there may be a certain medical basis."

Lin Xiuran turns 30 this year, which is the golden age of forensic medicine, a time of both rich experience and vigorous energy.Calm and calm, clear logic, and no nonsense forensic doctors can solve cases with less effort.After the analysis, everyone has some new understanding of the case.

"I used to call up the monitoring route here. Although there is no complete picture, it is basically certain that the deceased went home at around 8:30." Zhu Xiao gathered various clues to supplement the timeline.

Xu Yao also summarized the physical evidence information: “In terms of physical evidence, the previous physical evidence forms have been sorted out. As Director Lin discovered, the deceased was living together, that is, there was a person in the house. Hair obtained from combs and pillows After comparing the result with the DNA extract, it was confirmed that it was the same person. There were many traces in the house, doorknobs, toilets, restaurants, fingerprints everywhere, and we also obtained a knife from the knife thrown along with the corpse. The clear fingerprints are consistent with some fingerprint traces in the house."

Having fingerprints is undoubtedly good news. Song Wen asked: "Where is the fingerprint retrieval process?"

"Gu Bureau there."

Now that the second-generation ID card has obtained most of the fingerprint data, it just needs to go through an approval process.After comparing with the household registration information, you can know the identity of this person.

"There are fingerprints on the murder weapon, can we identify the suspect?" Fu Linjiang asked.

Lao Jia nodded and said, "This person disappeared after the incident. I guess he was hiding. I thought this case would be difficult. Looking at it now, solving the case is just around the corner."

"Let me see the murder weapon again." Song Wen stretched out his hand and asked for the evidence. Xu Yao handed him an evidence bag with a blood-stained knife in it.

Song Wen looked up and down and put forward different opinions: "I think this may not be a murder weapon. Based on the two gaps in the ribs just now, we can get the width of the murder weapon, or simulate the shape. A double-edged knife can It forms a wound like that. This knife may just be a knife for dismembering the corpse."

Lin Xiuran took the knife and looked at it and nodded, "Yes, such a knife can only form a scar on a single rib. It does not match the knife mark on the chest."

"Is it possible that the murderer stabbed the deceased with this knife, the abdomen was stabbed, and the knife in the chest was made up by another weapon?" Fu Linjiang proposed another hypothesis.

Song Wen lowered his head and thought for a moment, then shook his head: "It's a bit too complicated. The analysis of the case is up to this point. I don't understand some parts of it. The bodies are destroyed in this way. Is it meaningful to cover up the cause of death? When wearing gloves, but leaving fingerprints and blood stains on a missing murder weapon, this is not reasonable. The murderer had to deal with the corpse all day yesterday. Now that he wears gloves, he should clean up all the clues. The murderer did not deliberately deal with fingerprints in other rooms, and still left traces on the murder weapon, which is inconsistent with his usual cautious behavior."

It was a coincidence that this knife appeared. There were fingerprints everywhere in the room, but nothing was found on the main corpse-slicing tool.Fingerprints and blood stains appeared on the knife thrown following the corpse, many of which were not logical.So that some things seem to be left to them by the murderer.

Song Wen was silent for a moment, with sharp eyes, and said another possibility: "This knife may be deliberately misled by the murderer."

Everyone was silent for a while, in order to mislead the police to judge?So the purpose is to blame Lin Zhenghua's cohabitants?

"What do you think of Lu Siyu?" Song Wen suddenly raised his head and asked.

"Me?" Lu Siyu didn't watch out that he was suddenly spotted, a little surprised, and made a lip licking unconsciously.

Song Wendao: "It's okay, what do you think of."

Lu Siyu flipped through the notebook in his hand and hesitated for a while before speaking, "This case is more cruel. I think the person who dismembered the body has a strong psychological quality, and the method of division cannot rule out a female suspect."

Lin Xiuran nodded: "Because of the same psychology, when a female murderer kills a woman, he abuses the breasts and reproductive organs less frequently than a male murderer. When a male murderer kills a man, he will seldom attack the male organ. This happens in a few cases. , It is also often because the relationship is a rival in love, using this behavior to retaliate emotionally, or it is naturally abnormal."

The angle that Lu Siyu put forward was something that no one had considered before. Song Wen followed his words and thought about it, suddenly wondering what kind of brow raised, and then turned to look at him without comment.

When Lu Siyu noticed Song Wen's gaze, he lowered his head and began to remember something in the notebook.

Fu Linjiang nodded in agreement: "If it's just for killing people, there is no need to do this extra action. It may be more reasonable to mince or stew. Moreover, the murderer used a lot of useless work when handling the corpse."

In other words, such a step is too much to destroy the corpse.The murderer does not seem to care whether others will acquire the identity of the dead.But deliberately concealing wounds and certain things, what logic is this?

Song Wen turned his swivel chair and made a decision: "Anyway, there has been a lot of progress in the case. Even if the cohabitant of the deceased is not the murderer, he must thoroughly investigate. His fingerprint appeared on the relevant knife. , It means that it is also a relevant person. The more information you get, the more helpful it will be to the investigation of the case. Zhu Xiao, you should seize the time to gather the deceased’s information and clarify the identity of the cohabitant. Fu Linjiang, you will continue to investigate the case with Lao Jia. It is necessary for us to see the family of the deceased." He stood up as he said, "That is our other suspect."

Love, this is a 38-year-old housewife, she is Lin Zhenghua's wife.She graduated from Zhongqing Health School and worked as a nurse in cardiothoracic surgery for one year. She married Lin Zhenghua at the age of 22, and gave him a son a year later.Soon after the child was born, Zhongqing quit his job and became a housewife.

In the eyes of outsiders, Lin Zhenghua is an outsider, has a good income, loves the insider, and keeps the family in order. His son Lin Shang has a good academic record and focuses on all the way. This is a happy family.

But in fact, where everyone does not know, they have their own pain.

Song Wen looked at the woman in front of him. She was about 1.6 meters tall. She was a little thin. She was well maintained, her figure was not fat, and she couldn't tell her true age at all, just like a young woman in her early thirties.Now her eyes are swollen, and she is rubbing the corners of her clothes somewhat at a loss.Today, she was notified to claim the body.

After signing a series of orders, Zhongqing was taken to the corpse depository of the funeral home. Lin Xiuran is a professional forensic doctor. Every autopsy is sutured. This corpse is no exception. After the pieces are put together, they can be stitched together. All of them have been treated as much as possible to make the body look less embarrassed.

The cold storage didn't pull away much, only Lin Zhenghua's head was exposed, and he covered his mouth and nodded in love, then took two steps back, tears in his eyes.

Song Wen led her out of the cold storage in the funeral home, and sat in the special lounge to receive family members.Song Wen asked Lu Siyu to pour her a glass of warm water, and then handed her the death certificate.Song Wen has seen too many corpses claiming processes, and everyone's reaction is different, panic, unacceptable, crazy, fainted, and indifferent. In comparison, the woman's reaction is more docile.

"Now that we are investigating your husband's death, can we ask you a few questions?" Song Wen waited for his love to calm down and asked her.This is a routine investigation and one of the work of criminal police.

Lovingly held the water glass in her hand, the temperature that seemed to need hot water gave her strength, then she straightened up and nodded.Her behavior shows that she is a well-educated woman, with restraint in her words and deeds.

Seeing her agreement, Song Wen looked at Lu Siyu and motioned for him to start inquiring.This was the first time that Lu Siyu interrogated the suspect. He looked up at Zhong Lian. He seemed to be a little nervous, and lightly licked his lips and asked, "When was the last time you saw Lin Zhenghua?"

"It was about a week ago. He... didn't go home often. We were basically separated and we lived our own lives." The person is dead, and now it is meaningless to hide those things and pretend to be family harmony.

"Do you know that your husband is living with others outside?" Lu Siyu asked again.

Zhong Qing nodded slightly, "I know, he hasn't touched me since he gave birth to his son. He rented a house all year round outside, sometimes staying outside for several days, and sometimes returning home occasionally. Look at my son." She took a sip of water and continued, "Their circle is quite messy. In the past few years, as far as I know, they have changed several people. What is the name of the most recent one..."

"what is it call?"

Love worked hard and thought about it, spit out a name, "What... Hui."

"Do you think anyone among them wants to kill your husband?"

Love shook his head.

"Then has there been anything unusual recently?"

Zhonglove shook his head again, then nodded as if thinking of something, and said, "But he seems to be a little upset recently. He also borrowed money from me, but the reason is very vague."

"Borrowing money?" Song Wen frowned. The couple really had their own way.

Zhongqing explained: "After we got married, half of his salary was called to me, and he kept the other half of his own. Lin Zhenghua’s salary was not low. In addition to the living expenses of my son and I, I also saved some. Recently He suddenly wanted to ask me to borrow money."

Lu Siyu continued to ask: "Did you lend him?"

Hearing this question in love, he hesitated for a while, lowered his head, like a mosquito hum: "No at first, then...Call him one hundred thousand."

One hundred thousand is another key point. Will Lin Zhenghua's death be due to money?In addition to the money he has on hand, it is estimated that the money is more than that. He asked Zhu Xiao to check Lin Zhenghua's income, which was about 500,000 yuan a year.But for money, why is there no sign of robbery in the house? The victim's cell phone and wallet were not lost.

"From 8pm to 12pm on the day of the incident, where were you and what were you doing?" After showing a look of embarrassment in love, Lu Siyu did not delve into the money issue, but instead asked other questions. .

Love recalled it for a moment, and twisted the bag with her hand. "That night, my son had a cram school. I sent him to it, and it started at 8:30."

"How many make-up students are there in the class?"

"It's a small class with eight people in total."

There are few people in the cram school. If she says she goes, she should not be able to fake it.

"It starts at 8:30 and ends at what time? What were you doing when your son was in cram school?"

"From 8:30 to 10:30 in the evening, two hours of English class. I waited for him at a nearby cafe. As I often go there, the clerk there knows me."

After asking about a dozen questions, Lu Siyu looked at Song Wen, solicited his opinions, to see if there were any questions that he wanted to add, Song Wen asked, "Do you love Lin Zhenghua?"

Love seems to have never expected that the detective captain would ask questions suddenly, and the question was such a sharp question, and the words were lost for a while.

Song Wen received the smile on his usual face, his eyes were calm, and his words were not astonishing, and he continued to ask her: "Married to a homosexual, life is not harmonious. Have you ever thought about divorce?"

Ever since I was asked such a question, I have been reluctant to be placed on the table, making her face flushed: "I...I..."

Song Wen looked straight into her eyes, pressed harder and harder, and then asked her every word: "Don't you hate him?"

Lu Siyu glanced sideways at Song Wen. The man's eyes were sharp as a sword. The question he just asked was relatively gentle, but Song Wen now pointed directly at the core.

Hearing that last question, love suddenly seemed as if a snake was hit by seven inches. The whole person became out of control. Big tears flowed from the corners of the eyes, but they were holding the corners of the mouth and trying to smile. A contradictory expression made her face distorted...
