Criminal Investigation Notes

Now that we are here, the waiter brought their lunch.

For a while, the central hall was filled with the smell of food.

Song Wen looked at the time, and it turned out that it was past eleven.

Qiu Lan hurriedly gathered the Tarot cards placed on the table.

The meal on board was just a simple meal. Song Wen was very used to eating, but Lu Siyu was picky and frowned while eating, and finally only barely ate half a plate.

After a meal, everyone became more familiar.

Qiu Lan took out the phone and acted coquettishly to add everyone's WeChat. She first ran to add the couple, and then turned back to ask Lu Siyu and Song Wen.

Song Wen looked at this cheerful little girl with a little helplessness. She didn't seem to be going to do academic research, but she was like traveling. He and Lu Siyu went over, but there was business to do.

Lu Siyu didn't say anything, he took out the phone openly and opened the QR code for her to scan it.

Song Wen also pretended not to know him and swept away.Then I saw that this kid was missing to play the full set. The WeChat ID is brand new, with a mobile phone number bound to it, and there is no friend.Guai had to be afraid of adding WeChat, so I changed back, and even deleted it.

Song Wen didn't have a trumpet that he could spare at any time, so he could only make his circle of friends invisible, actively scanned them, and added two female students.

Then Qiu Lan specially pulled a group called Nansha Island Typhoon Expedition Group.

There were a total of seven people in the group, and it seemed that everyone was pulled in.

Song Wen recognized it, and there was a person with the sky as his head, which looked like Teacher Su.

In the blink of an eye, more than half of the journey has passed, and the hull shook more violently. The typhoon finally had some clues, and the sky gradually became darker, unlike the clear sky before.

Lu Siyu was a little seasick after eating. In addition, he had talked too much with Song Wen before, and now he did not want to speak. He put his body on the armrest of the sofa and listened to them quietly.

The two girls started to talk about the itinerary of the trip again in twitter.

They checked the latest weather forecast. The typhoon is expected to reach Nansha Island tonight and will not leave until tomorrow morning.That is tonight, they all need to hide in the hotel.

After the typhoon, the weather will get better. It will be sunny for several days. This time their trip on the island will last seven days. Apart from doing some scientific research, the rest of the time will be good enough for fun.

Qiu Lan asked Jiang Jiang: "By the way, did you bring your swimsuit? Maybe the weather gets better and you can go swimming in the sea."

Jiang Jiang's eyes gradually widened: "Do you dare to go down? I heard that there are sharks in this sea area."

Qiu Lan refused to believe: "You are lying to me? This is an offshore island, how come there are sharks?"

Jiang Jiang said: "Of course there is, or how did you think the name Nansha Island came from? How did you pass the marine biology class?"

Teacher Su heard them arguing and began to teach the students: "This is not the main activity area for sharks, but there are still some sharks, such as shortnose dogfish, longnose dogfish, and shadow woolly sharks. They mostly live on the outer edge of coral reefs, or 120 meters underwater, and only occasionally surface. In the past, it was said that there were sharks on the island and some fishermen disappeared as a result, so this island got the name."

Then Teacher Su added another sentence, “Recently it’s October. The number of tourists on the island has decreased. Even after the typhoon has passed, the seaside here is not very safe. Moreover, the sea is cold and it is easy to cramp and run into danger. Still don't go swimming in the water."

Qiu Lan then dispelled the idea of ​​swimming.

When Jiang Jiang heard this, his eyes moved, and he looked at Teacher Su and said, "By the way, when I came to the island, my mother was a bit reluctant to come over. I said I was going with my teacher and classmates. , She let me come."

Qiu Lan was surprised: "Why?"

For this trip, Qiu Lan's family fully supported it.

This time, they mainly helped Teacher Su record data, provide assistance, and help teachers organize information. Therefore, the expenses of this line are reimbursed by school research funds, which is equivalent to traveling at public expense. If Teacher Su writes and publishes the paper in the end, they can still Signed later.

With this kind of experience, the postgraduate entrance examination can also leave a good impression on the interviewing teacher. In all, the advantages outweigh the disadvantages.

Seeing that other people didn’t seem to know Jiang Jiang, Qiu Lan asked him several sentences before hesitatingly said: "My mother told me that a girl had disappeared on this island. So at the beginning she and my father were afraid It's not safe here, so I don't want me to come." She also heard from Teacher Su that the fishermen had disappeared in the past and then remembered this.

Song Wen asked casually: "The girl is missing? Is this true or a rumor?"

These islands, scenic spots, historical sites, etc., often have some rumors that are spread by people, and they become indistinguishable from the real and the fake. And the more haunted, the stranger the place, the more popular it is to travel.

Jiang Jiang said: "It's true. I'm not making up stories, and it's not a long time ago, it's just two months ago. After listening to my mother's words, I also searched the news to see it. You all Do not you know?"

Several other people shook their heads, obviously not clear about it.

Qiu Lan asked: "You can tell us something, you can be more careful when you look back."

Jiang Jiang hesitated and said: "Well, I also read the news. It should be at the end of August, at the end of the summer vacation this year. There was a female student about our age who came to this island to play. At that time, she was still traveling. During the peak season, there are more tourists on the island. By the way, you know, there is only a slightly larger B&B hotel on the island, called Happy Hotel, where all tourists on the island live."

Qiu Lan said, "I know that we booked there this time. Only that one can be booked online. There are about 20 rooms in total. There is also a story about this hotel. The wealthy businessman took a fancy to this island and thought it was a paradise, so he built a holiday villa for himself. At that time, many materials and craftsmen were drawn from far away. Later, this rich man The merchants fell in the middle of the road, and a line of his descendants remembered the island, so they moved over and converted the villa into a hotel to make a living."

Jiang Jiang nodded: "Yes, this hotel will be full during peak tourist seasons. The girl checked into the Happy Hotel in the summer. A few days later, the hotel owner called the police that the girl was missing. Later, in the hotel, the police They found the girl’s credentials and all her luggage. They found the girl’s mobile phone at the seaside. The last message on the mobile phone was a group text message sent by the girl. Of course, the police had not disclosed the entire content of the text message, except that the last sentence was: "Sorry, I want to say goodbye to this world.""

Qiu Lan blinked and asked, "Is that girl committing suicide?" This sentence sounds like a standard suicide line.

"I don't know too much. After that, the girl disappeared, no one was alive, no corpse was seen, the police searched for a long time, but she was not found."

Jiang Jiang continued, "I see people gossiping on the Internet, and it seems that the girl's parents exposed some details to the marketing accounts and the media, hoping that people can help find the truth about the girl's disappearance."

Qiu Lan said, "Is there anything hidden in it? Or is there something strange about the girl's disappearance?"

Jiang Jiang pursed his lips before continuing to say: "That's... logically speaking, the message should be sent to her relatives and friends, but then according to the girl's parents, the message she sent did not notify her father. "

Qiu Lan frowned, completely unable to figure out: "Why is this?"

Jiang Jiang's eyes deepened: "There is an analysis by netizens on the Internet, saying that it may be because someone copied her address book before and defrauded her parents. The girl's father's name was not recorded in the address book. In the past, every time she called her family, she would silently silence her number. And this short text of suicide note, even her mobile phone sold out, express delivery, etc., just happened to not be sent to her father. Two days before the girl disappeared, she also called her parents separately to share her itinerary. At that time, she was very happy to say that the island is very fun. How could such a person commit suicide?"

Erasing the names of the closest people in the phone address book is a way to prevent fraud, and many people do.Obviously, the person who sent this text message did not know this situation.

Hearing this, Song Wen was engrossed, and even Lu Siyu on the side opened his eyes.They keenly felt that this missing story seemed to be not simple.The couple also listened attentively, and Teacher Su also helped his glasses and listened to his students.

Lu Siyu once followed Wu Qing on a project, which was to analyze various suicides and pretended suicide cases and summarize the regular characteristics.

The so-called suicide refers to the dangerous behavior of individuals deliberately and voluntarily by various means to end their lives under the influence of complex psychological activities. It is a complex social phenomenon.

Every tens of seconds on the earth, one person commits suicide.

In the eyes of ordinary people, suicide is suicide, it is nothing more than a different method.In the eyes of these "professionals", suicide has many ways.

Is a person committing suicide?What is the motive for suicide?What is the method of suicide?

As the police, how to prevent suicide, how to rescue various ongoing suicides, and how to prevent infectious and imitative suicides is a complicated subject.

Suicide-related cases often contain many clues, which are the unique death codes of suicides.

Domestic scholars generally divide suicide into emotional suicide and intellectual suicide.

Emotional suicides are mostly jumping from buildings, jumping bridges, traffic accidents, etc., and most of them have encountered some fierce conflicts or major setbacks before committing suicide, and they were carried out under irritability, shame, regret or anger.

This method of suicide progresses rapidly and the development period is short, which is difficult to prevent.

Most emotional suicides will have obvious contradictory stages, and will release signals of suicide attempts, which are easier to confirm.

Reasonable suicide is a gradual intent to kill. It is purposeful and planned. The process of suicide is slow and the development cycle is longer.

For people who commit suicide rationally, suicide is a solemn decision. The idea of ​​suicide has been brewing in the mind for a long time, and there are early signs.

Generally, people who commit suicide rationally will wear their favorite clothes, eat a full meal, use soft cloth, or a more suitable method.They will try, simulate repeatedly, think about the process repeatedly, and use idiomatic methods.

Regardless of the method of suicide, most suicides who are not mentally ill hope that they can face death calmly.

In similar cases, suicide last words are not the criterion for suicide. Last words are easy to forge. It is important to explore the psychology of the deceased and restore the suicide process.

In many cases, because the deceased cannot speak, some homicides can easily be disguised as suicide cases. At this time, the police need to be able to observe the details.

For example, left-handed people rarely commit suicide with their right hand. People who hang themselves usually do not use very thin wire or silk thread. If there is blood stains, the blood stains generally fall into a line naturally, rarely splashing everywhere...

Those suicides that do not conform to the law of suicide seem to be full of loopholes and doubts in the eyes of experienced police.

When Lu Siyu was an intern, he encountered a case in which a husband committed suicide by burning charcoal after being drunk, leaving a suicide note on the table.When he arrived at the scene, he quickly discovered that it was actually homicide.The reason is simple. The charcoal basin was wiped clean, without a fingerprint.

My husband is already drunk and decides to commit suicide in this situation. How can he wipe his fingerprints?

After investigation and questioning, it turned out that it was the wife of the deceased and the suicide note was also forged.

Just like the story that Jiang Jiang tells now, if the girl has no motive for suicide and no abnormal behavior before, it is very likely that the last words are not left by her. The girl may have suffered an accident for other reasons.

Outside the cabin, the typhoon has started, and the whistling wind can be heard, the sky is half clear, and there is only Jiang Jiang's voice in the middle hall. It is the story of the girl's disappearance, which makes people feel a bit chilly.Lu Siyu tightened his coat tightly and continued to listen to Jiang Jiang.

Qiu Lan frowned and said, "Then...this last text message is probably not sent by the girl herself? And the person who sent this message didn't know that her father's phone number was not saved in her mobile phone address book."

Jiang Jiang nodded, the same is true of the online analysis she read before.

Song Wen couldn't help but leaned forward and asked: "Then what happened to the police investigation?"

Jiang Jiang said: "The police questioned the tourists on the island at the time, the owner of the hotel, and other related people. They all knew nothing about the girl's whereabouts. According to many people's reactions, the girl was still in the hotel the first day and everything went as usual."

"The owner said that as soon as the shop opened in the morning, she saw her leave the hotel and went to the beach. Some people online suspected that the girl was involved in a pyramid scheme, and some suspected that the girl met a bad guy. Others suspected that the people in the hotel and the boss were in the collective Lying. The news I read only said that the police confirmed that the matter has nothing to do with pyramid schemes, and they are trying their best to search for the missing girl."

Qiu Lan sighed: "But the girl's family can't accept this result, right?"

Jiang Jiang nodded: "Yes, the family members posted on the Internet that there were some doubts. The first doubt was the text message suicide note. The second doubt was that after the girl arrived on the island, she was originally scheduled to return two days later. I changed the departure time here twice and stayed on the island for five days. When living here, her family urged her to go back many times, but she was stalled immediately and did not leave. Doubt three, the girl went to the island Before, she had exchanged a lot of cash, but among the relics that were finally packed, she had only a small amount of cash in her luggage. On this closed island, did she carry the money with her or where she spent it? Go? Or was it snatched away?"

"Is there anything on the island that attracts her? Or is she dating online? It's also possible... to make money and kill?" Qiulan's brain opened wide and asked continuously.

Jiang Jiang shook his head and said, "Then I don't know much."

Song Wen was silent when he heard here. Nansha Island is an island. There are not many aborigines on the island. He also checked before coming. There is no police station on the island. There is only a pier police office on the pier. The police are still in rotation on several islands, not often here.

The nearest branch nearby should be the Xinchuan branch on the shore, but there are only a dozen criminal police officers, and the police force is limited.

The island is different from the cities and villages, and there are many dead spots. The vast sea on all sides is enough to make a person disappear.

Under such circumstances, it is certainly impossible to properly investigate the disappearance of the girl.

It is precisely because of this that fugitives like Wu Hongyou can hide on this island for so many years.

Seeing that he was silent, Lu Siyu seemed to know what he was thinking, and he whispered to everyone: "Even if you want to find things during the summer vacation, it is probably impossible to start."

The police announcement stated that the search will be carried out fully, but there will be a time limit for this search. The longer the interval, the less likely it is to find it.

Qiu Lan turned his head and asked the couple: "Don't you go to the island often? Haven't you heard of this thing?"

Chen Zui said: "Do you know the girl's name? We don't know whether we know this girl without a name or a surname."

Jiang Jiang thought about it for a while: "It seems to be Zhao, who is used in the news."

Amy shook her head: "I haven't heard of it."

Chen Zui said: "The girl probably encountered some accident when she went out to play? Maybe she went out to swim and drowned?"

Song Wen pointed out the loopholes in one sentence, "The mobile phone was picked up at the beach, how can you not take good care of your valuables while swimming."

Chen Zui was asked to stop by him, and said haha: "This is just gossip. Discuss with each other. Don't be so serious! That mobile phone message...maybe it was sent by the store manager or someone. I think the purpose is to send it. , I want to avoid responsibility. If the girl commits suicide, probably they think everyone is happy, and the police will not need to pursue it."

At that time, those who sent text messages did not expect that it was this text message that made the whole thing even more confusing.

Amy also nodded and agreed with Chen Zui's opinion: "Even if the girl had reported peace with her family before and said that she had a good time, it may not prove that she did not die by suicide. She may also be suffering from depression. , Sudden onset or emotional instability, it is possible."

Several people were chatting here, and the ship suddenly moved violently.

"Dear travelers, we are about to enter the stormy area, but there are still twenty minutes before we reach Nansha Island."
