Criminal Investigation Files

At this point, the waiter brought over the lunch they had ordered.

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

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

Qiu Lan hurriedly gathered the tarot cards on the table.

The meals on the boat were just simple meals, and Song Wen was very used to eating, but Lu Siyu was picky and picky, frowning while eating, and finally managed to eat only half of the plate.

After a meal, everyone became more familiar with each other.

Qiu Lan took out her phone and coquettishly wanted to add everyone on WeChat. She first ran to add the couple, and then turned around to ask Lu Siyu and Song Wen.

Song Wen looked at this elated little girl helplessly. She didn't seem to be going to do some academic research, but she seemed to be going on a trip. He and Lu Si talked to each other, but they had business to do.

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

Song Wen also pretended not to know him, and took advantage of the situation to scan.Then I saw that this kid was really missing to play the full set, this WeChat ID was brand new, it was bound to a mobile phone number, and he didn't have a single friend.No wonder I have to be afraid of adding WeChat, and changing it back later, even deleting it is easy.

Song Wen didn't have a spare account at any time, so he could only make his Moments invisible, took the initiative to scan theirs, and added the two female students.

Then Qiu Lan specially organized a group called the South Shark Island Typhoon Expedition Group.

There were a total of seven people in the group, and it seemed that they had drawn everyone into it.

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

More than half of the trip had passed in a blink of an eye, the ship was shaking more violently, the typhoon finally had some clues, and the sky was gradually darkening, not as clear as before.

Lu Siyu was a little seasick after eating, and he had talked too much with Song Wen before, so he didn't want to speak now, so he leaned his body on the armrest of the sofa and listened to them quietly.

The two girls chattered again and started talking about the itinerary of this trip.

They checked the latest weather forecast. The typhoon is expected to arrive at 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, and it will be sunny for several days. This time, their trip to the island will last seven days. Except for some scientific research, the rest of the time is enough for fun.

Qiu Lan asked Jiang Jiang: "By the way, have you brought your swimsuit? Maybe when the weather gets better, 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 it: "Are you lying to me? This is an offshore island, how could there be sharks?"

Jiang Jiangdao: "Of course, otherwise, how do you think the name South Shark Island came from? How did you pass the marine biology class?"

Teacher Su heard them arguing, and taught the students: "This is not the main activity area of ​​sharks, but there are still some sharks, such as short-nosed dogfish, long-nosed dogfish, and shadow velvet 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 near the island, and some fishermen disappeared because of it, so this island got its name."

Then Teacher Su added, "It's October recently, and the number of tourists on the island has decreased. Even after the typhoon has passed, the seaside here is not very safe. Besides, the sea is cold, and it is easy to get cramps and danger. You'd better Still don't go into the water for a swim."

Only then did Qiu Lan give up the idea of ​​going swimming.

When Jiang Jiang heard this, his eyes moved, and he looked at Teacher Su and said, "By the way, speaking of it... When I was going to the island, my mother was a little reluctant for me to come. I said that I would go with the teacher and classmates. , she let me go."

Qiu Lan was surprised: "Why?"

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

This time they are mainly helping Teacher Su to record data, provide assistance, and help the teacher sort out the materials. Therefore, the expenses for this line of work are reimbursed by the school’s scientific research funds, which is equivalent to public travel. Post signature.

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

Seeing that no one else seemed to know about it, Jiang Jiang was questioned several times by Qiu Lan before he hesitated to speak: "My mother told me that a girl was missing 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 fishermen disappeared in the past before she remembered it.

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

These islands, scenic spots, historical sites, etc., often have some rumors, which are passed on by people, and it becomes difficult to distinguish between true and false, and often the more haunted and strange the place, the more popular the tourism.

Jiang Jiangdao: "It's true, I'm not making up a story, and it wasn't a long time ago, it was just two months ago. After I heard what my mother said, I searched for the news. You all Do not you know?"

Several other people shook their heads, apparently not knowing about it.

Qiu Lan asked: "Tell us about it, and you can be more careful when you look back."

Jiang Jiang hesitated for a moment and said: "Well, I also read the news, it should be at the end of August, when this year's summer vacation is about to end, a female student who is about our age came to this island to play, and it was still a tourist at that time. During the peak season, there are more tourists on the island. By the way, you know, there is only one slightly larger B&B hotel on the island, called Happiness Hotel, and all the tourists on the island live there."

Qiu Landao: "I know, that's where we booked this time. Only that one can be booked through the Internet. There are about twenty rooms in total. There is another story about this hotel. More than ten years ago, a The rich businessman fell in love with this small island and thought it was a paradise, so he built himself a holiday villa. At that time, many materials and craftsmen were pulled from far away. Later, the rich man The business was in decline, and a line of his descendants thought of this small island, so they moved here, and even converted the villa into a hotel to make a living."

Jiang Jiang nodded: "Yes, this hotel will be full during the peak tourist season. The girl stayed at the Happiness Hotel in summer. A few days later, the hotel owner called the police and said that the girl was missing. Later, in the hotel, the police They found the girl's ID and all her luggage. They found the girl's mobile phone at the beach. The last message on the mobile phone was a group text message sent by the girl. Of course, the police did not disclose the full content of the text message, only the last sentence was: 'Sorry, I want to say goodbye to this world.'”

Qiu Lan blinked and asked, "Did that girl commit suicide?" It sounded like a standard suicide line.

"I don't know too well. Anyway, after that, the girl disappeared. There was no one alive or dead. The police searched for a long time, but they couldn't find her."

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

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

Jiang Jiang pursed her lips before continuing, "That's right... Logically speaking, the message should be sent to her relatives and friends, but according to the girl's parents, she didn't notify her father of the message she sent. "

Qiu Lan frowned, completely puzzled: "Why?"

Jiang Jiang's eyes became darker: "There is an analysis of netizens on the Internet, saying that it may be because someone copied her address book before, and then defrauded her parents. The girl's father's name is not recorded in the address book. In the past, every time she called her family, she kept silent on the number. And this short suicide note text message was sent to her mobile phone for takeaway, courier, etc., but it happened to not be sent to her father. And two days before the girl disappeared, she called her parents separately to share her itinerary, and at that time, she said very happily that the island was very interesting, how could such a person commit suicide?"

Erasing the names of the closest people from your phone contacts is a way to prevent fraud, and many people do.Apparently, the person who sent this text message was unaware of this situation.

Hearing this, Song Wen was so engrossed that even Lu Siyu who was beside him opened his eyes.They are keenly aware that the story of this disappearance does not seem to be simple.The couple was also engrossed in listening. Teacher Su also adjusted his glasses and listened to his students.

Lu Siyu once did a project with Wu Qing, which was to analyze various cases of suicide and fake suicide, and summarize the regular characteristics.

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

Every tens of seconds on earth, someone commits suicide.

In the eyes of ordinary people, suicide is suicide, nothing more than a different method.In the eyes of these "professionals", there are many ways to commit suicide.

Does a person commit suicide?What was the motive for the suicide?What is the method of suicide?

As the police, how to prevent suicide, how to rescue various suicides in progress, and how to prevent contagious and imitative suicides are complex topics.

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

Domestic scholars generally divide suicide into two types: emotional suicide and rational suicide.

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

This kind of suicide process is rapid and the development period is short, so it is difficult to prevent.

Most emotional suicides will have a stage of obvious conflict, which will release a signal of suicide attempt, which is relatively easy to confirm.

Rational suicide is a killing intent that sprouts gradually, with a purpose and a plan. The process of suicide is very slow and the development cycle is long.

For those 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 put on their favorite clothes, have a full meal, use soft cloth strips, or a more suitable method.They will try, iterate and simulate, iterate the process of thinking, and they will use the usual methods.

Regardless of the suicide method, most non-mentally ill suiciders hope that they can face death calmly.

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

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

For example, left-handed people seldom use their right hand to commit suicide, and people who hang themselves usually do not use extremely thin iron wire or silk thread. If there is blood stains, the blood stains usually fall naturally into lines, and rarely splatter everywhere...

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

Back then when Lu Siyu was an intern, he encountered a case where a drunken husband committed suicide by burning charcoal in his own home, leaving a suicide note on the table.When he arrived at the scene, he quickly discovered that it was actually a homicide.The reason is simple, the charcoal basin has been wiped clean without a single fingerprint.

The husband was already drunk and decided to commit suicide under such circumstances, how could he wipe off his fingerprints?

Later, after investigation and questioning, it turned out that it was the wife of the deceased who did it, and the suicide note was also forged.

Just like the story Jiang Jiang told now, if the girl did not have any motive for suicide and had no abnormal behavior before, it is very likely that the last words were not left by me, and the girl may have already suffered an accident due to other reasons.

Outside the cabin, the typhoon had already started, the whistling wind could be heard, the sky was half-lit, and Jiang Jiang's voice was the only voice in the middle hall, telling the story of the girl's disappearance again, which made people feel a little chilly for a while.Lu Siyu tightened his jacket and continued to listen to Jiang Jiang.

Qiu Lan frowned and said, "Then... the girl probably didn't send this last message? 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 was true of the online analysis she read before.

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

Jiang Jiangdao: "The police questioned the tourists on the island at that time, the owner of the hotel, and other relevant people. They didn't know anything about the girl's whereabouts. According to many people's reports, the girl was still in the hotel the first day, and everything was as usual."

"The shopkeeper said that he saw her leave the hotel as soon as he opened the shop in the morning and went to the beach. Some people on the Internet suspected that the girl was caught in a pyramid scheme, and some people suspected that the girl had encountered bad people. Others suspected that the people in the hotel and the boss were collectively Lies. The news I read only said that the police confirmed that the matter had nothing to do with pyramid schemes, and they are doing their best to search for the missing girl."

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

Jiang Jiang nodded: "Yes, the family members said on the Internet that there are several doubts. The first doubt is the suicide note in the text message. The second doubt is that after the girl arrived on the island, she was originally scheduled to return in two days. I changed the departure time twice here, and lived on the island for five days. When I lived here, my family urged her to go back many times, but she kept prevaricating and did not leave. The third doubt is that the girl went to the island Before, she had exchanged a large amount of cash, but among the relics she packed up, there was only a small amount of cash in her luggage. On this closed island, did she take the money with her or where did she spend it? Did it go? Or was it snatched away?"

"Is there something on the island that attracts her? Or is she in an online relationship? Or maybe... murdering her for money?" Qiu Lan's mind was wide open, and she kept asking questions.

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

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

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

Different from cities and villages, the island has many dead spots, and the vast sea water on all sides is enough to make a person disappear.

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

It was also because of this that fugitives like Wu Hongyou were able to hide on this island for so many years.

Seeing his silence, Lu Siyu seemed to know what he was thinking, and said softly to everyone: "Even if you want to find out about the summer vacation, you probably won't be able to find it."

The police announcement said to search with all their strength, but there will also be a time limit for this search. The longer the interval, the less likely it will be found.

Qiu Lan turned to the couple and asked, "Don't you often go to the island? Have you never heard of this?"

Chen Zui said: "Do you know the girl's name? We don't know if we know this girl who has no name or surname."

Jiang Jiang thought about it for a while: "It seems that the surname is Zhao, and Zhao XX 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 by herself? Maybe she drowned while going out swimming?"

Song Wen pointed out the loophole in one sentence, "The mobile phone was picked up at the seaside, how could swimming not take good care of your valuables."

Chen Zui was stopped by his question, and he yelled: "This is gossip, let's discuss it with each other, don't be so serious! That text message...maybe it was sent by the store manager or someone else. I think the purpose of sending it is , I want to avoid responsibility. If the girl committed suicide, they probably think everyone is happy, and the police don’t have to pursue it any further.”

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

Amy also nodded to agree with Chen Zui's opinion: "Even if the girl reported her safety to her family before and said that she played well, it may not be able to prove that she did not commit suicide. She may also have depression or something. , Sudden onset or emotional instability are all possible."

Several people were chatting here when the boat suddenly moved violently.

"Dear passengers, we are about to enter the wind and wave area, but we will reach South Shark Island in 10 to [-] minutes."
