Criminal Investigation Files

On South Shark Island in the afternoon, with the sea breeze blowing, Song Wen and Lu Siyu stood at a fork in the island and talked with a small stall owner.

This is the end of the only street on the island. If you go further up, you will find a Qingshiya. The Happiness Hotel and Cake House are on the cliff. If you go down a short distance, you will find a beach.

Song Wen took out another hundred from his wallet and asked the little boss, "What else do you know about the girl's disappearance?"

The boss saw the money and then continued: "Speaking of which, it's very evil... That girl liked to eat cakes at that internet celebrity cake shop when she was alive. Not long after the girl died, that is, a month ago, the owner of the cake shop, She passed away." When he said this, he swallowed nervously, "Someone said that the missing girl was already dead, and after her death she became a female ghost, haunting the owner of the cake shop to death. "

Song Wen frowned: "Didn't the police come to investigate these things?"

"Come on, whether it's the girl's disappearance or the owner of the cake shop committing suicide, we've come to investigate."

In order to get back the 100 yuan, the little boss continued to explain in detail, "After the girl disappeared, the police came to inquire and sent people to search the whole island. I also went to check the places where the girl lived, but Nothing was gained. As for the owner of the cake shop, it is said that he committed suicide by cutting his wrist while taking a bath. When he was found, his body was already cold. During that time, there was a storm in the sea, and it took more than a day for the police to come and did not investigate. There's nothing wrong with coming out."

Hearing this, Song Wen understood that this island is far away from the mainland, and it is not easy for professional forensic doctors to come here.

Moreover, the employment of forensic doctors is the same as the employment of doctors and teachers.

The best students and the best elites stayed in provincial capitals or big cities. The average students would go to grassroots cities, remote mountainous areas, island villages, etc. They were the poor students in the class at that time.

With such manpower, such environment, and such conditions, what you expect to be able to find out is rare.

Song Wendao: "It's unlikely that there will be a female ghost. Does the boss have any other reasons for suicide?"

The little boss faltered for a while, then whispered: "There is a saying, it seems that he was cheated by his wife and committed suicide because of anger. But this may be just rumors from the villagers."

"What about the body? Buried?"

"The island has been cremated long ago."

Song Wen frowned, "Why cremation?"

The little boss said: "I don't know if you are from outside. Although our island looks like vegetation and has a lot of beaches, it is actually covered with rocks, and the corpses are not buried deep, so it is easy to be dug out by animals or something. In the past We all do sea burials here, but later it was not allowed, so we had to spend money to transport them out for cremation.”

Lu Siyu asked again: "Then, is the cake shop still open? Who is running it?"

The little boss said: "Although the boss is dead, the proprietress is still there, and the baker in the shop is still there, so it has not been affected. Even the business is better, and young people keep coming here. But there, be careful..."

Having said that, the little boss hesitated to speak.Song Wen asked: "Is there something wrong with the cake shop?"

The little boss quickly waved his hands: "No problem, we also bought the cake on it, it was delicious. There is no restaurant in the Happy Hotel, I guess you have to go there to eat."

I don't know if it's because I really don't know the inside story, or because we are all neighbors, the little boss is unwilling to talk about it.

"Thanks, we will be careful." Song Wen paid the money, and the hundred was also used as a tip.

After shopping, just two steps out, Song Wen's cell phone rang, and he opened it to see that it was Qiu Lan playing him: "Brother Song, are you near the beach? Well, Jiang Jiang and I found it at the beach. Some things, a little scared, can you come and see?"

Then she took a photo and sent it to him, it was a piece of white stuff stuck in the rocks by the sea...

Song Wen frowned, zoomed in on the picture, the white thing was mostly blocked by the reef, and only some shapes could be vaguely seen.

Lu Siyu took his mobile phone, looked sideways and said in a low voice, "I don't see it clearly, it may be a large animal's bone, or... it may be a human bone."

Song Wen stood at a fork in the road and asked Lu Siyu, "We don't seem to be far from the seaside, why don't we go around and have a look?"

Lu Siyu nodded.

Song Wen asked: "The tea eggs..."

Ordinary people would probably say, go back and eat, and there is no rush.

But Lu Siyu is not an ordinary person, he directly took out one from the plastic bag in Song Wen's hand, peeled off the eggshell with his hands, opened his mouth and began to eat while it was hot...

Always eat enough to have the strength to work.

Song Wen took out a tissue to prepare for him, and then put other food in the backpack.

Lu Siyu ate very quickly, and after eating two in a row, some blood returned to his face, and he wiped his hands and mouth with a tissue.

Song Wen then returned to Qiu Lan and said, "Position."

Qiu Lan immediately sent the location, they were at the beach, about 800 meters away from them.

The direction of the beach is well developed for the convenience of tourists. There is an asphalt road leading directly there, and there are some free public bicycles that can be scanned freely on the open space at the end of the road.

Song Wen and Lu Siyu rode a car each, and went downhill all the way. In less than 5 minutes, they arrived at the beach not far from the sea.

There is a large area of ​​reefs on the coast of South Shark Island. When the tide is high, these reefs will be submerged by water. When the tide ebbs, large and small reefs will be exposed. These reefs have been washed by sea water and are very smooth and round.

This place is already close to the seabird habitat by the sea. At this time, there are already a large number of seabirds flying low in the sky. Some are looking for caves on the cliffs where they can hide, and some are holding on to the strong trees. nest.

Animals are much more sensitive to natural disasters than humans. Many times, whether earthquakes or typhoons, animals are the first to discover them.Those birds are naturally sensitive to this coming typhoon.

This place is close to the seaside, and huge swells have already appeared on the sea. The round waves are one or two meters high, and the rhythm is slowly surging over, making a heavy and heavy sound.

The darker the sky, the clearer everything in the distance became.

These are the precursors of the typhoon coming.

At this time, the two girls were standing next to several rocks, which could be seen from a distance.

Qiu Lan saw Song Wen, and then saw Lu Siyu behind him: "Oh, Brother Lu is here?"

Song Wendao: "We just met on the road." Then he looked at Qiu Lan, "Why did you only send it to me?"

Qiu Lanyu hesitated for a while, blinked her big eyes, and explained: "The teacher should have already arrived at the hotel, so I don't want to bother him anymore, and... this matter, we also want to ask someone first, in case we misunderstood Now, isn't that a joke?"

She can't tell, because she thinks Song Wen is more handsome, and also thinks he is bold and reliable, so she wants to ask him to come and have a look alone...

Lu Siyu couldn't listen to their chatting to waste time, so he asked directly: "The typhoon is coming, hurry up, what did you find?"

"Oh, here." Jiang Jiang pointed to them as he spoke. It was a white bone-like thing stuck under two rocks not far away. "We were shooting seabirds at the beach. , At that time, Qiu Lan accidentally tripped on the rock, and we didn't expect that there was a piece of white bone under it."

And the bones... for small animals, the bones are not big enough, and for large animals, the bones are too small.After thinking about it, I think it might be a human bone...

Lu Siyu skillfully put on the gloves, walked over and squatted down to have a look, he first shook the bone-like thing, it was stuck between two reefs, it didn't move at all, he raised his head and said to Song Wen: " lag."

"I'll try." Song Wen said, helping him move the reef next to him, and the two of them worked together to finally take out the thing.

Jiang Jiang and Qiu Lan also became interested at this time, and bowed down to watch. They have studied marine biology, and they also have a little understanding of the bones and anatomy of ordinary animals, so they can make a preliminary judgment. There are bones.

Lu Siyu took that piece of stuff in his hand and observed it carefully. The bone was overall moon-white in color, with bony seams on it, and bone cavities visible at the breaks. It had been eroded by seawater for a period of time, and the flesh and blood on it might have been eroded by the seawater during high tide. The fish gnawed clean.

Qiu Lan boldly asked curiously, "Is this a human bone?"

Lu Siyu didn't answer her, and turned to Song Wen in a low voice, "It's possible."

"Really?" Both girls took a step back.

Song Wen ignored them, he immediately thought of the missing girl, lowered his head and asked Lu Siyu, "Then could it be the remains of the missing girl from before?"

Lu Siyu stretched out his slender fingers to measure and gestured: "This should be the human femur, that is, the thigh bone. It is the longest tubular bone in the human body. According to the length and thickness of the adult femur, the height of the deceased can be inferred. Judging by the thickness and size of this bone, this may be a female femur. However, the specifics need to be tested.”

From mollusks to the appearance of the first exoskeleton organisms, and then to the evolution of the exoskeleton into the endoskeleton, mammals dominate the world.

Bones are often the last things left by animals or human bodies. Meat, skin, and internal organs will decay and deteriorate, but bones can last thousands of years.

Bone is composed of living cells and minerals. It is hard to imagine that such a hard thing is a living and growing tissue that exists in each of us.

Some ancient peoples believe that bones have souls, and they are the blessings of heaven to all things, and they are regarded as holy objects.

Before puberty, there is not much difference between male and female bones. Once adults, due to hormones and growth, male bones will become longer, thick, thick, and rough, while female bones will be short, slender, and slender. The surface is smooth.

Although there are many comprehensive factors that will affect the state of bones, such as region, growth environment, individual differences, hormones, drugs, etc., basic judgments can still be made based on general rules.

Limb bones can determine gender and height.This bone looks like a woman's, and it should be a young, thin and tall woman.

Song Wen asked again: "Can the time of death be confirmed?"

"It has been soaked in sea water, but overall, it is still relatively fresh." Lu Siyu observed for a while while talking, and pointed out a section of the bone to Song Wen, "The surface of this bone seems to be covered with bones. The marks left by sawing should have been sawed after death."

"The wound surface of the scar is flat, not a fracture or a natural formation, but sawn off, and the roughness of the cut surface can reflect the size of the sawtooth."

When Lu Siyu was in university, he once did a project, which was the inspection of saw marks on the cross-section of human bones. The instructor at that time took them to saw several bones with various types of saws, and finally came to the conclusion that different saw teeth The saw marks left are significantly different in microscopic state.

Although there is no better magnifying instrument for him to observe carefully, it is not difficult to judge that it is a bone sawing injury.

In fractures or sawing injuries caused before death, there will be traces of hematoma on the surface of the bone, but there is no such phenomenon in the corpse after death.In the current situation, it is very likely that the corpse has been disposed of.

A lot of clues can be deduced just by relying on a piece of bone, which has not been tested and further microscopic observation.This is the difference between good forensic medicine and ordinary forensic medicine.

Song Wen frowned slightly when he heard this, the missing girl, the bones of the sea, the owner of the cake shop who committed suicide, and the prisoner who has been hiding for more than ten years, this small island seems to have a lot of stories.

Qiu Lan looked at Lu Siyu and said, "You can tell whether it's a man or a woman based on a piece of bone, but you're the one who knows divination, right?"

Lu Siyu looked serious: "This is not mysticism, this is science."

Qiu Lan said: "Of course I know, I was joking, but aren't you a photographer? How do you know so much about corpses and bones?"

Jiang Jiang looked Lu Siyu up and down: "Yes, you are not a forensic doctor, are you?" She was also shocked by those terms.

Lu Siyu shook his head: "I learned it myself from reading books in the past, and it may not be accurate."

Jiang Jiang curled his lips. Just now Lu Siyu used a very firm and professional tone, but now he categorically denies it.

These two boys have been mysterious since they got on the boat. They notified the one named Song Yu, but this one named Lu Siwen came together. All these signs made her feel that the relationship between these two people was It must not be as simple as they say.

Song Wen thought of what the stall owner said earlier. Teacher Su also came to inquire about the missing girl, and asked the two girls: "By the way, have you, Teacher Su, ever married? Have you ever had children?"

Qiu Lan didn't know how to say it to Teacher Su: "It seems that I was married when I was young, but I got divorced later. Since he started teaching us, he has been alone. I don't know if he has had children."

Song Wen asked again: "Has Teacher Su been teaching you all the time?"

Qiu Lan continued to answer: "Yes, Mr. Su is very kind, knowledgeable and very patient. He is a good person who will give money to beggars on the roadside and donate money. He taught us marine biology. In the college, he The number of elective courses is the largest.”

While they were talking, Lu Siyu was still looking down at the bone, while Jiang Jiang looked around and said, "Where did this bone come from? Did it float over with the sea? Could it be picked up by seabirds?" What?" Then she looked at the size of the bone, "But it's so big, it probably exceeds the weight that seabirds can carry."

Song Wen stood up and looked around, "It doesn't look like it was brought by sea water, and it shouldn't be a sea bird..." Then he raised his head and found a cliff not far away, which was right next to the reef. He stretched out his finger and said, "It may be thrown down from that cliff in this direction during high tide. The other parts were washed away by sea water, and this one happened to be stuck in the rock."

If it is high tide, these reefs will not be revealed at all, and they will all be under the sea water.

Jiang Jiang had studied the map of the island before. Hearing this sentence, his face changed slightly: "That place...is not far from the Happiness Hotel and the cake shop." They were going to rush there later.

Qiu Lan tightened her clothes, her braids had been blown a little messy by the wind, and her skirt was not so warm: "Is there no one who died on the island? The girl who disappeared before, was she killed?"

On this small island in a tourist attraction, a suspected human skeleton was suddenly discovered. This incident sounds scary enough.

Song Wendao: "There are some strange things on this island."

In addition to the mysteriously missing girl, the owner of the cake shop on this island committed suicide not long ago.

Before Song Wen could explain in detail, Qiu Lan's face turned pale with fright: "This bone is enough to infiltrate people. There won't be anything unclean here, so... we will..."

Jiang Jiang has always been very rational, but after all, she is a young girl, and at this moment her expression showed a hint of panic: "The most important thing is...the typhoon is coming, and there is no other place to live..."

Seeing how frightened they were, Song Wen couldn't bear to tell the truth, so he didn't tell them about the cake shop owner, and comforted him with a smile: "There are no ghosts in this world."

Lu Siyu stood up, blinked his long eyelashes through the glasses, and said coldly: "In the past dynasties and dynasties on the earth, so many people have died, and so many dead people have been buried in various places. places. The houses you have lived in, the schools you have attended, the roads you have traveled, and even every inch of ground you have stepped on may have bones buried..."

Human history is built on bones.

This is a scientific discourse, and it is telling the truth, but Jiang Jiang and Qiu Lan obviously never thought about it that way.

The sea was rough and the sea breeze was blowing, and the sky was a little gloomy. Lu Siyu was holding a piece of white bone in his hand, wearing gold-rimmed glasses, coupled with his indifferent expression and cold voice, the content of the story was like this again...

The girls were even more frightened, and looked up at him together, trembling. The comforting effect of these words did not seem to be very good.

Seeing the cold scene, Song Wen could only smooth things over for Lu Siyu: "If I could meet a ghost, I would have already. Don't scare yourself."

Lu Siyu looked down at the bone in his hand, wondering whose bone it was and what kind of story it contained.He took out an evidence bag from Song Wen's bag, wrapped the bone in it, and said: "This thing has not been tested, it is not accurate, let's go to the hotel as soon as possible, and then hand it over to the police when we have time." .”

Now, the wind on the beach is getting stronger and the sky is also covered with dark clouds. This typhoon is really coming soon.

Song Wen agreed: "Anyway, everyone, be careful. Go to the hotel first."

Jiang Jiang hurriedly took out his mobile phone to look at it, and let out an ah: "The typhoon is coming soon, let's speed up."

The typhoon that was far away from them just now has moved to the large wind circle on the edge of the island. On the map, it looks like a huge round cake of cream.

In a blink of an eye, the rain was about to fall, and the four of them began to climb up the mountain quickly.Want to get to the hotel before the rain.If you move a little slower, you may be stopped on the road by heavy rain.

Song Wen was carrying two bags, turned around and pulled Lu Siyu, still very relaxed.The two girls fell behind for a while, but fortunately they were young and did not hold back, so they followed closely.

Jiang Jiang thought for a while, then turned to discuss with Qiu Lan beside him in a low voice: "I don't think I should tell the teacher about this bone thing, he can't help much, and I will scare him later."

Qiu Lan nodded, and looked at the two people in front of him.

Jiang Jiang had a premonition that these two seemed more reliable than the teacher. Now that they knew about it, the handsome guy with glasses carefully put away the bones, obediently saying that he was going to hand them over to the teacher. Whatever tests the police do, there should be results.
