Detective: Open your eyes, I am handcuffed in the interrogation room.

Chapter 569 Start investigation

Doubts may be doubts, but it does not mean that there is really something wrong with these two people. The most important thing at the moment is to confirm the identity of the bones as much as possible.

Only once the identity is confirmed can the case be followed up.

This matter is somewhat difficult.

The thought flashed through his mind, and Chen Yi did not deliberately target Luo Bao. He asked about the museum project step by step, especially the workers who were able to place the bones on the gate.

Everyone said that they had not seen any colleagues acting suspiciously, nor had they seen any skeleton-like objects in advance.

The bones would naturally not appear out of thin air. Chen Yi checked the mechanism that caused the bones to fall and their location again, and finally determined that the bones should have been placed here at night when no one was around.

It is too dangerous during the day and it is very easy to be discovered.

Although the mechanism is simple, it is ingenious. The location of the bones is hidden and cannot be seen by people passing by. Just place the bones here in advance, open the mechanism trigger conditions when needed, and apply downward pressure to make the bones fall down, just facing the person who stepped on the mechanism.

It doesn’t matter who stepped on the mechanism. Sun Yuanfa was just unlucky and got scared.

Chen Yi instructed He Shixin to investigate the surveillance. There was no surveillance in the museum but there were other places. Maybe they could capture the people transporting the bones.

In addition, the technical investigation team needs to carefully check the bones and every part of the mechanism to look for fingerprints.

If the fingerprint can be extracted, things will be simple.

Chen Yi had a hunch that it would be easy to find the person who placed the bones in a short period of time. He could ask about the motive, the identity of the bones, how they died, and what the relationship between them was.

But if it cannot be found, the investigation of this case will be extremely complicated.

The difficulty is completely different.

So, every effort must be made to try to find the person who placed the bones.

Everyone present must be questioned.

The call from the provincial department came faster than expected. It seemed that Sun Yuanfa had already reported the matter to the provincial government.

It wasn't Wei Jianfeng who called, but Fang Songping.

Director Sun from the provincial government saw white bones on the lake island of Yangcheng's key project. The nature of this incident has exceeded that of an ordinary criminal case, and pressure from all parties will be concentrated on the provincial department.

The provincial department will continue to put pressure on the criminal investigation detachment of the municipal bureau, and even if Fang Songping is the father-in-law, he cannot escape.

"The sooner the better. We must not delay. Many people know about this matter."

After explaining the situation, Fang Songping asked Chen Yi to focus on investigating the Lake Heart Island Bones Case, to allocate as many police officers as needed, and to put all other cases on hold.

"understood."

Chen Yi hung up the phone.

In fact, the supervision from above meant little to him. He had never been lazy when investigating a case. He would solve any case that could be solved. If he couldn't solve it, it would be useless even if Di Cheng put pressure on him.

At all times, criminal police must remain calm.

Sun Yuanfa hadn't left yet. After finishing the call, he stood there watching, waiting for Chen Yi to finish his work.

Chen Yi came to Fang Shuyu and asked, "What's going on?"

Fang Shuyu took off her mask, stood up and said, "Nothing else was found. It's too clean. I'll check it carefully again when we get back to the Municipal Bureau."

"Clean?" Chen Yi lowered his head and glanced at the bones. "What do you mean?"

Fang Shuyu: "It literally means clean, without any dirt or stains. The whole body has been carefully cleaned, without even a speck of flesh or blood."

Chen Yi said, "What's your age?"

Fang Shuyu: "Judging from the degree of tooth wear, he is probably around 30 years old."

Chen Yi: "How long will it take to reveal the time of death?"

Fang Shuyu thought for a moment and said, "Neither soil nor microbial activity can be used. High-precision instruments from the provincial government may be needed. I will give you a rough range tomorrow."

In forensic science, determining the time of death of a skeletonized body is a complex process.

Since skeletonization is the final stage of corpse decay, the corpse has undergone a long period of decomposition and traditional corpse phenomena such as livor mortis and rigor mortis no longer exist. Therefore, other methods are needed to infer the time of death.

If you are in the wild, you can use methods such as entomology, geology, and soil science, such as judging by the moisture, pH, and number and developmental stage of the soil.

None of these apply in the current situation.

High technology is required.

Radioisotope detection method, molecular biology method, etc. are all acceptable.

Chen Yi nodded, squatted down and looked at the female corpse in front of him.

There is a high probability that he was killed, but why he appeared here is something I cannot figure out for the time being.

After looking for a while, he called Zhuo Yun and asked him to investigate the missing persons reports in recent years to see if there were any that matched.

DNA paternity testing is the most convenient method.

The disappearance of a young woman should not have gone unnoticed. If that were the case, the investigation of this case would have been much more difficult, and the skull restoration would have been necessary to find a needle in a haystack.

Chen Yi left the scene, but the investigation is still going on.

He found Sun Yuanfa and they started chatting.

Sun Yuanfa has completely recovered and looks calm, without any signs of lingering fear, as if nothing had happened just now.

Sun Yuanfa was not surprised to learn that this case would be classified as a major criminal case. Which bastard would go to so much trouble to do such a thing on the island in the middle of the lake? It certainly wasn't for a prank.

"This is a naked provocation." Sun Yuanfa's voice was cold. "After killing someone, they didn't think of a way to deal with the body, but instead exposed it in broad daylight. Only a madman would do such a thing!"

He didn't know whether the person was killed or not. After Chen Yi mentioned the major criminal case, he naturally thought it was a homicide.

Since it is a murder case, the person was naturally killed.

Chen Yi said nothing else, "The Criminal Investigation Brigade will do its best to investigate, Director Sun, don't worry."

He did not say anything good to Jiang Fanlei. Investigating the case was the most important thing at the moment, especially since a solution had already been found.

Jiang Fanlei should discuss the criminal investigation exhibition hall with Sun Yuanfa, and the latter will definitely agree, but there is a prerequisite, that is, the sudden appearance of bones on the island in the middle of the lake must have a result.

Since it was not aimed at him, Sun Yuanfa left after understanding the situation. Before that, his secretary and entourage were questioned and left their identity information.

Sun Yuanfa didn't care and cooperated fully. He even took the initiative to provide his recent itinerary and said that the last time he came to the island was half a year ago.

This saved Chen Yi a lot of effort, after all, everyone present was a suspect.

As the visit and questioning progressed, a feeling of uneasiness gradually grew among the crowd. Before a commotion could break out, Chen Yi gave the order to let them go.

As long as you have been questioned and left your identity information, you can leave the island at any time under police supervision.

Seeing this, everyone felt relieved. Many people left the island, while a small number of people who had a good relationship with Jiang Fanlei chose to stay and see what happened next.

The bones had been taken away, and the technical investigators returned to the Municipal Bureau after completing the investigation.

The harvest was small, no fingerprints or suspicious substances were found. The suspect must have taken protective measures when placing the bones and the mechanism.

Luo Bao and Zuoqiu Anqing are still here.

During this time, Chen Yi had not given up observing the two people, but it was too late. When the bones first appeared, he had no idea how the two people would react. Instantaneous reactions were the most real, and even if there were any problems now, they would have been completely hidden.

After the incident, Zuoqiu Anqing stayed with Jiang Fanlei all the time, so she did not meet Luo Bao. They just greeted each other as friends when they looked at each other from a distance.

Chen Yi found nothing suspicious and made no judgment for the time being.

There were fewer and fewer people on the island. Jiang Fanlei found Chen Yi at this time to ask about the engineering problems and whether the work should be stopped.

"Do you still want to start construction?" Chen Yi asked back.

Jiang Fanlei said helplessly: "Okay, let's just stop. How long will it take to find out? We were originally planning to open next year."

Chen Yi's answer was relatively conservative, and he did not give Jiang Fanlei any hope: "Make plans for half a year."

"Half a year?!" Jiang Fanlei almost vomited blood, but there was nothing he could do since it was because of such a thing that happened on the island in the middle of the lake.

It would be fine if only a few people knew about it, but the skeleton almost kissed Sun Yuanfa, and there were so many people watching, it was impossible to hide it.

The police's warning can only ensure that the incident will not become known to the whole country.

It will still spread within a small range.

For a long time in the future, the island in the middle of the lake will become a forbidden area in Yangcheng, until the truth comes out and a notice is issued, and a criminal investigation exhibition hall is opened as a matter of course.

"Don't worry about this matter." Chen Yi said, "You should find a way to appease the shareholders and senior management. Don't let me finish my investigation while you disappear."

Jiang Fanlei took it seriously: "Yes, you are right, I have to go to the meeting quickly."

Chen Yi glanced at Zuo Qiu Anqing who was beside the other person, then turned and left.

……

After returning to the Municipal Bureau, Zhang Jingang also received a call from the Provincial Department, asking him to participate in the supervision of the Lake Heart Island Bones Case during this period. After Chen Yi led the team back, he immediately convened a meeting.

Except for technical investigators and forensic doctors, almost everyone in the detachment participated.

At this time, He Shixin had just finished reporting on the surveillance investigation. Because no one knew when the bones were placed there and there was no accurate timeline, it was difficult to investigate and it would take time.

At least last night, there were no findings.

Of course, the surveillance coverage area of ​​the lake island is not very large, and the suspect may have avoided surveillance last night.

This is a very difficult situation. We can only adhere to the principle of not letting go of any possible clues and try to continue investigating.

After learning all the circumstances, Zhang Jingang looked at Chen Yi and asked, "What do you mean?"

For Chen Yi today, he doesn't need to ask too much, just three words will be enough.

Although he was said to be participating in the supervision, it was just a symbolic participation. Now Chen Yi's level was the same as his, and no one ordered anyone around.

Even he might not have thought that the young man he met in the interview a few years ago would reach his current position so quickly.

Chen Yi looked away from the big screen and said, "There must be some insider trickery. The person who placed the bone mechanism must be at the scene today. However, from the questioning, the other party did not reveal any flaws. His psychological quality is still good enough."

Zhang Jingang: "This must have been planned for a long time. Since they intended to let the bones be discovered, they were naturally prepared to deal with the police. Do you think the murderer and the person who placed the bones are the same person?"

Chen Yi: "Obviously, if it's the same person, the behavior wouldn't make sense, but..."

He paused and continued, "But the body has turned into bones. A lot of time must have passed. Maybe something special happened during this period, causing the murderer to behave illogically."

Zhang Jingang is an old criminal policeman, and analyzing cases is also his strong point. At this moment, he said: "If it is not the same person, then the person who placed the bones was just to let the police find the murderer.

Right now, this is the most likely possibility, right? "

Chen Yi nodded: "This is indeed the biggest possibility, so why didn't he (she) call the police?"

Zhang Jingang: "What do you think?"

Chen Yi: “Two inferences. First, this person himself is suspected of committing a crime and dares not deal with the police.

Second, this person has other things to do, and this matter is very secretive, so his identity cannot be revealed for the time being. "

Zhang Jingang frowned: "Then this case is complicated. No matter what, confirming the identity of the bones is the top priority. Only when the identity is confirmed can we find out the doubts."

He had a very thorough understanding and realized that it was almost impossible to accurately find the place where the bones were placed among the crowd that appeared on the island in the middle of the lake today.

Of course, we still have to investigate, maybe we can find other clues, such as the identity of the skeleton.

There is no need to mention this matter, Chen Yi must know about it.

The person who placed the bones must know the owner of the bones. If they know each other, it is possible for the police to find out during the investigation.

For example, if a worker’s friends or relatives cannot be found and their age and gender meet the requirements, they can be listed as key investigation subjects.

The tasks were quickly distributed. First, the workers responsible for building the Lake Heart Island Museum were investigated, then all the workers on Lake Heart Island, thirdly the other employees on Lake Heart Island, and finally the guests invited today.

The investigation required a large number of police forces, so Chen Yi and Zhang Jingang were immediately transferred from the branch bureau and police stations, and a death order was issued to severely punish those who were negligent.

Late at night, Chen Yi came to the forensic room.

The medical examiner is working overtime.

The identity of the bones is the key point, but the bones themselves are also of paramount importance.

He was not here to supervise the work, he just wanted to wait for the results, just because Fang Shuyu was his wife, they would go home together after they were done.

Without making any noise to interrupt, Chen Yi casually flipped through the autopsy notes on the table. The contents of the notes would become part of the autopsy report in the future.

The wound on the back of Baikui's head was irregular. Based on experience, it should have been caused by something similar to stone.

He is 1.70 meters tall.

A very tall woman.

"Attack from behind."

Chen Yi looked at it for a while but didn't see any useful information, so he put it back.

"If he attacked from behind, does he know him or not? It's hard to say."

The analysis of clues needs to be combined with the scene to restore the circumstances of the crime, but there is no scene at all in this case. There are too many possibilities, and it is useless to waste your brain on it.

Cases from a long time ago would give any veteran detective a headache.

After waiting for half an hour, Fang Shuyu came over and said the same thing as she did during the day: "It's so clean."

Chen Yi: "Did you clean it up very carefully?"

Fang Shuyu: "Yes, there is no impurity at all. I will go to the provincial department tomorrow, so I will go home first."

Chen Yi nodded, thoughtfully.

Regardless of whether the murderer was the one who placed the bones, if the one who placed the bones cleaned them, why? Why did they clean them?

Is it obsessive-compulsive disorder, perversion, or special feelings for the owner of the bones?

Without an identity, there will be no answers.
