Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Chapter 419 New Discovery
Dumping corpses in water is different from dumping corpses in the general sense.

Dumping corpses in water and dumping corpses and burying corpses in the general sense are actually more similar to burying corpses.

For example, Wangjiahe is one of the rivers with the largest water volume in Tianzhou City. The water flow is very poor, and the gap between the upstream and downstream is relatively large. In the past, it was even a canal.

This river has existed in Tianzhou City for who knows how long. It should be said that it has existed since ancient times.

Historically, even in recorded drought years, there has never been a shortage of water flow.

Therefore, if the hydropower station is not constructed and put into operation, the corpses in the river will most likely never see the light of day again.

The murderer dumping the body in the Wangjia River actually achieved the same effect as burying the body.

The vast majority of murder cases basically conform to the law of throwing corpses far away and burying them near. Li Donglin judged that the murderer most likely lives around the Zhongpo corpse basin.

As for why we chose the ten-kilometer range...

This is actually due to experience.

Generally speaking, the place where a person lives for a long time has a familiar range, and this range will not exceed three kilometers under normal circumstances.

In fact, the range of spatial familiarity of normal people is most likely within one kilometer of the place where they live.

Three kilometers is the maximum average range of ordinary people's activities. Li Donglin chose ten kilometers...

This is already the highest limit he has reached in his many years of experience in solving crimes.

If the murderer dumped the body in the water beyond this distance, the possibility is actually very small.

Of course, no one can say clearly that these things must be like this.

There should be no absolute possibility for anything, it can only be said to be a high-probability event, especially in the detection of cases.

Interview surveys are very boring and are also the most likely to cause problems.

Not everyone is a leader, and it cannot be said that they do not have a sense of responsibility, but for most police officers, this is actually a job.

A job to support a family like everyone else.

Lao Bai once told Lu Chuan that people seem to have higher requirements for the police than other industries.

When there is a case, it is necessary to solve it, and when there is an grievance, it is necessary to seek justice. But in fact, the police are also human beings.

Just like doctors can't save everyone, firefighters can't put out all fires.

There will still be cases that the police cannot solve.

The case is very big, but the visit and investigation cannot be rushed. In terms of time, if the other party lives near the river basin where the crime occurred, he must have lived there for at least ten years.

There is a high probability that the other party will not leave just because the police have discovered the body and started visiting and investigating.

Because this may mean that the murderer is more likely to be exposed.

Therefore, the other party will most likely hide and figure out how to spend the interview and investigation normally.

Three days passed quickly.

The visit and investigation... As Li Donglin expected, there was indeed nothing gained.

However, there has been a lot of progress in the cooperation between current investigators and forensic scientists.

In addition to the identity of corpse No. [-], the identities of several other corpses were also quickly confirmed.

The identities of corpses No. [-] and [-] were determined through DNA analysis and comparison with the general population database.

Fortunately, Corpse No. [-] had the shortest time of death, the flesh and blood did not completely decay, and the body did not liquefy to a large extent. The DNA identification was very simple and was completed in less than a day.

However, corpse No. 15 died between ten and fifteen years ago, and the flesh and blood in the box had long since disappeared. If the box containing the body had not been made of genuine leather, it would have been corroded by the water.

Sun Jian, Wang Changjiang and others worked hard in this area, carefully processed the bone marrow, and tested it three times before finally successfully identifying the DNA information.

Of the five corpses, the identities of three were identified the next day, and after another two days, the identities of the five corpses were finally identified.

Ten people work shifts at the forensic department, with basically no rest.

"Old Sun, I can't stand it anymore, I have to take a nap today." Wang Changjiang's eyes were as dark as those of a giant panda.

As I get older, no matter what I do at night, it’s actually not very good.

Even small pills only treat the symptoms but not the root cause, just like Wang Changjiang's urination splitting. Occasionally, he can't separate his urine after drinking too much water. You can't hold it in every time you urinate.

"Okay, I'll report to Director Li."

Sun Jian is no better than Wang Changjiang.

The case originally occurred in Tianzhou City. Logically speaking, even if it is now taken over by the Provincial Major Crime Team and ten forensic doctors are dispatched, there is no reason for anyone to really fight for it.

They are all old fritters, and to endure it to this extent is really just for the sake of their friends.

Lu Chuan hasn't had a good rest these days.

When the forensic doctors were boiling the big bones, he was responsible for analyzing the big bones.

Sun Jian's reason is also very good. The corpse without flesh and blood is the scope of the skeleton.

No one here is better at identifying and analyzing bones than Lu Chuan.

The identities of the other two corpses were determined by Lu Chuan's skeletal analysis.

Corpse No. [-] still had signs of fracture in the hip bone, and a steel plate was placed inside.

Placing a steel plate in the hip bone is not something that ordinary hospitals can do.

A group of people were photographed going to the Orthopedics Department of the No. 1 Civil Hospital in Tianzhou City. After just asking, they determined the identity of the other person.

After all, the business of implanting hip plates is also very good in the hospital.

Corpse No. [-] is more distinctive. It is a bone cancer patient, and it is in an advanced stage.

In other words, even if Corpse No. [-] was not killed, he probably wouldn't have survived for long.

Two groups of people were sent to check the hospital in Tianzhou City for a day before locking in the identity of the other party.

To determine the identities of the five people, according to the general thinking of handling the case, it is necessary to conduct a cross-analysis of the personal relationships of the five people.

It's like doing a math problem, finding the intersection of five sets.

If the murder was not random, is it possible that some of these people knew each other?

If so, the case may be solved by finding a common acquaintance of the victim.

Of course, this is only the ideal state.

Facts have proved that Li Donglin thought too much. These five people...

So far, no life intersection has been found.

"Five people, one in Beishan Town, two in Nanling, two in Tianzhou City, and one in Julu County."

Wang Song is responsible for the background checks of several people.

"The identity of corpse No. [-] was that of a masseuse, and the transaction was in cash, so it is difficult to identify the suspect by tracing the financial channels."

"Corpse No. [-] is a self-employed person selling rice."

"Corpse No. [-] is the taxi driver."

"Corpse No. [-] was a bicycle repairman during his lifetime."

"Corpse No. [-]... is the owner of a bun shop."

"These five people basically have no close interactions in life."

The reason why Wang Song said they are close is because these people are doing business for ordinary people, and they may have had business relationships with each other.
