An Analysis of the Answer to The Dutch Apartment Murder;

case analysis

20 13 lei helped the police to solve many cases, which caused quite a stir in the police station.

In an encirclement and suppression of a small gang, Lei provided and analyzed key evidence. As a result, the police arrested the people involved, and Lei was also involved.

The early arrest went well, but the two brothers in the gang, Bos and Pete, slipped into the alternate hidden route. Ray found that two men had escaped, so he ran after them and shot Peter in the leg without authorization. Pete, who lost his mobility, turned around and shot ray to cover his brother Bos's escape and successfully hit ray. Bos managed to escape under the cover of his brother Pete. Peter was caught by the reinforced police.

That's how ray's leg injury was attributed to Pete. Although Peter was arrested, Ray's license was revoked by his superiors because of his reckless impulse. Although ray is dissatisfied, he is still bent on finding Bos who is at large. After his recovery, Ray began to investigate Bos, during which Ray discovered that Bos had a history of drug abuse. In order to continue the investigation, Ray decided to find and follow the boss.

Ray spent two years locating boss.

The leg injury made Ray lose the target again and again, and also made Ray almost seen by Boss. These pains and dangers deepened Ray's hatred for Bos.

2065438+05101On October 22nd, Ray found Bos wearing a hood and stealing from a convenience store while the shopkeeper was dozing off at the counter. Ray wanted to remind the shopkeeper, so he called the landline number on the signboard outside the store. The landline was set in the shop, and the bell woke up the owner Albert.

Albert saw Bos stealing, so he quickly reached for the baseball bat under the table. Bos, who was addicted to drugs, misunderstood that Albert's action was to pull out his gun, so he pulled out his gun and shot Albert.

This process was clearly photographed by the monitoring in the store.

Albert fell in a pool of blood, and so did the thunder from the telephone booth outside the store. Ray would never have thought that Bos actually shot and killed people directly within his sight. Lei went into the store to check the situation and tried to catch up with the escaped Bos, but his leg injury prevented him from running 50 meters.

This process was also clearly photographed by the monitoring of the owner next door outside the store.

Ray felt desperate and regretful. He was sent to the hospital again because of the recurrence of his leg injury. At this time, Ray vowed to let Bos's blood come out.

The case is not closed. Albert's body was just dragged away by the patrol. Winter, the only son of owner Albert, has just gone to military service. Winter received this letter and learned that his father died three days after the incident. When Logan, the owner next door, told Winter about his death, he also mentioned that the key clues he reported were ignored by the police. Winter thought for a long time, and he decided to retire early and come back for revenge. However, Winter didn't have a suitable reason to retire, so his retirement procedures were delayed by his superiors.

Time has reached 20 16, and Lei still hasn't given up his pursuit of Bos.

On the afternoon of July 8th, around 16, Bos and Eric agreed to meet in an alley for the purpose of dealing drugs. Ray followed Bos to this place and photographed the hard evidence that Bos and Eric were dealing drugs on the roof beside the driveway.

But before that, the police targeted Eric's backstage drug trafficking group and followed Eric to the street.

The police sounded sirens from all directions.

Bos and Eric in the dark alley quickly threw all the drugs into the sewer to sell stolen goods.

Afterwards, due to the incompetence of the police at that time, Bos and Eric were sentenced to heavy sentences for selling hard drugs. In the end, the two were sentenced to prison for illegally possessing guns.

Eric has been a big drug gang for many years, and he went to the same prison with Bos through connections. Boss's brother Pete is also in this prison. The three of them soon negotiated. Starting with the damn detective and convenience store owner, we talked about how Eric and the boss were so busy pouring drugs into the sewer that they forgot that they had guns to resist. Peter said that he was sentenced to life imprisonment for shooting and assaulting a police officer, and his only wish was that his brother Bos could retaliate against Ray after he was released from prison.

The boss agreed.

Time passes slowly. Ray has been living a poor and depraved life these days. He is waiting for Bos to break up with him after he gets out of prison.

Ray rented a house in Dan's apartment building. Dan's long-term rent is extremely cheap. Because there was a dismemberment case here a long time ago, there is almost no long-term rent. As a witness to the dismemberment case at that time, Dan witnessed the cruel truth from the garbage bag and was mentally ill.

Since then, Dan has been particularly worried about the tenant's garbage bag. He always checks the tenant's garbage himself until he makes sure there are no bodies in it. In order to prevent the apartment where the murder happened from being rented out, Dan removed all the apartment house numbers to cover up the number plate at the scene of the murder, so that the tenants who don't know the truth can continue to rent the apartment.

Ray doesn't know or care.

In April of 20021year, Bos and Eric were released from prison one after another. Ray got through to the captain and got the address where Eric was arranged after he got out of prison. Ray left a letter in front of Eric's address with a photo copy of Bos's drug deal with Eric and his telephone contact information.

A copy of this photo is enough to convict Eric again.

When Eric saw the photo, he immediately dialed the phone number left by Lei in the letter. On the phone, Ray hoped Eric could get close to Bos and kill him, otherwise he would give the photos to the police and put him in jail again. Eric promised ray verbally, but he had other ideas about it.

In Eric's view, the person who may have taken photos and used himself to kill Boss should be the relative of Albert, the manager at that time. So Eric found Logan, the owner next door, on April 3, 20021year, inquired about the interpersonal relationship of Albert, the manager, and then contacted Winter, a soldier who later retired.

Winter is obviously not the person who contacted Eric. He doesn't know Eric exists. Eric won the trust of Winter and Logan by telling the details of the death call.

Logan then showed Eric the most crucial evidence of the case that year. Although the people on the monitor were blurred, Eric recognized Bos as the runaway in the picture at a glance. There is also ray who wants to catch up with Bos in the video, but the picture is also blurred. Although Eric knew the identity and whereabouts of the murderer Bos, he didn't disclose it to Winter, but only revealed the situation of Ray to Winter, and hinted that Ray was probably after Bos.

On April 2002 14/KLOC-0, Dan got pictures and information through the phone card that Lei threw in the garbage bag.

Dan has been relying on drugs to maintain his spirit. He wants to make some money from this drug dealer by selling information such as Ray's address. Dan contacted Eric and inadvertently revealed Ray's identity. The two sides then reached a deal, mdash, in exchange for drugs and money with Ray's address and personal information.

After the transaction was completed, Ray's address was exposed to Eric.

Because Ray has a copy of the photo, Eric decided to destroy the original photo and other materials and evidence, and then put an end to everyone's long-cherished wish.

Eric moved into the second apartment opposite Ray under a false identity, waiting for an opportunity to observe Ray's life and learn about his habits. His room is a mess, and the door mirror of the security door is cleaned inside and outside. It is speculated that he often observes through the door mirror.

Winter asked Eric about Ray many times, and there were signs of doubt about him. Eric revealed Ray's address to Winter. Hearing the news, Winter said that he wanted to meet with Ray to learn about the progress of his father's death. Eric also told boss ray's address. After several days of observation, Eric discovered the law of Ray's life and thought it was an opportunity. Boss wants to kill someone. He can destroy the evidence in Ray's hand.

2021on the morning of April 23rd 10, Lei went out and was shot unconscious by Eric who had been waiting for the elevator for a long time. Eric dragged Ray to his rented room 2, so the door of the room was clean and there was dust on Ray's clothes and the back of his head. Then he found the key to room 1 on Ray, opened Ray's door and began to destroy the evidence.

10: 09, Winter enters the building and comes to the front of the apartment. Eric is still in the room at this time. Winter knocked on the door of apartment 1, and Eric in the room was worried about exposure and didn't respond to Winter. Winter mistakenly thought that Ray was not at home, so he called Ray. The telephone rang from Nellie's pocket in the second apartment.

Winter was standing outside the apartment. When he heard the bell, he was confused and thought he had knocked on the wrong door. So Winter turned to knock on the door of apartment 2, but no one answered.

As there is no house number, Winter intends to inquire about the property. Winter learned from the corridor advertisement that the landlord Dan usually lives on the top floor, so he went upstairs to find the landlord Dan through the elevator to understand the situation of the resident Lei. Winter enters the elevator and presses the button of 10 floor.

At this point, Eric finished processing the evidence, left the key on the table, went back to his apartment 2, and moved Ray back to apartment 1. Eric didn't close the door of apartment one, but left a crack in the door, waiting for the boss to arrive.

Then Eric went straight back to his apartment.

10: 25, Bos came to the door of the thunder. At this point, ray was half awake, and he looked at Boss in confusion. Boss immediately strangled Ray from behind with a thick nylon rope he carried with him.

It's too late for ray to react. After struggling for a long time, my right hand pulled out a self-defense dagger hidden in my waist and stabbed Bos behind me. Although Bos was injured, he didn't let go. After Ray lost consciousness, he still didn't stop strangling until Ray died. After listening to Winter's statement, the landlord decided to take the spare key and go downstairs with Winter to check the situation of the resident Lei.

At this time, in the apartment, after confirming the death of Ray, Bos grabbed the injured part and escaped from the apartment. As the dagger was still inserted in Bos's wound, only a small amount of blood was dropped in the corridor.

Because he was afraid that the crime scene would be discovered too early and he could not get away smoothly, Bos closed Ray's door before leaving. Bos walked to the elevator and ran into Dan and Winter at the corner of the corridor. Bos, whose clothes were covered with blood, made Dan excited. Winter, on the other hand, thinks that one of the two households on the fifth floor is Lei, inferring that this person's injury is probably related to Lei, and judging from his keen insight into joining the army that Bos is the murderer who shot his father and escaped under surveillance.

Bos lied that someone was going to kill himself, and the murderer was knocked unconscious by him and asked for help. Winter told Dan to stay where he was to prevent the murderer from escaping. He made an excuse to escort the injured to the first floor. In a panic, Dan listened to Winter's advice and resisted the door at the entrance of the apartment.

Winter helped Bos open the elevator door. Bos collapsed against the elevator wall because of excessive blood loss. Winter has no intention of helping Bos, the patricide. He took advantage of Bos' inattention, pulled out the dagger left in Bos' body and let Bos bleed to death in the elevator. After the death of Boss, Winter called the emergency number and left the building to wait for rescue clues, hoping to help the case come as soon as possible.

At this time, Eric in apartment 2 saw Dan leaning against the door of apartment 1 through the door mirror. So Eric deliberately opened the door and reprimanded Dan for spying on the tenant. Dan turned to defend himself and explained the situation to Eric. Eric suggested that we go into the house to subdue the murderer and then call the police.

So Dan used the spare key to open the door of apartment one. Dan and Eric enter the apartment and see Ray's unsatisfied body. Dan didn't notice. Eric behind him pulled out a stun gun.

Eric stuns Dan from behind with a stun gun, takes Dan's spare key chain, locks the door outside the apartment with the spare key, and then runs to Dan's home on the top floor with the stun gun and spare key to find the photos and phone cards that Dan uses to trade with himself. After finding the evidence and destroying it, Eric tried to leave by elevator. When the elevator door opened, Bos collapsed in the elevator. Eric had a brainwave, took his fingerprints off the landlord's spare key chain, hid them in the boss's pocket, and left the building by the stairs as quickly as possible. He didn't notice that the sleeping Dan always had a copy of a photo that was enough to convict Hailip;

Analysis of blood in the corridor.

The direction of the end of the blood trail is the direction of the injured person's movement. Therefore, the injured person in this case moved from west to east in the corridor.

How did Ray die? Why is the electric injury the same as Dan? Is it possible that the ligature marks were artificially forged after Ray's death? Could it be that Bos didn't kill anyone at that time, and Eric made up the knife later?

(1) Ray was shot by Eric with electric shock before he died, and then he woke up and was strangled from behind by Bos with a rope. Ray was able to move when he was attacked because of scratches on his neck. However, after the dagger was inserted, it was not pulled out many times to resist, indicating that Lei had exhausted all his strength and his ability to act was weak. Bos is injured at this time and will not give him a chance to come back to life and hurt himself. After Bos escaped, Ray didn't chase him or call the police, which shows that Ray is at least in a coma, but there are clues in the autopsy that there is only a circle of ligature marks on Ray's neck, and there is no secondary ligature mark.

(2) The electric injury at the back of the neck was not the cause of death of Ray, which was the same as that of Dan, because both of them were attacked by Eric.

③ In order to distinguish the sulcus before and after birth, besides the sulcus bleeding before birth, the skin of sulcus can be examined histologically and histochemically, and the contents of histamine and 5- hydroxytryptamine can be determined biochemically. The content of sulcus increased obviously before death, but did not increase after death.

What Bos wants is to avenge his gangster brother, and he will definitely want to pay for it. Besides, if Eric wants to be killed by lightning, he can do it when using a stun gun. If Eric killed Ray because he had evidence, then Dan knew about it and should kill them both at the same time. When Eric escaped, he thought that the evidence had been destroyed, and killing Ray was not good for him. See case restoration for details.

Does Dustin I have anything to do with this case?

The best way to analyze this connection is to find out the similarities between the two cases. After our analysis, it is found that the biggest connection between the dusty case and this case may be the landlord Dan.

Before that, let's pay attention to the apartment itself, which is currently in the charge of the landlord Dan. According to the people, the apartment is very good in all aspects, but the rent is extremely low, which is obviously unrealistic. According to Dan's clues, it can be found that his father was sent to a nursing home on 20 15, 1 1 because of the deterioration of schizophrenia, and the date of dismemberment was also that month. Dan's father's admission to the hospital undoubtedly caused financial pressure on Dan. Moreover, we know that if a bad murder happens in a residential area or house, its credibility and reputation in the surrounding areas will be reduced, and guests will be reluctant to rent it over time. Because of the murder case, the room on the fifth floor of the apartment has been unoccupied for a long time, which made Dan bear the economic loss.

(1) so in order to eliminate the influence of the murder 50 1 room, Dan simply removed the house number. As a result, it is difficult for tenants to tell the truth of rumors.

At the same time, the influence of the murder case made the landlord Dan insane, thus forming tinea disease that likes to check other people's garbage bags, and also brought bad schizophrenia to the landlord Dan.

Compared with dust case 2, dust case 1 provides few clues. Therefore, the main direction of joint investigation should be the second dust case with rich clues.

Popular science time:

First, since 1976, the Dutch government has divided drugs into hard drugs and soft drugs. Severely crack down on heroin, cocaine and other hard drugs that seriously endanger public health. And I like ldquo marijuana rdquo, a so-called ldquo soft drug, which is allowed to be traded publicly. Of course, the Dutch move is not to encourage or support the legalization of drugs. Its main purpose is to isolate marijuana from illegal channels, thus reducing people's access to hard drugs. It is worth noting that the hard drug addiction rate in the Netherlands is currently 3/5 of the EU average; The rate of HIV infection through intravenous injection is 10%, which is lower than the EU average of 40%.

Second, genetic factors play an important role in the pathogenesis of schizophrenia. The research shows that the risk rate of comorbidity of first-degree relatives is about 4%- 14%, which is about 10 times that of the general population. If both parents suffer from schizophrenia, the risk rate can be as high as 40%. Among the second-degree relatives of patients, the risk rate of illness is about 3 times higher than that of the general population. Foreign studies show that the comorbidity rate of schizophrenic single-egg plums is higher than that of double-egg plums. The comorbidity rate of single egg plums is 6%-73%; The comorbidity rate of twins was 2. 1%- 12.3%. Studies show that schizophrenia has certain genetic factors, and the closer the blood relationship, the higher the risk rate; Genetic factors are more influential than environment and other factors. So far, the research on gene mapping of schizophrenia is inconclusive. Schizophrenia may be polygenic inheritance, which is caused by the superposition of several genes.
