The saddest thing in the world is that the white-haired people send the black-haired people, and when their children are suddenly destroyed, "unnatural death", many parents' hearts are like a knife, many times, when these parents learn that their children are dead, their hearts will die together, supporting their physical motivation to live, there is only revenge, and this kind of revenge anger will burn for a long time.
The famous Chinese detective Li Changyu once took the initiative to take over a case, and when he briefly learned about the situation of the case, he made up his mind that he must bring the real culprit behind the scenes to justice.
On the afternoon of July 16, 1973, in the Temple Street parking lot in New Haven, Connecticut, in the northeast of the United States, the cleaners cleaned the entire parking lot as usual, and when a cleaner cleaned up to the tenth floor of the parking lot, he suddenly found some blood flowing down the stairs of the 10th floor.
Seeing this bloody scene, the cleaners present screamed in fright, then turned their heads and ran, and then called the police.
When the police arrived, they were also startled by the scene in front of them, and immediately sealed off the entire parking lot, and the forensic doctor who followed also began the autopsy.
The young girl had b-blood, and the direct cause of death was that she had been stabbed twice in the chest, lost too much blood, and according to the blood stains, this was not the scene of the first crime.
The police then searched the entire parking lot and found a Buick car on the ninth floor, which was covered in blood, and after identification, this should be the scene of the first crime.
The girl must have been stabbed in the chest in the car, then struggled to escape, ran out of the Buick car, and then panicked, in the process of escaping to the roof, because of excessive bleeding, physical weakness, fell on the stairs and died.
There was a blood-stained tissue box, a wallet, and a parking ticket in the car, and according to the information related to the identity inside the wallet, the police determined that the girl's name was Penny, 21 years old, and the blue Buick car was Penny's.
After the police continued to search, a blood-stained handkerchief was found on the stairs on the 7th floor of the parking lot, after preliminary identification, the blood on this handkerchief was o-blood, not Jenny's B-type blood, but this handkerchief is likely to be left by the murderer, because the blood extracted in this Buick car, in addition to Jenny's B-type blood, also contains a lot of O-blood, it is likely that in the process of Penny's struggle, it also injured the murderer, and later after the police extracted the testimony of the relevant witnesses around, This is all the more evidenced by this.
According to the testimony of many witnesses, the police initially restored the course of events, the murderer was chasing Jenny up to the tenth floor, but at this time the murderer may have been injured, because someone saw that his left hand was wrapped up, the two chased up to the 10th floor of the parking lot, after half an hour the murderer drove away, because the parking lot toll collector had been in contact with the murderer, he reflected that the murderer was wearing a mask, covering himself very tightly, he could not see his face clearly, but the parking ticket that came over was stained with blood. I also had a brief conversation with the toll collector at the station.
Station toll collector: "Do you need help?" ”
Murderer: "No, hurry up." ”
But when the police wanted to know more, the witnesses could no longer say anything, and they only saw it.
This kind of testimony can only allow the police to draw a rough "portrait" of the murderer: a white man in his twenties and thirties, with a thin body, a wounded left hand, and a Western European accent.
this... Saying it is the same as not saying it.
Because of such a person, the entire city of New Haven can at least find out a hundred and eighty thousand for the police, where to determine the specific identity of the murderer.
The reluctant policeman returned to the scene again, carefully studied several "evidences" left at the scene, and finally made some discoveries.
On the blood-stained tissue box, the police extracted a fingerprint, and in the few blood stains left by the murderer, the police found the composition of the car oil, most likely the murderer was an auto mechanic, or a person engaged in related work.
The next clue is gone.
At that time, the technical means were not as advanced as today, there was no help of "big data", even if the police held fingerprints, they did not know who to compare, as for the auto mechanic, or that sentence, the entire city of New Haven could at least find out a million and eighteen thousand, these two clues, but also from the "needle in the haystack", reduced to "the big lake needle", the difficulty, or difficult.
In this case, the police decided to change their thinking and start with the murderer's motives for the killing.
The police first identified the suspect as Penny's ex-boyfriend, Delito.
Delito and Penny had already reached the point of talking about marriage, but the two of them cancelled the wedding out of a quarrel, in which case Delito was likely to hold a grudge and kill Penny, and he was indeed a thin, 24-year-old white man.
The police then took Delito to the police station for interrogation, but Delito immediately produced evidence in order to get rid of the suspicion.
At the time of the crime, he was eating in a restaurant, and the people at the same table and the waiter in the restaurant could prove this, and his left hand was not injured, and he was not o-blood.
Under these "evidences", Delito was quickly cleared of suspicion and released from the police station, but this time the problem was even more difficult, because as the police continued to investigate deeply, it was found that Penny's interpersonal relationship was very simple, and he had never had a vendetta with anyone at all, nor had he had a financial dispute with anyone.
Vendetta killing, financial killing, and love killing are impossible, then this case is really going to become a "headless public case". As we all know, what case is the most difficult to crack, that is, the headless public case, a criminal murderer randomly "casts" a city, and then casually "casts" a small township in this city, and then directly stabs a person to death in the past.
As long as there is no surveillance, no witnesses, and no traces left by the murderer at the scene, then this kind of case is basically impossible to solve.
This is the case in this case, the police investigation has been in a stalemate for a while, who knows this stalemate, it has been frozen for more than ten years, and a few blocks near the crime site have always been panicked.
There may be a murderer around me, but I don't know who this murderer is, whether he will commit a crime again, and who in these neighborhoods is not afraid.
And Jenny's father Jon originally had a factory, life is very good, but since the death of his daughter Penny, Jon's whole person has "collapsed", he seems to be 20 years old at once, his two eyes have quickly dried up, for him, the purpose of this life is only one, that is, to find the murderer and avenge his daughter.
In order to achieve this goal, Jon did not care about anything, he sold his factory cheaply, exchanged all his assets for cash, found the most famous private detective, rewarded the clues and the murderer in the biggest newspaper, and Jon declared that whoever could find out the murderer was willing to give away all his wealth.
But soon, Jon won't be able to deliver on his promise because he has no money.
Just advertising in the newspaper has already consumed all of Jon's property, and the shy Jon is no longer able to advertise to find the murderer.
When Jon was most helpless, he learned that one of the most famous forensic experts in the United States is Dr. Li Changyu, a Chinese criminal investigation expert, who can be called the "zenith star" in criminal investigation, so he sent an email to Dr. Li Changyu, hoping that Li Changyu could help him find out who killed his daughter and let him not die with regret.
After Li Changyu saw the email sent by Jon, he was touched by this father, and he decided to personally go out and find out the real culprit.
Li Changyu took his team and the police from New Haven to the scene of the crime at that time, although more than a decade has passed, it is still preserved, and they simulated the situation at that time.
First of all, the murderer has been waiting in the parking lot, and at this time Penny drove the Buick car to the parking lot, when Penny stopped the car, ready to get out of the car, the murderer directly pulled open the co-pilot's door and rushed in, and Penny fought with Penny, in the process, the murderer stabbed Penny twice in the chest, and Penny also used the knife in the car to scratch the murderer's left hand.
The injured Penny escaped from the car and fled to the roof in a panic, while the killer chased Penny to the stairs on the roof, where Penny bled too much and fell to the ground, gradually losing her breath.
After waiting for Penny to be completely dead, the murderer left the scene and returned to Penny's car to find out if there was any money, at which time the murderer found that the blood in his left hand was still flowing, so he used Penny's tissue to simply wipe his wound, so he left fingerprints on the tissue box, and bandaged it with his own handkerchief, ready to drive away in his car.
When the killer reached the seventh-floor parking lot, found his car, threw the handkerchief on the ground before getting into the car, and then ran away.
Li Changyu determined that the fingerprints on the tissue box and the blood stains left by the murderer are important physical evidence to solve this case, and at this time, the time has reached the 90s, all kinds of criminal investigation technology has matured a lot, this fingerprint has also been proofread by technology, and it has become clearer, and the blood stains left can also mention some DNA out, and the blood type is different, some people will "hit the blood type", but absolutely no one will "hit the DNA", in this case, it is undoubtedly much simpler to find out the murderer.
But at this time, Li Changyu still has some difficulties, because his motive for the murder is also the same as the judgment of the police in New Haven, this case is a random crime without premeditation, it is a headless public case, the murderer is not for love, not for money, not for revenge, such a case, even if there is evidence, who should be looked for to compare it?
At this time, the sky had eyes, and the suspect actually exposed himself to the water.
In 1994, the police in New Haven received a report from a woman who said that her husband was beating herself up desperately and that she was going to kill herself like Penny, which excited all the police in New Haven, and they quickly found the policeman and arrested his husband.
The man, Korenk, a worker at an auto repair shop in New Haven, was a thin white man, 33 years old in 1973, with a scar on his left hand, O-blood, and from Spain.
The basic appearance is all right.
After the collection of Korenk's fingerprints and blood, compared with the fingerprints and blood left at the scene of the crime, the two parties completely coincided, and the real murderer was finally arrested, but convicting the real murderer became a difficult thing.
In 1999, 26 years after Penny's murder and the murder of Korenk was 56 years old, the case was finally pronounced by the Supreme Court of Connecticut, when Korenk hired three lawyers who were well-known in the relevant fields throughout the United States to defend himself.
As soon as the trial began, Korenk began his performance, shouting that he had not killed Penny at all, and that his legal team was really worthy of his legal fees, and began the "reasoning show" in court.
In the mouth of his legal team, the evidence was all problematic, and the tissue box, most likely Korenk had taken it in the mall before, but did not buy it, and was bought by Penny after putting it back, so it had his fingerprints on it, which was a coincidence.
And about Korenk's O-blood does not say anything, there are many people with O-blood, it is likely to be a coincidence, which is not direct evidence.
Hearing this, Li Changyu immediately sneered and made a rebuttal, in his eyes, the other party's stubborn sophistry was as ridiculous as a clown.
Li Changyu first repeated the defense statement of the opposing lawyer: "You mean, Korenk took this pack of tissues in the mall, but did not buy it, put it back, and then it was bought by Penny?" ”
Then he looked at Korenk again: "So please, how do you know that this package of tissues was bought by Penny, not brought outside, you know that although the place of the incident is a shopping mall, Penny was killed when she entered the mall to park, she has not yet gone to the mall to buy anything, so your description, took the tissues in the mall and put them back, and then bought by Penny, it is impossible." ”
"Second, you may not know, now not only in the blood type test, or in the dna test, the blood type detected at the scene is the same as yours, you can say it is a coincidence, is the DNA detected at the scene and yours the same, do you still say coincidence?" Where did so many coincidences come from! ”
Faced with a mountain of ironclad evidence, Korenk and his team of lawyers were dumbfounded, and after a moment of silence, Korenk finally lowered his head and confessed to the crime.
It turned out that this was really a headless crime, when Korenk just wanted to grab a car in the parking lot, but who knew that Penny was struggling too fiercely, and he was angry and attacked, so he "casually" stabbed Penny twice.
The court then pronounced a verdict and Korenk was sentenced to 20 years in prison.
This case, which lasted for nearly thirty years, was finally cracked by Li Changyu, which does seem to have some elements of luck, but it can also be said that this is "the legal net is restored, and the omission is not leaked."
Unfortunately, Penny's father, Jon, died as early as 1994, and he did not see the scene of his daughter's murderer being sentenced until his death, but if he knew the result of the murderer, he did not know whether he could see it.
