With Borenardz's explanation, Wang Lei and several people finally had a clear understanding of the case.

The first murder occurred 5 days ago.

Dwight? Ritter, 40 years old, came home from work at noon, was shot in the back of the head at an intersection on 14th Street in New York, and died on the spot.

Judging from the surveillance content of several cameras found by the police and the FBI New York branch, this is an unknown suspect wearing a gray sweatshirt and covering his face with a hood to commit the crime.

The second case was three days later at noon, a young black man walking in the subway passage, was walking on the phone while walking, and when the unknown suspect in the same gray sweatshirt and hat passed by him, he suddenly pulled out his right hand in his coat pocket and shot it at the eyebrows of the deceased.

The third case was noon the day before, Julie? Benz, female, 2 years old. When he walked out of the office building to have lunch at noon, he was shot and killed by a suspect in a gray sweatshirt and hat while waiting for a taxi.

At first, the New York police didn't expect it to be a serial murder. It wasn't until the second case, when the media linked the two cases together and hyped them up, that the police suddenly realized.

Then, after the FBI New York Division intervened, the third case happened again 2 days later in the same time period. In desperation, Michelle asked Quantico for help.

When Borenards said this, he was a little stumbling: "The cases all happened in different neighborhoods and different sub-bureaus, so we really can't blame our negligence at the beginning." ”

No one will blame them, and in the history of the United States, many murderers have used cross-district, cross-city, and interstate borders to evade police investigation and pursuit, and some have repeatedly succeeded, and it is not the responsibility of Beronards.

"The coroner's office concluded that the unknown suspect was using a point 22 caliber pistol." David? Francisco added.

Wang Lei groaned slightly, he understood the reason why the murderer used this kind of pistol.

Conventionally, this type of gun is rarely used by civilians, lacks power, and requires accurate shooting at close range. Generally people who do not have a lot of training in live ammunition do not choose this type of firearm.

Even Brenardz, who has been a police officer for decades, is the first time he has seen a murderer use this type of weapon.

"I know that this gun is most used internationally by Israel's intelligence agency, the Mossad, and they like to use it most when they carry out political assassinations." Speaking of which, the person present knows nothing better than Yang Qian.

Although Yang Qian wants to keep a low profile, she still can't help but show her existence occasionally, and it's good to brush it up.

Nodding, Wang Lei said: "I understand why the unknown suspect wants to use this close-range weapon." ”

The streets and subway entrances in New York City, according to the local environmental protection agency, are usually about 100 decibels of noise. And the 22 caliber pistol will not exceed 120 decibels when fired.

In this way, the unknown suspect can be sure that his gunfire will not be detected for a short period of time, as shown in the surveillance.

It is often only after the deceased has been lying on the ground for a few minutes that passers-by will notice that the deceased is no longer breathing.

The last sheriff Rosso who has not been silent? Crowe finally spoke: "We have not found the reason why the murderer used this weapon for Lu, so it turns out that this is the case, and this mystery has finally been solved." ”

Even Yang Qian's eyes widened, she was familiar with this weapon, but she was not familiar enough to know the decibel size of the gun when it was fired, which required very well-read knowledge to remember these details.

"We've also investigated......" Michelle, who sent Julie back, stood at the door, Wang Lei occupied her place, she was reluctant to go in and stand in the middle of the room, that would make her feel that she couldn't control the situation.

The New York branch investigated the three deceased, who had no personal contact with each other, and did not find that the three had ever been to any of the same locations.

"I think this one is very similar to Sam's son, what do you think? Except that no letters were written to the media. Brenardz was a little frightened, and his voice trembled.

Unpremeditated random killing, at first glance, it seems like this, but this time there are two differences between the unknown suspect and Sam's son, Sam's son uses a large-caliber pistol, and he drives around New York at night, and whoever he meets is unlucky.

"This time the unknown suspect was very bold and chose to shoot at noon when the crowds were at their highest, and I think he must have been trained to some extent. Coupled with the special caliber guns he used, I think there is a high probability that it was a recently retired military man. Coleman had been pondering, in his mind a different synthesis of various aspects of evidence and limited clues.

No one objected to Coleman's opinion, and he was very reasonable. Michelle's eyes lit up even more, and he took out the phone and immediately ordered: "Check the information of veterans who live in New York within 3 months, and then contact the CIA and ATF to get the information of all the 22-caliber gun owners in New York for comparison." ”

Khalid? Mohammed hurried to the entrance of the 59th Street subway station with a shoulder bag on his back, his right hand in his pocket.

The subway came in, there were a lot of people, and as an Arab American, although his mother was American, he was still discriminated against in his short 20 years of life, which was one of the main reasons why Khalid was willing to come to New York from Washington D'C to work alone, and the salary was secondary.

On the surface, all aspects of the United States are vigorously opposing racial discrimination, but in daily life, those sudden glances and unconscious intervals still make Ed deeply taste that racial discrimination can be said to be ubiquitous in the United States.

It's like now, when he is standing in a crowded subway, the people around him immediately retreat desperately, moving a small blank space for him.

Accustomed to this, Khalid would not take it to heart at all. His left hand grasped the armrest, and his right hand remained in his coat pocket. Opposite was a white woman with her child, and when she saw Khalid's gaze on her, the white woman couldn't help but shrink back and hold the child tightly in her arms.

Looking around, everyone was avoiding Khalid's gaze, maybe it was still a good match for mother and son, Khalid thought to himself.

It didn't take long for a pleasant electronic synthesized sound to start announcing the station: "Spring Street has arrived at ......"

The white mother, who was already sitting at the door, quickly stood up, grabbed her child, and as soon as the car stopped, the door was only half opened, and she hurriedly squeezed out.

As soon as they got out of the car, the mother and son immediately walked briskly, and the child was almost dragged forward by his own mother. Khalid also quickly got out of the car, chasing the mother and son, shouting, "Hey, hey, hey......"

The white woman glanced back, pulled the child and ran, disappearing around the corner of the exit in an instant, the fear in her eyes that made Khalid feel so accustomed.

Spat hard, Khalid liked this country at the same time, but also hated the racism that was deep in the country's bones.

His right hand was finally removed from his coat pocket, along with a folded map of New York. In the half month since D'C came to New York, Khalid's most painful thing is that he often gets lost.

It is a huge reinforced concrete city, and if you are not careful, you can get lost in it, both physically and mentally.

Stopped, looking at the dwindling flow of people around him and the red signal lights of the subway in the distance, Khalid helplessly lowered his head and began to look at the map carefully, he was going to apply, he must find the shortest distance, otherwise he would be late.

A thin voice in a gray sweatshirt and hoodie approached Khaled, his head bowed so he couldn't see his face, his hands in his pockets.

His steps were light, and Khalid, who was so engrossed in his map, didn't notice it at all. Just as he walked behind Khaled, his right hand was pulled out of his coat pocket.

The black pistol had been in the hand of the hoodie, and after raising his hand to this Khalid, he pulled the trigger.

"Bang", the sound was very soft, the map in Khaled's hand was released and fell to the ground, and the person fell down at once, motionless.

The hoodie then walked past Khalid and ran towards the exit.

A quarter of an hour later, Wang Lei and his entourage arrived at the scene, and the three sheriffs and Michelle also came.

Looking at the corpse on the ground, listening to the patrol policeman who arrived first talking about everything he knew, Khaled's body was lying on the ground, Wang Lei felt very uncomfortable.

"This is the fourth deceased, and the speed at which the unknown suspect kills is accelerating, indicating that he is about to enter the stage of losing control." After looking at the wounds, Wang Lei has confirmed that this is the same murderer as the previous 3 serial murders.

This was also confirmed by the coroner who arrived later, ordering a 22-caliber pistol. From the surveillance video mobilized by the Spring Street Subway Monitoring Center, everyone saw the back of the familiar sweatshirt and hat.

After returning to the FBI branch in New York, Michelle added Khaled's name to the case analysis board and heavily wrote the "4" symbol.

Once a serial killer loses control of his emotions or is on the verge of a mental breakdown, the speed of killing will accelerate, which is a test that has been summarized for a long time.

Maybe another day or half a day, maybe a few hours later, maybe the news that the fifth victim had been shot dead.

Everyone's faces were much gloomy, Wang Lei thought about it, and while asking Yang Qian to open the map of the New York city area, he proposed to the three sheriffs: "Why don't you increase patrols in various neighborhoods." For example, in the 14th Street, 44th Street, 59th Street and other high-traffic neighborhoods? ”
