The Last Killer

In the criminal investigation and analysis office, Kensen showed the first-line information without any concealment, and got into a heated discussion with Li Biqing, and even expressed great tolerance for the stuttering Chinese accent in English.During this period, he invited the other party to participate in the analysis of the case many times, and finally reluctantly asked for his mobile phone number.When the two shook hands and bid farewell, Rob couldn't help but glanced at Leo, and sure enough, he found the hidden pride and trouble on his partner's face.

"When I found out that the first girlfriend that Xi Weier made was a super hot girl, I had the same mentality." He patted Leo's shoulder empathetically, "I'm happy to see it, but also worried. It's very contradictory. Okay. When I don't have a brotherhood complex, I adjusted it in two and a half, which may be a little difficult for you, man."

Leo pushed his hand away with a downcast face, "Neither do I! I just don't want him to get involved, understand? He's just an ordinary student, reading books, playing with PDA, or having a girlfriend to go to the restaurant for drinks Afternoon tea, this is his life, not like us, chasing after some perverted murderer, watching scenes of bloody flesh and bullets flying all the way, and finally reaping a lot of grief, despair, hatred, curses, etc. Wait for negative emotions! This is our battlefield, and I don't want to drag him in!"

Rob said disapprovingly: "He is not a thoughtless rag doll, let you push it around. You think this is a battlefield, but it may be a stage for him to display his talents and talents. If you use 'for you' You can interfere and plan other people's life paths at will with a good 'excuse, that is your own selfishness, Leo, you will regret it in the future!"

Leo's face was gloomy and he didn't say a word.

"I know you know it in your heart, but you just can't let it go. Well, being stubborn is not a bad thing, but if you get to the point of being paranoid, you should see a psychiatrist." Rob jokingly took out his phone, "I know a very An excellent doctor, who has deep research on various mental diseases and disorders, and also serves as a relationship guide, do you need to leave his phone number?"

"Fuck you!" Leo punched him and couldn't help laughing.

After this conversation, Leo got Li Biqing a temporary access card, allowing him to enter and exit the office building of the FBI branch as an intern. Of course, the authority is not high, and some floors are classified as confidential areas and cannot be set foot.Even so, the Chinese-American boy was still extremely happy, and the federal agent, who was staring deeply at him with shining grateful eyes, felt a little flushed and hot.

The language school's courses were arranged in the morning and evening. After eating at noon, Li Biqing took Leo's ride as a matter of course, and spent the whole afternoon in the Criminal Investigation and Analysis Section to help Kenson—the latter was like a treasure He carried his new assistant with him wherever he went, and his rippling smile gave Leo the urge to drag him to the underground combat training ground for a "comparison".

Just 11 days after the DEA office murder, Victim No. 5 lay on the steps outside the gates of the Municipal Courthouse.It was a bailiff who was about to transport prisoners. With many bailiffs, he was shot 200 meters away. The first bullet hit him in the chest. When he fell backwards, two more bullets Injected into the abdomen, he died instantly.In his jacket pocket, like the city policeman who died at the gate of the police station, there was a black pawn, and it was unknown when and how the murderer put it in.

Before the police had time to catch their breath, the No. 6 victim appeared the next day—a mounted patrol policeman on night shift. His motorcycle was tripped by a chain that flew suddenly. He was twisted before he could get up from the ground. Broken cervical spine.The murderer was so powerful that his head was turned 180 degrees backwards and hung on his back, just like a scene in a horror movie.There was also a pawn left on the scene, the white soldier.

All of a sudden, the public was raging, the murderer's vicious methods and arrogant attitude, especially the extremely targeted target, aroused the anger of the entire law enforcement system.The questioning and criticism from the media and the accountability and supervision from the top of the system turned into heavy pressure on the task force. Even Leo also received a call from the FBI headquarters, ordering him to help the city police arrest the murderer as soon as possible and contain the situation. expand further.

For this reason, Leo has not had a good night's sleep or eaten a comforting meal for three days, and even Rob, who is always foolish and glib, has a serious look on his face.The abominable thing is that there are still very few traces that can be traced. The 5.56mm NATO standard rifle bullets taken from the bailiffs have a wide range of uses. In addition to military use, they are also widely used in various small-caliber sports rifles as shooting competitions in sports games. ammunition, so it is impossible to find out the model of gun used by the murderer.More than half of the remaining footprints were found in the hidden place where the mounted patrol police were murdered. Judging from the texture, they were a pair of ordinary military boots. After the footprints were completed, according to the formula of ×6.876, the murderer was estimated to be about 6 feet 2 inches (1.88 meters) tall. , according to the comparison of the depth of the footprints, it is speculated that the weight is about 200 pounds (91 kilograms).

On the other hand, Li Biqing had a very important conjecture.Leo was driving alone in a black Chevrolet Suburban on his way to Thomson Prison when he got the call.Because when the police searched near the prison, they found a suspected shooting point.

The double-layer power grid on the outer wall of the prison is 4.5 meters high, and the sentry tower is as high as eight or nine meters. The Barrett M33 sniper bombs are either Barrett M82 or M107. The effective range is 1850 meters, and the maximum does not exceed 2100 meters. Within this range, it is not very difficult to find a shooting point with a sufficient height and 100% field of view according to the ballistic trajectory and pitch angle. At most, it is time-consuming to search and eliminate suspicious points one by one.The police who searched found traces of climbing and scraping on a 800-meter-high tree more than 12 meters away from the opposite bank of the Mississippi River next to the prison. It is suspected that the murderer hid in the treetop and fired.

Leo turned on the steering wheel, connected to the Bluetooth headset, and heard Li Biqing say to him on the phone: "1, 8, 3, 11, 1, do you know what it is?"

"The time interval between each murder case." Leo answered familiarly.

"At the same time, it is also the number of steps between captures."

"Eat child?"

"Yes. Leaving aside how many steps the first eaten white pawn left the game, the second eaten black pawn was one step away from the previous white pawn. The black pawn was eaten after eight moves, and the white horse was eaten after three steps. Another ten One step is a black pawn, one step is a white pawn."

"So, the two murderers choose the time and target of the killing based on the capture of the chess pieces?"

"Exactly. Moreover, I suspected that this was not an ordinary game, so I had someone write a program to substitute the capture situation into the chess encyclopedia of chess, and sure enough, I found the most matching game—the famous game Battle of Deep Blue!"

"What battle?" Leo was not keen on chess and asked in confusion.

Li Biqing explained: "On May 1997, 5, Kasparov, the top chess master, played the sixth game against the IMB supercomputer 'Deep Blue'. In this critical game, with powerful computing power The computer defeated the wisdom of the human brain, and Kasparov was completely defeated. The two murderers chose this historic chess game as a platform for confrontation, which can be said to have a profound meaning. We can extend it: the human brain and the computer The battle of nature and man-made—the battle of cold weapons and hot weapons, the battle of hand-to-hand combat and mechanical firepower! Have you found something similar?"

Leo immediately grasped the key point: "So what was left in the shooting was the black piece, because the white piece took it, and the murderer holding the white piece was obsessed with showing his means and ability to kill with hot weapons, while the black piece held The murderer is keen on killing people with cold weapons after capturing. These two people have different ideas, so they compete with each other. This is not an ordinary serial murder, but a game between white and black; A rivalry; it's a game between two killers using the city as a chessboard and human lives as pieces!' Now I finally understand what you mean!"

"That's what it means. The problem now is that the chess game is not over yet. According to the game record of that battle, there are still three captures in the back, namely the White Knight, the Black Queen and the White Castle. If the murderer did not tamper with the game, the next The white knight who was eaten was the fourth step after the white soldier, counting the time, it is today!"

Leo slammed on the brakes. Amidst the sharp whistle of the brake pads and the almost horizontal body, he gritted his teeth and said, "Today! The seventh victim! Who will it be?"

"Unfortunately, I can't guess this." Li Biqing's low voice came from the other end of the phone.

"You've done a good job." Leo comforted, "You don't need to think about how to stop it. We will leave the matter of catching the murderer to us. You just need to continue to analyze and speculate."

"En." The Chinese boy responded with a soft nasal voice, and then continued: "Leo...be careful."

"Don't worry, I will." Feeling the concern in the other party's words, the federal agent replied softly, then hung up the call and restarted the car.

After continuing to drive for a few minutes, there was a sudden "boom" sound from behind the car, and Leo immediately felt the car shaking and tilting to the right, and he could hardly hold the steering wheel.

Flat tires, the hell with this country gravel road.He cursed secretly in his heart, stepped on the pedal lightly repeatedly, stopped the car slowly on the side of the road, opened the door and got out of the car to check the situation.

Sure enough, the rear tire on the right side was blown out. He bent down to check the tire, and when he saw the triangular iron cones pierced into the rubber, his heart skipped a beat: This was not an accident!A sense of crisis arose spontaneously. In the flash, he inserted his fingers into his coat, pressed the bullet of the quick-draw holster, and took out the handle of the gun—but it was still a step too late. His ankles seemed to be caught by a pair of steel. The tongs were clamped tightly, and they were dragged backwards violently. The center of gravity was out of balance, and the whole body fell down!

At the moment of falling to the ground, the scene of the next second appeared in Leo's mind: a sharp weapon was about to hit him from behind, with the blade slanting upwards, avoiding the ribs and directly piercing his lungs. The screams were too late to exit, and he fell dead beside the car in an instant!

Death's scythe slashed, murderous and piercing, the skin on his back almost felt the icy wind of the knife, and the shivering feeling like an electric shock rushed straight from his feet to his spine.At the critical moment of life and death, he bent his left forearm to support the gravel road near his nose, and at the same time tightened his thighs with all his strength. His feet broke free from the restraint like two twisted wires, and turned over suddenly. Before he had time to adjust the focus, he pulled the trigger with his right hand in the direction of the shadow of Yuemo without hesitation.

A cold gray light flashed past his eyes, and there was a muffled knock on the hard polyoxymethylene shell of the Glock 18, and the pistol flew out.Leo held his right wrist that was in pain due to the huge shock force, turned over and rolled two or three meters away.

He parried the fatal blow from his attacker, but paid the heavy price of losing his weapon.Originally, there was a spare XR9 pocket pistol stuck in the ankle, but it was pulled out at the moment of the attack.

However, he also took the opportunity to see the appearance of the attacker clearly. Although the opponent was wearing a hood, he could only see a pair of small eyes shining with cold light. This is a big white man, his height and weight are similar to the data obtained from the footprints at the murder scene - this man is very likely to be the killer who left the white chess piece!

It turned out that the seventh victim selected today was himself!While the opponent raised his knife and rushed over, Leo, who was lying on his back, put his hands on the ground and kicked the opponent's shin with both feet.His squat strength reached 350 kg, and anyone who was kicked by this kick would not feel well, or even directly fractured.But when Leo kicked the opponent's calf muscles firmly with this leg, it felt as if he had kicked on an iron plate, and the shock force made the soles of his feet numb with pain.

The masked murderer took the opportunity to cut across his calf with a knife, leaving a bloody wound on his ankle. If Leo hadn't shrunk quickly, the ligament might have been severed by the knife.

This is a master of fighting!Leo endured the pain and jumped up with a carp. His right leg violently kicked the opponent's wrist holding the knife, but he was easily avoided by raising his arm in time.The opponent stepped forward the moment he dropped his leg, and the cold blade stabbed straight at the kidney on his right waist.The speed of this knife was too fast, and when he was about to grab his leg, Leo couldn't dodge it, so he had to turn around and twist his waist muscles, and got a hard knife on the back, and his suit was hit by the sharp blade. It was scratched, and the gushing blood instantly stained the dark cloth.

He was stabbed twice in succession. Although the wound was not deep and did not hurt his vitals, the constant blood loss and severe pain still severely reduced his speed and physical strength. Leo was even more terrified: the opponent's skill, even with fighting Compared with the expert Anthony, it is not much better.This is no longer a level he can confront head-on!

Seeing the light of the knife cutting through the air again, a sense of despair rushed straight up from the bottom of his heart, like a jet of high-pressure water jetting out from a hole in the ice, which almost froze Leo's brain.But his survival instinct attacked decisively at this moment, and he smashed the handful of gravel secretly held in the palm of his hand when he fell to the ground, and hit the opponent head and face!

The masked murderer subconsciously raised his arms to cover his head and face. Taking advantage of this fleeting opportunity, Leo compressed his leg muscles like a spring and jumped out. He jumped three or four meters away in the blink of an eye, and flew towards the grass beside the road. The Glock 18 in.At the same time as the opponent rushed over, he grabbed the handle of the gun with a slight advantage of one second.There was no need to activate the trigger safety, and he quickly pulled the trigger with his finger, and fired three bursts as soon as he turned over.

The moment Leo snatched the pistol, the masked murderer judged that the situation was over. The easy raid that he thought could kill him with a single knife, was dragged into a hard bone by this boy-like federal agent.He made a decisive decision, leaped sideways before the gunshots sounded, and rolled into a cornfield that was as tall as a man beside the road.

This gravel road is not far from the rural town of Thomson. Although it is quiet and uninhabited, there are still many plowed fertile fields beside the road. The corn in summer has already headed, and the green gauze tent covers a large field. end.The figure of the masked murderer arched a few times, and quickly disappeared into a green curtain. The few bullets that Leo fired immediately after, only set off a wave of air waves.

The scorching silence descended on this country road again. Leo took a deep breath in the smell of gunpowder smoke from the muzzle. He swallowed slowly the sound of his beating heart violently beating his chest. The cloth was thoroughly soaked with blood and sweat.

A burst of dizziness after blood loss descended on his brain like a flock of flying vultures. He took off his suit jacket, tore off the sleeves and tied it around his waist twice tightly, strangled the wound on his back, and tied a circle around the wound on his ankle. He got up and put on the spare tire with difficulty, then returned to the driver's seat in the car, and started the car.

His current location is 230 kilometers away from the downtown area of ​​Chicago. It is impossible to turn back and seek medical treatment. He can only continue to drive forward to the town where Thomson Prison is located—hopefully, there will be someone in that remote town with a population of less than 600. A clinic that can sew up his wounds.

20 minutes later, a black Chevrolet Suburban parked in front of a bungalow on Main Street in Thomson Township. Leo glanced at the eye-catching red cross sign on the signboard, walked into the glass door with weak steps, and stood there covered in blood. In front of a doctor in a white coat, he took out his ID card before the other person turned pale in shock: "FBI, I need your help..."
