"Bang!"

The violent impact was accompanied by a loud bang, piercing the night sky in the east that was gradually white.

3:10 a.m., Tanigawa City.

Under the raging fires in the sky, the flashing glare lights of police cars, ambulances, and the fire trucks that are still rushing all suggest that this coming dawn is not peaceful.

Four kilometers away from the provincial highway S361, a large truck full of red containers stopped on the side of the road to the east. One of the containers at the back of the truck had been blown to shreds, and the remaining containers were still leaking liquid.

Not far from the rear of the large truck, there was also a yellow Camaro emitting billowing smoke, and half of the body was burned to the ground and only a frame remained. It took a lot of effort for the fire brigade to extinguish the fire. The entire scene was littered with fragments of car lights and bumpers, mixed with bloodstains, and a mess. Occasionally, a few cars passing by the scene of the incident were afraid to avoid it.

Police officers and doctors wearing gas masks shuttled through the scene, busy and nervous. Although it was only summer in Tanigawa City, their clothes were already soaked with sweat.

The driver of the truck stood tremblingly in the middle of several policemen to be questioned.

"I... I'm inside..."The frightened truck driver kept rubbing his hands. The small man's face was pale, and he only felt a tightness in his throat and gurgled and swallowed.

"What the hell is going on?" Lifting the cordon and entering the center was Zhang Lei, director of the Guchuan City Public Security Bureau. At nearly half a hundred years old, he has an inconspicuous V-shaped scar on the left side of his face. He was followed by Li Yingbo, a forensic doctor at the city bureau, and several other young policemen.

"Zhang Ju!" Wang Min, a traffic police officer of the Longhua District Traffic Police Brigade, who was inquiring about the driver of the big truck, saluted and greeted Zhang Lei softly.

"Good work!" Zhang Lei nodded and gestured to Wang Min, and then looked at the truck driver: "What's the matter?" Don't be nervous, speak slowly. ”

"Hmmm! It was almost half past two o'clock..."The driver of the big truck drank the water handed by the traffic police and calmed down a little: "I mainly run the freight from Xinji to Canglang." Yesterday morning I pulled a cart of nitroglycerin synthetics from Xinji to Canglang. It was too sleepy to drive here in the middle of the night, so I pulled off the provincial road and parked on the side of the road to squint for a while. I felt like I had just fallen asleep when I heard a 'bang'! I got up in a daze and saw that the back of my car was on fire, and I was scared..."

Zhang Lei patiently listened to the driver of the big truck, turned around and lifted the cordon and returned to the police car with a pale face. Immediately after Wang Min closed the notebook, he came to Zhang Lei's car and saluted and reported: "Zhang Ju, we have retrieved the dashcam of the large truck, and at the same time, after interrogating the driver of the large truck at the scene, it is determined that the information he described about the incident is basically the same as what was captured in the on-site surveillance video of our other center. We have followed the process of questioning and have made on-site transcripts of the truck driver while retaining his identity. Is it possible to let him go? ”

Zhang Lei nodded. Forensic doctor Li Yingbo carried the investigation box, opened the other side of the car door, and sat in the car, his face full of exhaustion.

Lee Ying-bak looks a lot like Brown Bear. He had a swarthy face with a pair of round-rimmed glasses.

"One of the deceased at the scene was a yellow Camaro driver. Judging from the uncharred items of the deceased left at the scene, it is preliminarily determined that..."

"Could it be a premeditated murder?" Zhang Lei looked at Li Yingbo and shook his head, interrupting what he was going to say next.

"Eighty percent of it was an accident." Li Yingbo pursed his lips, with a slight regret and helplessness on his face: "The body was burned to the point of almost charring, and we need to return to the bureau for further autopsy to be sure." ”

"Well," Zhang Lei lit a cigarette, took a slow puff, looked out the window and gently exhaled the smoke ring: "When will Lao Sun come back?" ”

"It should be today, right?" Li Yingbo leaned back in the seat behind him and slowly closed his eyes.

The first rays of the morning sparkled into the car.

"Don't tell him yet." Zhang Lei pinched out the remaining half of the cigarette and closed the window.

......................................

"Zhang Ju!" As soon as Zhang Lei yawned and returned to the office, Sun Meng's cold hello really scared him a lot.

"Oops! Old grandson! Zhang Lei poured Sun Meng a glass of water, sat at the desk opposite Sun Meng and looked at him.

Sun Meng was dressed in khaki casual clothes, and although her face was a little tired, she couldn't hide the sparkle in her eyes.

"I said Lao Sun, are you an iron-beaten King Kong? After half a month, let's go back and rest first, what time is it," Zhang Lei subconsciously raised his wrist and looked at his watch: "It's half past seven in the morning!" Do you think it's appropriate for you to suddenly appear in my office and scare me? ”

"Zhang Ju," Sun Meng turned the swivel chair, picked up a handbag from his feet, put it on the table and gently pushed it to Zhang Lei, and said with a smile: "The best Meiyang Tieguanyin, sister-in-law's favorite, take it back and give it to sister-in-law to drink!" ”

Zhang Lei rubbed his nose and coughed lightly twice: "You kid is blatant bribery!" ”

Sun Meng smiled heartily, leaned his head forward, and deliberately lowered his voice and said, "Lao Zhang, you just said that with our merits this time, the position of the captain of the criminal police, are we slightly better than his Lao Su?" ”

"Hmm..." the corners of Zhang Lei's mouth trembled slightly, and a trace of imperceptible sentimentality flashed in his eyes.

"How's it going, this business trip went well, right?" Zhang Lei eased his mind.

"Hey! Sensei! Unbelievably smooth. When we arrived in Mayan, the local police had already retrieved the handwriting results, and there was no doubt that there was a huge amount of fraud! Sun Meng excitedly reported the business trip.

"Good! Great work! Zhang Lei nodded with satisfaction.

"Knock knock!" With a quick knock on the door, Li Yingbo appeared in front of Zhang Lei's door with an autopsy report in his hand, interrupting the two people who were talking.

"Zhang Ju!" Li Yingbo said as he walked inside: "The autopsy results are out, indeed..."

"That's right, old grandson!" Zhang Lei hurriedly waved his hand at Li Yingbo and signaled him not to speak yet. "Thank you for your hard work! I'm giving you a vacation today, go back and have a good rest! ”

"Huh? Lao Zhang, are you eccentric! Captain of the criminal police, are you still facing Lao Su about this! Sun Meng smiled and stretched out her finger and nodded at Zhang Lei, stood up and walked towards the door: "Hey, by the way, why didn't you see Lao Su today?" I'll go around his house. ”

"Hey! Old grandson! Li Yingbo subconsciously shouted, and Sun Meng was stunned: "Ah? What's wrong? ”

"It's okay, Lao Su doesn't seem to have come yet." Lee Yingbo paused unnaturally and muttered.

"Ah," Sun Meng rubbed his neck and yawned, and the phone rang just then. It was Guo Tanya, the little girl who called.

"Hey, Tanya?"

"Brother Meng, when are you arriving?" On the other end of the phone, Guo Tanya was a little annoyed.

"Huh? I... Where am I going? Sun Meng shook his head vigorously, and running around overnight made him still a little confused.

"Brother Meng, didn't you promise me to come to the Children's Day event in the welfare institute before! See for yourself, what day it is! ”

"Oops!" Sun Meng patted her head, and her tone was full of apologies: "I'm sorry, I'm sorry Tanya, I almost forgot about it after running for most of the night, I'll go!" Sun Meng hung up the phone and trotted out of the public security bureau and drove to the welfare home.

The Tanigawa City Welfare Center is located on Jingqi Avenue to the east of Tanigawa City. It's only a 10-minute drive from the Public Security Bureau. As soon as Sun Meng's car turned into the welfare home, Guo Tanya greeted him excitedly. As soon as Sun Meng opened the car door and stepped out of the car, Guo Tanya hugged him.

"Brother Meng~~" Guo Tanya screamed coquettishly.

"You'll always be like a child who doesn't grow up!" Sun Meng patted Guo Tanya's back, her face full of doting. "I'm sorry, I'm sorry Tanya! I said that Lao Su was not there when I returned to the bureau early this morning, and the feeling was that he came early! Sun Meng looked around and asked happily.

"Huh? Isn't Brother Su on a business trip? He told me the day before yesterday that he wasn't coming! When Guo Tanya heard Sun Meng mention Su Ruo, her face was somewhat lost.

"He's on a business trip? Why didn't Lao Zhang tell me, what kind of case is mysterious..."Hearing Guo Tanya's words, Sun Meng's expression was also quite surprised.

"Okay, Brother Meng, let's not talk about Brother Su first. You haven't been back in a long time! I'll take you for a spin first! After the renovation last year, the welfare home has changed a lot! Guo Tanya took Sun Meng's hand and walked inside.

The sun shone on the two people, pulling a long shadow on the ground.

"Look at you!" Guo Tanya pointed to the newly repaired swings in the yard: "Do you remember when I was a child, the three of us always fought for the two swings." ”

Sun Meng smirked, and Guo Tanya's excited big eyes sparkled, which was also touching.

"Look at that, the wall has been heightened, too! When I was a child, you and Brother Su always went out from there to play secretly, I couldn't go up, I was so anxious that I could only cry, so you brought the marshmallow back for me to eat. ”

"Tsk, it's changed a lot." Sun Meng's mouth couldn't stop praising it. "It's been a long time since I've been back..."

"How are Tanya, how are you doing?" Sun Meng looked back at Guo Tanya, still doting in her eyes.

"Well, the kids are much more worry-free now than we were back then." Guo Tanya smiled sweetly, revealing two small tiger teeth, and a dimple spread on her cheeks.

"Okay, Brother Meng, let's go in and see how they are preparing for the evening event."

"Let's go!" Sun Meng followed Guo Tanya, and the two of them walked into the main building of the welfare home one after the other.

..........................................

"Say it, Lao Li." Zhang Lei took the autopsy report and threw it directly on the table, and the whole person leaned back in the chair, looking a little decadent. He sighed again and closed his eyes deeply.

"Zhang Ju," Li Yingbo said softly as he picked up the autopsy report and flipped through it, "We did a detailed autopsy on the almost charred corpse. Judging from the remains of the pelvis, the deceased was male and aged between 25 and 30 years. The length of the vertebral body is determined to be between 1.75 meters and 1.80 meters before death. The body was in the shape of a fist. The muzzle and nose of the corpse were clean, but the respiratory tract was slightly edematous and congested. There was also no significant damage to the car's thyroid cartilage, and we ruled out mechanical asphyxia. ”

"Ahem..."Zhang Lei clutched his chest and couldn't stop coughing a few times.

Li Yingbo was stunned and put down the autopsy report: "We judged that the only possibility based on the brakes and impact marks at the scene was that the deceased was driving due to fatigue before his death, and it has been raining in our city for several days recently. However, due to the deployment of the vehicle's airbag after the impact, the driver did not die due to the impact. However, after falling into a coma, he inhaled a large amount of harmful gases and suffocated, and was burned to death by the fire ignited by the explosion. ”

Zhang Lei frowned tightly when he heard this: "Go on." ”

Li Yingbo nodded and continued: "Combined with the testimony of the driver of the large truck at the scene, coupled with the analysis and comparison of the clothing and body shape of the yellow Camaro driver in the video surveillance, and at the same time, we found a series of clues such as the remaining police uniform, police officer ID, and the comparison between the extracted DNA on the half-charred back seat of the vehicle, we can confirm..."

Li Yingbo bit his lip a little and muttered: "We can confirm that the deceased is the deputy captain of our criminal police team, the first-class police inspector, Su Ruo..."
