Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

"Let's go to the scene!" Wang Shuai and Zhang Hui led the team to the path outside the factory. The ground was covered with thin ice in the cold winter. They stepped on the mud and searched carefully with flashlights. Finally, they found a cigarette butt in the grass by the roadside. Zhang Hui carefully put the cigarette butt into the evidence bag: "Maybe this is the breakthrough."

They continued to follow the route the van was taking, and a surveillance camera at a gas station clearly captured the scene of the van refueling. Although the license plate was still blocked, it can be seen from the picture that in addition to the driver, there seemed to be another person sitting in the passenger seat, but due to the angle, the appearance could not be seen clearly.

The subsequent investigation mainly revolved around the van.

After listening to the report in the office, Lu Chuan gave an order: "There are still 17 surveillance stations along the Beiyang River that have not been checked. Focus on logistics parks and waste recycling stations. There are many vehicles coming in and out of these places, and it is easy for fish to slip through the net." Zhang Hui crushed the instant noodle box in his hand, and the sound of plastic breaking was particularly harsh in the conference room: "Understood, if he is alive, I want to see him, and if he is dead, I want to see the car."

At four in the morning, the riverbank was covered with mist. Wang Shuai's flashlight beam split the darkness, illuminating the crooked wooden sign "Integrity Scrap Recycling". Three dogs suddenly barked and rushed towards the iron gate, the iron chain creaking. "Who is it?" The second-floor window was pushed open, and the bald boss wrapped in a flowery cotton jacket leaned out half of his body, "Collecting junk in the middle of the night?"

"The police are investigating a case. Please cooperate with us in checking the surveillance." Zhang Hui held up his ID card and the searchlight swept across the piles of cardboard boxes in the yard. The boss put on his slippers and cursed: "The surveillance broke down last month and it can't be repaired." Before he finished speaking, Wang Shuai had already climbed up to the roof along the rusty iron ladder. His voice came with the sound of the wind: "The camera cable was bitten off by a rat, but the memory card is still there!"

In the musty duty room, the old computer made a clicking sound when reading. Wang Shuai stared at the screen and suddenly stood up, his chair making a harsh sound on the concrete floor: "9:17 am on September 2!" In the picture, a white van rolled over the gravel road. The moment the headlights swept across the waste pile, the passenger window was half lowered, revealing half of an arm wearing a black glove.

"Enlarge the license plate!" Zhang Hui almost stuck to the screen. But the license plate was covered with mud, and only the metal reflection could be vaguely seen. Technician Xiao Li rushed in with equipment, typing on the keyboard as fast as rain: "The outline of the car model looks like the 13 Jinbei Haisheng, but the shape of the taillight is wrong." He suddenly gasped, "Look at the rearview mirror! The trunk number is reflected in it!"

When everyone gathered around, Wang Shuai had already circled three red dots on the map: "There are no more than 200 such numbered vans in the city, and the focus is on transport companies and self-employed individuals." Before he finished speaking, Zhang Hui's cell phone rang. After hearing a few words, his face suddenly changed: "Captain Lu, the Transportation Bureau reported that this car registered under the name of 'Hongda Building Materials' was just scrapped three days ago!"

When the police car rushed into the Hongda Building Materials Factory, the gatekeeper was feeding the parrot. "Scrapped car? It was sold to the junk collector a long time ago!" The old man cracked melon seeds and pointed to the backyard, "It was sold to Liu Laosan of Chengxin Scrap Station, who said it was to be dismantled as metal sheets." Wang Shuai and Zhang Hui looked at each other and thought of the bald boss who had tried to stop them half an hour ago.

When they returned to the scrap yard, the yard was full of newly collected scrap metal. Liu Laosan was directing workers to cut the frame of a van, sparks flying. "I didn't know there was anything wrong with this car!" He was still quibbling as he was pressed on the pile of metal sheets, "The grandson said he was in a hurry to use the money, so he sold it for 30,000 yuan." Zhang Hui found half a cigarette butt in the gap of the driver's seat, and the friction sound of the evidence bag made Liu Laosan shut up instantly.

The technical department compared the DNA of the cigarette butt with the dandruff in Li Xiaomin's fingernails overnight, and the match was 99.9%. However, the frame number had been corroded by strong acid, and the only breakthrough was the blurred factory code on the gearbox. Yang Sen wore goggles to operate the laser scanner, and the blue light beam wandered on the metal surface: "The first three digits of the code are 2012, indicating the year of production." He suddenly stopped, "Wait, there are overlapping engravings here!" The image magnified 200 times showed that another set of numbers was faintly visible under the original factory code. When the chemical reagents faded the surface rust, the words "HG20180907" appeared. Zhang Hui's fingers flew on the keyboard, and the moment the vehicle management system was refreshed, the whole laboratory was boiling - this string of numbers corresponded to a passenger vehicle that should have been scrapped three years ago. The registered owner was Chen Yonggang, who was Chen Yongqiang's cousin!

Lu Chuan tapped the whiteboard with his fingers: "Chen Yonggang disappeared half a year ago due to gambling, but he still has a 'Yongsheng Car Rental Company' under his name." He called up the surveillance screenshots, "Look at the wheels of this van, they are exactly the same as the features of the vehicles leased by Yongsheng Company." In the picture, the driver in a baseball cap lowered his head to light a cigarette, and the chin outline reflected by the lighter flame was highly similar to the photo on Chen Yonggang's ID card.

When the commandos surrounded Yongsheng Company, the garage was empty except for oil stains. But in the drawer of the finance office, a stack of car rental contracts gave away the truth. On the 16th rental contract, the tenant's signature was "Li Qiang", but the contact number was an invalid number. Zhang Hui picked up the contract with tweezers and held it up to the light: "The fluorescent reaction of the paper shows that this was printed with a thermal printer, and the ink can be kept for no more than two weeks."

The more critical discovery came from the parking lot's scale, which recorded a loaded vehicle at 17:1 a.m. on the 58th.

He checked the surveillance footage from gas stations along the way, and at a Sinopec station, the surveillance clearly captured the driver taking off his mask while refueling - although the image was blurry, the dark red mole on his Adam's apple completely matched Chen Yonggang's features.

And a major turning point occurred during the investigation of the case.

In the technical analysis room of the Criminal Investigation Brigade, the blue light of the fluorescent screen made everyone's faces pale. Yang Sen's fingers paused on the keyboard for half a second, and the test report spit out by the printer was not yet dry: "Chen Yongqiang's DNA is a perfect match with the bloodstains in Li Xiaomin's room, with a probability of 99.999%." The paper slid in front of Lu Chuan and overlapped with the missing Chen Yonggang's missing investigation notice, forming a strange parallel.

After the police initially determined that the brothers Chen Yonggang and Chen Yongchang were major suspects in the crime, although the two men were missing, their families had found and extracted their DNA information, and obtained the clothes of Chen Yongqiang and Chen Yonggang in their homes, and determined the final DNA information of the two men.

When comparing the results, no problem appeared that no one had expected.

"That's impossible." Zhang Hui grabbed the report and wrinkled the edge of the paper in his palm, "Could Chen Yongqiang be the victim?
According to the clues the police have found, it is very likely that the brothers Chen Yonggang and Chen Yongqiang committed the crime together. Of course, it should be Chen Yonggang who dumped the body. Although the other party had tampered with the car, the police were able to find these things after the initial inspection. But now, during the inspection process, it was found that the deferred information of Chen Yongqiang was the same as the DNA information of the bloodstains found in Li Xiaomin's house. Does that mean that the other party was also killed? (End of this chapter)
