The scene of the dumping of the body is not large, but the urine stain is not a blood stain, and it is difficult to make it visible through technical means.

More importantly, the victim not only wore pants, but also wore thick ones. The innermost part is the underwear, then the autumn pants, the autumn pants are a pair of warm pants on the outside, and there is a pair of slacks on the outside of the warm pants, and the suspect's hands may be stained with the deceased's incontinence when he transports the body to the river, but the deceased's feces and urine may not necessarily get on the ground and grass.

Yu Guosheng, Lao Kong, Xiao Chen, and other technical police officers of the Xiang Yaxin Organization carefully investigated the scene for many hours, but they still did not find any urine traces of the victims, so they could only use the most stupid method to "draw grids" at the scene, and take a sample from each grid.

The samples were sent to the forensic examination and identification center of the Municipal Bureau, and the police from the DNA laboratory really handled the special case.

The current equipment is very advanced, and it only takes an hour and a half to test and compare whether there is any victim DNA in more than 70 samples. Xiang Yaxin simply asked Yu Guosheng to go back to the sub-bureau first, and he sat in the hall of the inspection center to wait, while Feng Ju and Liu Jianye also sat in the conference room of the hotel where the task force was located and waited for his news.

Feng Ju picked up his mobile phone again to look at the time, and said in a deep voice: "I said how did you withdraw the people who touched the row, it turned out that Lao Gu, Lao Ji and Han Chaoyang took over, and they were targeted to touch the row." ”

Liu Jianye took a deep breath and said with a wry smile: "It's not that they withdrew the people because they took over, but they can't figure it out if they touch it again." ”

Feng Ju thought that the reason why Han Chaoyang and several old men were able to target the investigation was because they had narrowed the scope of the investigation to a very small size, and couldn't help muttering: "How did Xiang Yaxin, the squadron leader, do it, how did the scene investigate, and the grass on the edge of the septic tank was not found by anyone, which is also too careless." ”

"Feng Ju, this can't be completely blamed on them, it's that the attention at that time was all focused on the suspect's footprints, focusing on finding other items such as mobile phones. ”

"Fortunately, Ji Kaiyuan found out, if the grass was really the suspect, we didn't find such an important trace, which led to the delay in solving the case, who is responsible for this?" Feng Ju raised his head and changed his words again: "The cowhide is not blown, the train is not pushed, Ji Kaiyuan's fiery eyes are really worthy of his reputation, but I didn't expect him to retire for so many years and still have a treasure sword." ”

Speaking of this, Liu Jianye immediately came to his senses, and couldn't help laughing: "According to Xiao Wu of our office, Lao Wu's eyesight may be even better than Lao Ji." ”

"I believe that the reason why Wu Wenge's reputation back then was not as big as Lao Ji was mainly because he was not a police officer, in fact, he caught no fewer thieves than Lao Ji. And Lao Ji was lucky, one year the Ministry of Public Security organized anti-pickpocketing police in various provinces and cities to fight pickpocketing in different places, and he caught up and went to the East China Sea to catch thieves, which made a splash. ”

……

While we were chatting, my phone rang.

Liu Jianye glanced at the caller ID, and immediately connected it and raised it to his ear: "Yaxin, the result is out?"

"Liu, the test report has just come out, and none of the 82 samples have detected the victim's DNA. ”

"Got it. "I'm really afraid of something, Liu Jianye is cold in his heart.

Feng Ju heard it clearly, but he was also extremely disappointed, squinted at Liu Jianye, and took the words back to his mouth.

Liu Jianye was stunned for about two minutes before he came to his senses, hesitated for a moment and asked in a low voice, "Feng Ju, what should I do now?"

"You are more familiar with the case than I am, and you have been in command for the past few days, and you have made up your mind. ”

"I've been waiting for half a day, and I'll wait for more than ten hours. ”

Feng Ju didn't know what Liu Jianye was waiting for, and he didn't know what else he had to wait for, but considering that he was the general of Liu Ju's order, he took the bag and got up and said: "It's okay, it's dark anyway, and now I can't do anything else if I want to, I'll go back to the bureau first, and contact me in time if there is any news." ”

"Feng Ju, I'll send you. ”

"Don't send it. ”

……

Feng Ju walked downstairs with heavy steps, got into the police car and asked the driver to return to the precinct.

Not long after the car drove out of the hotel parking lot, he suddenly opened his eyes when he was leaning on a chair and closing his eyes: "Xiao Liu, don't go back to the sub-bureau first, go to Han Chaoyang first." ”

"Feng Ju, go to the Sixth Academy?"

"I'll call him first and ask where he is. ”

"Okay, it's not going to turn around here, I'll go ahead first. ”

Make a phone call and ask Han Chaoyang's location, Feng Ju asked the driver to go straight to the compound of the old district committee of Huayuan Street.

The driver came for the first time, Feng Bureau had not been here before, although it was very close to the East Long-distance Bus Station, but the old district committee compound was in the alley, it was not easy to find, and I had to open the navigation.

When I arrived at the compound of the old district party committee, I saw that the cafeteria and the conference room on the first floor were brightly lit.

The young men were watching TV and eating in the cafeteria, Han Chaoyang was sitting in the conference room answering the phone, with a laptop in front of him, and a laser printer next to the computer.

There were so many young men in the compound, and no one came to see the excitement.

The secrecy work was done well, Feng Ju was very satisfied, raised his arm and knocked on the open door, and pretended to smile easily: "Old Gu, Xiao Han, just you are here, what about the others?"

Grandpa Gu pouted, took off his reading glasses and got up to greet him: "Feng Ju is here, Feng Ju, have you eaten?"

"No, but I'm not hungry. ”

"If you don't eat it, we eat it here, and we don't eat either," Grandpa Gu asked Feng Ju to sit down, and explained with a smile: "Lao Ji, Lao Wu, Lao Ding and the boys of the anti-pickpocketing team are all outside to investigate, Lao Tang and Xiao Miao are investigating the outsiders who have rented near the fertilizer factory in the past three years at the Xinyuan Street Police Station, regardless of whether they are male or female, whether they are lame or not, as long as they find out that they meet the two characteristics of height and weight, all the people are gathered here to us, you see, so many have been found in one afternoon." ”

"That's a lot. Feng Ju picked up a stack of photos, and asked in a low voice while flipping through them, "Did you find anything suspicious?"

"There is no possible connection with the 3.14 case for the time being, but a fugitive has been identified. ”

"Who?"

"This. Grandpa Gu took out a photo and a printout of his ID card information from the folder on the left, handed them over and said with a smile: "Sheng Yan, a native of Jiangnan Province, is suspected of falsely issuing special VAT invoices and is wanted on the Internet, and has been hiding in Taoyuan New Village for more than a year, the house is rented by his concubine, and he himself has not been registered at the Xinyuan Street Police Station. ”

It's really a rabbit with grass, Feng Ju couldn't help but smile and asked, "Did you notify Bao Qingshan?"

"There is no need to notify," Grandpa Gu handed over a cigarette and explained: "The person was accidentally discovered by Lao Wu and Xiao Wang of the anti-pickpocketing team when they learned about the man with the physical characteristics of another symbol on the side of Taoyuan New Village, Lao Wu and Xiao Wang are not policemen, and they have no law enforcement powers, so it is not easy to go up for interrogation, confirm that he entered Room 506 of Building 4, and he stayed downstairs to call Lao Tang, and Lao Tang found it when he rushed over for interrogation." ”
