Lin Chengzhen grabbed him, "Don't worry, the kidnappers are very cautious, maybe they will be squatting at the window of which corridor to look down." ”

Cheng Yue had no choice but to give up.

After a while, the information of the head of the household came out, saying that the west end of the third floor had been rented out for a month, and the identity information was verified to be false, but the tenant was a woman.

Cheng Yue was excited, which showed that the kidnappers should be a man and a woman, or even a couple, so that the difficulty of closing the net would be greatly reduced.

And the investigation of water, gas, garbage and other aspects also confirmed this, the water consumption is not large, it should be barely enough for two people to wash normally, the natural gas is almost zero, and the kidnapper's diet in the garbage bag proves to be solved by takeaway, and the takeaway is exactly three servings.

"Take all the contents of the garbage bag to the Physical Evidence Division, if Xie Tianqi's DNA can be tested, this kidnapping case will basically be clear." Lin Chengzhen said.

Everyone took action immediately, the garbage bags were expedited for inspection, and the number of vehicles around the old dilapidated community also increased faintly, and many fresh faces sneaked into the residential buildings around the second unit in casual clothes.

And after doing this, Lin Chengzhen, who had not rested, couldn't help but fight, so he leaned back on the car seat and fell asleep.

Cheng Yue's eyes were also bloodshot, but he was very excited, he couldn't help but look at Lin Chengzhen a few more times, and secretly sighed in his heart that he was ashamed, some people are born to do criminal investigation.

Lin Chengzhen slept until midnight, and it wasn't until Cheng Yue's mobile phone rang that he opened his eyes in a daze.

The Physical Evidence Laboratory Department found part of the oral mucosal tissue from a pair of chopsticks in the garbage bag, which was identified by DNA as belonging to Xie Tianqi.

The city bureau quickly formulated an arrest plan, and according to Lin Chengzhen's previous proposal, the arresting personnel were divided into three groups, one group was led by Lao Sui, the deputy head of the criminal police, who was responsible for arresting and rescuing hostages in residential buildings.

One group was led by Cheng Yue, and because the kidnappers may have explosives or other lethal weapons, in line with the principle of keeping as much alive as possible, the police will arrest both parties when they pay the ransom.

The last group, led by Deputy Director Zhao Cheng, arranged to set up an ambush at any possible trading location at any time.

At Cheng Yue's strong request, Lin Chengzhen was in a group with himself.

The next day, black clouds overwhelmed the city.

Such cloudy weather seems to be a good match for crime, and in the Weimin community, the residents who come and go around are not aware that they are already surrounded by a pair of vigilant eyes.

On the roof of the building opposite the second unit, several high-powered binoculars hiding behind the curtain were aimed at the west end of the third floor, waiting quietly.

Suddenly, someone on the walkie-talkie whispered, "Come out!" ”

Everyone was in good spirits, Cheng Yue and Lin Chengzhen fastened their seat belts respectively, and the clothing characteristics of the male kidnappers were reported on the walkie-talkie.

Half a minute later, a black deck Volkswagen of Han A-QBZ95 drove away from the community, and not far behind it, an inconspicuous silver Hyundai quietly followed.

A big net of round-up was slowly unwound without moving.

"The kidnapper just called Xie Junhao, and the other party asked him to rush to Wuyi Square within half an hour." Cheng Yue finished answering a phone call and frowned, "But the direction of the kidnappers is diametrically opposite to Wuyi Square, shall we continue to follow or go to Wuyi Square?" ”

Lin Chengzhen nodded, and said categorically: "Continue to follow." ”

After a little analysis, he speculated: "Wuyi Square is definitely not the final trading location, judging from the kidnapper's caution, whether Xie Junhao called the police or not, he is ready." He wanted to go around in circles with the police, to distract everyone from the police, and five suitcases of cash could prove that. ”
