Liu Pengcheng didn't expect such a result, but he recalled the relevant content he had learned in high school, as if there were indeed no human cells in sweat. When he was reminiscing, Wu Lingling spoke again: "Why don't you speak, are you in trouble?" ”

Liu Pengcheng said: "I'm not just in trouble, I'm just a ghost, I know who did it, but there is no evidence." ”

Wu Lingling said: "Then what do you have at hand, you can tell me, maybe I can come up with a way?" ”

Liu Pengcheng said angrily: "Just one glove, the murderer wore this white labor protection glove and killed ten people with a big dagger?" ”

Wu Lingling exclaimed on the phone: "Killed ten people? Wearing a glove? ”

Liu Pengcheng said: "Yes, it's this glove." ”

Wu Lingling said: "Look, you have to speak completely, how do you know that I have no way if you don't make it clear?" I know the kind of white labor protection gloves you said, they are relatively rough, he still holds a dagger, and he also kills, so this glove and the hands of criminals produce continuous, high-intensity friction for a long time, it is not just a matter of sweat, dead skin, and even living skin, sweat hair is very likely to be in this glove, but there are not many people in China who can do this level of extraction. ”

Liu Pengcheng hurriedly asked, "What about you, can you complete this extraction?" ”

Wu Lingling smiled and said, "I can, but I'm not sure, my teacher must be able to." ”

Liu Pengcheng said: "Okay, I'll ask the forensic doctor from the Qingbin City Bureau to find you today, no?" ”

Wu Lingling said: "Then call that Lin Ming over, he is still very diligent in running errands, unlike the forensic doctors in some places, he will not be able to drag anything and be the same as 258,000." ”

Liu Pengcheng said: "Okay, then I'll trouble you." With that, he hung up.

Wu Lingling listened to the busy tone on the phone, wrinkled her nose, and whispered into the phone: "Stinky bird, stupid bird, stupid bird, stupid bird, hum!" ”

After calling Wu Lingling, Liu Pengcheng hurriedly went directly to Lao Zhou, and told Lao Zhou about the content of the conversation with Wu Lingling, Lao Zhou said: "I will arrange it immediately, if DNA can be extracted from the glove, then this eucalyptus will break the deadlock." ”

Three hours later, Lin Ming took the collected samples of Zou Xiao and Cai Beikun, as well as a sealed glove, and flew to Shencheng on a flight.

And the survey around the victim has also begun to have feedback.

The eldest of the Hong family works in the financial department of the third hospital in Qingnan, her marriage is very happy, and his husband has recently been promoted, because the heating work has been done well for many years, and the citizen's home is very warm, and the director of the heating office may soon be promoted to the deputy director of the construction appointment, and he will also move forward one place to become the leader of the city heating office.

The heating office looks inconspicuous, but it is a very good unit, because this unit, like the nursing home, has a rest period, and it is busy for a few months of heating every year, and the rest of the time is basically in a state of semi-vacation, and the grassroots cadres and workers are even paid leave for a few months a year.

That's not all, the heating office also has the power to purchase a large amount of coal every year, and the development of new communities and buildings must also find the heating office first. It can be said that the director of the heating office is one of the more powerful officials in a city, and he is not conspicuous, and it is a low-key and affordable position.

The eldest sister's children are also very good, when they took the junior high school entrance examination, they were not admitted to the key high school in Qingbin City, and they were admitted to Qingnan No. 1 High School.

But this kid had to say that everything was the best arrangement, and went directly to Qingnan No. 1 Middle School, which he was admitted to, and is now the class leader of the key science class, and his academic performance is naturally among the best. The school also cultivated him as a seedling of a key university.

The family of the second eldest of the Hong family is also good, she is also the only one in the Hong family who is in business, and in the best junior high school in Qingnan, Qingnan No. 4 Middle School opened a large-scale stationery store.

Her husband's family is an educational family, his husband's grandfather opened the first modern middle school in Qingnan County, and his father has also been a teacher for life.

The information obtained by the Public Security Bureau is that his husband is a geography teacher, which is actually inaccurate, or incomplete, and he is indeed a geography teacher at Qingnan No. 4 Middle School, but he is still the director of the Academic Affairs Office.

His children are not like his cousin, they are more naughty, but after graduating from elementary school, they also entered Qingnan No. 4 Middle School, and they can't jump up under their father's nose. Although the two often quarrel a few words because of their children's education, the main reason is that the second child of the Hong family dotes on the children, but in general, this is also a happy family.

The situation of the third child of the Hong family is relatively difficult to grasp, because they lived with the old man Hong for a long time after marriage. There are no neighbors in their big yard, and there is no one in Zou Xiao's house, so the situation cannot be controlled at all.

Fortunately, after their children reached the age of going to school, they moved out of the big yard, the first is because it is convenient for children to go to school, and more importantly, the statement that Zou Xiao is the son-in-law of the old Hong family actually reached the ears of the old man, which is not a good word.

Hong Laosan is Hong Jiao, she is working in the personnel department of the Municipal Highway Management Office, the police went to her unit to ask, knowing that she is a very cheerful person, and helpful, and the popularity in the unit is very good, but basically not in the unit to talk about family affairs, everyone knows that her children are in the experimental primary school, her husband is an athlete, and nothing else is basically unknown.

So the police went to her house again and visited the neighbors, and the neighbors reported that there was nothing special, there was basically no movement in their house, and sometimes it was normal to quarrel a few words occasionally, how could there be a husband and wife who did not quarrel, and the number of times the neighbors heard their quarrels can be said to be very rare.

The police's investigation of Hong Jiao and Zou Xiao's family situation reached an impasse again, and just when Liu Pengcheng wanted to find two amiable policewomen to talk to their ten-year-old son, Lin Ming and Wu Lingling had a movement. UU reads books

It is not easy to say that this is also very difficult, the No. 1 sample and the No. 2 sample brought by Zou Xiao completed the test very smoothly, but for the glove, Wu Lingling failed to extract a qualified sample after two extractions.

In the end, I really had no choice, so I still asked her teacher for help. Her teacher also performed two extractions before finding a very small piece of skin and successfully extracting DNA from it. After testing, this is the DNA of sample No. 1, that is to say, the one who killed someone wearing this glove that day was Zou Xiao!

Getting this result, the entire group was dumbfounded! Because of Liu Pengcheng's reconnaissance work, except for Lao Zhou, he basically has no intersection with others, and even many members of the special group thought that Liu Pengcheng slept in the hotel every day, waiting to rub their credit. is because of his relationship with Lao Zhou's classmates.

Lao Zhou took the faxed results and said to Liu Pengcheng: "The problem now is that the evidence conflicts with each other, what are you going to do?" ”

Liu Pengcheng said: "There are two ways now, the first way is, of course, to figure out how this Zou Xiao died, if this problem is not solved, this piece will not be able to be settled, and there is no final conclusion on Zou Xiao."

"The Sword Comes"

The second method is expedient, divide the eucalyptus into two, the first eucalyptus is the killing of the whole family of the old man Hong, and the second eucalyptus is the killing of Zou Xiao. Because now the evidence of Zou Xiao's murder is conclusive. The motivation is also clear. But there is no evidence that the person who killed Zou Xiao and the person who killed Old Man Hong's family are the same person, so they can directly separate the eucalyptus. ”

Lao Zhou said: "What do you want to do now?" What is needed? ”

Liu Pengcheng said: "I'll go back to the scene to see, I really don't believe it, this Zou Xiao has nothing left except for a piece of dander in his gloves!" ”
