This problem is very common, because when they go out of the car, most of them are one-way round-trips, that is to say, when they go or come back, they are empty, in order to make some extra money, find an empty car distribution company, by the way, pull some work, sometimes acquaintances will also find them, the freight price is negotiated, but it is much cheaper than hiring a car alone, because this is a matter of beating rabbits and piggybacking on feet, without spending their own money, giving more and less are in vain, customers in order to save money, it is common to send some cigarettes and alcohol, anyway, it is not their own car, as long as there is no accident, everything is easy to say. Some people also have regular customers, in a word, in order to save some freight, and the driver can also make some benefits.

So does He Jinqiang have any regular customers? Where are they from? This is a new issue that cannot be ignored. Zheng Wanjiang asked.

"They don't know this problem, it's all their own private work, who does it and no one will say, if you let the leader know, then you have to pay it back, you will definitely be criticized, He Jinqiang is a bachelor, he is a well-fed family and not hungry winners, he will not care about the price, especially acquaintances, it is impossible to ask for too much money, and now people know that they can't do it in vain when they find anyone, and send some cigarettes and alcohol to express their gratitude, which is also normal." Sun Yaozhang said.

After listening to Sun Yaozhang's words, Zheng Wanjiang nodded, He Jingang, Wang Daqing, and Li Qiulan have been brought into view, and He Jinqiang's case has some clues, which has made the case develop further deeply, Sun Yaozhang's words reminded him that some people will do anything for money, and they can't be deceived by superficial phenomena, and some things make him have to think more, but he can't be sure yet, because there is no conclusive evidence, and further investigation is still needed.

"Judging from He Jinqiang's diary, we only found one, and it was his most recent, we didn't find his previous diary, it is impossible for him to remember it on a whim, only for the past few days." Zheng Wanjiang said.

If so, indicating that there is something wrong with his diary, it will further complicate the case, then where is the previous diary? Try to find his previous diary. He Jingang is mentioned in the diary, this is an important clue, He Jinqiang's death is very likely to be related to him, and his situation should be investigated more intensively to find out his activities thoroughly.

"Don't worry, I'll figure it out and promise not to let you down." Sun Yaozhang said.

"Now we are going our separate ways, find relevant clues as soon as possible, speed up the speed of solving the case, time waits for no one, to prevent them from jumping over the wall to take action, our opponent is not a simple character, has a certain anti-investigation ability, and must not let them go ahead of us." Zheng Wanjiang said.

According to the current investigation, a number of suspicious points have been revealed, He Jinqiang's homicide case has been established, resulting in the complication of the case, some doubts are unbelievable, it seems that this is not an ordinary homicide case, its background is unpredictable, all factors must be taken into account, the special case team carefully analyzed the case, discussed the next work plan, some signs show that this is a murder case, but its motive is complex, like seeing flowers in the fog, hazy, people are difficult to determine for a while, and further investigation must be done to solve the mystery.

According to Zheng Wanjiang's work arrangement, Huang Limei and Yue Ziqing came to Li Qiulan's house, which is an ordinary small farm yard, with five main houses, three side rooms, a pigsty outside, and a few small sheds, the house was still built in the early eighties, compared with the tall houses in the neighborhoods on both sides, it seems a little low and simple, but the courtyard is extremely clean and neat.

Li Qiulan's father's name is Li Guofu, 51 years old this year, her mother's name is Wang Liu Chunping, 52 years old this year, the old couple are authentic farmers, contracting four acres of land responsibility in the village, her father usually goes out to do some odd jobs for the construction team to subsidize the family, Qiulan works in the Leifa binding factory, has an income of several hundred yuan a month, her mother raises 10 pigs and dozens of chickens at home, the family income is not rich, it belongs to the subsistence type in the countryside, and life seems to be extremely ordinary.
