Zheng Wanjiang analyzed and reasoned about the case based on the current situation.

The murderer who killed him was taller than He Jinqiang, which can be seen from the strangulation marks on his neck, because the strangulation marks U are upward. The murderer's body is relatively strong, and the depth of the strangulation marks is deep, indicating that he has a certain strength, and his age should be similar to He Jinqiang's.

There are also those two letters to the He family, which also illustrates the problem. Judging from the tone of the letter, he is a man over forty years old, and this person is a character with extraordinary experience and brain.

"So, where do you think the first scene of the murder is?" Sun Yaozhang asked.

"If He Jingang is involved in this case, then it must be a familiar place for him, and it is also a place that He Jinqiang is familiar with, but there is no trace of his home and his dormitory, I judge that it should be somewhere around He Jingang, as for where it is, we will continue to investigate." Zheng Wanjiang said.

"That's right, I agree with you." Chu Mingxiang came in and said.

"The Reserve Board." Zheng Wanjiang and the others stood up.

It turned out that Chu Mingxiang had been standing at the door for a long time, and he had heard Zheng Wanjiang's conversation, so in order not to disturb their discussion of the case and affect his train of thought, he did not come in. He believes that his analysis is very reasonable, that he can objectively and realistically analyze the facts of the case, and that he can fully apply the scientific and theoretical knowledge he has learned to practical work.

At the same time, he felt that he was a little unsuitable for the development of the new situation, he had reached the age of leaving his post to rest, and he already had an idea about himself, and he was ready to resign from the post of director of the public security bureau, but he did not tell anyone clearly. So what does he think about the case?

He believes that He Jinqiang's case is a very complicated case, he has handled many cases, like this case is still rare, it is not easy to solve this case, Zheng Wanjiang and their work Chu Mingxiang is very satisfied, but Zheng Wanjiang They are still young and have little experience in handling cases, and they are a little uneasy, he saw that Zheng Wanjiang They are full of confidence in the investigation of the case, and have made a breakthrough in the investigation of the case, and found a lot of clues from it, especially after listening to Zheng Wanjiang's analysis of the case, it is exactly the same as his thoughts.

"Fed, what do you think we should do next? Could you please give us any specific instructions? Zheng Wanjiang looked at Chu Mingxiang with soliciting eyes.

"Aren't you all arranged? I don't have any opinion to do as you say, but be cautious, don't be emotional, murderers are very fierce and cunning, they will do whatever it takes to carry out sabotage activities in order to achieve their evil goals, which requires you to give full play to your wisdom and talents to compete with them, and firmly grasp the breakthrough of the case, so that the case can be solved as soon as possible, catch the murderer, maybe this is another big case, enough for you to do it for a while, so you must make the work ideas clear, think wider, Don't be confined to a small circle. Chu Mingxiang said.

"Please rest assured, criminals are cunning, and they cannot escape the people's justice."
