Why does Du Da Yong keep drawing pictures? That's because he also has to keep clearing up doubts for himself, which parts make sense and which parts don't make sense. These intersecting clues and information sometimes seem inconspicuous.
But most of the truth is actually buried in it.
The criminal suspect frequently showed himself in Xiajin County. Either he was very familiar with this place, or at least not unfamiliar with it. This was Du Dayong's first feeling after finishing the drawing.
But this should be the place where Cui Erquan settled back then, so Wang Hejun and his children will definitely not stay here for a long time. It is more likely that they have investigated or lingered here.
The place proposed by Fu Cheng and Ning Hewei expanded the scope, going down the river from Jing County or Wuqiao County, so there must be one of them, and Wang Hejun must have learned the skills of driving a boat.
So how did you learn this skill of driving a boat? This map is the same as that of Wang Anhu, because the Wang Anhu family all dealt with boats. According to Wang Hejun’s level of knowledge and education at that time, Du Dayong thought that Wang Hejun
I should have studied this thing at that time.
Moreover, Wang Hejun's legs and feet are not good, so he is not suitable for heavy physical life on land, so the possibility of choosing to live on a boat with water as his neighbor is very high.
The three children have grown up. If they really work and live on a boat, they will definitely be very familiar with the places nearby. If Cui Erquan started doing business, would he use boats when selling pickled vegetables?
Du Dayong kept this illustration and thought through it carefully. Judging from the geographical location, Du Dayong thought it was very possible.
The most important point is that what Fu Cheng and Ning Hewei said is very correct. The three children brought out by Wang Hejun must still be in Deshi or Wucheng County. Du Dayong believes that as long as he finds out where Wang Hejun ended up, he can follow these three children.
The traces of the growth of individual children can definitely be found out from these three children. As long as they are dug out, the corresponding traces will definitely be found.
Du Dayong thought for a while, and finally drove his car and began to search slowly along the river.
After the team members reunited at night, no new clues emerged.
Because this kind of large-scale investigation work actually requires a lot of police resources, and the scope of such investigation promotion is also very small.
But there is no need to worry, Du Da. The case has reached this stage, the investigation ideas have been finalized, and all the clues have been figured out. It just takes time.
On the third day, Zhao Youyan, one of the three policewomen, was the first to figure out the situation. The location she found was in Yangpu County, Yangpu City, Nanhe Province, where the owner of Yongsheng Pig Farm recognized Zhang Facai.
, and Zhang Facai often used to slaughter pigs here, but after he stopped doing this, in the first half of this year, he went to this boss and bought 12 bottles of animal anesthetic. Because he was an acquaintance, Zhang Facai had a good relationship with him before, so the pig farm
The boss didn't care, so he gave Zhang Facai a box of animal anesthetics half-sold and half-free.
After the animal anesthetic of the same brand was brought back, the Evidence Identification Center identified it as the same animal anesthetic found in the bodies of the four victims.
After questioning the owner of the pig farm, it was found that Zhang Facai came alone at that time, but he was not seen taking any transportation.
Zhang Facai's clues here were completely lost.
As for what means of transportation to check, Du Dayong would not consider it at all. Even if there is a national highway here, even if there is a toll station, it is useless. Some cars often take detours in the villages around the national highway, let alone such carefully planned criminal suspects.
People will no longer pay attention to things like monitoring.
Fu Cheng and Ning Hewei found no trace of Wang Hejun and his three children in Jing County and Wuqiao County. They also found no trace of Wang Hejun and his three children in Tang Shuaishuai. This was even a matter of fact.
After checking the results for three days, Du Dayong was a little confused. ωωw..net
Du Dayong firmly refused to believe that these people could disappear from this place out of thin air.
During the meeting on the third night, after Du Dayong drew a picture on the whiteboard, he started pointing to Xiajin County, Yangpu County and Wucheng County.
"Judging from what Zhao Youyan found out, Zhang Facai went to Yangpu County in mid-March this year to get the twelve anesthetics. So the date of Zhang Facai and the date of Zhang Facai's murder were actually several months apart, which shows that at this time
The suspect had already obtained the anesthetic, and then Zhang Facai continued to go out to flirt with women or wander around. There was a clear trajectory. But have you noticed a very strange phenomenon? "
The team members were immediately confused by Du Dayong's question.
Fu Cheng raised his hand at this time.
"Captain Du, Zhang Facai is very familiar with the criminal suspect, and there is no fortified place at all, and he is always on call. Judging from the time when Zhang Facai disappeared, we think it is normal, but
Now it seems very abrupt and very hasty, but this situation still did not make Zhang Facai notice anything strange or abnormal."
Du Dayong suddenly had a smile on his face.
(Two chapters tonight, the rest will be posted at noon tomorrow. Good night to all beauties.)
