As soon as Qin Gang searched, Shen Zhibin's phone number came out in seconds.

"There really is, the latest date is two days ago, there was no contact yesterday and the day before yesterday, it should be the day Zhang Jiajun came out, the call was very short, I think the two of them made an appointment to meet. The earliest time was about 4 months ago, not counting the most recent one, there were three calls this month, and the notification time was relatively short, none of them exceeded 30 seconds. Qin Gang said.

"What kind of friendship are they?" Xiaowei Road.

"At present, I am a mystery, and Shen Zhibin didn't tell us about the 300,000 yuan of funding, he deliberately concealed it?"

"Found it, found it." Qin Gang screamed excitedly.

Li Yi and Qin Gang both leaned over, and Qin Gang pointed to the picture of a knife on the monitor screen, "Eagle Claw Knife." ”

Li Yi took a closer look, the tip of the knife is very sharp, the material of the blade is tungsten steel, about 10 to 15 degrees of arc, and the tail of the knife has a little finger buckle ring for holding the knife, which is non-slip. ACCORDING TO THE INFORMATION IN THE PICTURE, IT IS 19MM LONG, 85MM LONG, 35MM WIDE, AND HAS A SHARP PROTRUSION ON THE TAIL, WHICH CAN BE USED TO ESCAPE BY HITTING GLASS.

"It's only about 10 centimeters when folded, and you can stuff any pants pocket into it, and use this guy to wipe your neck, one by one." Xiaowei Road.

Easy to carry, small, tungsten black, you may not be able to see it if you are not careful when you hold the ground at night, the tip of the knife pierces in, hooks the neck and pulls hard, Li Yi made up the scene in his head.

"If this murderer really used this knife, his understanding of the knife and the structure of the human body is still very clear, and he is quite professional, but this profession is used in the wrong place."

"How did you come up with a talon knife?" Qin Gang said.

"We have all seen the corpse, and the wounds on the neck, which are about 7 or 8 centimeters long, have a depth of 0.5 centimeters, which is very even. The human neck is round, and if you cut a cucumber with an ordinary straight knife, you cut it down with one knife, cutting into the shallow on both sides and deep in the middle, right? You can turn the cucumber, but the murderer can't turn Zhang Jiajun's neck, this shape of the knife is just right. There is only meat and blood vessels in the neck, and such a sharp knife, one stab and one pull, is not difficult. ”

"Professionally, you are a master of using knives."

"The wound is on the right side, the murderer should be behind Zhang Jiajun, I estimate it will only take a second to complete this action." Li Yi continued.

"Why behind?"

"There was also a hazy moonlight last night, and when you stretch out your hand face to face, people will always have a conditioned reflex, and the depth of the wound is different from the beginning to the end, and the deepest point of focus must be the piercing, which is located in the front of the neck."

Based on the wound and the fact that there were no traces of struggle at the scene, Li Yi determined that Zhang Jiajun was completely defenseless, and if there were more than two people at the scene, he might not know who gave him the knife.

"Since this knife is a tool that can be bought on the Internet, it is no fun to start with the murder weapon."

Xiao Wei shook his head and turned to sit down.

"What about the video, we haven't watched it yet, but the video is only in front of the brewery, there are still people walking and running at night on the embankment in this section, and the lights are black and black in this section of the brewery, and most people will not go over, and it is likely to eat a whiteboard, but we can definitely see Zhang Jiajun walking over." Qin Gang said.

"You have to look at the whiteboard, at present, I have to analyze what Zhang Jiajun wants to do when he goes to the old site of the brewery at night, he only brings a new mobile phone when he goes out, and there are more than ten yuan of cash in his wallet, mobile phone?"

Li Yi suddenly had an idea, the mobile phone was not Zhang Jiajun's, and the mobile phone might be the handle that Zhang Jiajun got.

"The mobile phone is not Zhang Jiajun's, when did he start using this new mobile phone, and what did Zhang Jiajun's family say."

"His wife also accidentally saw that he had a new mobile phone, and asked casually, Zhang Jiajun said that he borrowed it from a friend for a few days, and didn't ask anything else."

"We have to check the trajectory of Zhang Jiajun's movements in the past two days after he came out, when he goes out every day, the family may not know where he will go, so start from the monitoring near his house, follow the monitoring, we have to find out who he has seen in the past two days, in addition to Shen Zhibin, the most important thing is that he got the mobile phone before or after seeing Shen Zhibin, and this Xiaowei has to ask Zhang Jiajun's family again."

Xiaowei nodded.

"Fainted, or video." Qin Gang got up from his chair and pulled the whiteboard over.

"Brother Bin, come, take a look, we have to meet Shen Zhibin again."

Li Yi didn't plan to use the whiteboard, some information still needs to be synthesized first, at least, he himself feels that he hasn't figured out one, two, three for the time being.

"Have you checked the bank card in Zhang Jiajun's wallet?" Li Yi said.

"I checked, three cards, her wife knew the password, so she used Zhang Jiajun's mobile banking to check, at most there was a balance of more than 200 in one card, which can be said to be penniless." Xiaowei Road.

That's right, Zhang Jiajun wants to buy a shop, and the negotiated price is 900,000, he paid a deposit of 100,000, and there is a gap of 800,000, where does this come from. The deposit of 100,000 yuan is not at home, there is no source, he has an extra mobile phone in his hand for no reason, and the value of this mobile phone may be this money. ”

"Then if he agrees with the murderer to return his mobile phone at the brewery, and he doesn't bring his mobile phone, and he only has a dozen yuan in his wallet, which is not enough for him to take a taxi home, it is difficult for him to want to walk home." Xiao Wei asked.

"The mobile phone is related to money, he should take the money at the brewery, so it doesn't matter if he has money on him or not, the important thing is that he receives the money at the brewery."

"He received the fatal blow." Qin Gang said.

Li Yi picked up a whiteboard marker and wrote: brewery, mobile phone, money, murderer.

"Let's see if we can connect that way."

Qin Gang and Xiao Wei looked up at the whiteboard, "It seems like that, but there is one thing, if the murderer has been contacting Zhang Jiajun through this mobile phone, we will also be blind, and Zhang Jiajun's old mobile phone will not have any traces related to this." Qin Gang said.

"That's right, the 100,000 deposit was also paid to Zhang Jiajun by the murderer, and the specific amount agreed between them is unknown, my analysis is definitely not more than 900,000, the amount will be even larger, which may be the reason why the murderer will die. The reason why Zhang Jiajun went to see the shop and wanted to buy it must be that he thought that he would have a huge amount of money in his hands, otherwise Shen Zhibin's 300,000 yuan alone was far from enough, the money and mobile phone were only obtained in the past two days, and the murderer gave him 100,000 yuan first to stabilize him, but the murderer's mind was also meticulous, as long as the two people contacted, the police would definitely be able to find out, if the mobile phone did not belong to Zhang Jiajun, he could be invisible. ”

"It feels the same as the thoroughness of the accomplice we are looking for in the Lushan Yijing case, are the current criminals so aware of anti-reconnaissance and are advancing with the times?"

Xiao Wei blinked, "Maybe it's the same person." He burst out laughing.

"Don't cross the line, don't talk nonsense." Qin Gang said.

"Check Shen Zhibin, several operators have to check, see if he has opened a new account in the past two days, and the employees in his company should also check, don't forget that he also has two relatives at home in the second-hand car shop, these young people have little social experience, and they are easy to be used."

Li Yi looked at the time on his phone, "I contacted Shen Zhibin, I should still have time to go to his store, there is a lot of video content, you and Xiaowei filter together, wait for me to come back." ”
