"Team Ling, all the personnel with technical lockpicking skills that can be found are here." Qi Zhibin pointed to the three lists in his hand and said to Ling Zhan: "The six people in this one have a criminal record, and the twenty-eight people in this one have been reported to the public security organs. In the end, these 17 people were provided by various locksmithing companies in the city and provided a list of people who had not yet been reported. ”

Ling Zhan took it and took a closer look, and saw that each person was marked with three numbers: age, height, and weight. Moreover, those who meet the age group of 35 to 45 years old, Qi Zhibin has drawn them out with a red pen.

"Team Ling, there are eleven people of all ages. It's just that among these eleven people, there is no one whose height and weight match Uncle Xun's judgment. ”

Ling Zhan can also understand this, there must be more than 51 people in this list who know how to unlock locks in the entire general urban area, and there must be no statistics. It's just that the people who missed it are already difficult to find.

"Team Ling, is there such a possibility......."

"What?" Rubbing his temples, he raised his head from the three lists and looked at Qi Zhibin, who wanted to speak and stopped, Ling Zhan encouraged: "If you have any ideas, just speak up." ”

"Although I haven't been to the scene, I know from Uncle Xun's introduction that the abrupt barefoot bloody footprints look extremely abnormal."

Ling Zhan nodded, listening to Qi Zhibin continue: "Why did the suspect leave such a footprint, and only one? ”

"What do you think ......?"

"Could it be the ecstasy set up by the suspect for us?"

Hearing this, Ling Zhan's heart moved, and he encouraged Qi Zhibin again: "Go on." ”

"It is no secret that the method of estimating height and body shape based on footprints is that the folk proverb 'standing seven and sitting five pans three' (that is, the relationship between a person's height and the length of the soles of the feet is that the height of the feet is seven times the height of the soles of the feet when standing, the height of the soles of the feet when sitting on the ground is five times the height of the soles of the feet, and the distance between the knees when sitting cross-legged is three times the length of the soles of the feet), and the data inferred from this are generally consistent with normal people.

If, I mean if. If the suspect took advantage of this and prepared a paw-like model in advance, and deliberately left such a bloody footprint after committing the crime to mislead us, would it be explainable? ”

Looking at Qi Zhibin standing in front of him in a daze for four or five seconds, Ling Zhan suddenly grabbed the phone next to him and called Xun Jianguo, who was in the video group, down.

When Xun Jianguo came back and listened to Qi Zhibin's hypothesis, he was also stunned for a while before saying: "This possibility cannot be ruled out." ”

He bowed his head in the office and pondered for a while, and then said: "This possibility is very large, and only this explanation can explain the strangeness of the barefoot bloody footprints that suddenly appeared on the scene. Or the brains of young people are easy to use. It's just that where did the suspect get such a realistic footprint model? ”

"Uncle Xun, Team Ling, now that technology is so advanced, even a simulated human skin mask can be made vividly, let alone a footprint model?"

"Makes sense." Ling Zhan said excitedly: "I will order the criminal police team to investigate all the factories and workshops in the city that can manufacture simulation models. ”

Soon, Yue Xiangqi, the captain of the criminal police team, was called over by Ling Zhan, immediately gave him an order, and said to Qi Zhibin: "Xiao Qi, you also go and assist Captain Yue in his investigation." ”

"Yes."

After Qi Zhibin followed Yue Xiangqi away, Xun Jianguo smiled bitterly and said, "Hehe, I'm really old." I am always accustomed to thinking about problems in a conventional way, and I can't keep up with the development of the situation. ”

"Uncle Xun don't say that. Although young people are more open-minded, when it comes to actual combat experience, where is Uncle Xun's opponent. The topic changed and said: "For example, in this case, even if the suspect really used a simulation model, he can still analyze clues from it." ”

"You mean ......." Xun Jianguo looked at Ling Zhan and pondered for a moment and said, "Even if you use the simulation model, it is very likely that the gravity added to it still comes from the weight of the suspect?" ”

Ling Zhan nodded and said, "Otherwise, how could it be possible to use other heavy objects to leave such a clear footprint that can be imprinted with a fake footprint?" ”

"Makes sense." Xun Jianguo paced slowly in the office while analyzing: "First of all, it is certain that the actual length of the suspect's feet is smaller than the bloody footprints left on the ground. In other words, his actual height and weight are different from the previous results.

Secondly, the age reflected from the bloody footprints should not be fake, and the suspect should be around forty years old. Even if the suspect tries to create an illusion at this point, the sole of the foot can only exert force on one of the inner and outer sides, and cannot concentrate the force on the middle toe.

In addition, even if the suspect used a model of the sole of the foot, the minimum length of the foot would not be less than 22 cm. In this way, it is almost certain that it is male. ”

After analyzing this, Xun Jianguo stopped and looked at Ling Zhan and said, "No, I want to take a look at the scene again." ”

Ling Zhan knew what Xun Jianguo wanted to do, so he said casually: "Let's go together." ”

Of course, Xun Jianguo wanted to determine whether the suspect was holding other heavy objects in his arms in order to make the bloody footprints clearer and more confusing in order to make the bloody footprints clearer and more confusing. If there is, then the heavy object used by the suspect must still be left in the victim Lu Qingyuan's room. As long as the heavy object is found, combined with the clue that the suspect's foot length is actually smaller than the bloody footprint, the suspect's height, weight and other parameters can be roughly estimated.

After the two entered the door, they first looked around carefully, but found no furniture that had obviously been moved. For example, the small wooden coffee table in the living room, such as the TV set on the TV cabinet opposite. Although there are a lot of small appliances in the kitchen, the heaviest one is only the electric pressure cooker, which is only about ten catties at best, and the suspect should not use it to increase the weight.

In the end, it was Xun Jianguo who found an old rattan box that had been turned over on the lower level of Lu Qingyuan's bedroom closet, which was about 70 centimeters long, 40 centimeters wide, and about 30 centimeters thick. I took the messy old clothes inside and checked them in my hand, and I felt that the weight should be more than twenty pounds, less than twenty-five pounds.

"Could it be this box?"

"Other than that, there doesn't seem to be anything else."

"If the suspect really used this rattan box, then it should not weigh more than 120 pounds."

Carefully consider the bloody footprints on the ground again, because the edges around the footprints are relatively clear, that is to say, although the actual size of the suspect's foot is not as large as the bloody footprints, it is not much smaller. According to common sense, the simulated paw model prepared by the suspect in advance should not be too large, because it is neither economical nor convenient to carry. If it is similar to rubber gloves, the difference between the front and back should not exceed 0.5 to 1 cm.

In this way, the height of the suspect should be between 168 (24X7) and 171 (24.5X7) cm. The normal weight is 135 to 145 pounds, and if you subtract the weight of this rattan box, it is between 110 and 125 pounds.

According to the results of this speculation, Ling Zhan immediately compared three eligible people from the three lists with technical lockpicking skills that Qi Zhibin had listed before.

Yao Qiang, male, 38 years old, 168 cm tall and 62 kg in weight.

Xu Zhongliang, male, 41 years old, 170 cm tall and 55 kg in weight.

Xu Linchuan, male, 39 years old, 170 cm tall and 61 kg in weight.

Without hesitation, Ling Zhan first called the video team and informed them to find similar people from the video materials according to the suspect's body shape characteristics that they had just speculated.

Secondly, he called Rong Liang and Zhao Zengyuan, who were visiting outside, and Song Jin, who was looking for the source of the blue bath flower.

In the end, he and Xun Jianguo immediately went to the police station where the above three people were registered and began to conduct an external investigation on them.
