The video data was originally kept by the property company that cooperated with the school, and has now been handed over to the Security Office. Lao Wang was originally responsible for the management and maintenance of surveillance videos, and is now the person in charge of this aspect in the Security Office. He will lead
Chen Yu and others came to check the records.
"Chen Ke, Jin Ke, we checked last time and found no suspicious persons leaving with anything suspected to be lost." Lao Wang was very good at talking, so Chen Yu and Jin Xiaobai all called him "Chen Ke" and "Jin Ke".
It is easy to give people a sense of respect by using administrative titles such as "Section" as a respectful title.
Jin Xiaobai also shook his head and said: "There are only six cameras in the whole school, and there is only one in Caifeng Pavilion. It is indeed too few."
Chen Yu said: "Xiaobai, you and Lao Wang are checking the four school gates and Qinglong Tower, mainly checking several types of people: two days before the two crimes, the day and the next two days, whether there are strangers or people acting suspiciously."
Seeing that the two people had some doubts, he explained: "Although I am not a professional, I feel that the thief left no obvious traces and committed crimes continuously. He must be cautious and bold. He will definitely check out the spots in advance, and may not do so more than once."
Once, I will probably return to the scene afterwards to test the reaction.”
Both Jin Xiaobai and Jin Xiaobai nodded in agreement and went to check the video as he said.
Chen Yu himself began to check the video recordings of Caifeng Pavilion.
Viewing videos is undoubtedly a very boring thing. Watching some people appear and disappear mechanically from a fixed position, and it is a silent pantomime. Sometimes there is a sense of suffocation caused by lack of air, which makes people unconscious.
I want to take a rest.
Half an hour later, Jin Xiaobai and Lao Wang stopped and came over to see Chen Yu, who was still interested in inspecting it.
"Brother Yu, aren't you tired?" Jin Xiaobai said in admiration.
"No, actually watching these videos is an interesting thing." Chen Yu shook his head slightly, and seeing his disbelief, he continued, "You can see some interesting things from some details. For example, in the past half hour, I
At least two non-dormitory students came into Caifeng Pavilion."
"Impossible. The school stipulates that boys cannot enter Caifeng Pavilion. Only women are allowed in and out. Chen Ke, can you tell which student is not in the dormitory?" Lao Wang said a little doubtfully.
Chen Yu pointed at a petite girl in the picture and said, "Do you think this girl is from Caifeng Pavilion?"
Lao Wang often went to the security room of Caifeng Pavilion to help with management. He was very familiar with the girls in the building. He carefully identified them and said, "I haven't seen them before, so they shouldn't be. Chen Ke, how did you recognize them?"
Chen Yudao: "Actually, it's very easy. Students in general dormitories are more natural when passing by the door of the dormitory building, while students in non-dormitories are more nervous. The nervousness is manifested in many aspects, such as walking with stiff legs, not daring to look at the security room, and pretending
His eyes are wandering when talking on the phone, etc. Do you think this student has these characteristics?"
"Yes, Brother Yu is awesome!" Jin Xiaobai followed what Chen Yu said. Sure enough, the girl's eyes were wandering and she didn't dare to look towards the security room. She even took out a silver mobile phone from her clothes to cover it up.
With.
"This is a situation. Of course, some people have good psychological quality and do not show nervousness in their expressions, but if they can't even find the dormitory anywhere, they can be said to be foreign students." After Chen Yu finished speaking, he pointed.
Another short girl showed them to them.
Jin Xiaobai immediately looked at it carefully and suddenly said: "She passed back and forth from the camera three times!"
"Yes. How could a girl who lives in this building go in the wrong direction? She definitely doesn't live here." Chen Yu said with a smile.
"Brother Yu, then these two people may be suspects?" Jin Xiaobai said suddenly.
"No, it's unlikely to be these two people." Chen Yu shook his head and said, "This thief must be taller."
"Why?" Lao Wang asked curiously.
"Let me share my thoughts. They may not be correct, but they are just for reference." Chen Yu thought for a while and said, "Judging from the two cases in Caifeng Pavilion, the thief has flexible movements, slender fingers, and should weigh 100 kilograms."
above."
"Brother Yu, how did you see this?" Jin Xiaobai asked curiously.
"First of all, both cases were stolen when the locks of the dormitory doors were not broken, and I can tell from the traces on the doorknobs at the scene that the thieves may have used ribbons or other items to open the door, which requires nimble fingers.
Only then can we do it. In addition, if the thief can enter and exit through the escape passage, he must be more agile."
"Can I open the door with a ribbon?" Jin Xiaobai couldn't help asking as soon as Chen Yu finished speaking.
"Yes, if you practice properly, a rope can open the door of an ordinary car from the outside. Do you believe it? You can search for videos on the Internet and you will know. So, it is possible to open the door with a ribbon." Chen
Yu affirmed.
"Second, judging from the traces at the scene, the thief had slender fingers." After speaking, Chen Yu took out a photo, showing a faint fingerprint in the dust at the edge of the bed, and continued, "Although the thief had
The gloves left no fingerprints, but the outline of the hand did."
Lao Wang secretly nodded, feeling that he paid attention to the details very seriously. After all, he and the people from the police station didn't find anything when they looked at the scene last time. Although it was related to the lack of seriousness of the people at the police station, it also proved that the situation in front of him was
The boy's observation ability is as sharp as his thinking.
"Third, that day on the ground below the escape tunnel, I found a small pit with some silvery white plastic powder on it." As he said, Chen Yu took out another photo. Sure enough, there was a hole on the ground in the photo.
There is indeed a small round pit with a diameter of about 5 mm, and there are indeed some silvery things in it. If you are not careful, you can't find it at all.
Chen Yu continued: "Based on the height of the escape passage ladder from the ground, the hardness of the cement on the ground, and the stress-bearing area of the heel, etc., and using the formula of impulse acceleration, we can roughly calculate that the thief weighs about 100 kilograms."
The other two people were a little stunned. Jin Xiaobai even scratched his head and said, "Brother Yu, why didn't I think of so much?"
Chen Yu said with a smile: "These are some of my rough analysis and judgments, which may not be correct. I usually read more detective novels and film and television works, and think more about life. In fact, many people can do it, and it doesn't count. So based on the above opinions
"Girls must either be slightly fatter or taller to reach this weight. These two girls do not meet the requirements visually."
"Hey, then we can start looking for high heels and see if anyone wearing high heels comes in and out of the door during that time. However, many girls nowadays wear high heels, so it's not easy to find?"
Chen Yu didn't say anything, but he suddenly thought of Madonna's classic saying: The feeling of wearing manolo is better than sex, and it is absolutely long-lasting! Hnik, who would wear this brand's classic style? Wearing this level of "ceremony"
Is it possible to steal "car shoes"... Thinking of this, a beautiful face suddenly appeared in my mind...
Thinking of this, he suddenly had another idea, opened the school's forum section, and browsed with interest in the "Beautiful Picture Show", "Water Man Oscar" and "Oscar Top Ten" sections.
