Qin Hong's lesson lasted for dozens of minutes, making the atmosphere in the classroom extremely lively.
From the change in the criminal's psychology to the infectious nature, and then from the case itself to the theoretical knowledge in the criminal investigation class, many students had a great understanding in this class.
Although Su Yang had never listened to Cheng Yi's lecture, from today's lesson, his mother's teaching ability should be better than Cheng Yi's.
After all, Cheng Yi had his own side business. Once the number of side jobs increased, it was naturally impossible to take care of more.
The class lasted for dozens of minutes. When the bell rang, Qin Hong left with her books.
Su Yang recorded some of Qin Hong's explanations in his notebook. Although he understood all of these contents, each person had their own way of thinking. Although Qin Hong was a theoretical expert in the criminal investigation world, when he encountered trouble without a basic theory, sometimes he needed to work twice as hard to think more thoroughly.
Su Yang took down all the notes and started a new class. However, it was cultural studies class next. Su Yang was a little bored, so he picked up his phone and chatted with Jiang Rou.
After chatting for one class after another, the morning passed in the blink of an eye.
There were no serious classes in the afternoon. Most of them were outdoor fitness programs.
For the entire day, Su Yang did not think about any case. He was enjoying his student life.
However, at night, Su Yang entered the group and tagged all the members.
"Did you guys find any clues about the case?”
A day had passed for Su Yang. To the members of the group, almost a month had passed.
Of course, during this month, the members of the group naturally had their own things to do. It was impossible for them to be completely immersed in that case.
Guan Hongfeng was the first to come out. He replied,"The case file is very detailed. All the procedures that need to be recorded in the murder case are recorded in detail. The case file itself had always been a signal that the murderer did not hide deeply, but he could not think of who it could be.”
"Something is missing, right? However, he couldn't figure out what was missing.”Fang Mu came out as well.
"Where's Qin Feng? What do you think of this case? Also, Mr. Qin, you are an expert in the autopsy report. Why don't you help us analyze it?”Guan Hongfeng asked.
When Qin Ming saw that he was being called, he also said,""I've read the autopsy report and the photos at the scene carefully. To be honest, I feel the same as you. There was no mistake in the autopsy. Even the calculation of the nail holes on the third victim was correct. However, one thing was for sure. The murderer would never leave his tools at the scene, and he would clean up the place after every crime.”
"Oh? How many nails are there?" Fang Mu asked.
Qin Ming smiled," Very interesting. There was also a seal on the body of the dead man. The number 2014726 was hidden on the seal." I know it's time, but the nail marks on the murderer's body are also 726! By the third case, the murderer's killing skills had already begun to mature!”
"There were 726 nail marks on the murderer's body, and the day of his death was also July 26th. This was the third case, and the murderer had already committed the crime. Then, the fourth and fifth cases should have something in common.”Fang Mu followed.
"The fourth victim died on August 18th. He was castrated. However, that place was cut off with only one knife, and then blood flowed freely. The murderer had tied him up, and his lower body was hanging in the air. There was also a basin of blood below. From the scene, there are basically no characteristics that match this date, but after studying it for a few days, hehe…I found the key data of 18!”
"Where?" Fang Mu and Guan Hongfeng asked hurriedly.”
"Look at the direction where the organ was thrown.”Qin Ming asked.
Fang Mu and Guan Hongfeng immediately went to look at the photos of the scene. After looking at them, they said,"If the victim is the center of the circle, then it's in the six o'clock direction!”
"When did the victim die?”
"The forensic doctor gave the time of death at around eight in the morning.”
"Yes, eight o'clock in the morning, but the organs are placed in the six o'clock direction. The victim was reported missing at six o'clock in the evening, which was eighteen o'clock.”
As Qin Ming spoke, everyone came to a realization,""So that's how it is! What about the fifth victim? Her time of death was December 27th!”
"Yes, the time of death of the fifth victim was December 27th. 27 means that there is no way to use time to match the coincidence of the date he requested. However, the murderer's methods of committing crimes were indeed becoming more and more mature. Or rather, he was already a highly intelligent criminal. Moreover, everyone should know what the ancient claustrophobic torture was. It was to use gravity to knock a woman's uterus off!”
"From the victim's abdomen, it is obvious that she was hit many times by something like a hammer. If nothing goes wrong, it should be 27 times! It was possible that the uterus had already fallen off, or it could have just happened to fall off, and then the murderer killed the victim! As for 12, the building had a total of 12 floors. However, the murderer did not kill the victims on the top floor. He had already begun to realize his hobby when he killed people and began to slowly hide it! Moreover, combined with the appearance of the five victims when they died, it could be seen that as time passed, the appearance of the victims became more and more dignified!”
" The first one was poisoned to the point of contorting his face. The second one drowned and became swollen beyond recognition. The third one was filled with nail holes. The fourth victim only lacked an external organ. The most recent victim lacked an internal organ!”
"He started to kill more and more meticulously, and more and more cruelly. This person had experienced a lot over the years!”
After Qing Ming finished speaking, he didn't say anything else. Fang Mu carefully looked at Qin Ming's analysis, and a picture gradually appeared in his mind.
He seemed to be a very ordinary person who was slowly becoming more successful and gentlemanly.
He began to put on a suit and a tie that made him look even more elegant. He also slowly put on a pair of shiny leather shoes.
His methods of killing became more and more particular, and his thoughts became more and more meticulous.
In the past ten years, the police's crime solving skills had improved, and the murderer had also become stronger.
Fang Mu used a pencil to describe the figure that appeared in his mind. Then, he sent it to the group and said solemnly,
"Through Dr. Qin's description and my own analysis of the clues, I made a suspicious portrait of the murderer.”
