In Tian Surong's office, Ling Xu, Chen Shaochun, Mo Chengyun, father and daughter, all sat on the sofa below, Tian Surong sat on the office chair and looked at Mo Wanqing, and after a while, she looked at Chen Shaochun: "Captain Chen, you tell Ling Xu and Chairman Mo about the case, and let them know the reason why the criminal police team interrogated Mo Wanqing." ”

"Yes, Tian Bureau." In response, Chen Shaochun stood up and said with a serious expression: "At eight o'clock this morning, the sub-bureau received a police report from the school district police station, saying that a female corpse was found in the women's dormitory building of Yenching University.

The deceased was named Li Yanxin, a 20-year-old student from Moling City, Yunnan-Guizhou Province, and a student in Class 7 of the Department of Economics and Management.

According to Zhang Rongfen, when she was cleaning this morning, she smelled a faint smell of blood from the entrance of the corridor on the ninth floor.

Zhang Rongfen was puzzled, so she went upstairs to check, she followed the smell all the way to the No. 26 dormitory on the tenth floor, when she walked to the door, she found that the smell of blood was coming from the dormitory.

After discovering the abnormality, Zhang Rongfen did not dare to move, and hurriedly reported to the school leaders, after the school person in charge inquired, he went to the tenth floor to check the situation, and after confirming that the things reported by Zhang Rongfen were true, he immediately called the police.

After the police from the police station in the jurisdiction arrived at the scene, they wanted to open the door and enter the dormitory, but because the dormitory door was locked, the police found the dormitory administrator Du Guirong and wanted her to open the dormitory door.

But when Du Guirong came to the tenth floor and saw the building number of the dormitory, she told the police that she did not have the key to this dormitory, because half a year ago, a female student in dormitory No. 26 committed suicide by cutting her wrists in the dormitory.

Although the school later calmed down the matter, the students in the dormitory and even the entire students on the tenth floor felt panicked, after all, there was a dead person, and those female students felt embarrassed in their hearts, and they reacted to the school one after another, saying that they did not dare to live from the school.

Especially the students who were in the same dormitory as the girl, they were even more frightened and talked nonsense all day long, saying that when they went to bed at night, they saw the ghost of the dead girl, and not long after, those girls were all hospitalized in fright.

Considering the panic of the students and the fear of rumors that would be unfavorable to the school, the school vacated the entire dormitory on the tenth floor, arranged all the students in the dormitory downstairs, and took back the keys to all the dormitories on the tenth floor.

After listening to Du Guirong's account, the police had to ask the school to contact Li Ping, the teacher who manages the school's dormitory building, and asked Teacher Li to come and open the dormitory.

But it was not a coincidence, Mr. Li took leave to return to his hometown the day before, and the key was locked in the iron cabinet.

When the door of the dormitory was opened, I saw blood everywhere on the ground, and on a bed near the window on the left side of the dormitory, there was a female corpse.

After I led a team to the scene to understand the situation, we immediately sent technicians and forensic doctors to inspect the scene, and after confirming the identity of the deceased, we collected traces and evidence from the scene while inspecting the body.

The cause of death was a sharp weapon pierced into the abdomen, which caused internal organ damage and excessive blood loss, which eventually led to death, and there were two wounds, located three centimeters above the body's navel and five centimeters below the heart.

The murder weapon was left at the scene by the murderer, it was a 30-centimeter-long fruit knife, inserted into the wound under the deceased's heart, and the forensic preliminary identification showed that the time of death of the deceased was between 23 o'clock last night and 1 o'clock the next morning.

We extracted two hairs from the corpse, and at the same time, technicians extracted the murderer's fingerprints on the walls, dormitory switches, dormitory door handles, and door locks.

In addition to these, there are two most important pieces of evidence, that is, the fruit knife on the deceased's body, we also found Mo Wanqing's fingerprints from the position of the handle of the murder weapon, and another piece of evidence is Mo Wanqing's slipper soles.

After identifying Mo Wanqing as the suspect, we immediately went to the dormitory to check Mo Wanqing's belongings, and found a drop of blood on the sole of her shoe, which was found to be the blood on the deceased's body.

Just before you entered the interrogation room to rob someone, the results of the DNA comparison of the two hairs also came out, and after technical comparison, the two hairs found next to the deceased were Mo Wanqing's hair.

Ling Xu, you are also a policeman, and you have also participated in the investigation of the case, you can say it in your heart, if it were you, based on these clues in front of you, would you list Mo Wanqing as a suspect for interrogation? ”

Hearing this, Ling Xu was silent, Chen Shaochun was right, these discoveries in front of him were extremely bad for Mo Wanqing, if it was him, I am afraid that he would choose to interrogate Mo Wanqing like Chen Shaochun.

Although this is the truth, Ling Xu still refused to believe that Mo Wanqing would kill people, and after a moment of silence, he asked a question: "Captain Chen, I want to ask, why did you immediately lock Mo Wanqing after you extracted your hair and fingerprints at the scene?"

I mean there were a lot of people in that dorm building, and everybody was suspicious, what did you base your judgment on? Decide that Wanqing is the murderer? From the time you enter the site to the time you go to the classroom to take away the evening, this time is only about three hours.

In such a short time, you don't have time to compare fingerprints, it stands to reason that even if you find fingerprints, you should compare and verify them one by one until you find out the identity of the owner of the fingerprints, but you didn't do this, but went directly into the classroom to summon Wanqing, how do you know that those fingerprints are Wanqing's?

I don't doubt what you mean, I'm just puzzled, if I see a fingerprint at the scene, I can't determine whether the owner of the fingerprint is a man or a woman, let alone who the fingerprint belongs to, without comparing the fingerprints of the parties.

But without comparing Wanqing's fingerprints in advance, you quickly determined that the fingerprints belonged to Wanqing, and immediately listed Wanqing as a murderer, I don't know how you did it? ”

Hearing Ling Xu's question, Chen Shaochun was not annoyed, he glanced at Mo Wanqing, and explained in a soft tone: "The reason why I was able to make such a judgment was because of Mo Wanqing herself. She cleverly made up a story of a female ghost killing people in an attempt to confuse the public, but she didn't expect that it was this story that exposed her. ”

"Female ghost killing? What do you mean? Ling Xu's brows were twisted into the word "Chuan", with a layer of incomprehension and doubt on his face. (To be continued.) )
