Gao Huanyu frowned, feeling that something was wrong.
When they returned to the Dongcheng Police Station, the other police officers came to congratulate Liu Jun when they heard that the suitcase body case was solved so quickly.
Liu Jun was surrounded by the crowd and laughed so hard that he couldn't stop. He imitated Gao Huanyu's behavior just now and told everyone the process of the interrogation vividly.
Just at this time, the forensic doctor found new evidence during further autopsy and sent it to the two.
Liu Jun didn't take it seriously, but Gao Huanyu took the new evidence and examined it carefully - it was a white stationery knife.
After examination, the forensic doctor determined that the wounds on the body were caused by this stationery knife, which was initially stuck in the gap of the swollen body and was not discovered at the first time.
Gao Huanyu looked at the stationery knife which was less than half the length of his palm when folded and only a few millimeters thick and fell into deep thought.
If, as Qu Jingyun said, Qiao Yulan was strangled to death by Du Anping, then why did Du Anping use a stationery knife to cut her face and body so many times after strangling her?
If the purpose was to prevent the body from being identified, scratching the face would be enough. Why are there so many scars on the body?
Moreover, how could a vicious person like Du Anping use such a child-like-looking stationery knife as a murder weapon?
Gao Huanyu suddenly thought of something and looked up to call out to Liu Jun:
"Brother Liu, do you have Du Anping's file?"
Liu Jun was in a good mood at this time, and nodded with a smile:
"Yes, didn't the court say there wasn't enough evidence? Du Anping's file wasn't rushed into storage and is still with me!"
Gao Huanyu immediately said:
"Brother Liu, hurry up and show me Du Anping's file!"
Liu Jun heard the urgency in Gao Huanyu's words and didn't bother chatting with others. He quickly took out Du Anping's file from the cabinet and handed it to Gao Huanyu:
"Here! What's up? Any new discoveries?"
Gao Huanyu didn't say anything, his eyes quickly scanning back and forth on Du Anping's file. Suddenly, his eyes lit up and he pointed to a line of words on the file and said:
"I said there was something wrong with what Qu Jingyun said!"
"What's the problem?"
Liu Jun quickly leaned over to take a look, and saw that the line of words Gao Huanyu was pointing at said that Du Anping's estimated time of death was a week ago.
He pondered, a week before the report date...
"Damn it! How dare this Qu guy treat us like fools?!"
If Xiao Gao had not been careful enough to find Du Anping's file to confirm, he would have almost been deceived by the woman surnamed Qu.
Cheating him is a small matter. If they didn't notice it and just wrote the case closing report, they might be punished for dereliction of duty.
Du Anping died more than a month earlier than Qiao Yulan. Did he kill Qiao Yulan as a ghost?!
Liu Jun was furious and grabbed his hat to go to the detention center to settle accounts with Qu Jingyun, but was stopped by Gao Huanyu:
"Let's go to the Qi family!"
Liu Jun was stunned for a moment and asked:
"Why go to the Qi family at this time?"
Gao Huanyu brought the new evidence to Liu Jun, his eyes gleaming:
"What do you think this is?"
Liu Jun was a little puzzled. What could a stationery knife mean?
Gao Huanyu explained with a little excitement:
"We guessed correctly. Qu Jingyun couldn't kill Qiao Yulan or move her body by herself, so she must have had help. But Du Anping is already dead, so her helper must be someone else."
"Although stationery knives are common, they are not a must-have for everyone. They are only necessary for one type of people—"
"student!"
Liu Jun and Gao Huanyu shouted the same answer in unison.
Liu Jun's face turned red with excitement. After working with Xiao Gao for so long, he finally caught up with his thinking pace!
"Let's go! Go to the Qi family!"
After many twists and turns in this case, the truth was finally revealed. The two men could not contain their excitement and rushed to the Qi family in a hurry.
The police car stopped at the gate of the Qi family compound. Liu Jun got out of the car and rang the doorbell. Soon a servant opened the door and invited them in.
After staying in the hospital once, Qi Mingyuan was not as hard-working as before, and he returned home much earlier than before. When he heard that the police had come again, he invited the two of them to the study.
Gao Huanyu did not waste time and said bluntly that the purpose of this trip was to bring Qi Guangyao back to the police station for questioning.
Qi Mingyuan's heart sank suddenly. He originally thought that the police came because there was new progress in Qu Jingyun's case, but he didn't expect that they came to talk to Qi Guangyao and take him back to the police station?
An ominous thought suddenly arose in his mind, and even his voice trembled slightly:
"Could it be that Qi Guangyao is also involved in this poisoning case?"
Gao Huanyu noticed Qi Mingyuan's nervousness and sighed inwardly:
"It's not about the poisoning case. There's something else involving Qu Jingyun that I need to inquire about from him. Is he home?"
Hearing that it had nothing to do with the poisoning case, Qi Mingyuan felt relieved. He thought that it was just to understand some of Qu Jingyun's past, so he answered:
"At home, ever since that mother's incident, he has stayed in his room every day. He rarely goes out, and even has his meals delivered to his room."
Gao Huanyu and Liu Jun looked at each other. In their opinion, Qi Guangyao's behavior further showed that there was a problem.
Gao Huanyu said calmly:
"Then please lead the way. We need to take him back to the police station to cooperate with the work."
Qi Mingyuan was worried that the two police officers would scare Qi Guangyao if they knocked on the door rashly, so he took the initiative to accompany Gao Huanyu and the other two to the third floor. However, no one answered the door after knocking for a long time.
Gao Huanyu lowered his head to glance at the crack in the door. It was pitch black inside and it was obvious that the lights were not on.
Liu Jun showed an anxious look on his face. He walked forward and knocked hard a few times, shouting loudly as he knocked:
"Qi Guangyao! Open the door!"
Qi Mingyuan seemed to sense something was wrong and after a moment's hesitation he said:
"He's been in a bad mood lately and might have fallen asleep by now... Otherwise, I'll personally take him to the police station for investigation tomorrow morning."
Liu Jun snorted coldly:
"What time is it already?! Even if you're asleep, you can't be woken up by such a loud noise?! Quickly get someone to open the door, or I'll have to resort to violence!"
Qi Mingyuan looked at Gao Huanyu, only to see that Gao Huanyu had a serious face. He finally confirmed in his heart that something must have happened to Qi Guangyao!
Seeing Qi Mingyuan was unmoved, Gao Huanyu said in a deep voice:
"Mr. Qi, Qi Guangyao is still young. Even if he made a mistake, if he admits it and corrects it, there might still be hope. But if he makes more mistakes, he's finished!"
Having said that, what else could Qi Mingyuan not understand? He sighed heavily and asked someone to bring the key to open the door, but even with the key, the door couldn't be opened.
Liu Jun knew something was wrong, the door must have been locked from the inside!
He immediately kicked the door lock several times, forcing it open, and turned on the light -
The room was empty, and there was no trace of Qi Guangyao!
