Everyone looked up and saw Hu Jia walking back and forth along the parapet of the rooftop.
"Captain Hu, what are you doing? Come down quickly." Although the prison guards were displeased with Lü Qingqing's actions, they were very panicked to see Hu Jia standing on the rooftop.
Was this man risking his life to investigate the case? What if he lost his footing and fell?
But Hu Jia seemed not to hear them, continuing his way. Suddenly, he shouted "Freedom!" and then jumped over the railing. Lü Qingqing's face changed dramatically. "He's not going to imitate Fan Yafu, is he?"
Then a bang was heard, and everyone's faces changed dramatically. They rushed towards the back of the dormitory building.
As mentioned earlier, the dormitory building itself was built on a slope, which meant that circling from the front of the building to the back was not as simple as just walking around a building.
You also had to go uphill and downhill.
By the time they reached the back of the building, they found a person lying on the ground.
"Oh no! Captain Hu jumped off the building!" With a cry, everyone was too scared to think straight. How could a case investigation lead to a death?
A prison guard, who was running at the front, was the first to reach Hu Jia. But as soon as he turned him over, his face froze.
Hu Jia was staring at him with wide-open eyes, and then he winked.
"You, you..." The prison guard was almost scared to death.
Hu Jia rolled over and stood up. "Who said I jumped off the building? Did you see me jump?"
Uh...
Everyone was speechless.
"Captain Hu, this joke is too much," someone complained.
Hu Jia didn't get angry. He just smiled and pointed upwards.
Everyone looked up and saw a head poking out from the rooftop. It was Li Yang! He had just arrived at the prison and had cooperated with Hu Jia in putting on this act.
"As you all saw, it was never Captain Hu standing on the rooftop, but I shouted 'Captain Hu', so you all thought it was him. From beginning to end, did any of you doubt it?" Lü Qingqing scanned everyone, finally focusing her gaze on Fan Jia's younger sister.
The young girl was also smart and immediately understood Lü Qingqing's meaning. "So, the person on the rooftop at that time might not have been my brother?"
Lü Qingqing nodded.
Everyone erupted in an uproar!
"Who was the one who first shouted Fan Yafu's name? Can you recall it now?"
Everyone shook their heads.
"Are you sure that the shout of 'Freedom' you heard was Fan Yafu's voice? Just like that shout of 'Freedom' just now, because of the current environment and your preconceived notions, you didn't even consider that it was someone else imitating him."
Everyone fell silent.
"We found three wounds on Fan Yafu's head, on the top of his head, his brow, and his ear. These three places are in different positions on the head. Can any of you tell me how a fall could cause severe injuries to the top, side, and front of a person's head all at once?"
Following Lü Qingqing's pointed questions, everyone began to realize.
They were all police officers and had some experience. They had not believed that Fan Yafu died by murder because they were convinced that what they saw was the truth.
But after Hu Jia conducted this experiment, they could naturally analyze the clues with a calm mind.
"So, there is a murderer among us!"
...
The autopsy proceeded smoothly. Hours later, Lü Qingqing appeared in the office with an autopsy report.
"It's confirmed, it was murder. And he was already dead before Fan Yafu fell," Lü Qingqing's conclusion stunned everyone in the office except Hu Jia.
Li Bei, the prison warden, was the first to take the autopsy report. "Is there any direct evidence?"
"Of course!" Lü Qingqing said. The external examination and dissection revealed punctate hemorrhages in the conjunctiva of the deceased's lower left eyelid and patch hemorrhages in the inner canthus of the right eyeball; widespread punctate hemorrhages under the epicardium, and patch hemorrhages in the intermediate pleura of the middle and lower lobes of the right lung, all clear signs of death by mechanical asphyxiation.
"However, a simple fall from a height would not result in so many signs of asphyxiation. There must have been an external human cause leading to mechanical asphyxiation." Lü Qingqing then presented a few more pages. "The wounds on his head were caused by multiple blows."
Lü Qingqing explained that even if the same part of the human body was struck twice, the wound would show two marks because it was impossible for the second wound to completely cover the first.
And she found a second trauma on Fan Yafu's head.
Furthermore, if a blow caused a fracture, the fracture line would extend.
To make it easier for everyone to understand, Lü Qingqing took out an egg. "Let's imagine the egg as a human skull, and hitting it with a spoon as a blow. You can see the cracks on the egg, which are equivalent to fracture lines. These cracks radiate outwards. Of course, an actual skull is not that fragile, nor does it have so many fine lines, but the principle is similar."
As she spoke, Lü Qingqing hit the same spot on the egg again. "Look again. When you hit the egg a second time nearby, you'll find that some of the radiating cracks are cut off by the first crack. This forms a structure resembling a 't' shape. This is mainly because the force transmitted along the crack is dispersed when it reaches the already formed gap and cannot continue forward."
And in the autopsy report provided by Lü Qingqing, Fan Yafu's skull fracture lines showed such a situation. "Therefore, the real killer is inside the prison and cannot escape."
...
Leaving the office, Lü Qingqing and Hu Jia finally breathed a sigh of relief.
They had bought time for the investigation, gained the cooperation of Fan's family and all the prison guards, and most importantly, they had obtained permission from the prison to investigate Fan Yafu's fall case.
After all, when you're working on someone else's turf, not getting approval can be a troublesome matter, and you might not even be able to interview someone for a statement.
"We need to find the other mole as soon as possible," Hu Jia judged. "Because only someone living in the prison could have attacked Fan Yafu."
"Whoever ordered Fan Yafu to escort Zhang Hangjiang is the most suspicious," Lü Qingqing agreed. "I inquired, and it was the office director, Tang Bing."
"The target group is clearly defined, the criminal scope is locked, and I believe this case will be solved soon," Hu Jia nodded.
Lü Qingqing was also full of confidence. She looked up and saw the setting sun in the distance. This day had not been wasted after all.
"Hey? Doesn't that person look like Tong Meng?" Lü Qingqing said, looking at a figure in the distance.
"It's her. I just chatted with her. She said she was here to submit a sentence reduction application," Li Yang said.
"Sentence reduction application?" Hu Jia asked.
"Yes, for Zhang Hangjiang. After all, he made a contribution to the Tuwan Village case, so the Municipal Bureau expressed its stance, as a way to encourage other inmates to confess and be lenient." Li Yang explained.
Tong Meng walked forward with a smile and greeted Hu Jia. Hu Jia nodded slightly. This woman was on his notebook: "Cannot touch, stay away, knife person, traitor!"
"I heard about what happened in the prison. I didn't expect Captain Hu to be so capable, to have discovered such a hidden method of crime."
Tong Meng's words sounded like flattery, but to Lü Qingqing, they sounded like a provocation.
Why was this woman here?
As a "knife person," was she here to check if her pawns had been uprooted?
Tong Meng's alarm bells were ringing. Was she going to get rid of that Tang Bing?
