CHAPTER 313: CHAPTER 198: JIANG AN’S TRUMP CARD

Immediately, Mr. He also turned his head to take a look.

"Jiang An came at just the right time, let’s see if he has any good ideas."

From a distance, walking over and seeing two people smoking in the hallway, he knew the interrogation wasn’t going well.

"Mr. Zhang!"

Zhang Feng stepped forward, softly saying, "You must be exhausted!"

"Is the interrogation not going well?"

The two people opposite both shook their heads.

"This woman is very cunning, she never admits to her crime."

Mr. Zhang had a face full of worry and sighed.

"Even though we internally believe she could very likely be the murderer, we’re at a dead end."

Mr. He also stepped forward, "Exactly! Right now, the biggest thing we’re lacking is objective evidence."

After a moment of contemplation, Jiang An said, "This woman has motive, capability, and is familiar with the environment."

"These are all important characteristics of a case suspect."

Mr. He also said in a deep voice, "Indeed!"

"The crime scene is an abandoned office building, no surveillance, now where can we find evidence."

Suddenly, Jiang An spoke in a deep voice, "I have a method that we might try."

Upon hearing these words, Mr. Zhang and Mr. He were a bit surprised.

Both of their eyes were filled with anticipation, looking directly at Jiang An.

"What method? Quickly, tell us."

Mr. He expectantly tugged on Jiang An’s arm.

Like a drowning man clutching at a straw.

Even Zhang Yean and Wan, standing behind Jiang An, had surprised looks on their faces.

Earlier, the three of them went to examine Zhang Yan’s house and also went to the hospital to consult with professional doctors.

Why did he suddenly have a good method and clever trick?

Zhang Yean and Wan glanced at each other, both seeing confusion in each other’s eyes.

Then, Jiang An began to speak, "Just now, when we were in the hospital learning about Zhang Yan’s condition, the attending physician reported that Zhang Yan had a fracture in her right elbow a month ago.

"A fracture a month ago?"

Thinking about the case that happened two months ago, a suspicious look appeared on Mr. He’s face.

Mr. Zhang was also quite surprised.

He asked, "Brother Jiang An, is this fracture related to the case?"

"After all, there’s still a one-month gap in terms of time."

As everyone was puzzled, Jiang An analyzed, "Just now, we went to the hospital to find the doctor who performed a termination procedure for Zhang Yan."

"He reported that Zhang Yan visited a month ago for pelvic issues."

"Moreover, during the visit, Zhang Yan also mentioned pain in her right arm and asked the doctor to take a look."

"The attending doctor suggested she get an X-ray."

"Although the visit was a month ago, after seeing the fracture situation in the X-ray, I considered the fracture should have occurred around two months ago."

"Around two months?"

Instantly, Mr. Zhang and Mr. He both showed surprised expressions on their faces.

Zhang Feng asked in a serious tone, "Brother Jiang An, can we further refine the timing?"

Jiang An thought for a while.

"The inference of fracture healing time is merely a high-probability event."

"To pinpoint a specific day, there is currently no unified standard, and the error margin is relatively large."

After a slight pause, he said, "No, from my personal experience, the time the fracture formed should be relatively closer to when the incident occurred."

"Closer in terms of time?"

"Is this enough as case-related evidence?"

Jiang An nodded.

"Mr. Zhang, you have a point."

"However, aside from the timing, there’s another reason."

"What reason?"

Jiang An said in a deep voice, "I remember Zhang Yan told the attending physician that the fracture in her elbow was due to a motorcycle fall."

"But, from my personal analysis of fracture morphology."

"I believe it wasn’t a direct violent impact, but a pulling that caused an avulsion fracture."

Upon hearing the professional term "avulsion fracture," everyone present became interested.

"That’s so profound! What is an avulsion fracture?"

Zhang Yean asked curiously.

Mr. Zhang was no stranger to many forensic terms due to his frequent interactions with forensic experts.

Terms like livor mortis, rigor mortis, corneal opacity, mechanical violence...

However, this was the first time he encountered an avulsion fracture.

"Is this kind of fracture very special?"

"Please explain to us."

Mr. He was overwhelmed by the case.

Now finally there was a major breakthrough.

He hoped to strike while the iron was hot and quickly find solid evidence.

Then, Jiang An said in a deep voice, "An avulsion fracture is very different from a typical fracture."

"An avulsion fracture is caused by the muscles in the human body pulling at the joint area."

"For fractures in this area, it is often due to intense muscle contraction leading to a local fracture, which is very different from the fracture caused by a typical violent impact on the area."

"Moreover, from my view, if it was a fracture caused by a fall in a traffic accident, it would often form from direct contact of the body with the ground."

"Therefore, in analyzing the fracture of Zhang Yan’s right elbow, I am confident in my conclusion."

"Zhang Yan did not tell the truth about the mechanism of fracture formation."

"From a forensic perspective, an avulsion fracture is not easy to form."

"Moreover, only during a massive pulling force on the joint could such an avulsion fracture occur."

"As I see it, the moment of muscle pull on the joint, the force is unpredictable."
