After amnesia, I became a forensic doctor

Chapter 1072 The Final Murderer 89
"Regional Police Station." Lao Yang showed his ID.

Three plainclothes officers immediately stood up, and the oldest one held out his hand. "Hello, my name is Sun Yun, the police officer in charge of escorting you."

"Hello, Officer Sun, we have been in contact before." Lao Yang shook hands with him. After coming out of Hai City, Officer Sun had been in contact with him. The call just now was made by him.

"Hello, Officer Yang."

"This is... our single team." Lao Yang introduced.

"Hello, Team Shan." Sun Yun greeted.

Shan Chenxun nodded, he squatted down and looked at the person on the ground. Qian Wenjun was seriously injured and his body was covered in blood.

His abdomen was wrapped in bandages, and blood was still seeping out of the snow-white bandages. He had his eyes closed, his face was pale, his lips were bloodless, and his breathing was weak.

"The wound has been treated and the bleeding has basically stopped. There should be no danger to his life," said Sun Yun.

"Fortunately, the aorta is not injured..." a man next to him spoke. He was the doctor on the car and he treated the wound urgently for him immediately.

Shan Chenxun stood up, looked around and asked, "What's going on?"

"It's like this. Qian Wenjun wanted to go to the toilet an hour ago, so Officer He took him to the toilet. In the toilet, he was attacked and stabbed three times!" Sun Yun explained the situation.

"Who is it?"

"I didn't see anyone..."

"Where's Officer He? Didn't you see him?" Old Yang interrupted.

"No." He shook his head. "The man was lurking in the toilet beforehand. After stabbing Qian Wenjun, Officer He heard the noise and rushed in, and was also stabbed!"

He pointed to the back of the car, and Lao Yang discovered that there was a plainclothes officer sitting there. He was leaning back in a chair with one hand covering his abdomen, with cold sweat on his face.

"Officer He was stabbed in the side of his abdomen, but no vital parts were injured..."

"Didn't you check before going to the toilet?" Gao Shan interrupted him. How could someone in the toilet not know?
"It was our negligence..." Because it was a reserved carriage, they informed the conductor in advance and prohibited other passengers from using this toilet. "It was our inconsiderateness!"

"How could you be so careless!" Lao Yang found it incredible. After all, he was a police officer in a first-tier city, but he didn't have such vigilance?
Gao Shan frowned, also in disbelief.

Shan Chenxun's eyes shuttled back and forth between the four police officers, and after a moment he spoke, "Did you check the surveillance?"

"I checked, but the signal was interfered during that period and we couldn't see the picture," said Sun Yun.

"What a coincidence?" Shan Chenxun raised his eyebrows, "Is it man-made?"

"Probably." another police officer replied.

Shan Chenxun didn't say anything, but gestured to Gao Shan, who immediately called in the medical staff who had been waiting outside.

They carried Qian Wenjun off the train and took him to the hospital under police escort.

Four police officers originally wanted to follow, but were stopped by Shan Chenxun.

Shan Chenxun whispered a few words to Lao Yang, and Lao Yang's eyes flashed, and then he ran out of the car...

He asked the conductor to arrange for the passengers to get off the train, leaving only all the staff on board.

More than a dozen staff members and four plainclothes officers went to carriage No. 3 together.

"Boss, why are you letting the passengers get off?" Gao Shan was puzzled, watching a large number of passengers getting off the train outside the window.

"Because the attackers are not ordinary passengers..." Shan Chenxun stood in front of everyone and deliberately spoke loudly. "It's them, among these people." Everyone looked at him in surprise, especially the four plainclothes officers, who were shocked.

"Captain Shan, do you mean to say that you suspect us too?" Sun Yun said angrily, "We are the police!"

"Don't be anxious. If it weren't for you, I wouldn't have wrongly accused you." Old Yang just came back and said immediately after hearing this.

Sun Yun stopped talking and sat on the chair. Everyone looked at Shan Chenxun, waiting for him to speak.

Shan Chenxun was not in a hurry. He walked around twice in front of everyone and observed their expressions. Everyone looked calm and nothing could be seen.

"My suspicion is well-founded. High-speed rail stations require security checks, and ordinary passengers cannot bring dangerous items on board. But you are different. Compared with other passengers, the station's requirements for you are relatively relaxed, especially for the onboard doctor, the train police, and the four escorting police officers..." He looked at Sun Yun, "Officer Sun, the four of you all have your guns, right?"

"Yes." They explained their identities to the station and were allowed to carry guns, "...but the weapon used to attack the criminals was a dagger, and we don't have it."

"Are you sure? Did you check at the station?"

"Although there was no security check, we provided gun checks and we checked each other. Apart from handcuffs and guns, there were no other threatening weapons." Sun Yun knew the rules, and the guns of the four of them were also checked by security personnel.

"Where are the doctor and the flight attendant?" Gao Shan asked.

"I only have a small scalpel, which I use in emergencies, such as cutting wounds and opening airways..." The doctor took out the scalpel and gave it to them, then opened the medical box.
Old Yang took it and examined it. The scalpel was very short, only about two centimeters. With such a small knife, its lethality was greatly reduced and it was not enough to kill a person.

Judging from Qian Wenjun’s wound, it was definitely not this knife.

He checked the medicine box again, and it was filled with gauze and medicine, but no other knives.

"I only have this service gun." The police officer handed over the gun. "We have regulations that you cannot carry other weapons except handcuffs and service guns. They are all checked by security personnel before boarding the train."

"Staff members in the restaurant on the bus, please come out." Shan Chenxun glanced at everyone.

A man and two flight attendants stepped out. They were the chef and the waitress responsible for selling food and beverages.

The chef said he had never left the food preparation room and there were surveillance cameras inside that could prove it.

Lao Yang checked the surveillance footage and found that the chef did not lie and he had indeed been in the food preparation room the entire time.

"What about you?" Gao Shan asked the two waitresses.

"I didn't! I was the one selling things today! How could I have the time to kill someone!?" Because it was an evening train, not many people were eating, so she was the only one responsible for selling.

"I didn't say you killed anyone!" Gao Shan glared at her, "Why are you panicking?"

"Officer, I really didn't do that!" The girl was eager to explain and kept waving her hands, trying to prove her innocence.

The other waitress, on the other hand, didn't say a word. She was very calm and just looked at the policemen without saying anything.

Shan Chenxun noticed her and saw her glance to the side, but he still caught the subtle look.

He glanced at her, a gleam of light flashing in his eyes.

"Where were you when she was selling?" he asked, looking at the woman.

"I'm tidying up in Carriage 8." Carriage 8 is the restaurant, with several tables of guests, and she was busy clearing the tableware. "There's surveillance footage as evidence."

"The surveillance camera in carriage number three broke down at 10:30. Where were you then?" Shan Chenxun continued to ask. The man had a cold expression and it was impossible to guess what he was thinking. His sharp eyes made people terrified.
