"Didn't you say it, don't break in casually if you have nothing to do with it." Yan Junli looked at Wang Jianshe with some annoyance.

"No, officer, listen to me! The murderer can't be anyone else except Yang Wenbin, Yang Wenbin has long been plotting against my brother. There was an argument the day before my brother's accident, and my brother scolded him for his leg and almost didn't move. Today he killed my brother in a fit of rage! Wang Jianshe was still yelling, I don't know if it was because he was angry or sad, his eyes were red.

Yan Junli had a headache, and hurriedly raised his hand to make a pause gesture.

"Okay, okay, I didn't say I wouldn't listen to you, but can you make it clearer? Start at the beginning. Who is Yang Wenbin? Who is your brother? ”

It seems that Wang Jianjian's language skills are not very good, he stood there sweating profusely for a long time, and Yan Junli didn't understand what he wanted to say. A young man standing next to him spoke.

"Police officer, Wang Jianshe is the younger brother of Dr. Wang Jianshu." The young man said, "The Yang Wenbin he said is the chief surgeon who works in surgery like Dr. Wang Jianshu, and the office of the two people is next door.

Yan Junli turned his gaze to the doctor named Yang Wenbin again, Yang Wenbin was standing not far from him, his eyes looking this way, and he didn't know if he heard their conversation. Since Wang Jianshe had mentioned Yang Wenbin's leg before, Yan Junli also paid a few more attention, it seemed that Yang Wenbin's leg was a little lame, but he stood stubbornly, without the slightest intention of finding a place to sit down.

With Gu Yan's help and explanation, Yan Junli finally figured out what was going on. It turned out that the young intern's name was Gu Yan, and he was the intern assistant of the deceased Dr. Wang. The physician named Yang Wenbin, who was the chief surgeon of surgery with the deceased, seemed to have some contradictions with the deceased, and the deceased's younger brother Wang Jianshe insisted that Yang Wenbin was the murderer of the deceased.

"You are Yang Wenbin?" Yan Junli turned around, this mediocre-looking doctor made him can't help but want to guess his age. Although he doesn't look old, his performance is too calm, and his expression is not like others, very calm.

"I'm Yang Wenbin." The doctor nodded, his gaze meeting Yan Junli.

At that moment, Yan Junli had an illusion, as if he had seen something special in the eyes of this ordinary doctor.

At this time, Li Hong, who had been checking the corpse, straightened up from the front of the corpse and said to Yan Junli, "Team Yan! The time of death was between two and four o'clock last night. The deceased died from a puncture in the heart, the wound was small, but it was very accurate, and he died on the spot with one blow. The murder weapon should be a scalpel or scalpel. ”

"Who can get a scalpel or a scalpel in the hospital?" Yan Junli turned around and asked the doctors and nurses outside the room.

Gu Yan glanced at the people around him and said cautiously, "Uh...... This is probably available to every doctor and nurse in the hospital. It's not a rare thing. ”

"What about people other than doctors and nurses?" Yan Junli asked, "For example, patients who come to see a doctor?" ”

"It's not very likely." A nurse shook her head, "The hospital is so big and the structure is quite complicated, so it's not easy to find a place to put medical equipment." In addition, there are security guards nearby, and they will stop them when they see unrelated people breaking in. ”

Yan Junli nodded clearly and came to a conclusion, "Then, nine times out of ten, the murderer is a doctor or nurse in the hospital." ”

There was an immediate commotion in the crowd, and everyone looked at each other with flickering expressions, for fear that the person next to them would be the murderer.

"So," Yan Junli turned, "who was the last person to see him last night?" ”

"At eight o'clock last night, everyone who was not on the night shift went home." A nurse spoke, "It was Doctor Wang and his assistant Gu Yan who were on the night shift in surgery last night. The doctor on duty in the Department of Internal Medicine is Dr. Wang Jianjian. ”

"And what about the other sections?"

"There are only surgery and internal medicine departments on the first floor of the hospital, and the other departments and surgical departments are not on the first floor. If the doctor from the Besko department came down to kill someone, he had to go through the elevator or stairs, and the guard would definitely notice. Yang Wenbin said, "And after nine o'clock in the evening, for the sake of safety, the hospital needs a door card to get on and off the elevator, and even the patient must be led by someone with a key card to get on and off." As soon as the records of the key card are checked, it is very unlikely that the doctor from Beko will come downstairs to kill someone. ”

"So Doctor Yang, where were you in the early hours of last night?" Yan Junli's sharp gaze was projected on Yang Wenbin.

“…… Me, it wasn't my shift last night, so I slept at home. ”

"Can anyone prove it?"

"Nope." Yang Wenbin shook his head, "I live alone. ”

"What to sleep at home! You obviously took this opportunity to kill my brother to avenge your personal revenge! Wang Jianshe yelled, and pointed his index finger at Yang Wenbin, "You don't have an alibi at all!" ”

"Wang Jianjian, what about you?" Yan Junli frowned.

"Huh? What am I? ”

"Where's your alibi?"

"I ...... Of course, I've been writing work reports in the office and haven't been out of the house! ”

Yan Junli laughed, "You haven't gone out a single step, isn't there no one who can prove your alibi?" ”

"This ...... This ......"

"What about you?" Yan Junli turned his head to his assistant Gu Yan and asked, "What were you doing last night?" ”

"I ...... At that time, it was supposed to be a person who was sorting out the data in the database. Gu Yan lowered his head and thought, "Ah, by the way, I came out to pour a cup of coffee at half past two, and Nurse Zhang at the front desk should have seen me." ”

Nurse Zhang, who was on the side, immediately thought about it when she heard this, nodded and said, "Yes, I remember, it was exactly half past two, I saw him come out of the reference room, and he complained to me that he was tired and panicked to sort out the materials, so I asked him to ask Dr. Wang for a bonus after finishing it." Alas, I didn't expect Dr. Wang to ...... today"

Yan Junli nodded, swept over the few people in front of him, frowned, and finally set his eyes on Yang Wenbin. But before he could say anything, a voice interrupted him.

"Strict team! Come here! ”

It was Shi Lize who he had just sent to investigate the surveillance video.

"What's wrong?"

"Oh no...... That, that surveillance video, it's so weird, you have to come and see it! Shi Lize's face was flushed, as if he wanted to explain but couldn't explain it clearly. Yan Junli had no choice but to leave Wang Jianshu's office and follow Shi Lize out.

The surveillance video shows Dr. Wang's office, which was before the crime, and Dr. Wang was flipping through the information and drinking tea under the camera, which lasted for about five minutes. Then, Dr. Wang stood up and walked out the door, looking like he was going to relieve himself. Then the picture became an empty office, and this picture lasted for a long time, about 20 minutes, so the staff simply pressed fast forward.

"Aren't there any surveillance cameras in the hallway outside the office?" Yan Junli interjected.

"Originally, there was, but it broke down last month, and no one has been taking care of it." The staff replied.

"Team Yan, look at it, it's about to get to the point!" Shi Lize urged, so Yan Junli's gaze returned to the surveillance video.

After more than 20 minutes of blankness, Dr. Wang, wearing a white coat, returned to the picture, sat down, and began to flip through the book. Just when Yan Junli had already begun to arrive impatiently, the picture suddenly burst with snowflakes, and then became pitch black.

"What's going on? Did the murderer do it? ”

"No, it's just that the monitoring system is aging, and occasionally there will be a short circuit, and it usually only takes a few seconds to be fine, but ......" The staff was a little embarrassed, and didn't say anything anymore, just pointed to the screen.

The time is indeed very short, the black screen lasts less than ten seconds, and the picture is clear again. But the picture presented on the screen shocked everyone.

On the screen, Dr. Wang's face was stiff and lifeless in his chair, blood oozing from his chest.

"This ...... This, how is this possible? Yan Junli stood up suddenly, "There were only less than ten seconds in the middle, and the murderer actually killed Doctor Wang without a trace?" And how could the murderer have predicted the precise time of the short circuit and then come to the office to kill someone? He is not God! ”
