Lin Yi and the person in charge of the hospital glanced at each other, and their expressions were suddenly a little shocked and confused.

According to Tang Cheng's inference, the person on the screen is Chen Xi who has changed into someone else's uniform. She is petite, and her loose and fat clothes hide her body, making it difficult to judge.

It's no wonder that Lin Yi feels that this figure is both familiar and unfamiliar.

"She was very clever in using her left hand to draw the drug, deliberately making people think that she was a left-handed person, and she herself was used to using her right hand so that she would not be suspicious." Tang Cheng added, "It's a pity that the details betrayed her." She didn't look very skilled with her left hand, and she was so anxious when changing clothes that she forgot to take off the ring on her right ring finger. ”

The truth came out, but Chen Xi's motive for doing so was even more intriguing.

Before she did this, she must have known that the teenager Lin Yi nursed was allergic to penicillin, and the exchange of drugs to cause medical accidents was aimed at the teenager? Or is it for Lin Yi?

This is a question that only she can answer.

When the few people returned upstairs, Chen Xi was walking out with a heavy heart.

Tang Cheng stretched out his hand to stop her, and the corners of his mouth hooked slightly, "Where is Head Nurse Chen going?" ”

"The patient needs to be nebulized, and I'll pick up the equipment." Chen Xi's gaze swept over a few people and fell on Lin Yi, "How is the medical malpractice handled?" When something like this happens, I don't have any other way than to wish you good luck. You've been very absent-minded lately, and you've been late in the morning, but I didn't expect you to make such a big mess at work......"

Chen Xi's critical tone made Lin Yi feel indignant, obviously she was secretly playing ghosts, but now she put on a preachy face, Lin Yi couldn't wait to punch her stinky face.

Just as she was about to step forward to expose Chen Xi's trickery, a siren suddenly sounded outside.

With the evidence in hand, Lin Yi naturally has no fear. On the contrary, the expression on Chen Xi's face changed, showing a little uneasiness.

A few minutes later, the nurses' station was surrounded by police forces. The crowd parted automatically, making way for a tall officer with a handsome face, and slowly stepped out of it, scrutinizing it.

"Who called the police?" The tone is full of breath and loudness.

Turing 5467 collected information through Tang Cheng's optic nerve and quickly completed identity analysis.

"This person is the captain of the Jiangcheng Criminal Investigation Detachment, Du Chen."

"Hello officer, it's me who called the police." Tang Cheng stepped forward and stretched out his hand with a smile.

As a result, Du Chen passed him and walked straight to Lin Yi, looked down, and glanced at her badge.

"You're Lin Yi?"

"It's me." Facing the cold questioning, Lin Yi's answer was neither humble nor arrogant.

Being ignored head-on, Tang Cheng withdrew his hand in embarrassment, shook his wrist, and put his hand back into his trouser pocket.

"When I came, there was a corpse parked downstairs, and I heard from onlookers that it was a nurse named Lin Yi who killed someone by giving an injection. Ten minutes ago, the bureau received a call that someone had murdered someone here, and I guess this is it. Du Chen stared at Lin Yi for a moment, "But judging from your reaction as the number one suspect, this matter doesn't seem to be that simple." ”

Sure enough, Jiang is still old and spicy, and the criminal investigation captain can see the clue at a glance.

"We have retrieved the surveillance footage, and there is another black hand behind this medical accident!"

The person in charge of the hospital explained to Du Chen the reason why the drugs were transferred, and Du Chen asked other police officers to collect evidence on the drugs in the tray, and he personally went to the monitoring room to confirm the content of the video.

During this time, Chen Xi wanted to leave under an excuse, but was stopped by Tang Cheng on the pretext of assisting in the investigation.

In the surveillance room, the video was played back again.

Du Chen's eyes were like torches, and he finished watching the whole process. However, without waiting for him to make a scrutiny, the person in charge of the hospital said the key clues pointed out by Tang Cheng just now.

After listening to this, Du Chen's face suddenly became awe-inspiring. Although he could understand the incomplete account of the person in charge of the hospital, he was sure that this person was not the first to discover the clues.

It can quickly identify the suspect's "left-handedness" as a disguise, and directly judge the marriage and love status with the ring finger ring, so as to quickly lock the suspect's identity. A person who understands such inferences must have sharp thinking and strong logical reasoning ability for the case.

His first reaction was that the other party might be a peer.

"Who found out?" Du Chen couldn't help but ask.

"It's Dr. Tang, the one who called the police." The person in charge of the hospital replied truthfully, "He is a doctor from the municipal hospital, and he came to see Nurse Lin and happened to run into this medical accident." ”

"So it's him?" The result was a little unexpected, and Du Chen sighed as if talking to himself, "It's not simple." ”

Tang Cheng's inferences happened to coincide with his thoughts.

When he returned to the front desk of the nurse's station, when he saw Tang Cheng, he changed his previous cold and arrogant attitude and took the initiative to shake hands.

"Has Dr. Tang worked in any other jobs before?"

Tang Cheng was slightly surprised by the 180-degree change in attitude.

"Nope." He smiled and replied, "I'm an orthopedic surgeon, and always have been." ”

"Reasoning?"

"Veteran mystery fan. But in front of you professional criminal investigators, I don't dare to say 'I understand'. ”

"Humble." Du Chen patted Tang Cheng on the shoulder, then walked towards Chen Xi and repeated the inference drawn from the surveillance video, "Compared to others, Nurse Chen has enough time to commit crimes, even if you change into a colleague's uniform and pretend to be left-handed, the ring on your right ring finger still betrays you." And as far as I know, among the nurses on duty in this department, you are the only one who is married. What else do you have to say? ”

Under normal circumstances, when Captain Du's serious and cold words came to this, the suspect had already timidly confessed to the crime, but Chen Xi's face only changed slightly, and then he calmly responded.

"Comrade policeman, you can't judge anything by just a ring, right? You say I'm pretending to be someone else's left-hander, so is it possible that someone else is wearing a similar ring and pretending to be me? ”

When Chen Xi's words came out, the person in charge of the hospital and Lin Yi were directly dumbfounded. The conclusion that the two of them still believed in just now was destroyed a few seconds after Chen Xi opened his mouth, and he was vulnerable.

Du Chen's eyebrows rose slightly, and a shallow "Sichuan" character print appeared in the center of his eyebrows.

He was not in a hurry to debunk Chen Xi's defense, but after a sneer, he turned his head to Tang Cheng.

"The benevolent see the benevolent, and the wise see the wise. What is Dr. Tang's opinion on Nurse Chan's statement? ”

"Of course, the investigation of the case must be based on evidence, and anyone can make bold assumptions and inferences." Tang Cheng crossed his arms and walked to Chen Xi's side calmly, and was about to pass by her, when he suddenly turned around and picked up a hair from her uniform, "Postpartum hair loss generally appears about two to seven months after childbirth, and it worsens with the number of pregnancies. Nurse Chen is 32 years old this year, not long after giving birth to her second child, right? ”

Chen Xi was a little uneasy, "What does it have to do with this?" ”

Tang Cheng raised the corners of his mouth, "When you changed your clothes, you wore someone else's nurse's hat." Hair loss is severe, but the hair will stay on it......"
