Cao Mingyang soon developed acute respiratory failure, and at the same time, the tremors of his body were also rapidly weakening. Ten minutes later, his breathing and heartbeat stopped, and the doctor hurriedly pulled up the bed curtain, told Xun Mu and others to leave, and immediately did cardiopulmonary resuscitation inside.

Unfortunately, it could not be rescued, and after 30 minutes, the bed curtain was torn open, and all kinds of first-aid medical equipment were removed.

The chief physician walked out, shook his head, and said, "I'm sorry, people...... I can't get it back. ”

As he spoke, he sighed lightly, looked at the doctor Qi Yuan called earlier, and said, "Xiao Liu, you go and give a medical certificate of death." ”

After a pause, the doctor looked at everyone again and asked, "Are the families of the deceased there?" ”

At this time, Cao Mingyang's parents had already fallen into a sluggish state, and his younger brother and Sister Xun had red eyes and were a little stunned.

After a few seconds, Sister Xun walked up with red eyes, choked up and said, "Doctor, I'm ...... I'm his wife. ”

The old director looked at her and said softly: "Notify the funeral home, the death certificate, we will issue it to you later." ”

"Doctor, really...... Is it really not working? The young man couldn't help but ask, "Please, can you ...... again?"

The old director shook his head lightly, and looked at Su Ping again: "Team Su, please come with me." ”

"Okay." Su Ping bowed his head, and said to Qi Yuan again: "Xiao Qi, you go and clean up, put away all the vomit, and notify Lao Yan to come over." ”

After a pause, he said to Sister Xun again: "I'm sorry, you can't notify the funeral home for the time being, the case hasn't been investigated yet, we must find out the cause of Cao Mingyang's death." ”

"Yes." The old director shook his head again: "I almost forgot, this is not an ordinary death, it is likely to be poisoned......"

With that, he turned and walked towards his office.

Su Ping explained Qi Yuan in detail a few more words, and pushed Xun Mu to bring him back to his senses, and then ran to the doctor's office.

At this time, a pair of old people seemed to have just reacted, and as soon as their feet were soft, they sat on the ground one after another, tears could not stop flowing, and their mouths grew old, as if they wanted to cry bitterly, but they couldn't make much sound at all, and their throats seemed to be choked.

"This ......" Qi Yuan was stunned, suddenly a little embarrassed, looked at the ward, and then at the two old men, he didn't know what to do for a while.

Xun Mu shook his head and sighed repeatedly, then waved his hand at Qi Yuan, signaling him to hurry up and go to work, while he walked to the two old men, squatted down and gently patted them on the back.

Cao Mingyang, his younger brother and Sister Xun also reacted one after another, moved to the side of the two old men, and also sat on the ground, softly relieved.

As they spoke, the four of them couldn't help but huddle, cry together, and sit in the hospital corridor like this.

Xun Mu pursed his lips, sighed lightly, don't look over.

……

At the same time, the physician's office.

Su Ping walked over slowly, walked to the old director's desk, and asked, "What's wrong?" ”

"When I was giving first aid to the patient, I found that he had not obvious symptoms of cyanosis and jaundice, and there was a slight metallic smell in his mouth and nose," the old director said softly.

"From this, I suspect that he may be poisoned by metal compounds, and it is difficult to say whether it is a heavy metal, but most of the ones that can cause acute poisoning belong to heavy metals, and I think it should be almost the same."

After a pause, he continued: "Nothing else, just wanted to see if I could give you some clues." In addition, the blood has also been sent to the laboratory department, and it is estimated that the results will be available soon.

Although your public security forensic doctors can also find out this, I think it will be very helpful for you to be able to determine the cause of death and poisoning as soon as possible. ”

"Indeed." Su Ping nodded and said softly, "This clue is very useful, thank you." However, rather than identifying the type of poison, the murderer's method of poisoning is also crucial. ”

"Judging from the manifestations of his poisoning, the first problem was the digestive system, indicating that it was likely to be poisoned by oral administration." The old director has a lot of experience in this area, although the research direction is slightly different from forensics, but he can also say anything.

But after speaking, he sighed again and said: "But most metal poisoning, if it is taken orally, most of the oral mucosa will have relatively obvious symptoms, especially heavy metals.

Because heavy metals can irreversibly change the structure of proteins, thereby affecting the function of tissue cells, and the oral mucosa is relatively fragile, theoretically speaking......

But I also saw it when I did CPR for him, although the oral mucosa was damaged, but it was basically caused by beating, but I didn't find typical and obvious poisoning symptoms, which is very strange. ”

Su Ping pondered, and after a moment of silence, he said: "Judging from the results of the examination when he was admitted to the hospital, there were no signs of metal poisoning at that time. In addition, we have just done a preliminary investigation and found that after he was hospitalized, he was transferred to the ward, and there were no other unrelated people in the ward. ”

"Oh?" The old director was stunned for a moment and said, "This is very strange......

Moreover, from the onset of his illness to his death, the course of the disease was too short, and the onset of the disease was extremely fast, indicating that the amount of poisoning should be quite large, and the poison itself was also acute, and it was speculated that it should be poisoned within ten to fifteen minutes before the appearance of obvious symptoms, or even shorter.

If no one has ever entered the ward...... Could it be that the person who was already in the ward was poisoned? But I remember that there was only an old man with diabetic foot in that ward, and his son taking care of him. ”

"Well, that's right." Su Ping bowed, thought for a while, and said, "I'll do another investigation, and by the way, go to the security department to extract the monitoring and take a look." ”

"Okay." The old director bowed his head and called Su Ping to come over, just to tell him his guesses, and he said everything that should be said at this time, so he directly signaled him to take it easy.

……

Twenty minutes later, Yan Zhongxin and others arrived at the armed police detachment, and at the same time, the test results also came out, and hexavalent chromium ions were detected in his blood, and the blood concentration far exceeded the lethal amount, that is, chromium metal poisoning.

Xun Mu looked at Cao Mingyang's family members, looking at their grief-stricken appearance, and felt very uncomfortable.

"We're all at odds." At this time, Su Ping returned to the ward, looked at the people who were busy with Yan Zhongxin and Chai Ningning, and slowly walked to Xun Mu's side, and called Qi Yuan over, and then sighed lightly and said:

"They're not talking about any principles at all, they're not having any concerns, they're ...... A more direct, higher-level provocation stepped directly on our heads, poisoned Cao Mingyang in the hospital in front of us, and directly swollen our faces. ”

"yes." Xun Mu's eyes were a little confused, and he didn't know what he was thinking, so he just answered: "This gang of bandits...... Rampant! ”
