A woman who has not graduated from primary school and spends her time playing mahjong with a bunch of old men and ladies is less likely to be exposed to highly toxic chemicals.

What if you have a motive for committing the crime, you can't produce evidence, let alone wronged a good person.

Secretary Zong didn't say anything more, looked back at Han Bo with an expressionless face, and motioned to Deputy Director Yang to continue. Deputy Director Yang named him, and the forensic doctor of the technical squadron reported.

"Report to the leaders, at 2:13 p.m., we and the chief of the history section of the city bureau conducted an autopsy on the bodies of the four deceased in the second hospital of the city, the four bodies were dissected half an hour ago, no obvious external injuries were found on the corpses of the four corpses, and no fractures were found, we can only extract heart blood, urine, stomach contents and liver tissue for the time being, and the test results may take a few days to come out. ”

The medical examiner opened the folder, took out a stack of medical records and test sheets, and continued: "Since the four deceased died in the hospital, we still have a lot of information, and the medical records show that the four deceased were brought to the hospital with unsteady standing, severe headache, chest tightness, difficulty breathing, decreased vision and hearing, increased heart rate, arrhythmia, decreased blood pressure, dilated pupils, and convulsions.

Hospital tests found high levels of cyanide in their plasma, thiocyanate in their blood and urine, and a reduced oxygen difference in arteriovenous blood. The medical staff recalled that when the patient first arrived, the exhaled breath had a bitter almond taste, and there were symptoms of irritation of the mucous membranes of the eyes, pharynx, and upper respiratory tract, followed by vomiting and tremor, accompanied by gradually worsening systemic symptoms. ”

Bitter almond flavor!

It was a key word, reminiscent of the open windows of the deceased's house, and Han Bo frowned.

Most of the people present did not know these symptoms and what it meant for the deceased to exhale the "bitter almond flavor" before his death, and they seemed a little impatient, feeling that the old problems of forensic doctors had been committed again.

The medical examiner didn't know what others thought, looked at the medical records, and continued: "When I was first sent to the hospital, I was still conscious, my eyes and pharynx were congested, my blood pressure was high, my breathing was deep and fast, my tendon reflexes were often hyperactive, and there were no pathological reflexes, but this process was very short, and after less than half an hour, their breathing became difficult, and the skin and mucous membranes were cherry red, showing extreme dyspnea and rhythm disorders. ”

The cherry red color of the skin and mucous membranes is another keyword!

Han Bo subconsciously recorded it in his notebook, his brows furrowed even tighter.

Immediately afterward, blood pressure rises, pulse rate increases, pupils dilate, eyes bulge, cold sweat is dripping, and the patient often has a sense of terror. The elderly and children lose consciousness first, and there are tonic and paroxysmal convulsions one after another, and the children even have angular arch reflexion, shallow and irregular breathing, cyanosis, slow and weak heartbeat, decreased blood pressure, incontinence, pulmonary edema and respiratory failure.

After they fall into a deep coma, the general spasms stop, the muscles relax, the reflexes disappear, the blood pressure drops significantly, the pulse is weak and irregular, and the breathing is shallow, slow and irregular, and then stops. According to the rescue records, the heartbeat lasted for two or three minutes after the breathing stopped, and then the heartbeat stopped and died. ”

Finally finished speaking, Deputy Director Yang couldn't help but ask: "Lao Huang, what can these situations mean?"

Without waiting for the old forensic doctor to speak, Han Bo suddenly raised his head: "Comrade Huang, what is the last color of the skin and mucous membranes of the four deceased?"

The old forensic doctor was stunned for a moment, and subconsciously replied: "The skin and mucous membranes began to look peach-colored, and then gradually turned to cyanosis. ”

"Prodromal phase, dyspnea phase, spasmodic phase, paralysis phase, typical symptoms of severe cyanide-hydrogen poisoning. ”

He could only determine that it was cyanide-chemical poisoning, and he actually pointed out that it was very likely to be cyanide-hydrogen. It turned out to be a peer, and it was a very high-level peer!

The old forensic doctor asked excitedly: "Han Chu, you are also a forensic doctor?"

"I'm not a forensic doctor, I've just studied similar cases. ”

Han Bo looked back at Secretary Zong and the Wang detachment, and asked, "Comrade Lao Huang, what first aid measures have been taken by the Second Municipal Hospital?"

"At the smell of bitter almonds, the director of the emergency room suspected that it was cyanide-chemical poisoning and immediately took the right medicine, took off the four deceased, no, the patients at the time, took off their clothes and washed their potentially contaminated skin. Considering that it may be ingested by the digestive tract, gastric lavage is carried out immediately, while the antidote is applied locally. ”

Judging from the situation introduced by the old forensic doctor, the doctor is experienced and very competent, and promptly adopts the "sodium nitrite sodium thiosulfate" therapy, wraps isoamyl nitrite in gauze and breaks it, inhales it to the patient, repeats 1 stick every 3 minutes, and uses a total of 6 sticks until sodium nitrite is used.

Then slow intravenous injection of sodium nitrite, and the use of cystine, cysteine, glutathione and thioethanolamine have a certain detoxification effect, which can provide a small amount of sulfur combined with cyanide ions in the patient's body to form thiocyanate excretion drugs.

Respiratory failure, cardiac arrest, immediately treated with cardiac resuscitation.

However, the doctor is a human being, not a god, and can only treat the disease but not save the life, and the four patients are severely poisoned, and the medical staff are powerless, so they can only watch them die after rescue is ineffective.

Secretary Zong just wanted to solve the case, and was not interested in these, so he asked eagerly: "Han Chu, are you saying that the four deceased died of cyanide-chemical-hydrogen poisoning?"

"Most likely cyanide-hydrogen, or other cyanide-chemicals. ”

"What does cyanide-hydrogen look like?"

Han Bo studied chemistry and explained: "Cyanide-hydrogen-is a liquid in the standard state, which is easy to disperse evenly in the air and can be burned in the air. Cyanide-hydrogen is explosive when the content in the air reaches 5.6% to 12.8%, and it is a highly toxic chemical.

The clinical manifestations of acute cyanide-chemical-hydrogen poisoning are the same as those just described by Comrade Lao Huang, the patient's exhaled breath will have an obvious bitter almond taste, and the mild poisoning is mainly manifested as chest tightness, palpitations, increased heart rate, headache, nausea, vomiting, and blurred vision. Severe poisoning is mainly manifested by a deep coma, shallow and rapid breathing, paroxysmal convulsions, and even tonic spasms. During World War II, the Nazis often used cyanide-chemical-hydrogen as homicidal gas in the gas chambers. ”

The Wang detachment felt a pang in his heart, and when he watched the scene in the afternoon, Han Bo mentioned that the possibility of poison gas killing could not be ruled out.

Poison gas is not gas, not everyone can buy it, I really didn't take it seriously at the time.

Although the results of the forensic pathological examination will not be available for a while, judging from the rescue records and laboratory tests provided by the Second Municipal Hospital, it is almost 100% certain that cyanide-chemical poisoning is very likely, and it is very likely that cyanide-chemical poisoning is very likely.

Cyanide-hydrogen, in its standard state, is a liquid that volatilizes once exposed to the air, and becomes a murderous gas that permeates the air. If the murderer had changed his target and had done it again in a densely populated area, what casualties would it cause!

The problem was more serious than imagined, the more the Wang detachment thought about it, the more worried they became, took out their mobile phones and were about to report to the leaders of the city bureau, when Deputy Director Yang Guosheng's mobile phone rang.

"Hey, say, what, say it again, is it possible to make a mistake...... is definitely not good news, Yang Guosheng's face became more and more gloomy.

"Lao Yang, what's the situation, what's going on?" shouldn't there be a second incident, Secretary Zong chuckled in his heart.

"The comrades of the Zong Bureau, the Han Division, the Wang Detachment, and the Criminal Technology Center of the Municipal Bureau reported the results of the vomit test, and the test results came out, and no poisonous drugs such as pesticides, highly toxic rat poison, and cyanide chemicals were detected in the vomit of the deceased. ”

"It's okay to eat something, what you drink is not poisonous, it's not ingested by the digestive tract?"

"If the test results are correct, the cause of death of the four deceased people has been guessed by Han, who have inhaled toxic gases. There are more than 600 households in a community, and thousands of people live there, and other people's families are fine, but their family is in trouble, and then think of the windows of his house, what does this mean, and it shows that this is a premeditated poison gas murder case. ”

Realizing the seriousness of the problem, Secretary Zong asked with a gloomy face, "Is it possible that it was inhaled somewhere else?"

"We inquired at the scene, and the residents of the community and the security guards of the community confirmed that the elderly among the four deceased hardly went downstairs or went out because they suffered from severe lumbar disc herniation and bone hyperplasia, back pain and leg pain. ”

If it is inhaled somewhere else, the old man will not be fine!

Remembering what Han Bo said in the afternoon, Deputy Director Yang Guosheng added: "The chemical plant has moved out of the city early, and the road in front of the community is restricted. ”

"Investigate, investigate the social relations of the deceased, investigate the chemical enterprises in the city, trace the source of cyanide-chemical-substance, and continue to interrogate Fu Liqing. ”

The murder of four people, and the poisoning case with a very serious nature and a very bad impact, is not something that the sub-bureau can handle. In the case of Nangang, as long as poisoning and arson are involved, as long as there are casualties, no matter how many dead or injured there are, the criminal police detachment will take over as soon as possible.

Han Bo would like to suggest that the criminal investigation detachment of the city bureau should be in charge, but now it is only guiding the investigation and can only fill in the gaps, and cannot interfere with the jurisdiction of the public security organs at the city and district levels over the case.

Just thinking about it, Wang Xinlei, the head of the detachment, suddenly said: "Secretary Zong, the matter is very important, we had better report to the leaders of the bureau immediately, and it is best for the city bureau to take over this case." ”

There is no love for no reason in the world, and there is no hate for no reason, if there is no enmity with Tan Xingtao and Tan Xingtao's second wife, who will do this?

The social relationship of Tan Xingtao's family is complicated, but it is not so complicated that it cannot be investigated, and it stands to reason that it is not difficult to solve this case.

But if you are not afraid of 10,000, you are afraid of what happens.

In case the murderer had no enmity with him before, but he found out that he was very rich, wanted to poison his family and then burglarized, it had nothing to do with his former brother-in-law Fu Liqing, Fu Liqing just happened to meet him, then how to solve such a headless case.

This case is a bit tricky, and this skill is not easy to grab.

Secretary Zong weighed it and agreed: "It's okay, do you report first or I report first?"

"The case happened in the precinct of the sub-bureau, you go first. ”
