At two o'clock in the morning, a group of girls with high emotions were about to get the man in front of them drunk, but what they didn't expect was that the man had not drunk a few glasses, but he vomited blood directly and died on the sofa.

The police quickly arrived at the scene after receiving the report, and this is the third sudden death in public today.

All three of the deceased had fever, hemorrhage and respiratory failure before their sudden death.

The deceased in front of him was named Zhang Xiaohui, 22 years old, and according to eyewitnesses, the man had convulsions before he fell.

There were two suspected symptomatic deceased people, one was Zhao Wuguang, 48 years old, and his family said that he had been bitten by a wild cat yesterday, and he also had a high fever before his sudden death, and unfortunately died an hour after being admitted to the hospital.

The other deceased, Huang Xingjun, a 20-year-old young man, died on the way to the hospital on 120 with the same symptoms.

The medical examiner carefully examined Zhang Xiaohui's body, and to his surprise, the deceased's face was marked with cyanotic corpse spots, and his joints were relatively stiff, and this sign was not like it could be formed in such a short time of death.

Upon returning to the police station, the medical examiner examined the three bodies separately and found that the organs of the three deceased were in a state of rapid failure, which was very similar to the stimulation of poison.

Then the forensic doctor took the deceased's blood and liver slices and sent them to the laboratory for examination, and went out of the autopsy room, and the forensic doctor told Lao Ji about the autopsy.

After hearing this, Lao Ji guessed that this might be a serial poisoning case, but Sister Xi expressed great doubts, if someone deliberately poisoned him, how did the murderer commit the crime in a short period of time and in multiple places.

And the identities of the three deceased have nothing to do with each other, so what is the purpose of the murderer's poisoning.

Later, they came to the office of the special case team, where Lao Ji told everyone the basic information of the three deceased, and instructed the team members to immediately investigate the social relations of the three deceased, and strive to find out the relationship between the three cases.

Xiao He and Ah Qiang found the residence of the deceased Zhao Wuguang, and his wife immediately changed her face after seeing the police, and closed the door directly with the intention of turning the two away.

After knocking on the door again, his mother opened the door, and the old man was convinced that his son had been bitten by a wild cat and died, but when Xiao He told her that Zhao Wuguang might have died from poisoning, his wife suddenly seemed a little flustered.

Lao Ji took his colleagues to Huang Xingjun's house, and when he entered his bedroom, he found takeaway boxes and drink bottles everywhere.

learned from his roommate that Huang Xingjun is completely an otaku, usually playing games in the house, and the farthest way is to go to the express station downstairs.

Lao Ji looked at a room full of fast food boxes, and it seemed that he could only start from these things.

At the same time, Sister Xi came to the school to find the female classmate who was at KTV with Zhang Xiaohui that night, and the female classmate said that Zhang Xiaohui had a strange habit, that is, he had to drink a cup of coffee before drinking every time, which he said could make him sober.

Then Sister Xi came to Zhang Xiaohui's house again, but she happened to meet his father who was surrounded by a group of creditors to collect debts, Sister Xi walked in and asked what happened, and the debt collector took out Zhang Xiaohui's IOU to show Sister Xi.

Sister Xi warned them to stop this kind of debt collection behavior, and after sending away the gangsters, Sister Xi learned from Zhang Xiaohui's father that Zhang Xiaohui was a complete loser, who was addicted to Dbo's huge debts outside and lost all the family's previous belongings.

Today, more than one wave of people have come here to collect debts, and everything that can be taken by the family has been taken.

When Xiao He and Ah Qiang left Zhao Wuguang's community, they met an aunt, who said that Zhao Wuguang had done a lot of evil and suffered retribution. Because he beat his mother twice for three days, his wife has lived with him for so many years, and he has been wronged.

Xiao He and the others then came to Zhao Wuguang's unit, and the leader of the canteen told them that Zhao Wuguang was usually very particular about eating, and he had to ask his daughter-in-law to come over to deliver food every day, and he usually only used his own cup to drink water.

After listening to Xiao He asked where the lunch box and cup he usually ate were, the leader took them to the back door next to the trash can, and the two had to take out their gloves to prepare for work for the case.

Back at the police station in the evening, Lao Ji brought back a bunch of Huang Xingjun's lunch boxes and drink bottles.

Xiao He and Ah Qiang also brought back Zhao Wuguang's lunch scraps that day.

Unexpectedly, after the laboratory examined these things, a poison called colchicine was found in the food of the two deceased.

Sister Xi told Lao Ji that colchicine is a relatively bitter poison, and a small amount of colchicine will not poison people, but a large amount of colchicine needs to be synthesized by pharmaceutical factories or chemical institutions to get it.

The poison, when diluted, is mostly used to relieve the symptoms of gout and cancer patients, and it is not noticeable when placed in coffee and tea.
