"Yes, the prescription and the herbs in the medicinal diet are bought from the old Chinese medicine doctor, not far from here, just east of the main street, Jishi Chinese Medicine Museum, many people in our village go to him to grab Chinese medicine, I have tried that recipe before, yesterday I also ate a pot of stewed mutton with a perfect tonic soup, my family and I are fine, why do you do the same today, the customer in the store has an accident...... Comrade policeman and comrade doctor, it shouldn't be because of this soup, right? Alas...... If it weren't for this great tonic soup, what would it be? I'm so unlucky......"

The restaurateur nervously began to talk to himself again.

As he spoke, the forensic doctor had already carried the body out and was ready to transport it back to the forensic center for further autopsy.

Nan Hanfei answered another phone call, hung up the phone and said to the members of the police force who were about to leave, "I have to go to another scene, someone reported the crime, and a deceased person was found in the workers' dormitory of the construction real estate community not far from here." ”

The police force left, and only the CDC team and the restaurant owner were left in the small restaurant.

Gu Yanan instructed the emergency team members to sample the remaining food in the restaurant, and Lu Li also focused on collecting the food in the back kitchen, especially the Chinese herbal tablets in the condiments.

Gu Yanan looked around the deceased's table and found that there were large pieces of vomit around the deceased's shape marked by the police at the time of death, which were all undigested food residues that had just been eaten into the stomach.

Food residues interact with gastric juices, giving off a sour smell and a strong smell of alcohol.

It seems that the deceased had drunk a lot of alcohol before his death.

Gu Yanan subconsciously looked up at the table where the deceased had eaten before his death, and the leftovers on the table remained the same.

I ate most of the mutton soup, two and a half pots of rice, a table full of rice grains, half a plate of peanuts and a plate of shredded potatoes, as well as 6 wine glasses and a plastic bucket of bulk wine.

There were still remnants of leftover liquor in the 6 glasses, not a clear liquor, but a brown color, like medicinal wine.

Gu Yanan approached the wine glass and fanned the mouth of the glass with his hand, and a strong smell of wine came to his face, with the smell of grass and trees in the wine.

Sure enough, it's medicinal wine.

Gu Yanan pointed to the wine glass on the table and asked the restaurant owner, "Are these medicinal wines from your store?" ”

The restaurateur shook his head, "No, my restaurant only sells finished wine, not bulk wine, nor medicinal wine, their wine is brought by themselves, not from our restaurant." ”

At this time, Mr. Zhou called from the First People's Hospital to report the situation: "There are 5 people with serious symptoms in the hospital now, according to the doctors who participated in the on-site emergency at that time, these 5 people sat at the same table as the deceased, and the others had mild symptoms, and they were all guests who dined at other tables in the restaurant......

Gu Yanan listened to the phone while looking at the table next door, where the Ten Perfect Tonic Soup had all been eaten, judging from the number of chairs, there were only 4 guests at the next table, and the 6 people at the table where the deceased was, the total amount of the Ten Great Tonic Mutton Soup was the same, according to the amount of food eaten by each person, the symptoms of the 4 people at the next table should be more serious, but in fact, the symptoms of the 6 people at the table were severe, and there were deaths, which showed that the poisoning was related to the Ten Perfect Tonic Soup, but it was not completely positively correlated.

The medicinal liquor on the table of 6 people may also be one of the sources of poison.

Gu Yanan opened the sampling box and put the remaining medicinal wine on the table into the sampling bottle.

If there is a problem with these medicinal wines, then people who have drunk them may experience symptoms of poisoning, and it is necessary to find the source of the medicinal wines.

Gu Yanan asked the restaurant owner, "Do you know where the medicinal wine on this table comes from?" ”

The restaurant owner thought for a while and analyzed: "When I was serving, I heard the guests at this table say that their wine was bought on the street, and there is only one restaurant that sells medicinal wine on our street, not far from here, called Xiaomengyan Hotel." ”

After doing the flow adjustment in the restaurant, Gu Yanan decided to go to this place called Xiaomengyan Hotel to have a look, take samples for inspection, and remind them in time if there is really a problem with the medicine and wine there.

Coming out of the restaurant, Gu Yanan followed the tips of the restaurant owner and walked more than 50 meters east to find the smoke hotel, but the smoke hotel was closed.

Gu Yanan stepped forward and knocked on the door, knocked a few times and no one responded, and suddenly a middle-aged man appeared next to him.

The middle-aged man looked at Gu Yanan, saw that he was wearing a CDC uniform, and asked, "What are you going to do?" ”

Gu Yanan recognized that the middle-aged man in front of him had just appeared in the crowd of onlookers near the restaurant where the accident occurred, "You are the owner of this cigarette hotel?" ”

The middle-aged man was stunned for a moment, and then shook his head, "No, the boss is out, he should come back tomorrow, if you want to buy wine, you should come early tomorrow morning, you see it's so late, everyone must be asleep." ”

CDC is not the police, and private homes cannot be searched at will without special circumstances.

There is no evidence to prove that there is a problem with the medicine and liquor in this tobacco hotel, and it is not possible to trespass into private houses, so Gu Yanan decided to take the samples collected from the restaurant back to the CDC first, and wait for the test results to come back here tomorrow for a second investigation.

22:50 on the same night.

Lianhai Center for Disease Control and Prevention, Laboratory.

Samples collected from the problematic restaurant in Mengzu Village, samples from poisoned patients collected from the city's First People's Hospital, and samples of the deceased sent by the forensic medical center were all sent to the laboratory for poison testing.

Because of the previous diagnosis by a clinician, aconitine poisoning was suspected, so the focus of the laboratory was aconitine.

The samples were sent to the physicochemical group, and the results came back a few hours later.

Before dawn on the second day, Gu Yanan received a test report from the laboratory.

Different levels of aconitine were detected in body fluid samples from hospital patients, as well as from deceased people.

Aconitine was detected in the mutton soup in the back kitchen of the problem restaurant in Mengzu Village, and the content was about 10 micrograms per milliliter in the soup of several tables.

Aconitine was detected in the medicinal liquor on the table where the deceased was located, with a very high level of 810 micrograms per milliliter.

The content of aconitine in medicinal wine is more than 80 times that of aconitine in Shiquan Tonic Soup.

Sure enough, as Gu Yanan speculated, there was a problem with the Ten Perfection Tonic Soup, and there was even more problem with the medicinal wine.

The problem medicine and wine are the key targets of investigation.

Before dawn, Gu Yanan had already gotten up and started to pack up his things, preparing to go to Mengzu Village for the second time, this time he wanted to check the Xiaomengyan Hotel, which sold problematic medicine and wine.

——

6:20 a.m.

The western suburb of Lianhai City, Mengzu Village.

It was just dawn, and there were no pedestrians on the main street of Mengzu Village.

Gu Yanan drove the on-site flow shunting car and stopped at the intersection of the main street alone, to Gu Yanan's surprise, there was another car parked at the intersection of the main street, which was the license plate number she was familiar with, and Nan Hanfei's car was also parked here.

After getting out of the car, Gu Yanan carried the sampling box along the main street all the way to the Little Mengyan Hotel.

Most of the shops on Main Street are not open, but the Little Dream Smoke Hotel is open.
