Gu Yanan said to Wang Xiaoxiao and Gao Fei, who were following behind, "Put this glass box and the armadillo inside into a bag and take it back." ”

Zhang Zixin's parents saw that the disease control personnel were going to take away the little pet in their daughter's room, and hurriedly stepped forward to stop it, "This is what my daughter left, do you want to take it away?" ”

Gu Yanan: "Armadillos can transmit leprosy, and we suspect that this is related to your daughter's leprosy infection before her death, so we should take her back for testing." ”

Although Zhang Zixin's parents were reluctant, they no longer stopped in order to find out the truth.

Gu Yanan then asked Zhang Zixin's parents, "Armadillos are an endangered species and rarely appear in my country, I want to know when Zhang Zixin was and how he brought them home as pets?" ”

Zhang Zixin's father replied, "Zixin went to the United States half a year ago, and when she came back, she brought back this armored mouse. ”

Without waiting for Gu Yanan to ask again, Lu Li suddenly asked: "Animals must go through strict quarantine when they enter the country, how did Zhang Zixin bring this little animal back?" ”

Zhang Zixin's father glanced at Lu Li, then at the police and disease control staff beside him, and didn't notice anything unusual, and then replied: "When Zixin came back, she said that when she got on the plane, she was strictly inspected, so she wore a loose dress, hid the little armor rat in her sleeve, and came back in a fool. ”

From this point of view, this pet pink fairy armadillo was smuggled back by Zhang Zixin and has not been quarantined, so it is even more suspicious.

Before leaving, Nan Hanfei told Gu Yanan, "After you have the test results, tell our police, this may be related to the clues to solve the case." ”

Gu Yanan made an OK gesture, "No problem, I'll call you as soon as the results come out." ”

Lianhai Center for Disease Control and Prevention, Laboratory.

Lu Li and Wang Xiaoxiao were busy in the laboratory, first collecting blood from the pink fairy armadillo, and then taking the specimens collected from Zhang Zixin's home and the blood samples of Zhang Zixin's parents together for leprosy bacillus testing and PCR confirmation experiments.

The results of the experiment came out quickly, and the pink fairy armadillo detected Mycobacterium leprae in his body, and everything else was normal.

Lu Li showed the experiment report to Gu Yanan.

Gu Yanan analyzed that from the experimental results, the leprosy bacteria in Zhang Zixin's body were infected from her pet pink fairy armadillo.

The pink fairy armadillo was brought back by Zhang Zixin privately when he was traveling in the United States, so that the closed transmission chain of infectious diseases was formed.

Did Zhang Zixin transmit Mycobacterium leprae to others?

Could Zhang Zixin's death be related to her leprosy?

Will this clue help solve the murder and dismemberment case?

Gu Yanan was thinking about various possibilities in her heart, and Lu Li, who was standing beside her, looked at Gu Yanan's brows frowning slightly, and asked a little anxiously: "Director Gu, will our test results help the police solve the case?" ”

"I don't know, I'll tell the police the results now, but don't get your hopes up, a sporadic case of leprosy doesn't mean anything."

Lianhai Center for Disease Control and Prevention, Emergency Office.

Early the next morning, as soon as Gu Yanan walked into the door of the emergency office of the CDC, Lu Li hurriedly ran over, holding a mobile phone in his hand, and there was a bloody picture on the screen.

Lu Li put the mobile phone screen in front of Gu Yanan, and said hurriedly: "Sister Yanan, look, there is another murder and dismemberment case!" ”

Gu Yanan took the phone and flipped the phone screen.

It turned out that at five o'clock this morning, someone went to the youth park for morning exercises, and found a black plastic bag in the woods.

At that time, someone took a photo with a mobile phone and uploaded it to the Internet, and various comments have exploded on the Internet.

There were two cases of murder and dismemberment of corpses one after another, one of which was dumped in Huxin Park, and the other was in Youth Park, and the two parks were not far apart, and for a time nearby residents panicked.

Lu Li asked cautiously: "Sister Yanan, you said that the interval between these two murders and dismemberment cases is so short, could it be the same person?" ”

"There is such a possibility, but it still depends on the investigation of the police."

Lu Li waited for Gu Yanan's words, and watched Gu Yanan call Nan Hanfei with a blank eye.

Gu Yanan returned the mobile phone to Lu Li, and after that, she used her own mobile phone to call Nan Hanfei, "What is the situation of the other murder and dismemberment case this morning?" ”

Nan Hanfei on the other end of the phone seemed to be very noisy, Nan Hanfei complained in the mobile phone: "Now the network is too developed, netizens know the news earlier than the police know, I am still at the scene of the crime in Youth Park, but this place has been almost destroyed by the crowd of onlookers in the morning, there are no valuable clues, I will not tell you in detail, when I want you to help, I will call you." ”

On the phone, Gu Yanan didn't ask for any useful news, so he could only shrug his shoulders at Lu Li and comforted: "Don't worry, as long as it is a criminal, there will always be clues, and the police will solve the case, just wait for the news." ”

All morning, Lu Li was absent-minded in doing things, and when it was almost noon, Gu Yanan's mobile phone suddenly rang.

Caller ID Nan Han Fei.

Nan Hanfei said anxiously on his mobile phone: "The body parts found in the Youth Park this morning, the forensic doctors of our police force detected mycobacteria from it, and I want your disease control system to confirm whether it is Mycobacterium leprae, and to investigate the relevant records of some leprosy patients from your disease control system." ”

"No problem, the specimen was sent first, is there any identity information of the deceased?"

"Yes, the situation this time is the same as the situation in the last Zhang Zixin corpse mutilation case, after the deceased was dismembered, it was wrapped in a black plastic bag, and the body pieces were discarded together with the deceased's clothes, ID cards and other information."

"It's good to have the identity information of the deceased, send me his information, and I will check the CDC epidemic network to see if he is a leprosy patient who has been discovered."

Some of the specimens collected from the corpses were quickly sent to the CDC, and Gu Yanan arranged for Lu Li to conduct a confirmation experiment on Mycobacterium leprae.

The results of the experiment were soon in, and it was confirmed that Mycobacterium leprae had been detected in the corpse parts.

The deceased, who was just discovered today, was another leper.

Gu Yanan entered the epidemic network of the disease control system and searched for the deceased according to the information provided by Nan Hanfei, and the name of the deceased was not found in the information of the leprosy patient.

The deceased was a new leprosy patient.

If it is a coincidence that the first deceased, Zhang Zixin, was mutilated and leprosy, then the deceased in the second mutilation case was a leprosy patient, and there must be some kind of connection between the two.

Gu Yanan felt that something was wrong, and Nan Hanfei felt that there must be some kind of connection, but he couldn't find what the specific connection was, and the case investigation entered a bottleneck.
