Solving the case: The opening scene solved a major shooting case, and the boss Ji Jie

Mai Dong coughed, Luo Fei stood up and poured him a glass of water,"Don't be nervous, talk slowly."

After drinking the water, Mai Dong recalled,"When I went to her house yesterday, she was wearing a suspender skirt and lipstick. When she took the lunch box from me, she seemed to get very close to me intentionally or unintentionally, and said thank you to me."

"Do you think Wang Qi is hinting at you?" Fang Mu asked.

Mai Dong was stunned for a moment, then nodded,"Although I didn't dare to believe it, the way she looked at me was indeed strange, as if she was expecting something. But I have always been very inferior and didn't dare to have other thoughts, let alone dating her. I didn't even have the courage to look her in the eye, so I turned around and left."

""After that, did you go back again?" Luo Fei asked.

Mai Dong nodded,"After I delivered the meal at Huayuan Road, I thought about it and felt unwilling. Since no one disliked me, why should I worry about it? So I ran to the 17 flower shop opposite the Ziguang Community and bought a bouquet of roses. At six o'clock, I returned to the Ziguang Community. What I didn't expect was that many policemen suddenly appeared downstairs of her house, and she was lying on a stretcher covered with a white sheet. She was already dead........."

Maidong covered his face and his voice began to choke.

"I really regret it now. If I had mustered up the courage and confessed to her, maybe everything would be different! Maybe she wouldn't be hurt by others. I'm so useless! It's all my fault. I didn't protect her..........".

Luo Fei handed Mai Dong a tissue and comforted him.

Luo Fei and Fang Mu walked out of the pre-trial room. They both felt that it was very unlikely that Mai Dong committed the crime, but just in case, they went to the flower shop opposite Ziguang Community to check. Dongchang Central Hospital, in the director's office. Song An and Mu Jianyun sat opposite Zeng Yi, the director of the city hospital.

"Dean Zeng, we would like to ask you a question. What kind of patients are very sensitive to blood?"Song An asked. Dean Zeng lowered his head and thought for a while, wiping his glasses, and said,"I don't know what degree of sensitivity you mean. If you are very eager for blood, then it's too much."

Dean Zeng stood up and opened the curtains of the office, and a lot of sunlight poured in from outside.

"For example, leukemia, hemophilia syndrome, and porphyria. Patients with these diseases are very eager for normal blood, especially porphyria, which is what ordinary people often call vampire disease. Patients are particularly eager for normal blood."

Song An and Mu Jianyun looked at each other and said at the same time,"Vampire disease?"

Dean Zeng smiled,"In fact, vampire disease is just a misunderstanding. Porphyria patients lack enzymes involved in hemoglobin metabolism, which leads to a large amount of porphyrin deposition in the body, causing skin lesions. Therefore, patients with this disease must not see the sun!

Once exposed to sunlight, the patient's skin will have large areas of ulceration, scabs, and even heavy bleeding, and the face will be severely damaged. In the end, it is very similar to the image of vampires or zombies in movies and TV dramas, so ordinary people call this disease vampire disease!"

After Dean Zeng finished speaking, he pointed to the TV in the office and said with a smile,"Recently, Hong Kong and Taiwan have been broadcasting movies and TV series such as zombies and vampire dukes, which will have a subtle influence on ordinary people, especially the recent two blood-sucking cases, and the whole city is in a panic."

"Dean Zeng, the porphyria you just mentioned, is it acquired or........"

Before leaving, Song An suddenly asked

"Oh, this disease is usually inherited from family members and is a systemic disease. Generally, patients with this disease will die within two years at most."

"Thank you, Dean Zeng. Your words are very inspiring to us.

Song An shook hands with the other party and came out of the dean's office.

"Song An, I think we should mobilize all the elite forces to immediately screen all the porphyria patients or blood disease patients in the city! Especially those who have systemic blood diseases within three years!"

After hearing Mu Jianyun's suggestion, Song An was a little helpless,"Dongchang is so big, there are so many hospitals, once we all go to screen all the blood disease patients, I am afraid we will not have enough manpower."

"So what do you mean? Even if it's just looking for a needle in a haystack, it's better than doing nothing."Mu Jianyun said unhappily.

"You are a psychology expert, can you make a criminal portrait and give a rough idea of who he is?"

The two talked as they walked and arrived downstairs.

Mu Jianyun was silent for a moment, brushed his long hair behind his shoulders, then raised his head and said,"I can only say that he is around 20-30 years old, about 172 cm tall, has severe social phobia, walks in a trance, dares not look people in the eye, and there must be a strong smell of medicine on his body."

Song An shook his head,"This kind of portrait is of no help in solving the case. There are millions of people in the city, and there are at least thousands or tens of thousands who meet your criteria. You can't search them one by one." Mu

Jianyun has always been arrogant, the kind of person who walks 160 meters with his head held high. He didn't expect to be refuted by Song An like this today. He felt a little unconvinced.

"Song An, you don't understand psychology, so don't make random comments. Criminal psychology is a behavioral science, not a blind guess. There is too little evidence at present, so I can only speculate these."

Mu Jianyun opened the door of the police car and was about to get in, when suddenly, Song An put his hand on the door.

""What are you doing?"

Mu Jianyun rolled his eyes at Song An,"I didn't make a criminal profile, and you won't even let me ride in your car? You stingy guy!"

Song An shook his head,"Listen, there are a lot of sirens nearby, it seems like there's another case!"

Mu Jianyun pricked up his ears, but didn't hear any sirens.

Sister Mu Yu pushed Song An,"What ears do you have? Why didn't I hear anything!"

At this moment, both of their cell phones rang at the same time!

Song An and Mu Jianyun picked up their phones at the same time. Both of them were calling from Dongchang Police Station. The content of the calls was exactly the same, another murder!

"Hurry, get in the car, and go to Jianshe Road!"

As soon as Mu Jianyun got into the passenger seat, Song An didn't wait for her to fasten her seat belt, and stepped on the accelerator, and the police car rushed out like a bullet.
