In the office of the Criminal Police Team of the Meihai City Public Security Bureau, everyone sat around the whiteboard.
Except for the information about the case of Qu Hailong and his wife, the rest of the information on the whiteboard is all about Liang Nan.
Liang Nan, male, 29 years old, unmarried, from Meihai City, came back from the United States two years ago and works as an attending physician in the child psychology department of Anxin Children's Hospital.
After introducing Liang Nan's current situation, Sun Xiaokai continued: "When Liang Nan was 7 years old, his mother poisoned the food and poisoned his father and grandparents. Liang Nan and his mother were saved because of timely rescue. Come down.
According to the investigation at the time, Liang Nan's mother had been abused by her father for a long time, and Liang Nan's grandparents ignored her. His mother only poisoned her when she was desperate. Her idea at the time was to die together as a family.
This case was very sensational at the time. Affected by Liang Nan's father's relatives and public opinion, Liang Nan's mother was sentenced to death. "
After hearing about Liang Nan's past, Bai Mo slowly looked at Lu Wan, but unfortunately Lu Wan didn't look at him.
Liang Nan's experience is very similar to Teng Jie's new book "The Last Supper". Bai Mo even suspected that Liang Nan's case was the prototype of that book.
Chen Xiaoxiao said: “The family environment leads to psychological abnormalities. He hates parents who affect the healthy growth of their children, such as Jamie. He is worried that Jamie will be like him one day in the future, so in order to save Jamie, he killed Jamie’s parents! "
"It can be explained this way." Zeng Hao agreed. Everyone has been studying criminal psychology this month, and Liang Nan's situation has many similarities with the cases they have seen.
Bai Mo nodded, "Yeah! He feels that saving Jamie is saving himself back then. He was extreme and stubborn. Why does he feel like a serial killer?"
"Maybe he is a serial killer!" Sun Xiaokai said.
Upon hearing this, everyone looked at Sun Xiaokai at the same time.
Sun Xiaokai pulled up a file on the big screen, which was about a car accident that happened half a year ago.
The car accident occurred on a winding mountain road in the west of Meihai City. A couple's car rushed off the mountain road and they died on the spot.
The male deceased was named Wang Chuanxing, and the female deceased was named Jiang Yuelei.
Wang Chuanxing and his wife were visiting a resort in the mountains, and a car accident occurred when they were going down the mountain the next night.
The traffic police inspected the scene and found that there was nothing wrong with Wang Chuanxing's car. The place where his car ran out of the mountain road was a very narrow corner.
Based on the experience of the traffic police, they believed that Wang Chuanxing found something blocking the mountain road when he was cornering. He instinctively turned to the right and used too much force, causing the car to run off the mountain road.
"Actually, there were doubts at the time." Sun Xiaokai said, "There had been a car accident on that narrow curve before, so the municipal government reinforced the guardrail on the curve. It stands to reason that unless the car is traveling at high speed, it cannot hit the guardrail. of."
"That's right!" Lu Wan said, "That's a mountain road. Any driver will slow down when turning. Since there are doubts, why didn't the traffic police hand over the case to our criminal police team?"
Sun Xiaokai sighed, "Because the alcohol content in Wang Chuanxing's body seriously exceeded the standard! According to the traffic police who investigated the scene at the time, Wang Chuanxing's car was full of the smell of alcohol, and he was definitely driving drunk."
When she heard that Wang Chuanxing was driving drunk, Lu Wan didn't know how to evaluate it. In this case, many conjectures would be overturned. It's no wonder that he was not handed over to the criminal police team at that time.
"What does this case have to do with Liang Nan?" Bai Mo asked, getting to the point.
Sun Xiaokai snapped his fingers, and the big screen cut into a picture of a boy.
"His name is Wang Doudou. He is 7 years old this year. He is the son of Wang Chuanxing and Jiang Yuelei. He suffers from severe autism. He has medical records at Anxin Children's Hospital. Their attending physician is Liang Nan!" Sun Xiaokai said.
Many people took a breath. They all believed that the death of Wang Chuanxing and his wife was related to Liang Nan.
Sun Xiaokai continued: "I checked Wang Chuanxing's reservation information at the resort. He was not supposed to check out until the third day. I checked his call records and found that he received a call on the night of the incident. After answering the call, he I left the resort. That number is a black account, and the head of the household cannot be traced at all."
This is a consequentialist approach. According to Lu Wan's request, Sun Xiaokai investigated all the patients and patients' families related to Liang Nan, and then discovered Wang Chuanxing and his wife.
Precisely because Wang Chuanxing and his wife were related to Liang Nan, Sun Xiaokai re-investigated the car accident of Wang Chuanxing and his wife in the same way as a murder case.
Lu Wan crossed her arms and leaned on the seat, tapping her fingers regularly on her elbows.
Seeing that Lu Wan didn't speak, Bai Mo asked, "Can we investigate Liang Nan's alibi?"
Chen Xiaoxiao shook his head, "Even if he can't provide an alibi, we can't convict him. The current motive is what we inferred, and this inference cannot be used as direct evidence in court."
"What should we do?" Bai Mo yelled angrily.
Bai Mo does not have a deep understanding of the handling process of criminal cases. He has not yet fully understood what a closed chain of evidence is.
Zai Bai Mo thought that all he needed to do was determine who the murderer was and bring him over for interrogation.
Just like Lu Yajun before, didn't he still reveal his true colors under Bai Mo's portrait?
"Liang Nan is not Lu Yajun!" Lu Wan seemed to see Bai Mo's thoughts. She patiently explained, "Liang Nan is a graduate student and has received a complete education. From today's questioning, it can be seen that his logical thinking is quite rigorous. .
I suspect he was the one who committed the murder! Whether it was the death of Wang Chuanxing and his wife, or the death of Qu Hailong and his wife, they all reflected his almost perfect murder plan. At least until now, we have not obtained any evidence pointing to him. "
Lu Wan closed her eyes and recalled her contact with Liang Nan, "This man has a plan and did not panic in the face of our sudden investigation. He is an extremely conceited criminal! Fortunately, I did not alert him today and make him mistakenly I thought we were still investigating in the direction of hiring a murderer."
Bai Mo understood what Lu Wan meant, and he asked tentatively: "Liant Lu, do you mean that he may continue to commit crimes?"
Chen Xiaoxiao showed a worried look, "According to the current profile, he is very planned and avoids all risks as much as possible. I think he is likely to stop temporarily. If he is smart enough, he might borrow Po Xia Donkey, thinking that we were investigating in the direction of hiring murderers, why did you simply stop?"
"No!" Lu Wan's answer was firm, "Definitely not!"
Feeling the curious eyes of everyone, Lu Wan smiled coldly, "Because he suddenly realized that what he was doing was right, so in order to let his approach affect more people, he will definitely continue!"
