The crackdown on organized crime began with the arrest of the mother-in-law.

Chapter 768 Footprint Identification and Analysis: Analyzing Suspect Characteristics

The young female victim was named Zhao Lingyu. Compared to her husband, Zhao Lingyu had a more complex work environment and interpersonal relationships. Chen Kai and his team had been focusing their efforts on investigating Zhao Lingyu's social connections.

"Zhao Lingyu is not a native of Nanchuan City, but from Qingzhou. She came to Nanchuan City three years ago. At first, she worked in an electronics factory, and later she worked as a hostess in a business KTV for a period of time."

Following the incident, the investigation into the interpersonal and social relationships of all the victims was a key focus for the Criminal Investigation Division. During the investigation, the investigation into Zhao Lingyu's interpersonal relationships was particularly crucial because she had been sexually assaulted before her murder.

In the process of determining the nature of the case after it occurred, many people in the Criminal Investigation Division had considered whether Zhao Lingyu's interpersonal relationships had a motive or suspicion for the crime. This investigation into Zhao Lingyu's social relationships did indeed reveal that, having worked at a KTV for a period of time, her interpersonal relationships were relatively complex.

Yesterday afternoon, the investigation into Zhao Lingyu's situation was basically completed. Later that night, the investigators worked without rest, and all those involved with Zhao Lingyu were investigated in a short period of time.

In fact, whether it's a criminal case or any other type of case investigation, the police need the cooperation of the other party when investigating the situation of relevant personnel. For example, when investigating whether certain related persons had a motive and time to commit the crime on the day of the incident, it is necessary to conduct investigations and collect evidence from multiple sources. Even if there are some suspicions about the other party, the police will not take any excessive actions without conclusive evidence.

Therefore, the investigation and evidence collection process often takes a long time and cannot be resolved in just one or two days. Some people may be on business trips, in meetings, or unable to cooperate with the police investigation immediately for various reasons. This time, because Qin Chuan demanded that the case be solved within three days, many people were under great pressure. The Criminal Investigation Detachment worked tirelessly to persuade relevant personnel, and by last night, they had met with most of them and had a basic understanding of the situation.

"During our investigation of Zhao Lingyu, we traced her network of relationships involving about 100 people, especially focusing on the period when she worked at the KTV. We found that Zhao Lingyu had two lovers during that time, which is the biggest clue we have found so far."

Zhao Lingyu worked at a KTV for about a year and a half, during which time she saved a considerable amount of money. After leaving the KTV, she went to work at a supermarket as a cashier. She met her current husband about six months ago, and they got married soon after.

However, during the time Zhao Lingyu worked at the business KTV, she had two lovers, and both of them had relatively close contact with her.

"After leaving the business KTV, Zhao Lingyu changed his phone number. We later found information about two people by investigating his previous call records. One of them left Nanchuan City a year ago and has not returned since, which does not match the time of the crime. However, the other person has been in Nanchuan City all along. This person is named Li Guofeng."

The information about Li Guofeng was obtained yesterday afternoon around 7 PM, after which the Criminal Investigation Detachment conducted a detailed investigation into him.

"Li Guofeng is a 42-year-old local from Nanchuan City. He and Zhao Lingyu met two years ago. At that time, Zhao Lingyu was working as a hostess at a business KTV, and Li Guofeng was a regular there. The two even lived together for a period of time."

Li Guofeng was the owner of a chain supermarket. After meeting Zhao Lingyu at a KTV, he had the idea of ​​keeping her as his mistress. The two lived together for a period of time, about half a year, and Li Guofeng spent a lot of money on Zhao Lingyu.

"But later, Li Guofeng's chain supermarkets ran into problems. About a year ago, Li Guofeng could no longer afford Zhao Lingyu's high consumption, and the two stopped contacting each other after that."

Chen Kai and his team spent a lot of time investigating Li Guofeng's situation. Although the investigation was short, they found many clues about Li Guofeng's business dealings, which were also related to Zhao Lingyu.

After Zhao Liying and Li Guofeng started living together, she didn't stay at home all the time. Instead, she continued to work at the KTV. Because of Zhao Liying, Li Guofeng met a supplier at the KTV.

"The financial problems that Li Guofeng's supermarket later encountered were related to this supplier. Our current investigation results show that this supplier defrauded Li Guofeng of a large amount of money and then ran away with the money. At that time, Li Guofeng and Zhao Lingyu had a big fight because of this, and he even beat Zhao Lingyu. Afterwards, since Li Guofeng didn't have much money left, the two parted ways on bad terms. After that, Zhao Lingyu worked in a KTV for a short time before quitting."

"Regarding Li Guofeng's situation, we are still investigating. Li Guofeng has not yet provided a conclusive alibi for the day of the incident, so this is our main breakthrough point."

Li Guofeng is now a key target of the Criminal Investigation Detachment.

While listening to Chen Jianguo's report on Qin Chuan, he kept writing and drawing with his hands.

"not him."

Qin Chuan suddenly said.

Ok?

Chen Jianguo was stunned for a moment.

"Director Qin, are you saying the murderer isn't Li Guofeng?"

Qin Chuan shook his head.

"No."

"But……"

Although Chen Jianguo and his team's investigation hasn't made much progress, they've finally discovered that someone close to Zhao Lingyu might have a motive for the crime. However, the investigation is still ongoing, and many things are still being verified. They've only given Qin Chuan a brief report, and the other party claims that he's not the murderer.

"Director Qin..."

Qin Chuan waved his hand.

He was well aware that Chen Jianguo and his team had only discovered one clue, and their report was simply to inform him that they were preparing to conduct an in-depth investigation into Li Guofeng. However, before the investigation even began, he had already dismissed that clue.

"Because the existing evidence does not support the claim that Li Guofeng is the suspect, look at these sets of footprints you have collected from the scene."

Qin Chuan pushed the draft paper on the table and several photos of footprints from the file in front of Chen Jianguo.
