While the manhunt is in progress

Chapter 182 Two cases in parallel
Seeing Du Yifei's figure leaving in a hurry, Song He felt relieved but at the same time, he couldn't help but feel a little absent-minded.

Wu Xuerui saw that his expression was wrong, and asked gently, "What's wrong?"

"It's a bad feeling not being able to intervene." Song He came back to his senses, looked at Wu Xuerui and said, "Team Du is the captain of the criminal police specially selected by the Yellow Bureau. He has grown up enough to sit in Yuan County."

"But now, both Captain Du and his carefully selected men are a little powerless to face such a difficult and major case."

"It's just that we are still providing support from other places. Being able to participate in a few cases through training is already the limit of the efforts of the Yellow Bureau and the Du team."

"It's not justified to intervene in other cases. Otherwise, Team Du wouldn't have to cover up like this. Let us analyze the case in his office."

Seeing Song He's regretful expression, Wu Xuerui suddenly smiled and said, "Just be content with it. Cross-regional law enforcement itself has many restrictions. It's thanks to Professor Shen that you can often come out to handle cases."

After Wu Xuerui finished speaking, she suddenly noticed that Song He's eyes rolled, and a thought suddenly rose in her heart. Before she could ask, she heard Zhou Kai's cold snort:
"Xiaoxue, are you still comforting him? Now he is thinking about how to entice Professor Shen to give him convenience!"

"Brother Kai, you can't say that!" Song He complained, and argued: "Look at our team, the work content is not worthy of our work ability. Every time we come out, we don't need half of our effort to solve the case. It's a serious waste of labour."

"Besides, I don't believe that Mr. Shen will not take these things into consideration when forming a support team, so there must be follow-up arrangements."

"And what I'm thinking about now is how to bring out these follow-up arrangements in advance."

Zhou Kai was speechless when he heard the words. He glanced at Wu Xuerui, who was skeptical, and Ma Xuexian, who believed in everything. He tried his best to suppress his [-]% belief, and sighed: "Your mouth is so unreasonable that you can force it out."

Song He chuckled: "I'll just take it as you are praising me."

The four of them chatted for a while, solved the remaining cases, and then patiently waited for the results of Du Yifei's investigation.

In the evening, when Song He got the information provided by Du Yifei on the people who left Si Village in the past four years, Ding Kui's investigation also made a big breakthrough.

"Ding Kui's alibi was provided by his lover and neighbors, saying that the two quarreled at night because of his drinking and smashed things."

"And this alibi was once the key to clearing his suspicion, but it was not mentioned by him at the beginning. It was discovered by our subsequent investigation."

"As for why the couple didn't talk about it in the first place, their explanations are more consistent, they just feel ashamed."

"However, through discussions and interviews today, we discovered that he bought a high-power video recorder about three weeks before the incident."

"So we think..." At this point, Du Yifei glanced at Song He with some gratitude and continued: "He and his wife recorded the quarrel in advance to create an alibi at the time of the crime."

"That's right." Song He read the Si Village personnel information provided by Du Yifei, and listened to his investigation of Ding Kui, and asked at the same time, "Is there any other evidence?"

"Yes." Du Yifei slightly puffed up his chest and said, "Today I asked a few police officers to secretly visit his neighbors back then. It is said that although the two of them usually quarreled, they basically didn't quarrel for long, only ten minutes. "

"But that time the two quarreled very loudly and lasted for more than an hour. And after that, Ding Kui and his wife never quarreled again."

"The supporting evidence is also good." Song He quickly flipped through the personnel information, picked up a pen to tick off a few names and said, "These people are more suspicious."

Du Yifei lamented Song He's high efficiency and took the information form. After looking down at the selected personnel, he raised his head in surprise and asked, "Consultant Song, the second uncle of the deceased is also a suspect?"

Song He nodded and said: "I know from your expression that you do not suspect him, but when identifying a suspect, you should never be fooled by appearances and personal tendencies."

"From a rational point of view, the second uncle of the child victim is the most suspected person."

"First of all, he is familiar with the child, so he has the ability to take the child away quietly."

"Secondly, he has worked abroad for many years and has been exposed to various industries. There is a high probability that he knows the value of the antique bracelet."

"Finally, it is his occupation and identity convenience. After working for many years to start his own business, he may encounter financial problems. Working in other places can logically leave afterwards without arousing suspicion."

Du Yifei was stunned and said: "Then the suspect is confirmed?"

"It's still early." Song He shook his head: "Being a suspect and being the murderer are two different things. They must not be confused. That's why we need to find the suspects and investigate them one by one."

Du Yifei nodded, suddenly remembered something, looked at Song He with some embarrassment and asked, "We have encountered some problems with Ding Kui's case, can Consultant Song help us?"

"No." Song He opened his mouth and Du Yifei was stunned. Then he looked at the dumbfounded Du Yifei and quickly said: "Captain Du, you are the leader of the criminal police team, so for the rest of the matter, I will only help you."

Du Yifei was overjoyed immediately: "Okay, thank you Consultant Song!"

Song He smiled and nodded: "Come on, what's the problem?"

Du Yifei quickly said: "The things we have investigated so far can only prove that the suspicion of Ding Kui and his wife is increasing, but there is no key evidence. Where should we start the next investigation?"

"Is there no evidence?" Song He rolled his eyes and thought, "It's been so long, it's enough time for them to destroy the relevant evidence. So instead of looking for evidence outside, it's better to let them expose themselves."

When Du Yifei heard that there was a way, he hit the snake with a stick and said, "Consultant Song, how do you do it?"

Song He smiled mysteriously: "Captain Du, have you heard of 'Prisoner's Dilemma'?"

"I've heard of it. I learned it when I was in the police academy." Du Yifei's heart skipped a beat, and he was suddenly a little excited.

"It's good to understand." Song He nodded and said: "In fact, we can slightly adjust the 'Prisoner's Dilemma' to operate according to their actual situation."

"We only need to magnify the distrust between Ding Kui and his wife while isolating their communication, so that they can be exposed. Specifically, we can implement it like this..."

In the evening, Ding Kui and his wife had just returned home from the travel agency, and before they had time to rest, they heard a rapid and forceful knock on the door.

The two had already exchanged glances, and Ding Kui asked through the door, "Who is it?"

"We are Yuan County Criminal Police Team." A man's voice came from outside the door: "Please open the door, there is a case that requires your husband and wife to assist in the investigation."

Ding Kui's heart moved, he winked at his wife, put it on the cat's eye to see the people outside, and then opened the door.

Three police officers entered the room one by one. After the first one showed his ID, he saluted with a gentle expression and said, "Now there is a criminal case that requires your assistance in the investigation. Please go to the police station to cooperate."
