How could Gao Bin know how to investigate a case? It would be fine if he had high-tech assistance. In this day and age, handling cases depends entirely on luck.

Of course, if he were a veteran criminal investigator, his experience would also play a vital role, but unfortunately he is not. He can only rely on his three generations of experience to advance, and he has to bite the bullet.

He knows very well that this case is crucial to whether he can open up a situation in this world.

Moreover, Gao Bin had a vague suspicion that maybe this case would not need to be investigated to get to the bottom of the matter?

Just when he thought of this, he said to Er Mazi:

"Don't rush, think slowly and don't miss any details."

Er Mazi didn't act stupid at this time. He recalled carefully for a moment and nodded:

"The night before yesterday, Xiao Qiu suddenly came to see me at home and said he wanted to play cards."

Gao Bin guided:

"There was no agreement before, right?"

"No, and Xiaoqiu doesn't have much money. No matter how much he loves playing cards, he doesn't dare to play too often."

"In other words, you just had a card game before this?"

"Yes, the night before yesterday, in Kangjiazhuang, there was a card game organized by a man named Kang Laoliu."

Another character was involved. Gao Bin wrote down the name and continued to ask:

"Then what? You went to play cards?"

"I went. I was on vacation that day and was bored at night, so I went."

"Go on, what's wrong with Xiaoqiu?"

Er Mazi chewed Yahuazi:

"To be unusual, Xiaoqiu was very generous that night and paid very happily."

A person with no money suddenly becomes so generous, even a fool knows something is wrong.

Er Mazi suddenly realized the problem:

"No way? Is it Xiaoqiu?"

Gao Bin shook his head:

"If there is no evidence, don't say anything for now. Think about it again. Did Xiaoqiu reveal any information that day, or had close contact with anyone?"

Er Mazi frowned and thought:

"It's nothing, I'm just very excited the whole night, no matter whether I win or lose money, you know that when he lit the cannon, his mouth was not clean before, and he would greet other people's mothers with curse words."

Hey? This wording is quite civilized. Gao Bin smiled in his heart and nodded in affirmation:

"Okay, you can go back and reminisce, and if you remember anything, tell me as soon as possible."

Er Mazi said worriedly:

"Is it really Xiao Qiu? I don't think he has the courage. Everyone in the Second Ward knows that Xiao Qiu is notoriously timid."

Gao Bin said meaningfully:

"He may not have done it himself, maybe it was an intermediary?"

Er Mazi's eyes suddenly widened:

"Is it Lao Chen? But..."

At this time, Guan Dahai came in with a middle-aged couple, and Gao Bin promptly told Er Mazi to shut up:

"You go and take a rest first. I'll call you later."

I sent you a message to welcome Guan Dahai:

"Are they responsible for delivering meals to the Second Ward?"

"Yes, Lao Kang and Sister-in-law Kang are both villagers of Kangjiazhuang."

At first glance, these two people looked like people who were making a living in the fields. Somehow they got a chance to find a job delivering food in the prison, but they still couldn't change their rustic, simple and honest nature.

But being brought in for questioning now, they must be extremely nervous, as you can tell by looking at their hands that keep rubbing the corners of their clothes.

Gao Bin put on a smile:

"Brother Kang, sister-in-law, don't be nervous, just ask a few questions and you guys will answer them truthfully."

Brother Kang's face is full of wrinkles, and his dark skin is covered with weather and rough texture. It makes him older out of thin air. He looks like he is in his fifties or sixties, but in fact he is only in his forties.

"Hey, sir, just ask." Brother Kang responded and swallowed, not daring to look directly into Gao Bin's searching eyes.

"What time did you come to deliver the meal this morning? What time was it when you called the number behind me? Did you see anything unusual?"

A series of questions made these two country people confused, and the courage they had finally accumulated disappeared without a trace.

However, Guan Dahai was familiar with them and comforted them softly:

"It's okay. I just ask you to cooperate with the investigation and answer truthfully."

Brother Kang calmed down, looked at each other and said:

"We entered the second prison area at 6:10, and food was served from this floor. It shouldn't take more than 10 minutes to get to this cell."

Gao Bin nodded:

"That is to say, you arrived at the number behind me around 6:20."

The eldest brother and sister-in-law nodded repeatedly.

"Can you tell me about your cooking process?"

"We each have a bucket. My mother-in-law is responsible for making pancakes, and I am responsible for serving vegetable soup. After beating, we push it in through the small door below."

Gao Bin raised his eyebrows:

"Don't see any blood?"

"Blood?" Brother Kang shook his head crazily: "We didn't see anything."

Having said that, Gao Bin saw something strange on Mrs. Kang's face.

So he took a step forward and whispered:

"Sister-in-law, did you see something? It doesn't matter, just tell me. I guarantee it won't have any impact on you."

Sister-in-law Kang hesitated, looked at her man, then at Guan Dahai, and finally her eyes rested on Gao Bin.

She puffed up and said:

"I'm not sure. It was still dark at the time. I vaguely saw a puddle of water on the ground, but I didn't think much about it."

Water?

It should be blood, but it hasn't flowed out yet. In the dim light, it wouldn't be strange to see blood as water.

Gao Bin assumed the perspective of Mrs. Kang and made up the scene. In this way, Director Fei's death time was within a certain range.

"Okay, Brother Hai, let's send them back."

Guan Dahai nodded and asked someone to send the couple out.

He followed Gao Bin and asked:

"What's the progress?"

"It is basically certain that Director Fei died between 5 and 6 o'clock."

Guan Dahai is not a fool. Thinking of Sister-in-law Kang's answer just now, he agrees with Gao Bin's judgment:

"That's right. In that case, as long as we find the team members patrolling on the negative floor between 5 o'clock and 6 o'clock, we can further narrow the scope?"

Gao Bin is not so optimistic. The other party has made such a thorough plan and will definitely attack in the blind spot of the patrol. It is impossible to attack during the patrol.

"Let's check if anyone changed shifts last night? He wasn't supposed to be on duty, but suddenly he was on duty. Do you understand what I mean?" Gao Bin's eyes were bright and had a convincing intimidation.

"Um, I understand what you mean. I'll go check the duty records so that it's clear at a glance."

"Well, I'll go find Section Chief Lu and report the current progress to him."

Gao Bin believes that Director Fei's death is not that simple and may involve a higher-level struggle. He, a small soldier, should try not to get involved too deeply to avoid being implicated.

Therefore, he must be cautious and report every step he takes. Once Lu Youming shows an attitude that it's okay, he will stop immediately!

I came to Lu Youming's office, explained my thoughts and analysis in detail, and quietly waited for the other party's instructions.

But Lu Youming was not in a hurry to give advice. He puffed away with boredom in his mouth and could not see any waves on his face.

It wasn't until he finished smoking a cigarette that he quietly spoke:

"Let's continue the investigation. The most suspect at present is Lao Chen?"

"There is no evidence, but in terms of direction, Lao Chen is the most suspicious."

Gao Bin's words are so watertight that no one can find any fault.
