The three of us spent a happy morning at home, and then Lu Lingyun and I walked out of the house full of energy to continue investigating the two cases of Antique Street and Chengnan River.

"Xiaoyan, I brought back some of his personal belongings from Du Baoyu's house last night, and we will check them at the city bureau in a while."

"Good. Last night's interrogation, he didn't reveal the slightest suspicious place? ”

"Although his alibi is valid, it is also possible to buy a murder, and when asked about the memories between him and Zhou Wei, he said a little vaguely, his explanation is that too much time has passed, and he doesn't remember much anymore."

"Brother Lu doesn't believe what he says?"

He frowned and thought for a while before answering me: "Whether it is intuition or experience, I feel that there is something wrong with Du Baoyu, he may not be the murderer who directly killed Gu Hongjun and Zhou Rentian, but he should know some inside information, so today I let Jin Zi and Zhou Chang continue to interrogate, and I must pry his mouth open." ”

"Or I still use the old way to deceive him, Zhou Rentian was pushed into the river with the car that night, although I didn't see the criminal's face clearly, but I can still tell some details, if he panics, maybe he will show his feet."

"Okay, then it's troublesome Xiaoyan."

We arrange today's work and do it step by step according to the plan.

It is up to me and Jin Zi to interrogate Du Baoyu, he looks much haggard than yesterday, after staying up for so long, ordinary people are already on the verge of a nervous breakdown, and it is estimated that he will honestly explain anything.

In addition to looking a little sluggish, Du Baoyu's willpower was quite tenacious, so he asked for a cup of coffee and bread, and continued to cooperate with the police's questioning.

"Du Baoyu, what purpose did you want to achieve by gluing Zhou Rentian's hands to the steering wheel with super glue that night? The thrill that he can't break free from and watch his slow death bring you? ”

Du Baoyu rubbed his eyes and looked at me, and said with an innocent face: "I don't know what you're talking about, I said that I was at home that night, and the surveillance video of the community can prove that I never left." ”

I smiled coldly and continued: "I saw it when Captain Lu was interrogating you yesterday, you are a very smart person, high IQ, and the surveillance of a small area, if you want to avoid it, I believe it is still very easy to do, and even the police are in your plan to find the door, right?" ”

"I'm a smart person, but can I equate myself with a criminal with a good academic record? I understand that you police can only detain me for 24 hours, and I believe that justice will do me justice. "Du Baoyu seemed to be very dissatisfied with my interrogation method and became a little resistant.

I don't care, Lu Lingyun thinks he has a problem, so I have to get to the bottom of things.

"Why are you so excited? I haven't given you the key evidence yet. As I spoke, I took down a photo from the folder in front of me, which was the picture of the rear body of Zhou Rentian's white car.

"The murderer left palm prints when the cart went down the river, as long as you compare it with your hand, it is clear whether it is black or white."

"Okay. Then you should hurry up and don't waste my time. Du Baoyu said and put his two hands on the table.

I thought to myself, is it really not him?

The door of the interrogation room was suddenly pushed open, and Lu Lingyun walked in quickly, holding a few envelopes in his hands.

"Du Baoyu, I didn't expect that in this era, you are still willing to contact others by sending letters."

He looked at the envelope in Lu Lingyun's hand and replied calmly: "The old dean is old and can't use a smartphone, so I will send a letter to express my miss for her when I have time." ”

"Obviously in a city, you don't even have time to drive and take a look?"

"I... I..." Du Baoyu didn't say anything for a long time.

"I advise you to confess as soon as possible, you know that the police will not let go of any suspicious clues, and we can investigate it if you don't say it." Lu Lingyun gave an ultimatum, and Du Baoyu finally opened his mouth.

"I had a girlfriend and didn't want her and her family to know that I was an orphan, so I didn't go back to the orphanage for many years."

This guy really found a good reason, Lu Lingyun was not discouraged, he patted me on the shoulder and asked me to go out with him.

"Xiaoyan, let's go to the orphanage."

"Okay, Brother Lu."

Lu Lingyun drove an off-road vehicle to take me all the way to the Fengtian Orphanage at the western end of the city, and I heard from him on the way that the orphanage had been relocated several times, initially founded by a private entrepreneur, and now has become a semi-public welfare social welfare institution.

The car drove to the front of the orphanage, and sure enough, the plaque was engraved: Fengtian Welfare Institute.

The spacious courtyard, the four-storey white building, the green grass and a few newly sprouted weeping willows, the warm environment makes people feel relaxed and happy.

"It's a nice place." I got out of the car and looked around, but I didn't see the teacher or the children, until I heard the sound of reading aloud from the small building.

After Lu Lingyun said hello to the uncle in charge of the door, we entered the welfare home smoothly.

I heard that the current dean is an excellent teacher hired, and the old dean is very old and lives alone in an old house in the back.

Lu Lingyun and I went around the four-story building and went directly to the old dean, where she lived and the welfare home were separated by a fence wall, and there was also a small independent courtyard, where an old cat sat on a rocking chair, and next to it squatted an old lady with gray hair.

The old man had his back to the fence gate and seemed to be digging into the ground with a small shovel in his hand.

Lu Lingyun stopped and knocked on the door, and the old man looked back at us.

"Who are you looking for?"

"Hello, is this the old dean?"

The old lady stood up with a smile and patted the dust on her body, and replied, "Don't call me any dean, just call me Teacher Liu." ”

"Hello Mr. Liu, we are from the Fengtian Public Security Bureau, my surname is Lu, and his surname is Yan."

Dean Liu's originally kind smile showed a hint of stiffness, but it quickly eased.

"Comrade policeman, please come in."

She greeted us warmly, but the big cat sitting in the rocking chair was not very happy, and hurried into the house when the stranger came in.

Lu Lingyun and I sat on a small pony, and Dean Liu brought us hot water from the house.

"Teacher Liu, you don't have to be busy, we came here today just to learn about Du Baoyu."

"You ask Baoyu~~ He is a good boy, he was smarter than ordinary children when he was a child, if it wasn't for an accident at home, maybe he would be more productive now."

The old dean has a very high opinion of Du Baoyu, and it seems that his character is not bad.

"Mr. Liu, do you have any information or photos of him when he was a child?"

"The materials are all in the archives of the school building, and there are a few photos, and I usually like to look at these children when they were children, and I always feel as if they are still around." Dean Liu's words made me feel sad, I grew up for more than ten years, and finally left only her old man and a cat as companions.

"Godmother, I bought you a sauerkraut tree, can we eat white meat stewed sauerkraut at night?!" Suddenly a man's voice came from outside the fence door.
