Song Tingchuan and Su Nan went to the police station in Yun City together.

Most of the people in the police station knew Su Nan, and Lin Chengfeng seemed to have explained in advance, and the people in the bureau did not stop them because they were high school students.

Su Nan took Song Tingchuan and found Lin Chengfeng's office with great skill.

Su Nan knocked on the door, and only after the first knock, Lin Chengfeng's deep but slightly tired voice came from inside

"Enter."

The two pushed the door in, and Lin Chengfeng was a little surprised to see that Su Nan was still following a person behind him, but he didn't say anything after all, just stood up and said to the two

"Don't ask anything yet, you come with me."

Su Nan subconsciously glanced at Song Tingchuan, and Song Tingchuan motioned for her to be calm.

The two followed behind Lin Chengfeng in silence.

They originally thought that Lin Chengfeng was taking them to a convenient place to talk, but they didn't expect that their destination was

Visitation cell.

And behind the metal fence, sat Principal Lan, who looked tired and wore prison clothes

Su Nan's pupils constricted at that moment, and at the same time, Principal Lan raised his head.

Seeing Su Nan and Song Tingchuan, he was even smiling at them, "You guys are here"

Su Nan's eyes turned red all of a sudden, "Senior brother, how can this be, why are you here, Senior Brother Lin, what the hell is going on?"

Lin Chengfeng sighed, sat down on the side, and did not speak.

Instead, Principal Lan said loudly, "Man, don't get excited, senior brother is fine." ”

Su Nan turned around and roared, "You're all in there, you tell me you're okay"

Principal Lan was stunned by Su Nan's sudden roar, and then laughed, laughing and laughing, his eyes suddenly turned red.

Lin Chengfeng took a deep breath and said to Su Nan, "Man, you sit first." ”

Song Tingchuan held Su Nan's hand and pulled her to sit down while calming her emotions.

Su Nan took a deep breath hard for a long time before he asked in a hoarse voice, "Senior Brother Lin, what the hell is going on?"

Lin Chengfeng glanced at Lan Feng, and then turned his head to Su Nan

"Do you still remember the murder case in Yunshi some time ago, the deceased Yang Yu?"

Yang Yu, Yang Yu

It's this name again, Su Nan felt familiar before, but when Lin Chengfeng mentioned it, Su Nan frowned, "This name, I seem to have heard it somewhere." ”

Lin Chengfeng tugged at the corners of his mouth, "Of course you have an impression." ”

"Hmm"

Lin Chengfeng's chin tapped in the direction of Principal Lan, "Yang Yu, it's your Senior Brother Lan's son-in-law." ”

When Lin Chengfeng said this, Su Nan and Song Tingchuan stood up at the same time in shock.

Yang Yu is the son-in-law of Principal Lan, Yang Yu is dead, and Principal Lan is almost ready to answer in it.

As if confirming their guess, the next second, Lin Chengfeng said

"Yang Yu was violent against Lan Xi, and was bumped into by Lan Feng, and Lan Feng was angry and beat him to death."

Lan Xi, the daughter of Principal Lan.

Seeing his daughter being subjected to domestic violence, Lan Feng, as a father, inevitably lost control, and this loss of control caused a catastrophe.

killed someone, Lan Feng's first reaction was to flee, Lan Xi also desperately covered him, Lan Xi studied computers, she tampered with the surveillance after Principal Lan left, and after making sure that she couldn't find the slightest evidence of his father's murder, she reported the case, saying that her husband died tragically at home for no reason.

The police did not find any flaws at first, and thought that there was a murderer in the city with extremely clever modus operandi, and urged the public to be careful when going out.
