C479

After Rong Yin's case came to an end, Fu Nuan's attention returned to the case.

If there is any doubt, but there is no evidence pointing to it, is it the wrong direction of the investigation, or a certain link has gone wrong, so that she ignored something?

Before she knew it, she fell into a deep thought again. She said: "curse the post, hurt Lin Ke by the flowerpot, fall from the building inexplicably, the homestead man who thinks Cheng Xin cheated money, Cheng Xin's ex boyfriend, ex boyfriend's brother..."

There must be some connection between these people and events, but what is it?

And Cheng Xin have hatred, hate enough to kill her, in the current known figures, the boy who thinks Cheng Xin cheated him of money, as well as Sun Xiang's brother, are suspected.

However, there is no evidence at present, and Chen Dong admits without hesitation that he really hates Cheng Xin. If he is really a murderer, his psychological quality will be better and he knows how to bluff.

Sun Fei, on the other hand, said almost everything. Even Fu Nuan felt that if he suspected that he was a good brother who had lost his brother, he could not bear it.

"What's wrong..."

Rong and gently flicked her head to call back her wandering mind.

"Professor Rong, my brain is running out of capacity. Help me think about it. What's wrong with it? "

"Well."

He let out a nasal sound, but did not continue to speak.

Fu Nuan looked at him strangely and found that he was staring at her with meaningful eyes.

Generally speaking, such Professor Rong

"Husband, you are so smart, can you help me? Give me a hint... "

Rong and Meifeng pick slightly, hook finger to indicate her past.

She came up to him and sat in his arms.

His fingers rolled her hair gently and said slowly, "what do you care about most now?"

Fu Nuan thought for a moment and replied, "rooftop. How on earth did the murderer avoid the sight of the security guard on duty and take people to the roof and then throw them down? "

"It doesn't sound possible, does it?"

Fu Nuan nodded, which was what she couldn't think of most.

"If the security guard is telling the truth, it is impossible. But if he lies... "

"You mean..."

Fu Nuan was suddenly enlightened by such a sentence.

Maybe the image of the security master is too honest and honest. She never thought that he might not be telling the truth.

Of course, it does not mean that he conspired with the murderer or covered up the murderer, but if he lied, he was not always there during his duty, and he was afraid to take responsibility for his death, so he chose to hide it. This possibility is not without.

"Why didn't I think of such a simple reason?"

Fu Nuan rubbed her head with some annoyance. She was said to have been pregnant for three years. She almost doubled. How could she feel that her IQ was not enough?

"Simple?"

He raised his eyebrows and asked in a deep voice.

"No I said the wrong thing! It's not easy at all. My husband is the best

Fu Nuan tried his best to remedy it before Professor Rong was angry.

"Well, worship me."

With such doubts, Fu Nuan decided to talk to the security master the next day to see if he could ask for something.

……

The next day.

Fu Nuan arrives at the teaching building where Cheng Xin fell off early. The security master who was supposed to be on duty at the entrance to the rooftop is not there.

He should have been on duty at this point.

Fu Nuan remembered that the time when Cheng Xin fell from the building that day was about this time.

At this time of the day, the security guard is not on his post. Is it a coincidence, or is it his habit, every day.

And someone happened to grasp this point, while he was away, will Cheng Xin dizzy after dragging the roof?

If it's the same as she guessed, the man must have been premeditated. Maybe he knows the security guard, or he has been observing his actions for more than a few weeks.

Fu Nuan sat in the security guard's position, waiting for people to come back. This wait was almost half an hour.

……

"Sir, are you back?"

Fu Nuan saw the figure not far away. It was the security guard who took her and Rong on the roof that day.

Seeing Fu Nuan, an unnatural expression appeared on his face.

"You Why are you here again? Didn't you see it last time? "

Fu Nuan said with a smile, "I'm not coming to see the rooftop. I'm looking for you."

On hearing this, the security man's face changed greatly. Was his secret discovered?

"Looking for me? What do you want from me? I went to the bathroom just now, and I had a stomachache

"I was here almost half an hour ago. Diarrhea, more than half an hour? How are your legs? "

Fu Nuan stares at the security guard's leg suspiciously. He is so guilty that he can hardly help saying everything."You work early and go to bed late. You are also very hard. I can understand your laziness. But your superior should not be as reasonable as I am. Just tell me if you will leave your duty position for more than half an hour at this time every day, and I swear I won't tell your leaders

The security guard looked at her in embarrassment, wondering if she should believe what she said.

"If you leave the post without permission for one time and leave without permission for many times, your handling result will not be too different, so if it is, it doesn't matter if you admit it. On the contrary, what you said may be of great help to the detection of Cheng Xin's case. "

"I..."

The security man hesitated and finally admitted.

"It was more than ten minutes before the girl fell from the building. I ran to be lazy as usual, but how could I know that such a thing would happen? I am afraid of being found to be responsible. I can only hide it and return to my post when I am in chaos I didn't mean to Alas

Finally, the truth was told, and the security master was relieved.

Fu Nuan frowned solemnly after listening.

That said, the previous speculation is more likely.

"Does anyone know about your habit?"

The security man thought about it, moved his mouth, but he kept silent and swallowed his words back.

"If you think of anything, please let me know. Otherwise, you may be counted as a cover up

Fu Nuan continues to try to persuade and pry out the secret in his mouth.

"Well There is a young man who knows that I go back to hide my laziness at this time of day. About a month ago, when I returned to my post and saw him sitting in my seat, I was shocked. He said that he likes to be quiet, go up to the roof to breathe, reading on it will be more involved. I was afraid that he would report me, so I agreed. Later, I found out that the young man was very good. He would cover for me and sometimes bring me some food... "

Speaking of this, he stopped abruptly and asked Fu Nuan in surprise: "you are not doubting him, are you? No It's impossible. The young man is very gentle and looks sunny. He can't kill people. "

Fu Nuan pursed his lips. He didn't look like the murderer. He might not be the murderer. After all, the murderer would not write those big characters on his face.

"What's his name?"

The security man shook his head and said, "I don't know..."

Under Fu Nuan's questioning eyes, he still insisted.

"I really don't know. I didn't ask his name..."

"Uncle, I'll give you..."

The voice stopped abruptly.

Fu Nuan hears the sound and turns her head to see the man. She has just met
