Jiang Bai took Xu Mengyao into the interrogation room.

Lu Wen frowned and asked, "Advisor Jiang, is there anything new to discover?" ”

Jiang Bai pulled out a chair and sat down, his expression was cold, and he motioned to Xu Mengyao beside him to speak.

Xu Mengyao shuddered, lowered her head and said:

Pingping ...... It was Chen Xiao who killed him. ”

Lu Wen nodded: "Chen Xiao has already admitted it, but what ...... Advisor Jiang said?" ”

Jiang Bai folded his hands on the table, and said without hurry:

"Here's the problem, according to eyewitness testimony, Li Pingping's fall time was ten o'clock in the morning, and Xu Mengyao witnessed the accident caused by Chen Xiao's mistake at nine fifty in the morning, and there was a difference of ten minutes in the middle, that is, after Chen Xiao accidentally pushed Li Pingping off the roof, Li Pingping did not fall immediately!"

Lu Wen was puzzled: "I know this, since Li Pingping wants to write down the blood word, she must have persisted for a while, and after ten minutes, she fell off the stairs, what is the problem?" ”

Jiang Bai licked the socket of his back teeth and chuckled: "Is there monitoring?" ”

The accompanying technician immediately stepped forward, turned on the computer and faced everyone:

"Lu team, Advisor Jiang, the monitoring at the entrance of the rooftop is broken, and we only found the monitoring at the entrance of the teaching building."

Jiang Bai bowed his head, took the mouse, and adjusted the time to 9:50.

Monitoring starts playing.

At nine fifty-one, Chen Xiao's figure hurriedly passed by.

At nine fifty-three, Xu Mengyao came out closely.

At 9:59, the bell rang for the end of class, and there was a commotion in the teaching building.

At ten o'clock, Li Pingping had an accident.

At 10:05, a middle-aged woman with a black hat came out of the school building.

Jiang Bai paused, looked around at everyone present, and continued to speak:

"You see, this middle-aged woman hurriedly came out of the teaching building five minutes after Li Pingping's accident, wearing a light blue floral shirt."

Xu Mengyao bit her lip and whispered:

"I, I was hiding in the tool room at the back of the stairs and saw this woman hiding behind the rooftop door."

The house was in an uproar.

Lu Wen's expression was serious:

"Did you really see that? Was she hiding behind the door instead of passing by? ”

Xu Mengyao nodded, with firmness in her eyes:

"I'm definitely not mistaken, our school uniform is black and yellow, her clothes are too eye-catching, and our sweeping aunt also wears a work uniform, she is definitely not from the school!"

Lu Wen immediately ordered:

"Quickly check the other monitoring, Xiao Zhou, see if you can find the follow-up situation of the blue-clothed flower girl, Xiao Chen, you go and investigate if the students know this person."

The people under Lu Wen are very efficient, and it didn't take long for Xiao Zhou, who was in charge of technology, to find out the monitoring:

"Lu team, this is the surveillance on the second floor of the school library, just in time to be able to take pictures of the situation of the stairs of the teaching building, I processed her face with software, this is already the clearest picture."

Everyone looked at the computer, and it was a very ordinary and even slightly mean face.

At this moment, Qin Fa, who had been silent, suddenly had bloodshot eyes, stood up in a gaffe, and said in a dumb voice:

"I know her! She is Pingping's adoptive mother! ”

Shen Xiao's expression changed, and he glanced at Lu Wen, realizing that things were not simple.

Lu Wen immediately said: "Xiao Yu took Chen Xiao and Xu Mengyao back to the police station first, Xiao Chen left the aftermath, and the rest of the people went to Li Pingping's house with me." ”

Shen Xiao glanced at the director's fatal call on his mobile phone, sighed and said:

"Wen Gou, I won't go, I'll go back to filming obediently, it shouldn't be a problem to have Consultant Jiang."

Jiang Bai glanced at him and didn't speak.

Lu Wen nodded, patted his friend on the shoulder, and turned around and walked out of the temporary interrogation room.
