After Zhang Nan and Wu Meili walked out, Li An preached to Gao Feng and Xiao Yue: "In fact, there is a fifth voice. Pen, fun, pavilion www. biquge。 info”

"The fifth voice?" Xiao Yue frowned suspiciously.

Gao Feng also frowned slightly, and looked at Xiao Yue with a puzzled expression.

Everyone has listened to the audio twice just now, and there are only four voices, where did the fifth sound come from.

Ang Lee held the mouse in his hand and clicked on another audio and said, "Listen to this again, this is the sound I made when I maxed out the audio." As he spoke, he stretched out his hand and turned the speaker up to the maximum.

"Huh?"

"Glory, be careful!"

"Knock, knock!"

The first is the sound made by Wu Rongrong, the second is the sound made by Xia He, and the third is a mysterious and rapid sound, and the next should be a "bang" impact.

But just before the sound of the car crashing through the guardrail of the mountain road sounded, there was a soft "click", which was smaller than the sound made by Wu Rongrong, so it was not heard before.

"What's that sound?" Xiao Yue asked with a frown.

Li An shook his head and replied: "I can't figure it out yet, but this soft sound appeared before the car crashed into the guardrail, I think it was very crucial, or it was this sound that finally led to Wu Rongrong's death." ”

Gao Feng's face was heavy.

The sound of "click" almost overlapped with the sound of "bang", but it was a little bit ahead.

In that case, there are many types of noise that can occur, such as a loose part of the car, or a sound from an ornament in the car, and it is very difficult to figure out what the sound is coming from.

"Anything else you found?" Gao Feng asked.

"Oh, yes. The two cigarette butts you asked me to examine have results, and according to the DNA comparison, they were smoked by the same person. Ang Lee replied.

Gao Feng's eyes lit up, nodded vigorously, got up and said, "If you find anything, contact me, goodbye." With that, he turned and walked out.

Xiao Yue hurriedly followed out, and asked puzzledly, "What's the matter with the cigarette butts you asked Li Ancha?" ”

"It's just some kind of speculation, and there's no way to confirm it yet." Gao Feng replied, glanced at the time as he spoke, and then said, "Zhang Nan estimates that it will take a while to come back, let's find a place to sit first." ”

"yes, okay." Xiao Yue answered softly and walked towards the gate of the police station with Gao Feng.

Just when the two of them walked to the gate, they suddenly found a person standing under the tree outside the door and wandering, and stopped after seeing the two.

Hu Zheng!

"You're here for me?" Gao Feng said and greeted him.

Hu Zheng nodded and replied, "You said that if I think of something, I can come to you." ”

"What do you think of?" Gao Feng asked.

Hu Zheng replied: "I remember that it was the night before Xuelian accidentally fell from the building, and she suddenly called me and said that she always felt that someone was following her for a few days before. ”

"Someone stalking her?" Gao Feng's eyes lit up again, and he asked, "Are you sure?" ”

Hu Zheng replied cautiously: "I don't know if anyone is following her, but at that time, not long after her father's accident, she had just divorced me, and her mental state was not very good, and she was always suspicious." So, I didn't pay much attention to it at the time, but I only remembered it when you asked me about it today, maybe it had something to do with her death. After speaking, he said nervously, "Maybe I'm thinking too much." ”

"No, you're doing a very good job, you can tell me whatever you think or suspect." Gao Feng boasted.

Hu Zheng nodded and said, "I still have classes in the afternoon, so I'll go first." ”

Seeing Hu Zheng leave, Xiao Yue said with some puzzlement: "Even if someone really followed Wang Xuelian before she died, how could it help us?" Don't forget, Xia He was downstairs when Wang Xuelian fell to her death from upstairs, and she had no conditions to commit the crime at all. ”

"But what if she has accomplices?" Gao Feng asked.

"Companion?" Xiao Yue's brows tightened, and she looked at Gao Feng with a puzzled expression.

Gao Feng smiled: "If Xia He has accomplices, then all problems will be solved." ”

Xiao Yue frowned again.

"Get a call for Zhang Nan and tell him that we are waiting for him here." Gao Feng commanded, and after a slight pause, he spoke in a low voice, "It's time to prove my inference." ”

Half an hour later, Zhang Nan drove back to the police station in a police car, and as soon as he saw Gao Feng and Xiao Yue, he said: "The car accident last night was really an accident, which made Miss Wu very disappointed, and I was a little worried that she would not be able to think about it." ”

"Not necessarily." Gao Feng said in a low voice.

"What do you mean?" Zhang Nan frowned puzzled.

"Let's talk about it later, let's take us to the scene of the incident first." Gao Feng commanded.

Zhang Nan saw that Gao Feng didn't say anything, so he could only look at Xiao Yue, who knew that Xiao Yue also put on an unknown appearance, so he could only drive to the scene of last night's car accident.

When the three of them arrived at the scene of the accident again, the car that had been burned to the bottom of the ditch was still at the bottom of the ditch, and it was not easy to get it up.

In addition to the cordon, even the traffic police on duty were gone.

"What are we doing back here?" Xiao Yue asked puzzled.

"Decide on one thing." Peak Return.

"What's the matter?" Xiao Yue asked.

Gao Feng did not answer immediately, but asked rhetorically: "Under what circumstances will the car rush down without any brake traces?" ”

"The driver was drunk and didn't have time to react, or was asleep." Zhang Nan gave the old driver's answer.

Gao Feng shook his head and said, "But Wu Rongrong didn't drink, and from the recovered audio, it can be heard that he didn't fall asleep before the incident." ”

Zhang Nan frowned, indicating that he didn't know.

"Ahh Could it be that there is a problem with the brakes? Xiao Yue suddenly exclaimed.

Zhang Nan snorted lightly and said, "How is that possible?" ”

Gao Feng nodded, looked at the mountain, and said with a deep face: "It's not far from the farmhouse on the mountain, and there are no cars running on the mountain late at night, and there is basically no need to brake here from there." ”

Zhang Nan nodded, he completely agreed with this.

"Remember Wu Rongrong's soft voice? He must have noticed a problem with the brakes. Gao Feng preached, and after a slight pause, he continued, "There was a rapid 'dong dong' sound later." If I guessed correctly, it must be the sound of Wu Rongrong desperately stepping on the brakes. ”

"But there are no brakes at the scene?" Zhang Nan said with a frown.

"This means that there is a problem with his brakes, so that he has no way to brake, and just drives the car down!" Gao Feng said in a deep voice.

"Your reasoning is possible, but one thing says otherwise!" Zhang Nan posed as a "police detective" and said.
