Ye Fan was pinned down by Lu Yuan in the corner of the alley, covering his mouth and nose, unable to move. [] At the same time, the sound of soft footsteps came from the corner of the alley.

"Ta-ta...ta-ta."

The sound gradually became clearer from far to near, and was heading towards where they were.

Seeing Lu Yuan's nervous expression, Ye Fan also realized something was wrong.

Judging from the conversation just now, Lu Yuan should have come to the murder scene alone. At midnight, we are at the murder scene again. Who could be the guy on the corner at this moment?

Lu Yuan made a silent gesture, and while letting go of Ye Fan, he pulled out the police rifle from his waist.

But the mysterious man at the corner also noticed something, and gradually slowed down his movements. Following the moonlight, the guy's continuously elongated shadow was clearly visible.

Who could be the mysterious person who suddenly appeared? The murderer? Or someone else related to the murder. Ye Fan took a deep breath and tried his best to recover from the negative impact of the immersion.

There is no doubt that the serial killer who committed numerous murders is an adult male, and his methods are cruel and extremely cold-blooded. If they were to meet him head-on in this situation, he and Lu Yuan alone would not necessarily be able to gain the upper hand.

However, once this opportunity is missed, it will be very difficult to catch the guy again.

While hesitating, Lu Yuan took the lead in taking action.

He first signaled Ye Fan to stay behind him, then he clenched his gun and ducked around the corner.

The opponent's identity was unknown, and Lu Yuan didn't want to rush forward, but thinking about the weak expert behind him, he could only grit his teeth and fight against it. No matter what, the gun in his hand was also his last trump card.

At this moment, the figure at the corner seemed to be aware of the danger, and there was no movement. The two groups of people were deadlocked in the dark alley, neither of them daring to take the lead in taking action.

Ye Fan looked at the shadow on the ground and suddenly realized something was wrong: "No, that guy is going to run away!"

When Lu Yuan heard this, he grabbed his gun and rushed out of the corner.

"Police, don't move!"

However, the figure turned around long ago and ran towards the other end of the alley.

"Oh shit!"

Lu Yuan cursed secretly and followed quickly. Just as Ye Fan was about to say something, seeing that Lu Yuan had already run far away, he could only grit his teeth and keep up.

There are many alleys connected near the crime scene, and the road conditions are complicated. Although the figure is not fast, he is very aware of the surrounding environment. Lu Yuan has been following closely, but he has never been able to close the distance between them.

Gradually, Ye Fan only felt that his breathing was intensifying, his heartbeat was speeding up, and his legs were as heavy as lead. The strong wind whistling past his face was like a sharp knife cutting his throat, and the ecstasy just now consumed most of his energy.

He couldn't muster any more energy to keep up with Lu Yuan's footsteps.

There were many side roads near the Third Alley, and I was just thinking about whether I should change directions and catch up, when at the end of the passage, a gunshot suddenly sounded.

"boom!"

The unexpected gunshots completely shattered the peace around them.

What happened ahead? Who fired the shot? Is it okay after a long journey?

The bad premonition became stronger and Ye Fan had no time to rest, so he gritted his teeth and rushed over.

More than ten meters away, Lu Yuan covered his face with one hand and leaned half against the wall.

Warm blood was dripping down half of his face, and his right hand was holding the gun tightly. Judging from the situation at the scene, it was speculated that the shot just now should have been fired by Lu Yuan.

Seeing that Lu Yuan was okay, Ye Fan was relieved. He knew that Lu Yuan was Kong Fangping's confidant, and if there was really something wrong with him, he would not be able to explain it to Kong Fangping.

"You were careless, that guy was already prepared." Lu Yuan wiped the blood from his forehead and put away his gun: "He rounded the corner and caught a cat behind the trash can. As soon as I ran over, I took a sap.

"

"So you fired a warning shot?"

Lu Yuan took out a cigarette from his pocket, bit it in his mouth, and smiled: "No, I wanted to hit him in the leg, but I didn't shoot for too long, so I missed the target."

Ye Fan glanced at the wound on Lu Yuan's forehead and asked in a low voice: "Have you seen what that guy looks like?"

Lu Yuan lowered his eyelids and tried to recall the scene not long ago: "Wearing a mask, about the same height as me, he should be a man. Hey, expert, do you think that guy is the murderer? If so, then I didn't miss the meritorious service just now.

Good opportunity?"

"He can't run away!"

"What do you mean, you have a way to catch that bastard?"

Ye Fan ignored Lu Yuan and lowered his body and walked forward along the alley entrance.

Since they didn't expect to meet the mysterious person here, then in turn, the mysterious person probably didn't expect Ye Fan and Lu Yuan to appear here. The chase just lasted for about fifteen minutes. This period of time was mysterious enough.

A person leaves traces that reveal his identity.

The road conditions near the Third Alley were in bad condition, and some of the rain-soaked ground had not yet completely dried up. Moving forward along the passage, Ye Fan quickly discovered a few brand new footprints on the muddy ground in several places.

Two different shoe prints were staggered on the ground in front of him. Lu Yuan was wearing Nike shoes that had just been launched, so the remaining prints could only have been left by a mysterious person.

Lu Yuan quickly understood Ye Fan's thoughts, hurriedly took out his mobile phone and dialed Murong Xue's number.

"It's me, Lu Yuan. I'll ask Old Hu from the Footprint Department to come to Third Alley. We can meet and discuss other matters in detail. In addition, this matter must be kept confidential. Before the results come out, I don't want other colleagues to know...

.”

Footprint inspection is also called footprint inspection. It is a specialized technology for discovering, extracting, analyzing and identifying the footprints related to the case. It mainly extracts on-site footprints and determines the gender, age, height, body shape and walking posture of the perpetrator based on the characteristics and distribution of the footprints.

Weight-bearing conditions and coming and going directions.

Due to heavy rains in the previous four murder cases, the police never recovered any traces of the suspected murderer's footprints at the scene. The complete footprints on the mud in front of them may become a key clue to lock in the murderer's information.

After hanging up the phone, the two fell into silence again.

Tonight's sudden discovery made it difficult for Lu Yuan to contain the joy in his heart. However, Ye Fan on the side looked very calm. Compared to the shoe prints in front of him, he was more concerned about the inexplicable sense of familiarity that suddenly emerged when he was fascinated.

The murderer was most likely to know Guo Xiaohui. This was something no one had thought of. If he continued to follow this clue, he might be able to gain unexpected results. However, he did not plan to tell Lu Yuan about this discovery for the time being.

"By the way." Lu Yuan puffed out the smoke and looked at Ye Fan in front of him: "It's late at night, if you don't have a good rest in the hotel, what are you doing here?"

"What are you here for?" Ye Fan didn't even raise his head, his tone was as cold as ever.

"Of course I came here to look for clues. I always feel that I overlooked something in the morning." Under the smoke, Lu Yuan's eyes were always locked on Ye Fan.
