If you don't count the last time the car broke down in the middle of the night, this is the second time that Song Huai is willing to go to the scene of the crime.

It's still dusty, and the smell of old and concrete walls after the sun has scorched it.

Zhao Cheng felt that Wang Hao was not a murderer, but he couldn't say anything wrong, according to what he said, when the case encountered a bottleneck, he would go back to the place where he started, and maybe there would be any unexpected discoveries.

So Song Huaiyuan was pulled over by him again.

To be honest, she didn't really want to come to this place, and as soon as she stepped into this abandoned building, her heart began to beat faster, and she always felt a bad premonition.

Zhao Cheng walked in front, walking very slowly, looking at each floor carefully, and then turned his head to ask her if she saw anything, and after getting a negative answer, he continued to walk up, and when they reached the fourth floor, they saw messy footprints on the ground, and countless markers, and the cordon swayed gently with the breeze.

Most of the cement pile at the far end has been shoveled away by the Forensic Section, and there are occasional drops of blood dripping from some places, showing the world that there have been terrible cases here before.

"What's new?" Zhao Cheng stood at the top of the stairs and asked her as usual.

Song Huai shook his head, "No." ”

Zhao Cheng continued to walk up, his steps became more and more careful, looking a little funny, and after taking two steps, he turned back again, "You go ahead, tell me what you see." ”

Is he afraid of destroying the traces of the scene?

"Hmm." Song Huai was willing to do the same, and he also leaned over, looked at the ground carefully, and walked forward cautiously, "We didn't see it below, what can there be?" ”

Zhao Cheng stood against the wall, and he didn't know when he had hooked a cigarette in his hand, "I don't know, I think there should be something." ”

"Come on, there's nothing on the stairs."

In the last few nights, the wind has been blowing, even if there were traces at that time, left on a thin layer of dust, after the baptism of the wind in the past few days, if not blown away, it has long been covered with new dust.

The two of them walked four or five floors, still didn't find anything, and immediately arrived on the rooftop.

The building has a total of 12 floors, and there is an elevator hall in the middle of each floor, but now it is an empty shell, the elevator has not been installed at all, and the two people only climbed to the roof on foot.

Originally, after climbing the stairs for a long time, Song Huaiyuan was already sweating a little, but the cold wind on the rooftop was blowing, and she couldn't help but shiver.

"It's a little cold, put your hat on." Zhao Cheng didn't know when he stood behind her, and helped her lift the hat on her coat and put it on her head, and after wearing it, she seemed to feel a little dissatisfied, and pressed the hat down for her.

Song Huai smiled politely, "Thank you." ”

Zhao Cheng threw the cigarette butt in his hand on the ground and squinted his eyes and looked around, "Are there any clues?" ”

Song Huai was willing to hide his face in the scarf, "You look down." ”

Zhao Cheng squatted down and looked at it carefully for a while, only to find that there were two black things on the ground, but they were the size of a red bean, and the traces were extremely faint, so he couldn't see anything at all.

"This ......," Zhao Cheng looked up at her, "is it a trace left by some building materials or the like?" ”

After all, this is an unfinished rough building, not a hardcover house, and it is inevitable that there will be friction when building a building, so it is not surprising to leave such traces.

"It's not." Song Huaiyuan took a step back, squatted down on one knee, and tentatively stretched out a knuckle from his sleeve, pointing to the trace, "This is a trace formed by ballistic polymer and thermoplastic polyurethane, half a year ago, the designers of THesisCouture used a combination of these two materials as the heel material of their new high heels, the price is not cheap, and the world is limited to 1500 pairs, I remember that the deceased wore on his feet, this pair of shoes." ”

"You still know this?" Zhao Cheng exclaimed.

Song Huai retracted his hand unhurriedly, "Someone took this shoe and asked me to help identify it before, so I was a little impressed." ”

"So, the fourth floor where we found the body is not the first crime scene, this is it."

"Why did the killer bring her here and then take her to the fourth floor? Extra moves, right? ”

Zhao Cheng was surprised, the corners of his mouth rose, "Do you remember that when we arrived at the scene, there were only the footprints of the victim?" ”

"Remember, has something to do with this?"

"Of course." Zhao Cheng stood up, stunned that he was half a head taller than Song Huaiyuan, with excitement between his eyebrows, the wind blew his clothes, and he was wrapped up, "Do you know what the shoe size of Duan Lijuan's secretary is?" ”

"Thirty-seven and a half yards." Song Huai was willing to answer.

Police station.

The atmosphere of the criminal investigation team today is a little weird, especially the captain Shen He, who has a sad face, Song Huai is afraid that he will crush the glass thermos cup in his hand in the next second.

"Xiao Song, this old Zhao has been with you all the time, what kind of medicine do you say he sells in his gourd? What are we doing with an irrelevant person?! ”

In order to prevent the dangerous aura on his body from affecting him, Song Huai moved to the side quietly, "She is not an irrelevant person, she is the murderer." ”

"What?" The wolfberry tea in Shen He's mouth almost didn't squirt out, "Murderer? You say this woman? Why did she kill Duan Lijuan? Isn't that nonsense! ”

"I don't know, Zhao Cheng said that." She thought for a moment and added, "It should be true." ”

Although Zhao Cheng was excited to visit along the way, and didn't explain to her, she just felt that this uncle should be credible for no reason, at least more credible than the one next to her.

"Uncle, drink less wolfberries in the future, it will be easy to get angry."

“？？？？” Shen He looked at Song Huaiyuan blankly, he originally wanted to refute, but he couldn't get angry.

The team members next to them were shocked by Song Huaiyuan's words, and then tried very hard to hold back their laughter.

originally thought that this girl was a pure and harmless little sheep, but who knew that this opening was not shocking and endless!

Different from the weird atmosphere here, in the interrogation room, Zhao Cheng leaned on a chair, clasped his hands on his chest, and looked idly at the woman in professional clothes opposite, "What's your name?" ”

The woman looked at him decently and replied timidly, "Wang Qian." ”

"Good name." Zhao Cheng knocked on his arm, "Tell me why you killed Duan Lijuan, right?" ”

Wang Qian's eyes widened, and his body suddenly leaned forward, "Kill Mr. Duan?" I didn't do it! ”

"If you're not mistaken, your shoes are supposed to be size 37, right?" Zhao Cheng looked at her indifferently.

Wang Qian subconsciously retracted his feet, "What's wrong with 37 yards?" ”

"The shoes on Duan Lijuan's feet are also size 37, but are they a little crowded when you put them on? Because I checked, that pair of shoes did not produce niche shoe sizes, so Duan Lijuan could only buy a pair of size 37 shoes, and then asked someone to help her change them. Zhao Cheng pointed to his shoes, "At the toe of the shoe, a piece of memory foam is stuffed." ”

"What does this have to do with me?" Wang Qian's voice was much quieter.

"Don't worry, since a pair of size 37 shoes is stuffed with something inside, the shoes must be small, what will a person do when the shoes that she thought should be suitable for her feet suddenly become smaller, but she can't help but wear them?" Zhao Cheng said, got up from the chair, approached Wang Qian, propped his hands on her chair, and looked at her condescendingly, "It must be hard to squeeze in, at this time, high heels will grind your feet, especially when you carry a person down the stairs, it will definitely grind your feet even more." ”

Wang Qian looked up at him, his voice heavy and steady, "What do you want to say?" ”

"Grinding your feet, you will definitely leave dandruff tissue, we have already tested it just now, the dander tissue behind Duan Lijuan's heel is actually exactly the same as your DNA, what's going on?"
