At ten o'clock in the evening, a woman's shrill cry broke the calm of the night at Zhaoguan University.

Li Yaotai and Zhang Xiang's squad received the report and hurriedly came to the scene of the crime, and there was still a female corpse in the cordon.

The corpse was wearing a white long-sleeved babydoll collared blouse and a black midi irregular solid skirt with the top faded above the breasts and the bottom garment down to the knees.

The fall from the building caused a lot of trauma to her head, and the blood splashed her all over her body, stained her neckline and sleeves red, and also stained the campus of Zhaoguan University.

Li Yaotai looked at the bloodstained face of the corpse through the light, and felt very familiar, and after thinking carefully for a while, Li Yaotai exclaimed: "Isn't this the girl who shouted during the day!"

Zhang Yu glanced at Li Yaotai, and then shouted: "Who reported the case?" ”

A man in a suit and leather shoes who looked young was outside the cordon, signaling to Zhang Xiang that he had something to say, Zhang Xiang walked over, looked at the man and said, "You reported the case?" ”

The man shook his head and handed Zhang a business card.

"I am the president of Zhaoguan University, and the first person to find the body was a sophomore in our school, she was so frightened that she may not be able to cooperate with the investigation now, so I will ask you to come over and interrogate when she calms down a little. The person who reported the incident was a school worker who rushed to hear the news, and he is now waiting for questioning in the principal's office. ”

"The surveillance here in the teaching building will help to adjust, by the way, the school worker who found the body this morning is the same person who reported the crime tonight?"

The principal nodded and replied, "Yes, because our school staff is on duty for one day and then shifts, and it happens to be Li Nian on duty today." ”

As he was talking, Li Yaotai ran over and interrupted the conversation between the two, and said to Zhang Yu, "Team Zhang, Senior Sister Ban asked you to come over." ”

Zhang Yu nodded, motioned to the principal to wait a moment, and then walked towards the class sleeve.

After examining the body, the squad stood up.

"The time of death was less than an hour, part of the nail of the index finger and ring finger of the right hand was missing, and there were obvious strangulation marks on the neck."

Ban Sleeve paused, then continued.

"It's basically the same as Zhuo Yuan's strangulation marks, and there are new lacerations on the lower body, but after being violently washed, there should still be nothing to extract. It is not possible to tell whether it was a death from a fall or a death by suffocation, but this is probably the case. ”

Zhang Xiang looked up in the direction of the roof.

"I'll have the body shipped back to you in a moment. Xiao Liu Xiaozhang, you two bring the student who found the body and the school worker who reported the case back for interrogation. Li Yaotai, you come with me to the top of the building to take a look. ”

After speaking, he walked into the teaching building, and Li Yaotai hurriedly trotted to follow.

Roof.

What catches your eye is a mess of objects, as if to announce how fierce the fight has been here.

Zhang Yu walked to the fence and squatted down, observing little by little along the wall, and then he stopped in one place.

After looking at it for a while, Zhang Yu said to Li Yaotai: "Come here and take a picture of the scratches here, and then collect these two nail fragments." ”

Li Yaotai, who was looking down to search the ground, secretly glanced at Zhang Xiang and said, "Won't you accept it yourself?" ”

Zhang Yu didn't raise his head and said, "Don't talk nonsense." ”

Li Yaotai hesitated, but reluctantly took out the evidence bag to collect the nail fragments.

Zhang Xiang continued to search carefully, he passed his hand through the gap in a pile of discarded steel, picked up the brooch that had fallen in the corner, and then stood up and looked carefully at the faint moonlight.

After Li Yaotai put away the physical evidence bag, he also hurried over to take a look. After seeing the brooch in Zhang Xiang's hand clearly, Li Yaotai froze in place.

"This is ......"

Zhang Yu glanced back at Li Yaotai strangely, shook the brooch in his hand, and asked, "Have you seen it?" ”

Li Yaotai took a deep breath, as if he had made up his mind, "This brooch was given to Du Xianhuai by me, I made it for a month, it is unique in this world, I will not admit my mistake." ”

Zhang Yu raised his eyebrows, threw the brooch to Li Yaotai, and said, "Let's go, go find your boyfriend." Then he took the lead and went downstairs.

Li Yaotai looked down at the brooch in his hand, was silent for a while, and hurriedly caught up with Zhang Xiang's pace.

Li Yaotai and Zhang Yu quickly found Du Huihuai's office, but the lights had been turned off and the door had been locked.

The two had no choice but to go to the principal's office again, but fortunately the principal had not left.

Zhang Xiang knocked on the door, and then said loudly, "Headmaster, excuse me." ”

The principal raised his head in response, and saw that it was Zhang Xiang and the others, so he hurriedly stood up, "Officer Zhang, what is the matter with you coming?" Come in, come in. ”

Zhang Yu waved his hand, "I won't go in, we just want to ask if you know where Professor Du Huaidu is now?" ”

"Professor Du, he just discussed with me about the issue of insurance students, and he just left not long ago. I left at about half past ten. ”

Zhang Xiang said thank you, and then dragged Li Yaotai to turn around and leave, and Li Yaotai, who was dragged, pushed Zhang Xiang away in annoyance, and shouted: "Zhang Xiang, you are insane!" What are you going to do? ”

Zhang Xian leaned against the wall with his hands on his shoulders, and asked in arrears: "As Du Xianhuai's girlfriend, you should know where Du Xianhuai's family is, and lead the way in front." ”

Li Yaotai said "viciously": "Follow behind!" ”

Before they knocked on the door of Du Xianhuai's house, the two heard Du Huihuai's exclamations in the house.
