The two of them finished breakfast and returned to the sub-bureau, there was no progress in the investigation of Hu Zhihai, and it happened that the colleagues who rushed to Liulishan City overnight last night brought Fang Xu back, looking at the two of them with eager eyes, they simply solved the case by the way.

Opening the door of the interrogation room, Fang Xu was a little sluggish.

Suddenly, he was brought back from Liulishan City overnight by a group of policemen who fell from the sky, and he didn't even tell him for a reason. After that, Fang Xu, who had been imprisoned in this room and had not slept all night, was in a worried mood, and his natural state was not much better.

Fang Xu, 21 years old, is a third-year student at the Department of Medicine of Sun Yat-sen University. He has a perverse personality and good grades, so he can be regarded as an honor student. ”

Outside the interrogation room, Fang Qin handed Fang Xu's personal information to Xu Ziqian and made a brief introduction.

Xu Ziqian nodded, took a careful look, gave Ding Xiaoqian, and pushed the door in.

Fang Xu heard the voice, raised his head and looked at the two people who pushed the door in, his eyes were a little red.

"It's you, why did you arrest me? The police are amazing, huh? Fang Xu wanted to get up excitedly, but was held down by the person behind him.

"Hu Tingting is dead." Xu Ziqian's short words made Fang Xu stunned, his face instantly became bloodless, his eyes fell on Xu Ziqian's face sluggishly, and his lips moved slightly: "What...... How can it be? ”

Two or three seconds later, he immediately shouted, "What are you doing with me when she's dead?" What does it have to do with me? ”

"You had a conflict with the deceased before your death, and we ask you to come back and cooperate with the investigation." Ding Xiaoqian spoke on the side.

Fang Xu snorted twice unconvinced, and said with some yin and yang weirdness: "What do you mean?" Had there been a conflict, and she died, was it me who did it? Don't you all talk about evidence? What about the evidence? I don't have any evidence to come with me, and I also understand the law! I still say that she slapped me before, and now I have a headache, I need to see a doctor, I want to have an injury. ”

He shouted a little scoundrelly, Xu Ziqian and Ding Xiaoqian just looked at him silently, letting him toss.

Fang Xu tossed for a while, seeing that the other party was unmoved, he also felt a little bored, he sat down stupidly, without his previous arrogance, his legs trembled slightly, and even his voice was a little uncontrollable unstable: "She...... Hu Tingting, how did she die? ”

"Where did you go after the conflict with Hu Tingting yesterday?"

"You guys, do you suspect I did it?" Fang Xu cautiously stared at the faces of Xu Ziqian and Ding Xiaoqian, but it was a pity that the two of them seemed to be equally expressionless when they discussed, so that Fang Xu couldn't see any emotion.

"Forget it, it's about the same as usual. Go out and go on the net for a while and eat something. Fang Xu said that he forgot first, and immediately changed his words after facing Xu Ziqian's emotionless eyes.

"Where are you between half past seven and nine in the evening?"

Fang Xu was silent and didn't answer, and only after a while did he ask tentatively: "That's my personal **, do I have the right not to answer?" ”

"If you don't answer, you don't cooperate with our work, and we have every reason to suspect that you have something to do with this murder of Hu Tingting."

Ding Xiaoqian's words made Fang Xu's legs tremble even more, and his speech became stammering: "Why, why?" Why does she have to do something with me when she's dead? I'm going to be friends with her, but I'm not going to kill someone just because she won't give me a slap, right? You're wronging me, I'm a man anyway, so I can't get along with a girl because of this, right? ”

Under Ding Xiaoqian's calm gaze, Fang Xu felt a sense of weakness, as if all the thoughts in his heart could be seen through by those eyes.

He finally lowered his head, didn't dare to look at Ding Xiaoqian, and his voice became extremely small: "I thought about making some trouble for her, after all, I can't be ......beaten for nothing."

Speaking of this, he hurriedly raised his head and defended: "But it's really not me, you must find out!" ”

"Fang Xu, now your suspicion is the greatest, if you really feel that you have been wronged, you had better cooperate with our work, so that you can clear your suspicion. Who can prove what the hell you were doing between half past seven and nine last night? Ding Xiaoqian suddenly said.

Fang Xu looked at Ding Xiaoqian seriously for a while, and said helplessly: "I'm really fine, and I don't have any witnesses, what do you want me to say?" ”

The first interrogation was very unsmooth, and Xu Ziqian and Ding Xiaoqian couldn't do anything about Fang Xu's non-cooperation.

"This is a hob meat, and if you want to break through his psychological defense, you need to find another way." In the monitoring room, which was separated from the interrogation room by a wall, the director of the sub-bureau spoke slowly.

Fang Xu is very suspicious, and all the clues point to him. He is so uncooperative, and he has always refused to say where he is, which obviously makes people even more suspicious.

But without conclusive evidence, Fang Xu could only be detained for 24 hours at most, and then he had to be released. Seeing that the time was approaching little by little, everyone felt a little irritated.

When Fang Xu was let go, he walked in a hurry, as if he was afraid that he would be caught again if he turned around. It wasn't until he ran away that he put his mind at ease, but when he turned around, he raised his middle finger in the direction of the police station, making the person standing at the door shake his head for a while.

"How can a person with this kind of personality learn professional knowledge so well, he is simply a ruffian! Except for studying better, you can't do anything else! Fang Qin said with some anger.

Ding Xiaoqian glanced at her, Fang Qin accidentally scolded her just now. Although she is not a ruffian and hooligan character, she seems to be nothing but a good learner.

Fortunately, the situation was not particularly bad, and several colleagues who went to Hu Tingting's bedroom to collect information returned and brought back a few pieces of useful information.

One of them: Hu Tingting will leave school every weekend and return on Monday, after inquiring about Hu Tingting's home, she goes home once a month and does not go home the rest of the time.

Second: Hu Tingting's mobile phone call record query results show that she has frequent contact with a person named Dong Wanxing whose name is Dong Wanxing, and after telephone communication, the other party is a student of Xiaoshan Conservatory of Music, also in his third year, and Hu Tingting met at the Xiaoshan Music and Culture Festival, because they have common hobbies and majors, they chatted closely.

Third: Hu Tingting's opening record of the hotel in the city shows that she will open a room in a hotel called Blue Ocean almost every weekend, but every time the opening record shows that she is alone.

These clues make people's eyes shine, but they are immediately confused. When she goes to open a house alone, why doesn't she live at the school? According to the feedback of her dormitory classmates, she has a good relationship with the people in the dormitory, and there is no need to go to the hotel to open a room.

"Contact Blue Ocean Hotel, and we'll go over and copy the surveillance video." Xu Ziqian suddenly spoke, and faintly became the leader of this group of people.

The head of the sub-bureau who was replaced did not have any negative feelings, and waved his hand to indicate that he would hurry up and carry it out.

After contacting the Blue Ocean Hotel, it was still Xu Ziqian and Ding Xiaoqian who went over in Fang Qin's car, carrying a mobile hard drive with them. The person in charge of the blue ocean came forward to receive them in person, and very cooperatively asked them to copy the video of Hu Tingting's opening day, and then sent them all the way out of the door.

Hu Tingting's first opening time was in May of the second semester of her sophomore year, which is the second month after the Xiaoshan Music and Culture Festival. Until October, as of the weekend of the week before Hu Tingting's death, there were intermittent records.

Ding Xiaoqian called for takeout, hot sauerkraut buns and warm two-rice porridge. When the takeaway was delivered, she was still in the video room struggling with the videos that came back from her back. Xu Ziqian happened to meet him when he came back from outside, and he took it directly and sent it to the video room.

Xu Ziqian pressed the pause button, took off Ding Xiaoqian's headphones and said, "Eat first, and watch later." ”

Ding Xiaoqian stretched his arms to relieve the aches and pains in his body, leaned over to the table, and looked at the food but felt that he had no appetite.

Xu Ziqian pulled out a chair and sat down at the table, and when he saw the food, his expression added a bit of color.

"You like to eat this too?" He pointed to the sauerkraut buns.

Ding Xiaoqian was silent and handed Xu Ziqian's share to him.

Xu Ziqian asked while eating, "Have you found any useful clues?" ”

Ding Xiaoqian shook his head, and his eating movements were very slow, as if it was difficult to swallow: "Not yet, I have seen the end of June, I hope that the latter ones can have some useful value." The previous videos were all hotels where Hu Tingting went alone, and there was no one else. ”

Xu Ziqian took a sip of porridge and suddenly said, "Did you miss the time when Hu Tingting checked in, did you look back?" ”

Ding Xiaoqian paused, raised his head and asked, "You mean ......?"

Xu Ziqian nodded.

Ding Xiaoqian immediately pushed the food in front of him, turned around and prepared to start work immediately.

Xu Ziqian hurriedly pulled her arm: "Eat first!" ”

After Xu Ziqian's reminder, Ding Xiaoqian paid special attention to the video after Hu Tingting checked in this time. But Blue Ocean stays in so many people every day, and many people will still stay after Hu Tingting moves in, which has created a lot of trouble for the progress of the case.

Xu Ziqian looked at Ding Xiaoqian, whose eyes were red, and persuaded her several times but failed to let her go to rest first. In the end, the two agreed that it was okay not to go back to sleep, but they had to sleep in the video room for a while.

The four chairs were divided equally between the two, and their postures were twisted into the chairs, and their eyes were closed.

The hands of the wall clock on the wall had pointed to 5:20 in the morning, and Ding Xiaoqian, who had not slept all night, stared at the image on the projector in front of him with red eyes, as if he wanted to eat people.

Suddenly, she quickly pressed the pause button, then carefully rotated the back button slightly, and then pressed play. After that, pause, rewind, and play slowly.

"Found it!" She cheered softly, clenched her fists in front of her chest, excitedly took off her headphones, turned and stood up violently, and it felt like the world was spinning.

Xu Ziqian was woken up by a bang. It was extremely uncomfortable to sleep in the chair, and he had long hands and feet, and he couldn't stretch them at all, and he was barely dazed, when he heard the bang of something being knocked over, and he suddenly opened his eyes in shock.

Ding Xiaoqian was not far from him, lying on the ground on his side, his eyes closed.
