"This, during this time, no one has reported this problem, but because he has a history in this area, there are some rumors!" Principal Zhong's answer was more cautious, he knew that there were some things that could not be concealed from Teacher Lu's death, and he did not dare to doubt the ability of the dictatorship.

"Teacher Luo, can you arrange a few students in the class, and I'll talk to them......" Liu Gang saw that Teacher Luo didn't mean to speak, so he could only start from the students.

"This ...... Team Liu, specifically, I haven't heard of it, but a few days ago, a student reported to me that Tang Xin had been to Teacher Lu's house alone, and I heard that he stayed at home for almost an hour......" Teacher Luo hesitated for a moment before slowly speaking.

"Such an important matter, why didn't you reflect it earlier......" Principal Zhong's face changed on the side.

"Teacher Luo, who reported this news to you? You let her come, I'll talk to her! Liu Gang's eyes lit up slightly, and he already vaguely understood the reason for Teacher Lu's suicide.

"Okay, I'll call her over!" Teacher Luo Yubing nodded.

"Principal Zhong, can you find a separate lounge!" At this time, class is also over, and a teacher has already walked in, and it is obvious that there is no more information in this place.

"Okay, Brigade Liu, please come with me!" Principal Zhong took Liu Gang out of the office, Luo Yubing also walked out of the classroom with a somewhat beautiful girl, Principal Zhong took them to a small room, the room was very simple, only a sofa, a writing desk, and a chair.

"Principal Zhong, Teacher Luo, you guys are busy with your business, I'll talk to her alone!" Liu Gang himself used to be a student, and he knew that students had a natural defensive psychology against teachers, and there were some things that he didn't dare to say.

"Okay!" The two hurriedly retreated.

"Hello, I'm Liu Gang, the captain of the Criminal Police Brigade, and I want to know something from you." When the two of them went out, Liu Gang officially looked at the girl in front of him, the girl was only fifteen or sixteen years old, she looked quite beautiful, and her clothes were quite trendy.

"Captain Liu, my name is Liu Qi, the deputy squad leader of the third class of the first year of high school!" The girl stared at Liu Gang curiously with a pair of big smart eyes, but there was no timidity or fear that ordinary people had when they saw the police, and some were purely curious.

"Tang Xin is your classmate, right?" Liu Gang asked seemingly casually.

"Well, we've been classmates since junior high school. Classmates for four years. The girl nodded.

"On the day Tang Xin died, do you still have an impression?"

"Yes, I was too scared to go home when I heard that she had been killed, and until now, my family has come to pick me up. How can there be no impression. The girl patted her chest a little exaggeratedly, looking afraid, but there was no look of fear.

"You don't have a very good relationship with Tang Xin!" Liu Gang noticed that when it came to Tang Xin, the girl did not have any emotional fluctuations, nor was she a little sad or indignant, as a four-year classmate, this was obviously very abnormal.

"How do you know?" The girl stared at Liu Gang with wide eyes.

"On the day Tang Xin was killed, was there a math class?" Liu Gang did not answer the girl's question.

"It's math class in the afternoon, and I don't know which bastard who was thundered by the sky actually killed Teacher Lu." Speaking of Teacher Lu, the girl Liu Qi had an extremely heartbroken expression.

"Listen to your Teacher Luo, have you reported that Tang Xin went to Teacher Lu's house?"

"Well, there is such a thing, it was a self-study class, there was no teacher, I quietly sneaked out to buy things, only to find that she entered Teacher Lu's house, until the end of the self-study class, and did not come back after school, it must be this little vixen who seduced Teacher Lu." There was a look of disdain on the girl's face.

"How did you take the class on the day Tang Xin was killed, from leaving home in the morning to returning home in the evening, including the approximate time, you tell me!" At this time, Liu Gang naturally mainly investigated Tang Xin's case, and it was necessary for him to restore the situation of the day, Tang Xin had a surname relationship with two people that day, so the problem became much more complicated.

"That day, specifically, I have to look at the class schedule......" Liu Qi opened the small bag on his body, opened it, looked at it for a while, and then began to speak, "We usually get up at six o'clock, leave home at half past six, go to school at about six forty to participate in morning self-study, eat breakfast at seven twenty, start class at eight o'clock, and read for twenty minutes in the morning...... I didn't go home at twelve o'clock at noon to eat, and after eating, I started to read and review......"

"You don't leave school from the time you enter the school in the morning until ten o'clock in the evening?" Liu Gang listened very carefully.

"Well, you are not allowed to leave! If you want to leave the school, you must have a leave slip! ”

"Then for the break after lunch and dinner, if you want to leave the class, you don't need to ask for leave, right?"

"This is unnecessary, as long as you don't leave school, you don't need to ask for leave!"

"Tang Xin's whereabouts that day, can you roughly remember it?" From Liu Qi's words, Liu Gang has basically been able to determine that Liu Qi admires the mathematics teacher Teacher Lu very much, but there is a contradiction with Tang Xin, which must make Liu Qi pay attention to Tang Xin's actions.

After dinner that day, there was no one in the classroom, and she didn't come in until it was half an hour of self-study in the evening! At that time, I came in with Mr. Lu! Sure enough, Liu Qi casually told Tang Xin's whereabouts that day.

"Are you sure?" Liu Gang was in good spirits.

"Of course I can, I'm the deputy class leader, and I take attendance, if it weren't for Teacher Lu all the way, I would definitely give her a truancy, fifteen minutes late, that's absenteeism."

"Thank you, Liu Qi!" Liu Gang stood up.

"Captain Liu, you must catch the murderer who killed Teacher Lu......" Before leaving, Liu Qi still did not forget to remind Liu Gang.

Out of the lounge, Liu Gang quickly walked to the school's family area, at this time, he also vaguely had a vein, this Lu Mingxi should be the second person who had a relationship with Tang Xin that day, or rather, it was he who had a surname relationship with Tang Xin that day, and Tang Xin was killed that night, which made him feel huge pressure, and he committed suicide because of this.

"Brigade Liu, it can already be concluded that this is a suicide case!" Returning to the scene of the crime again, Kang Boqi was still busy, saw Liu Gang, nodded, but the answer was very positive.

"Captain Kang, you compare the semen residue from Tang Xin's case with this person." Liu Gang nodded, since he suspected that Lu Mingxi was the second person to have a surname relationship with Tang Xin, he naturally had to make sure.

"Oh, okay!" Compaq was slightly surprised.

"Brigade Liu, do you suspect that this Lu Mingxi is the second suspect in Tang Xin's case......" Luo Gangran's eyes suddenly lit up.

"Sort of! Are there any pictures in the house or anything? Although Liu Gang never regarded Lu Mingxi as a criminal suspect, he didn't explain too much, but asked another question, although he took a general look at it just now, he didn't look at it carefully.

"Photos, there are a lot, there are two albums......" Luo Gang quickly entered the room inside, and without much effort, he found two albums, one with the words "A hundred years of good harmony" on the cover, it is estimated that it is a wedding commemorative album, Liu Gang quickly flipped it open, and what caught his eye was a wedding photo, looking at the wedding photo, Liu Gang's eyes lit up slightly, the heroine of the wedding photo, he actually had a familiar feeling, the heroine's body shape looked almost the same as the murderer at the murder scene, Liu Gang flipped through them one by one, basically they were all wedding photos, almost half of them, and they were not wedding photos, but they were all group photos of the two, and there were some ordinary photos.

In the end, Liu Gang's eyes fell on a photo, the woman in the photo, wearing a dark purple dress, the whole person, looking, revealing a bit of nobility and elegance, of course, Liu Gang did not see her nobility or elegance, but the clothes in front of him, but the one seen at the scene of the murder, and the person in the whole photo looked almost no different from the murderer of Tang Xin.

"Come with me to Blacksmith Street!" Liu Gang's spirit suddenly cheered up, took out the photo, and walked out.

Santana quickly drove towards Blacksmith Street, not much effort, but also to Blacksmith Street, parked outside the grocery store, it was four o'clock in the afternoon, almost the hottest time, and there was no business, Boss Sun was sitting in the shade of the tree basking in the sun, saw Liu Gang, he recognized it at a glance, quickly stood up, and enthusiastically stretched out his hand, "Liu Brigade ......"

"Boss Sun, I'm here to bother you again!" Liu Gang shook hands with Boss Sun with a smile.

"Don't bother, don't bother, I'm bored by myself." Boss Sun hurriedly said, for an ordinary person, the captain of the criminal police is undoubtedly a mysterious and somewhat distant figure.

"Boss Sun, look at this person, do you know each other?" Liu Gang took out the photo.

"This is Boss Du...... No, Boss Du should be plump and his face should be rounder...... This person was the gloved woman I saw that night...... Yes, that's her...... These two people are looking for too similar, and they really can't recognize them if they are not careful. Boss Sun screamed suddenly.

"Boss Sun, where is the specific location of Boss Du's shop?" Liu Gang asked.

"It's in the vegetable market over there......" Boss Sun hurriedly said.

"Thank you, Boss Sun!" After thanking Boss Sun, Liu Gang got into the car again and ordered to go to the vegetable market, and in the car, Liu Gang handed the photo to Luo Gangran on the side, "Luo Gangran, take a closer look!" I'll take a good look at it later! ”

It didn't take much effort, Santana stopped outside the vegetable market, the two walked inside, just a few steps, Luo Gangran's eyes immediately fell on a donkey butcher shopkeeper, and at the same time said in Liu Gang's ear, "Liu Brigade, this should be that Du Chunli!" ”
