The task force was very efficient, and it only took half a day to find the suspect who had left multiple shoe prints and fingerprints in the rental house in the towns around Jinshui County.

As Gu Song speculated, the suspect was Xiao Jing's father, named Tang Yongsheng, 42 years old this year, a hardware store owner with only a beginner level of Chinese. He and his wife only have an only daughter, Xiao Jing, and they have always loved Xiao Jing. Although their family's economic conditions are not too wealthy, they also do their best to provide Xiaojing with a happy growth environment.

Xiao Jing's tragic death is undoubtedly a terrible disaster comparable to the end of the world for this simple and peaceful small family.

22-year-old Xiaojing, with the age of flowers, simple, cute, brave, kind, a beautiful life has just begun, but because of the mistake of loving a man, he lost his young life in fear and pain.

When the investigators found Tang Yongsheng at home and asked him to cooperate with the collection of shoe prints and fingerprints, he did not show the slightest surprise, nor did he make any gestures of resistance, as if he had long expected that he would usher in such an ending.

The moment he put on the handcuffs, he exhaled a long breath of relief, and in the face of his wife's hysterical roars and questions, he didn't explain anything, just said "I'm sorry" apologetically, and followed the arresting police out of the house without looking back.

In the interrogation room of the county public security bureau, Tang Yongsheng calmly sat in the interrogation chair with an expression of death on his face. Perhaps when he learned that his daughter had passed away, his heart also died, and he followed his daughter into the boundless dark world.

Qiao Sheng is also a father who loves his daughter very much, and he can fully understand Tang Yongsheng's pain of losing his daughter. He looked sympathetically at the suspect sitting across from him, and his questioning was much softer than usual. "Tang Yongsheng, do you know why we arrested you?"

"Yes, I know." Tang Yongsheng bravely looked directly into Qiao Sheng's eyes and replied very cheerfully.

"Okay, so let's talk about it, when did you go to the rental house? Why go there? What were you doing there? ”

"I heard that my daughter's killer lived in that rental house. In order to avenge my daughter, at about 10 o'clock in the night on July 17, I found the house according to the address on the note. I didn't prepare a murder weapon in advance, so I picked up a broken rock on the side of the road to use as a weapon. When Xiao Jing was killed, he was stoned in the head by the murderer, and then he was brutally killed, and I want to take revenge on the murderer in the same way.

"I came to the front of the room, knocked on the door a few times, and she opened it without asking who I was. I saw that the opportunity had come, and without saying a word, I broke into her house. The woman was tall and thin, and she had a lot of strength, and she saw that I was not a good person, and she even started to fight with me. I stoned her head, and within a few moments she was dizzy and unable to resist.

"I didn't kill her on the spot, because I wasn't willing to let her go to Hades so soon. After subduing her, I carried her on my shoulders, left the rental house, and used a borrowed farm tricycle to pull her back to her hometown in the countryside......" Tang Yongsheng said here and suddenly stopped, with a look of fear on his originally calm face.

"What happened next?" Qiao Sheng reminded him to continue.

Tang Yongsheng swallowed his saliva, endured the nausea in his stomach and confessed the crime he committed against Jiang Ran. "I locked the woman in the cellar of my hometown and woke her up with cold water. She glared in horror and asked me who I was and why I had kidnapped her. I said that I was Xiao Jing's father and asked her if she was the murderer of Xiao Jing. I didn't expect her to admit it so readily, and I didn't expect her to have no remorse for the murder, and scolded my daughter for being a slut and a shameless junior, as if my daughter should die in that way.

"At that moment I was so dizzy that I grabbed the pickaxe from the cellar and slammed it at her. I didn't think I'd kill her so soon, my original plan was to cut open her stomach, pull out her intestines, and let her die in excruciating pain and fear. But I lost my mind at that time, I couldn't care about anything, I just wanted to vent the hatred in my heart. I don't know how many times I hit the woman with my pickaxe, but by the time I came to my senses, she was ...... It's already out of breath......"

"What did you do with the body after killing that woman?" Qiao Sheng asked.

Tang Yongsheng shook his head and said, "I didn't deal with it, the body is still in the cellar." Our old house is abandoned and no one lives there, and no one usually goes there. ”

"Good." Qiao Sheng was very satisfied with Tang Yongsheng's answer. He turned his head and glanced at Gu Song, who nodded knowingly and began the focus of today's interrogation. "Tang Yongsheng, please answer truthfully, who revealed the information that 'Jiang Ran is the murderer of Xiao Jing' to you?"

"Luo Tong told me." Tang Yongsheng replied without thinking.

"You just mentioned that you found the house Jiang Ran rented according to the address on the note, who gave you that address?"

"The address was also given by Luo Tong."

"Did Luo Tong instigate you to kill Jiang Ran?"

"What?" Hearing this question, Tang Yongsheng was stunned for a moment, looked at Gu Song in surprise and said, "No, Luo Tong didn't instigate me to kill someone, I just couldn't watch the murderer who killed my daughter go unpunished, so I decided to kill the female devil with my own hands." ”

"Now that you know who the killer is, why didn't you call the police? Why not use the law to solve this matter? ”

"Because ......" Tang Yongsheng licked his dry lips and replied helplessly, "Because the murderer has just come out of the psychiatric hospital, in case she kills my daughter while she has a seizure, it will be useless for me to call the police!" ”

"Luo Tong also told you about this?" Gu Song asked with a frown. Seeing Tang Yongsheng nodding and admitting, he was almost sure that the poor father in front of him was being used by Luo Tong. Before entering the interrogation room, he seriously suspected that this case was inextricably linked to Luo Tong, because Jiang Ran's identity information could only leak out of Luo Tong's mouth.

Luo Tong also had a criminal motive to kill Jiang Ran, but he didn't do it himself, but took advantage of Tang Yongsheng's psychology of wanting to avenge his daughter, and "gave away" the opportunity for revenge.

He firmly believes that Tang Yongsheng's crime of intentional homicide has nothing or little to do with him, and even if the police investigate him, he will not be punished too severely.

Tang Yongsheng has anti-investigation ability, and he doesn't care if he will be caught by the police. On the contrary, if he tells Tang Yongsheng how to clean up the crime scene and how to destroy the corpse, then he has really become an accomplice to the murderer.

It's a pity that the idea of "borrowing a knife to kill someone" is just Gu Song's speculation, and there is no evidence. He was even more worried that with Jiang Ran's death, a terrible truth might never be confirmed......
