At 10 o'clock in the middle of the night, an explosion was suddenly heard in a villa area, and after the sound, a villa began to catch fire. When the fire brigade arrived at the scene, they immediately brought the fire under control, and then immediately reported the case to the criminal police team, because the firefighters determined that the explosion was caused by arson, and the body was found at the scene......

After we were each called to the scene by the captain from our homes, we began to talk to the firefighters about the situation......

"Boss, the firefighters said that the explosion in this villa was caused by the explosion of a car in the garage. The car leaked oil, but the fire was caused by an external force. After Xiao Su finished negotiating with the fire brigade, he immediately explained the situation to the captain.

After I waited for Xiao Su to finish speaking, I said to the captain: "There are two charred corpses in the garage, a man and a woman. But the cause of death was a blunt blow to the back of the head. The two bodies were supposed to be the owners of this villa. However, no objects matching the murder weapon were found at the scene of the explosion. ”

As soon as I finished speaking, a firefighter immediately called us into the villa, because when the fire brigade checked the house, they found a little girl hiding in the bathroom, and the captain immediately asked me and Xiao Su to go over to see what was going on......

Xiao Su and I went into the bathroom of the villa and saw a girl about 15 or 6 years old standing next to a firefighter. The girl looked a little shaky and cried with the makeup on her face.

Xiao Su walked up to the girl and comforted: "It's okay, the fire has been extinguished." Don't be afraid. ”

The little girl asked with a little crying, "Are my parents dead?" ”

Xiao Su and I were stunned after hearing this, but we didn't expect the child to ask her if her parents were dead, which obviously she knew in advance that her parents were in the garage.

I looked at the little girl and said, "Yes, can you tell us about what's going on in your house?" ”

The little girl looked at me with tears in her eyes and said, "I was doing my homework, and I heard the garage door open and knew it was my mom and dad coming back." Then I heard an explosion a little later, and I hid in the bathroom and called 119. ”

As soon as the little girl finished speaking, I asked her to take her to the hospital first, and Xiao Su arranged for the stepping officer to step on the certificate throughout the villa, because we both found a problem......

"She's lying, how can anyone who is neatly dressed and wearing makeup to do homework at home." After leaving the villa, Xiao Su said to me.

I also nodded and said to her, "Well, and I see that her eyes are glazed, she should be taking drugs, and she has just recovered her strength." Let's go, let's go back to the game first. ”

After the two of us finished speaking, we returned to the police station with the captain......

In the police station meeting, Xiao Su had already sorted out the information of the two deceased, and said to us: "The two deceased, a man and a woman, the man's name is Jiao Lijun, and he is the CEO of a steel company. The woman's name is Xu Shuang, unemployed. The two are husband and wife, and they are the owners of that villa. The two have a daughter, the girl who reported the fire alarm, named Jiao Tianqi, 16 years old this year, and is in her first year of high school. ”

After Xiao Su finished speaking, the captain pointed at me and motioned for me to continue.

I said to everyone: "The personnel have collected fingerprints and other clues in the villa, but there are only fingerprints and footprints of this family of three in the villa, and Jiao Tianqi found a few women's hairs in her bedroom, which are a little different from her own hair. The deceased Xu Shuang had short hair, so it cannot be ruled out that a fourth person was present in the villa before the explosion, but Jiao Tianqi has now been sent to the hospital for examination, so he cannot be interrogated for the time being. ”

The captain listened to my words and suddenly said loudly: "Damn, then you didn't say it earlier." There is no way to cross-examine and no further arrangements. It's not up to you to delay, so let's go home. Tomorrow Xiaomei and Xiaosu, you two go to the hospital and ask the little girl. ”

After the captain finished speaking, he left alone, ready to go home and sleep. And Xiao Su and I had to go home separately tonight and agreed to go to the hospital tomorrow......

Early the next morning, after arriving at the hospital, Xiao Su and I contacted Jiao Tianqi's head teacher, and the three of us entered Jiao Tianqi's ward together and began to question Jiao Tianqi.

According to China's regulations on the questioning of minors, if the person being questioned is involved in a homicide case or a major case and cooperates with the police investigation, the guardian of the person being questioned must be present during the police questioning before the questioning can be made. Since Jiao Tianqi's parents had been killed, Xiao Su and I could only ask her homeroom teacher to come over and audit......

In the ward, Xiao Su asked Jiao Tianqi, "Have your parents usually offended anyone?" ”

Jiao Tianqi shook his head and said, "No, but my father is in business, and I often hear him yelling at each other when he is on the phone, and sometimes scolding." ”

After Xiao Su listened to Jiao Tianqi's words, he continued to ask: "Some of your neighbors reacted to us that you have a very bad relationship with your parents and often quarrel, are there any such things?" ”

After listening to Xiao Su's words, the other party obviously said with some emotion: "What do you mean?" Do you suspect that I killed my parents? I can't kill them no matter how much I quarrel with them, that's my own parents. ”

After the other party finished speaking, Xiao Su looked at me and seemed to ask me if I would continue to ask next.

After I glanced at Xiao Su, I said to Jiao Tianqi, "How much did you swallow yesterday?" ”

Jiao Tianqi was still a child after all, and he didn't have much defense, so he subconsciously blurted out: "Three." ”

When she finished speaking, she also felt as if she had missed something, so she deduced that she had a headache and wanted to rest. Xiao Su and I had no choice but to leave the ward first......

After leaving the ward, Xiao Su said to me, "This girl has a problem!" If her parents died, she would be the rightful heir to the property, and many children now do things selfishly and impulsively. So she's also very suspicious. ”

I listened to Xiao Su's words, and I also felt that her analysis was very logical, but now this girl doesn't tell the truth at all, which is really a bit of a headache.

I thought for a while, and said to Xiao Su: "You go in first and continue to ask her, I'll do something, twenty minutes at most, and I'll be back immediately." ”

After listening to this, Xiao Su glared at me with a small mouth, and continued to enter the ward to start a new round of questioning......

A short time later, I walked into the room with a piece of equipment.

After entering the ward, I said to Jiao Tianqi, "Plug it in, this is a lie detector." When I ask you, you answer. If you lie, the machine will think. ”

After I finished speaking, I pasted a few threads on several corresponding positions of Jiao Tianqi.

After I got it done, I said to Jiao Tianqi, "You can't lie now. Of course, I'll know if you tell a lie, so let's get started. ”

After I finished speaking, Jiao Tianqi took a deep breath and nodded at me. Seeing that she had no objections, I began to prepare to cross-examine her personally......
