The next morning, I got up and washed up, had breakfast, and Ling Fei and I left Yejiawu directly, and drove to the suburban middle school, ready to investigate the scene again, by the way, I asked the security guard about the situation, after all, the security guard was watching the gate, and his discovery may be the most comprehensive. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

Our car quickly arrived at the gate of the suburban middle school, this time the gate was closed, and the notice of the school's suspension of work was also posted on the door, I said hello at the observation window of the security guard, the security guard saw that it was a police car, so he used the remote control to open the electric gate, I drove the car in, parked the car, and walked to the security room.

The security guard is a middle-aged uncle, he looks quite good, his figure and gestures look like he is from a military background, I said: "Comrade security guard, we are forensic doctors of the criminal police team, I want to know about some situations, did you see some abnormal situations yesterday." ”

The security guard said embarrassedly: "There were too many people after school yesterday, parents squeezed in and out, battery cars were piled up, and then the students got out of class, and there were more people, I really couldn't control it, so I didn't see the abnormal situation you said at all." ”

I said, "I understand, what I want to ask is Tao Ling?" ”

The security guard said, "Which Tao Ling?" ”

I said, "It's the Tao Ling classmate who reported to you the death of Teacher Ke Ying." ”

The security guard said, "Oh, that's that classmate, she ran to me in a panic, saying that she saw Teacher Ke Ying killed in the office. ”

I said, "Did she mean that Teacher Ke Ying was killed in the office?" ”

The security guard said, "Yes, that's what she said. ”

I felt a sigh in my heart, so Tao Ling saw the process of Teacher Ke Ying being killed? I quickly corrected my thoughts, that is not necessarily, it may be that the child's expression is inaccurate, but, at least one point, Tao Ling must have seen the corpse of Teacher Ke Ying.

I continued to ask the security guard, "Then you went to the third floor later, right?" ”

The security guard said anxiously, "Then how can you not go?" When I heard Tao Ling say this, I immediately ran upstairs, and what I saw later was what you saw, and I promised I hadn't gone in. ”

I said, "Was the door open when you went up?" ”

The security guard said, "No, the door is closed, but it's not locked, I pushed open the door to find Teacher Ke Ying's body." ”

I nodded secretly and motioned for Ling Fei to take off the security guard's shoes and check if there were blood stains on the soles. Ling Fei quickly took out some reagents and tools from the investigation box and tested them on the security guard's shoes for bloodstains.

I took advantage of the gap between the security guard taking off his shoes and sitting there, and continued to ask him, "Have you seen the shoes that Tao Ling is wearing?" ”

The security guard scratched his head and said, "This, I really can't remember, when I saw her running over in a panic, I felt that something was wrong, and I didn't pay attention to her shoes." ”

After Ling Fei finished checking and confirming that there was no blood on the soles of the security guard's shoes, we returned the shoes to the security guard, and when the security guard put on his shoes, I motioned for him to go to the third floor to reopen Teacher Ke Ying's office for us.

The second re-investigation of the scene, the feeling is different, although the body is gone, and Hou Yuting has been made a mess everywhere, but now I am here with questions, and the research is of course in-depth to a level.

I'm thinking, if the door was closed at that time, then it would be like this, the door was closed by Tao Ling, Tao Ling closed the door after seeing the corpse of Teacher Ke Ying, and then went to report to the security guard, although it works logically, but for a seventh-grade girl, this is not very commonsense, the security guard said that she was in a panic to report to him, since she was in a panic, how could she go to close the door after seeing Teacher Ke Ying's body? And she said that it was killed, if it was not a slip of the tongue, it was not just the sight of the body, but most likely the knife that saw the chest.

This Tao Ling, at present, there is definitely work to do, Hou Yuting yesterday from the scene extracted the children's sneaker shoe print is located next to Ke Ying's seat, if it is confirmed that it has just been mopped to the ground, then the value of the children's sneaker shoe print is very large, although it can not be directly compared, make the same identification, but at least it shows that there are students entering, the interval between the release and the killing of Ke Ying teacher is very short, during this period, it is very likely that students will enter, as for whether it is Tao Ling, it depends on what shoes Tao Ling wore yesterday, If Tao Ling did wear sneakers yesterday, then it feels like the smell is getting bigger and bigger.

I stood at Ms. Ke Ying's desk, and I realized the location where Hou Yuting extracted the shoe print yesterday, what does this mean? What else can be done? I think Hou Yuting must have reported to Liu Da, and Liu Da will definitely go to Tao Ling to verify these details.

I walked around the scene for a long time, thinking about these questions in my head, and Ling Fei also carefully observed various parts of the scene, extracting some physical evidence from time to time.

After about an hour, I said to Ling Fei, "You're almost, aren't you?" Or shall we go to Tao Ling's house and have a look? ”

Tao Ling's home is across the road from the school gate, and I saw that it was difficult for the car to drive in, so I walked along the street with Ling Fei and Ling Fei carrying a survey box.

Tao Ling's house is still easy to find, we walked through a small block, turned through the side door of a supermarket, and saw her house number.

I was about to go up the stairs when I saw Liu Da standing there, Liu Da saw me coming, and hurriedly said, "Su San, come here, you are needed here." ”

I followed Liu Da to the corner, Liu Da lowered his voice and said: "Tao Ling, this little girl, may have been scared stupid, she refused to say a word for a long time, I really can't help her, you see if you try it as a police sister, will she speak?" ”

I said, "You five big and three rough must have scared her out, I'll try it later." ”

Tao Ling's home is on the second floor, and the houses here are all three-story small buildings, which were funded by local residents and then rented out to these migrant workers.

I climbed up to the second floor, the door of Tao Ling's house was open, Tao Ling was sitting on a small bench, wearing a pair of sandals on his feet, a male policeman was doing persuasion work there, and a man sitting next to him, probably Tao Ling's father, he looked thin, as if he had been sick for a long time, he saw me come in, and stood up helplessly.

I said to the policeman, "Can you go out for a while?" ”

The policeman probably wanted to go out a long time ago, and when he saw me say this, he got up and said hello and left.

I sat down next to Tao Ling and pulled Tao Ling's hand, Tao Ling did not resist, I took her hand and put it on my left hand, which was a pair of immature hands, long fingers, if this child grew up in other families, maybe he would be a good piano seedling.

I said softly, "Tao Ling, I'm your police sister, can you trust me?" ”

Tao Ling didn't speak, but his face was obviously much better-looking, and I said, "Were you on duty yesterday?" ”

Tao Ling nodded, I thought, not bad, at least nodding, but I found that when she nodded, she glanced at her father, as if she was asking for permission to answer.

I asked, "How long do you usually have to be on duty?" ”

Tao Ling glanced at her father again, her father's expression did not change, and she said, "I usually clean up on duty, at most half an hour. ”

I continued to ask, "Then after you cleaned up, went upstairs to report to Teacher Ke Ying?" ”

Tao Ling may have heard the words of Teacher Ke Ying, her small body trembled, she looked at her father, and her father's expression still did not change.

I saw that she was very nervous, so I touched her little hand, but Tao Ling suddenly cried, and I ended the inquiry early as soon as I saw that the situation was not right.

I put down Tao Ling's hand, walked out of the door, and stood in the corridor in front of her house, the policeman just now was standing there smoking, he saw me come out, so he threw away the cigarette butt and greeted me, but my eyes followed his cigarette butt and saw a pair of white children's sneakers leaning on the ground, which still looked wet, obviously freshly washed.

I immediately motioned for Ling Fei to start the test, Ling Fei took out the reagents and tools, and dropped a drop of reagent on the sole of one of the shoes, and I immediately saw Ling Fei's face change.

"Mr. Su, there is a bloodstain reaction on the soles of your shoes!" Even though Ling Fei's voice was very low, I could hear it very clearly.
