I got down, put on gloves, and picked up the shoes that Ling Fei was testing, which was a white girl's sneaker, placed in front of Tao Ling's house, it should be Tao Ling's shoes. Pen, fun, pavilion www. biquge。 info I turned the shoes over, the soles were actually washed clean, where Ling Fei dropped the reagent, the color turned blue, this color is a hint that there may be blood stains here, the sensitivity of this reagent is extremely high, no matter how you wash the shoes, as long as the blood stains have adhered before, they can be tested, but this experiment also has the possibility of false positives, so if it is positive, it can only be said that there may be blood, and it cannot be determined that it is definitely blood.

I said softly to Ling Fei: "We will extract this shoe, take it back to the DNA laboratory and examine it carefully, if it is really blood, see whose blood it is." ”

Ling Fei took out two plastic bags for packaging physical evidence from the investigation box, wrapped the shoes, and we hurriedly walked downstairs.

Liu Da was still on the street on the first floor, and I went over to report our findings to him, and also reported Tao Ling's abnormal reaction just now, and Liu Da frowned after hearing it.

Liu Da said: "No, this kid looks quite innocent, did he lie?" ”

I said, "Didn't you say that?" Anything is possible. ”

Liu Da has always doubted everything, but today he didn't even doubt this innocent and lovely seventh-grade girl, anyway, before the results of the experiment came out, I wouldn't let Tao Ling go easily.

On the way back to work, I suddenly thought that Tao Ling had to look at her father's eyes every time she answered a question. Is it just the child's usual habits? Or did her father hint at her before?

We dropped our shoes off at the DNA lab and headed back to the office, where I made another cup of strong coffee to soothe my tired nerves.

Brother Murong walked in, and he said, "Su San, it's hard work, please invite you to dinner at noon." ”

I know that his treats are always in the cafeteria, just to stir-fry two more dishes.

"Okay, Ling Fei, you can go with you." I said to Ling Fei.

We came to the cafeteria together, sat down in a corner by the window, a shredded pepper pork, a dried cabbage, a mushroom loin, okay, just three dishes, the three of us started eating, today's dishes taste quite good, I don't know if I am hungry, or the master has changed.

Brother Murong said while eating, "Is there anything you found at the scene today?" ”

When I saw that he asked about the case, I reported to him about Tao Ling as it was.

After hearing this, Brother Murong stopped eating: "This Tao Ling, has her father done some work?" ”

I said, "Liu Da and they have done work, and they said that Tao Ling's father didn't pick up people yesterday, so they don't know anything about the situation at the scene." ”

Brother Murong said: "That's the case, if you go to Tao Ling's house again, Tao Ling's father will also have to take a regular look." ”

Ling Fei said, "Director Murong, do you mean to look at the soles of his shoes?" ”

Brother Murong said, "Exactly. ”

I was eating and thinking, how could Brother Murong suddenly think of Tao Ling's father? Just listen to me, Tao Ling has to look at her father every time she says a word? But Tao Ling's father never went to school at all.

I suddenly thought, what if he had been? Doesn't it mean that everything is possible? If Tao Ling's father's activity time yesterday afternoon was not confirmed, then Tao Ling's father's words are doubtful, then our forensic doctor wants to intervene, that is, to test Tao Ling's father's soles to see if there are any blood stains, the more I think about it, the more terrible it becomes, and the food in my mouth stops chewing.

"Where do you want to go?" Brother Murong knocked the porcelain bowl with his chopsticks, and the sound of the porcelain bowl was very crisp.

I came back to my senses and said, "No, no, Ling Fei, let's go right away and go to Tao Ling's house again." ”

We hurriedly left the Forensic Research Institute of Yejiawu again, and drove to the suburban middle school, this time it was a familiar road, and the road traffic was unusually smooth, and we arrived at the suburban middle school after a while, I parked the car at the entrance of the suburban middle school, the security guard saw that it was a police car, and immediately opened the school gate, I waved my hand to signal that we did not enter the school, and the security guard closed the gate again, Ling Fei and I still chose to walk, this narrow street or walk fast.

Tao Ling's father is called Tao Jianjian, about forty years old, when Tao Ling was less than three years old, his wife died because of a traffic accident, he himself is now working in a rubber factory in the suburban industrial zone, usually very busy at work, because it is an assembly line, there is no time to come back to pick up Tao Ling from school, and his home is relatively close to the school, Tao Ling will go home by himself.

When I appeared downstairs at Tao Ling's house again, Liu Da was surprised: "Su San, why are you here again?" ”

I said, "I want to take a second look, there are some things I still haven't figured out, such as this pottery construction, yesterday afternoon's activities?" ”

Liu Da said: "This problem, you just call over, we have already investigated, Tao Jianshe yesterday afternoon the unit assembly line broke down, so the unit assembly line workers on a collective holiday, yesterday afternoon Tao Jianshe has been at home, but according to him, he did not go to the school to pick up Tao Ling." ”

As soon as I heard it, this is really a bit evil, Tao Jianjian's activities yesterday afternoon really have something inexplicable, he said that he himself stayed at home all afternoon, but who can testify? It seems that this trip still has to run.

I said, "Liu Da, I also want to take a look at Tao Jianjian." ”

Liu Da raised his eyebrows and said, "Oh, Tao Jianshe was taken a fancy by our Su forensic doctor?" ”

We went up to the second floor, and the policeman was still sitting there just now, Tao Ling didn't say a word, and it seemed that he still didn't take out anything useful.

I said, "Tao Jianjian, didn't you go to pick up Tao Ling yesterday afternoon?" ”

Tao Jianshe said: "No, I was resting yesterday afternoon, and when I got home, I lay on the bed and slept, and I didn't wake up until Tao Ling came home." ”

At this time, Tao Ling looked at his father, there seemed to be something different in his eyes, I seized this moment, I said to Tao Ling: "Tao Ling, when you came home yesterday, was your father sleeping?" ”

Tao Ling's eyes were a little flustered, and he didn't answer, and I had a doubt in my heart.

In fact, now I have begun to make assumptions in my heart, if what Tao Jianshe said is not the truth, he did go to school yesterday afternoon when Tao Ling was out of school, one possibility is that he received Tao Ling downstairs in the school, and he has no idea about the scene upstairs, and the other possibility is that he did not receive Tao Ling, so he went directly upstairs to find Tao Ling, and finally went directly to the teacher's office on the third floor, and also witnessed the scene, although this possibility is relatively small, but now the abnormal performance of their father and daughter makes me have to doubt.

I said, "Tao Jianjian, can we take a look at your shoes?" ”

Tao Jianshe said: "Yes. ”

So he took off his dirty leather shoes and handed them to Ling Fei, we got his shoes, and went out of the door, and began to inspect them at the door, Ling Fei was like the morning, and carried out a bloodstain test on the soles of Tao Jianjian's shoes, but there was no reaction at all, I shook my head in disappointment, there were more possibilities, but there was no blood on the soles of the shoes and Tao Jianshe could not rule out that Tao Jianshe had arrived at the scene.

The phone came from the laboratory, I picked it up, and sure enough, it was good news, the blood stains on the soles of Tao Ling's sneakers came from Teacher Ke Ying! Tao Ling must have entered the scene, not as she said, seeing Teacher Ke Ying's body at the door!

I immediately ran downstairs and told Liu Da the amazing news, Liu Da was also shocked when he heard it, he said: "This is a good situation, we will increase our efforts on this line, however, now the investigation has undergone some reversals, the proprietress of the supermarket in front said that the night before yesterday I saw Tao Jianshe arguing with a girl with glasses downstairs." ”

A girl with glasses? Teacher Ke Ying also wears glasses, so I asked, "Did the boss lady say the girl's height?" ”

Liu Da said: "Yes, as tall as Teacher Ke Ying, we showed her the photo of Teacher Ke Ying, she said that the street lights are not very bright, I didn't pay much attention, but the overall feeling is a bit similar." ”

Does Teacher Ke Ying have anything to do with Tao Jianjian? What is the intersection between a young female teacher who has just graduated from college and an uncle who has lost his wife in his forties? I was deep in thought.
