Xiao Li and Shen Qingyan first went around the trash can, this alley had been cordoned off, and there were still people there when Shen Qingyan and the two went.

After Shen Qingyan and Xiao Li showed the person the documents, the man let them in, Shen Qingyan looked around the trash can, walked over and asked the staff, "Did you find anything?" ”

The staff looked up and sighed, "There are always people coming and going in the garbage cans here, and garbage is constantly thrown into it, and it is impossible to leave footprints on this kind of road except for dust, so nothing has been found yet." ”

Shen Qingyan nodded, "It's hard work." ”

Then Shen Qingyan walked back to Xiao Li's side and shook his head silently, Xiao Li also sighed, "This is also normal, handling cases is always like this." ”

Shen Qingyan looked at the alley, "I'll take a look." ”

Xiao Li nodded, "Okay, you first watch me go to the nearby residents and record a confession." ”

"Okay."

After the two separated, Shen Qingyan walked around the alley, this box was relatively narrow as a whole, and judging from the blood-stained nurse's uniform, there must have been some conflicts between individuals.

Although it is not known where the fight took place, it is possible that the girl made some noise or attracted some attention during the fight between the two of them.

Obviously, these situations may attract other people, so the criminal hurriedly dropped the nurse's uniform here and took the girl away, if it was in the house, it was not easy to cause a noise, so the struggle between the two people was likely to take place in this alley, so the criminal was forced to leave the nurse's uniform in this obvious place.

Suddenly, some traces on the wall caught Shen Qingyan's attention, the wall here had also been in disrepair for many years, and it had become a little fragile.

There are some very new scratches on it, and the wall has been rubbed off, and the situation inside the wall must have happened not long ago.

There is a footprint in the corner of the wall, half of that footprint is stepping on the stone, and the other half is in the dust, but this footprint is somewhat familiar, Shen Qingyan took a photo of the footprint, this footprint seems to be the same as the one on the back mountain that day. There are some similarities in the pattern of the footprints.

However, the back mountain is more vague, so Shen Qingyan is not sure if it is the same, Shen Qingyan sent the picture to the personnel of the technical department, "Help me compare this footprint with the footprint in the back mountain to see if there is any similarity." ”

The people in the technical department moved quickly, and the comparison results came out quickly, and these two footprints should have been left by the same person.

This is a major discovery, and if there is this discovery, the two cases should be able to be investigated together.

Shen Qingyan searched in the alley, and finally saw something that seemed to glow in an inconspicuous corner of the wall.

Shen Qingyan walked over and took a look, it was a ring, this ring looked quite new, it should have been bought recently. First Literary Network

Shen Qingyan put the ring in the evidence bag and prepared to investigate it carefully later.

In the end, Shen Qingyan went to the homes of nearby residents, if the thoughts that happened in the alley were to be heard first, it must be someone close to the alley, so Shen Qingyan went to ask.

The family generally went to bed early, there was an old lady at home, and everyone else went to work, Shen Qingyan looked at the old lady, "Have you heard any special sounds in the past few nights?" ”

The old lady thought for a while, "The night before yesterday, we both slept, but my sleep has always been relatively light, and in the middle of the night, the dog barked for some reason, and barked very fiercely, and I woke up." ”

"After that, I wanted to go out and have a look, but when I got to the door, I heard a woman's scream, and then I opened the door, and I saw a man pulling a woman out of the alley, maybe a little couple quarreled, I didn't care, and then after the man left, the dog stopped barking, and I went back to sleep."

Shen Qingyan thought for a while, "Did you see what kind of clothes that woman was wearing?" ”

The old lady frowned, "Oh, it should be the man's coat he was wearing, I think the man is wearing only a shirt." ”

Shen Qingyan recorded what the old lady said, if it looked like this, what the old lady saw that night was probably the criminal and the nurse.

At that time, the nurse should not have died, the criminal and the nurse had a fight, and the criminal injured the nurse and attracted the attention of the dog, the dog's sense of smell is more sensitive than that of a human, probably the breath of blood stimulated it, so it began to bark.

The criminal was worried that the barking of the dog would attract the attention of the residents who lived here, and with the nurse, who was already stained with blood, let go out would also attract the attention of others, so he left the nurse's uniform there and left with the nurse.

This is the most reasonable guess at present, after Shen Qingyan and Xiao Li finished investigating, they returned to the police station together.

After going back, everyone was still busy, Shen Qingyan went to Zhang Haonan to report, and told Zhang Haonan about his discovery and the idea of hoping for a joint investigation, Zhang Haonan looked at Shen Qingyan, "The upper authorities have approved our joint investigation, and the impact of these two cases is very bad, so we must solve the case as soon as possible." ”

"And the two cases happened less than a week apart, and the criminal's actions are more frequent, so we must catch this criminal as soon as possible to avoid the appearance of the next victim."

"The fate of this victim is still uncertain, and I hope that all of you can hurry up and solve the case as soon as possible."

"Yes."

After finishing speaking, Shen Qingyan took out the ring from his bag and put it on Zhang Haonan's table, Zhang Haonan looked at Shen Qingyan, "This is?" ”

Shen Qingyan said in a deep voice, "This is what I found at the scene of the crime, most of the residents living there don't have the strength to afford this ring, and ordinary people wouldn't be careless enough to throw the ring in that kind of place." ”

"The place where the ring was found was very close to the place where I found the footprints, and I guess the nurse dropped the ring in a hurry, or maybe she deliberately left the ring there in the hope of attracting attention."

"Before I came back, I went to investigate the nurse's account flow during this time, and there was no large expenditure, so it is very likely that the ring was bought by the criminal for the nurse, and the nurse hopes to leave this ring for the police to leave clues, and find out the criminal to save her life, but this is my current guess, I don't know if it is accurate."
