As the saying goes, if the murderer is not stupid, he can guess that the police will be on guard at the scene, so if the other party dares to come to the third bullet, he will either die or be absolutely sure. We don't know anything about the murderer at the moment, and no one can figure out what the other party thinks in their hearts, and we feel that it is necessary to place a camera, so Xu Rui let Lao Hei and Du Xiaoworm go together. Because the night is very dark tonight, there has been an accident for two days in a row, and there is no stall at night, it looks extremely deserted, and the old black complexion has the advantage, and he will place it, and the murderer may not be able to detect it if he peeps nearby.

After a gap of twenty minutes, Du Xiaoworm and Lao Hei returned, and they said that they had placed cameras diagonally above all the places outside the east gate that could gather people, and they were all using pretenders.

Du Xiaoworm took out her laptop, she turned on the system and entered the number to load, and a real-time synchronization scene appeared on the screen.

At this time, the Qushi police had already been dispatched, divided into several groups to search here, tossing for most of the night, and did not find any suspicious people, perhaps the movement was too big to alarm the other party.

When we got up the next day, we went to the Qu City Police Station, where Kong Jiating's parents had been after the accident last night. Du Xiaoworm took off the murder weapon, observed it for a while, stitched up the wound, and asked the deceased's parents to bring the body back.

The fruit knife used by the murderer this time is relatively new, and it should have been bought just before the move.

We thought about it for a moment and thought we could start with this murder weapon. So we returned to Xiguan Street and checked all the shops that might sell this kind of knife, there were three, two of them had surveillance inside, and the other one had a sign on the door that said, "There is surveillance inside, and a fine of 10 will be imposed for stealing." ”

But it's just for show.

We interrogated the first two, and the boss said that the fruit knife was not sold yesterday or the day before yesterday, not only that, but it had not been sold in the past half a month, and a few vendors had come to buy it half a month ago. The tone was very affirmative. The male murderer used a fruit knife to steal Kong Jiangyuan in the evening before yesterday, and the female murderer should have bought this knife after the first case the next day.

Lao Hei was in charge of going through the surveillance, and what this boss said was indeed the truth.

We went to another one with surveillance, where the price of the same fruit knife is two yuan cheaper than the first one, so the sales volume is not a scrappy, and it looks like a few can be sold a week, some of which are bought by students to cut watermelons, and some are used by vendors or people from restaurants.

After Kong Hui's accident the day before yesterday, only one fruit knife has been sold in this store.

We flipped through the surveillance and found that the buyer was Kong Jiangyuan, who bought it yesterday morning.

We left the shop and were talking outside.

Xu Rui touched the bottom and said: "When the crime happened yesterday, Kong Jiangyuan was in front of his stall, and we saw it with our own eyes, but this does not mean that he has no possibility of helping the murderer buy a murder weapon." He didn't go out with his wife today, Lao Hei, you can run to Kong Jiangyuan's house. ”

"Okay." Lao Hei took Xu Rui's car keys and went to the destination alone.

Then Ye Jia, Xu Rui, and Du Xiaoworm and I went to the third shop that sold this kind of fruit knife, and it is worth mentioning that the boss actually said that yesterday afternoon, about four o'clock and five o'clock, there was a woman with long hair, she carried a bag with watermelon, and came to him to buy this fruit knife.

Long-haired woman!?

I was shocked and asked urgently, "What does that woman look like?" Are there any characteristics? ”

The third boss thought about it for a while, and said with a vague impression: "At that time, my wife was next to me, and I didn't dare to stare at people's faces, but I glanced at it, and there were some red and purple acne scars on this woman's face, and the area was not small." The facial features are quite standard, if it weren't for the impact of those acne scars, it would be absolutely beautiful. ”

"Is there anything else you want to add?" Du Xiaoworm asked.

"I'm going to think about it......" The boss thought for a moment and said, "It seems that she has a cross-bag in her other hand." ”

Nine times out of ten, this is the woman who opened up with the deceased when the second case occurred.

I said solemnly, "What color?" ”

"One side is black." The boss replied, "Although there is a large part of the other side against her body, it should be white from the side." ”

The four of us stared wide-eyed, no wonder some said that the white was black, and some said that the bag was white! The colors on both sides of the bag of the suspicious person are different, and the angles of the witnesses are different, and the colors they see are naturally different.

We left the third store and looked around, the sky eye in Qushi is not as dense as Qingshi, but at least the intersection is monitored. They got into Du Xiaoworm's car one after another, went to the road monitoring center in Qushi, and inquired about the image of the time period when the boss said that the woman bought a fruit knife yesterday.

After half an hour, the monitor pointed to the paused screen and said, "Are you talking about her?" ”

We leaned in front of the screen to observe, and the woman in the video was carrying a cross-bag, one side facing black outward, her hair was long, but the other hand was not carrying a watermelon, and she was thrown into the trash after leaving the store. Then the woman disappeared into the surveillance footage and squeezed into the crowd.

Xu Rui thought for a moment, and said the time of the crime yesterday evening, and he commanded: "According to this time, turn over the monitoring of all the intersections near Xiguan Street, in order to save time, let all the monitors work together, each camera will be turned for at least three hours, and the multiple of fast forward should not be too large, otherwise the other party will be on this side of the field of vision in the last second, and the next second will leave the field of vision to that side, which is the same as not turning over." ”

"Okay." The monitor nodded.

"There is also a task, to finish yesterday's translation, and then to the same time the day before yesterday, the target is a man with an inch head, the clothing is unknown, the height is unknown, and the bag he is carrying is the same as the woman's style, the color may be black, or it may be white, but anyone who meets this condition is marked." Xu Rui took out a piece of paper on which he wrote, and he said admonishingly: "Let's go first, and send the results to my mailbox after we are done." ”

We left the road monitoring center, and now Lao Hei has also left Kong Jiangyuan's house, and he called to say that the other party bought a fruit knife because he lost it the day before, purely to replenish the knife. We think it's reasonable that this case has nothing to do with the other party.

We returned to the hotel, rested for a quarter of an hour, and prepared to go to the next Qushi University to find Kong Hui and Kong Jia's other roommates to find out the situation. However, when I arrived at the girls' dormitory building, I heard from the administrator that the two girls were so frightened that they contacted their parents and were taken home this morning.

Not only that, but the case that appeared for two consecutive days has already bred panic in the hearts of Qu Normal University, especially the girls living on campus, and groups of boys spontaneously organized to deliver meals to girls every day.

Our A7 was divided into two groups again, Du Xiaoworm and Lao Hei and Xu Rui went to the house of the deceased's roommate Wang Yu, and Ye Jia and I went to the house of another roommate named Huang Juan, planning to rush back to Xiguan Street before this evening, worried about another murder.

Ye Jia and I drove Xu Rui's car and spent 40 minutes to Xiaoji City, where Huang Juan's house is located in the Canal District. We inquired a few people, and finally arrived at the destination, parked the car and came to the door of 1 single 302 households in Building 1.

I didn't knock on the door and called Huang Juan's mobile phone number.

After a few seconds, Huang Juan's father opened the door, he put two pairs of slippers on the ground and said, "Police officers, please come in." ”

After we changed our shoes, we sat on the side of the sofa, Huang Juan and her parents were on the other side, and I asked, "Huang Juan, why did you and Wang Yu go home?" ”

"The Campus Forum has ...... There was a post ...... "Huang Juan's voice trembled, and it seemed that she was really frightened."

"Posts?"

I tightened my eyebrows and said, "What's in there?" ”

Huang Juan curled up beside her mother, like a frightened fawn, and said, "Xu...... Officer Xu, open it and look at it yourself...... bar. ”

I took out my phone and easily found the campus forum of Qushi University, "Which section?" ”

"Gossip in the rivers and lakes." Huang Juan said.

I clicked on what she said, and I and Ye Jia saw a post that was pushed high at a glance, at least thousands of replies, and there will be new replies or likes every few minutes, the landlord's ID is "I won't die", but the title of the post makes us feel a chill down our spines......
