I observed the bullet holes in the deceased's face and the extent of the damage on the edges, and said, "Sister Du, boss, the pistol used by this murderer should be a Type 05 police 9mm revolver. ”

"Police pistols?" Xu Rui and Du Xiaoworm listened to me, and they both looked down at the same time, feeling that they were indeed similar.

The murderer actually held a police pistol, this revolver was officially approved for inclusion in police equipment in July 08, with high accuracy, low failure rate, good tactical and technical performance, but the power is relatively weak. There are also two types of bullets used, one is a special 9mm pistol bullet, and the other is a non-lethal 9mm rubber bullet.

The murderer was standing not close to the target at the time, and with the appearance of bullet holes in the deceased's face, it was bound to be a pistol bullet.

"Holding a police gun, not a rubber ......bullet equipped for daily tasks," Xu Rui touched his chin, and he whispered: "Xiaochen, Xiaoworm, you are here first, I will go to the Qu City Police Station, and ask them to check who lost the gun or who received this gun and ammunition in the gun store." I suspect that the time when the shot was lost was not close, or that the murderer was either within the police or had something to do with it. ”

"Boss, don't worry." I nodded.

"Mary's training is really good, and you can find the clues at a glance." Xu Rui patted his shoulder, turned around and returned to the car, and disappeared from our field of vision.

When I was in A0 before, Mary did teach me the characteristics of common guns and ammunition and the display of different things and flesh and blood, which is also one of the gun traces that are compulsory for trace experts, plus I personally tested it when I practiced with A0 combat power, and I had an indelible impression, so I can say that I have used it more or less except for particularly rare guns, but the most familiar one is a pistol.

Next, Du Xiaoworm and I interrogated the young men and women standing next to us, and learned the details of the identity of the deceased. The dead is named Wang Hai, who is a junior this year, and is about to enter his senior year for an internship. Tonight, he and his roommates and his roommate's girlfriends came out together to take a taxi to a distant restaurant to celebrate their birthday, but they didn't expect that Wang Hai was shot and killed when he moved to the tricycle on the side of the road just after leaving the school gate.

Not only that, Wang Hai and the two previous deceased, Kong Hui and Kong Jiating, had no intersection at all, which was very certain to his classmates, because they had never heard Wang Hai mention the other two deceased to anyone or had seen the two sides interact with each other.

This killing was too unforeseen, right?

I asked suspiciously, "Did Wang Hai offend anyone before his death?" Or what's the matter? ”

A young man said: "No, absolutely not, Wang Hai is quite small, how can he cause trouble?" And he studied very hard, and it was really not easy for us to shout him out once. ”

Du Xiaoworm's eyebrows furrowed slightly and asked, "Wang Hai usually stays in the school?" ”

"Yes, toilets, classrooms, dormitories, three points and one line." The other party said.

"Who has his parent's phone number?" I asked, glancing at the crowd.

Another boy said, "No, he has it on his phone." ”

I crouched down, put on my gloves and took out his phone, but there was a password, and I asked again, and no one knew it. It seems that you have to contact the school or use the system to find it along the vine.

"You write down your contact information and your name on a piece of paper, and you can go back." Du Xiaoworm said lightly.

"This ......" the boy was not happy, he said repulsively: "My brother has just had an accident, it's not good to let us leave, we want to spend time with him." ”

"Then I'll attend his funeral." I said without emotion: "Now no one can be sure whether the murderer is nearby, besides, if you go together, what if the murderer kills the wrong target and shoots it a second time?" ”

They hesitated, and then were dragged back to school by their respective girlfriends.

I looked at the murderer's side showing up to commit the crime three times, thinking about it and saying, "Sister Du, I found something, I don't know if you noticed it." ”

Du Xiaoworm said thoughtfully: "Is it about the murderer's grasp of the deceased?" ”

"Yes."

I guessed: "For example, Wang Hai usually doesn't come out, and it's rare to go out to dinner with friends today, but at this time, the murderer shot him directly." Besides, Kong Hui, she goes out to buy food for her roommate every day, and every day at dinner time, the school gate is overcrowded in this area, even if the murderer has been observing in advance for a long time, it is impossible to find Kong Hui in the crowd every day. Let's talk about Kong Jiating, the day after Kong Hui died, she bought food for her roommate, and she was also killed. In other words, the murderer grasped and determined the whereabouts of the deceased in advance before waiting for the rabbit. ”

"The murderer has eyeliner around the deceased?" Du Xiaoworm said suspiciously: "Or did the other party obtain information about the travel status of these deceased people by not attracting attention?" ”

"It's all possible, half and half probability." I thought for a moment, and then said worriedly: "Although the murderer's side has been in the same place for three consecutive days, the first day is a man, the second day is a woman, and the third day is simply a gun, so there will be a new form tomorrow, right?" ”

"It's not for sure, it seems that the pretender is ineffective before it can be used." Du Xiaoworm said helplessly.

I looked around and said, "What about the junior high school students who set off firecrackers?" ”

"When he saw the dead man, he found that the firecrackers he set off turned out to be the murderer's cover, so he was so frightened that he fell to the ground and convulsed on the spot." Du Xiaoworm explained: "I have been sent to the hospital by another police officer. ”

"How much did the murderer pay for it?" I said unexpectedly.

"Fifty bucks, approximately." Du Xiaoworm replied: "I found that he had a whole coin of fifty yuan and a change of more than ten yuan. Although he was shot in the face, because of the sound of firecrackers as a cover, and the deceased seemed to have turned his head to look around when he was shot, and was helped down by a friend before falling to the ground, his companions could not determine that the deceased was shot when he was facing that side, Lao Hei and Ye Jia could not judge the exact direction, and only speculated that it might be in the east or south, so they chased separately. ”

"This murderer is really good at picking the right time." I was puzzled and said, "Then the monitor should be able to see it." ”

Du Xiaoworm rolled his eyes and said: "After the incident, Lao Hei and Ye Jia rushed out, I was in the toilet, and when I came out, I didn't care about going back to the monitoring, so I went to the scene to control the situation, and when the police arrived, I went back and turned it over, Lao Hei chased in the right direction, so I contacted Ye Jia to go over there." ”

"Khan ...... Why do you say something that can be said at once? "I was depressed.

Du Xiaoworm smiled slightly and said, "I like to see you look anxious." ”

I awkwardly changed the subject and said, "They haven't been back for so long, have they found the gunman's traces?" ”

"It's not clear for the time being, I sent a message to Lao Hei, and he answered it and said um, and hung up." Du Xiaoworm said.

At this moment, I noticed two figures appearing in the south, namely Lao Hei and Ye Jia, both of whom looked empty-handed and did not catch the gunman.

After a short time, Lao Hei and Ye Jia came close to us, and I noticed that Lao Hei's body was dirty, the clothes on his arms were torn, and the back of his hands was also torn, but Ye Jia was intact.

I was surprised and said, "Brother Hei, how did you get this?" ”

Lao Hei smiled bitterly and said, "Don't mention it." I ran out less than 100 meters and found a particularly suspicious man, because his pocket vaguely had a gun-shaped outline, I was about to go up and interrogate, the other party saw my posture and immediately ran away, he also grabbed a student's bicycle, and then I also requisitioned one, chased out for almost a few kilometers, and was about to catch the other party, an unlicensed van rushed over, lost my speed, and suffered a little skin trauma. ”

"An unlicensed van halfway through?" I tightened my eyebrows and said, "This is the murderer's accomplice." ”

Lao Hei nodded and said, "After this delay, the van driver and the bicycle are gone." Then I saw the leaves as I walked back, and I came back in pieces. ”

Ye Jia spread his hands and said: "It's really not easy for me to find the past, and I have inquired about many stores in a row. ”

Du Xiaoworm asked: "By the way, Lao Hei, have you seen the gunman's face?" ”
