Back in the game, Xu Xiaodong leaned on the seat and was applying eye drops. Seeing the two of them came back, he said, "Did the murderer catch it?"
"Do you think it's so fast?" Lin Dongxue said.
"I don't have to look at it if I get it... I almost didn't look blind one day."
Chen Shi said, "Are you at 1x speed?"
"Yeah, don't you tell me to look carefully?"
"Too honest, right? 2x speed is enough!"
"Go, don't say it soon! No, my eyes are uncomfortable. Go to the window and stand for a while."
Chen Shi sat down and asked, "Who has entered the duty room?"
"There is no one, only the security guard himself."
"Sure?"
"I'm pretty sure, didn't it mean that the murderer entered the duty room and deleted the record? I stared at it for a day, and no outsider has ever entered the duty room!"
"Then who do you think deleted the record?"
"Uh... I heard that there is a kind of optical camouflage that can make people invisible..." Xu Xiaodong began to wander around again.
Chen Shi smiled and shook his head, and said: "Let me ask something more reliable, what do you think Dongxue?"
Lin Dongxue said: "If only the security guard himself enters the duty room, then eliminate all the impossible, and the rest is... But this is also impossible. Why does the security need to delete the record by himself? But it is on the knot of the death case."
"The community is usually very peaceful. No one is going to watch the surveillance. The security guards work day after day, basically facing the computer all day. Suddenly one day there was a homicide here. He actually formatted the hard drive. What is the reason?"
"There is something invisible in the computer?" Lin Dongxue said.
Xu Xiaodong exclaimed, "I understand. The security guard usually downloads too many A-films, so he formatted the hard drive for fear of being discovered by the police and expelled by the boss."
Chen Shi thought for a while, "Although your thoughts are trivial, one thing is on the point. The security guard is most afraid of not being able to detect the murder, but being expelled, so he doesn't care about the murder, as long as the contents of the hard drive Don't be seen and just OK!"
Chen Shi opened the folder, "Hey, why is there only one video in this USB flash drive? Nothing else?"
"When the Information Division handed it over to me, there was only video."
"Hurry up and stop one or two, let them restore the entire hard drive, I want to watch everything."
The three of them unkindly stopped a young brother who was late from get off work, and forced him to work overtime as a bait for dinner. At this time, Peng Sijue passed by and Chen Shi called him: "Old Peng, is the second autopsy done? "
"It has been dissected, but the ballistics expert has already left work, so the report has not been written yet."
"Anything to find?"
"Come and take a look."
Chen Shi followed him to the forensic laboratory. Two forensic doctors were working. The corpse was opened. The forensic doctor was taking out the bone fragments piece by piece. There were dozens of fine bone pieces on the plate next to it.
Peng Sijue said: "I was just going to find you. I found a suspicious point when dissecting the corpse. You know that a bullet entering the body will quickly open a nearly vacuum cavity in the body, and then air will pour in from behind, causing a second explosion. So There will be a lot of broken bones around the bullet exit."
"Just say the conclusion."
"You previously judged that the back is the entry port, but the front chest does not have too many broken bones. Instead, the back is broken more, and the blasting direction is backward. It seems that the front chest is the possibility of entry. Higher sex... I have kept the clothes of the deceased, and I will check with a ballistics expert tomorrow."
"Shot in the chest!?" Chen Shi was a little surprised, and took Peng Sijue to the outside, looking for a pen to point him.
Peng Sijue said: "What are you doing!"
"Restore the scene!"
"Wait..." Peng Sijue took out a box of plasticine from the drawer. "Use this. We bought it for a non-Newtonian fluid experiment."
When Chen Shishi put plasticine of different colors on the table, he said: "This is the bridge, this is the river. People are standing here to pee. If the front chest is the entrance of the bullet, where will the murderer be? In the river? "
"Who told you that the deceased was urinating?"
"As the security said, they would go to the river to urinate at night."
Peng Sijue turned the plasticine that marked the villain, "Maybe the deceased felt that there was someone behind him, turned it around, and was shot into the water... No way, this kind of trajectory cannot be shot, the trajectory will be high and low."
"The murderer shot in the water?" Chen Shi suddenly, "the murderer shot in the water! I understand, why the murderer was not photographed by surveillance, that river! Walk around!"
"Where to go?"
"Site! You bring a protective suit, the kind that is waterproof."
The two drove back to the scene. At this time, night had fallen, and the community was full of lights, peace and tranquility. Chen Shi came to the scene where the security guard was killed. Peng Sijue already knew his intentions and said, "Are you sure you want to do this at night?"
"The incident was also at night, so it was restored."
"I won't go down."
"Watch the wind here!"
Chen Shi put on the protective clothing and immediately felt sultry and difficult to handle. After entering the water, he felt a little more comfortable, but the water was mixed with domestic sewage from the residents, and it stinks. He asked for a flashlight from Peng Sijue and walked under the bridge with the light on.
This bridge is actually half a road bridge. There is water on one side and no water on the other. In fact, there is a pipe underneath. He walked forward with water dripping from his waist. The wall of the pipe was covered with disgusting moss and it was very stuffy. The protective clothing was already full of sweat.
I don't know how far I have gone, a light appeared in front of him, and Chen Shi climbed up and got out of an inconspicuous ditch in the community.
He was overjoyed. This was the secret of the murderer's disappearance from the surveillance. He almost raised his hand to cheer. At this time, a resident found him, thinking it was a suspicious person, and screamed and ran away.
Chen Shi ran out of the community. Peng Sijue was still holding his hands and looking into the water. He said, "I know, I know. The murderer came out of the waterway. The peeing security guard saw a person emerge from the water. The murderer killed him."
"What about the disappearing surveillance?"
"That's a coincidence... I took off my clothes first."
Smelling his body, Peng Sijue frowned, "Why don't you get a small paper boat to test?"
"It's easy to say, the entrance is not so found. It is hidden in a green belt in the community. It may be a rain well, but there is no cover on it... The killer either knew about this exit before or stepped on it beforehand."
"In this way, she is quite smart!"
"Do you want to go in and explore, see if there are any clues?"
"What do you think?"
Chen Shi thought for a while and said, "Forget it, the inside is very dirty, it's all sewage, there should be no evidence of it."
At this time, Lin Dongxue called and said, "Where did you go, chasing Captain Peng out, why did you disappear?"
"I and Lao Peng are at the scene."
"I slipped away without saying hello, really!" Lin Dongxue smiled bitterly.
"Did you find anything?"
"I found it, um... It's hard to say in one word, I'll send you a few to feel it!"
