Police order

Chapter 111 Fishing Line?

The Criminal Investigation Brigade of the County Bureau arrived soon, and many "contestants" who participated in the selection also arrived one after another. The professional team led by the tour team quickly started to work, and none of the local police stations followed.

Who wants to go up?A human head is placed there!

The corridors and corridors were inspected, but no valuable clues were found, and this place was mowed again this morning.

Every morning, the waiter would mop the stairs and aisles, because Jin Linglong reported the crime after ten o'clock in the morning, so the outdoor clues were of little use.

"Each type of site has its own characteristics. The main energy of a hotel site is indoors. Outdoor inspections are too messy, and a hair may be picked up, which was left by a guest last month." You Shaohua and Lu Ling said.

"I feel more at ease when you come." Lu Ling nodded.

He, Lu Ling, is indeed good at psychology, but as a new policeman, if such a scene is completely entrusted to him, he doesn't know what to do. If You Shaohua doesn't come, the initial development will be difficult.

All the personnel on the first floor were kept in four rooms on the first floor in batches, two for women and two for men, and each room was equipped with three policemen or auxiliary policemen.There are quite a few assessors, and the criminal police brigade has three more cars, so the manpower is very rich now.

With all these people locked in the house, it is much easier to discuss the case now.

Team Huang also came. He was one of the chief examiners of the county bureau's assessment. He arranged for all personnel to come up in batches to observe the on-site investigation on the third floor.

In addition to You Shaohua, Lu Ling, and Qingshan, there are 4 policemen and 10 auxiliary policemen who signed up for the selection. More than half of these people have never dealt with a murder scene. Seeing such a scene, at least 10 people emo on the spot. A few people just looked stupid.

Selecting a professional police officer from the police force is in itself the same thing as selecting a "special soldier". This kind of scene requires a lot of experience.A soldier should not be afraid of blood, and neither should the police.

You Shaohua knew that for today's trip, at least three or four of the other 14 applicants would quit.This is very realistic. Most people do things with passion, which can be extinguished with just a pot of cold water.

Except for the two policemen from the county police station, the others have basically lost their combat effectiveness, so they can only guard the people here on the first floor.In the police stations in the counties, there are more contacts with abnormal deaths (suicides, car accidents, etc.), and the resistance is still a little higher.

Lu Ling endured the discomfort and studied the case near the door of the house. The guerrillas didn't go in, but just directed outside.The guerrillas are not experts in on-site investigations, let alone forensics, so it is not very useful to go in.

"You team, there are many traces of people coming and going in this room, and there are many footprints, but it is strange that they are all the same footprints." Police officer Lan, who was in charge of the survey, was a little puzzled: "It feels like the suspect is deliberately confusing us. .”

"Probably not," Lu Ling said, "their hotel has uniform slippers, which are a bit big, size 42-44. As long as you wear slippers, the footprints will definitely be the same."

Theoretically speaking, different feet wearing the same slippers will have different footprints, but this hotel is hardened, and this difference is difficult to see.

"It's a little troublesome," Officer Lan frowned.This case is a natural disadvantage, which directly cuts off a skill of the current survey police.

As the investigation progressed, another very bad news came from inside.

The windows are also closed, and the inside is a little locked.

This kind of window is made of aluminum alloy. There are two opening and closing methods. One is to turn the window handle to the top, so that a gap of about five centimeters can be opened from the top for ventilation; the other is to turn the handle to the right. , so that the entire window can be opened.If the handle is turned down, the window is locked. (see the comment area for the picture)
At present, the window handle is partially locked down, and the window is already locked and cannot be opened from the outside, but it is not locked. (see the comment area for the picture)
Officer Lan looked at the falling snow outside the window, then tried the window carefully, and found that it was indeed locked.Even if it is not locked, it is locked.

In other words, it is almost impossible for the murderer to run out of the window, because there is no way to close the window after going out.

The windows in the Northeast are very tight and airtight.

The house has been thoroughly screened, there is nowhere to hide, and there are no other means of access, only doors and windows.

If it is not through the window, then it must be the door, but how can this kind of door be bolted after going out?

"The handle of the window is down. Is it possible that a fishing line was tied outside, pulled down, and then pulled down a little to lock the window, and the fishing line fell off?" You Shaohua asked.

"This possibility is not ruled out. I haven't opened the window to see the traces yet," Officer Lan said. Experts come over and consider whether to open the window or not. However, the airtightness of this window is really good, if it is fishing line, it is not impossible to pass through, but the part where the fishing line is tied and knotted will be more difficult.”

"Maybe there is a special way to tie the knot, and it will be untied after pulling it off." You Shaohua said.

"Well, this is a way of thinking about the problem." Officer Lan did not refute: "The on-site preservation of this door is still good. It was directly pried open from the door leaf on one side, and the latch has not been moved. This door According to what you said, it is also possible to hang the latch on one side of the door first, and then pull it out with a fishing line. We don’t care about this right now, we have to do experiments to see if it’s feasible.”

"Okay", You Shaohua did not continue to discuss this issue.

If it is fishing line or iron wire, it will face ultra-detailed investigations such as trace physical evidence detection, which is a technology unique to the Municipal Bureau.

Whether it is fishing line or iron wire, after the doors and windows are closed, there will be great resistance to passing through anywhere, and it will definitely cause wear and tear.On the one hand, it is the wear and tear of the fishing line and iron wire itself, and on the other hand, it is the wear and tear on the places where the doors and windows pass through the fishing line and iron wire. These cannot escape the trace physical evidence test.

"Your team, the body was killed by someone attacking the heart with a knife. The width of the knife in the heart was more than 5 cm. The knife was very sharp. It may be a machete, and it should not be small. The head was chopped off after the death. There is a high probability that it is a knife." Forensic doctor Zhang reported and thought for a while: "If it is really a knife as I said, this knife needs to be slender and have a certain ability to chop bones."

There was no knife at the scene, indicating that the murderer took the knife away.Such a large knife is very difficult to carry. If this is an ordinary machete, then the murderer must have a special reason for taking it away.

Judging from the current situation, except for Cui Bi and Xiang Yujiao who came from Beijing with big suitcases, everyone else has backpacks, so it is very difficult to bring such a machete.

Also, if fingerprints and such are wiped off, wouldn't it be good to leave it on site?After taking it away, where do you hide it?
