Just after 12 midnight, I woke up from my sleep with a call from Brother Ming, saying that a murder had occurred in the "Milian" hotel in the city center. I hung up the phone extremely tiredly, yawned and walked downstairs. It's not that I'm slacking off mentally, it's just that these murders happened one after another, which made me obviously feel severely exhausted. You must know that it has only been three days since the last murder.
But when I heard that the murder happened in a hotel, I finally felt relieved. Many people don¡¯t know that the geographical location where certain cases occur plays a crucial role in the investigation and solving of cases. Take a hotel as an example. As long as it is operating normally, according to special industry management regulations, there must be a large number of cameras installed inside the hotel, and now all hotel accommodations require real-name registration. Judging from these two points alone, there is almost a clue to the detection of the case.
The survey vehicle driven by Fat Lei arrived as scheduled, and 15 minutes later, we arrived at the outskirts of the hotel.
"Director Leng."
"Team Xu, what's going on?"
"The murder occurred in Room 406 of the hotel. The first person found was the floor attendant, and later the front desk attendant called the police. The deceased was a man, about 50 years old, who was killed in the bathroom. The hotel's accommodation system showed that that night The person who checked in was a girl named Zhang Wen, and I have asked someone to track down this person."
"Do you know the condition of the deceased?"
¡°It¡¯s not clear yet, the front desk has only registered one person¡¯s information.¡±
"Okay, let's go up and inspect the scene first."
Fortunately, the case occurred in the early morning, otherwise it would definitely cause panic. After all, this is a downtown area. However, the more this happens, the tighter the time left for us. In order to eliminate the impact in time, we must complete the first site survey before dawn. Before I walked into the elevator, I glanced at the wall clock in the lobby. It was 1:30 Beijing time; that is to say, we had less than 6 hours left.
As the elevator went up, Pang Lei glanced at the camera at the corner of the elevator, and his expression became slightly more relaxed. But when we walked into the fourth-floor corridor, the scene in front of us completely stunned us. Except for the bright pink light emitted by the room's door number light, the entire corridor is almost invisible. In other words, the floor surveillance is just a decoration.
¡°I¡¯ll beat your lungs out.¡± Fat Lei cursed in annoyance.
We walked out of the elevator, turned right, and walked to the middle where we finally found room 406. When I pushed open the wooden door, my heart froze again. No matter whether it was indoors or outdoors, the floors of the hotel were all covered with thick carpets. This kind of floor could not leave any footprints at all, because the gaps in the carpets were serious about hiding dust, even if they were used Electrostatic adsorption instruments are basically ineffective.
¡°Just go in.¡± Brother Ming said to A Le and me.
Although Brother Ming is a forensic doctor, as the head of the technical room, he knows what kind of investigation methods are needed for any scene. Sometimes he already understands without my explanation at all.
After simply handling the door, I entered the house. It was a large bed room facing north and south. The house was very large, about 50 square meters. The door was a brown wooden door that opened to the south. On the right side of the door was a room for use. The bathroom is separated by glass. Going further inside, there is a large pink bed of 2 meters by 2.5 meters against the west wall. There is a row of wardrobes embedded in the wall against the west wall of the room. In addition to the decoration of the room, Except for the alternative, the rest are not much different from ordinary hotels. If I had to point out one thing or two, the most eye-catching one should be the "joy chair" in the room. It is not convenient to go into details about the functions of the chair.
Simply glanced at the room, except for the messy men's clothing on the chair, other places were relatively neat. Because the hotel itself does not have too much furniture, trace processing saves a lot of time.
"Brother Lei, let's go to the bathroom." I picked up the investigation box and stood in front of the open glass door. In fact, this was the focus of my investigation. Why do you say that? Because people come and go in the hotel frequently, it is easy for cross-infection of trace evidence, such as the door handle, which has been touched by many people from the time the report was reported to when we arrived at the scene. The suspect's fingerprints are likely to have been destroyed. The same is true for other furniture and furnishings. I couldn't tell how many residents had left their fingerprints on it, which made the investigation very difficult. But things are different at the central scene. When the crime occurs, there are only the victim and the suspect, and it is very likely that crucial physical evidence information will be left behind.
The surface of the glass is smooth, and it is not that troublesome to handle. I quickly revealed clear fingerprints. Pang Lei was responsible for taking photos, and A Le was responsible for recording the specific locations of trace evidence.??After they both finished their work, I opened the glass door of the bathroom.
The layout of the bathroom is not as elaborate as the room. Near the southeast corner is a shower head that still leaks water. In the northeast corner is a Toto (Eastern Pottery) toilet. To the left of the door is a marble sink. In addition, there are no other unnecessary furnishings in the nearly 8-square-meter bathroom.
The body was lying on its back on the tiles with its head east to west, probably because of the shower, so there wasn't much blood on the body and the ground. A golden machete about 20 centimeters long was thrown at the drain. It was visually estimated that the cause of death was a sharp injury to the heart.
"The water on the ground is too serious, and the possibility of leaving footprints is very small." I frowned and said.
"If not, I'll call Director Leng and the others to come over and inspect the body directly?" A Le interjected.
"Don't worry, I'll take another look." As I said that, I took out the multi-band light source from the survey box, adjusted the light to the strongest setting, and checked the ground again. The reason why I did this was mainly because of one of my guess. I had been pondering this speculation since I entered the room.
Let¡¯s analyze it from the beginning. The deceased was killed naked in the bathroom. Judging from the fact that there was still a little foam on the body, he was probably killed while taking a bath. In such an ambiguous room, the victim was naked again. , so I have reason to suspect that the suspect is more likely to be a woman. Unless the sexual orientation of the deceased was abnormal, two grown men would not choose to stay in such a themed hotel. After all, there are many large and small business hotels in Yunxi City, and this is one of them.
Secondly, I found that two pairs of disposable slippers in the room had just been taken apart. One pair was worn into the bathroom by the deceased, and the other pair was thrown in the trash can. From this, it is not difficult to judge that the suspect is likely to be one person, a man and a woman, who came to check out the room. This is also consistent with most situations.
Third, I found a suspicious point on this pair of discarded disposable slippers.
The deceased was taking a shower when he was killed. If the suspect entered the room wearing slippers to commit the crime, the disposable slippers would inevitably get wet from the splashing water, but I did not find any signs of water immersion on these slippers. That is to say The suspect was most likely barefoot when he committed the crime.
We all know that the soles of human feet, like the palms of the hands, have lines, and the main component of foot prints is grease. If the suspect really walked barefoot on the bathroom tile floor, he would most likely leave clear barefoot footprints. Grease is insoluble in water, and water stains on the ground will not damage it. This is just because the grease is relatively transparent, and coupled with the water stains, it is difficult to create contrast and is difficult to detect during the inspection process.
In order to confirm this guess, I decided to conduct another survey after the water damage on the ground completely receded. (Remember the website address: www.hlnovel.com
