Every homicide has a certain cause, and different methods can be used to achieve the crime scene seen by the police.
The same murder case and the same crime scene need to be interpreted in different ways in different living environments.
For example, in a small city like Meihai City that has not yet been fully developed, Lu Wan knows that cases in big cities cannot be used as a reference. Between impromptu murder and planned murder, Lu Wan will choose the former.
The reason is simple. Many of the small streets outside Tongzi Tower are dimly lit and there are few pedestrians. It is safest to kill people there.
But there are still some things that Lu Wan cannot explain, or in other words, there are some thoughts that Lu Wan does not want to admit for the time being.
In the room where the crime occurred, Bai Mo walked into the master bedroom and scanned the room with his eyes.
The master bedroom was relatively large. Bai Mo's eyes fell on the table beside the bed, where there was a photo frame with a photo of a man and a woman.
When he came to the table, Bai Mo picked up the photo and looked at it carefully.
The man in the photo looks average, and the woman looks pretty good, with an oval face and a particularly beautiful nose. If a woman has long hair, she is most likely to die in the bathroom.
"Don't move things around. What if the evidence is contaminated?" A woman's voice came into Bai Mo's ears.
Bai Mo looked back and saw that it was Chen Xiaoxiao, a colleague from the police force. She was looking at him with a dissatisfied look.
Bai Mo knew that Chen Xiaoxiao was a newcomer to the police force. When Lu Wan introduced her yesterday, Bai Mo noticed that Chen Xiaoxiao's attitude towards him was abnormal.
You know, Bai Mo is already a well-known painter abroad. His ability to capture the details of pictures is far better than ordinary people, especially human faces!
When having dinner with Bai Yonghui last night, Bai Mo learned about the recruitment process of the police force and was basically sure that Chen Xiaoxiao was angry with him for entering the police force because of his connections.
However, Bai Yonghui spoke highly of Chen Xiaoxiao, saying that she was a talented student who graduated from a prestigious university with strong professional ability and would definitely achieve results in the future.
"I'm wearing gloves." Bai Mo explained with a smile. His smile was always sunny, but this time it didn't seem to affect Chen Xiaoxiao.
Putting down the photo, Bai Mo walked to the closet again.
The closet was open and a lot of clothes were scattered on the floor.
Bai Mo easily saw the arrangement of the deceased's clothes. He first looked at the grid where the deceased's socks were placed, then looked at the grid where the deceased's underwear was placed, and finally roughly went through the deceased's clothes.
The whole process took nearly fifteen minutes. Chen Xiaoxiao, who had been staring at Bai Mo, gradually became surprised. She could tell what Bai Mo was looking for.
A thought flashed through Chen Xiaoxiao's mind - does he know how to investigate cases?
At this time, Lu Wan's voice sounded in the living room, "What did you find?"
Bai Mo and Chen Xiaoxiao looked out the door at the same time, and then came to the living room.
The policeman who collected evidence at the door said: "The door lock showed no signs of damage, the inner door handle had been cleaned, and no fingerprints could be extracted."
Lu Wan nodded. This was the same as she had judged when she first came in. She looked at Qin Youwei who came out of the bathroom.
Qin Youwei took off his mask and gloves and said slowly: "The time of death should be between one and two o'clock in the morning. The cause of death was mechanical asphyxia. The murder weapon should be the towel next to the toilet. The deceased had multiple soft tissue contusions on his body. , there are many bruises on the chest and abdomen, all caused during his lifetime."
The deceased had been carried out, and Qin Youwei opened the white cloth on the stretcher so that everyone could see the injuries on the front of the deceased.
The face of the deceased had also been hit hard, and one eye had been beaten into a panda eye, with deep black bruises in the eye socket.
Qin Youwei continued: "The deceased had been violated before her death and had lacerations on her lower body. I did not find any male bodily fluids in her lower body, but I found residues of suspected shower gel. It is speculated that the murderer had washed the deceased's lower body."
"So professional?" Lu Wan frowned. This was very much like a repeat offender.
"There are more professional ones!" Qin Youwei looked at the bathroom, "The bathroom floor drain has been cleaned, and no human hair was found. This murderer is interesting."
Lu Wan took a breath, "The murderer deliberately wanted us to discover the deceased!"
You know, Hu Xianglei downstairs reported the case to the police because he found blood leaking from the bathroom upstairs. When Lu Wan came over, he also found that the floor drain was blocked by a towel.
There must be hair residue from the residents in the bathroom floor drain, but the floor drain is clean, which proves that the murderer has cleaned the floor drain. Since the murderer had cleaned the floor drain, he would not have been careless enough to block the floor drain with a towel. This can only mean that the murderer did it on purpose.
Judging from the results, the murderer just wanted people to discover the deceased earlier, and naturally he also wanted the police to discover the deceased earlier!
A policeman came out of the master bedroom and said, "Team Lu, the deceased's mobile phone is missing. There are two open empty boxes in the drawer, which look like they contain jewelry. The drawer handles, wardrobe handles, and the ones on the empty boxes There are signs of damage to the fingerprints, and I judge that the murderer put wet wipes on these areas to avoid leaving fingerprints, and there were wet wipes in the room."
Zeng Hao said thoughtfully: "He did not use dry paper towels, because dry paper towels would have the risk of scratching. He used wet wipes, which wiped off some of the original fingerprints. Why does this murderer look like a habitual criminal?" "
"Have similar cases occurred in Meihai City in recent years?" Chen Xiaoxiao suddenly asked.
Lu Wan was stunned for a moment, then looked at Chen Xiaoxiao in surprise, then looked at Zeng Hao, "It definitely didn't happen a year ago. Has it happened this year?"
"Definitely not!" Zeng Hao shook his head and replied, "Except for two cases of murder and absconding, all other murder cases have been solved."
"Let Xiaokai check the system to see if there are any similar cases in other provinces and cities." Lu Wan said.
After hearing this, everyone understood what Lu Wan meant.
Zeng Hao asked in disbelief: "Liant Lu, do you think this is a serial murder case?"
Lu Wan looked at Chen Xiaoxiao, who was looking at her in surprise. Lu Wan nodded, "Judging from the murderer's method, it doesn't look like he committed the crime for the first time. He is most likely a serial killer!"
This was what Lu Wan was worried about when she left the reporter's house. She didn't expect that the possibility was getting bigger and bigger, and she didn't expect that a newcomer with almost zero experience in handling cases would have the same guess as her.
Lu Wan then said to Bai Mo: "Follow Zeng Hao and visit nearby residents and businesses to see if they found any suspicious strangers last night. If so, draw them."
Bai Mo, who had prepared a lot of words, opened his mouth and nodded helplessly.
Bai Mo is a portraitist in the police force, and it is indeed his duty to visit people for portraits, but Bai Mo feels a little uncomfortable at this moment.
From Lu Wan's tone, she already regarded him as a tool for portraits. Bai Mo, who wanted to show his self-worth, couldn't help but feel a little frustrated.
