Criminal Investigation Notes

The vomit of the dead smelled of bitter almonds. Lu Si Yu suddenly noticed the position of Dong Fang's pillow case. There were some brown and black semi dry marks on it. In other vomit stalls, brown to dark brown appeared in the vomit, which was difficult to distinguish.

Since the source of the poison has not been identified and more information has yet to be confirmed, all evidence at the scene must be more careful.

Lu Siyu took a cotton swab and picked up the brown lump in the vomit. It was sticky and soon melted away. He looked at the texture and frowned slightly.

Lin xiuran saw his expression change and asked him, "have you found it?"

"The vomit seems to contain undigested chocolate. Several people have different dinners, but they all eat chocolate," he said

Chocolate can cover up the bitter almond flavor of the green gasification, and let the consumers relax their vigilance. Those girls would not have thought that the last chocolate they ate in their lives took their young lives.

Lu Si language rummages through a few dustbins and finds a chocolate packing box in the one near the door and hands it to Cheng Xiaobing.

Cheng Xiaobing is indeed a standard food. After a little look, he recognized: "this is the Internet red lava chocolate, which is very popular on the Internet recently. It is a big chocolate ball, which is wrapped with thick chocolate thick paste. This kind of chocolate is particularly difficult to book. You need to wait in line for more than a week before you can order it, and then the whole cold chain delivery can ensure the integrity of the chocolate shape She turned her head and looked at a small refrigerator under the corner of the dormitory. "It was probably stored there before."

Lin xiuran nodded to confirm: "this may be the source of poison. The specific anatomy needs to be further confirmed. "

Lu Si Yu looked around, but he didn't relax his vigilance. If you look at it carefully, the whole bedroom is covered with chocolate sauce, on paper towels, on the corner of the table Sweet candy in the past has become a deadly poison.

After checking the room, Lu Siyu went to the door again. Outside the door of the 108 dormitory, there was a deep corridor on one side and a small door on the other side. He went over and tried to open it. The door was locked and could only be opened from the inside. Now there is no key, and the lock is covered with copper rust, so Lushi language can only turn back.

The windows in the corridor have iron bars. He looks from an open window in that direction. It is the dead corner of the dormitory building. The vegetation is growing wildly here. Because it is not easy to access here, the school cleaners obviously forget this corner, which is full of garbage falling from upstairs.

Lu Si Yu was about to turn around and leave, but suddenly he heard a cat call coming from that direction. A little surprise appeared on his pretty face. This place has become a paradise for stray cats.

The physical evidence personnel obviously also discovered here, asked the school's person in charge: "can this door open?"

The person in charge was a little bit worried: "yes, it can be opened, but the key is still there. It's a big platform outside, surrounded by a few meters high walls, so you can't get into it. Except for garbage, it's nothing. We clean it basically once in the first half of the year. "

Lin xiuran said: "we also do things according to the regulations. Let's open the door and have a look."

The person in charge made a phone call. Shortly after that, a lady in her forties went to get the key. When passing through 108 bedroom door, I wish I could stick the wall, how far can I hide. The old woman put the key into the door, and the old door lock creaked. She pulled the door open with her hands, and a cold wind came in from the outside.

Two physical evidence personnel inside and outside the inspection, it is sure that there is no trace of entry. The aunt came to lock the door again and said in a garrulous way: "the last time I opened the door, there was a cat died outside. When the smell smelled, I found out that the dead cat was a black cat. Then I would die. It's really evil. Amitabha, Amitabha. "

The speaker didn't mean it, but the listener intended to. Lu Si Yu raised his head and asked, "are there many stray cats in this campus?"

The aunt nodded: "more, more than more, it's just too much. In spring, people can't sleep because of the noise."

"How could a cat die here?"

"Who knows We don't know. Maybe I was sick, maybe I was bitten by a dog

Lu Si Yu thought for a while and then asked, "is the dead cat's body still there?"

The aunt seemed to be puzzled why he had to chase after a cat and said, "it's been nearly a month, and the body has been thrown away."

One side of the school official also said: "the yard so many cats, die a few too common." No one takes dead cats seriously. He thought for a while and added, "but it seems that a month ago, a few died, and the garbage collectors complained that there were many dead cats at that time."

.

at this time, Song Wen, who climbed on the Audi, found a suit of clothes and a pair of leather shoes in the trunk of the car mentioned by Lu Si language. He took the things and sat in a more spacious back seat. There is a protective film on the glass on both sides of the rear seat. You can't see inside from the outside, so you can change clothes.

Song Wen put on his spare pants. At this time, he finally understood the meaning of changing together. It was actually a whole set of casual suits. The color was black and the material was drooping. Song Wen doesn't often wear formal clothes and has not tried this style very much.Although the Lushi language looks a little thin, I didn't expect that the number of the clothes was exactly the same as that of the Song Dynasty. As the saying goes, people depend on clothes, while Buddhists rely on gold clothes. Song Wen, who changed into a suit and leather shoes, took a look from the rearview mirror of the car. The man in the mirror was handsome and handsome, with a trace of solemnity. The whole suit fit perfectly and almost like it was customized for him.

Song Wen didn't dare to delay for too long. He put on his shoes and simply folded his clothes. As soon as he opened the door, he saw that Fu Linjiang locked the car and got out of the car. Two people looked at each other for three seconds. It seemed that Fu Linjiang recognized Song Wen and stepped back and asked, "Song team! It's not your style. You It's not about going on a date, is it

Song Wen looked at his own dress, which was really misleading, but he still refused mercilessly and said, "who are you dating at the crime scene in the middle of the night?" He hid the flowered trousers and thought of a reasonable explanation. "My clothes are dirty. I borrowed the spare clothes in Luxi to wear them."

At the scene, a variety of complex environment, dirty clothes is often the case, Fu Linjiang understanding did not mention this matter, opened his mouth and asked: "how is the scene?"

Mention this stubble, Song Wen is somewhat heavy again: "quite miserable, Lao Lin and Lu Si language in."

As they walked inside, Fu Linjiang sighed: "I didn't expect this kind of thing happened in Nancheng. Every school related case seems to attract attention. "

With these words, the two men came to the door of the crime scene. The basic investigation of forensic medicine and physical evidence had been completed by this time. Lin xiuran also prepared to put the corpse into the black body bag with his assistant. If he grasped the time to carry out the autopsy, he should have got some results in the morning.

Lin xiuran and they were facing each other. After seeing Song Wen's dress up, he nodded his head and said, "Song team, you should change your style occasionally." He continued: "the scene records are almost complete, and the material evidence has basically been collected. We have collected many traces of chocolate, found four mobile phones, and the password has not been cracked. We have mainly investigated some tableware and cups, and the water dispenser has also been extracted."

Song Wen nodded and completed the handover: "leave a camera and a material evidence bag for us. We will search again and ask the reporter when we have finished searching here."

After making the arrangement, Lin xiuran said, "I will take the corpse for autopsy and withdraw first."

Lu Si Yu received the camera that Xiaobing handed over. She turned her head and looked at Song Wen. She turned her eyes around him and nodded with satisfaction: "Song team, you are very well dressed in this suit."

Lin xiuran and another forensic doctor, after the two physical evidence left, the small dormitory suddenly became much cooler. Song Wen went to the window and opened the window, and the smell in the room suddenly disappeared. The corpse on the ground has been lifted away. According to the final shape of the body, the site trace fixed line is drawn for reference.

Lu Siyu handed several forms to Song Wen and licked his lips habitually. "Just now when you went to change clothes, someone came to the school and said a few polite words. What's more, they also sent the student status information of four students. "

Song Wen took the form and looked at it. In addition to Dong Fang and Ma Aijing, who were known to be dead, there were two more on the form. One was Guo Zhen and the other was Lin wanwan. They are still under rescue.

Lu Si Yu continued: "Guo Zhen was the one who went to other dormitories to call for help and attracted attention. Lin wanwan was the least poisoned and remained awake when he was found. At the same time, the police and the ambulance came first

Song Wen looked at the four beds and tables and chairs in the bedroom: "let's row, whose bed is near the door?" The bed is a blue sheet. There are some study books on the desk under it. All kinds of notes are pasted on it. The desk is full of paper and pen. Things are a little messy.

"This one belongs to Guo Zhen. Lin wanwan lives opposite her." At least, the most clean thing about the girls' desk is that they don't clean their bed sheets.

The pink sheet on the inside belongs to Dong Fang. Before she died, Dong Fang was a standard second-generation rich man. Besides books, she also had a laptop, some cosmetics, and a chair beside the bed was full of clothes. It seemed that the small refrigerator was also hers.

The last bed, of course, was ma Aijing's, with a desktop computer. There were many melon seed shells in the garbage can and some snacks on the table. Then they opened the girls' cabinets according to their numbers and matched their identities one by one.

Song Wen said: "most school poisoning cases are closely related to the dormitory. Please search the dormitory carefully to see if you can find any useful clues." Compared with residential buildings, dormitory information is more centralized, more effective information can be obtained.

Three people in the bedroom inside and outside looking, looked at the time, close to three o'clock in the morning, Song Wen asked: "Linjiang, what did you find?"

Fu Linjiang said: "they are all conventional things, books, materials, clothes and daily necessities. Nothing special has been found. Oh, by the way, I found an apron in Lin wanwan. It may be worn by a migrant worker. There are two words on it, Xinxin. But I searched a circle of reviews, but I didn't find a restaurant called Xinxin nearby. "Song Wen turned his head and asked Lu Si Yu: "what about you? What did you find? "

Lu Si raised the record table in his hand: "it's all recorded on the table."

Song wentiao eyebrow: "said that the table can not remember."

What is recorded on the survey form is relatively simple, but field search often infers some conclusions based on the information seen. These conclusions can be inferred, but they are not easy to record because they are inferences.

Lu Siyu pondered for a moment, then turned his head and said: "among the four people, Dong Fang is the richest in the family, but she is careless, her things are arranged in disorder, and her personal hygiene is poor. Ma Aijing has read it again for a year, and she is the most beautiful. She likes to play games and make friends. Recently, she plays a popular online game. She plays a high frequency and should turn off the lights every day Before; Lin wanwan is the most clean, she and her father now different surname, should be stepfather, her family has a younger brother, usually do not go home, weekend also basically stay in the dormitory; Guo is the best study, family is not very good, won a scholarship, occasionally to work, she is a hospital grade three good students, neurasthenia, sleep to wear ear plugs, often run to the school hospital

This words listen to Fu Linjiang a Leng, he also saw to search a lot of things, but obviously did not associate with these contents. Just as he was about to cut in, Song Wen seemed very dissatisfied. He continued to ask Lu Siyu, "you can't just see these things? You know I asked you more than that. "

Lu Siyu looks at Song Wen. Song Wen slightly turns his head and wipes his lower lip with his right thumb. Looking back at him, his dark eyes seem to have insight into everything.

Just now, the movement of searching for everything in Lushi language came into Song Wen's eyes. According to the track and time of Lushi language's inquiry, he can judge which clues he paid attention to.

Song Wenna's eyes seem to be questioning the landing secretary. Since he has seen all of them, why not say it? And he just reminded him last night.
