The vomit of the deceased now smelled of bitter almonds. Lu Siyu suddenly noticed the position of Dong Fang's pillowcase, which seemed to have some brown-black half-dry marks on it. In the other vomites, things from brown to dark brown appeared at the same time, and it was difficult to distinguish them among the vomited blood.
Since the source of the poison and more information have not yet been confirmed, all evidence at the scene must be taken with greater care.
Lu Siyu took a cotton swab and picked up a bit of the brownish brown object in the vomit. It was sticky and melted at once. He looked at the texture and frowned slightly.
Lin Xiuran saw the change in his expression and asked him, "Have you found anything?"
Lu Siyu said: "There seems to be undigested chocolate in the vomit. Several people have different dinners, but they all ate chocolate."
Chocolate can mask the bitter almond taste of green gas well, and it can also let the eater relax his vigilance. Those girls would never have thought that the last chocolate they ate in their lives took their young lives.
Lu Siyu rummaged through a few trash cans, found a chocolate box in the one by the door, and handed it to Cheng Xiaobing, who was the physical evidence.
Cheng Xiaobing is worthy of being a standard foodie, and he recognized it just by looking at it: "This is the Internet celebrity lava chocolate that is very popular on the Internet recently. It is a big chocolate ball with a thick chocolate syrup inside. This kind of chocolate It is very difficult to make reservations, you have to wait in line for more than a week to order, and then the whole process of cold chain transportation can ensure the complete shape of the chocolate." She turned to look at the small refrigerator under the corner of the dormitory, "It was probably stored before. there."
Lin Xiuran nodded and confirmed: "This may be the source of the poison. The specifics still need to be further confirmed by autopsy."
Lu Siyu looked around, but did not let his guard down. Looking closely, these chocolate sauces covered the entire bedroom, on paper towels, on the corner of the table... The sweet candies in the past have now become life-threatening poison.
After checking the room, Lu Siyu went to the door to take a look. Outside the door of dormitory 108, there was a deep corridor on one side and a small door on the other side. He walked over and tried to open it, but the door was locked. Yes, it can only be opened from the inside, there is no key now, and the lock is covered with rust again, so Lu Siyu can only fold it back.
The windows in the corridor were all set with iron bars, and he looked in that direction from an open window. It was a dead corner of the dormitory building, where vegetation was growing wildly, because it was not easy to get here, and the school cleaners obviously did not. Forget about this corner, it's full of rubbish that fell from upstairs.
Lu Siyu was about to turn around and leave, but suddenly heard a cat meow from that direction, a hint of surprise appeared on his delicate face, this place has become a paradise for stray cats.
The physical evidence officer apparently found this place and asked the person in charge of the school, "Can this door be opened?"
The person in charge was a little confused: "It can be opened, but the key is still on the side of the house, outside is a platform the size of a palm, surrounded by walls several meters high, no thieves can get in, except for garbage, it's really nothing. We basically clean it once in the first half of the year."
Lin Xiuran said: "We are also doing things according to the regulations. Let's open this door and take a look."
The person in charge made a phone call, and not long after, an aunt in her 40s went to pick up the keys. When I walked past the door of dormitory 108, I wanted to stick to the wall, how far I could hide. The aunt inserted the key into the door, and the old door lock made a creaking sound. She pulled the door open with both hands, and a cold wind blew in from outside.
The two physical evidence officers checked it inside and out, and sure enough, there was no sign of entry. The aunt came to lock the door again, and rambled: "Last time I opened the door, a cat died outside, and it smelled bad, only to find out that it was a black cat that died, and this turned out to be fatal. Dead people are really evil. Amitabha, Amitabha."
The speaker was unintentional, but the listener was intentional. Lu Siyu stood aside, raised his head and asked, "Are there many stray cats on this campus?"
The aunt nodded in succession: "It's too much, it's too much, it's too much. In spring, the noise is so noisy that people can't sleep."
"How did the cat die here?"
"Who knows this... We don't know either. Maybe it's sick, maybe bitten by a dog."
Lu Siyu thought for a while and asked, "Is the dead cat's body still there?"
The aunt didn't seem to understand why he was chasing after a cat and said, "It's been almost a month, and the body has been thrown away."
The person in charge of the school on the side also said: "There are so many cats in this yard, it's not unusual for a few to die." No one would take a few dead cats seriously. He thought for a while and added, "But it seems like a month ago, a few died, and the sanitation workers who collected the garbage complained that there were a lot of dead cats at that time."
At this time, Song Wen, who climbed into the Audi, found a set of clothes and a pair of leather shoes in the trunk that Lu Siyu said, and took the things and sat in the more spacious back seat. A layer of protective film is attached to the glass on both sides of the rear seat, so that the inside cannot be seen from the outside, just enough to change clothes.
Song Wen put on the spare pants that Lu Siyu had brought. At this time, he finally understood what Lu Siyu meant to change together. It was actually a complete set of casual suits, the color was black and the material was dangling. Song Wen doesn't often wear formal clothes, so he hasn't tried this style very much.
Although Lu Siyu looked a little thin, he didn't expect that the number of the clothes was exactly the same as Song Wen's. As the saying goes, people rely on clothes, and Buddhas rely on gold clothes. Song Wen, who had changed into a suit and leather shoes, took a look at the rearview mirror of the car. The man in the mirror was handsome and dashing, with a hint of seriousness in it.
Song Wen didn't dare to delay too long, put on his shoes, and simply folded his clothes. As soon as the door was opened, Fu Linjiang locked the car and got out of the car. The two looked at each other for three seconds. Fu Linjiang seemed to recognize Song Wen, took a step back and asked, "Team Song! This is not your style, you... Isn't this about going on a date?"
Song Wen looked at his outfit, which was indeed misleading, but he mercilessly turned back, "Who are you dating at the crime scene in the middle of the night?" He hid the floral pants and thought about a reasonable Explain, "My clothes are dirty, so I borrowed Lu Siyu's spare clothes to wear."
At the scene, all kinds of environments are complicated, and dirty clothes are a common occurrence. Fu Linjiang understandingly didn't mention it again, and asked, "How is the situation at the scene?"
Speaking of this, Song Wen became a little heavy again: "It's very miserable, Lao Lin and Lu Siyu are here."
The two walked in. Fu Linjiang sighed and said, "I didn't expect such a thing to happen in Nancheng. Every school-related case seems to attract attention."
As they spoke, the two came to the door of the crime scene. The forensic doctor and physical evidence had already completed the basic investigation. Lin Xiuran was also preparing to put the body into a black body bag with his assistant. There should be some results.
Lin Xiuran had a face-to-face with them, and nodded with satisfaction after seeing Song Wen's outfit, affirming, "Song team, you should change your style occasionally." He continued: "The scene record is almost complete, and the collection of physical evidence is basically complete. , We collected traces of chocolate in many places, found four mobile phones, and the password has not been cracked. We focused on some tableware and cups, and also extracted the water dispenser."
Song Wen nodded and completed the handover: "Leave a camera and a physical evidence bag for us, let's search again, and ask the reporter when we're done searching here."
After making arrangements, Lin Xiuran said, "I'll take the body away for an autopsy, and leave it first."
Lu Siyu took the camera that Cheng Xiaobing handed over, turned his head to look at Song Wen, his eyes circled up and down on him, and nodded with satisfaction: "Song team, you are well dressed in this outfit."
After Lin Xiuran and another forensic doctor, the two physical evidences left, the small dormitory suddenly became much refreshed. Song Wen walked to the window, opened the window, and the smell in the room dissipated a lot. The corpse on the ground has been carried away, and according to the final shape of the corpse, a fixed line for the site traces has been drawn for reference.
Lu Siyu handed Song Wen a few sheets, and licked his lips habitually, "When you went to change your clothes just now, someone from the school came and said a few polite words, you must cooperate fully, etc. They also sent the student registration materials 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 people on the form. The two were sent to the hospital. One was Guo Hua and the other was Lin Wanwan. , are still being rescued.
Lu Siyu continued: "Guo Hua was the one who ran to the other dormitory to call for help and attracted attention. Lin Wanwan was the least poisoned and was basically awake when she was found. She called 120 first, so the police and ambulance almost came at the same time."
Song Wen looked at the four beds and the tables and chairs in the dormitory: "Then let's line up. Whose is the bed near the door?" The bed was a blue sheet, and some study books were placed on the desk below. All kinds of sticky notes were posted, the table was full of pen and paper, and things were a bit messy.
"This one belongs to Guo Wan, and the one who lives opposite her is Lin Wanwan." Lu Siyu replied, Lin Wanwan's sheets were plain beige, and the desk was the cleanest, with the fewest things and not many daily necessities. , It can be seen that she is a girl who loves cleanliness more.
On the inside, the pink sheet belonged to Dong Fang. Before her death, Dong Fang was a standard rich second-generation. In addition to books, there was a laptop on her desk, some cosmetics, and there were piles on the chair beside the bed. Full of clothes, the small refrigerator looks like hers too.
The last bed was naturally Ma Aijing's. There was a desktop computer. There were a lot of melon seed shells in the trash can, and there were some snacks on the table. Then they opened the girls' cabinets according to the number and corresponded to their identities one by one.
Song Wendao: "Most of the school's poisoning cases are inseparable from the dormitory. You can carefully search this dormitory to see if you can find any useful clues." Get valid information.
The three searched in and out of the dormitory, looked at the time, and it was almost three in the morning when Song Wen asked, "Linjiang, what did you find?"
Fu Linjiang said: "It's all conventional things, books, materials, clothing and daily necessities, and I didn't find anything special. Oh, by the way, I found an apron at Lin Wanwan's place. It may be worn by part-time workers. It says Two words, Xinxin. But I searched around for reviews and couldn't find a restaurant called Xinxin nearby."
Song Wen turned his head and asked Lu Siyu, "What about you? What did you find?"
Lu Siyu raised the record sheet in Yang's hand: "It's all recorded on the sheet."
Song Wen raised his eyebrows: "Tell me what you can't remember on the watch."
The things recorded on the survey form are relatively simple, and the on-site search often leads to some conclusions based on the information seen. These conclusions can be inferred, but because they are inferences, it is difficult to record.
Lu Siyu thought for a moment, then tilted his head and said, "Among the four, Dong Fang is the richest in the family, but she is careless, her things are cluttered, and her personal hygiene is poor; Ma Aijing has read it for a year. , she is the most beautiful, she likes to play games, she likes to make friends. Recently, she is playing a popular online game. She plays very frequently, it should be every day before the lights go out; Lin Wanwan is the most clean, she She has a different surname from her current father. She should be her stepfather. She has a younger brother at home. She doesn't go home often and usually stays in the dormitory on weekends. Guo Hua is the best student, but her family is not very good. When she went to work, she was a good student at the hospital level and suffered from neurasthenia. She had to wear earplugs to sleep, and she often went to the school hospital."
Hearing these words, Fu Linjiang was taken aback for a moment. He also saw that he had found a lot of things, but he obviously didn't think of them. Just as he was about to interject, Song Wen seemed very dissatisfied, and continued to ask Lu Siyu: "You don't only see this, do you? You know that I ask you more than that."
Lu Siyu looked at Song Wen, Song Wen turned his head slightly, wiped his lower lip with his right thumb, looked back at him, his dark eyes seemed to see everything.
Just now, Lu Siyu's action of rummaging through everything was in Song Wen's eyes. Based on the track and time of Lu Siyu's query, he could judge which clues he paid attention to.
Song Wen's eyes seemed to be asking Lu Siyu, since he saw it, why didn't he say it, and he just reminded him last night.
