Criminal Investigation Notes

The vomit of the deceased now smelled of bitter almonds. Lu Siyu suddenly noticed the position of Dong Fang's pillowcase, which still seemed to have some brown-black semi-dry marks.In the other stalls of vomit, something from brown to dark brown also appeared in the same place, mixed in the bloodshot, which was difficult to distinguish.

Since the source of the poison and more information have not yet been confirmed, all the evidence on the scene must be more careful.

Lu Siyu took a cotton swab and stirred up a little brown object in the vomit. The thing was sticky and melted away. He looked at the texture and frowned slightly.

Lin Xiuran saw his expression change and asked him, "Have you noticed?"

Lu Si said: "There seems to be undigested chocolate in the vomit. Several people have different dinners, but they all ate chocolate."

Chocolate can well conceal the bitter almond flavor of blue vapors, and it can also let consumers relax their vigilance.Those girls would not have imagined that the last chocolate they ate in their lives took their young lives.

Lu Siyu rummaged through several trash cans, and found a chocolate box in the one near the door, and handed it to Cheng Xiaobing, who was the material evidence.

Cheng Xiaobing deserves to be a standard foodie, and he can recognize it only by looking at it: "This is a very popular online celebrity lava chocolate recently. It is a big chocolate ball with a thick chocolate paste inside. This chocolate It’s particularly difficult to book. You need to wait in line for more than a week to get the order, and then deliver the chocolate throughout the cold chain to ensure that the chocolate is in complete shape.” She turned her head and looked at a small refrigerator under the corner of the dormitory. “It was probably stored before. over there."

Lin Xiuran nodded and confirmed: "This may be the source of the poison. It needs to be further confirmed by an autopsy."

Lu Siyu looked around and did not relax his vigilance. From a closer look, these chocolate sauces covered the entire bedroom, on paper towels, on the corners of the table... the sweet candy in the past has now become a life-killing poison.

After checking the interior, Lu Siyu went to the door and looked at it. Outside the door of the 108 dormitory, there is a deep corridor on one side and a small door on the other side. He walked over and tried to open it. The door was locked. Yes, it can only be opened from the inside, now there is no key, the lock is covered with patina again, Lu Siyu can only be folded back.

The windows in the corridor were all set up with iron bars. He looked in that direction from an open window. There was a dead corner of the dormitory building. The vegetation grew wildly here. Because it was not easy to get here, the school cleaners obviously did too. Forget about this corner, it is full of rubbish falling from upstairs.

Lu Siyu was about to turn around and leave, but suddenly heard a meow from that direction. A hint of surprise appeared on his delicate face. This place has become a paradise for stray cats.

The material evidence staff apparently found this place too, and asked the school's person in charge: "Can this door be opened?"

The person in charge was a little embarrassed: "You can open it, but the key is still on the other side of the dormitory. The outside is a palm-sized platform, surrounded by walls of several meters high, and you can't enter the thieves. It's nothing but rubbish. 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 to see."

The person in charge made a call, and not long after, an aunt in her forties went to get the key.When I walked past the door of the 108 bedroom, I couldn't wait to stick to the wall, how far I could hide.The old lady inserted the key into the door, and the old door lock creaked, and she pulled the door open with her hands, and a cold wind blew in from outside.

The two physical evidence personnel checked inside and out, and it turned out that there was no sign of entry.The old lady came to lock the door again, and babblingly said: "Last time I opened the door, a cat died outside. It smelled stinking and only found out that the dead was a black cat. This time around, he was killed. It’s evil to die. Amitabha, Amitabha."

The speaker was unintentional, the listener was intentional. Lu Siyu was aside, raised his head and asked: "Are there many stray cats on this campus?"

The aunt nodded in succession: "A lot, more than just too much. It's simply too much. In spring, people can't sleep because of the noise."

"How could a cat die here?"

"Who knows this... we don't know. 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 seemed to be puzzled why he wanted to chase after a cat and said, "It's been almost a month, and the corpse has already 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 too common for a few dead cats to die.” No one takes a few dead cats seriously.He thought for a while and added, "But it seems that a month ago, there was a time when a few died. The sanitation workers who collected garbage complained that there were many dead cats at that time."

At this time, Song Wen, who climbed up the Audi, found a set of clothes and a pair of leather shoes in the trunk as Lu Siyu said, and took his things to sit in the more spacious back seat.A protective film is affixed to the car glass on both sides of the rear seat so that the inside cannot be seen from the outside, so it can be used for changing clothes.

Song Wen put on the spare trousers worn by Lu Siyu. At this time, he finally understood what Lu Siyu meant to change together. It turned out to be a complete set of casual suits, the color was black, and the material was hanging down.Song Wen doesn't wear formal clothes very often and hasn't tried this style very much.

Although Lu Siyu looks a little thin, but he did not expect that the number of this dress is exactly the same as that of Song Wen. As the saying goes, people rely on clothing and Buddha rely on gold.Song Wen, who had changed into a suit and leather shoes, took a photo from the rearview mirror of the car. The person in the mirror was handsome, handsome and with a touch of seriousness, and the whole set of clothes fitted as if he was customized.

Song Wen didn't dare to delay too long, put on his shoes, and simply folded his clothes.As soon as he opened the door, he saw Fu Linjiang locked the car and got out of the car. The two people looked at each other for three seconds. Fu Linjiang seemed to recognize Song Wen and stepped back and asked: "Team Song! This is not your style, you... …Isn’t this about going on a date?"

Song Wen looked at his dress, which was indeed misleading, but he still relentlessly went back, "Who is coming to the crime scene in the middle of the night to date?" He hid the trousers and thought of a reasonable one. Explain, "My clothes are dirty, so I borrowed Lu Siyu's spare clothes to wear."

At the scene, various environments were complicated, and dirty clothes were a common occurrence. Fu Linjiang did not mention this matter empathetically, and asked: "What's the situation at the scene?"

Speaking of this, Song Wen became a little heavy again: "It's miserable, Lao Lin and Lu Siyu are here."

The two walked inside, and Fu Linjiang sighed: "I didn't expect that this happened in Nancheng. Every school-related case seems to cause concern."

After speaking, the two people came to the door of the crime scene. The forensic doctor and the physical evidence had already completed the basic investigation. Lin Xiuran and his assistant were also preparing to put the body in a black body bag and hurry up for an autopsy. It should be able to produce partial results.

Lin Xiuran had a face-to-face meeting with them. After seeing Song Wen’s outfit, he nodded in satisfaction and affirmed, "Team Song, you should change your style occasionally." He continued: "The scene records are almost complete, and the physical evidence is basically collected. , I collected many traces of chocolate, and found four mobile phones. The passwords have not been cracked. We focused on surveying some tableware and cups, and the water dispenser was also extracted."

Song Wen nodded and completed the handover: "Leave a camera and a bag of material evidence for us. Let's search again and ask the informant when we finish searching here."

After making the arrangements, Lin Xiuran said, "I will take the corpse away for autopsy, and withdraw it first."

Lu Siyu picked up the camera that Xiaobing handed over, turned his head to look at Song Wen, looked up and down on him, nodded in satisfaction: "Song team, you wear a good suit."

Lin Xiuran and another forensic doctor, after the two physical evidence left, the small dormitory was immediately refreshed. Song Wen walked to the window and opened the window. The smell in the room suddenly disappeared.The corpse on the ground has been lifted away, and a fixed line of the site traces has been drawn according to the final shape of the corpse for reference.

Lu Siyu handed Song Wen a few forms, and habitually licked his lips, "When you went to change clothes just now, someone from the school yard came and said a few polite remarks, you must fully cooperate with you. They also sent the school status information of four students."

Song Wen took the form and looked through it. In addition to Dong Fang and Ma Aijing who are known to have died, there are two other people on the form. They were sent to the hospital. One was called Guo Wei and the other was called Lin Wanwan. , Are still under rescue.

Lu Siyu continued: "Guo Wei was the one who ran to other dormitories to call for help and attracted attention. Lin Wanwan was the least poisoned and remained awake when she was discovered. She called 120 first, so the police and ambulance almost They came at the same time."

Song Wen looked at the four beds, tables and chairs in the dormitory: "Then let's line up, whose bed is near the door?" That bed was blue sheets, and there were some study books on the desk below. Various notes were posted, and the table was full of pens and papers, and things were a bit messy.

"This one belongs to Guo Wei, and Lin Wanwan lives across from her." Lu Siyu said. Lin Wanwan's bed sheets are plain beige, the cleanest on the desk, the least things, and not many daily necessities. , I can see that she is a more clean girl.

On the inside, the one with the pink bed sheet belonged to Dong Fang. Before she was alive, Dong Fang was a standard rich second-generation. In addition to books, she also had a laptop, some cosmetics, and a pile of chairs beside the bed. Full of clothes, the small refrigerator also looks like hers.

The last bed naturally belonged to Ma Aijing. There was a desktop computer. There were a lot of melon seed shells in the trash bin. There were some snacks on the table. Then they opened the girls' cabinets according to the number, and they corresponded to the identities.

Song Wendao: "Most of the school's drug cases are inseparable from the dormitory. You can search this dormitory carefully to see if you can find any useful clues." Compared with private houses, dormitory information is more concentrated and more capable. Obtain effective information.

The three of them rummaged in and out of the dormitory. They checked the time. It was close to three in the morning. Song Wen asked, "Linjiang, what did you find?"

Fu Linjiang said: "It's all regular things, books, materials, clothing and daily necessities. I didn't find anything special. Oh, yes, I found an apron at Lin Wanwan. It may be worn by a part-time worker. It says Two words, Xinxin. However, I searched the reviews, but I didn'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 watch."

Song Wen raised his eyebrows: "Say something you can't remember on the watch."

The things recorded on the survey sheet are relatively simple, and on-site searches often draw conclusions based on the information they see. These conclusions can be inferred, but because they are inferences, they are not easy to record.

Lu Siyu thought for a moment, then turned his head and said, "Of these four people, Dong Fang is the richest in the family, but she is careless, messy, and poor in personal hygiene; Ma Aijing has re-read for a year. She looks the most beautiful, likes to play games, likes to make friends, and she plays a popular online game recently. She plays it very frequently and should be before the lights are turned off every day; Lin Wanwan likes to be clean, she She has a different surname from her current father. She should be a stepdad. She has a younger brother who doesn’t go home often, and basically stays in the dormitory on weekends. Guo Wei is the best student, and his family is not very good. Going to work, she is a hospital-level student with a neurasthenia. She wears earplugs when she sleeps and often goes to the school hospital."

Fu Linjiang was taken aback by these words. He also saw that many things were found, but he obviously didn't think of them.Just about to interrupt, Song Wen seemed very dissatisfied, and continued to ask Lu Siyu: "You didn't just see these, did you? You know I asked you more than that."

Lu Siyu looked at Song Wen, and Song Wen tilted his head slightly, rubbing his lower lip with the thumb of his right hand and looking back at him, his dark eyes seemed to see everything.

Just now, Lu Siyu's action of searching for everything was included in Song Wen's eyes. Based on the trajectory and time of Lu Siyu's query, he can judge which clues he paid attention to.

Song Wen's eyes seemed to be asking Lu Siyu, since he saw them all, why didn't he say it? And he just reminded him last night.
