Chapter 25 Chapter 24 Tracking

Inside the room, fell into silence for a while, Su Yi looked at the big boy Rock in front of him, and hesitated for a while, should he tell him the details?Later, when he saw the anxiety in Yan Yan's eyes, Su Yi couldn't bear it. He paused for a long time before revealing the real cause of Bai Xue's death: "She died of suffocation." Rock was stunned, these words were like a heavy bomb, he was knocked out, and he couldn't recover for a while.How is this possible, Bai Xue died of suffocation?Seeing the doubt and bewilderment in Yan Yan's eyes, Su Yi said slowly: "Yes, we have done an autopsy on the corpse, and the blood inside the corpse showed a dark red flow, spotting bleeding on the visceral serosa surface, and visceral congestion. It is a clear symptom of suffocation."

"But, but her eyes?" This was the most concerned question for Rock. Su Yi shook his head lightly. He took out a cigarette from his pocket and lighted it lightly. Then he revealed another surprising result - after Bai Xue's autopsy, the forensic doctor found a cigarette in her stomach. Plenty of "prednisone". Rock was terrified: "A lot of prednisone?" "Well——" Su Yi nodded and continued: "You are a medical student, so you should know the effect of prednisone. Corticosteroid-sensitive ocular inflammation has a therapeutic effect. However, if you take excessive prednisone, muscle weakness, muscle atrophy, hypokalemia syndrome, pancreatitis, peptic ulcer and other symptoms will occur. There may even be Some psychiatric symptoms, such as euphoria, agitation, restlessness, delirium, and disorientation, can also manifest as depression. According to the forensic doctor, after a dose of prednisone 40 mg per day, the above symptoms can appear within a few days of medication."

Rock was stunned, but Su Yi's following words made him even more disturbed: "We have already consulted with experts. In fact, overdose of prednisone can also cause retinal phlebitis, also known as youthful recurrent retinal vitreous hemorrhage. By Henry Eales In 1882, the relationship between vitreous hemorrhage and retinal veins was first clarified and reported in detail, so it is also called Eales disease. It is characterized by retinal and vitreous hemorrhage in both eyes. The initial lesion is in the peripheral part of the retina, and the amount of hemorrhage is small and often asymptomatic , when the amount of blood enters the vitreous, the patient will only feel a black shadow floating in front of his eyes. When the disease progresses further, when a large amount of vitreous hemorrhage occurs, the vision will drop sharply, and even cause retinal detachment leading to blindness..."

"Eales' disease?" Rock suddenly exclaimed. He is a medical student, so he has heard of this disease for a long time.It is said that if you get the disease, you will feel slightly blurred vision or have symptoms similar to floating mosquito hallucinations within a few days.Subsequently, the vision is reduced to only recognize fingers in a short period of time, or even only the perception of light.When the lesion is located in a large vein and the amount of bleeding is large, it breaks through the inner limiting membrane and enters the vitreous.The retina at the lesion is mildly edematous and opaque, and sometimes adjacent arterioles are involved, white sheaths appear or are covered by exudation.

At this time, Rock finally understood that because Baixue took a large amount of prednisone, she caused periretinal phlebitis, and the disease caused blood to gush out of her pupils, which made everyone think that she was suffering from split pupils. and die.Suddenly, Yan Yan's heart trembled, Bai Xue was like this, what about his mother?Is it also for the same reason?Rock felt chills down his spine, who was behind this, and who put a lot of prednisone in Bai Xue's food? Seeing the stunned rock, Su Yi patted him on the shoulder and sighed: "Dai Shanshan's cause of death is a bit strange. Although she committed suicide by jumping off a building, it was a little impulsive... After our understanding, Dai Shanshan's character Very lively, not such a girl who is easy to commit suicide, if after the autopsy, she also contains excessive prednisone in her body - the bureau will combine the two cases into one, maybe it is the same murderer .”

Rock agrees with Su Yi's point of view, but he is still a little puzzled: "There is nothing wrong with Shanshan's eyes." Su Yi was silent, and said softly: "After taking an overdose of prednisone, the eyes will not bleed for a while, but due to the strength of the medicine, the user will first have some mental symptoms, such as euphoria, excitement, restlessness, delirium, and disorientation. Obstacles and so on. Of course, this is just speculation, and further autopsy is needed to confirm this.” Immediately, Su Yi changed the subject: “By the way, please don’t leave this place recently, because you are The key person in this case is of course our number one suspect, and I hope he can cooperate with our investigation work."

"What, I'm the first suspect?" Rock's melancholy eyes suddenly widened. "Yes, because these cases are inextricably linked with you. Baixue died that night after dating you; Yiling also encountered an accident after returning to school from the villa in the mountain with you; There is Dai Shanshan, she followed you back to her hometown, and the result is also... Rock, I hope you can cooperate with our work, the clearer will clear himself, we pay attention to evidence in handling cases, we will not let a bad person go, but we will never be wronged A good man..." After saying these words, Su Yi turned and left.

Su Yi left, and the dormitory fell into an inexplicable silence again.The rock walked slowly to the window, his eyes looked out, and there was a basketball court not far away——his thoughts returned to that midnight, when a woman stood in the middle of the basketball court, a flash of lightning flashed across her pale face. I saw a pair of terrifying eyes, big eyes showing a kind of resentment... Who is that woman? When he came back to his senses, the rock drew the gray curtains, and the room was suddenly much darker. His classmates are all in class, but he has no intention of going to the classroom. Going to the classroom now will definitely attract countless surprised eyes-this makes Rock's heart very painful. At this time, he finally understands what loneliness and grievance are.

Let's go for a walk, Yan Yan could no longer bear such loneliness and loneliness, he slowly walked out of the dormitory. The campus is so quiet, the rock is walking slowly, he looks up and looks around, there is no one around, the sun shines through the big trees on the ground, spots like copper coins one by one.The rock stepped on those irregular circles, but the red comb suddenly popped up in my mind... Oh, I forgot if I didn’t remember it now, Shanshan handed the red comb to herself, and after she came back, the two of them together He returned the comb to Yi Ling, but he didn't expect Shanshan to leave just like that... Yan Yan touched the red comb in his trouser pocket, sweating a lot in his hand.

I should go and see Shanshan—— Yan Yan thought about it, and felt sad again.He was stunned for a quarter of an hour, and when he came back to his senses, he finally walked out of the campus quickly. Cars were coming and going on the road, Yan Yan was about to cross the road to take a taxi, but he was a little absent-minded, and his body almost hit the passing car, causing bursts of cursing.He stood blankly in the middle of the road, looking at the endless stream of cars, feeling a little at a loss. "Beep beep!" The beeping of the car was endless, and the yelling was also one after another: "You are looking for death!" Yan Yan's expression froze, he finally recovered, and quickly ran to the side of the road, holding a big tree with both hands Straight up panting.

After calming down for a while, Rock took out his mobile phone and called Police Officer Su, asked where Dai Shanshan's body was stored, and learned that the body was temporarily stored in the funeral parlor—Yan Yan said thank you, and put the phone back in his pocket. Standing on the side of the road waiting for the bus, Yan Yan’s eyes looked around boredly. There was a bus stop next to him. There were many people waiting for the bus. Everyone looked tired. Some were looking around, some were looking at their mobile phones, and some People are reading newspapers... with different expressions, but everyone has the indifference that keeps people thousands of miles away.From Rock's point of view, their faces seemed to be wearing a thick mask, and they couldn't see the true appearance of these people... Another bus came by and looked in through the window. There were so many people inside. Many people crowded together, feeling like being squeezed into persimmons.Also, there are always a lot of people in Beishi, and the bus is always overcrowded.Just when Rock was about to look away, he suddenly saw a pair of eyes in the crowd, looking out through the gap... Rock was startled for a moment, the eyes were so familiar, as if he had seen them somewhere before. "Ah!" Rock suddenly let out an exclamation from his throat, and a pair of eyes vaguely appeared in his mind. It was after Shanshan jumped off the building, when Rock rushed downstairs and saw the blooming red flower... he His head was stunned for a moment, his body was on the verge of falling, but just when he was about to fall to the ground, he saw a blurred face in the crowd, with a strange smile on his mouth, especially those eyes that left him Impressive, it seems to be exactly the same as the pair of eyes on the car. Rock leaned aside, trying to identify the color and appearance of the man's coat, but the man suddenly turned around, and Rock only saw a figure in a gray coat.At this time, the bus stopped for a while and stuffed more than a dozen people into it, and then drove away like an old cow.Rock suddenly came to his senses. He hurriedly reached out to stop a taxi, and said hurriedly after getting on the bus, "Master, follow the bus ahead." Although there were a lot of people on the bus, the speed was actually very fast. I saw that the car slipped into the gap, and it drove no worse than the car next to it. Seeing that the car disappeared, Rock hurriedly wiped his sweat: " Master, please hurry up, hurry up!" The taxi driver rolled down the window, looked around, bit his lower lip, and muttered: "Your uncle, I still can't believe that I can't catch up with your broken bus!" After adding the accelerator, the speed of the taxi was obvious. After lifting it up and seeing the bus in front again, Rock let out a long sigh of relief. When they arrived at the station, the people in the car were walking down one by one. The rock's eyes stared carefully, but no one in gray clothes was found.He couldn't help being a little discouraged, and leaned his body on the car seat, his face full of disappointment and exhaustion. The taxi driver took the opportunity to ask: "I said young man, are you still leaving?" "Go, follow the bus all the time, and I'll tell you when it stops." There was a look of determination in Yan Yan's eyes.At this moment, Rock's heart felt as if he had knocked over a bottle of five flavors, and there were all kinds of smells... He was guessing, could this person have anything to do with Shanshan's death?Although he just passed by and didn't see the person's face clearly, there is a sense of familiarity in the dark, which surprised Rock the most.He rubbed his sore temples, trying to calm himself down. The bus continued to move forward, and people got off and got on the bus one after another—Rock's eyes were fixed on him all the time, but unfortunately, he didn't find the person in gray clothes... Rock did not give up, he let the taxi follow him all the time. It was getting darker, and the surroundings became much quieter.Looking out of the rock, it seems to have come to the suburbs, and even saw farmland and cottages.At this time, even the driver was a little confused. He looked at the rock next to him from time to time, and occasionally asked, "Would you like to continue following?" At the beginning, the rock responded with a few words, but finally he didn't bother to speak, just nodded. The driver was bored, so he stopped talking and concentrated on driving.Finally, the bus in front stopped again, and after a long time, I saw a person walking down from it, wearing a gray coat—— Rock’s eyes widened in an instant, seeing that person put the hat on his head, and went back and forth After a few glances, he walked forward slowly. After paying the money and getting off the car, Rock secretly followed him.Although he had just paid more than 200 yuan for the fare, Yan Yan didn't feel any distress. On the contrary, he felt pleasant surprises in his heart.Yes, the person in front is a key person, this trip is the right time... As night fell, everything was about to be hidden under darkness, and the rock did not dare to relax a little bit. He took very light steps, lest the people in front would hear any movement.Fortunately, the person in front was just walking with his head buried. He was not very tall, and he walked very lightly, which made the rock a little regretful. Judging from the walking posture, he seemed to be a woman? Full of doubts, the rock continued to follow. At the beginning, the road under his feet was asphalt, but later it turned into soft ground, and the surrounding area was very desolate... Rock's heart was a little uneasy, he didn't know where it was leading?I don't know who the person in front is?But there is a voice in my mind calling me to follow, keep following... There is an extra house in sight, it is the kind of brick and tile house, the two rooms are silent in the twilight, it looks very inconspicuous.The person in front finally stopped, and she unlocked the door and entered the courtyard. With the sound of closing the door with a "squeak", the surroundings returned to a deathly silence.When people entered the room, the lights came on, and the rock thought for a while, and quietly climbed up the wall. Lie on the top of the wall and look in, there is a shadow walking back and forth in the room, it looks like the person just now.Rock didn't want to wait any longer. He saw that the wall wasn't very high, so he jumped down from the top of the wall. With a slight landing sound, the shadow in the house came towards the door—— Rock hurriedly hid behind the firewood pile. He looked at the door and then went back to the room. Seeing that there was no one at the door, Rock tiptoed over... When he came to the window sill, Rock carefully looked out: the furnishings in the room were very simple.Not only that, but even a little crude, with a table, two stools, and a stove, nothing else. The figure was looking at something with his back turned to him, his shoulders shrugged, as if crying.At this time, Rock finally determined that he was following a woman.However, judging from the back, she is not too young, and the silver threads on her head can be seen everywhere. From this, it can be inferred that this woman is at least 50 years old... Seeing the back of the woman crying, Shi Yan was distracted for a moment.At this moment, the woman suddenly turned her head... In an instant, Shi Yan finally saw the man's face clearly, and he exclaimed in surprise: "Ah, it's her!" Perhaps hearing the movement outside, the woman stepped forward a few steps Going to the door and quickly opened the door, shouting: "Who?" Knowing that she couldn't hide anymore, the rock hiding under the window slowly moved to the door. The woman stared at the rock in astonishment, and was so shocked that she couldn't say a word for a long time. One sentence: "You, come in." At this time, the rock was full of surprise, doubt and perseverance, but more sad—yes, he would never have thought that those eyes would be Aunt Xue.
