Chapter VII

"Brother Dong, why do I think we haven't gained anything substantial from coming to Mingchuan University today?" On the campus path around the parking lot of Mingchuan University, Xiao Lin and Dong Chenghai complained a little disappointed.

"Not necessarily, at least we can obtain Sima Yuanying's DNA information from his toothbrush and other daily necessities and compare it with the DNA of the deceased." Dong Chenghai took a hard puff of his cigarette and said calmly as he looked at the swirling smoke.

"It's half the effort! I always feel that the head of the department, Wang Hong, has a lot of city government, and he must be hiding something. ”

"It's inevitable to hide something, she can't sit in that position if she doesn't have any ability at that age, but it's probably not a key piece of information, she's not a fool, all she thinks about is the reputation of the school, if it's really a valuable clue, she doesn't dare to hide it."

"Although what Wang Hong and Sima Yuanying's roommate said is not in conflict, Brother Dong, do you think what they say is more credible?"

"It's all credible. Just because Wang Hong has something to hide doesn't mean that she will tell lies, and it doesn't mean anything to her. Sima Yuanying's roommates didn't need to tell lies, besides, their reaction when they saw us today was not like something they could pretend, they were surprised by our arrival, which proved that they didn't know what happened to Sima Yuanying before this, and they lacked time to prepare. ”

"So, according to the situation described by Sima Yuanying's roommate, Sima Yuanying can't be autistic, right?"

"I don't know if Sima Yuanying is autistic, but I feel that this person is definitely not an ordinary person, and we still need to continue to investigate him."

"Not an ordinary person? Why? A graduate student in philosophy, to put it mildly, is not a scholar! Xiao Lin was puzzled, and at the same time felt that Dong Chenghai had overestimated Sima Yuanying's ability.

"Judging from the information we currently have, Sima Yuanying is a withdrawn person who does not have too much communication with others, which means that he can not socialize and like to live in his own world. To put it nicely, it is to live freely, to behave completely from his own heart's will, and it just so happens that he likes to learn so much; To put it mildly, it is extremely proud, and there is no one else in his eyes except himself, not even society. This kind of person can live harmless to humans and animals, or he can become a moth that endangers society, and there is only one step between the two, and it is completely a thought. Dong Chenghai carefully analyzed it with the experience accumulated in his criminal police career for more than ten years.

"Brother Dong means that either the deceased is Sima Yuanying, or the murderer is Sima Yuanying?" Kobayashi said bluntly.

"No, I just want to explain the importance of Sima Yuanying in this case." Dong Chenghai finished speaking slowly, took the last puff of the cigarette, snuffed out the cigarette and threw it into the trash, looked at Ouyang Yunxi, who had just finished buying water in the distance and was walking like them, and continued: "By the way, is there any news about the wallet technology department?" ”

"Well, the colleagues in the technical department said that the DNA samples collected from the wallet were consistent with the DNA of the deceased after testing, but what puzzled the colleagues in the technical department was that the ID card and bank card in the wallet could not collect any information, not even fingerprints, although the hands of the deceased had been corroded by strong acid, and they did not have the conditions to collect fingerprints."

"In other words, it is the most reasonable explanation that the wallet belongs to the deceased, but the ID card in the wallet may not be the deceased?" Dong Chenghai smiled helplessly.

"Well, so to speak. However, Brother Dong ......" Xiao Lin looked like he wanted to say something, glanced at Dong Chenghai, and then said: "Brother Dong, do you say that it is possible that this wallet or ID card has been forged?" ”

Dong Chenghai glanced at Xiao Lin, and his grim eyes made Xiao Lin regret saying what he thought.

"Perhaps. It's just that if that's the case, we're not solving the case. After a long time, Dong Chenghai responded.

"What's that?"

"Fighting. It can't be described as solving a case. If your hypothesis is true, then the murderer is most likely to be Sima Yuanying, in terms of modus operandi, murderous and ruthless, not like murder, more like doing meticulous scientific research, and at the same time he not only completed his 'scientific research' perfectly, he also relied on calm and rigorous reasoning to perfectly 'deal with the aftermath', and his anti-investigation ability is not inferior to any criminal policeman in the police station. How likely is this for a graduate student? Very little. Moreover, in order to divert the attention of the police, what are the chances of leaving one's ID card at the scene and pretending to be the identity of the deceased? It's also very small. So, what are the odds of combining these two slim possibilities? In addition, how much hatred does it have to make a high-achieving student with a bright future not hesitate to pay everything related to identity, including academic qualifications, credit, etc.? Dong Chenghai felt a chill in his back.

"Hmm... The odds are really too slim and it sounds like a detective story. Xiao Lin never thought that one of his conjectures would hide so many premises behind it, and he panicked in his heart.

"Hey, give you water." Ouyang Yunxi came to Dong Chenghai's side, handed them the mineral water, unscrewed his own water and took a sip, and then said, "What are you talking about, you are talking so energetically." ”

"What else can we talk about, Sima Yuanying." Kobayashi said as he twisted the cap of the bottle.

"Still talking about him? I feel that my life in the past few days is full of the words 'Sima Yuanying'. What are you talking about? ”

"To sum up, Sima Yuanying is most likely to be a harmless innocent victim, and there is also a very small possibility of a criminal who is extremely harmful to society." Xiao Lin smiled proudly at Ouyang Yunxi.

"It's dangerous, look at you." Ouyang Yunxi looked at Xiao Lin's stupid look of "villain", and couldn't help but hit him with the mineral water in his hand.

"Stop making a fuss, get in the car." Dong Chenghai took the lead in the car.

Ouyang Yunxi glared at Xiao Lin and followed Dong Chenghai into the car.

The car drove away from the gate of Mingchuan University and turned onto the coastal road, which was more than an hour away from the rush hour, and there was no grand traffic jam on the coastal road at this time. Dong Chenghai drove a car on the coastal road. None of the three spoke, each thinking about his own thoughts.

"Yunxi, have you contacted Sima Yuanying's parents?" The quiet environment of the carriage was suddenly broken by Dong Chenghai.

"Contacted. I was about to ask you to do well, and don't let me do this kind of contact with my family in the future, but I really can't hear that desperate cry. Ouyang Yunxi remembered the scene of the phone call with Sima Yuanying's parents just now, and couldn't help but be moved again.

"Girls are more careful, more comfortable than our older men, you are the only flower in our police station, who will you let if you don't go?"

"Kill me, huh?" Ouyang Yunxi punched Dong Chenghai with a little displeasure.

"Don't make a fuss, drive. Tell me about the situation. ”

Ouyang Yunxi leaned her head on the car seat and said quietly, with a hint of sympathy between her words: "It was Sima Yuanying's mother who answered the phone, and after introducing herself, I asked her if Sima Yuanying had contacted them recently, and after getting her negative answer, I told her that the police found a body on Huangshi Beach on July 19, which was likely to be Sima Yuanying." After a few seconds, there was a moving cry of despair on the other side of the phone, mixed with an almost roaring 'he can't swim, what is he doing at the beach'. Because I was too sad to continue talking, the subsequent phone call was answered by Sima Yuanying's father, so I briefly told him the current situation of the case, although I was not as heartbroken as Sima Yuanying's mother, but I clearly felt the pain of being deliberately suppressed from the words. After Ouyang Yunxi finished speaking, she wiped away the tears from the corners of her eyes with her hand.

"What's the matter, crying? Kobayashi, get her a piece of paper. Dong Chenghai glanced at Ouyang Yunxi and said to Xiaolin.

"Can you not cry, I have worked hard to raise my son so big since he was a child, and he is still a high-achieving student, so if you don't say it, it's uncomfortable just thinking about it." Ouyang Yunxi took the tissue handed by Xiao Lin and wiped the corners of her eyes again.

"The coldest thing in the world is the impermanence of life, not to mention that white-haired people send black-haired people." Dong Chenghai said with emotion.

"I don't know if the result of Sima Yuanying's parents came over was Sima Yuanying or not." Xiao Lin glanced at Ouyang Yunxi and then at Dong Chenghai, and said to himself.

"I hope not, to be honest I'm a little unbearable." Ouyang Yunxi blew her nose, and then asked Dong Chenghai, "Brother Dong, what do you think?" ”

Dong Chenghai held the steering wheel with both hands, looked ahead with his eyes, and replied for a long time: "I, I hope it is not, but I am afraid that it is not." ”
