On the second day, I always felt that this was something strange.
It is not that there is no precedent for receiving two cases in a row within two days, but the conflict between the two makes it difficult to think that this is a coincidence.
Especially after studying Ma Jun's resume.
He has a junior high school education, is unemployed and comes from a rich family, but he lives alone. Even his biological sister said that he is not familiar with him. After Song Qiaoyu investigated Ma Jun's neighbors, he discovered that they didn't even know who lived next door, and thought that Ma Cheng, who had often visited his son, was a house speculator.
If it weren't for the existing traces of life that verified that Ma Jun had indeed lived here, I really couldn't believe that someone could live in such a situation - living in an apartment building for seven years without even having a security guard. I know there is someone living here. What state has this reached?
"At least he has to buy something to eat, right? What a hell." Song Qiaoyu listened to the content of the interview he had recorded again, with an indescribable expression, a vivid look of a destroyed world view, "Even if he really has any special channels ...There must be kitchen waste after he eats, right? Don't tell me he can even eat the wrapping paper."
ww
"Who told you that he ate fast food?" Shao Zi frowned and looked at his phone, "Didn't you go to his kitchen? Obviously, it's not surprising that the refrigerator was emptied - after all, he was going to I've been home for several days. You didn't look at the cupboard. Several bowls are neatly arranged. Brother Jiang said there is still a smell of dishwashing liquid, but it has been cleaned a little, so it is obviously used. "
"Is that so?" Song Qiaoyu looked a little embarrassed and scratched her head.
"It's normal to have this subjective impression," I sighed, "After all, we just crawled out of the garbage dump yesterday. By the way, don't you think this Ma Jun's character... is a bit familiar?"
"Captain, do you know him?" Lu Bo was obviously not in the situation. He lay on the table and turned his head with an expression as if he had just woken up. "That's my condolences. This man died peacefully... right? "
"I mean, this Ma Jun..." I was about to say something, then thought about it, "Let's forget it."
You have to do this yourself.
The results of the autopsy were surprising. Ma Jun did not die from poison, the substance in the needle was just water.
"If I guess correctly," Mo Zinan's voice on the phone sounded rather lazy, and he was probably sleepy, "a large amount of air should have been injected into his blood vessels, and then a gas embolism formed, and finally naturally Leading to sudden death. As for the needle... there is a luminol reaction on it, which only appears on the needle. But this is actually very strange."
"What's weird?"
Mo Zinan paused for a moment, "It stands to reason that the pain caused by death by air injection is very great, and it does not kill people in an instant. Therefore, usually the deceased will have traces of violent struggle. However, there are very few such traces on Ma Jun's body. . Secondly, for the goal of killing with an air needle...the dose of this needle is too small. The dose of one injection is completely insufficient, even doubling the dose is far from enough."
"Can I inject continuously?"
"Theoretically...Theoretically, as long as multiple injections can be completed quickly within a certain period of time to ensure that the human body cannot process this part of the air, the goal can be achieved. But there is only this one pinhole in Ma Jun's body. Even if the deceased is not considered The struggle before death can be guaranteed after several quick injections. The difficulty of operating such a perfect wound is also... very difficult. I can't say it's not possible, but at least I shouldn't be able to do it."
I straightened my thoughts and felt that this result was really strange.
"In other words, the murder weapon may not be the needle?,"
"That's right." Mo Zinan answered very simply, "Although the blood on the tip of the needle should indeed be Ma Jun's, but...at least theoretically, the size of the murder weapon does not match the actual murder weapon."
"To be precise, this water is pure water. In other words, it should have been distilled water."
This should narrow down the search for the culprit.
"In any case, as long as there is no problem with my judgment on the cause of death," Mo Zinan concluded, "then the murderer must be a professional in this field, as I said before."
"In that case, we have a suspect." Lu Bo's voice came from a distance, and he was really confident.
These words are very reassuring, but something seems wrong?
I lowered my head to confirm. The phone was still on. I did not turn it on speakerphone so that I would not be deafened, but I did not add any conference call function.
Then I glanced in the direction of Lu Bo, and I saw him taking off his headphones in a very artificial way, squinting his eyes and shaking the few raised hairs on his head, making them stand up straighter, and then tilted He rubbed his neck and squinted his eyes.
I once doubted whether our place was a regular criminal police team, and whether I was the only wise and powerful leader here.
Forget it, let’s get rid of Ying Ming Shen Wu.
What a miserable person.
----------
The suspect's residence is also an apartment. Compared with Ma Jun's two homes, it is much smaller and older. It is an old building built several decades ago. There are more than a dozen cracks in the paint on the walls. Even seams. This old house is really old, but not primitive. To put it nicely, it means everything is simple, but to put it bluntly, it has no decoration, so it is painted with a layer of white paint. However, the area where this house is located is really excellent. It is actually in the inner area of a well-known university, and the surrounding environment is also considered beautiful.
The person who received us was an old gentleman, the father of the suspect. He temporarily asked us to wait indoors until he came back. The reception was really attentive. The only thing is that this old gentleman's words and deeds are so retro, and his words are mixed with plain language, which makes me, a scumbag who seems to have learned nothing in high school, really feel a strong oppression from the inside out. feel. After asking around, I found out that this person turned out to be a professor in the literature department of the university.
The old gentleman was very talkative and very keen on the interaction between police and citizens. Just when I was about to search my head for the ancient text "Inscription on a Cottage House" to prevent it from damaging the cultural image of criminal police, our real protagonist finally appeared and saved my life.
"Ma Jun's brain is sick."
This was the first thing the current suspect said when I met him, and it was probably the most exciting thing I've heard in a while. After saying this, he just sat on the sofa, took off his glasses, and inexplicably curled up a weird smile at the corner of his mouth.
Zhang Xiaohua is just over thirty this year and is a surgeon. From the first glance, you can tell that this guy is really a very particular person. From inside to outside, from top to bottom, he can be said to be well organized. Coupled with his handsome appearance and gentle temperament, It is obviously a style that girls like nowadays. According to the information previously investigated, this person's economic level is also good. According to popular terms, this is probably the so-called diamond king.
We found him because, according to Ma Shu, he was Ma Jun's only friend who even she knew. The reason for our acquaintance is simply that Zhang Xiaohua once came to visit Ma Jun at their home, but even if it was just this, it was surprising enough to me.
It's a bit suspicious that these two people are friends. It’s not that I’m discriminating against the deceased, it’s just that the normal social circles between the two are so different that it’s hard for people to connect with them.
"It is said that you visited Ma Jun three days ago? Did he do anything unusual at that time?"
"If it's compared to usual times, then it doesn't." Zhang Xiaohua shrugged, his expression as calm as before, "Compared to normal people, he has always been very weird, and it was naturally the same back then."
"How do you know him?"
"The Internet. To be precise, it's actually an online game." Zhang Xiaohua tilted his head halfway through his sentence, paused, looked at his father, then turned back, frowned and said to me, "Yes Web game.”
Perhaps the experience just now left such a deep impression on me. When I heard such modern words, I didn't react for a while and was stunned for a long time.
"Actually, that's a coincidence." He seemed a little embarrassed, raising his hand to cover half of his face, "The specific details are very common, the only difference is that Ma Jun's words caught my attention... ...No, it's just that - judging from his words and deeds, Ma Jun doesn't look like a normal person at all. So..." He stopped mid-sentence, and he probably didn't know how to continue.
This can be said to be a very strange statement, which makes me feel inexplicably funny. Looking at Zhang Xiaohua like that, he probably felt quite embarrassed. His face was a little uneasy, and he seemed to be unable to bear it.
"that's all?"
"That's it."
Since he didn't want to say it, there was no point in dwelling on the details.
"Then do you know how Ma Jun died?"
Zhang Xiaohua's expression froze when he heard this, but he still showed doubts on his face at the right time.
"He died from a vascular embolism caused by an air needle injection."
"I see." Zhang Xiaohua tilted his head, his expression relaxed, "In other words, officer, are you doubting me?"
This guy didn't seem very excited, and seemed to take it for granted. He even picked up a porcelain cup from the coffee table next to him, took a slow sip, and raised his eyebrows, looking like he was enjoying it.
"That's right." Then I didn't need to deny it. "Then what do you think?"
"I didn't kill the person." Zhang Xiaohua said lightly, "From my point of view, this is a fact. Although I can't prove this."
"What if I could prove it?"
"Then I won't be here now. But I did not kill him, and I have no reason to kill him. Of course, I have no way to prove that what I am telling the truth, and there is no basis for you to judge me as the murderer."
I was speechless. At least in the last sentence, he was indeed telling the truth.
"But there is one thing I must explain. Yesterday, I did go to Ma Jun's home."
