Chapter 217 Police Officer's Suspect
"Why on earth did he do this?"
The 'he' in his words, of course, refers to Xiao Xia, who untied the rope of the corpse and committed two crimes.
He pondered Xiao Xia's motives. Of course it couldn't be that she was just doing good deeds every day. It seemed that the other party just regarded this as fun.
It can be seen that he is not a normal person, and his psychological quality is even far beyond that of ordinary serial killers. He can actually do things like sinking into the river to untie the ropes on the dead body.
His criminal profile may be more detailed, and from this incident we can know that he is good at drinking.
"He thought it was interesting. In my opinion, he is a person who believes that works should be exhibited. So unlike most people who subconsciously hide their work after committing a crime, he did not cover it up and felt that he should not cover it up. Perhaps it was this psychological drive that made him display the body in front of people in his own way after seeing the murder case at 603."
Lin Zhi could even feel his excitement from the gifts he gave her.
This may be a criminal with an antisocial personality, whose cognition is different from that of ordinary people.
The young man sitting in the passenger seat had an expression that was calm, almost indifferent, as he calmly analyzed the murderer's thoughts, like an analyst or examiner who was not involved in the matter, without any personal emotions involved. Or rather, he did not have any personal emotions at all.
He didn't think it was terrible that the murderer did these things, even though he was also in the game.
Qiu was a little dazed and stepped on the brakes suddenly when he saw the red light, and his body suddenly leaned forward due to inertia.
Lin Zhi sat back down and said jokingly, "It seems that next time we should not talk about these things while driving, lest you become obsessed with them."
The young man was joking, and his pretty eyes and brows were filled with a playful smile, making him look more lively.
The indescribable emotion in Qiu Huo's heart suddenly disappeared. He looked at the seconds of the red light and said, "I didn't notice it because I was missing him. Give me your phone."
Lin Zhi was a little confused, but he still took out the phone from his pocket, unlocked it and handed it to Qiu Huo.
Qiu Huo quickly saved a short number in it, stepped on the accelerator when the green light appeared, and returned the phone to Lin Zhi.
"This is my other number. When I'm on a mission, the other number will be muted or at most set to vibrate. This number won't be muted. If you encounter an emergency, calling this number is faster than calling the police."
Of course, Qiu may not want Lin Zhi to be of use, but he always has to be prepared for the worst.
When Qiu Huo said this, he didn't look at Lin Zhi, he was concentrating on the road conditions.
There was no light in the car, and the scenery outside passed by quickly, making his face appear bright and dark.
He didn't say any sweet words, but they carried more weight.
Human emotions are extremely strange. Sometimes the word "love" is so light that you can casually express it to a stranger, and sometimes it is extremely tactful, and you would rather use thousands of words to expand it than express it out loud.
The structure has long been stable, and the words that will not be easily deformed or changed carry emotions, the amount of which is up to the person.
"Then I'll set it as an emergency contact."
Lin Zhi held the phone with smiling eyes and immediately set the number.
He could have enjoyed this love with peace of mind long ago without having to worry about giving anything in return.
For some people, accepting love from the bottom of their hearts is more difficult than loving someone, but time can erode everything, whether it is glacial rocks or thick walls of the heart.
Qiu Huo responded, and there was no emotion in his voice, but the corners of his mouth could not help but rise, and he was obviously very satisfied.
Lin Zhi took in his expression, and the smile in his eyes grew brighter, like a flower that had absorbed enough nutrients and was becoming more vibrant.
Lin Zhi talked about the gift he received today. Qiu Huo raised his eyebrows and asked, "Why didn't you tell me earlier?"
He stepped on the accelerator and sped up his way back to Lin Zhi's house.
The opened small gift box was still neatly placed on the coffee table, with the note lightly pressed by the box.
Lin Zhi: "I wore gloves when I touched it, but there may be fingerprints of the delivery person on the box. You can take it away and have it tested."
Qiu Huo nodded, looking at the marks on the paper and also at the bill.
There was no need to check the surveillance footage from Cinema No. 14 that day. A week had passed and the surveillance footage was likely covered. Plus, given the murderer's caution, Qiu might not think he would show up in person to buy tickets. Besides, the workload was too huge and there was no need to waste time on it.
Qiu Huo called his colleagues in the laboratory and asked them to come and work overtime.
After backing up your stuff, send the person downstairs.
"It's been a hard night."
Even if Qiu Huo knew that checking fingerprints might not produce any results, it would still take more effort than checking the cinema surveillance, so he had to do it even if it produced no results.
The colleague from the laboratory nodded, opened the car door, and waved at Qiu Huo.
Before he started his car, he saw Captain Qiu walking towards the apartment.
There seemed to be something wrong with this natural movement, yet there also seemed to be nothing wrong.
When Qiu Huo returned to the apartment, Lin Zhi was taking a shower in the guest bathroom.
There was a sound of dripping water. Qiu Huo stood in front of the balcony, looking at the building opposite in the dim light. He had asked someone to register the house that could see Lin Zhi's home. This was a big project. As long as one had the heart and the equipment, one could look down from above.
Not everyone is at home to cooperate with the registration. The murderer hiding in the crowd is like a fish in a school of fish.
Qiu Huo pulled the curtains on the balcony, opened the door and went into the bathroom.
The guest bathroom does not have a bathtub. It adopts a dry and wet separation design, and semi-frosted glass isolates the space.
Qiu Huo took off his clothes and opened the glass door.
The shower space, which was already small, became even more crowded with the entry of the man. The air seemed to be squeezed and condensed, gradually heating up.
Qiu Huo is tall, with full and smooth muscle lines that are not exaggerated, and exudes a sense of power.
This is not a beautiful appearance. There are scars of various sizes scattered on it. The most hideous one is below the navel, near the mermaid line, which adds a bit of dangerous yet calm and reliable charm to him.
Qiu Huo took the bath ball from Lin Zhi's hand and volunteered to wash his back.
The sticky shower gel created plenty of foam on the bath flower, and Lin Zhi leaned against the wall. Qiu Huo even considerately placed one hand on Lin Zhi's forehead to prevent him from hitting his head.
"I've bought the tickets. Let's go to the movies tomorrow."
Lin Zhi's voice was soft as if it was stained by water mist, and a little hoarse because it was lowered.
The foam always makes me rub against it intentionally or unintentionally when squeezing it. Compared with the time in front of the sink, it feels a little more tight, giving me the illusion of being invaded at any time.
Even though he knew that Lin Zhi said this because of the movie ticket sent by the murderer, this invitation that was like a date still made Qiu Huo's heart skip a beat.
"good."
Qiu Huo leaned on Lin Zhi's shoulder and hugged him from behind, as intimate as a pair of mandarin ducks.
More than twenty minutes later, Lin Zhi was hugged by Qiu Huo and walked out of the bathroom.
Qiu Huo's way of holding people is very interesting. He doesn't hold Lin Zhi like a princess, but holds her in his arms as if she were a child.
Lin Zhi leaned lazily on his chest, closed his eyes drowsily, and let Qiu Huo wipe his hair.
It was almost midnight. Because he had been taking medicine and maintaining a stable schedule these past few days, Lin Zhi had already become sleepy out of habit before taking his medicine today.
When Qiu Huo had almost dried his hair, he discovered that the young man was almost asleep.
Qiu Huo didn't move, planning to wait until Lin Zhi fell asleep before moving out of the living room.
The phone vibrated with a message, and Qiu Huo hugged Lin Zhi and looked at the message.
There were fingerprints on the gift box and on the movie ticket inside. The two fingerprints belonged to two different people. There were no fingerprints on the printed paper. It was very clean.
The fingerprint was searched in the database but no matching data was found, which was within Qiu Huo's expectations.
He sent a message to his colleague saying thank you for your hard work, clicked into the gallery and enlarged the details of the image of the printed paper.
Unlike the words on paper, the three vertical lines are handwritten.
However, even the most skilled and experienced handwriting identification experts cannot tell anything from these three vertical lines.
After staring at it for a while, Qiu Huo felt that these three vertical lines might not be the pattern they had previously identified.
This doesn't look like an inverted triangle, the distance in the middle is too narrow, it looks more like some kind of mark or symbol.
And if it was an inverted triangle, it would be inconvenient for the murderer to scratch the body, so couldn't he draw it on paper?
"What are you looking at? You're looking so intently."
When the voice came, Qiu Huo realized that Lin Zhi in his arms had opened her eyes at some point and was looking at him sleepily.
Qiu Huo placed the phone sideways in front of him and said, "This, I don't think it's an inverted triangle, it's more like..."
"because."
Lin Zhi's voice was sleepy as she took over Qiu Huo's words.
He became suspicious when he saw the signature and made a judgment after analysis.
"The symbol 'because' in mathematics is usually represented by a dot, but when writing, it may not be possible to use a standard dot. Many people can use a short vertical line to express the same meaning."
In addition, when a knife pierces a person's body, it is also a flat line. If you want to use a long round spike as a weapon, it is relatively rare and troublesome.
"This symbol is more common in middle and high schools, and is usually used in preliminary geometric analysis. It may be used to infer that the murderer's education level is not high, because this symbol basically does not appear in college. It cannot represent other mathematical logic, and it is not a formal logical deduction symbol."
In Lin Zhi's memory, '∴' is used more frequently than '∵', but it has basically not been seen since high school. Mathematics is a very rigorous subject. In many formal writings, these two symbols are not considered, and there is no debate about its rationality. There is a consensus in the field of mathematics that these two simple symbols can only be used in geometric proofs.
The murderer used this as a representation of himself, which means that this symbol has special meaning to him, but this kind of knowledge is basically not deliberately remembered after leaving high school. However, this is only an inference and may be very different from what you really think.
The young man was particularly charming when he spoke these inferences lazily. Qiu Huo lowered his head and looked at him straight, and when the man finished speaking, he leaned over and kissed him.
The young man's lips were warm and soft, and there seemed to be a tempting sweet fragrance hidden between his lips and teeth.
After a brief taste, it was still not enough. When Lin Zhi, who was kissing him, was completely unable to get up from his arms, Qiu Huo let him go and continued to say: "Your calculation makes sense."
In fact, the police also believe that the murderer may not be very old. If he was an adult with a mature appearance, the second victim would probably not have gone to help him without any precautions.
However, young age and low education are not completely the same. If we can really judge that the murderer has a low level of education, combined with the murderer's understanding of the city, we can outline a simple identity profile. The other party may be a school dropout and a migrant worker, but there are so many such people in Ru Ning.
