forensic hunter

Luo Jianan recognized Zhou Hao in the crowd at a glance.He is so conspicuous that passengers who pass by him turn their heads frequently.Despite the exhaustion and anxiety written on his face, the flaws are not concealed.Luo Jianan believed that if Pan An was really as good-looking as the book said, he would have to grow into Zhou Hao to be worthy of his name forever.

Miao Hong, who came with him to pick him up, also looked straight at him, and after a moment of distraction, he realized that he dragged Luo Jianan towards the exit to meet him.

"Luo Jianan and Miao Hong from the Serious Crime Team." Luo Jianan showed Zhou Hao his police badge.

"Zhou Hao." Zhou Hao clasped his mouth and coughed vigorously, his voice was very hoarse, "Excuse me, can you take me to the hospital first?"

Luo Jianan made a gesture of please, and then he noticed that Zhou Hao was just dragging a small black Samsonite suitcase, which was in stark contrast to the luggage carts pushed by other passengers coming out of the international airport. contrast.

Xu Canghai has been transferred to the general ward of the Department of Gastroenterology. There is a room for two people, and the other bed is empty.Zhou Hao stood at the door and called out "Professor" softly, his eyes turned red instantly when they met each other.Luo Jianan and Miao Hong were waiting in the corridor. About an hour later, Zhou Hao came out of the room with his eyes swollen.

"What do you want to know?" he asked.

Luo Jianan narrowed his eyes slightly and said, "Everything about that bastard."

--------

"My professor and I originally planned to go to Las Vegas to get married after I graduated."

On the way back to the game, Zhou Hao squinted in the back seat, and now his voice sounds much better. "But after that happened, I didn't know how to face him, so I had to quit my job as a teaching assistant. I didn't dare to go back to live in that room, so I moved out."

Luo Jianan said while taking notes: "You said earlier that the person who attacked you sent you an email in advance. Please provide that email address. I will ask the technical department to trace the sender's IP address."

"It's useless, I've tracked it down, and it was sent through a proxy server." Zhou Hao shook his head, "My undergraduate major is information engineering, and my postgraduate major is in satellite communication technology."

"From your professional point of view, that person is proficient in computers?"

"At least he has a certain foundation, and his English should be good. Most of the proxy server providers are overseas."

"So, besides the video, did he write anything else in the email?"

Zhou Hao's black and thick eyelashes trembled, and his white teeth were deeply embedded in his lips.He took out an ultra-thin notebook from his luggage, opened it, entered his email address, and handed the computer to Luo Jianan.

"See for yourself."

Luo Jianan frowned as soon as he read the beginning—the foul language was so unsightly that even a stingy master like him couldn't say it.

Seeing the attachment at the bottom of the email, Luo Jianan said with a little embarrassment: "That... I have to watch the video."

Zhou Hao's face turned pale suddenly, he closed his eyes, clasped his fingers, took a few deep breaths and stood up. "I'll wait outside, call me after you finish reading."

The video was about half an hour long, but Luo Jianan fast-forwarded it in less than 3 minutes and finished it.It's so exciting, it's killing me.The purpose of watching the video is to prove whether the installation position of the camera at that time is consistent with what he found, and the result is yes.When Zhou Hao sat down in the reception room again, Luo Jianan returned the computer to him.

--------

The atmosphere was a bit awkward, Luo Jianan got up and got Zhou Hao another glass of water, sat down and rubbed his hands and asked, "You didn't call the police because you were worried that the video would be made public and insult Professor Xu's reputation, I understand that, but when that bastard attacked you , why don't you call for help?"

"My mouth is gagged." Zhou Hao shook his head in pain, "At first I thought he just wanted money and didn't want to make matters worse, but I didn't expect... Officer Luo, he has the key to my dormitory , I locked the door, and when he opened the door with the key, I was sleepy, and I thought it was my roommate who came back..."

"Where did your roommate go that night?" Luo Jianan asked.

"I went to watch a night movie with my girlfriend. He goes there every Friday night. He watched it all night long, because there are... couple seats in the movie theater."

Luo Jianan raised his eyebrows slightly - the police academy dormitory cannot stay out at night, he really doesn't know much about the colorful world outside the dormitory.

"So, the person who attacked you not only knows you, but also has your dormitory key, and even your roommate's living habits." Luo Jianan slightly lowered his voice, "Do you think, among the people you know, who can have this at the same time? Three o'clock?"

Zhou Hao frowned, and after thinking for a long time, he said, "I can't think of anyone other than Professor Xu, but that's definitely not him...that person...he...short and small..."

The last words were barely audible.

Luo Jianan bit the inside of her lips tightly to hold back her smile.Don't, this is in front of witnesses, after he catches someone, he will take a good hit on that messy self-esteem.But these clues are not enough, you can't pick people's pants one by one to get evidence.As brutal as it is to ask the victim to recall the experience of the attack, he still has to dig deeper: "Think about it again, is there anything else that makes you feel special?"

Zhou Hao closed his eyes, bit his lips tightly and twitched his brows, falling back into painful memories.Suddenly, he opened his eyes and said, "The smell of chalk, his fingers smell of chalk!"

Luo Jianan recorded it immediately. "The chalk the professors use to write on the blackboard?"

Zhou Hao nodded at first, but then shook his head immediately: "Professors hardly write on the blackboard anymore, they just use projectors or computers directly. If they must write, most of them are copied on the blackboard by the teaching assistants in advance, and... I I don’t think there is a professor who smells of chalk in the middle of the night, the fine powder of chalk hurts his hands, if he used chalk in class, he must wash his hands immediately after class.”

As for the memory of chalk, Luo Jianan is basically still at the stage of falling asleep in class and being thrown by the professor with a chalk tip.He struggled to recall places in school where chalk and blackboards would appear—classrooms, cafeterias, dormitories.

dormitory!

He stood up abruptly, startling Zhou Hao.

"Lv Yuanqiao!" Luo Jianan pulled open the door of the reception room and yelled at the office opposite, "Apply for a search warrant!"

--------

When the building manager saw the search warrant raised in front of his eyes, everyone was dumbfounded, shaking like when he was questioned by Luo Jianan on the day of the crime.

Combining familiarity with the living habits of the students, having the dormitory door key, understanding the maintenance process of the air conditioner, and the need to write school notices on the small blackboard at the door with chalk, Luo Jianan made a judgment-the suspect should be the building manager.In addition, Tong Yu, who was stabbed by a toothbrush before, also asked a suspicious point, that is, the time of appearance of the building manager's statement did not match the memory of the witnesses. He was enough to run within 2 minutes after pushing Jiang Xin's body out of the window. Go down to the fifth floor.The scene was so chaotic, no one would pay special attention to whether he was really the first to appear.

but……

Luo Jianan stared at Lou Guan who was not half as thick as himself.Although Jiang Xin was thin, he weighed more than a hundred catties. He was deadly, and it was not easy to drag the corpse to the waist-high window.Zhou Hao is nearly 1.8 meters tall, and he must be strong enough to easily subdue him.But the management of this building is over 60, not to mention dealing with corpses to subdue the victim, whether it can be hardened is still a problem.

"Officer Luo."

Xiao Huang handed him a biscuit box with rust on the iron sheet, which was found in a box under the bed.Taking out the "Green Ghost" from the box, Luo Jianan turned over the back of the dial, and saw the words "JX" engraved on it—Jiang Xin's initials.

That's right, it's him.

Luo Jianan waved to Lu Yuanqiao.

"Cuff and take away."

--------

Illuminated by the high-wattage desk lamp on the interrogation table, Lou Guan's old face wrinkled into a chrysanthemum.Luo Jianan interrogated, Lu Yuanqiao took notes and worked overtime, but no one complained.Luo Jianan has asked Qi Ming to go back first, he will probably stay all night tonight.

"Grandpa, it's fine, you are really old-hearted." Luo Jianan put his shoulders on the building manager's shoulders, and put pressure on him with body language, "You can also play computer games and run proxy servers, and I heard that your English is still very good , teach me, I want to climb over the wall and go out to watch a movie."

Lou Guan swallowed his saliva vigorously, shaking all over his body.He got the stolen goods at the same time, and now he has a long mouth all over his body and can't tell.Seeing that Lou Guan was frowning and not speaking, Luo Jianan stretched out his hand and turned the desk lamp to the side, so that the other party could at least open his eyes.

"Excuse me? Then tell me, what do you want to do with this watch?" Luo Jianan moved his buttocks and sat on the corner of the table, holding the evidence bag containing the "green ghost" and dangling in front of the building supervisor.

"No...not...I took it..." The building manager said tremblingly, "I didn't...I don't know..."

"Bang!"

Lu Yuanqiao slammed the table, not to mention the building management, even Luo Jianan was almost frightened and sat down on the ground.He turned his head and stared at his junior brother, with an ugly face of "You should have said hello in advance".Lu Yuanqiao continued to take notes with his eyes downcast as if he had nothing to do with himself.He just wanted to scare the old man, don't pretend to be confused when you come here!

Hey, still young.Luo Jianan was thinking that he would have to teach the younger brother a lesson later, it's okay for you to frighten someone who is ten or forty, but this is more than six cards, if he really got a heart attack, he would have to be punished.

"You can see, my little brother is impatient." Luo Jianan stepped down from the donkey - Lu Yuanqiao was so frightened by the building management that he didn't dare to shake, "Old man, please speak slowly, remember what to say What. There are your fingerprints on this watch. If you say you don’t know, I’ll go to bed. My junior brother is on duty tonight, so you can talk to him.”

"It's really not me... I didn't do anything... I just... I just picked up such a watch..." The building manager swallowed dryly, "I clean... clean the toilet on the fifth floor... see... see the corner If there is... just... just pick it up... and don't dare... dare not sell it..."

Luo Jianan shook his head. "Old man, let's talk about it when we make it round. That building was almost scraped off by our forensics department. So many pairs of eyes didn't see the small six-digit thing, so you are so dazed?"

"I... I really... I didn't..." The building manager blushed red and white, sweat rolled down his face, "Please... I didn't... Look at my age... no What are you doing to make such a fuss alive!"

Luo Jianan crossed his arms and said with a sneer, "I'm also puzzled. You said that you are still climbing onto young people at your age. This time you have to take a lot of medicine, right?"

The building manager's face would turn red. If he hadn't been handcuffed to the chair, he would have jumped up, and he would suddenly speak quickly: "Who did I climb? My wife has been dead for 20 years! After that, I didn't even You girls haven’t even touched your hands! It’s fine if you frame me as a murderer, why do you want to slander my reputation!?”

Faced with the sudden outburst of resentment from the building management, Luo Jianan raised his eyebrows and looked at Lu Yuanqiao.This old man is really funny, he said that he was a murderer, and that he was in a hurry to crawl.

At this moment, there was a knock on the door of the interrogation room. Lu Yuanqiao looked sideways, and there was Gao Ren's baby face outside the small window on the door.

--------

"Urgently did a DNA comparison." Gao Ren sniffled and handed the report to Luo Jianan.

"You have a cold?" Lu Yuanqiao touched his forehead with the back of his hand, "You don't have a fever, have you taken your medicine?"

Gao Ren raised his hand to cover his forehead just touched by Lu Yuanqiao, and said with a smile: "It's okay, it's just that I haven't been getting enough sleep a few days ago, and my resistance is a little low, and I'll be fine after drinking an effervescent tablet and sleeping. "

"I'll drive you home when I'm done with work." Lu Yuanqiao found himself in a better mood when he saw Gao Ren's smiling face.

"Hey, don't flirt here." Luo Jianan frowned and pointed at the report, "Are you sure the things in the toilet cubicle weren't left by the old man in the room?"

"No." Gao Ren swears, he has tested the samples that are taller than him before, and he is already too proficient, "However, this old man is related to the suspect. Judging from the Y chromosome, they should It's uncle and nephew."

Luo Jianan nodded. "Okay, Gao Ren, you can get off work, you have to stay, junior brother, and continue the interrogation."

"Wait for a while." Before entering the room, Lu Yuanqiao whispered to Gao Ren.

Luo Jianan snapped the report in front of the building management, and raised his chin at him: "Yes, old man, I apologize, you are innocent, and the last question, where is your nephew?"

The old man's face turned from red to white: "My nephew?"

"Yes, your nephew." Luo Jianan spread out the report to him, but he guessed that the old man couldn't understand it, "This thing is like a paternity test. It has been tested that the murderer who killed Jiang Xin is your nephew."

"My nephew...nephew..."

The old man rolled his eyes, and fell right in front of Luo Jianan.
