"Three police officers, just now I thought that Yuanyuan had an accident, and I was too stimulated and too emotional. Thank you for your understanding. Yang Xiaotian's tone softened a lot.

"It's fine. It's human nature for you to be sad, and we can understand that. You don't have to take it personally. Shen Xinyun replied indifferently.

She thought to herself, under special circumstances, it is normal for people to lose control of their emotions, and only a few strongmen with excellent psychological quality can not get out of control, Yang Xiaotian is just not a strong man, but an ordinary person.

At this time, Dai Dongjie was staring at the surveillance, and suddenly his eyes lit up, and he immediately came over to interrupt Shen Xinyun's words: "Did you check Jing Yuan's computer at the scene of the crime today?" ”

Shen Xinyun also suddenly remembered Li Yuannan's confession, glanced at Yang Xiaotian and replied in a low voice: "Not yet, or we will go now..."

Dai Dongjie raised his voice.

"Don't worry, the team has been closed today, let's go over tomorrow and look at it, by the way, let's see if there is a diary, I heard Ruan Muling say yesterday that Jing Yuan has the habit of keeping a diary, you want Jing Yuan to stay in the bureau for one more day and one night."

"Okay, Team Dai."

After Shen Xinyun agreed, he turned to Yang Xiaotian and said, "You don't go to work today?" ”

Yang Xiaotian sighed and replied; "I'm on leave, I don't have the heart to work today."

Dai Dongjie said: "Since it has nothing to do with you, don't take it too seriously, we still have a lot of things to leave first, as for your rental house, because it is a murder scene, you can't go in and live now, tonight, you either live in Aoqi or live in the Black Magic Internet Café." ”

"I asked for leave everywhere today, haven't you checked the scene, why don't you let me live home."

Li Qiran had already realized Dai Dongjie's thoughts, and said helpfully: "Jing Yuan can't live home either, please understand." ”

Yang Xiaotian had to agree.

"Let's go back to the police station first to sort out the information."

Shen Xinyun said, and before leaving, he glanced at Yang Xiaotian sympathetically, which was a farewell. She didn't expect that Jing Yuan was so bad to him, but he was still so infatuated and worried about her.

When Dai Dongjie returned to the police station, Bai Shengxue had already made the autopsy report.

The cause of Li Shasha's death was the same as that of Wang Zixiong and Li Yuannan, which was also poisoning by rat poison, and what surprised them was that Li Shasha, who was not married, was actually pregnant, and the child was already 20 days old.

Wednesday, April 21, 11:30 p.m.

In a small room with no lights on, the door lock was quickly opened.

A man in black cautiously walked in and quietly closed the door.

He didn't dare to turn on the light, but walked lightly to the window and pulled the half-curtained curtains open.

With the light coming in through the window, he walked to Jing Yuan's computer and pressed the start button.

Then he thought of something, and immediately turned on the mini flashlight prepared in advance with his mouth in his mouth, leaned on the bookshelf next to him, and skillfully threw the books from the shelves to the table, one after another, rummaging for something.

Just as he was looking for it, he only heard a "pop" and the light turned on.

The man in black was startled and turned back in a panic.

Dai Dongjie and Shen Xinyun walked over from the kitchen.

"I've been waiting for you for a long time, Yang Xiaotian, Yang Gong." Dai Dongjie's tone was full of fierceness.

For this sudden change, Yang Xiaotian immediately petrified on the spot and froze in place.

Dai Dongjie sat on the sofa slowly, straightened his tired head, stared at Yang Xiaotian and said: "During the day, I deliberately released the bait, but I didn't expect you to really come tonight, but it was a little late." ”

Shen Xinyun stood on the side, with mixed feelings in his heart.

When Dai Dongjie told her that the murderer was Yang Xiaotian and would know at night, she didn't want to believe it at all.

Yang Xiaotian looks so honest, hardworking, and infatuated, how could he be a murderer?!

After a minute, Yang Xiaotian had come to his senses.

At this time, his furrowed brows had been stretched, and his mouth was upturned, looking indifferent.

"I don't know what you're talking about? My salary card is still in this room, so I remembered it, so I came to pick it up. ”

"Yang Gong, you are much smarter than you appear, but a wise man has a thousand thoughts, there must be a mistake, maybe you can't help it, you know that it is very risky, but you must come! If you came to pick up your pay card, you could have come generously during the day, or could you get it directly from the police? ”

"yes, why sneak around?" Shen Xinyun also asked him disappointedly.

"I, I was too frightened, I didn't think about it so much for a while......" Yang Xiaotian tried to quibble.

"Needless to say. I'll help you out. ”

Dai Dongjie interrupted him sharply.

"During the day, I deliberately mentioned keywords such as mobile phones, computers, and notebooks in the Internet café, and you suddenly remembered that when you were poisoned last night, you forgot that something was here, and you were afraid that we would find it, so you must take it away in advance, so that you can rest assured, but this thing is not the bank card you said, but the clues you accidentally left when you committed the crime."

Yang Xiaotian began to panic, but pretended to be calm: "It's not my poisonous rat strong." ”

Shen Xinyun picked up the recorder and said, "The autopsy report of Li Yuannan and Li Shasha has never been released to the public, how did you know the ingredients of the poison?" With that, he pressed the "Playback" button.

"It's not my poisonous rat power." The sound was not loud, but it was enough to make Yang Xiaotian's scalp numb, and his eardrum was almost shattered.

"Here's what you're looking for."

Dai Dongjie said, picking up a small plastic bag in his right hand, which contained a piece of paper that had been folded a few times.

"This contract, we will do a fingerprint test when we go back, and I will see what else you can say when the time comes."

Yang Xiaotian suddenly looked like a deflated ball, and instantly despaired.

He suddenly remembered something, and his eyes glowed with a thief's grin.

When he spoke, he was immediately full of confidence.

"This contract was checked and put at home by me, it is precisely because of this contract that I know that Wang Zixiong and Li Yuannan died of rat poison, I was just unlucky, and I checked things that should not be checked, just based on these, you can't conclude that the murderer is me, I have an alibi!"

Dai Dongjie smiled: "Alibi, what a professional word, I usually watch a lot of reasoning novels and reasoning movies?" I'm guessing you've seen Agatha Christie's Murder on the Orient Express, right? ”

Yang Xiaotian pulled the bitter gourd face and became silent again.

Dai Dongjie really lived up to his reputation, and he actually knew his modus operandi.

"In the afternoon, we have investigated very clearly, and your other four roommates have also confessed that your dorm five people have stolen spare parts from the factory to the dormitory. After you have finished assembling in the dormitory, you will go down directly from the balcony window with a sack and a long rope, and one person will answer below. More than 500 air conditioners a year. That's a lot of money! Of course, all the monitoring is done by you, and for you as a veteran hacker, this is not a problem, and your roommate even showed us the hemp rope and bag. ”

"Hacker, I didn't even go to college." Yang Xiaotian's head couldn't help but lower a little.
