The private car turned around and drove back to the hotel.

Jiang Yi hurried into the lobby to go to the restaurant. Sun Lai and the others were still in the private room, but the door of the private room was open, and the waiter was inside. He handed over the bill after checkout to Sun Lai, who casually threw the bill on the table.

"Sun Lai."

Hearing the sound, Sun Lai raised his head and was slightly surprised to see Jiang Yi coming in from the door.

The waiter handed in the form here and left the private room. Others here looked at Jiang Yi and Sun Lai for some unknown reason, thinking it was some uncle Sun Lai knew.

Sun Lai didn't stand up.

Jiang Yi walked in front of Sun Lai, and within a few short steps, he could feel a slight change in Sun Lai's expression, from surprise to calm, a little nervousness appeared in the calm, and the movement of his fingers on the armrest also changed.Slightly tightened.

"Why are you here? Also eating here?" Sun Lai asked.

"Yeah, I happened to be eating here. It seemed that I heard the voice was you, so I just happened to come over to have a look. I just wanted to ask you something about your mother."

Sun Lai frowned inadvertently, and a fleeting reluctance flashed across his face, showing a sad look at random.

"What's wrong with his mother? Who are you?" The only girl present interrupted. She stood beside Sun Lai and looked at Jiang Yi warily, her tone a bit aggressive.

This age is no longer a child.

Jiang Yi said seriously: "I'm a forensic doctor, and it's about work, so I want to ask a few more questions."

"Forensic doctor?" Another boy blurted out, with an excited and suspicious expression, "The kind that dissects corpses in TV dramas."

Jiang Yi: "Yes."

The expressions of the other students ranged from surprise to bewilderment, and someone immediately thought of the question, "Since you are a forensic doctor, then... Sun Lai, did something happen to your family? Or your mother..." The man behind the wordsThe classmate didn't go on, fearing that it would be unlucky, but everyone understood what it meant.

Sun Lai's expression changed again, and he gave them a cold look, "Our family has nothing to do with you."

The girl was still in a daze, "Why don't you tell me something about your family?"

Sun Lai: "It's just a dead person, there's nothing to say."

After the words fell, thinking of something, he raised his head and met Jiang Yi's eyes, and then he was startled.

Jiang Yi was also surprised. Sun Lai was too indifferent towards his mother's death, but on the day of the murder and the day he came to the hospital to look for him, it was clearly not the case.

"Doctor Jiang has something to talk to me about, you guys go first, I'll come later." Sun Lai said to the other students.

Several classmates responded a few times, got up and left the private room one after another, the girl hesitated, and after being comforted by Sun Lai's eyes, she picked up the bag hanging on the back of the chair. Although Jiang Yi didn't pay attention to big names, it was a coincidence that the girlHis bag was of the same brand as one of his wallets, and his wallet was bought for him by Xu Xian, and the lowest price was 70,000 to 80,000 yuan, let alone a bag.

Because of his professional relationship, he likes to find out the details. Except for the bag, the girl's other clothes are ordinary. It seems that the bag should be given by someone else.

She is Sun Lai's girlfriend, so is it hard to guess who might give her a bag?

"I'll wait for you outside the hotel," the girl said.

"Well," Sun Lai nodded.

The girl helped them close the door. Seeing another man at the door, she couldn't help but look into the private room a few more times, even though she couldn't see the inside anymore.

Jiang Yi said sorry, pulled away the chair next to Sun Lai and sat down, "I don't know if your classmates don't know, I just want to ask you, how did you get the syringe that day, and where did you find it at home?"

Sun Lai said without thinking, "In my grandma's room."

"So you think your grandma took the syringe?"

"In her room, of course she took it."

"Do you turn on the heat in your house in winter?"

This question made Sun Lai feel a little inexplicable, but he still answered honestly, "Yes, what's the matter?"

"How many clothes do you usually wear at home?"

"One piece. If you turn on the heater to the maximum, you can wear short sleeves."

"So you don't wear gloves at home, do you?"

Sun Lai was stunned, his body was a little stiff, his eyes glanced to the side unnaturally, his eyes had nowhere to rest, he just fell on the bill, and said: "My hands are prone to frostbite, and I often wear gloves at home."

"Oh, like this."

Jiang Yi followed his gaze and glanced at him casually, not knowing if he didn't look, and he was startled when he saw it.

A few students came to the hotel restaurant to eat, and it cost more than 13,000?

Sun Lai noticed that Jiang Yi was also looking at the bill, so he reached out and took the bill, seemingly unintentionally playing with it, folding it in half and then in half.

Jiang Yi didn't hide from him, and deliberately teased: "You guys ate more than 13,000 in one meal? What delicacies are you ordering?"

"Is this related to my mother?" Sun Lai asked.

Jiang Yi was more direct: "Did you pay for it?"

"What's the problem if I paid for it?"

"As far as I know, your father is an ordinary office worker. His monthly salary can't cover your meal expenses. And your mother passed away. Who gave you the pocket money?"

"Isn't it okay that I saved it before?"

"After saving so much, you bought your girlfriend a bag worth hundreds of thousands?"

After asking this question, Sun Lai's face was pale and pale, and he was a little blocked for a while. He and the girl just confirmed that the boyfriend and girlfriend were yesterday, so they came out to celebrate today, and the bag was just bought in the morning.Understand how Jiang Yi knew it so quickly?

Or.....

Suddenly, a slight grunt sounded in the quiet space.

It's a WeChat message.

Sun Lai took it out and took a look at the first time, and the content was displayed in the message prompt on the screen.

He lowered his head, Jiang Yi couldn't see the change in his eyes, then raised his head, denying it flatly, "She bought her bag herself, how can I have hundreds of thousands to buy such an expensive bag, Doctor Jiang, I drinkI drank too much, I want to go to the bathroom and come back."

"Okay, let's go."

Sun Lai got up and left.

Xu Xian leaned against the door, folded his hands on his chest, and said, "How is your question?"

Jiang Yi's face was a little dark: "I think the doubts on him are getting bigger and bigger."

"How to say?"

Just as Jiang Yi was about to analyze, Xiao Shao called him, "There is an update on the case, do you want to hear it?"

"I do not want to hear."

"what?"

"It's strange, you hurry up and say it."

"You are too out of breath," Xiao Shao said, "Team Zhou came to the hospital again just now, and I happened to meet him in the infusion room. It turned out that Li Meiying came to the hospital to fetch water on the day of the incident. It was her son.He came with him, Team Zhou came to check the medical records of the day, and Li Meiying's mother-in-law should not be the murderer. Now her son Sun Lai is the most suspected, but you said that he can really do such a cruel thing at a young age, killing himselfMother?"

Jiang Yi listened, and glanced at the tableware on the table that the waiter hadn't had time to clean up, leftover meals, unfinished champagne, red wine...

Just no drinks.

Oops!

"Xiao Shao, contact Team Zhou immediately and ask him to bring someone to the Boya Hotel on Weihe Road. Sun Lai is here, and he is the real murderer!"

Jiang Yi rushed out of the private room while talking, and Xu Xian followed closely.

Pushing away the nearest men's restroom, knocking on every cubicle, Sun Lai was really not in there, it was a fake to go to the restroom, and he had already run away!

Jiang Yi chased him out of the hotel.

Sun Lai hurried into a taxi.

Jiang Yi pulled Xu Xian and ran to the parking place, "Hurry up, help me catch up with the taxi in front of me. If I let him run away today, I think he will hide in the future."

"it is good!"

Xu Xian got into the car immediately, Jiang Yi pulled the co-driver and sat in, Xu Xian put into gear, stepped on the accelerator, and turned the direction.drive out.

There were not many vehicles on the road at noon, Xu Xian quickly caught up with the taxi, and followed closely behind. Jiang Yi felt a little more confident, and contacted Team Zhou on WeChat to initiate location sharing.

Xu Xiandao: "You said that Sun Lai was the murderer?"

"I think so," Jiang Yi said his analysis, "Sun Lai is too suspicious. He gave me an insulin syringe before, and the residual liquid in it was not insulin but organic phosphorus. I thought it was too deliberate.And it is even more strange that there is no fingerprint on the syringe. Even if you wear gloves when you go out, you will also wear gloves when you get the syringe at home. This syringe must have the fingerprints of at least three people to be reasonable, he, his mother and his grandma.”

"So he knew from the beginning what was in the syringe, and in order to avoid suspicion, he didn't leave a trace of fingerprints on his body."

"Yes, he also knows that his grandma will cover him up and deliberately lead the evidence to point to his grandma as a scapegoat, but he didn't expect it to show his flaws, and why didn't he say that he went to the hospital with Li Meiying that day? I guess it was when he was in the hospitalHe did something to cause his mother to die in the hotel, and the organophosphate poisoning is just a confuse."

While Jiang Yi was talking, he kept staring at the vehicle in front of him, "I suspect that the money he spent so generously was not saved by himself, and it must have something to do with his mother's death."

At this time, Team Zhou called.

Sirens also sounded outside the car window, and three police cars came from the meeting lane, just in time to stop the taxi.

Jiang Yi was concise and neat, and reported the license plate number to the phone.

The driver of the car ahead slammed on the brakes. Before he could figure out what was going on, he heard a sound from the back seat, and the boy who was sitting in the car opened the door and ran away.

The doors of the three police cars also opened immediately, and they quickly chased after Sun Lai, and knocked him to the ground within a few steps. Sun Lai yelled, "Why are you arresting me? I didn't kill my mother! I didn't kill anyone!"

"Why did you run away if you didn't kill someone!" Team Zhou shouted.

"You don't care what I run, why catch me!" Sun Lai was hysterical, struggling desperately, his eyes were almost crazy.

But obviously, his denial is not convincing.

Team Zhou signaled, and two police officers pulled him up and took him into the car.

Jiang Yi wants to follow, Xu Xian grabs him with a big hand, hugs his waist tightly, and reminds Jiang Yi in a low voice, "You are a forensic doctor, and interrogation is not within your scope of duty. Now, it's time to buy what I want."It's gone."

"What are you talking about? I don't understand," Jiang Yi picked out his ears, playing a rogue.

Xu Xian slowly curled his lips, "It doesn't matter if you don't understand, everything will be fine if you put on a pose at home."

Boom!

Jiang Yi punched out.
