After inquiring about Wang Daochuan, Qi Yuan and the others walked to Xun Mu's side, intending to report to him.

Before he could speak, Liu Xun from the Graphic Investigation Department ran over and said, "Team Xun, the surveillance video has been discovered." ”

"Oh?" Xun Mu looked up at him and asked, "What do you say?" ”

"The surveillance captured that about fifteen minutes before the deceased's poisoning reaction occurred, the deceased got up and left, presumably to go to the toilet." Liu Xun said: "At this time, the man sitting next to her is the ...... who was burned by the hot pot."

Qi Yuan couldn't help but interject and said, "His name is Sun Weitian." ”

Several people glanced at him.

He craned his neck and said nothing.

Liu Xun nodded lightly and said, "Sun Weitian picked up the cup and stood up, shouted to everyone to cheer, and then reached out to cover the deceased's wine glass while everyone was looking up to pour wine. ”

"Huh?" Xun Mu frowned and asked, "Did you read that right?" ”

"That's right, the location of the deceased happened to be vacant, and the surveillance shot was clear."

"That's weird." Brother Song answered: "We just asked the deceased's friends and learned that Sun Weitian and the deceased had been in love, and it seems that they have never been able to let go of this relationship. In this way, he does have a motive to poison and be emotionally entangled.

But if he poisoned someone, it stands to reason that he should be as low-key as possible after poisoning, how could he do something to splash that child with a hot pot? In this way, no matter whether we suspect him or not, he will have to go to jail if he spills out the hot pot soup. ”

"It's a contradiction." Xun Mu nodded, acknowledging Brother Song's judgment and said, "Except for anger, he shouldn't have the motive to deliberately hurt that child." But, since he voted for the poison, what is his anger? ”

Qi Yuan thought for a few seconds and asked, "Could it be that he just pressed the deceased's cup and didn't do such a thing as poisoning?" ”

"Hmm." Xun Mu bowed, looked at Liu Xun again, and asked, "After Sun Weitian pressed the deceased's cup, is there anything more in the quilt?" ”

"I haven't seen it yet." Liu Xun shook his head and said: "The monitoring clarity in the store is not very high, so the small cup is really not clear, go back and ask my colleagues to help and see if you can make a clear treatment." ”

Brother Song turned his head to look at the direction of the toilet and asked, "The deceased went to the toilet, could it be poisoned in the toilet?" ”

"I'll tell Lao Yan to go to the toilet and investigate." Xun Mu nodded, and then said with a strange expression: "But in the toilet...... No one eats in it, right?

Cyanide can also be poisoned by inhalation, but if this were the case, it is unlikely that there would be only one deceased person in the toilet, and more than ...... poisoned."

"What about contact poisoning?" Qi Yuan said: "The professor focused on cyanide poisoning, saying that it is relatively common in poisoning cases, and the mortality rate is extremely high, so he is very impressed, if it is cyanide, it can be absorbed through the skin." ”

Xun Mu's eyelids drooped slightly, thought for a moment, shook his head and said, "No." If it was contact poisoning, it wouldn't have died so quickly. It is one thing to be able to absorb through the skin, but it is another thing to be able to absorb efficiently, unless the exposure time is too long, otherwise the absorbed dose will not cause lightning death. ”

"Could it be vomiting?" Brother Song also said: "Drink too much, it's normal to go to the toilet and vomit, and you also need water to rinse your mouth after spitting, will it be ...... at this time?"

Liu Xun said: "But at that time, except for the deceased, no one went to the toilet at that table." ”

"What if it's an indiscriminate killing?" Qi Yuan blurted out.

The faces of several people changed instantly.

Indiscriminate homicide means that there is no way to start from the victim's interpersonal relationship and screen out the range of suspects.

Without pertinence, the investigation is naturally like a headless fly, and the difficulty of solving the case has risen sharply.

Moreover, the perpetrators of such cases are often quite dangerous, and if they cannot be caught as soon as possible, they may commit crimes again.

Fortunately, Brother Song stabilized the mood of the diners before, and left their names, addresses, and phone numbers, which roughly ranged.

Thinking of this, Liu Xun immediately said: "I'm going to rummage through the several surveillance cameras that can be photographed at the door of the toilet, and screen out all the people who have entered the toilet before and after the deceased." ”

"Hmm." Xun Mu bowed his head lightly, and said: "This is just a guess, the possibility should not be great, I think the perpetrator is still hidden among the companions of the deceased, it is better to focus on this piece."

Xiao Liu, before the deceased was poisoned, was it only Sun Weitian who touched her things? ”

"Well, only Sun Weitian has covered her cup, and no one else has touched it."

"Go to someone," Xun Mu said, "go to the hospital and ask Sun Weitian if there are any signs of cyanide poisoning, and do a blood test."

If he did poison, it should have been a powder or pill, and according to his method, the finger slap would always have to come into contact with the drug, and a small amount of the drug might penetrate into his body through the skin. ”

"I'll go." Qi Yuan said: "By the way, find a doctor to change the medicine." ”

As he spoke, he couldn't help but smile bitterly.

I thought that my niece was abducted and trafficked in the past, and I could recover from my injuries, but I didn't expect that I could eat a murder case when I came out to eat a hot pot at night.

"It's fine." Xun Mu glanced at him, nodded, looked at Brother Song again, and said, "Song, you can send someone to be with Xiao Qi." ”

"No, no, I can do it." Qi Yuan said: "This injury is not a problem. ”

The corners of Xun Mu's mouth twitched: "But you don't have the right to enforce the law." ”

Qi Yuan: Embarrassed

……

Brother Song couldn't leave for a while, so he sent an old criminal policeman to go to the hospital with Qi Yuan.

Well, the old criminal police and the criminal police are two concepts, he is actually still young, but he is about thirty years old.

But......

Qi Yuan found that he didn't even know him.

After scratching his head in embarrassment, Qi Yuan asked, "Senior, that, what do you call it?" ”

"My name is Fang Chang, you can call me Lao Fang or Brother Fang." He was quite talkative, and said with a smile: "I heard Brother Song talk about you, saying that you are a good seedling, and maybe I will have to ask you to take care of you in the future." ”

"Ahem, it's just commercial blowing, Brother Fang, don't care." Qi Yuan's skin was not thick enough, and he felt even more embarrassed.

is also because Brother Song brags that he blows too much, and he doesn't dare to deal with other seniors now.

Nine times out of ten, he will say "I heard Brother Song talk about you", and he is also very helpless, not to mention that some of them are just joking, but some people are sour when they say it......

The hospital that Sun Wei added was not far from Yida Plaza, and the two chatted awkwardly for a while.

Fang Chang parked the car and said, "I'll go and ask about the situation, you can directly register and ask the doctor to help you change the dressing, the injury is serious, hurry up and talk about it." It's hot now, and it's troublesome to get inflamed. ”

"It's okay," Qi Yuan didn't pretend to be polite, nodded and said, "Then Brother Fang, give me a number, I'll go to you." ”
