Half an hour later, Lao Chen led the police to the scene of the crime, and the preliminary investigation showed that Xiao Shuang was killed by a dagger similar to a flying knife, and the murder weapon was found behind the audience.

However, the entrance of the stage was about two hundred meters away from the landing point of the flying knife, and it was hard to imagine that the flying knife could be thrown so far with artificial strength, and the flying knife also cut Xiao Shuang's throat in the air.

Siyan and Sitong had already gone home, and Xu Tian didn't want to care about it, but when he saw Lao Chen walking into the gymnasium, Xu Tian took it upon himself to follow in.

"There is nothing strange about this case, it's just that the strength of the throwing knife is suspicious, normal people definitely don't have that much strength, I feel like this case is like martial arts!" Lao Chen said.

"I won't participate in this kind of physics problem, is there a fingerprint detected on the flying knife?" Xu Tian asked.

"There is a small cool fingerprint, and the fingerprints have not been superimposed, and there are no traces of scratching." Lao Chen said.

"That means that when the flying knife was thrown into the air, it was caught by Xiao Shuang, or ......"

"Or maybe Xiao Shuang cut his throat by himself."

"There are only two possibilities, but I think suicide is less likely, right?"

"I think so too."

"You're wrong." The swallow came over and said. "It's possible that this scheming woman could commit suicide."

"Why do you say that?" Xu Tian asked.

"I've been staring at her for a long time, Xiao Shuang met with two girls of the same age three days ago, and one of the girls died at home that night, and this matter has been on the local news, don't you police know?" Swallow said.

"The case from three days ago?" Xu Tian looked at Lao Chen questioningly.

Lao Chen glanced at him, and Xu Tian understood at that time that everyone was preparing to go to the cat mansion three days ago, and the case should have been taken over by other policemen.

"I've heard about that case, and someone from the sub-bureau took over the investigation." Lao Chen said.

"What kind of case is that? Can you tell me more about that? Xu Tian asked.

"I've only heard about it, and I haven't seen the case file yet. The deceased was a twenty-one-year-old junior girl, one foot was tied with a rope, and her body was hung upside down on the balcony of her house. The murder weapon was not a flying knife, but an ordinary blade, the kind of blade found in a disposable razor. ”

"It's so similar, have the people from the sub-bureau solved the case?"

"No, because there are too many mysteries at the scene, and the deceased's background is somewhat special, and the case is being prepared to be handed over to us."

"Who is it?"

"The daughter of a college professor."

"What's so special about this?"

"Because that professor also holds an important position, you can understand that, right?"

"Got it! So it's important to solve the case as soon as possible, right? ”

"The people from the sub-bureau are sorting out the case files, and it is estimated that they will be delivered tonight, but this incident happened here again, don't think about sleeping tonight!" Lao Chen smiled bitterly.

"Your name is Swallow, isn't it?" Xu Tian asked. "Can you elaborate on your findings?"

"What? Do you want to solve a case? Swallow said with a calm face.

"Are you prejudiced against me?" Xu Tian said.

"There is no prejudice, but you have to remember what I said to you, you better not wander around, where there is you, there is death, don't you find it yourself?"

"I don't know why you've rejected me, but there have been homicides in places where I haven't been, and your claims are baseless."

"Say whatever you want, but my prediction will not be wrong."

"The biggest suspect in killing Xiao Shuang is you, if you don't cooperate, I don't need to say where you will spend tonight, right?"

"Humph!" The swallow gently raised the corners of its mouth. "I don't know the exact reason, but I can tell you where the girl who walked with Xiao Shuang with another deceased person three days ago is."

"Where?" Lao Chen hurriedly asked.

The swallow pretended to be deep, closed her eyes and pinched her fingers, like a fortune teller on the street.

"To the south, not far from here, walking down the street, they are walking in groups, and if they drive at this time, they may be able to catch up." Swallow opened her eyes and said.

"What the hell are you playing? Tell us if you know! Xu Tian said.

"It's the girl who talked to you when you were in line today." Swallow said.

"Which one?"

"Dressed in civilian clothes."

"Bai Qi?"

Xu Tian got into the police car with Lao Chen, because only Xu Tian knew what Bai Qi looked like, and sure enough, he saw Bai Qi walking on the street two kilometers away, and there were three other girls walking with Bai Qi.

"That swallow said it so accurately!" Lao Chen muttered to himself.

"It must have been Yanzi who heard Bai Qi say where to go at the end of the performance, if it wasn't too far, the four of them would definitely walk, and the means were not clever at all." Xu Tian said.

"But I still think it's a little strange, why does the swallow know so well?"

"This is also very simple, by asking the circus people, you can see that Yanzi and Xiao Shuang are rivals, I speculate that Yanzi must be secretly investigating Xiao Shuang these days, she must be trying to find negative evidence of Xiao Shuang, so that Xiao Shuang can be completely excluded. However, Bai Qi and the girl who was killed three days ago had contact with Xiao Shuang, and Yanzi naturally investigated them, if they could find out what they had done badly, they could completely suppress Xiao Shuang. Xu Tian analyzed.

"I really don't understand these little girls of the same age!" Lao Chen smiled bitterly.

Lao Chen parked the police car on the side of the road, and walked directly to Bai Qi after getting out of the car with Xu Tian, when Bai Qi saw Xu Tian, his face showed a very surprised expression, and at that moment, Xu Tian obviously felt a trace of horror in Bai Qi's eyes.

"Xu Tian? What are you doing here? Bai Qi said in surprise.

"You know Xiao Shuang, right? It's the girl who performs the trapeze artist on stage. Xu Tian said.

"I ...... You don't suspect that I killed someone, do you? Bai Qi said calmly.

"There is no such thing." Lao Chen said. "But we found some clues, you met Xiao Shuang three days ago, and there was another girl with you, do you admit it?"

"That's the thing." Bai Qi lowered his head, his eyes obviously a little flustered.

"Can you give us the contact information for the other girl?" Xu Tian asked.

She ...... She's dead, are you testing my tone? Bai Qi said.

"Come with us!" Lao Chen opened the car door and said.
