"Tell me on the phone! I can't leave the hospital until Siyan comes back. Xu Tian said.

"Oh well! After the mother of the girl who was killed in the hospital confessed to the crime, I think that the same will be the case in the previous cases, and the other two cases where the victims were killed at home were also at home when the victim's parents were at home, and we ruled out the possibility that the victim's parents committed the crime because of the concept that the tiger poison does not eat children. After that, I entered the household registration system to check the family situation of the other two cases, and found that Wang Lin's family was reorganized, Wang Lin followed her mother to the city's household registration when she was seven years old, and the head of the household is now Wang Lin's nominal father, which means that Wang Lin is not her father's biological daughter at all. ”

"Is that the same for another family?"

"Something like this, do you think we're going to be looking for something wrong?"

"It's possible, but if our target was wrong from the start, then why did there happen to be a death of a broadband repairman in front of a psychiatric clinic? And the murderer is still ......," Xu Tian said, and stopped here.

"You accompany Sitong in the hospital, and I will now go to investigate the other two murders in depth."

"Wait a minute!"

"What's wrong?"

"By the way, you can investigate the situation of the murderer in the past year, such as what places he frequents, etc., and the murderer's browsing history on the Internet is the most critical."

"Good!"

"Another point, the girl who was killed at the school could please do another investigation, I think there is still a possibility that the broadband repairman committed the crime, at least the murder that happened at the school should have been done by the broadband repairman."

"I also believe in this, if the truth is true, then the murderer who killed Xiao Shuang may be Huang Quan, there are multiple murderers in a series of cases, there must be some kind of connection between them, but I don't have a clue now."

"You give me some time, and when Siyan rushes back to the hospital, I'll go back to the police station immediately."

"Then please!"

After hanging up the phone, Xu Tian sent a reminder text message to Siyan, it was already approaching evening at this time, and so many things had happened in just two days, Xu Tian felt very tired.

"You haven't slept in two nights, have you?" Sitong said.

"It seems to be! So much has happened in these two days, it feels like it's been two weeks. Xu Tian leaned against the wall and said.

"I hear it, is the case getting troublesome?"

"It's a lot of trouble, but Sitong doesn't have to worry too much, I can handle it."

"Siyan and I hid from you to cooperate with Dr. Lin before...... I'm so sorry! ”

"Why did Sitong apologize to me?"

"I ...... I don't think it should be done to you. ”

"Sitong thinks I have a mental problem?"

"Nope! I just think you've been stressed out too much lately. ”

"It's okay! This kind of pressure is actually not bad for me, Sitong, you should understand, right? ”

"But ......"

"I feel as if Sitong wants to say something to me, if there is something to say to me, I don't want Sitong to hide everything in my heart."

"Actually...... It's Dr. Lim. ”

"Dr. Lin? What's wrong with her? When Xu Tian heard Dr. Lin's three words, he immediately became very sensitive.

"Dr. Lin and I witnessed the murder of the girl upstairs today, you should know about it, right?"

"Did she say something to you?"

"I didn't say anything special, but I felt a strange feeling when I came into contact with Dr. Lin today."

"What is it?"

"I feel that Dr. Lin today is not the same as the Dr. Lin who went to our store before, and I just feel it."

"What does Sitong think is different about Dr. Lin?"

"Aside from Dr. Lin's appearance and the addition of glasses, I think Dr. Lin's breath is a little different."

"Breath? Can Sitong elaborate on that? ”

"Dr. Lin is sitting in front of my hospital bed today, and I smell a sour smell from Dr. Lin's breath, but the Dr. Lin who went to our store before gives me the feeling that he is a person with a fresh nose."

"Sitong's observation is very keen, and to be honest, I also found out about this matter."

"You found out too? So why do you think that's why? ”

"Doesn't Sitong already have an answer in his heart? Just need me to make sure, right? ”

"Unlikely, right? Aside from the snort, I didn't find anything different about Dr. Lin, and it should be unlikely that there would be two Dr. Lin. ”

"Sitong, don't make a noise about this matter first, this Dr. Lin is really weird, you must be more careful, if Dr. Lin comes to Sitong again in the future, remember not to be alone with her."

"I see!"

"By the way, when did Sitong first meet me?" Xu Tian asked casually.

"Why do you ask? Have you forgotten? The first time we met was in the village, when Brother Huang Quan and Officer Zhang accompanied you to my house. Sitong said suspiciously.

"Have we met before?"

"Probably not! What's wrong with you? Why are some strange questions asked? ”

"Nothing! I just feel a little familiar with Sitong. ”

"Hey, hey! You're too old for this routine, aren't you? Even people like me, who have been in the mountains for a long time, think it's outdated. ”

"I ...... I didn't mean that, Sitong, don't get me wrong! ”

……

At around 7 o'clock in the evening, Siyan returned to the hospital, and Siyan, who could not pretend, did not deceive Sitong, and finally confessed the truth.

"I didn't expect this to happen! What's wrong with Brother Huang Quan now? Sitong asked.

"Emotions have calmed down, but he doesn't seem to know me." Siyan said.

"Brother Huang Quan's mental condition has always been very bad, I remember that when I took Brother Huang Quan home with my mother, I met Brother Huang Quan in a hospital, and Brother Huang Quan was already receiving treatment at that time, I thought that Brother Huang Quan's condition had recovered, but I didn't expect it to be like this."

"Maybe what happened in the village caused him a stir! But I still think it's strange, why did Brother Huang Quan come here? I didn't tell Brother Huang Quan that the two of us were in this city. ”

"I haven't said it, the old village chief has told me a thousand times, and I haven't forgotten it."

"Didn't the old village chief let you tell Huang Quan where you went?" Xu Tian asked.

"Yes!" Sitong replied. "The old village chief told us so, the reason is that we are afraid that we will be dragged down, and we are not able to support Brother Huangquan now, so Siyan and I were going to earn some money and discuss it later."

Buzzing...... Lao Chen called.

"Hello? Officer Chen, is there any progress on the case? ”

"You go downstairs, I'm at the entrance of the hospital."

Xu Tian felt that Lao Chen's tone was very solemn, and after hanging up the phone, he rushed downstairs.
