Before he returned, Xie Chuchu had already verified the DNA from the excrement. However, after searching the database, no suitable samples were found, indicating the killer had no prior record. Of course, these things might not have belonged to the killer.
We compared several corpses but found no match.
If that thing didn't come from the killer, could there have been someone else in the house?
It's too complicated. I first found Xiao Yuande and took him to the forensic department. While examining the camera and repeater from this case, He Xin patted my shoulder and said, "Dad, I don't know why, but my stomach hurts!"
"Are you sick again?"
Mentioning illness made me worry she might catch a cold like last time.
However, He Xin said, "I haven't eaten breakfast for days!"
"Really, you know you have a stomachache, yet you're not careful!" I immediately bought her a soy milk and fried dough sticks. After eating, He Xin's condition slightly improved, and she continued to help us examine the data.
However, after a long struggle, He Xin said, "It's no use. It seems the data has been tampered with. It can't be restored at all. The files have been deleted, and I can't retrieve them!"
I looked at Yuan Hezhe, who immediately spread his hands and said, "Don't look at me like that. I'm just He Xin's apprentice."
"If we can't see it this time, is it because the killer's movements were captured? He was afraid of being exposed, so he deleted it?" Xiao Yuande guessed.
"We still don't know how the killer entered the villa," I said, hinting at something. Gao Mingqiang quickly understood, "Team Leader He, if you don't believe me, you can go out and check the villa again. We've investigated several times and haven't found any basements or underground passages."
I patted Gao Mingqiang's shoulder, "I didn't say I didn't believe you." I thought even if he couldn't find anything, how could Xiao Yuande miss it.
Of course, I wouldn't say that to Gao Mingqiang, or he'd be upset again.
Suddenly, I had an idea and asked He Xin, "Are the cameras and repeaters this time the same type as the last ones?"
"Yes, exactly the same. This kind of equipment can be bought anywhere online. Don't think about investigating in this direction, it's very difficult!"
My faint hope was immediately extinguished by He Xin.
But what she said was true. She finished the last few sips of soy milk, wiped her hands, and said, "Let's expand the investigation scope and visit people at She Hongyuan's company. See who he's been in contact with recently."
"Liu Yuning has already gone to handle it. She'll probably be overwhelmed these days."
"I'm busy too. All my attention is focused on the computer."
"Everyone is busy, but even so, we are all working towards the same goal: solving this case."
I encouraged them and temporarily returned to my office. That's right, I planned to slack off and let others handle things for a while. Don't say He Xin, I seem to be feeling unwell lately. I haven't been sick in a long time. For a while, I even forgot that people could get sick!
Around 2 PM the next afternoon, I started feeling feverish and chilled, shivering uncontrollably, and sneezing incessantly.
Noticing my condition, Xie Chuchu specifically brought me some cold medicine to my office. Seeing the white packaging on the table, I curiously asked, "Chuchu, I don't dare to take the cold medicine you prescribed!"
"Heh, do you think I prescribe medicine for dead people? I'm a forensic doctor, I understand basic medical knowledge!"
"Is that so? Then I'll try it!"
"You can still joke, which proves your condition isn't too serious. But to prevent it from developing into a severe cold, I suggest you go home and rest for a day or two!"
I gave a wry smile, took the medicine, and then slumped on the desk. Xie Chuchu shook her head and left without bothering me. I don't know how long I slept, but my head felt heavy and dizzy. It wasn't until someone woke me up that I realized Liu Yuning had returned. At that moment, my body felt much better.
"Did you check She Hongyuan's company?" I asked as soon as I opened my eyes.
Liu Yuning said, "His company has no problems. Both his income and his relationships at the company are good. Moreover, he has no competitors. I think the killer chose him for entirely different reasons!"
"Combining the first family, haven't you noticed that their conditions were good, and they also had a son, with four people living together, right?"
"That's right. Are you saying the killer was like that before?"
"He must have experienced something similar in his childhood, but it ultimately led to tragedy, so he particularly hates such families. If I'm not mistaken, that old woman and the man probably have unspeakable secrets."
"No way? Is he not her biological son? Even so, how would a normal man be willing to be with someone younger than him..."
Before Liu Yuning could finish, I interrupted her, "Where are you going with this? Unspeakable secrets are not limited to just that kind of relationship!"
"So, should we still investigate this?"
"Of course, let's try. There are too few clues at the scene. The killer was extremely cautious and had already scouted the location. He prepared his tools before going. He definitely thought about how to commit the crime and how to escape. Such a person is very careful, and it's very difficult for us to find any traces."
As I spoke, I yawned. Liu Yuning came closer and punched my shoulder, "What's wrong with you lately? You always seem so tired!"
"I don't know. Wasn't I sick before? I probably haven't fully recovered yet!"
"Sigh, you've worked yourself to exhaustion. I told you before, this job isn't easy!"
"I understand. Isn't it because you're in the criminal investigation team? Without my help, you'd probably still be struggling with many cases."
"You're too confident, as if I can't do without you!"
I deliberately squeezed her waist hard, and she didn't resist. For some reason, she closed her eyes and waited quietly.
What is this expression? She doesn't think I want to kiss her, does she? I carefully tapped her forehead, "Wake up, it's time to work!"
"What was I doing just now?"
"You weren't doing anything, your face is just red. Have you never been hugged by a boy?"
"Uh, I haven't been hugged by a boy, but I have hugged a boy!"
"Who did you hug?"
"I'm not telling you!"
