Quan Jue asked the police to come over and take pictures of the cigarette butts, and then after collecting evidence, he looked upstairs.

There are six floors in the apartment building, and only four of the windows are open, and although the lights are on, no one stands at the windows to watch.

Although the lights were on in the rooms of other people's houses, the people in the room were curious, but they didn't dare to open the windows to watch the excitement, and they all stood behind the windows.

At this time, as soon as Quan Jue looked over, these people all hid in and didn't dare to look at it again.

"Collect the cigarette butts and do a DNA test. Perhaps, this time we will be able to find eyewitnesses. Quan Jue's voice fell, he retracted his gaze, and strode in the direction of Chi Jiao.

"Officer Huo, who lives on the fourth floor of this building?" Quan Jue walked over quickly, looked at Huo Shen and asked.

Huo Shen immediately lowered his head and looked at the information, then answered Quan Jue's question: "It is a man named Jiang Dashan, forty-two years old, living alone. ”

"Does he smoke?" Quan Jue asked.

Quan Jue's question caught Huo Shen off guard, he shook his head after looking at the information: "It is not shown on the information." However, I can go and inquire for you. ”

"No need to ask, I know! Jiang Dashan is an old smoker, and he can smoke at least two packs of cigarettes a day. At this time, a middle-aged uncle in a security uniform suddenly poked his head out and interjected.

Everyone's eyes were attracted by the middle-aged uncle at the same time, and they glanced at the middle-aged uncle at the same time.

"Uncle, are you the security guard of this community?" Chi Jiao asked the middle-aged uncle with a smile.

The middle-aged uncle nodded, and couldn't help but praise Chi Jiao: "Yes." This body is the first thing I found. Poor ah, a little girl like a flower died like this. ”

"Uncle, when you found the body, did you see the appearance of the prisoner?" Huo Shen asked.

The security guard shook his head and said apologetically, "I didn't see it." I was so frightened that I went and called someone. ”

After the security uncle said this, everyone's faces looked a little depressed.

At this time, the security guard cleared his throat and said, "However, although I didn't see it, Jiang Dashan should have seen it." When I came, I saw him standing at the window. From his point of view, he should be able to see it. ”

"Just now I found a cigarette butt not far from Cao Mei's corpse. If nothing else, it should be left by Jiang Dashan. Quan Jue added.

"In that case, we have the first witness." Di Ziyan was so excited that he curled the corners of his lips and said with a happy smile, "This is good news, does Jiang Dashan live on the fourth floor?" I'll go up to him. ”

"I'll go with you." After speaking, Huo Shen and Di Ziyan bypassed Cao Mei's corpse and walked upstairs.

"Is the deposition of the body complete? What is the cause of death? Chi Jiao looked at Huo Shen's subordinates, and Xiao Jin asked.

Xiao Jin was so smoked by the strong smell of blood at the scene that he wanted to vomit, and subconsciously retched twice and said: "The cause of death of the deceased was death through the heart." The modus operandi is similar to the previous one. It's just that this time the murderer's actions are even more savage. Cao Mei's chest wound showed an extremely horrific laceration wound......"

"I just saw that Cao Mei also has a wound on her arm. What kind of wound is that? Chi Jiao had observed the wound just now, and she knew what the wound was in its proper state.
