Quan Jue asked the police to take pictures of cigarette butts. After collecting evidence, he looked up and looked up.

There are six floors in the unit building. Only the windows on the fourth floor are open. Although the light is on, no one stands at the window to watch.

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

At this time, as soon as Quan Jue looked over, all of them hid in and did not dare to look again.

"Collect cigarette ends and do DNA identification. Maybe this time we'll find witnesses. " Quan Jue's voice fell down, took back her eyes and strode in the direction of Chi Jiao.

"Officer Huo, who lives on the fourth floor of this building?" Quan Jue quickly walks over and looks at Huo Chen.

Huo Chen immediately looked down at the information and answered Quan Jue's question: "it's a man named Jiang Dashan, 42 years old, living alone."

"Does he smoke?" Quan Jue asked.

Quan Jue's question caught Huo Shen off guard. He looked at the data and shook his head: "it's not shown on the data. But I can go and find out for you. "

"Don't ask, I know! Jiang Dashan is an old smoker. He can smoke at least two packs of cigarettes a day. " At this time, a middle-aged uncle in a security suit suddenly poked his head in.

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

"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 praising Chi Jiao: "yes. I found the body first. Poor thing, a beautiful little girl just died. "

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

Uncle security shook his head and said sorry, "I didn't see it. I was so scared at that time that I went to get someone to come

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

At this time, uncle security 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, it should be visible. "

"Just now, I found a cigarette end not far from Cao Mei's body. If there is no accident, it should be Jiang Dashan. " Quan Jue then added.

"In that case, we have the first witness." Di Ziyan was so excited that he lifted his lips and said with a smile, "this is good news. Does Jiang Dashan live on the fourth floor? I'm going up to him. "

"I'll go with you." With that, Huo Shen and di Ziyan go around Cao Mei's body and head upstairs.

"Is the body evidence complete? What is the cause of death? " Chi Jiao looks at Huo Chen's men and Xiao Liu asks.

Xiao Liu was nauseous by the strong smell of blood at the scene. After two subconscious retches, he said: "the cause of death of the dead is that he was pierced through his heart. The modus operandi is similar to that of the last case. This time, however, the murderer's action was more savage. Cao Mei's chest wound showed a terrible tear... "

"I saw a wound on Cao Mei's arm just now. What kind of wound is that? " Chi Jiao has just observed the wound. She knows what the wound is like.
