"Where did the murderer get so much body fat?" Reilly asked the right question, where could he get so much body fat and use it as fuel.

"If it's beef fat, you can go to a butcher's shop, but if it's human fat. The officer paused visibly.

"Maybe it's a morgue, I don't know very well. ”

"We are doing DNA testing on the samples. Han Weixue next to him said.

"We think it's a homicide. Wang Lei expressed the views of him and Han Weixue.

"Why?"

"There was no evidence of ignition found at the scene, so the murderers who set fire to them must have had fuel with them, the same substance that burned through the door locks, and the door locks for the loading and unloading ports. Wang Lei gave Reilly his analysis.

"We have also found similar cases of theft in abandoned or closed premises. ”

"Stealing copper is nothing new, have you ever visited a scrap yard?" "Stealing copper is all too common for Reilly, after all, copper is a valuable thing, and it is needed in many places.

"Yes, they said they didn't receive any copper. Wang Lei also has some questions about his investigation, why didn't this thief sell?

So that thieves don't just steal and don't sell? Reilly also felt a bit of a headache in this case.

"Papapa" turned out to be Zhang Yusheng knocking on the door.

"Sorry to bother, but there was a witness who said he saw someone run away from that building last night. ”

"I was driving through there last night, but before I saw the news, I had no idea that two people had died there. Sitting opposite Han Weixue and Wang Lei was the driver last night, he saw the news today, and he thought that the person he almost hit last night was the suspect.

"Did you see someone outside the building?" asked Wang Lei, and Han Weixue wandered around.

"Yes, he suddenly rushed in front of my car and I almost hit him, I don't know if he had anything to do with the case, but he was there and he looked terrified. He recalled the scene of last night, and there were not many good citizens like him.

"Can you describe his appearance?" asked Han Weixue.

"I'll never forget it, half of his face was scarred, his hair was unkempt, he looked like he hadn't been washed in a while, he was wearing a long trench coat, I guess he was a vagabond. He pointed to half of his face and described the man's appearance.

"What happened when you parked the car?"

"I yelled at him and called him an idiot, but he ran away without looking back. ”

"Didn't you see him get in the car?"

"Nope. He thought about it, shook his head and said.

"We'd like you to describe his features to the sketcher and see if you can make a portrait of him. Wang Lei looked at the question and continued to ask, he would definitely not be able to ask anything, whether this person had anything to do with the case, and now he couldn't get a conclusion, so he could only wait for a portrait first, and then find this person, whether it would be very clear.

The owner of the scrapyard bought a new lock and relocked the outside door, and as soon as he turned around, he found that there was a person standing behind him, and he was the homeless man, who was holding a steel rod in his hand, and knocked him unconscious with a single blow.

In the police station, the appearance of the homeless man was soon drawn in the hands of professionals, although it was drawn orally, but it was still very close to the real person, and the witness sat aside and looked at the painting in her hand and nodded and said, "It is already very similar." Han Weixue and Wang Lei, who were on the side, heard it and came over and looked at the painting in the painter's hand, which may be of great help to their case.

"Hey, someone just called the police and found out that the owner of the house that was stolen was attacked outside the fire, and a patrol car happened to pass by. Zhang Yusheng hurriedly came to the two of them and said.

The boss had been helped by the patrolling police to sit on top of the police car, his head had been broken, the blood had not yet dried, and it didn't look serious.

"An ambulance is needed here at the scene of the fire. The patrol officer shouted into the switchboard.

"He attacked me. The boss saw Han Weixue and Wang Lei coming and complained to them.

"I guess he's still in the building. ”

"Stay with him. Han Weixue said to the police next to him, and he and Wang Lei were ready to enter the building.

"He ran back to the crime scene by himself?" Wang Lei didn't expect such a stupid thief.

"If you see him, don't approach him, keep an eye on him, and let everyone know. Han Weixue and Wang Lei walked towards the factory, and he ordered the others to guard the door.

Han Weixue and Wang Lei quickly entered the building, because this person may be the murderer who killed those two people, so Han Weixue and Wang Lei were also very vigilant, they took out their guns and searched slowly.

When they were halfway there, they stopped, because they heard a "rustling" sound coming from inside, and there must have been someone inside, and the two of them raised their guns again and walked inside one after the other. Zhang Yusheng took two police officers to the other side, and they were also cautious.

Han Weixue and they quickly walked to the place where the two people were burned to death, the bodies had been cleaned up, only the marks on the wall remained, Han Weixue shone it with a flashlight, and nothing was found in this corner, they turned a corner, and Han Weixue stopped.

He whispered in Wang Lei's ear: "The shopping cart is gone." ”

"How did they get it?" Wang Lei was a little puzzled.

"The elevator is broken, the only thing is the stairs. ”

"There's movement upstairs. Someone on Wang Lei's walkie-talkie said.

After Han Weixue and Wang Lei heard it, they hurried to Zhang Yusheng's place. Zhang Yusheng walked in front of him a little nervously, after all, he rarely faced such a dangerous place directly, and suddenly he stopped, as if he heard something.

"I heard a voice. He said into the intercom.

"In the logistics pick-up area. Several police officers around Zhang Yusheng have begun to search separately, so he is now alone, Han Weixue and Wang Lei are rushing in his direction, but this place is too dark, who knows how many people are on the other side, so the speed of the two of them is still very slow.

At this time, Zhang Yusheng seemed to have encountered some gas, and it was like water vapor, but it was not a state of vaporization, this kind of thing was permeated in the air, and Zhang Yusheng had been surrounded, and some had entered his nose and eyes, he closed his eyes and coughed violently, and it was already very difficult to breathe.

"I've been sprayed by the fog and can't breathe!" Zhang Yusheng immediately called for help into the walkie-talkie.

"Stand back, run, don't shoot!" Han Weixue said into the walkie-talkie, and the two of them ran towards Zhang Yusheng's quickly.
