The man walked down to the Toyota Senna station wagon, drummed for a while, and suddenly burst out of the car.The fire spread quickly and quickly set off.The arson man took the opportunity to run out of the yard and fled.

Song Baoguo personally found the doorkeeper in the backyard and called for questioning.

The doorman said that he had just fallen asleep, and later found that the fire was up, and then rushed out to see, and did not pay attention to whether anyone went out.

Lu Xiaotang said: "From the video, I am more convinced that the arson person is an insider, although the surveillance did not capture how he attacked Murong Yuchuan, it is obvious that he came out from the direction of the building, so it was not monitored."He also said that he deliberately wrapped himself up, there is a clear sense of avoiding the camera, only the insiders will be so familiar with the environment.

Song Baoguo shouted at the police officers around him, “ Gather all the people in the bureau!”

...

...

The fire was extinguished,

Soon, the people of the bureau gathered downstairs, and even the director arrived, looking at Song Baoguo with a heavy face.

“What happened?”Director Zhang Changlin calmly asked Song Baoguo.

“Mr. Zhang, we suspect that an insider set fire to the ground.”Song Baoguo said carefully.

"Internal arson!" director Zhang's eyebrows, "Little Song, this kind of words can't be said casually, to bear the responsibility, you know?" 」

“I know, I know...” Song Baoguo stuttered some.

Lu Xiaotang took over the words to Zhang Changlin and said, "Director Zhang, there was a series of fire in the forensic room inside the Public Security Bureau, the suspect's vehicle was burned, if such a big thing is not clear, is he not afraid to take responsibility?"Now the criminal has dared to destroy the evidence in the Public Security Bureau, and it is probably difficult for you to bear it yourself.”

Zhang Changlin's face changed, and he softened his tone: "Land team leader, this case is yours and Xiao Song, and the people of the Municipal Bureau reasonably investigated."I don’t know much about the actual situation.Or do it as you please.”

“That is nature.We must first find out the man who committed the arson.In the surveillance, we watched him escape.It is now necessary to look at who is left in the branch and to make it clear that the absence is in detail.”

"That's natural, check it out."Zhang Changlin was also not good at saying anything, and his face was on the side.

Lu Xiaotang let Song Baoguo classify the department according to the division, all those who are not present statistics, and then check one by one.Song Baoguo focused on checking those who were not in the bureau, checking several, all on vacation or on assignment.

Lu Xiaotang said at this time: "Captain Song, I have another clue here."Do you want to see it first?"

Song Baoguo rolled his eyes, “What clue?”

Lu Xiaotang took a yellow pear string wrapped in paper towels from his pocket, "This is what I just found next to the car that caught fire in the backyard, I think it is very likely that the arson people accidentally fell to the ground in a hurry."There will be sweat on the string, it is easy to check the DNA, as long as this person is inside the public security bureau, want to find him, it should not be difficult.

“If a police officer accidentally falls to the ground, it is not without that possibility.”Song Baoguo said.

"At the very least, we should look at this person first."

At this moment, a policeman raised his hand hesitantly and muttered, “I seem to have seen...”

This policeman is from the forensic doctor's office and is called Zhang Ping.

Lu Xiaotang hurriedly asked him, “Where have you seen it?”
