Solving the case: The opening scene solved a major shooting case, and the boss Ji Jie

"Xiao Song, what clues did you find?"Gu Ming asked

"Director Gu, the victim saw the murderer's clothes, which were said to be a dark green uniform. In addition, she also saw a badge on the murderer's left pocket. We took a look and it should be a work badge specially made by the factory."

Song An gave Gu Ming the badge sketch drawn by Tian Rui.

Gu Ming took it in his hand and looked at it for a few times, but couldn't figure it out, so he passed it to other people.

When it was passed to Ji Jie, Ji Jie took a look and immediately said,"This work badge seems to be from a machinery factory. What is it called?......."

"How is it, Ji Jie, can you remember it?" Gu Ming asked quickly.

""I'm sorry, Director Gu, I really can't remember! I just remember that there was a city-wide security joint defense meeting one year, and it seemed that the security department of a certain factory wore this kind of badge." Ji Jie recalled.

Gu Ming immediately ordered,"Make a thousand copies of this badge sketch, leave a few police officers on the riverside to continue patrolling, and the rest of the criminal police and police officers from the police stations in each jurisdiction will set out quickly to find the source of the badge as quickly as possible!"

After receiving the order, several team leaders set out immediately and searched for the badge overnight.

When Song An and Tian Rui were about to set off, they were stopped by Gu Ming.

"You two have made great contributions in discovering the clues, and you have been patrolling all night these days. Go back home tonight and have a good sleep. It’s not too late to investigate tomorrow!"

The director gave the order personally, and Song An did not insist. He drove Tian Rui back to the dormitory, and he went back to his rented house to rest.

Early the next morning, Song An received a call from Ji Jie. Da Zeng and Jiang Han from the sixth team had found out that the badge was custom-made by the Security Department of Xinghui Machinery Factory!

Song An put on his clothes and ran downstairs quickly. Ji Jie was leaning in front of the police Cherokee and waved at him.

"You guys are really efficient. You figured out the badge in less than one night!"

Song An sat in the car and took a bag of hot buns handed over by Ji Jie. He took a bite of the bun while talking.

Ji Jie was driving the car and said happily,"You don't know? Da Zeng has caught many pickpockets before. He has a lot of informants. These pickpockets know how many rat holes there are in this city! Not to mention such an obvious factory badge."

Song An thought it made sense. He also wanted to develop some informants, but unfortunately he had been dealing with major cases recently and didn't have the opportunity.

The Cherokee stopped in front of the Xinghui Machinery Factory. Da Zeng and Jiang Han were chatting at the factory gate. Several people greeted each other.

Song An estimated that it was about 10 kilometers from Xinghui Machinery Factory to Qingyi River, and it should take about 30 to 40 minutes to ride a bicycle.

"Da Zeng, are you sure that only the security department members are wearing it?"Song An asked directly

"It must be right! That guy used to steal from factories in this area. He had stolen from Xinghui Machinery Factory three times. He is very familiar with the situation in this factory. That badge was indeed made by the Security Department."

Da Zeng said as he took out a deposit slip and showed it to Song An.

"Look, this is the deposit slip that Shanghua Arts & Crafts Company left when they ordered this batch of badges last year."

Song An nodded,"Let's go, let's go to the security department."

Song An and his three companions went directly to the security department of the machinery factory.

A short, thin, middle-aged man with dark skin stood at the door and asked,"Excuse me, who are you looking for?"

Song An took a special look at this man. He was wearing a dark green security uniform and a wide-brimmed hat. There were obvious oil stains on his cuffs and collar.

"Chief Sun, is this you? We are from the Yanshan Criminal Police Team."

Ji Jie took out her police ID.

Chief Sun took the ID and looked at it, then quickly returned it."Hello, Chief Ji, welcome to our factory to give us guidance!"

Chief Sun invited Ji Jie and her group into the office, where five security guards were sitting. They were all wearing dark green work clothes and had identical badges on their left pockets.

""Everyone, stand up!" Chief Sun shouted.

When several security guards saw the police coming, they stood up quickly, shrank their necks, stood on tiptoe, and stood in a row.

Ji Jie found a chair and sat down, looking at the six people.

""Tell me what you were doing at 10 o'clock last night?" Ji Jie asked.

Section Chief Sun smiled and said,"Leader, this is what happened. Our factory held a winter production mobilization meeting last night. All of us in the security department went to the venue to maintain order. The meeting lasted until 12 o'clock and we had no time to leave." The five security guards nodded at the same time,"Yes, yes, we all went."

Ji Jie saw that the legs of a security guard standing in the middle were obviously trembling.

Ji Jie raised her voice and asked,"Are you sure that everyone was at the venue?"

"Wait a minute!"

Chief Sun suddenly thought for a moment, pointed at a security guard in the middle and said,"Ning Yong, it seems you left for a while last night, right?"

"Yes, yes, yes, I can testify. This guy told me he had a stomachache, but he didn't show up even after the meeting was over!" A security guard shouted

"Hehe, he's probably going into the woods with the lady from the cafeteria again.........."A security guard smiled obscenely.

Song An looked at Ning Yong. He was about 170cm tall, a little fat, with a scruffy beard, a greasy face, and a black collar on the back of his neck.

"Sun Ke, and the rest of you, don't joke about this kind of thing! It could kill people!"

The security guard named Ning Yong's face suddenly changed, and he waved his hands in panic to deny,"Officer, I swear to God, I was really at the venue at the time, and I didn't leave for a minute!"
