Criminal Investigation Notes

Sand does not appear out of thin air. Every grain of sand has been processed, and then in the hands of bombers, it is then placed in those bombs.

The police contacted the sand factory that produced the sand, and the factory was very cooperative and provided all the production and sales data for their inquiry.They also specially dispatched a salesperson who lives in Huadu to come to the general office for inspection.

After testing, the sand was indeed produced by the sand factory in Xin County, and peacock blue was the latest color that was produced this year.

And the wholesalers who bought these sands were narrowed down to a few.

In addition to cross-comparing with other colors of sand and explosion time, after a day and night of intense investigation, the scope was narrowed down to six institutions.

The fine sand has been using these sands as a personal mark, and he probably didn't expect that it was these very common colored sands that exposed his whereabouts in the end.

Lu Junchi divided the serious crime team and the previous special case team into several groups, and began to investigate those businesses one by one, registering everyone who might have come into contact with the sand.

The scope of the list gradually narrowed, and finally more than a hundred people were screened out.

Su Hui looked at the list, and a name named Lan An caught his attention. This is a 27-year-old young lady who runs a special sand bottle painting workshop.

It is special, because the workers in this sand bottle painting workshop are all special people, they are some disabled people with mild autism or disabilities.

Their job is to fill sand bottles in the workshop day after day.

"There is something wrong with this list. No matter how small a painting workshop is, it is impossible for only four people to have access to these sands." Su Hui said to Lu Junchi, "I want to go here to check."

Lu Junchi nodded: "Okay, I'll prepare here right away, bring a few criminal policemen, and go with you."

This sand painting workshop is located in an alley in the suburbs of Huacheng, and it is a bit difficult to find. Lu Junchi parked his car outside and entered with Su Hui.

The sand bottle painting workshop is not big, only more than 100 square meters in total. The left side is the place for painting, and the right side has a partition. Various raw materials are stacked behind the partition. There are several shelves at the back of the room, on which are finished products. sand bottle.

At the side front of the house, facing the street, there is a floor-to-ceiling window with some of the most exquisite sand bottles.

The female boss, Lan An, looks very young and beautiful, and she is very gentle when she speaks: "This place has been in operation for more than a year, in order to provide these children with a place to work..."

Lu Junchi checked over there, and Su Hui leaned on his cane and observed the small and crude sand bottle studio in front of him.

There are several tables in the studio, with various sand bottles and colored sand on the tables, and several young people are drawing sand bottle paintings at their desks.They were silent and focused, paying no attention to these visitors.

Inevitably, a lot of fine sand fell on the floor of the room.

"I see that there are already eight people here. Why aren't their names listed in the register?" Lu Junchi asked.

"Some of them are disabled, and some are young, so some omissions were made in the previous registration list..." Lan An showed a trace of embarrassment on his face, "Well, Mr. Police, you don't think these children will be Criminals... Many of them can't take care of themselves at all, and it's even more impossible for them to go out to wander around. Coming here from home every day is considered a long trip to them. Moreover, they are all good and simple-minded children..."

Some of those children cannot go to school, and they may be underage after calculation. The employment here is not standardized.

Lu Junchi said: "I'm not suspicious of them, but we are currently investigating a case. The list you handed over will affect the police's judgment, so I hope Miss Lan will register truthfully."

"Okay..." Lan An pulled her hair and took the registration form, "I will write each of them on the form."

"Including their home address, mobile phone information, etc." Lu Junchi urged.

Lan An hummed, took out a pen, and began to fill in the information booklets left in the past.

"Are you married?" Lu Junchi looked at the woman and asked her suddenly.

In her form, she did not write her relatives. If she runs this sand painting workshop here, her family will also have the opportunity to come into contact with the sand.

Lan An paused her pen, raised her head and said, "My parents are both dead, and I'm not married. I've always been alone... That's why I opened this sand bottle painting workshop here."

"Are all the children here disabled?"

"Some of them are Asperger's patients." Lan An explained.

"Asperger's?" Lu Junchi heard this word for the first time.

"Asperger's symptoms are similar to autism, but the symptoms are relatively mild. This disease and autism are both diagnosed as ASD..." Lan An lowered his head and continued to fill in, "Children with the disease have poor language skills. The big movements are uncoordinated, and some words will be repeated, but it does not affect life too much. It is generally difficult to integrate into society with autism, but Asperger’s is different. If you train for a long time, children can communicate with people simply , to work, to be self-reliant."

Lan An simply finished writing the information about those people, and Lu Junchi took the paper and faced them one by one.

He wants to make sure that the names of people and people can be matched one by one.

"Are there many children in this situation in the studio?"

"This is the case with the boy named Dong Yuchen and the girl named Xu Sha."

"Which one is Dong Yuchen?"

Lan An pointed.

Lu Junchi looked along her hand, it was a boy who looked very clean, he lowered his head, focusing on the sand bottle in his hand.The boy was between a teenager and a young man, about 20 years old, if Lan An hadn't told him about his situation, Lu Junchi could hardly tell that the boy in front of him was a patient.

"Where's Xu Sha?"

Lan An pointed it out to him again.

Lu Junchi said, "I want to ask them some questions."

Lan An clapped his hands, and said to them as if coaxing children: "Uncle policemen came to see you drawing today, and they may ask you some questions later, don't be nervous, answer whatever you know."

Lu Junchi started to ask the workers questions, but Lan An was free, and she walked to Su Hui's side.

Su Hui stared at the window, where there were many completed sand bottle works.

Many sand bottle paintings are very simple, that is, layers of colored sand overlap, and some sand bottle paintings are very complex and exquisite.

"Do you like sand bottle painting too?" Lan An asked Su Hui, opened the door and handed him a sand bottle.

"Exquisite works of art, who doesn't like it?" Su Hui looked down at the sand bottle in his hand, then pointed to several sand bottles inside and asked, "Whose works are these?"

Even if his eyesight is poor, he can tell that the paintings in those sand bottles are very complicated and the colors are very beautiful.

Lan An sorted out the sand bottles with her slender fingers, and replied, "Those are painted by Yu Keke. She has a high artistic talent, and many customers will buy the sand bottles drawn by her."

"Is she here now?" Su Hui asked.

Lan An shook her head, showing a regretful expression: "She hasn't come here to work recently."

"Why didn't you come?"

"Probably because it's inconvenient to come here. Our place is a bit remote. She told me that she wanted to draw it at home and send it over."

"When did she not come?"

"About a month ago." Lan An replied casually, "I also registered her name on the record sheet."

Lu Junchi asked those young people a few questions, and also heard about Yu Keke. He pointed to a group photo of young people on the wall of the studio: "Is Yu Keke this girl?"

Lan An nodded: "Yes, her feet are congenitally deformed, and it's inconvenient to go out. After doing it here for a while, I won't do it."

"How did she come to work in the past?" Lu Junchi asked.

"It was her parents who sent her here..." Lan An said.

"She comes here by bus every day..." A girl at the side raised her head and interrupted suddenly.

Lu Junchi remembered that she was the girl named Xu Sha.

The whole studio fell silent, and the air froze for a moment.

Lan An was a little embarrassed: "That may be because I didn't pay attention sometimes..."

"Does any of you know which bus she took?" Lu Junchi asked again.

Some of these children were mentally immature, and some had physical disabilities. They all looked up at Lu Junchi, hesitating whether to speak.

"Bus 78," said a boy at last.

Lu Junchi and Su Hui glanced at each other. Bus No. 78 is within Duan Siyuan's range of activities.Nothing excites a beast more than a handsome, shy, immobile prey who cannot resist.

Lu Junchi knelt down and asked the girl, "Has Yu Keke mentioned to you that some strange things happened on the bus..."

Xu Sha, who had spoken to him before, suddenly became a little afraid to speak. She turned her head subconsciously, trying to find Lan An.

Lan An was about to walk over when Su Hui reached out and grabbed her.

Lu Junchi squatted down in front of the girl: "It's okay, you tell the police brother, we will help her."

Then the girl faltered and whispered: "She said that there was a man who always bullied her in the car..."

As soon as this sentence came out, the other teenagers also started to say it.

"Well, it's because there are bad people, that's why Yu Keke doesn't come to work here."

"If the bad guy disappears, she'll come back..."

"That bad guy deserves to die."

In the sand painting workshop, there was a soft sound suddenly, someone accidentally knocked over a sand bottle, and some colored sand fell to the ground.

Everything is finally connected, the colored fine sand, the molester on the bus.

Lu Junchi looked at the young people in front of him. Most of them were around 20 years old, some of them were mentally retarded, and their expressions didn't change much when discussing issues.

This sand painting workshop was indeed related to the fine sand case. Lu Junchi got up and walked decisively to the criminal police who came with them, and discussed with them a few words.

Then he turned to Lan An and said: "Now all the personnel here need to be transferred, the workshop is temporarily closed, everyone here needs to be further interrogated, and the workshop also needs to be searched. All of your communication equipment needs to be handed over. We will keep it temporarily."

Lan An's face changed slightly, she was stunned for a moment and said, "Their parents don't know yet..."

"We will notify you one by one later." Lu Junchi said seriously, "We suspect that some people in this sand painting workshop have something to do with the recent car bombing. Please cooperate with the investigation."

The criminal police interrupted the work of the children in the studio and led them one by one to the outside hall for searching. They first had to make sure that there were no bombs or explosives here.

Lu Junchi called Qiao Ze: "No. 198 Yunan Road, we need police support here."

Su Hui stood aside and looked at the teenagers who moved out. They seemed to not know what happened, and their expressions were a little dazed.

He frowned. Could it be that the fine sand that has plagued Huadu for several years has been hidden in this small and crude sand studio?

This place has been open for more than a year, so who was Xisha before that?Where will he be?
