Sand does not appear out of thin air, every grain of sand is processed, and then placed in the hands of bombers, and then placed in those bombs.
The police contacted the sand factory that produced the sand, and the factory also cooperated very well, taking out all the production and sales data for them to check. A salesperson who lives in Huadu was specially dispatched to the General Administration for inspection.
After testing, these sands are indeed produced by the sand factory in Xinxian County, and peacock blue is the latest color released this year.
And the wholesalers who bought these sands were narrowed down to just a few.
In addition, cross-comparison 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 marker, and he probably did not expect that it was these very common colored sands that finally revealed his whereabouts.
Lu Junchi divided the serious crime team and the previous task force 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 100 people were screened.
Su Hui looked at the list, and one of the names, Lan An, caught his attention. This is a 27-year-old young lady who runs a special sand bottle painting workshop.
It is said to be special, because the workers of this sand bottle painting workshop are all special people, that is, some disabled people with mild autism or disabilities.
Their job is to fill in 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 Jun late, "I want to go here and check it out."
Lu Jun nodded slowly: "Okay, I'll prepare right here, bring a few detectives, and accompany you."
This sand painting workshop is located in an alleyway on the outskirts of Huadu City. It is not easy to find. Lu Junchi parked his car outside and entered with Su Hui.
The sand bottle painting workshop is not big, with a total of more than 100 square meters. The left side is the place for painting, the right side has a partition, behind the partition are piled various raw materials, and there are several shelves at the back of the room, on which are placed Finished sand bottle.
On the front side of the house, facing the street, is a floor-to-ceiling window with some of the finest sand bottles.
The female boss Lan An looks very young and beautiful, and she speaks very gently: "This place has been in business for more than a year, and the purpose is to provide a place for these children to work..."
Lu Junchi checked over there, Su Hui leaned on a cane and observed the small and simple sand bottle studio in front of him.
There are several tables in the studio. There are various sand bottles and colored sand on the tables. Several young people are painting sand bottle paintings at their desks. They were silent and focused, paying no attention to the visitors.
Inevitably, a lot of fine sand fell on the floor of the room.
"I think there are already eight people here, why aren't their names on the register?" Lu Junchi asked.
"Some of them are disabled and some are still young, so there are some omissions in the previous registration list..." Lan An's face showed a trace of embarrassment, "Well, Mr. Police, you don't think these children will be criminals Well... many of them can't take care of themselves at all, let alone go out for a walk. Coming here every day from home is considered a long trip for them. Moreover, they are all good children with simple minds... "
Some of those children are unable to go to school, and they may be underage when calculated, and 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 in will affect the police's judgment, so I hope Miss Lan can register it truthfully."
"Okay..." Lan An brushed her hair and took the registration form, "I'll write each of them on the form."
"Including their home addresses, mobile phone information, etc." Lu Junchi warned.
Lan An hummed, took out the pen, and began to fill in the information booklet left in the past.
"Are you married?" Lu Junchi looked at the woman and asked her suddenly.
In her form, her relatives were not listed. If she runs this sand painting workshop here, then her family will also have the opportunity to come into contact with the sand.
Lan An paused, raised his head and said, "My parents have passed away, 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 with disabilities?"
"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. Both this disease and autism belong to ASD in diagnosis..." Lan An lowered his head and continued to fill in, "The child with the disease has poor language ability, and the older The movements are uncoordinated, and some words can be repeated, but it does not affect life too much. It is generally difficult to integrate into the society with autism, but Asperger's is different. With long-term training, children can easily communicate with people. Do the work and be self-reliant.”
Lan An simply finished writing the information of those people, and Lu Junchi held the papers one by one.
He wants to make sure that the person's name and person can be numbered one by one.
"Are there many children in this situation in the studio?"
"This is the case with the boy named Dong Anchen and the girl named Xu Sha."
"Who is Dong Anchen?"
Lan An pointed.
Lu Junchi followed her hand, it was a very clean looking boy, he lowered his head and focused on the sand bottle in his hand. The boy was between a teenager and a young man. He looked like he was about twenty years old. If Lan An had not told him about his situation, Lu Junchi would hardly have seen that the young man in front of him was a patient.
"Where's Xu Sha?"
Lan An pointed to him again.
Lu Jun said lately, "I want to ask them some questions."
Lan An clapped his hands and said to them as if he was coaxing children: "Today, uncles from the police came to see you painting. They may ask you some questions later. Don't be nervous, just answer whatever you know."
Lu Junchi started to ask those workers questions, but Lan An was empty, and she walked to Su Hui's side.
Su Hui stared at the window, which contained many completed sand bottle works.
Many sand bottle paintings are very simple, just overlapping layers of colored sand, 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 took a sand bottle and handed it to him.
"Who doesn't like beautiful artwork?" Su Hui looked down at the sand bottle in his hand, and then pointed to a few sand bottles inside and asked, "Whose works are these?"
Even if he has poor eyesight, he can still see that the paintings in those sand bottles are very complicated and the color matching is very beautiful.
Lan An arranged the sand bottles with her slender fingers and replied, "Those are painted by Yu Keke. She has a high artistic talent. Many customers will buy the sand bottles she painted."
"Is she here now?" Su Hui asked.
Lan An shook his head, showing a somewhat regretful expression: "She hasn't come to work here recently."
"Why didn't you come?"
"Probably because it's inconvenient to come here. We are a bit biased here. She told me that she wanted to paint it at home and send it over."
"When did she not come here?"
"About a month ago." Lan An replied casually, "I also registered her name on the record sheet."
Lu Junchi asked the young people a few questions and heard about Yu Keke. He pointed to a group photo of young people on the wall of the painting workshop: "Is Yu Keke this girl?"
Lan An nodded: "Yes, her feet are congenitally deformed, and it is inconvenient to go out. After doing it here for a while, I will not 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 by bus every day..." A girl on the side raised her head and suddenly interrupted.
Lu Junchi remembered that she was the girl named Xu Sha.
The whole studio fell silent, and the air froze for a while.
Lan An was a little embarrassed: "That might be because I didn't pay attention sometimes..."
"Does any of you know which bus she is on?" Lu Junchi asked again.
Some of these children are mentally underdeveloped, and some are physically disabled. They all raised their heads and looked at Lu Junchi, hesitating whether to speak.
"Bus 78," a boy finally said.
Lu Junchi and Su Hui glanced at each other. Bus No. 78 was within Duan Siyuan's range of activities. Nothing can arouse the desire of a beast more than a handsome, shy, and immobile prey that cannot be resisted.
Lu Junchi squatted down and asked the girl, "Has Yu Keke mentioned to you that something strange happened on the bus..."
Xu Sha, who had spoken to before, was suddenly a little afraid to speak. She turned her head subconsciously, wanting to find Lan An.
Lan An was about to walk over, when Su Hui reached out and held her.
Lu Junchi squatted down in front of the girl: "it's okay, you tell the police brother, we will help her."
Only then did 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 boys also began to speak.
"Well, because there are bad people, Yu Keke doesn't come to work here."
"If the bad guy is gone, she'll be back..."
"The bad guy deserves to die."
In the sand painting workshop, there was a sudden sound, someone accidentally knocked over a sand bottle, and some colored sand fell on the ground.
Everything is finally connected, the colored fine sand, the molesters on the bus.
Lu Junchi looked at the young people in front of him, most of them were in their twenties, some of them were not mentally intelligent, and their expressions didn't change much when discussing issues.
This sand painting workshop was really related to the Xisha case. Lu Junchi got up and walked over to the policemen who were 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 painting workshop is temporarily closed, everyone here needs to be further interrogated, and the painting workshop also needs to be searched. All of you need to hand over the communication equipment, Let us keep it for the time being."
Lan An's face changed slightly, she froze for a moment and said, "Their parents don't know yet..."
"We will inform you one by one later." Lu Junchi said solemnly, "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 detectives interrupted the work of the children in the studio and led them to the outside hall one by one to conduct a search. First of all, they had to make sure that there were no bombs and explosives here.
Lu Junchi called Qiao Ze: "No. 198 Yunan Road, police support is needed here."
Su Hui stood aside and looked at the teenagers who moved out. They didn't seem to know what was going on, 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 rudimentary sand studio
It has been in business for more than a year, so who was Xisha before that? Where will he be
