Wang Song's workload here is still relatively large, and he has already asked all the online stores.
But so far no substantial clues have emerged.
According to Wang Song's analysis, the robbers should have already considered this when purchasing explosion-proof clothing. The police will inquire about the source of the explosion-proof clothing through online channels.
So even if they bought it online, they might have mailed it to other places and then transferred it to BZ City in some way.
If there is only this one clue, then Wang Song will investigate from all over the country to look for clues.
Then there is offline purchasing.
There are currently no clues in this regard.
There are some security companies here in BZ City.
But these security companies will not equip their employees with such 100% protective explosion-proof clothing.
But they should have offline channels to purchase explosion-proof clothing. Mr. Wang has sent people to investigate, but time is too tight, and no particularly many clues have been reported back yet.
Next is Song Mingguang.
The investigation into the internal situation of the bank is all on Song Mingguang's side.
“We have made two main assumptions here. The first assumption is that the robbers’ actions were a predetermined plan, and we did not know that the bank had a large amount of additional cash deposited.”
“ If there is an insider in the bank in this case, the other party should notify the robbers at an earlier time by phone or text message when the robbery will take place. "
"Another assumption is that the other party is in the bank. After discovering that a coal mining company deposited a large amount of cash, he sent a message to the robbers, who then took action.”
"According to the clues obtained from the investigation, in both banks, coal mining companies deposit money in the afternoon."
"We focus on the time period when the other party deposits money, and investigate the situation when someone calls a mobile phone or sends a text message, etc. An investigation was conducted."
"Especially the bank was robbed."
Song Mingguang turned on the projection, and there was an analysis table on it.
“Theoretically speaking, the insider is most likely to be robbed of a bank, because this way the robbers can get the most accurate information about the payment vehicle.”
"The time for depositing money in the coal mine is 5 p.m., and the time for robbery is 6 p.m."
"During this period, 39 mobile phone calls were made from the bank."
"We have The call recipients were tracked. "
" As a result, there are some findings. "
"The teller at the counter who handled the coal deposit business was named Zhang Xiaoyu. She called after finishing the business. Make a phone call.”
"The time is 8 seconds, and the person on the call is her boyfriend."
"According to bank regulations, members are not allowed to make calls during work hours. It is actually a violation for the other party to call at this time."
“And she only lasted 8 seconds on the phone with her boyfriend. What could she have done in such a short period of time?”
“There was also a cleaner who made a deposit in the coal mine. Made a short phone call.”
“The call was made to his nephew, and the call lasted only 4 seconds.”
"We think this person can also be included in the key observation targets."
"The other calls lasted more than one minute, and the longest one was 23 minutes."
"Logically speaking To put it bluntly, if the other party is tipping off the information, the time must be very short, so I think the person who made the call for too long is unlikely to be a robber."
"There are similar situations at the other two banks. We are now. They are being analyzed one by one, and two groups of people have been sent to the scene to investigate the suspected persons. "But so far, there has been no breakthrough."
Everyone was listening carefully to Song Mingguang's report.
The investigation here has actually made some progress and results, but there has been no decisive breakthrough yet.
Based on the information currently provided by Song Mingguang or investigated, the possibility of an insider seems to be high.
But this is just a guess, because the time for the car to arrive at the bank is basically fixed.
As long as the robbers observe more, visit more places, or have relevant work experience, they can easily grasp the deposit rules of the unpaid vehicles.
"Lao Luo, how is the situation here?"
Luo Qiang is responsible for investigating the situation of the staff of the escort company.
"The first is the three loan officers."
The first thing Luo Qiang investigated was the background of the three escort officers.
According to the situation shown in the surveillance, it can be seen that the three escorts basically did not resist after being pointed at a gun.
Although what the robbers said gave everyone a psychological boost, in fact the escorts were more formal than substantive in the escort process.
So the first thing Luo Qiang needs to rule out is whether the three escorts were involved in this case.
From the perspective of criminal investigation, this is very possible.
The escort funds were stolen and several escort personnel were fired at most and would not bear any legal responsibility.
Because as the robbers said at the time, they were standing very close to each other at the time, and the other party was using a shotgun. If an accident really happened, then it is very likely that an accidental injury would occur, or in other words, an accidental injury would definitely occur. .
Everyone made very accurate choices in terms of protecting money and protecting life.
So, since there is no responsibility and there are high-sounding reasons not to resist, why can't the three escorts participate?
“Currently, people like me are conducting detailed investigations into the family backgrounds, financial status, interpersonal relationships, etc. of the three escorts.”
“There are no clues yet about how the other party is holding on. ."
"In addition, there is the situation of the personnel who left the escort company."
"The situation of this survey... is not optimistic, because the resignation rate of their company is relatively high."
"In just the past six months, twelve people have resigned or been fired."
"In the escort company, I checked their personnel file information. This company has relatively frequent personnel turnover."
"Generally speaking, more than 20 people come in and out a year."
" Therefore, the workload is quite heavy when investigating from this aspect, and it is not particularly easy to find outstanding clues.”
"More people have resigned?"
Li Donglin didn't say resignation, but specifically asked about resignation.
Luo Qiang naturally knows what he means: "The management of this company is relatively strict. When working, the escorts are strictly prohibited from smoking, making phone calls, and chatting."
"As long as you violate these regulations , which ranges from deducting a month’s salary and bonus to directly dismissing them.”
“So the staff they fired accounted for about 50% of all the employees who resigned.”
"Judging from the results of today's daytime visit and investigation, it is quite obvious that some employees who have resigned are dissatisfied with this company."
"So, there is collusion between the inside and outside, and the resignation and the current employees act together to commit a robbery. It’s not impossible.”(End of Chapter)
