Hearing Lacey and Mona's questions, Luo An coughed lightly and continued to explain:
“Second point, in the surveillance video, we can see the most realistic physical expressions and actions of the bank robbers, rather than the secondary narration of witnesses at the scene.
This is the most relevant and authentic information we can truly rely on when looking for a robber.
Of course, we are only temporarily focusing all our energy on the surveillance video to see if we can find any clues that the No. 14 Investigation Team has ignored.
We will not give up on other evidence and will review them one by one in the future. It is just a matter of the order in which they are viewed. "
"OK."
After listening to Luo An's words, everyone nodded in understanding. Augustus didn't waste any time. He waved his hand and asked everyone to return to their workstations and start checking the surveillance video.
There were a total of 6 bank robberies. Two robbers dressed in black, from opening the bank door to entering the bank lobby to one of them taking out black paint and smearing the surveillance video, the whole process took less than ten seconds, even the fastest one , only seven seconds.
Seeing this scene, Mona's eyelids trembled, and the others also had complicated expressions, and they all turned their attention to Luo An.
The crowd's gaze did not affect Luo An in any way. After he carefully checked the surveillance videos of the six robbers entering the bank, he remained silent for a while and tilted his head to look at Mona:
"Mona, can you put these six videos on the same screen and let them play together?"
"You can, but if you do that, the video will be completely unclear."
Mona shook her head. The time was 2005, and the computer screen was only that big. With six videos put together, the portraits on the screen were very crowded.
Not only that, the quality of the surveillance videos of these banks is also very average, far from the clarity of later generations. If you zoom in a little, the characters in the videos will be blurry.
"All right."
Luo An nodded, did not continue to dwell on this issue, and then started to slow down the video on the computer bit by bit.
At the same time, Luo An also took out a notebook and wrote and drew while playing the video.
Seeing that Luo An was addicted to the surveillance video, Augustus patted his big belly and picked up a folder.
"Lacie."
Augustus briefly browsed for a moment, turned to look at Lacey, and asked:
"In addition to the hostages held by the robbers, the bank employees who were frightened by the information in the transparent folders also had close contact with the robbers. Did they mention the robber's face or the color of his eyes?"
After hearing Augustus' words, Lacey took out the confession folder and flipped through it. After examining it carefully, she shook her head and said:
“A few bank employees did mention the color of the robber’s eyes, but they were all different colors, brown, black, dark brown, they all mentioned it.
As for the face, several bank employees said that through the two holes at the eyes of the black hood, they could see that the other person's skin was white. "
"It seems that the threat of Mr. White Robber frightened these ladies."
When Augustus heard what Lacey said, he shook his head and said nothing more.
Those bank employees are ordinary people without professional training. It is normal for their memory to be confused after being frightened.
Especially when the robbers threatened their families.
"Um?"
Thinking that the robber's transparent document bag contained information about the bank employee's family, Augustus suddenly thought of something, tilted his head and asked:
"Have you ever investigated how the robbers knew the identity information of the family members of the bank employees?"
"Investigation Team No. 14 has already investigated."
After hearing Augustus' words, William next to him pulled out a folder and spread his hands:
“When the robbers threatened bank employees, they provided only simple names, contact information, and home addresses of the bank employees’ family members.
If you want to investigate this information, you can get it from many channels, such as hospitals, post offices, schools, restaurants, etc. The scope is too wide, and we have no way of knowing where the robbers obtained this information. "
The United States has always boasted that it values citizens' privacy and protects their private information.
But in fact, the United States is one of the countries in the world that leaks most serious personal information.
"OK."
After listening to William's words, Augustus frowned, patted his belly, and found that the No. 14 Investigation Team seemed to have thought of all the directions he could think of and conducted investigations, but in the end they found no results.
In the final analysis, there are too few surveillance videos in the peripheral areas of the bank. As long as the robbers leave the bank, they will completely disappear.
"I don't know if this is a clue."
After a long time, Mona suddenly spoke, attracting the attention of the three people:
"I found six robberies where the bank robbers pushed open the bank door in a way that either pushed it inward or pulled it outward."
After hearing Mona's words, Augustus and William looked at each other, and both saw the confusion in each other's eyes, but Lacey on the side nodded:
"You want to say that in cases one, two, and four, the robbers pushed the bank door inward, and in cases three, five, and six, the robbers opened the door outward, right?"
"That's right."
Mona nodded, then tilted her head and explained to August William and others:
"Luo An had previously speculated that these six bank robberies were not committed by the same group of robbers."
Seeing the doubts in August and Lacey's eyes, Mona briefly introduced to them the previous incident where they went to investigate the laundry owner.
"this……"
After listening to Mona's introduction, William was very shocked by Elken's courage, while Augustus tilted his head thoughtfully and said:
"If these six cases were not carried out by the same group of people, it would explain why Blossom failed to successfully solve the case."
If there is a deviation in the direction, no matter how hard you try, you will not get the answer you want.
August's words reached Lacey's ears. She raised her eyebrows and called up the surveillance video on her computer with a solemn expression:
"In the six cases, the robbers opened the bank door in a different way each time. Some pulled it back and some pushed it forward. Judging from this situation alone, cases 1, 2 and 4 were a group of robbers, and cases 3, 5, and 6 were The case involved a group of robbers.
But if you focus on the actions of the robbers who paint the camera with spray paint, in cases 146, they start from left and then right, and in cases 235, they start with right and then left..."
Ignoring the clothing and other aspects, just looking at the robbers' movements, in the six cases, although the overall committing methods of the robbers were the same, there were many differences in the details of the movements, and a new permutation and combination appeared every time.
A lot of actions lead to a lot of permutations and combinations, and it's impossible to deduce which case was committed by which group of people.
"this……"
After hearing what Lacey said, Mona and August frowned.
Standing beside them, Luo An didn't say a word, but the notebook in his hand was already filled with several pages of text.
The video screen on the computer was still playing slowly. Suddenly, Luo An's pupils shrank, and he suddenly drew a circle on one of the lines of text on the notebook page.
Mona on the side saw Luo An's movements and hurriedly asked:
"Luo An, did you find anything?"
"I found a few little details."
Seeing that several people were looking at him, Luo An did not hide anything. He adjusted the video on the computer to the corresponding position and said:
"Watch carefully"
