Legendary FBI Detective

Hearing Lacey and Mona's question, Roan coughed lightly and continued to explain:

"Second point, in the surveillance video, we can see the most authentic physical performance and behavior of the bank robbers, rather than the secondary narrative of the witnesses at the scene.

This is the most relevant and authentic information we can really rely on when looking for robbers.

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 overlooked.

We will not give up other evidence, and we will check them one by one later, it is just a matter of the order of checking. "

"OK."

After listening to Roan's words, everyone nodded in understanding, and Augustus didn't talk nonsense. He just waved his hand and told 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, and then one of them took out black paint and smeared the surveillance video. The whole process took less than ten seconds, even the fastest time. , only seven seconds.

Seeing this scene, Mona's eyelids trembled, and the rest of the people also had complicated expressions, and they all turned their eyes to Roan.

The eyes of everyone did not affect Roan in any way. After carefully checking the surveillance video of the robbers entering the bank in the six cases, he was 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?"

"It can be done, but if you do that, the video will be completely unreadable."

Mona shook her head. It was 2005 at this time, and the computer screen was only that big. Six videos were put together, and the portraits on the screen were very crowded.

Not only that, but the quality of the surveillance videos of these banks is also very average, far less clear than those of later generations. If you zoom in a bit, the characters in the videos will be blurred.

"All right."

Luo An nodded, did not continue to dwell on this problem, and then began to slow down the video on the computer.

At the same time, Luo An also took out a notebook in his hand, and played the video while writing and drawing.

Seeing that Roan was addicted to the surveillance video, Augustus patted his belly and picked up a file folder.

"Lacey."

Augustus briefly flipped through it for a while, then turned to look at Lacey, and asked:

"In addition to the hostages held by the robbers, the bank staff who were frightened by the information in the transparent folder also had close contact with the robbers. Did they mention the robber's face or pupil color?"

Hearing what Augustus said, Lacey took out the folder of the confession and flipped through it. After careful inspection, she shook her head and said:

"A few bank employees did mention the color of the robber's pupils, but they could be any color, brown, black, dark brown, they all mentioned it.

As for the face, several bank employees said that through the two holes in the eyes of the black hood, they saw that the other person's skin was white. "

"It seems that the threat of Mr. White Robber frightened these ladies."

Augustus shook his head when he heard Lacey's words, but didn't say much.

Those bank staff are ordinary people, without professional training, and it is normal for them to have memory confusion after being frightened.

In particular, the robbers threatened their families.

"Um?"

Thinking of the robber's transparent file bag containing information about the family members of the bank staff, Augustus suddenly thought of something, tilted his head and asked:

"Have you investigated the robbers, how did you know the identity information of the family members of the bank staff?"

"The investigation team on the 14th has already checked."

Hearing what Augustus said, William next to him pulled out a folder and spread his hands:

"When the robbers threatened the bank staff, the bank staff's family information was only a simple name, contact information, and home address.

If you want to check this information, you can get it from many sources, such as hospitals, post offices, schools, restaurants, etc. The scope is too wide, and we have no way of knowing where the robbers got this information. "

The United States has always boasted that it values ​​citizens' privacy and protects citizens' private information.

But in fact, the United States is one of the countries that leak personal information most seriously in the world.

"OK."

After listening to William's words, Augustus frowned, patted his stomach, and found that the investigation team on the 14th seemed to have thought of all the directions he could think of, and conducted investigations, but in the end they found nothing.

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 disappear completely.

"I don't know if this counts as a clue."

After a long time, Mona suddenly made a sound, which attracted the attention of the three of them:

"I found six robberies where the bank robbers pushed the door open, some by pushing it in, some by pulling it out."

Hearing what Mona said, Augustus and William looked at each other, and both saw the doubt in each other's eyes, but Lacey nodded:

"You want to say that in one, two or four cases, the robbers pushed the door of the bank inward, and in three or five or six cases, the robber opened the door of the bank outward, right?"

"That's right."

Mona nodded, then tilted her head and explained to August William and others:

"Roan had previously speculated that these six bank robberies were not committed by the same group of robbers."

Seeing the doubts in the eyes of Augustus and Lacey, Mona briefly introduced to them what they had done to investigate the owner of the laundry shop.

"this……"

After listening to Mona's introduction, William was shocked by Erken's courage, while Augustus tilted his head thoughtfully and said:

"If these six cases were really not committed by the same gang, it would explain why Brosen failed to 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.

Augustus' words reached Lacey's ears, she frowned, and called up the surveillance video in the computer with a solemn expression:

"In the six cases, the way the robbers opened the door of the bank was different each time. Some pulled back and some pushed forward. Judging from this situation alone, one, two, four cases were a group of robbers, three, five, six The case was a group of robbers.

But if you focus on the movements of the robbers using spray paint to smear the camera, 146 cases are left first and then right, and 235 cases are right first and then left..."

Ignoring the attire and other things, just looking at the robbers' actions, in the six cases, although the robbers' overall crime methods are the same, there are many differences in the details of the actions, and each time there will be a new permutation and combination.

With a lot of actions and a lot of permutations and combinations, it is impossible to deduce which group is responsible for which case.

"this……"

After listening to Lacey's words, Mona and Augustus frowned.

Beside the few people, Roan didn't say a word, but the notebook in his hand had already written several pages full of text.

The video screen on the computer was still playing slowly. Suddenly, Luo An's pupils shrank, and suddenly he forcefully drew a circle on one of the lines of text on the page of the notebook.

Mona on the side saw Roan's movements, and hurriedly asked:

"Roan, did you find anything?"

"I found a few small details."

Seeing that several people were looking at him, Roan did not hide anything, and while adjusting the video on the computer to the corresponding position, he said:

"Watch carefully"
