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

"The second point is that in the surveillance video, we can see the most realistic physical performance and behavior of the bank robber, rather than the secondary account of the witnesses at the scene.

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

Of course, we're just putting all our energy into the surveillance video for the time being, and see if we can find clues that Investigation Team 14 has overlooked.

We will not give up the other evidence, and we will look at it one by one in the future, but it is a matter of the order of viewing. ”

“OK。”

After listening to Luo An's words, everyone nodded in understanding, and Augustus didn't talk nonsense, and directly waved his hand, asking everyone to return to their workstations and start to check 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 hall, and then one of them took out black paint to smear the surveillance video, the whole process took less than ten seconds, and even the fastest one, 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 Luo An.

Everyone's eyes did not let Luo An be affected in any way, he carefully reviewed the surveillance video of the robbers entering the bank in six cases, 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?"

"Yes, you can, but if you do that, you won't be able to see the video at all."

Mona shook her head, it was 2005, the computer screen was so big, six videos were put together, and the portraits on the screen were very congested.

Not only that, but the quality of the surveillance video of these banks is also very average, far less clear than that of later generations, and if you zoom in a little, the characters in the video will be blurry.

"Okay."

Luo An nodded, didn't continue to dwell on the problem, and then began to slow down the video on the computer little by little.

At the same time, Luo An also took out a notebook in his hand, and wrote and drew while playing videos.

Seeing that Roan was obsessed with surveillance footage, Augustus patted his big belly and picked up a folder casually.

"Lacey."

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

"In addition to the hostages taken by the robbers, the bank clerks who were frightened by the information in the transparent folder also had close contact with the robbers, did they mention the robbers' faces, or the color of their pupils?"

Hearing August's words, Lacey pulled out the folder of her confession and flipped through it, looked at it carefully, and then shook her head and said:

"It is true that several bank clerks mentioned the color of the robbers' pupils, but they all mentioned everything, brown, black, dark brown.

As for the faces, several bank clerks said that they could see that each other's skin was white through the two holes in the eyes of the black hood. ”

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

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

Those bank clerks were ordinary people, with no professional training, and it was normal for them to have confused memories after being frightened.

In particular, the robbers also threatened their families.

"Huh?"

Thinking that the robber's transparent document bag contained information about the bank clerk's family, Augustus suddenly thought of something, tilted his head and asked:

"Have you investigated the robbers, how do you know the identity information of the bank clerks' families?"

"Investigation Team 14 has already checked it."

Hearing August's words, William next to him pulled out a folder and spread his hands:

"When the robbers threatened the bank staff, they provided the bank clerk's family information with simple names, contact information, and home addresses.

If we want to find out this information, we can get it from many sources, such as hospitals, post offices, schools, restaurants, etc., and the scope is too wide for us to know where the robbers got this information. ”

The United States has always boasted of valuing the privacy of its citizens and protecting their private information.

But in reality, the United States is one of the countries in the world with the worst leakage of personal information.

“OK。”

After listening to William's words, Augustus frowned, patted his stomach, and found the direction he could think of, the fourteenth investigation team seemed to have thought of it all, and they all conducted investigations, but in the end they didn't find any results.

In the final analysis, there is too little surveillance video in the outer area of the bank, and as soon as the robbers leave the bank, the figure disappears completely.

"I don't know if that's a clue."

After a long time, Mona suddenly spoke up, attracting the attention of the three:

"I found six robberies in which the bank robbers pushed open the bank doors in a way that pushed them inward and some pulled them outward."

Hearing Mona's words, Augustus and William glanced 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 one or two or four cases, the robbers all pushed the bank door inward, and in three or five or six cases, the robbers all opened the bank door outward, right?"

"That's right."

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

"Luo An had previously speculated that these six bank robberies were not committed by the same gang of robbers."

Seeing the confusion in Augustus and Lacey's eyes, Mona briefly told them about the previous trip they had gone to investigate the owner of the laundry.

"This ......"

After listening to Mona's introduction, William was very shocked by Elken's courage, and Augustus was thoughtful, tilted his head and said:

"If these six cases were not done by the same gang, it can explain why Brosson did not succeed in solving the case."

If the direction is deviated, no matter how hard you try, you won't get the answer you want.

Augustus's words came into Lacey's ears, she raised her eyebrows, called up the surveillance video on the computer, and her expression was solemn:

"In each of the six cases, the robbers opened the bank door in a different way, some pulling backwards and some pushing forward. Judging from this situation alone, 124 cases were a gang of robbers, and 356 cases were a gang of robbers.

But if you look at the robbers' actions of spray-painting the cameras, 146 cases are left and then right, and 235 cases are left and then left......"

Ignoring the dress and other aspects, from the perspective of the robbers' actions alone, although the robbers generally committed the same crime, although the robbers generally committed the same crime, there were many differences in the details of the actions, and each time a new permutation and combination appeared.

There are so many permutations and combinations that it is impossible to deduce which case was done by which group.

"This ......"

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

On the side of several people, Luo An didn't say a word, but the notebook in his hand was already full of several pages of text.

The video screen in the computer was still playing slowly, and 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:

"Roan, did you find anything?"

"I found a couple of small details."

Seeing that several people were looking at him, Luo An didn't hide anything, and said while adjusting the video in the computer to the corresponding position:

"Watch out"
