"Crack!"

As soon as Brown entered the office of the Robbery and Murder Division, he was slapped hard in the face.

Li Mei pointed at his nose and said angrily, "You self-righteous bastard, you almost killed my daughter."

"What about you, what are you doing? Have you ever cared about your daughter?

I only care about my career all day long and want to become the leader and mayor of Los Angeles!"

"I don't want to quarrel with you, but you did something wrong in this matter. Not only did you miss the best opportunity to rescue your daughter, you may even kill your daughter."

"I just tried my best to rescue my daughter and let her return to me safely."

"I know you don't like government departments, but you shouldn't play with your daughter's life. Professional matters should be left to professionals.

You have to learn to trust."

Susan interrupted the two people, "Boy, this is not the place to quarrel. The most important thing right now is to rescue Betty. There is no point in blaming the other party now.

Also, Mr. Kenneth, I want to ask you something.

If Deputy Luke hadn't discovered you in time.

What would you do now?

Prepare for ransom again? Or call the police?”

Apparently Susan was also a little dissatisfied with Kenneth's behavior.

Brown Kenneth waved his hand, "I don't know, and I didn't expect things to turn out like this. Those damn bastards actually don't keep their words."

Brown seemed to remember something, "Have you traced the kidnapper's cell phone?"

"The kidnapper temporarily changed his mobile phone number. We also tried to track the new mobile phone number, but the call time was too short and it was difficult to determine the specific location of the mobile phone." Susan only said half of what she said. Although the specific location of the suspect could not be determined, it was still possible.

The general area determined by the mobile phone signal tower is just large, making it very difficult to investigate, and it may not be possible to trace the traces of suspicious persons.

Li Mei asked, "Captain Susan, what are you going to do now?"

Susan said, "Mayor Li, Mr. Kenneth, you can go to the lounge and wait. We will notify you after we have a meeting to discuss the next step of the investigation plan."

Brown asked, "My daughter is in danger right now, and you don't do something and you continue to have meetings?"

The deputy pointed at Brown and shouted, "Shut up!"

Who gave you the courage to accuse the police like this? The reason why things have reached this stage is because you concealed the fact that the kidnappers were extorting money.

It's best to keep your mouth shut until the police make a record of it for you."

The deputy team leader was an old man with a fierce face, and he was even more frightening when he lost his temper, which really shocked Brown.

Rhett stood up to smooth things over, "Hey, everyone's purpose is to rescue Betty, so please calm down. Only if we trust each other and cooperate with each other can we handle this matter well.

Mr. Kenneth, our meeting is not to be lazy, nor to respond passively, but to brainstorm, compile clues, and analyze the kidnapper's next move.

Only by considering everything comprehensively can we ensure Betty's safety as much as possible.

Marcus, take Mr. Kenneth to the lounge."

After Li Mei and Brown left, Susan called everyone to the conference room for a meeting.

"Everyone, the situation of the case has changed. Please share your views."

The deputy team said, "Immediately check for suspicious persons within the scope of the signal tower, notify the local patrol department to cooperate, and also call out surveillance to see if there are any suspicious persons around during the time of the call."

Matthew said, "There is not just one signal tower that receives mobile phone signals, but four signal towers. The area is not small, so it is difficult to investigate."

Susan said, "Then draw a circle with the four signal towers as the center. Is it possible that their intersection is where the suspect was when he made the call?"

Matthew shook his head, "This is not a math problem. You can still receive the signal even if it is not the intersection. As I said, it is difficult to judge accurately. I can only draw a rough range."

"OK, then do it. Even if the possibility is small, it is better than not doing it." Susan responded, "What other ideas do others have?"

Luke replied, "I think we should go to the ransom delivery location to check. Although it is unlikely that the suspect will leave any clues, what if?

And you can call the surrounding surveillance and the surveillance within the cell phone tower for comparison. If the person who made the extortion call and the person who took the ransom are the same person, you can determine the identity of the other party through surveillance comparison."

Susan nodded, "It is true that we have to go to the ransom delivery location, but considering that the kidnappers may still pay attention to the situation there, it is best not to conduct a high-profile investigation."

…

Half an hour later.

The back alley of Wheaton Steakhouse.

A slovenly black homeless man walked into the alley. As he walked, he complained, "You said you don't want a high-profile investigation, do you have to dress like this?"

Xiao Hei reluctantly walked to the trash can, lowered his head to check the garbage in the trash can, and then rummaged around in the trash can, his black face was distorted by the smoke,

"How do I look like a tramp?

Why am I left to dig through the trash can alone?

What a bunch of nasty guys.”

Although he complained, the work had to continue. Xiao Hei rummaged for a while and found nothing suspicious. He took out his mobile phone and took a few photos, which was enough to hand in the work.

Xiao Hei left the back alley, observed the surrounding situation, and saw that no one was following him. Then he took off his worn coat and ran back to the Ford.

Luke asked, "Did you find anything?"

Xiao Hei curled his lips, "Yeah, a lot of stinking kitchen waste."

"No backpack containing cash?" According to Brown's description, he packed the money in a black backpack.

"No, maybe the kidnapper took the schoolbag away with him. This is normal. After all, there is two hundred thousand dollars in it. Putting it from one backpack to another might be discovered by passers-by."

"Well done, thank you for your hard work." Luke encouraged.

Xiao Hei stretched out his right hand, preparing to open the door and get in the car.

Luke yelled, "Hey, are you sure you want to come up here?

"What do you mean?" Xiao Hei looked confused.

"You just dug through the trash can and now you're sitting in the car and you're going to make the car dirty, which will affect both of us physically and mentally for at least a few days.

You'd better take a taxi back.

I'll reimburse the fare for you, you're welcome." After Luke finished speaking, he stepped on the accelerator and left.

Xiaohei "..."

…

The next morning.

Robbery and Murder Division, 1st Squadron.

In the office.

Susan, Jenny, Raymond, and Matthew all have panda eyes.

Considering that the kidnappers might call at any time, the four of them stayed in the office on duty.

Luke, Xiaohei, and the deputy team went home to sleep.

In the morning, Luke walked into the office carrying two bags of breakfast, "Guys, it's time for breakfast."

The deputy team leader asked, "Do you have food if you don't work overtime?"

"Of course, burgers, burritos, donuts, milk tea, coffee, French fries, you can take whatever you want." Luke waved his hand.

"Thank you." Susan took a cup of milk tea.

Luke had donuts in his left hand and sugar-free coffee in his right hand, "Captain, what happened last night?"

Susan took a sip of milk tea and said, "We checked the surveillance all night and found no suspicious persons. But Matthew found a new clue."

Matthew just picked up the burger and took a bite. He said with a vague expression, "Let me fill my stomach first. I'm almost hungry."

After finishing a burger, Matthew drank another cup of coffee and then showed a satisfied look, "Deputy Luke, thank you for the breakfast. I feel like I'm alive."

Luke raised his coffee cup to signal.

Matthew took out a document from the table, "The captain asked me to investigate Amy Ma's communications. I found that Amy Ma rarely contacted the outside world. Her mobile phone number was very clean and she had never registered any other software.

I feel like this is a bit unusual and I suspect she may have another mobile phone number.

Sure enough, I investigated Mr. Kenneth’s home network IP and found that there was a chat software that frequently logged in and used Mr. Kenneth’s home WiFi.

For this reason, I specifically asked Mr. Kenneth. According to him, no outsiders use the WiFi at their home. Only he, Betty, and nanny Amy Ma know about it.

And he has never used that chat software, so I suspect that the chat software is probably used by Amy Ma."

Matthew said, putting a piece of information on the projector, "This is a screenshot of a chat software. This chat software has a special name called 'WeChat'.

Maybe everyone has never heard of this chat software, but it is one of the top three chat software in the world in terms of users.

The main user group is Chinese. I used it yesterday. This chat software is very interesting.

In addition to chatting, this software can also publish a circle of friends, where you can post some life videos and pictures.

Amy Ma is very active on this software and uses it almost every day.
