Chapter 575 (1/2)

Ling Yan bit her teeth. Unexpectedly, they were so unscrupulous to investigate.

”Even the polygraph is here. You're closer than the police.”

With a lie detector, some changes in the body's data may become the focus of their suspicion.

”We all hope to find out the murderer earlier.” Watson said.

Is this Ling Yan really miss Wei's friend?

Why, he always felt that she didn't want them to investigate the murderer so much?

”Of course.” Ling Yan reluctantly smiles.

Watson's men came over and said, ”it's all over.”

”Mrs. Ling, Miss Ling, the machine has been debugged in a few days. We will invite you to come over.”

Watson finished, and left Ling's home with others.

Ji Fang saw them go, and Ling Yan helped them up the stairs.

As soon as I got into the bedroom and sat down, I couldn't help saying.

”They even sent the lie detector. They are...”

Before she finished speaking, Lingyan reached out to cover her mouth.

Then, I typed a line on my mobile phone.

[be careful they're bugging. ]Ji Fang thought of the possibility and stopped talking immediately.

The mother and daughter searched the room for a long time, and they found the extremely hidden eavesdropper.

She typed a line on her cell phone: [we have to think of a way to get past the lie detector. ]

if it's just a general cross examination, they can deny it.

But with a lie detector, even if they deny it, changes in their body data can make them suspicious.

Ling Yan also typed a line of words: ”we have to find a way to talk about it tomorrow. ]

they have installed a bug at home and certainly in the hospital office.

If they talk about Gu Weiwei, they will hear them.
