At 9:30 pm, Xu Yao finally returned to the hotel. As soon as he saw Mo Xiaoqing, he asked how the situation was going.

"I went to the police station under the jurisdiction of this place and checked out the previous case involving Li Tieer. At that time, Li Tieer was abused by his adoptive father and even went to the police station.

There are records in the police station that Li Tieer's adoptive father had been reported to the police by neighbors because of three abuses and violent disorder.

And the degree of domestic violence was very serious. I couldn't bear it when I saw those photos.

Li Tieer's whole body was covered with marks of burns from cigarette butts, and there were more..."

Xu Yao glanced at Mo Xiaoqing, coughed a few times, and then stopped talking.

Mo Xiaoqing urged, "Xu Yao, what methods did he use to abuse him?"

Xu Yao coughed twice and then spoke: "Li Tie'er's adoptive father in the United States has a habit of abusing children, involving child sexual abuse.

So, you can imagine what kind of life Li Tie'er lived in the United States? How much trauma would he suffer in his heart?"

Mo Xiaoqing was also shocked when she heard it. Xu Yao opened his mobile phone and handed it to Mo Xiaoqing to look at the photos inside. Every photo was shocking. There were photos of Li Tie'er being locked around his neck with an iron ring and made to kneel on the ground.

There were also photos of him being tied up with belts in a shameful way, with blood all over his body.

Mo Xiaoqing couldn't bear it any longer and couldn't help but shouting loudly: "Why didn't the police stop such a big thing and deprive Johnson of his custody rights?"

Xu Yao murmured: "The police also intervened, but Li Tieer was able to stay with his adoptive father, and it was all his own will."

When Mo Xiaoqing heard this, she was so shocked that she forgot to restore her jaw. Could it be that Li Tieer has become so perverted that he likes to endure this kind of abuse?!

In fact, this is not impossible. They have encountered many cases in which some people acted as perpetrators, while others were willing to commit this kind of twisted violence.

"So, Captain Xu, have the police found out that Li Tieer was responsible for Johnson's death?"

"We need to continue investigating this, but we don't know yet." Xu Yao turned around, sat down on the bed, rubbed his temples, and said,

"Our priority now is not to confirm this murder, but to confirm Li Tieer's whereabouts.

Where is Li Tieer now? We have traced his past life trajectory, which will help us to try to psychologically hinder him during the arrest process."

So far, Mo Xiaoqing has begun to understand why Li Tieer wants to retaliate against the staff of the welfare home.

His life is full of ups and downs, which may also be related to the discrimination he suffered in the welfare home during his childhood.

If he could meet a healthy family after he was released, and embrace him with love, perhaps he would not have ended up like this today, and there would not be such a devilish murderer.

But if it is an if, Li Tieer's personality, which had been formed since childhood, led him to slowly go into the abyss. After killing his adoptive father with his own hands, he began his journey of revenge.

What did Li Tieer suffer in the orphanage? What kind of people did he meet? So that he formed that kind of personality.

Or maybe he was not so bad in the orphanage, but the hellish torture in the United States later made him full of hatred for this society.

He wanted to destroy everyone who had brought him disaster, and he did so.

Xu Yao had no choice but to come to the United States to investigate with Mo Xiaoqing today. Although they had already found out that Li Tieer was the manipulator behind the scenes, and there were also photos.

But unfortunately, they could not find anything through the system entered in China.

Moreover, China's current DNA database is not perfect, and the data in it are generally the data of citizens with criminal records.

Xu Yao also asked the US police about this, and Li Tieer did not leave any DNA data in the United States.

From the investigation in the next two days, Xu Yao only found out that Li Tieer had attended a junior high school near the town, and then went to high school.

Later, a few days after Li Tieer's adoptive father disappeared, he also disappeared.

Moreover, Li Tieer's life trajectory stopped in May 2008.

After that, there was no identity information of this person. It was as if he had disappeared from the world.

Xu Yao asked the police station in the United States, how could a person completely disappear in the United States?

After all, the citizen information system in the United States is already very complete.

The US police said: No matter how complete the information system is, there is always a way to crack it. If a person wants to change his appearance and start a new life, it is actually not difficult. He can change his identity or face in the black market and continue to live.

There is another possibility. After Li Tieer disappeared, it is very likely that he did not stay in the United States, and he may have gone to other countries.

After three days of hard work, he was stagnant and a clue was cut off.

This made Xu Yao very annoyed, but at the same time he was powerless. All he could do now was to buy a plane ticket and return to Kuala Kangsar. Even though he knew that Li Tieer killed his adoptive father, he couldn't find out where Li Tieer was now, and he couldn't prove that he was involved in the behind-the-scenes manipulation.

On the way to the airport, Xu Yao's face suddenly turned pale. He held his forehead and half leaned back in the driver's seat with his eyes tightly closed.

When Mo Xiaoqing saw this, she asked anxiously: "Captain Xu, what's wrong with you?"

"It's nothing, just dizzy. It may be because the car is shaking so much." Xu Yao squeezed out a few words from between his teeth and tried to smile at her.

Beads of sweat broke out on Xu Yao's forehead, and Mo Xiaoqing immediately asked the driver in front to slow down and stop.

"Captain Xu, wait for me! I'll go get some medicine with you, and I'll also buy you some food."

Xu Yao replied weakly, "No need for food, I have a stomachache now, go get me some stomach medicine."

Xu Yao said weakly, leaning back in the car seat and closing his eyes to rest.

After getting off the car, Mo Xiaoqing hurriedly looked around with her eyes, although her English was not good, but she still recognized the signs.

Finally, she saw a drugstore on the corner of the street. Mo Xiaoqing rushed over. When she arrived at the front desk, she was stunned to find that she was speaking Chinese to a girl with blue eyes and green hair:

"Hello. Please find me some stomach medicine and headache medicine."

The American girl was naturally confused. She looked at Mo Xiaoqing with a sweet smile on her face, but her head was shaking like a rattle.

Mo Xiaoqing immediately took out her mobile phone, found the Chinese-English translator, and typed in the words. The front desk clerk finally smiled and nodded, and directly recommended four or five kinds of medicine to her.

Mo Xiaoqing typed a few more words, "Quick and effective."
