A member of the trace team said: "The notebook was completely shattered into pieces in the explosion, but there are still a number of fragments of varying sizes left at the scene. From one of the fragments, the fingerprint team extracted a right palm print."

This discovery made all the police officers in the room very excited. He Shenming couldn't wait to ask, "Is it clear? Enter it into the fingerprint database for comparison immediately."

"We did so, but found nothing." The police officer in charge of this area showed a helpless smile on his face,

"But I'll ask someone else to analyze it, and it should be a woman. But after checking the domestic DNA database, this person was not found."

"Could it be the owner of this palm print? She has no criminal record." A police officer guessed.

Xu Yao had another opinion, "Could it be that this woman is not from our country? In this case, there is no way to extract her fingerprints from the domestic DNA database."

Xu Yao nodded, "Your analysis is very reasonable. The DNA database in our country is not very complete yet, and not all residents' DNA has been collected. So far, the DNA database we have only contains the DNA information of some people, and the main source is the DNA of those who have committed criminal offences."

At this time, several police officers agreed to follow up. "We think this woman must be from abroad, because the suspect Li Tie'er was once adopted in the United States, so he must have a network of connections in the United States.

Although we haven't found Li Tie'er's whereabouts yet, it is very likely that he has infiltrated our country at some point in time and settled down with a false identity.

And now, he has begun to commit his crime. In this explosion, we can be sure that he has an accomplice."

Xu Yao nodded immediately and turned to look at He Shenming. Deputy Director He immediately understood.

"Okay, I will immediately send someone to contact the US police and ask them to cooperate with our work and send this palm print data to the US so that they can investigate their country's DNA database."

-

Two days later, in the morning, He Shenming held several data bags in his hand, pushed open Xu Yao's door very quickly, and threw the data bags in his hand directly on the table.

"The US gave us feedback. They compared the palm prints we sent over with DNA, and sure enough, someone matched the fingerprints above."

Xu Yao quickly opened the data bag, took out all the information inside, and looked at it carefully. Sure enough, there was a page of personal file information inside.

Wang Lina, whose English name is Lisa, is an Asian Chinese American. She is 23 years old this year. Both her parents have passed away. She grew up in a black community. Her father is the leader of a gang in that area.

Xu Yao looked at the information above and continued to translate as he read. He looked up at He Shenming in shock.

"This girl named Wang Lina used to be a thug in a Mexican drug dealer's lair. Like father, like daughter. She was influenced by him since she was a child and grew up to be a female gangster."

He Shenming couldn't help but sigh, "The Avenger YM really can't be underestimated. The accomplice he found is a ruthless character.

No wonder they managed to kidnap Yang Xuewu without anyone noticing despite having so much energy. In the end, we could only watch Yang Xuewu being blown to death by the bomb they tied."

After He Shenming sat on the chair opposite the table, he added, "The information I found this time may be very useful to you. Because I also found another clue. The police in the United States sent me all of Wang Lina's files and her life trajectory.

I found a group photo of her in high school."

He Shenming said as he took out the photo from the file bag, "This photo is a class photo at the graduation of a third-rate high school in the United States.

Look at the young man standing next to Wang Lina, he is also an Asian. Wang Lina affectionately held his arm.

Later, I found many photos of Wang Lina and this young man alone."

Xu Yao also turned his head to look at the photo, and immediately felt that the young man's figure was very familiar, but his face was very unfamiliar.

He Shenming began to analyze, "Didn't you investigate Li Tie'er in the United States? Li Tie'er was in the second grade of junior high school when he disappeared from his adoptive father's house, and his adoptive father also disappeared at the same time.

When you went there, you found a body in his adoptive father's house. The US police have confirmed that the body is indeed Li Tie'er's adoptive father. The US police further investigated and found that Li Tie'er killed his adoptive father and then disappeared.

Then within three years, the station The young man next to Wang Lina suddenly entered this community, and then he and Wang Lina were almost inseparable, and they went to school together in this extremely chaotic high school. "

Xu Yao interrupted, "Master, you mean to suspect that the young man next to Wang Lina is actually Li Tieer, right?"

He Shenming nodded meaningfully, "That's my guess. It's just that their faces are completely different, but now With the advancement of plastic surgery technology, you can create any look you want."

Xu Yao was very excited after hearing this and asked, "Then Master, have you found out any NNA information left by the guy next to Wang Lina?"

He Shenming frowned and shook his head helplessly, "I found out that the guy's English name is him and his Chinese name is Park Changhai. His file shows that he is a Korean American. Park Changhai's file says It shows that his grandfather came to the United States very early and then settled down in the United States. Park Changhai has half American blood.

I looked at Park Changhai's old photos and his high school photos and compared them. It is indeed very imaginative. "

Xu Yao stood up and walked back and forth in the room. Finally, he just said, "If we want to know the truth, we have to go directly to meet this Wang Lina."

At this time, someone knocked on the door of Xu Yao's office.

Xu Yao shouted, "Come in."

It turned out to be Mo Xiaoqing, who opened the door and brought in the information Xu Yao wanted, and put it directly on the desk.

She just glanced at the desk and saw the three words "Wang Lina" written on a piece of paper. She couldn't help but mutter,

"Wang Lina? Lisa?"

She couldn't help but glance at the photo next to it. She thought she was seeing things. Wasn't this the friend of Li Tianfeng who had dinner with her a few days ago?

Mo Xiaoqing was full of doubts. Wang Lina was Li Tianfeng's friend, so how could her photo appear on the desk?

She couldn't help but look at the data again. The upper right corner was marked with the US police data.

Mo Xiaoqing turned around and said to Xu Yao, "I know the person in this photo. Her name is Wang Lina."

The other two people in the office were shocked.

Deputy Director He and Xu Yao said in unison, with shock in their eyes, "What did you say? Do you know Wang Lina?"

"Yes, not long ago, I met her when Juanzi and I were buying clothes in the mall. Wang Lina is Li Tianfeng's friend. We had some minor frictions at that time, but we resolved them later, and finally we had dinner together.

Captain Xu, what's wrong? How did her photo appear on your desk? Could it be..."

Mo Xiaoqing suddenly remembered that it was definitely not because of personal matters that she appeared on Xu Yao's desk.

As expected, Xu Yao answered affirmatively, "Do you know who the fingerprints we got on the laptop screen at the Yang Xuewu explosion site came from? It was Wang Lina.
