"Okay, then tell me what you think, I'll listen. But I can't guarantee anything!" Li Chu nodded and said.

"Brother Chu, do you think there are two people in this world who look exactly alike?"

"Yes, twins, and they have to be identical twins."

Sun Jianjun didn't understand anything about one egg or two eggs, so he asked directly, "What if they aren't twins?"

"Huh? What do you mean?"

"It's like this," Sun Jianjun organized his thoughts. The cases they handled all needed to be kept confidential, even after they were solved. Therefore, he had to explain things as clearly as possible without revealing details of the case.

“I have a case on my hands. After a period of investigation, we have identified a suspect. Witnesses have also identified him as the suspect, but he has an alibi.”

This person had ample alibis for each of the time periods in which the incidents occurred.

"Didn't you notice his absence? Was it intentional?"

"Brother Chu, what do you mean by that?"

"So, is the alibi of this suspect you mentioned deliberately created, or is it something that was meant to be?"

"Oh, I see. Our investigation didn't find anything intentional or unintentional. There were three time periods when the incidents occurred. Twice he was working the night shift at the factory, and the other time someone invited him to drink."

"Didn't you check and find out he's a twin?"

"Yes, we asked everyone, from neighbors to the people who delivered the baby back then."

Hey, this is interesting!

"Did you mistake the witness you found for someone else?"

“It’s possible for one person to admit their mistake, but there were witnesses on all three occasions, and our separate identifications all pointed to him.”

"Wait a minute," Li Chu said, but as he listened, he suddenly sensed that something was wrong.

"Didn't you say you committed the crimes at night? How come there are always witnesses?"

"Oh, my bad for not explaining it clearly earlier. This witness didn't actually see him commit the crime, but rather saw him near the scene around the time the crime occurred."

"Oh," Li Chu nodded, "So it's not certain whether it's actually this person or not."

“It was already quite unusual for him to be there at three or four in the morning.”

"So early? Who were the witnesses?"

This question made Sun Jianjun hesitate for a moment. He thought for a moment and said, "I can't tell you what the witnesses do specifically, but these witnesses didn't find anything wrong."

"So how did you get to this suspect?"

As soon as he asked the question, Li Chu regretted it a little. Before the other person could say anything, he quickly said, "Fine, forget I asked."

Sun Jianjun smiled awkwardly. He came to ask someone something, but he couldn't say this or ask that. This was only because they were one of his own. Otherwise, he would have been told to go away and have some fun elsewhere.

"So, you've identified a suspect, and witnesses have confirmed it, but he has a solid alibi, is that right?"

"More or less, but we didn't take any action against him. All the investigations were conducted privately because we weren't sure if he was still online."

Li Chu nodded in understanding.

"Does this suspect you're talking about still have family members?"

"there is none left."

"Is he an orphan?"

"That's one way to put it, but his situation is a bit complicated. He only returned from a farm in the northernmost province of Heilongjiang seven or eight years ago."

"You mean his parents died on the farm, and he went there as a family, but came back alone seven or eight years later?"

That's how it is.

"Where was he born?"

He was born in Beijing.

"In other words, it's not certain whether the person who came back in 2007 or 2008 is the same kid who went to Heilongjiang Province with his parents back then, right?"

"Brother Chu, what do you mean?" Sun Jianjun stared at him with wide eyes.

“Jianjun, you actually understood.” Li Chu shrugged.

"That's right. The neighbors can only prove that the babies in his family were not twins when they were born, but they can't prove whether the baby is a twin now."

At this point, Sun Jianjun frowned again: "But Brother Chu, he looks quite like his father, they look like father and son, and his appearance is also quite similar to his childhood photos."

Li Chu waved his hand: "If it's just that their face shape and facial features are similar, that doesn't prove anything."

After thinking for a moment, he continued, "Does he have any other relatives? I mean, his father's relatives."

"His father should have a younger brother in Shanxi Province."

"What does 'should' mean? It means either it exists or it doesn't."

According to the files, his father had a younger brother in Shanxi Province, but it is unknown whether he is still alive.

"There is a way to check if your current suspect is the same child who went to Heilongjiang Province with his parents back then."

"What method?"

As soon as he asked the question, Sun Jianjun seemed to realize something and immediately asked, "Brother Chu, are you talking about that D-something A identification?"

"Huh? You know about this too?"

"It was published in the police newspaper, saying they used a very advanced technology when handling the case, but..."

"But what?"

"I heard it's very controversial, and many experts think it's unreliable."

"Whether it's reliable or not is not for them to judge. Although this appraisal cannot be used as evidence right now, it can at least provide you with a line of thought."

"Then, Brother Chu, how do you think we can use this technology in this case?"

"You need to find the younger brother in Shanxi Province first, and then do a kinship test between him and the suspect you are now. If the test shows that the two people are not related at all, then you will have to start the investigation again. However, there is a problem here."

"What's the problem?"

"That means if this person from Jin Province is not related to the suspect's father by blood, then..."

This back-and-forth confused Sun Jianjun so much that he raised his hand and pinched his brow.

"Brother Chu, it shouldn't be like that, right?"

"The probability is very small, but it's not impossible. However, if we do it, it will at least provide you with an idea."

Sun Jianjun looked around with a headache, only to realize that they had just walked around along the main road and were now at the entrance of the alley on the west side.

"Brother Chu, let me go back and think about it some more. My head is a bit of a mess right now."

"Okay, take your time. Come to the hospital to find me if you need anything."

"Okay, thank you, Brother Chu, for taking up so much of your time."

"What's the delay? I was just out for a stroll anyway. Let's go back soon."
