The operation went so smoothly that everyone was very happy.

But this joy only lasted until the next day.

After interrogating Feng Jianguo, everyone gathered together for a meeting with furrowed brows.

Captain Yu frowned and said, "Now Feng Jianguo only admits to stealing gold and silver jewelry. He has already confessed that it was left by his former employer. He secretly dug it out after they escaped, intending to keep it for himself."

But he absolutely refused to admit to killing Feng Weikun. As for the briefcase, he only said that he saw others had them and was envious, so he secretly used the items in his suitcase to exchange for money to buy it. After buying it, he found it difficult to take out, so he put it back in the suitcase to hide it.

The others fell silent after hearing this. Logically speaking, his reasoning wasn't entirely wrong, but it just felt a bit far-fetched.

After all, judging from his actions, Feng Jianguo is a cautious person; otherwise, he wouldn't have kept his secret for so many years without ever using the contents of the box.

But now, if someone is so fond of a briefcase that they're willing to risk buying it and not even be able to use it, what's the point of buying it? To collect it?

This statement just doesn't make sense!

But they also had no evidence to prove he was lying.

"There's another thing. The Revolutionary Committee somehow found out about our actions and wants us to hand over the people and things, saying that this is their responsibility."

After the police chief found out, he stopped Feng Jianguo on the grounds that he hadn't escaped suspicion yet, but he couldn't stop him for long. "We must find evidence as soon as possible to prove that he is the murderer, otherwise..."

He didn't say what he was going to say next, but everyone understood. Otherwise, it would not only have been a waste of time, but the Revolutionary Committee would have benefited from it.

For a moment, everyone's expression turned sour.

Seeing that everyone was silent, Captain Sun thought for a moment and said, "Don't rush. Since we can't find any evidence to prove that he is the murderer, let's try to recall things bit by bit and see if we can figure out anything that is wrong. After all, once something is done, it will definitely leave a clue."

Everyone thought it made sense, so they all perked up and took out the information they had collected over the past few days to read through it bit by bit.

"First, let's talk about motives. If Feng Jianguo really did kill the person, then what was his motive?"

"Because of revenge for being sold out back then?"

Zhou Yan thought for a moment and said, "Didn't Xiao Su find out back then that he was sold by Old Madam Feng? It's one thing to say how hard it is to be a servant, but wouldn't it be even more infuriating to find out decades later that the Feng family made their fortune from the money he earned selling himself?"

Captain Yu shook his head after hearing this. "We thought so too before, but during the interrogation yesterday, Feng Jianguo said that although the Feng family sold him, the family that bought him treated him very well. They not only let him go to school with the young master, but also taught him a lot of things."

Otherwise, he wouldn't have gone to work in a chemical plant later, where even ordinary workers couldn't just go.

Therefore, he did not hate the Feng family because of this, and his behavior after recognizing them showed that he did not seem to hate them.

Everyone thought about it and agreed. They had heard that Feng Jianguo would visit the Feng family during holidays. If they really hated him, they would want to never see him again.

What could be the situation?

The office fell silent again...

At this moment, Su He looked at the notes in the small notebook in her hand again, trying to find some clues.

Then, she suddenly noticed something they hadn't paid attention to before.

"What could have caused Feng Jianguo to leave the Feng family in a huff before Old Madam Feng died?"
