Solving the case: Wu Song travels back 97 years and becomes a detective

Chapter 68 Changing Direction

"We'll ask you one more time: has there truly never been any relationship problems between your son-in-law and your daughter?"

"No! Definitely not!" Li's mother shook her head and said firmly, "They haven't even had a fight in all these years, so what relationship problems could they have? Besides, they often come to my house for meals, and I haven't noticed any difference between them since before."

"Okay, then contact us if you suddenly think of any clues!"

"Take care, officers."

……

noon.

Wu Song returned to the branch office and, after learning that Xu Bin was still chatting with the three lawyers from Beijing, took the opportunity to meet the three lawyers in the interrogation room.

Ah!

There was no black mist on his body.

It shouldn't be the real killer who swapped murders with Qian Hao.

Having confirmed this, Wu Song withdrew.

in the afternoon.

Everyone sat down together for a case analysis meeting.

"If he really did leave the poker table at 11 p.m. on the 19th, then there is only one flight that could get him back to Gotham City before 3 a.m., which is to first go to the neighboring Golden Fields, and then take a car back at speeds of over 100 kilometers per hour. We even went to Golden Fields to investigate, but there was no record of Qian Hao flying there, and all the flight attendants on the flight said they had no recollection of him."

"He must have really come back by train!" Gao Dahua took a puff of his cigarette, gave Wu Song a look, and gestured for Wu Song to speak.

"After being questioned again, Qian Hao accurately recounted what happened on that train."

"Could it be that those three lawyers from Beijing told him after they met with him?"

"Then unless the lawyer is his accomplice and took the train that day, in the same carriage that Qian Hao's ticket was for, but..." Xu Bin took a deep breath and shook his head, "According to my questioning of those three lawyers, after Qian Hao left that night, none of the three of them left. They called another person to continue playing cards, and they played until the next morning."

When they met Qian Hao at the detention center, the three of them met together.

To reiterate, unless Qian Hao manages to bribe all three of them, but then another question arises: how could he possibly bribe three people? Secrets are crucial! Even one person might not be able to keep a secret, let alone three; the matter simply cannot be concealed.

"So this kid was clearly on the train, but deliberately didn't say so, just to create a stir for himself. Those three lawyers must have been caught in his trap too." Ma Dazhi grinned. "It was definitely him, but he didn't do it himself. Was it a hired murder? Or what Xiao Song said, an exchange of murders?"

Ma Dazhi's gaze lingered on Wu Song's face.

"I still think it's highly likely that it was a murder exchange," Wu Song said immediately. "Although there's no scientific basis for it, I trust my judgment. Qian Hao has killed people himself, and he must have killed someone the moment I saw him that day."

Since, according to our investigation, he personally took the train back, he probably didn't have time to kill the perpetrator to cover it up.

There is only one explanation: in the agreement between Qian Hao and the murderer, Qian Hao first helped the other party kill someone, and then in the early morning of the 20th, that person helped Qian Hao eliminate his wife, Li Hao, thus completing the exchange of murders.

"What was the motive?" Liu Shutong raised her hand. "The couple had a very good relationship. It was just as he said, for the money?"

"The two of them don't seem to be short of money," Cao Dahua said. "Although they both like to gamble, I looked at their bankbooks, and Qian Hao's name is on them. There's over 100,000 yuan in the bankbooks! That's quite a lot of money! They're not so much in debt that they have to kill someone for insurance money. It's highly unlikely that they killed their wife because they were short of money."

It's worth mentioning that Qian Hao bought the accidental death insurance for the couple two months ago, which is a major reason why we believed him when he said he killed his wife to collect insurance money.

It seems that something might have happened to Qian Hao two months ago!

"I think it's a matter of feelings!" Xu Bin said after thinking for a moment. "There are only a few reasons for murder. Murder for money can be basically ruled out in our case. Murder for revenge, but the two of them don't seem to have any deep hatred for each other. So, that leaves only murder for love?"

It must have been that one of them cheated on the other, which led Qian Hao to decide to kill.

Investigate! Go through all their relatives, friends, colleagues, and mahjong partners again. One reason is to see who can provide clues, and the other is to see if there might be a murderer among them who swapped kills with Qian Hao.

As he spoke, Xu Bin's eyes drifted towards Wu Song.

If among these people is the murderer who killed Qian Hao's wife, Li Hao, then it would be safest to have Wu Song take action.

Find out who the murderer is, and then conduct a microscopic investigation around them.

This is far better than a large-scale investigation where everyone is suspicious.

"My master and I will handle this." Wu Song nodded, knowing what Xu Bin meant. "However, I suspect there's little chance the killer isn't among these people."

Qian Hao dared to provoke us so much. As an associate professor teaching criminal law, he shouldn't have been unaware that we would judge that he might use the method of exchanging murders.

But he did it anyway.

This shows that he has confidence in his network of contacts and is not afraid of being investigated.

Or even if we can find the culprit, the other party won't expose him. But I think the probability of that is probably not high. Can he guarantee that the person will grit his teeth and refuse to confess?

I think the former is more likely!

"Alright, let's investigate first!" Wu Song gave a wry smile. "Let's try to rule out his relatives and friends first!"

"Even if we can't find the murderer, finding some clues is good too," Cao Dahua said with a smile. "Disciple, with the two of us on the case, it will be a piece of cake."

"Haha! I hope so."

Next, Wu Song and Cao Dahua began to meet with each person in Qian Hao's network of connections.

After meeting, I looked at the person and asked two questions.

The purpose of this inspection is to determine whether any of these people are murderers.

The second question was whether they could provide any clues about Qian Hao and his wife's relationship, and whether Qian Hao had any debts.

He spent a week meeting with all the people who had social connections with Qian Hao.

In the end, the murderer didn't see it!

No clues were found regarding discord in the couple's relationship.

The only consolation is that I haven't heard any news about Qian Hao being in debt.

Therefore, his motive of simply defrauding insurance money is not very strong, which also proves that the direction of the investigation should be correct.

……

At the latest case analysis meeting, Wu Song reported his investigation results and then said, "I think we can change our approach to solving this case."

"What's your thinking?" Xu Bin asked.

"Since our guess is that Li Hao was likely killed in a deal with Qian Hao, and that Qian Hao killed someone for the murderer before Li Hao was killed, could we try to find out who Qian Hao killed?"

Qian Hao and his wife bought their accidental death insurance more than two months ago, and it was probably around this time that he conceived the murderous intent. We will now review the murder cases that occurred within the last four months and have not yet been solved.

I'm going to meet those suspects who are clearly highly suspected of murder, but who also have sufficiently strong alibis!

Let's see if we can first identify the murderer who swapped kills with Qian Hao.
