As a local policeman, is it appropriate for you to take over the job of a criminal policeman?

"Okay. We conducted a comprehensive examination of the deceased yesterday. The fatal injury to the deceased was a blunt object hitting the back of the head, which led to his death. The time of death was approximately between 5 and 6 pm the day before yesterday. In addition to the fatal injury to the back of the head, we collected some bruises on his face and other parts of his body, some old and some new. He must have been beaten before he died."

"There was also blood found by the river, which was confirmed to be the deceased's own. No other blood was found at the scene."

Forensic doctor Lao Zhang gave a brief report, which was similar to what everyone thought. At present, the forensic side is still relatively clear.

"That means the time of death was between 5 and 6 p.m., which was the time when Lin Xianhao met the deceased. As for whether it really happened after Lin Xianhao left, it's hard to say." Ye Lin said.

"Over here, what are the results of the on-site search?" Yu Haifeng turned and looked at the forensics.

"We searched the scene for evidence, and found a bloody stone in the nearby grass." The forensic expert projected a photo of a stone onto the big screen.

"After testing, the blood on the stone was found to be from the deceased. After comparing it with the deceased's wound, it was found to match the fatal wound on the back of the deceased's head. This stone was the murder weapon."

Ye Lin looked up and saw a photo of an ordinary-looking stone. If it was thrown into the river, it would be difficult to find it.

"Is this stone from the Songhe site, or was it brought from somewhere else?" Ye Lin asked.

"According to our testing of the stone, the soil and weeds on the stone are the same as the samples collected near Song River, so basically the murderer picked up this stone by the river."

Ye Lin nodded and signaled his colleague to continue.

"At the same time, we collected several sets of footprints at the scene. One set was the same as the deceased's feet, another set was the same as Lin Xianhao's, and we compared several sets. One set was from Lao Han who found the body. The other two sets were relatively clear, and both were about size 2 shoes. So we estimate that there should be 42-2 other men who went to the scene. We just don't know if they went fishing or the murderer's."

"If what Lin Xianhao said is true and he is not the murderer, then there must be a murderer among the remaining groups." Ye Lin interrupted.

"In theory, that's true, unless the murderer didn't leave any footprints at the scene," said the forensic colleague.

"What about the others? Have the surveillance cameras on the road or the fishermen on the other side found any clues?" Yu Haifeng looked up and asked.

"Captain Yu, there are too many cars on the road. We have only checked half of them so far. It will probably take another day," Zhao Jianfeng said.

There was no other way. Those cars would be parked by the river for half a day, so they had to look at them for a long time and they had to contact the owners one by one, which was very time-consuming.

"We have asked several fishermen here, but we haven't found the person Lin Xianhao mentioned yet. Most of them are concentrating on fishing and don't pay much attention to people coming and going. Plus, the location of Lin Xianhao and his friends is a bit far away from the fishing spot, so no one knows." Wang Longxin reported.

"We have also visited several fishermen on the other side of the river. They are a relatively fixed group. If what Lin Xianhao said is true, we should be able to find them," Sun Jinghua reported.

After everyone had finished speaking, Yu Haifeng looked at Ye Lin and said, "Linzi, please give us a summary. What suggestions do you have for the next step?"

Ye Lin's mouth twitched. Damn, he is getting more and more direct now. He just wants to do it himself no matter what.

"Then let me tell you." Ye Lin cleared his throat.

"Dead: Fang Rongjie, time of death: 5-6pm the day before yesterday, murder weapon: a stone from the river. The deceased received a call from Lin Xianhao at 3:25, then drove to the river, had an argument with Lin Xianhao, and then died."

"There are two possibilities for the murderer: one is Lin Xianhao himself. He killed Fang Rongjie out of hatred for his wife's affairs. This is easier to understand."

"There is another possibility, that is, Lin Xianhao was telling the truth. He beat Fang Rongjie and left, and then a mysterious third person killed Fang Rongjie. Of course, this depends on whether we can confirm the existence of this third person."

"So, what we need to do now is to find the person who went fishing that Lin Xianhao mentioned. If he can prove that Lin Xianhao did not kill Fang Rongjie on the spot, then we have to find this third person."

"Of course, if he saw the murderer directly, it would save us a lot of trouble."

After Ye Lin finished speaking, Yu Haifeng nodded and asked, "Then let's go find someone to find a car?"

The other people also looked at Ye Lin, waiting for him to tell them what to do next.

"In fact, have you ever thought about this question, that is, what is the connection between these two cases?" Ye Lin looked at everyone.

"I think the connection is that Xiang Sisi was murdered, then her affair was exposed, and then her husband Lin Xianhao killed her lover. Sometimes the case is just that simple." Lao Zhao's view on this case is relatively simple.

In fact, many cases are like this. They look complicated, but once the real truth is revealed, it is a very simple matter.

"Could the person who killed Xiang Sisi be the same person as the one who killed Fang Rongjie? Or two different people?" Ye Lin asked.

"Well, that's not necessarily true." Old Zhao was also a little confused.

The main thing is that the murderer who killed Xiang Sisi has not been found yet, and now another murderer who killed Fang Rongjie has appeared.

"Okay, Linzi, you go and investigate Fang Rongjie's case, and I'll take Lao Zhao to investigate Xiang Sisi's case. Then we can compare them together and see what the connection is." Yu Haifeng said.

Now these are two cases, and they are also related. We cannot give up on either one.

"Okay, Xiao Sun, come with me to find the fisherman. Xiao Wang, Sister Shan Shan, watch the surveillance."

After Ye Lin arranged the division of labor for everyone, he took Sun Jinghua and left.

According to the results of Sun Jinghua's previous investigation, the village on the other side of Song River is Liu Village. Most of the people who go there to fish are from Liu Village. As for outsiders, they usually go to Lao Han's side, which is the side where Fang Rongjie was killed.

There are only a few households that fish in Liu Village. Sun Jinghua has inquired and found out that there were about five or six people who went fishing there on the day of the accident. Sun Jinghua had already questioned three of them that day. The ones he wants to find today are the other two: one is named Liu Jinming and the other is named Liu Jiansheng.

Liu Jinming is in his 50s and works in the city. He rarely comes back home on weekdays. He only came back the day before yesterday on the weekend.

Liu Jiansheng is almost sixty years old and usually lives in the village in a semi-retired state.
