"The other thing is gasoline."
This was the fuel found at the scene that set the body alight.
In fact, there were no combustibles in the bathroom of the rental house. Tang Jun should have used some clothes when he destroyed the corpses and eliminated traces.
Judging from the results of the forensic autopsy, the other party cut open Wang Mengmeng's abdomen, stuffed some clothes inside, poured gasoline on it, and ignited it before burning the body into that state.
The results of Wang Zhaokai's interrogation of Liu Lingling also showed that there was no gasoline in Liu Ling's rental house.
"The gasoline Tang Jun used to destroy the body that day must have been brought by him, but he had no vehicle or motorcycle in Haizhou City. How did he buy this gasoline? Or was it obtained through other means, we need to find out this."< br>
If the other party brought his own gasoline to Liu Ling's rental, then it is possible that he was planning to murder someone, otherwise the other party would not have realized this thing.
Relevant investigations have pointed all fingers at Tang Jun, but the other party refuses to admit it, so what we need to find now is irrefutable evidence that Tang Jun committed the murder.
On the one hand, they are looking for the pair of shoes that Tang Jun once wore.
Although Tang Jun argued that the footprints left on the balcony and the roof were from a conflict between him and Wang Mengmeng and Zhang Lili a few days ago. He left it behind, but this explanation is not reliable.
Because even so, where are the shoes that Tang Jun left footprints on?
This is also the second place where Tang Jun is smart. The most important reason why he asked the police whether the footprints could be used as evidence was because of the pattern of the shoes. He did not have shoes with that pattern.
Zhang Luchuan knew that the other party asked this question because the other party was very confident that the police could not find the pair of shoes, so Tang Jun must have thrown away or destroyed the pair of shoes after leaving the scene of the crime.
It is unlikely to be destroyed. If it is to be destroyed or burned, there must be some traces.
Therefore, it is more likely that the other party will abandon the shoes when they go somewhere.
Of course, it is not particularly easy to argue now, because there are many different paths from the rental house to the hotel where Tang Jun lives, and no one knows which path they chose.
Therefore, we still need to do a comprehensive review of all the surveillance videos on the path from the rental house to Tang Jun's hotel that night. This cannot be completed in a day or two.
The two tasks were arranged, everyone assigned tasks, and then everyone went to work.
First, Wang Zhaokai arranged for Sun Biao and his team to investigate the source of gasoline and search all nearby gas stations.
If Tang Jun is really the murderer, then the other party's murder cannot be a temporary act.
Therefore, the time when the other party purchased gasoline should be earlier than the time of the crime.
According to Tang Jun, he actually went outside Liu Lingling's rented house that morning and saw Liu Lingling and Zhang Lili coming out, and then he followed them behind.
The reason why he and Liu Lingling wanted to talk to him alone about remarriage, but because Zhang Lili was always around, they didn't get a commission.
Although the police did not fully understand the entire process of Tang Jun following Liu Lingling, judging from the fact that Liu Lingling returned to the rental house alone at noon, Tang Jun did not follow her until noon.
In other words, Tang Jun should have been able to act alone at noon, so this time period was also a key time for Sun Biao and his team to investigate. Tang Jun has no means of transportation in Haizhou City, and he has never ridden a bicycle or motorcycle, so the gas stations he can reach should be within walking distance.
Sun Biao's focus here is to investigate the gas stations that can be reached on foot. There are 5 in total, and the distance from each other is no more than 2 kilometers.
The gas station is different from the rental house.
The surveillance equipment is very complete. Once you enter the gas station, you basically enter the surveillance area with no blind spots. Therefore, as long as Tang Jun really appears here, he will definitely be able to take pictures of the other party.
Chen Jiang divided all the members of his group into seven groups.
Taking the rental house as the center and extending to the hotel where Tang Jun lived, they cleared a total of 7 paths.
Some of these seven paths are very short, and some are slightly circuitous.
If it fails after research and judgment, it is believed that all seven paths may be chosen by Tang Jun, but the specific one cannot be confirmed.
Therefore, Chen Jiang sent 7 groups of people to visit and evaluate these 7 paths.
Most of the houses in this area are self-built and rented out. The population is relatively large, but at the same time, there are also many elderly people living here.
Therefore, the information collected through interviews and surveys is quite optimistic.
"No one passed this road at night. There were two people who rented in our building. I knew very well that I couldn't sleep that night. It was around 2 o'clock, so I took a shower outside and drank some tea. I didn’t go back to the room until five or six o’clock in the morning, so I knew very well whether anyone was here.”
Visits and surveys coupled with some monitoring and investigation can reveal some clues and eliminate some paths.
Two of the routes have been taken by the police. One was excluded because the surveillance showed very clearly. This surveillance was a privately installed high-definition surveillance. Three people passed by on the night when the crime occurred. All three of them were nearby tenants.
There was another path. There was an old man who couldn't sleep well. He basically sat at the intersection to enjoy the coolness in the middle of the night, so he was very sure that no one with a figure similar to Tang Jun passed by.
Although the other five paths did not make such clear exclusions, someone made a discovery on one path passing the pond.
"It was probably about two o'clock. I can't remember the exact time. Someone threw something into the pond, but I didn't see the specific thing. After throwing it, he left in a hurry. I thought he I don’t care much about the garbage thrown away.”
These are some situations seen by an old man scavenging, which provided important clues to the police.
Although this path was not the shortest path for Tang Jun to return from the rental house to his rented hotel, it was because he passed by a pond.
There are three ponds in the entire self-built house area, and this pond is the closest to where he lives.
Of course, the so-called ponds are originally smelly. In the past two years, the self-built housing area has been undergoing urban renovation. In order to improve the environment, the smelly ditches have been cleaned out and transformed into ponds.
It looks less managed, and the smell is at least not that bad.
But Father Time only saw a figure throwing something into the pond. He didn't see clearly what the figure looked like, and he didn't see clearly what he was throwing. (End of chapter)
