Chapter 359 This is a big case
Huang Jun nodded.
"It must have been a flood. Wang Jian's father was in the house at the time and burned to death."
"Is it an accident or arson?"
"It was determined at the time It was an accident. No trace of arson was found.”
Although seven or eight years have passed, Lao Huang is relatively familiar with the situation at that time.
“I’m a back-office worker and I shouldn’t have followed him out to handle the case, but I was familiar with Wang Jian’s father back then, so I went to the scene.”
“The burn was quite miserable, it was a gas tank. The explosion was later inspected by the fire department and was caused by improper use."
Cheng Zihao nodded, he did not doubt the investigation results of the fire.
Firefighting is professional in this area. Since the investigation result is that the explosion fire was caused by improper use of the gas tank, it should not be done intentionally.
"What happened next?"
"Nothing happened after that. Wang Jian and his mother were at his grandma's house next door, so it was fine. Otherwise..."
The two chatted and went Police station canteen.
Not to mention, the food at Jianshe Road Police Station is good, better than the food at many police stations that Cheng Zihao has eaten before.
It’s not that the dishes are rich, but they simply taste good. The braised pork with potatoes goes particularly well with rice.
"Brother Huang, when Wang Jian's father died, were there any cases in Huangzhou?"
"Case?"
Huang Jun thought for a while: "It's been so long , I can’t remember clearly. Besides, Huangzhou is so big, there must be a few murders every year.”
Cheng Zihao thought about it, he was a little nervous.
In other words, it is normal for homicides to occur in the cities that Wang Jian walked through.
However, they were all corpse dismemberment cases with similar methods, which made Cheng Zihao think that these cases were probably done by the same person.
After eating, Cheng Zihao used the computer again.
This time, he focused on the murder case in Huangzhou seven years ago.
One of them attracted Cheng Zihao’s attention.
Wu Qizhou, an employee of Market America Liquefied Gas Company, was killed seven years ago, but the case has not been solved yet.
What attracted Cheng Zihao's attention was not Wu Qizhou himself, but Wu Qizhou's occupation recorded in the file.
He is responsible for delivering liquefied gas tanks to residents in the Changjiang Road area. Cheng Zihao just visited Changjiang Road in the morning, and Wang Jian's home is on Changjiang Road.
In other words, Wu Qizhou gave Wang Jian’s gas tank seven years ago.
Cheng Zihao looked at the time when Wu Qizhou was killed, August 4th, seven years ago.
The time when Wang Jian’s house caught fire... was August 2, seven years ago!
Wang Jian's father was burned to death in the fire because of improper operation of the gas tank, and the worker who delivered the gas tank to his family was killed?
Is it such a coincidence?
Cheng Zihao retrieved the files on the murder of Wu Qizhou and checked them carefully.
Wu Qizhou was fifty-two years old when he died. He was single, unmarried and had no children. Both his parents had passed away, and only one brother was still alive.
The scene of Wu Qizhou’s murder was very tragic. According to the photos in the file, Wu Qizhou’s head was almost chopped off.
The murder weapon was found at that time, and it was the kitchen knife from Wu Qizhou's home.
The place where Wu Qizhou lived was very remote, with few neighbors around.
There was very little evidence found at the crime scene, only half a bloody fingerprint extracted from the murder weapon.
“Many experts have seen this half fingerprint, but there is no way, they have not successfully identified it.”
A strange voice interrupted Cheng Zihao.
Cheng Zihao turned his head. Standing behind him was a middle-aged policeman with a tall, round face and a good-looking appearance. "Who are you?"
"Zhang Yu, field worker at Jianshe Road Police Station, the computer you are using is mine."
Cheng Zihao stood up quickly and looked at Zhang Yu He was older than him. He took out a cigarette from his trouser pocket and handed it over: "Brother Zhang, I'm causing you trouble."
The other party took the cigarette, took out a lighter, lit it and handed it to Cheng Zihao. He took out the cigarette himself, held it in both hands, and held it to the flame.
He tapped the four fingers of his right hand gently on the back of the opponent's hand to signal that he was ready.
Zhang Yu took the lighter back and lit a cigarette: "Old Huang told me that you came from Liangzhou, which is not close."
"There is no way, in my hand There is a backlog of cases from three years ago. I found some clues in the past two days and came to take a look. "
"Is it related to this case?"
Zhang Yu pointed at the computer screen. The case of Wu Qizhou’s murder.
"I'm not sure yet. I just read the file on this case and I feel it might be related." I've given it to you, but if you have any questions, I can help."
"That's great."
The file only records the objective circumstances of the case and some details of the scene. , but the process of investigating the case at that time was not recorded in detail.
For example, who the police involved in the case suspected, what measures they took, and what they investigated are impossible to record in the file. Only by asking the police who handled the case at the time can they know.
"Wang Jian was actually the subject of suspicion back then."
After the two sat down, Cheng Zihao mainly asked about the scope of suspicion of the criminal suspect back then.
Wang Jian's father was burned to death, and Wu Qizhou was a worker delivering gas tanks. The two cases occurred very close to each other. It would be strange if Wang Jian was not investigated.
“But Wang Jian had an alibi at the time. His relatives and mother could prove that he was sleeping at the time and had never left his relatives’ home.”
“Oh, by the way, the house was on fire. Later, Wang Jian and the others stayed at a relative’s house for a while.”
"Where are the fingerprints? How was the identification?"
"The fingerprints were found on the murder weapon, but the fingerprints were very badly broken. Experts from the provincial department were also asked to look at them, and they were also included in the fingerprint database. , but it’s a pity that it has never been identified.”
The two chatted for a long time, and after exchanging contact information, Cheng Zihao said hello to Huang Jun before leaving.
Guest house.
“Brother Hao, where should we go next?”
According to normal procedures, the investigation on Wang Jian is actually over, and the team can return to Liangzhou.
Cheng Zihao smoked a cigarette and thought for a while: "Wait a minute, I'll make a call first."
Qin Yong's office.
"Zihao, what's the matter?"
"Brother-in-law, I'm in Huangzhou now, investigating a case, the corpse case that I asked you to help with last time..."
"Here is half a fingerprint. Do you think you can ask Teacher Lu to take a look at it?"
"Okay, you can send it over first and wait for my news."
Identification of a fingerprint , Qin Yong can certainly accept it.
It just so happens that Lu Chuan has been busy in the laboratory these two days, so he can go and take a look.
Now surveying the underground laboratory.
Lu Chuan completely completed the peeling off of more than thirty groups of superimposed shoe prints, and as the peeling was completed, the results were obvious.
“It is indeed him!”
The long-standing case four years ago has been solved!
But how did Wang Huifang’s husband get his colleagues to prove that he was not at the crime scene?
Is it a collusion?
