Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Chapter 359 This is a big case

Huang Jun nodded.

"It must have been because of water leakage. Wang Jian's father was in the house at the time and burned to death."

"Accident or arson?"

"At that time, it was determined to be an accident, and no traces of man-made arson were found."

Although seven or eight years have passed, Lao Huang is relatively familiar with the situation at that time.

"I'm an in-house officer and 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 burning was quite miserable. It was caused by the explosion of the gas tank. Later, the fire department inspected it and found that it was caused by improper use."

Cheng Zihao nodded. He did not doubt the results of the fire investigation.

Firefighters are professionals in this area. Since the investigation result is that the explosion fire was caused by improper use of the gas tank, it should not have been done intentionally.

"and after?"

"Nothing happened after that. Wang Jian and his mother were at his grandmother's house next door, so it was fine. Otherwise..."

The two chatted and went to the police station cafeteria.

Not to mention, the food at the Jianshe Road Police Station was good, better than the food at many police stations that Cheng Zihao had eaten before.

It’s not that the food is rich, it’s just that it tastes 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 such a long time, I can't remember clearly. Besides, Huangzhou is so big, there can't be more than a few murders in any year."

Cheng Zihao thought so. He was a little nervous.

In other words, in the cities that Wang Jian walked through, it was normal for homicides to occur.

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 [-]th, seven years ago.

And the time when Wang Jian's house caught fire... was August [-], 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 there such a coincidence?
Cheng Zihao retrieved the files on Wu Qizhou's murder case and reviewed them carefully.

Wu Qizhou was 52 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 looked at this half fingerprint, but there is no way, and they have not been able to successfully identify it."

An unfamiliar voice interrupted Cheng Zihao.

Cheng Zihao turned his head and saw a middle-aged policeman standing behind him. He was tall, round-faced, and looked kind-hearted. "you are?"

"Zhang Yu, field officer at Jianshe Road Police Station, the computer you are using is mine."

Cheng Zihao stood up quickly and saw that Zhang Yu 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 the lighter, lit it and handed it to Cheng Zihao. Cheng Zihao took out the cigarette himself, held it with both hands, and held it against 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."

"I can't help it. I have a backlog of cases from three years ago. I found some clues in the past two days, so I came to take a look."

"Is it related to this case?"

Zhang Yu pointed to the case of Wu Qizhou's murder on the computer screen.

"I'm not sure yet. I just read the file on this case and I feel it might be related."

"I was at the scene and followed this case for a while. Later it became a backlog and was handed over to the superiors. But if you have any questions, brother, I can help."

"That's great."

The files only record the objective circumstances of the case and some detailed information at the scene, but there are no detailed records of the investigation process of the case at that time.

For example, it is impossible to record in the files who the police officers involved in suspecting, what measures they took, and what they investigated. This information can only be known by asking the police officers who handled the case at the time.

"Wang Jian was actually a subject of suspicion back then."

After the two sat down, Cheng Zihao mainly asked about the scope of suspicion of the criminal suspect.

Wang Jian's father was burned to death, Wu Qizhou was a worker delivering gas tanks, and 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, after the house caught fire, Wang Jian and the others went to stay with relatives for a while."

"Where are the fingerprints? How's the identification going?"

"The fingerprints were found on the murder weapon, but the fingerprints were very badly broken. We asked experts from the provincial department to look at them, and they were also included in the fingerprint database. Unfortunately, they have never been identified."

The two chatted for a long time, and after exchanging contact information, Cheng Zihao greeted 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 dismemberment case that I asked you to help with last time..."

"There is half a fingerprint here. Can you ask Teacher Lu to take a look at it?"

"Okay, you send it over first and wait for my news."

Qin Yong can certainly handle the matter of identifying a fingerprint.

Fortunately, Lu Chuan has been busy in the laboratory these two days, so he can go and take a look.

Now surveying the laboratory below.

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 sure is him!"

The long-standing case from 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?
