Chapter 344 Steel Hook
Lu Chuan believed that the reason why a local or someone who had lived there for a period of time committed the crime was simply the place where the other party dumped the body.
Although Lu Chuan has not been to the scene, according to the photos in the file, the part of the sewage river where the murderer dumped the body is not open-air. The section of the sewage river where the murderer dumped the body is an underground river, which is still some distance away from the open-air river. .
Had it not been for the dog kept by the cleaner, which bit through the box containing the body and took out a piece of the body, this case might not have been discovered at that time.
Thinking about it, Lu Chuan, who had nothing to do, took out the photos again and studied them.
However, after looking at it for a long time, Lu Chuan shook his head. There were no fingerprints, so it was really difficult to figure it out.
This kind of case is not easy to convict even if the murderer is found, because the police did not find any traces of the murderer at the scene.
It’s not that the murderer left no traces at the scene, but that the police who checked at the time didn’t find any.
For example, trace evidence. If trace evidence had been collected at that time, there should be some traces left.
Of course, the Liangzhou police did put a lot of effort into that year and used the three-piece criminal investigation kit to the extreme.
The on-site investigation even brought in foreign experts, but unfortunately, the environment in the sewage river was already poor, and many traces have disappeared.
The dossier records many details, including the sewage shaft near the place where the body was dumped, and even the traces on the iron ladder that went down to the shaft were collected during the current investigation.
The investigation was also very thorough. I basically searched the three kilometers around the body, but found nothing.
The last trick is to conduct surprise inspections of some local idlers, petty thieves and other people with criminal records or bad records.
But, again, no clues.
Lu Chuan held the photo and observed it repeatedly.
If the murderer is an outsider, it will be a problem whether he can find the entrance to the Liangzhou sewage river.
But if he was a local, how did he do it and dump the body quietly without anyone noticing?
While thinking, Lu Chuan was attracted by an inconspicuous mark on the photo.
The part of the body in the photo, which should be the biceps of the left arm, seems to have a special indentation, but it is not very clear.
"Master, come here and take a look at this."
Liu Guodong, who was chatting, turned his head: "Still studying it?"
"This case was quite famous back then, and many experts had seen it. , the experts from the province have also looked at it, it’s a pity.”
Lu Chuan nodded, the dismemberment case is an important case everywhere, and it is normal for the experts from the provincial department to have studied it.
Liu Guodong found the teacup and took the photo from Lu Chuan's hand: "Did you find anything?"
Lu Chuan pointed to the indentation on the body: "I feel like there is an indentation here."
"Indentation?"
Liu Guodong held up the photo to the light, and after a moment: "It seems that there is indeed one, but the body was packed in a suitcase at the time. There should be traces caused by squeezing inside."
Speaking of suitcases, the Liangzhou City Public Security Bureau almost sold the entire suitcase. I rummaged through the market just to find the same box that contained the body.
Last of all, I did find it, but the things in the warehouse were from the previous inventory and were not sold at all.
This also confirmed that the murderer came from out of town.
Lu Chuan thought for a while: "Well, it's possible."
"Okay, this case, Captain Qin's brother-in-law has heard that he is a powerful person, so he will take a look at it, take a rest, and change Change your mind, the High-tech Zone sent two fingerprints, please help me take a look."
"Okay, I'll take a look."
Putting down the file, Lu Chuan started to do his own work. .
Soon, the pleasant day passed smoothly.
Lu Chuan picked up Shen Yan and went on a date to watch a movie.
Today, the two of them watched Wall-E. Two dumb guys who couldn’t speak, explained what love is.
"Tomorrow we will go to the city bureau to participate in forensic skills training. We may come back a little later in the evening."
Before getting off the car, Forensic Doctor Shen talked about tomorrow's work: "You will come back by yourself in the evening. Don't worry about me. ""That's alright. I have nothing to do recently. I will pick you up at the city bureau tomorrow."
“Yeah, okay, see you tomorrow.”
“Yeah, see you tomorrow.”
Leaving Forensic Doctor Shen’s community, Lu Chuan hummed a little tune and drove back slowly Morning light community.
"Kawako, wait a minute, the sewer at the door is blocked, it will be fine soon."
At the gate, the entrance and exit were blocked by Lu Yao, and two workers were opening the manhole cover.
Lu Chuan got out of the car and took a look: "It's okay, Third Brother, I just want to chat with you."
"Haha, Chuanzi, in two minutes, they opened the manhole cover, and people went down and covered it. Put on the manhole cover and you're on your way."
After that, he handed Lu Chuan a cigarette and asked the workers to open the manhole cover quickly.
“Hold on tight, the car is waiting.”
Lu Chuan took the cigarette and was about to light it when he suddenly caught sight of two workers opening the manhole cover out of the corner of his eye.
The sewage manhole cover is very heavy and is set flat on the ground. It is impossible to lift it by hand. The worker uses a special iron hook to insert into the hole of the manhole cover and pulls hard, and the cover opens a gap.
In less than two minutes, two workers went down wearing overhead lamps, and people outside put the lid back on.
"Kawako, okay, you go over first."
"Okay, third brother, you are busy first, I will go back first..."
Um?
Iron hook? !
Lu Chuan's car, which had just started, screeched to a halt.
“What’s wrong Kawako, it’s okay, we can get over it now.”
Lu Chuan could not care less now, got out of the car in a hurry, walked to the worker who had just built the manhole cover, and pointed The hook in his hand: "Third brother, what is this?"
"It's just a steel hook, used to open manhole covers."
Open manhole covers?
“Do you use this tool to open manhole covers?”
Lu Chuan looked at the workers: “Is it just for us, or do you all use this tool?”
The worker was stunned. He didn’t know why Lu Chuan asked this, but he picked up the hook anyway: “This is used to open manhole covers. It’s the same across the country.”
"It's the same all over the country..."
Lu Chuan murmured to himself: "Show me."
The other party handed the hook to Lu Chuan: "Some of them sell this thing, and some of them make it themselves. , We welded this one ourselves, it is strong and durable."
Lu Chuan nodded, picked up the steel hook, and looked carefully at the end of the T-shaped hook.
This shape is very similar to the indentation on the corpse that Lu Chuan saw in the corpse case file this morning.
Liu Guodong explained that the indentation might have been left by the box containing the body.
Lu Chuan thought it was possible at the time, so he didn’t delve into it further.
However, it now seems that this indentation is most likely left by this T-shaped hook.
Based on the location where the murderer dumped his body and the sewage river, could the murderer be the local sewer maintenance worker?
Or at least someone with this kind of steel hook?
"Are this kind of steel hooks used in other industries?"
The maintenance worker thought for a while: "Generally not, this thing is only used when opening manhole covers, and it is not used for other... .”
