Chapter 243

Jiang Yuan put on his duty uniform and walked vigilantly to the right of Wei Zhengguo.

To Wei Zhengguo's left was Wen Ming, his eldest apprentice, who was specifically called over.

To the left of Wen Ming was Mu Zhiyang, his youngest apprentice, who also rushed over specifically.

The current configuration of this four-person group is the same as the configuration of the old hunter Jiang Yuan met that day with Wu Longshan.

The difference is that none of the four are carrying guns this time.

Xu Taining had arranged a team of armed police nearby, and another team of special police was also armed, but the ordinary police officers were not equipped with guns.

On one hand, the command center's research and judgment determined that the killer's combat capability wasn't very high. There are no young people in Fang Jinxiang, so it's highly likely the killer is middle-aged or elderly, and there are no signs of him possessing weapons.

In addition, the primary purpose of this case is to find Liu Jinghui, so even if the police officers were carrying guns, their first choice would be to capture him alive.

Since that's the case, carrying guns is just asking for trouble.

In fact, under normal working conditions, police officers are not willing to carry guns either.

When police catch people, they always rely on numbers; to put it in high-EQ terms, "Even if the opponent is only one person, we still go in as a squadron," and to be blunt, it's usually, "The opponent is only one person, everyone go together!!"

Wei Zhengguo called Wen Ming and Mu Zhiyang over, thinking about relying on numbers.

The premise is being able to catch the person again.

With such a big case this time, as long as we can squeeze a drop of water out of the killer, it's an immediate third-class merit. If we can squeeze a bit more, we're heading straight for a second-class merit.

Wen Ming and Mu Zhiyang were both very happy to hang out with Jiang Yuan, and their eyes were also vigilantly watching their surroundings.

"Let's start from the intersection again." Wei Zhengguo crossed the street and knocked on the nearest printing and stationery store. When someone came out, he smiled warmly and said, "Boss, we have a few more questions we'd like to ask you."

"Haven't you already asked everything?" The boss looked at the four police officers in uniform at the door and muttered unhappily, but still let them in.

"Boss, do you have a driver's license?" Wei Zhengguo asked with a full smile.

"I do."

"Show us your driver's license." Wei Zhengguo could get the corresponding information by reporting the ID number or scanning the face on his police terminal, but he still wanted to see the store owner's actions.

Jiang Yuan watched from the side, more in a state of learning.

Investigation or interrogation has techniques; if it's an ordinary criminal police team member, the first two or three years following a master are spent learning these things.

Wei Zhengguo is quite good at this. When he was young, he caught thieves at train stations and bus stations, and caught robbers in urban-rural fringe areas; as long as they weren't caught on the spot, it was basically done through investigation and reports.

At this moment, Wei Zhengguo watched the movements of the boss opposite him, while the corner of his eye still had room to pay attention to the others in the store.

Unlike other shops in the township, the boss and employees of this printing and stationery store were generally young, in their thirties or forties, which counts as the top-tier "fresh meat" of the township.

The boss's driver's license also looked fine.

Wei Zhengguo checked it and asked, "Where is the car? Can we take a look?"

"It's parked in the backyard." The boss said.

Wei Zhengguo immediately moved to the backyard.

In fact, it was normal for the killer to encounter some accidental situations during the dismemberment process.

During the Chinese New Year in the countryside, killing a pig, even a butcher who had killed pigs for a lifetime didn't dare to say he wouldn't have any accidents.

Not to mention the killer's psychological pressure was great, the operation location was often not very comfortable, the line of sight, etc., were all restricted, and it was very normal to have accidental situations. Some killers even learned to wear latex gloves, and as a result, the gloves were cut into the corpse.

For the first three corpses, Jiang Yuan didn't find particularly useful evidence, but looking at the appearance of the fourth, Jiang Yuan hoped to have gains.

He didn't check the corpse in order either, but followed his heart, first taking large bones to flip through.

This look was more than an hour.

During this period, other forensic experts also came to look at the bones, but everyone's focus was different, and the direction of attention and judgment was also different.

Jiang Yuan watched silently, looking all the way to the cut radius and humerus, and couldn't help but stop.

What attracted him this time was the cross-section of the bone.

The bone was sawed open with a saw. This was nothing new. Many dismemberers liked to use saws, including Wang Guoshan in the reservoir corpse-disposal case, who also used a saw for dismemberment.

Compared to dismemberers who used axes, knives, etc., using a saw to dismember consumed less effort, the number of dismembered pieces was more, and the average weight of each piece was smaller.

Jiang Yuan could also be considered to have seen many corpses dismembered with saws, but for the fourth corpse source, its cross-section had changed.

What kind of change?

Jiang Yuan took out a few sternum and ribs to compare with the humerus and radius. At this time, one could find that the former's cross-section was flatter and smoother, while the latter not only had relatively serious cutting marks but also obvious jumping saw marks. In addition, the step marks of the humerus and radius were obvious, the distance from the cross-section was 4 millimeters, and the length was also 4 millimeters, while the sternum and ribs were flatter and clearer.

All these explained one problem: the killer changed the saw.

Regardless of whether he cut the sternum first or the arm first, he changed the saw.

Perhaps a saw was broken, perhaps a saw blade was broken, perhaps he felt the saw he was using wasn't powerful, regardless of what the reason was, in short, the killer changed the saw or the saw blade during the process of dismembering the corpse with a saw.

But regardless of changing the saw or the saw blade, it further indicated an answer: the killer completed the dismemberment at a fixed location.

The reason for such an inference was that the saw used by the killer must be a high-power saw, highly likely to be a chainsaw. The size and weight of the chainsaw were not small, and its saw blade should be called a saw chain, which was a heavy thing weighing several jin similar to a bicycle chain. Jiang Yuan felt that a normal dismemberer shouldn't carry two chainsaws, or a chainsaw plus another chain.

If the dismemberer had a chain breakage phobia, then with his rigor, directly changing the chainsaw to a new saw chain wouldn't be more reasonable and appropriate?

This thing was often used to saw wood and trees, and it was made of special steel. Sawing hundreds of knives, it could be sharpened and used again, and it wasn't that easy to break or damage.

Buying a new one online and changing it, after sawing two people, it might be possible to return it to the boss.

Therefore, in the fourth corpse source, changing the saw or saw blade, the more reasonable explanation was that the killer dismembered the corpse in his own territory.

Only then would it be smooth and easy to change the saw or saw blade when encountering problems.

If this was the case, it overturned another hypothesis, that the killer deliberately carried crime tools like a saw and implemented the crime in a place far from his residence or workplace.

In other words, the killer's residence or workplace should be near the crime scene.

That was near the residence of the third victim, Feng Xiaoyan!

Jiang Yuan thought of this point and immediately called Huang Qiangmin.

Huang Qiangmin on the other end didn't rest either, listening to Jiang Yuan's reasoning with expectation, but was slightly silent.

"Is there a problem?" Jiang Yuan felt it wasn't right.

"The motorcycles in Fangjin Township have already been swept by us, and no suspect has been screened out." Huang Qiangmin sighed.

Jiang Yuan was a bit surprised: "Swept so quickly? Then?? Around Fangjin Township? Villages relatively close to Feng Xiaoyan?"

"It's also possible. But motorcycles aren't used as much here as in Zifeng Town." Huang Qiangmin paused and said: "Could it be that they rode over from other townships twenty or thirty kilometers away?"

"A bit far. And, carrying a chainsaw on a motorcycle is enough of a struggle; carrying two chainsaws, or carrying one chainsaw and two chains? Too tiring."

"That's true." Huang Qiangmin stopped for a while and said: "It's also possible that Feng Xiaoyan moved, but the possibility of her leaving dozens of kilometers alone is indeed not great."

Huang Qiangmin said, and denied himself.

"Having said that, the probability of the killer being in Fangjin Township or the surrounding area is indeed very great. It's a pity that the other corpses can't find the corpse source, otherwise..." Huang Qiangmin was a bit annoyed, and then said: "Regarding the dismemberment tools, we have also been paying attention, but there have been no discoveries. En, your discovery is still very valuable, I will report it to Xu Chu, and still have to strengthen the search and investigation here."

Jiang Yuan responded and hung up the phone, also feeling a bit exhausted.

It was said that the scope was narrowed, but the scope of a radius of ten kilometers, or a radius of fifteen kilometers, was also not small. If there was enough time, then checking bit by bit, the possibility of gains would be great.

It was just that investigation was the most time-consuming. ===== CHAPTER 242 =====

Wei Zhengguo then said, "Then tell me, around your neighborhood, whose family has a motorcycle that hasn't been asked two or three times?"

The shop owner looked left and right: "Who can't afford a motorcycle these days? You might as well just ask door-to-door."

"We've basically asked door-to-door." Wei Zhengguo added, "If you find anyone we missed, tell us, and we have rewards too. Verifying a motorcycle is worth at least 5,000 yuan."

This is equivalent to a bounty for clues; the county bureau can issue relevant information.

The shop manager grumbled for a long time, and just as Wei Zhengguo was about to leave, he suddenly said, "I know someone who lends motorcycles to others; does that count?"

"You're talking about Boss Tang from the repair shop on the street, right?" Wei Zhengguo was becoming familiar with the surrounding environment.

"You know?" The manager gave an unhappy "en" and said, "You can't find who he lent the motorcycle to anyway, so why look for anyone?"

Jiang Yuan listened and looked at Wei Zhengguo.

Wei Zhengguo said calmly, "There's a ledger. The motorcycles there are all lent to customers; if guests come to repair their cars and don't have a car to use temporarily, they borrow from his shop so as not to delay their work. The service model is similar to luxury car shops, just with much lower prices."

Jiang Yuan nodded in understanding and immediately added, "Let's go check him first. A lot of people borrow cars."

The four of them quickly finished the inspection of this shop and then rushed to the repair shop without stopping.

The boss was a pot-bellied fat man; just looking at his image, he didn't seem capable of long-term body disposal.

If this were a serious killer, he should have built up his body to some extent. Killing is a high-confrontation activity, and looking at the boss, who weighs over two hundred jin, winning every confrontation and remaining fair-skinned and uninjured, that would be too much like a martial arts novel.

Wei Zhengguo raised his eyebrows at Jiang Yuan; there was a reason he didn't make this shop a priority for interrogation.

"Then let's mainly look at the people who borrowed motorcycles." Jiang Yuan said.

"You've all looked at the ledger several times. Did you even take pictures?" The fat shop owner pulled a booklet from under the counter and placed it on the glass counter, letting them look for themselves.

Jiang Yuan flipped through it roughly and used his document examination skills to check it.

It was just a running account of car loans, not frequent, about a few times a month.

This shop doesn't just do repair business; there's also a garage for car washing and a workshop for repairs. The rented motorcycles are just a small project, totaling three, sitting lonely in the corner.

"Are there any car borrowers not in the ledger?" Jiang Yuan asked, his question no different from before.

The fat shop owner said very calmly, "Basically, they're all in the ledger, and besides, it's impossible not to record those who borrow and return them twice."

Jiang Yuan nodded and continued flipping through the accounts.

A booklet was about to be finished, and just as Jiang Yuan was about to close it and return it to the other party, a term caught his eye.

"What does 'monthly fee' mean?" Jiang Yuan pointed to the small parenthesis after a number.

"It means monthly settlement." The fat shop owner said casually, "Old Fu from the power supply station has to run to the mountain area from time to time, so he gets a car from me, and he can get an invoice for reimbursement."

Without Jiang Yuan saying anything, everyone perked up.

"Why does he borrow a car from you?" Wei Zhengguo took over the questioning.

"He can't use a private car for public business. That's what he said, and he even had me issue invoices before." The fat shop owner said happily, adding, "Old Fu is a good person; every time he returns the car, he even washes it clean."

"Old Fu... where does he live?" Wei Zhengguo was getting excited.
