After investigating the bar where Meng Na was, a little sister told him that when Meng Na left, she did carry a small white leather bag, and she did not wear a necklace that day, but she had a white gold diamond ring on her right hand. Pen, fun, pavilion www. biquge。 info

Wu Long later checked a surveillance video at the entrance of the hotel, which the bar itself had installed to monitor the entry and exit of the bar's door. It can be seen in the video that Mona was carrying a bag in her right hand when she went out, as if she was leisurely, until she walked out of the video screen, there was no one next to her, and there was no suspicious person.

Wu Long repeatedly replayed the video of Meng Na walking out of the surveillance screen, thinking in his heart that Murong Fei did not find the bag at the scene of the corpse, and even the ring in his hand was missing, which was obviously a robbery and murder case.

Thinking of this, Wu Long felt a little worried, robbery and murder were the most difficult, the murderer and the deceased were not familiar, and if he wanted to dig out the murderer from the deceased's relation, this door had been closed, and to remove the deceased, to find the murderer in the vast sea of people was like looking for a needle in a haystack.

He suddenly thought, the murderer found such an alley to commit the crime, it is also ingenious, there is no monitoring installed before and after this alley, there is no need to worry about leaving a picture when committing the crime, it seems that the criminal is more familiar with this area, carefully selected the place of the crime, and for the robbery target bar girl, it is estimated that there is also a certain pertinence, because the bar girl generally likes to wear expensive jewelry, and has more cash income every day.

The reason why he thought of these was because Wu Long thought of an important plan, in Wanzhou, there are some street robbery cases every year, and he wanted to find common ground by combing through past cases to obtain information on possible joint investigations.

At this time, the sky was already bright, Murong Fei and Su Yi were still dissecting the corpse in the dissection room, Murong Fei had been standing next to the corpse's head for half an hour, he had already shaved off the hair on the corpse's head, and his bare scalp was completely exposed in front of him.

While checking the stomach of the deceased, Su Yi asked, "Murong, hasn't the strike tool been decided yet?" ”

Murong Fei frowned and said, "Metal tools can be settled. ”

"That's not bad either."

"But just knowing about metal doesn't help much in the case."

"This form of damage is too complex, and it is really difficult to determine which tool it is."

"No, it's because of the complexity that I'm interested in this tool, at first glance, the shape of the contact surface of this tool is complex, but there are still certain characteristics, for example, I found that this tool has at least one plane, and there are other forms, but because the skin tissue is beaten to pieces, I really can't think of what it looks like."

"Since the skin tissue has been broken, it means that there is a bulge on the plane you mentioned, will this bulge leave marks on the skull below?"

"yes, I'm confused, I've been trapped by this skin, and I should continue to dissect it."

Murong Fei cut open the scalp of the deceased and separated the skull that had been shattered, and he was surprised to find that there were several obvious abrasions on the skull.

"I see that these scratches are parallel lines, no, there are some arcs, oh, I remember, it is really the tool I am most worried about."

"You already have an idea?"

"Yes, I had some ideas when I was on the scene, but I couldn't find these parallel curved lines, isn't this the mark left on the skull by the thread blow?"

"A tool that has both planes and threads?"

"yes, when put together, isn't this just a wrench?"

"Great, it looks like a wrench can cause this kind of damage, but who would carry a wrench with them?"

"Yes, the wrench is easy to wave, but it is not conducive to carrying, there must be a package, otherwise it will attract attention in the hand."

"That said, do you think it has something to do with the murderer's profession?"

"It's hard to say, generally speaking, the murderer will choose tools that are easy to get around him as the murder weapon, maybe it is really related to his profession."

After solving this big problem, Murong Fei was in a much better mood, and the most troublesome thing about this corpse was the injury tool that inferred the injury.

Murong Fei knew in his heart that the robbery and murder case was a dead end for the investigation, and for the Criminal Division, maybe some items could be found at the scene that could be combined, but Chi Ming searched all the trash cans in the surrounding streets and alleys, but he couldn't find any valuable related items, and after he heard the news, his heart was cold.

It's good now, Murong Fei thought to himself, the striking tool he deduced was a wrench, which was a relatively special thing, if the case had not progressed, Wu Long would definitely ask him to merge the wrench.

As expected, Murong Fei had just returned to the office after the autopsy, and Wu Long called.

"Murong, I think this case is a bit troublesome, robbery and murder, do you think this can be decided?"

"I agree with you, robbery kills."

"I've had people sort it out on my side, and in the past few years, there have been more than a dozen unsolved cases of robberies against bar girls, and I plan to sort them out again to see if there is a possibility of merging."

"There must be conditions for merging, do you have enough conditions on hand?"

"Our investigation is only from the aspect of investigation, such as the time of the crime, the location of the crime, the target or something, if your criminal department can come up with something, it will be the icing on the cake."

"Yes."

"I knew that Murong could always get something out of the whole thing, and he wouldn't let me go out of the pot without rice."

"That's right, Mona has a head injury, I analyzed the blow tool, and at the moment I think it's a wrench?"

"Wrench?"

"Yes, that's what I think at the moment."

"That's so special, isn't it?"

"I think so too."

"The murderer is a car mechanic?"

"There are many people who use wrenches, and there may be one at home."

"That's different, this robbery murderer is not something ordinary people can do, I think this person probably uses a wrench a lot."

"Perhaps, but it seems that a single wrench can not solve a big problem."

"No, Murong, I have more experience in merging cases than you, like this murderer who used a wrench to commit crimes, if he did do a case before, he would probably also use a wrench to commit crimes."

"Right? I hope that some of the dozen or so cases you have sorted out have been committed with wrenches. ”

"I will retry these cases one by one, read the transcript first, and try to find the original victim if it is not clear, and ask again to see if the perpetrator has ever seen a wrench."

After the discussion, Murong Fei leaned back in his seat, and he was recalling Wu Long's words in his heart: "If he had indeed done a crime before, he would probably have used a wrench to commit a crime." ”

Suddenly, he remembered one thing, is it possible that the murderer may not only commit crimes in Wanzhou, but also in other cities, or even in other provinces?
