This case has been characterized by us as a robbery and homicide, and because the internal cameras of the bank were completely damaged, it is impossible for us to see through the cameras what happened at that time, and how the murderer killed the three deceased, everything, when we did not see the surveillance, is an unknown.

But for us, we know almost exactly what the murderer did to the deceased who was in the ATM by the way in which he died.

I checked the street surveillance of several other streets, but I was stunned and didn't see the suspect.

Therefore, I judge that the suspect's sense of anti-reconnaissance is very strong, and before he came to this street, he had already checked the monitoring blind spots and those places where there were no street probes.

At this time, Li Yan walked behind me and held an A4 piece of paper in front of me.

When I saw the map on this A4 paper, I glanced at Li Yan in embarrassment, and immediately said with disgust: "I said, if you don't write well, forget it, why draw a straight line, you are like drawing a dotted line?"

Li Yan glanced at me and said that it would be good to be able to paint like this, he is not Lin Yu, can he still paint me squarely?

As soon as I heard it, it also made sense, a man like Li Yan, who is five big and three thick, usually has nothing to do with boxing, and his biggest hobby is to fiddle with those Trojan horse software on the Internet, where can he draw.

Thinking of this, I immediately lowered my head and looked at this topographic map that Li Yan had drawn for more than half an hour.

The street where the bank is located is called Changyuan Road, with Shuangxi Road to the east and Huaxi Road to the west, and ground surveillance cameras are installed on these roads, so the murderer will not leave from these two roads, so there is only Nanxi Road south of the bank, which is under construction recently, so no vehicles will drive this way.

I think if I were the murderer, I would have chosen this path resolutely.

At the end of Nanxi Road is a four-way intersection, and surveillance cameras are installed at the intersection, so the murderer should take off his blood-stained military coat between the four-way intersection on Nanxi Road, and then pretend to be an ordinary person and swagger from this four-way intersection.

From the bank to the four-way intersection, there are a total of three alleys, and when the murderer left the scene of the crime, the military coat on his body should have been stained with blood, although this road is under construction, but at this point, there are many people who will be greedy for convenience and walk on this path.

In order not to attract the attention of passers-by, the murderer should take off his military coat in the fastest way, and the military coat cannot be found, so he should have walked into the alley closest to the bank and took off the blood-stained military coat.

According to this sketchy map, the alley that the murderer is most likely to enter should be.

I put a red mark on the side of the alley, then got up and got out of the van, and two minutes later, I came to the entrance of the alley, because it was very dark, and there was nothing lit in the alley, so when I looked over, it was pitch black.

I turned on my phone flashlight and walked inside, and when I went deeper, I found that there was a trash can here, and when I opened the trash can, a smile curled into the corner of my mouth.

In fact, the greatest sense of accomplishment in doing this line of work is that what I have deduced has been confirmed, I have always been obsessed with this feeling, this time is no exception, I took out the thick military coat from the trash can, and when I touched the military coat with my hand, the blood stains had already solidified on the coat, making the touch of the coat make me feel very disgusting, because now the whole coat is stiff, like hanging on the balcony, more than ten days of clothes that have not been collected.

Along with this military coat, there was also a watermelon knife about 30 centimeters in length that appeared in the trash can, and the knife edge and blade were covered with blood.

I brought the two pieces of evidence I found back to the scene, when I went back, Fang Yuan was about to close the team, for this unexpected joy, everyone present was excited, after returning to the special case team, I told Fang Yuan, Su Mian and Li Yan all the things I had deduced before.

Eventually, we came to a conclusion on the definition of this case, a robbery and murder case.

Cases like this are not uncommon in China, almost every year at the end of the year or the beginning of the year, there are a few cases, the murderer usually commits the crime in the evening or early morning, and the target of the murder is often some ordinary people who go to the bank alone to withdraw money.

But when the bank's ATM machine came out, it already had its own monitoring system, even if the murderer covered his face, we could rely on the character profile to simulate the murderer's facial features, so in a case like this, the police can almost solve the case within three days.

I took a look at the military coat that was placed on the table, this military coat is L size, generally speaking, the size of the military coat will be a few centimeters larger, according to the length of this military coat, it is just right for a person to wear one meter seven or eight, but when I saw that the skirt of this military coat was a little muddy, it made me suddenly realize.

The figure of the murderer should be between 1.65 and 1.7 meters, and the hem of this military coat must have just touched the heel or edge of the murderer's shoes, the city is in the rainy season, plus the road he left is under construction, not to mention the muddy, he wants to leave from that road, the soles of his feet must be stained with mud, and the mud on this coat should have been splashed between the alleys he left the bank and walked.

"1.65 to 1.7 meters...... Big brother, do you know how many people in this city are this height?" Li Yan sat on my desk and said to me helplessly.

I glanced up at Li Yan, and then said, "No, one meter six five to one meter seven, plus one deletion condition, left-handed." ”

"Left-handed, how do you know the murderer is left-handed?" Su Mian interjected.

I smiled, and then asked Li Yan to pretend to be the deceased, Su Mian pretended to be the murderer, Li Yan turned his back to Su Mian, and as soon as Su Mian opened the door, he pointed at Li Yan's right back with the ballpoint pen in his hand.

Su Mian was slightly stunned, and said that she knew, if the murderer was taken with his right hand, the most convenient way to kill should be to use a knife to directly stab the deceased's right back, not the left side.

"That'...... There are a lot of left-handed people, and even if the murderer is left-handed, like left-handed, it will not be recorded. Li Yan shrugged his shoulders and said helplessly.

"Hey, how can your special case team be lazy like this, and I still need to send the autopsy report in person?" At this time, Lin Xi's voice suddenly came in from outside the door, and I turned around to see that this little girl was holding a document at this time, with her hands crossed, looking at us with a look of disgust.

I was slightly stunned, then touched my head, took the autopsy report from Lin Xi with a smile on my face, and casually said why she came out with the autopsy report so quickly today.

The latter looked up at me and said how long it would take to die like this, and besides, she was going to have a month's vacation from tomorrow, so of course the matter at hand needed to be resolved as soon as possible.

When he heard Lin Xi say that she was going to enlarge the leave, Li Yan was also stunned, and said to Lin Xi suspiciously: "I said that Lin Da Forensic Medicine, in the entire forensic world, you are a workaholic, I remember that you haven't taken a day off since you came in, what's wrong, you suddenly want to fall in love?"

Indeed, since I entered the police force, I have never heard of Lin Xi having a break, this suddenly has to rest for a month, for a busy industry like ours, it is simply unimaginable, even if Lin Xi wants to please, the above will not approve, to put it bluntly, forensic medicine and we are a common relationship, as long as there is a homicide or forensic identification, no matter where she is, she must come back, plus the recent forensic hospital manpower is really insufficient, as soon as Lin Xi leaves, there are only two forensic doctors in the entire forensic hospital.

So I'm very puzzled, why did the above give Lin Xi a month off.

"What's the matter, your boss is merciful?" Seeing that Lin Xi didn't speak, Li Yan immediately asked.

The latter raised his eyes and glanced at me, and then said lightly: "I took annual leave, and I told Lao Li Tou, he didn't give me leave, I resigned, Lao Li Tou has no choice, by the way, I just heard from you that this case has progressed? What left-handed?"

Li Yan touched his head, and immediately said openly: "We have simulated the height and characteristics of the murderer, the murderer's height is between 165 and 170, and he is still left-handed......"

I frowned, glanced at Li Yan for a moment, and then coughed a few times.

Rules are rules, favors are favors, no matter how good the relationship is, if it is not the case-handling personnel, we cannot disclose the facts of the case to anyone.

However, today's Lin Xi has some contrasts, no matter how complicated the case is, no matter how inhumane it is, in the past, she was just doing her own job, and never crossed the thunder pool, but today, she took the initiative to ask about the progress of the case, which was a little surprising to me.

Unlike the forensic doctors on the TV series, the forensic doctors are very busy every day, in addition to the autopsy, they also have to test and test, and even the autopsy report needs us to go to the forensic hospital to get it or send it to us directly, so the forensic doctors in the criminal investigation industry will definitely not intervene in any case, because this is not their job, they are too lazy to take care of it, and even if they intervene, our police will not reveal anything to them.

Although it is a common profession, it is a rule after all, and it cannot be broken.

Lin Xi seemed to understand what I meant, and then nodded, and said that you are busy, and then turned around and walked downstairs.

"Go on, I'll go down and see. After saying this, I also followed Lin Xi's footsteps and walked down the third floor.
