"Couriers, takeaway guys, censuses, door-to-door sales. Pen, fun, pavilion www. biquge。 info is not small just to meet the range of possible people who can knock on the door and enter the home. The egret shook his head with a wry smile. Girls in college towns like to shop online, firstly because it is far from the city, and secondly, the students are not wealthy, and most of them have limited living expenses. Therefore, the mode of online shopping is the most common mode of consumption in university towns.

There are a lot of express deliveries here, and there are at least a dozen of them.

There is also competition among the couriers in charge of the same area, and there are at least 2 or 3 people in shifts.

In other words, the two communities in an adjacent area not far from each other are likely to be delivered by a wave of couriers. Bai Li's speculation was not wrong. But there are also many professions that will also deliver door-to-door, and the mobile phone information and purchase information of the first deceased have been ruled out.

"Even if it's a repairman, it's not impossible to be an electrician. Zhou Qian also gave two answers.

"According to the dossier, the first deceased did not order a courier or order takeout before he died. According to the phone records, there were no repairs or needs for help in the home. The door-to-door salesmen in the neighborhood have all registered with the doorman. If you want to check, it's not a difficult task. "I don't think a murderer with such clean hands and feet would leave such a big void for himself. ”

Two sub-districts. Three homicides. It is indeed possible to say that these identity inferences before are true, but judging from the information exchanged by the deceased before his death, there is no overlap, and it is really far-fetched to say which of them is.

Besides, add shooting equipment and a tripod to the inference.

This thing is not small, no matter who holds it, it is very abrupt. In addition, professions such as couriers are basically occupations without rest, and if they can really abuse and sexually assault them for more than 20 hours in a row, they will kill people. At least one day was absent. In this case, it is a little too obvious.

This murderer is good at covering up traces, and with such an obvious loophole, he shouldn't fail to take precautions.

"Just to be on the safe side. Let's check the information of these people. The egret said to Zhou Qian, "One point is one point." ”

"The other party likes to look at the shape of the deceased *****, and this guy should be someone who has some research on this. Like photography, if you pursue harshness, you should be more serious in terms of personality, usually such people are not too bad people like, maybe more withdrawn. Let's start with this type. ”

The previous police investigations basically followed this routine. The profile of the egret has the help of Bai Li, a little more. But it's just a little narrower.

Time passed quickly, and even if there was an extra oil bottle Bai Li, the three of them still completed the on-site survey quickly.

The third crime scene also found the movement of furniture, and it seems that the other party is indeed a paranoid person who shoots and chooses scenes. Bai Li went through all the details of the house over and over again, but found nothing.

"If it's so easy for you to find clues, I'm afraid the criminal police in the college town will be unemployed. Bai Egret's words are not to be regarded as comfort or ridicule, "It's not too early, it's been a busy day, so it's better to go and have a meal first." ”

Zhou Qian stretched, she was already tired. "Whew, I heard that there is a good Korean barbecue here, so I just went to try it. ”

Bai Li had no objection.

The three of them summed it up and went straight to the Korean barbecue city.

Korean barbecue in the university town is one of the most popular restaurants here. It's cheap and varied, and it's crowded with people who come here every night to eat.

If it were a normal day, Bai Li would probably be excited to come here to eat. But just came out of the place where her best friend was victimized, and the nature of what the little girl did was not high. Just thinking about the murderer.

Sitting down in the restaurant, Zhou Qian looked at the heavy atmosphere and took the initiative to get the plate, leaving only the egret and the silent Bai Li.

"All three cases were premeditated, well-planned murders. Egret said with relief, "The clues on the bright side, the local police have also been following up." There is no hurry. ”

"I know. Bai Li snorted. Then he remembered something and whispered, "Thank you." ”

The egret was stunned, "Thanks for what?"

"Thank you for letting me follow the investigation. I know that this will probably have a bad effect on you. Bringing an outsider to participate in the investigation, even if there is a reason, is procedurally unjustifiable. Bai Li said slowly.

"Looks like you don't understand. The egret shook his head, "It's okay for a while. I also hope that you can provide some helpful information. After all, one person has a narrow mind, and three people have a wide mind. ”

"My uncle was also a criminal policeman. Bai Li said suddenly, "When I was young, my parents were very busy. I have always grown up with my uncle, who doted on me and even taught me to play with guns and told me about social cases. I have been interested in cases since I was a child. ”

"When I grew up, I also started to read some mystery novels. Study the dossier of a real-life case. My dream is to one day join the National Police Agency and become a murderer profiler. ”

"Oh, that's a lot of ambition. The egret smiled.

Murderer profiler is an emerging police profession, somewhat similar to high-end criminal investigation specialists. Most of these people are experts and professors who study criminal psychology and criminal behavior, and they all have the ability and ability to solve cases. Huaguo itself does not have the profession of case detective, at most it hires experts who are extremely strong in a certain aspect as consultants.

Especially in Shendu, an international metropolis, the National Police Department has even hired some experts in special fields, including theology, religion, literature, networking, psychology, etc. Will support difficult cases.

The special case brigade also has a very close relationship with these experts. As the most important case detection team, having its own think tank is also one of the magic weapons to win by surprise.

When Egret hadn't joined yet, the detection of some cases relied on these experts. After Egret joined, he almost synthesized the skills of these people, and rarely went far away in special cases. There is basically a tricky situation, and the old guy will be assigned to the third group of egrets to be responsible.

"Your powers of observation and association are good. To be honest, it's really suitable to be a criminal policeman. Egret nodded appreciatively, "It's just that it's not enough to think about it." Even if you're smart enough, consider whether you're capable of subduing the killer. Otherwise, even if you track down the murderer, you can't catch the other party, and even your life will be in danger. It doesn't make sense. ”

"Cut, nosy. Bai Li said disdainfully, "It's not that you have to fight hard." In today's society, we need to learn to use our brains. Can't I fight, can't I outwit it? In short, no one can stop me from avenging my friend!"

The egret spoke bitterly for a long time, but Bai Li didn't appreciate it.

After all, this little girl has not experienced any winds and waves, and her view of reality is still very immature.

At this time, superfluous persuasion is useless. No matter how much you say, people with firm minds will always have their own decisions, and no one can change them.

"Then again. If the killer is not a courier or similar door-to-door service person. Who else could that be?" Bai Li said confusedly, "Three schoolgirls who have no connection, close to each other, not far from each other. I can't think of anyone else who can reach out to three people at the same time. ”

"The truth is often simple. Egret smiled, "Although I can't identify the murderer in the case yet, I do know a truth. ”

"No matter what kind of crime it is. There is always a unique purpose. In my opinion, this case must have been committed by a man who needed to satisfy his sexual needs. ”

"You should also note that the place where the murderer last fiddled with the body is not the place where the deceased died. They were detained, abused, and sexually assaulted for 20 hours, either from the bedroom or from the bathroom, before being dragged into the living room to pose as corpses. ”

This shows that this man's social status is not high, and even his status is humble. If you want to satisfy your pathological desires, do you have the means to satisfy your desires, so you take the form of crime. ”

"That's what I thought, too. Bai Li said with a frown.

"A man with low self-esteem. But the male function is perfect. I don't usually get it, but I look forward to it. Bai Li's eyes gradually lit up.

"It also has to be timely. Egret continued, adding, "A profession that doesn't get a warning or leave even if you don't go to work for a day or two." ”

"A character who can dodge the few cameras. ”

"A guy who doesn't feel weird to anyone else wherever he goes, with a tripod and a camera. ”

"It's also possible that the other party put the equipment in the morning. The egret continued.

At this time, as soon as the cycle put the dinner plate away, she hugged at least 8 plates of meat, "What are you talking about?

"My God, you only eat meat, aren't you afraid of getting fat?! You still take mainly pork belly, can't you get some beef?" Bai Li sighed.

"I didn't see any beef!Also, if you're dissatisfied, take it yourself!I'm not your nanny!" Zhou Qian also looked at Bai Li dissatisfied. This little girl doesn't know the severity, and she calls her "aunt". Her anger hasn't gotten over yet.

"The beef is just under the pork belly plate, so easy to find. How do you have such an observation as a policeman, you are still playing with the lights when you are so old!I despise you!" Bai Li's mouth was willing to suffer, and the two actually began to fight over the beef issue.

The egret looked up at the ceiling speechlessly, and said that three women in one play, with the progress of the times.

Two women already have one, okay?!(To be continued.) )
