Lin Su had been standing by the supermarket stairs for more than ten minutes, and she had been looking at the external structure on the second floor. After reading the report that Du Minshan rushed out overnight, Lin Su felt a little strange, and searched for the appearance of something in his memory, and always felt strange in his heart, so he came to the scene of the crime again.

At this moment, the supermarket is so quiet as if nothing has happened, and if there is either a cordon, it is a supermarket that is temporarily closed.

As soon as she got out of the car, Lin Su walked to the stairs on the outside of the second floor of the supermarket, she didn't go upstairs, she just stood below and looked at the top.

She found the windowsill mentioned in Du Minshan's report and imagined how the murderer had turned out of the windowsill.

According to the results of the report, a footprint was found on the windowsill that was not that of the three victims, and the toes of the footprints rushed towards the house, that is, it was likely that the murderer had left footprints left by the murderer who had entered the house through the window. Everything seemed to make sense, and Lin Su's first reaction when he read the report was the same, but when he arrived at the scene, Lin Su was beating a drum in his heart.

The outside of the window sill is more than 3 meters above the ground, and there is no support to climb on. If it was really as Lin Su imagined, how did the murderer climb up?

In any case, this footprint is likely to have been left by the murderer, and the owner of this shoe must be found!

Lin Su gave an order and asked his subordinates to check the model and style of this shoe, which stores in the city sold it, and who sold it.

The problem of footprints, just wait for the results for the time being, and another tricky matter is spread out on the table and has to be solved.

It's the unknown firearm.

Lin Su knew in his heart that this gun was the key to the whole case, and if he found this gun, it was very likely that he would lock on to the suspect. Judging from the scene, the murderer may have been a veteran with a gun, although two shots did not hit the victim, but the other three shots were killed by one shot, and the other two shots should not be missed, but to deter the victim, or other purposes.

No firearms were found at the scene, and the murderer with the gun was very dangerous, and every minute that he was not arrested would pose a threat to the people.

There are very few people who can use guns, and unlike in the United States, guns are weapons to protect themselves.

So what is the identity of the murderer?

A huge mystery hung over Lin Su.

At this moment, the ringtone of the mobile phone interrupted Lin Su's thoughts.

"Hey, well, Zhao Guoguang is here, right? Okay, you let him come directly to the scene of the crime, I'll wait for him here. ”

Lin Su sighed, he forcibly arranged a person for himself, and he had to accept it, although he was short of people now, but he couldn't want everyone, right? At least let Lin Su meet for a while.

The feedback from above to her was: this is an order.

Later, Lin Su inquired on the side and learned that Zhao Guoguang was maliciously transferred to the police station because he was suspected of being the deputy director of the local taxation bureau because of a case, which was ten years. This return to the criminal investigation team can be regarded as a measure for the public security system to examine its own problems and attach importance to outstanding colleagues.

Lin Su, who had no choice, could only accept such a result peacefully.

"What's wrong? When I saw you, I was sad? Du Minshan's voice sounded.

Lin Su wondered, how did this comrade who stayed up all night come to the scene? "Why are you here? Didn't you say you were going to sleep all day? Don't let anyone bother you? ”

Du Minshan smiled and replied: "I originally planned to do so, but when I was lying in bed, I didn't feel sleepy, and I really couldn't sleep when I had something in my heart." ”

"I said you should pay attention to your body, you're only a few years older than me, and your white hair is all over the place."

Du Minshan touched his hair and smiled.

"Did you find anything?" Du Minshan asked in a positive voice.

Lin Su shook her head, although she had a series of assumptions in her heart, but without evidence, she would not say it as a fact.

"Have you read my report? What do you think. ”

"Two key clues: guns and footprints, the problem of guns, have asked the firearms department to check the bullet marks, see what kind of gun, where it came from, along this line should be able to lead to a series of information. Footprints also sent someone to check the specific style of shoes and the source of sales, but I am not optimistic about what information can be found in the clues of shoes. ”

Du Minshan nodded, agreeing with Lin Su's point of view, after all, a shoe may make thousands of pairs, and finding a suspect in it can be said to be looking for a needle in a haystack.

As they spoke, they walked up to the second floor and into the office.

The victim's body had been placed in the morgue, and at the moment only the outline of a white line represented the existence of a lost life.

Du Minshan walked to the safe, half-squatted, stared at the half-opened safe, and said: "There is another question, I haven't thought it clearly until now, what is the murderer's motive?" What exactly is the purpose of the bullet marks on this? ”

He touched the bullet mark gently, hoping it would speak for itself.

Lin Su also had this question, "The most important thing now is to confirm the identity of the male victim and what is in the safe." ”

What's before an empty safe?

"Dangdangdang" There was a slight knock on the door, and a young police officer stood in front of the two of them and saluted a very standard salute, Lin Su couldn't help but laugh, thinking that this must be a child who had just graduated.

"Report to Team Lin, we've contacted the owner of the supermarket."

This is good news, last night Lin Su asked people to try to contact the supermarket owner, and he may provide a lot of useful information.

Lin Su had an unconcealable smile on his face, and then asked, "What about the others?" When can I come to the police station to assist in the investigation? ”

The young officer's face showed embarrassment, and he lowered his head slightly, and said, "The supermarket owner is not in the city, and he didn't say when he will be able to come back." ”

Disappointment was written on the faces of several people. Du Minshan turned his head and asked Lin Su: "Can't you force the inquiry?" ”

Lin Su shook his head, saying that the supermarket owner was not a suspect, and there was no way to force the other party to come back, if it was okay to say it in the city, all he could do now was to wait for him to come back.

"Still, I got a valid message." The young officer continued.

"The supermarket owner heard that there was a murder in his supermarket, and according to our description, the male victim was probably the supermarket manager, Ma Ming."

Lin Su immediately asked people to verify the identity of the victim Ma Ming. A supermarket manager, a part-time college student at a supermarket, and a college student who came to find friends. What is the purpose of the murder that happened in such a small space as a supermarket?

A rush of footsteps sounded outside the door, a slightly chubby figure flashed into the office, and a man with a smile on his face strode towards Du Minshan, grabbed his hand fiercely and shook it. While holding it, the mouth was not idle:

"Oh, Team Lin, right? I've heard of your prestige for a long time, and I often hear your name in my small county, which can be said to be a beacon in the criminal investigation system. It's an honor for me Zhao Guoguang to have the honor to work with you this time. Don't worry, I will definitely work hard and live up to the trust that the organization has placed in me! Hahahaha"

Zhao Guoguang complimented for a while, and his eyes kept glancing at Lin Su next to him, thinking that the female police officers under the Lin team were really beautiful, and they could be models without being a policeman.

Du Minshan was taken aback by Zhao Guoguang's actions, and after listening to his compliments in the clouds, he knew that he regarded himself as Lin Su.

Pulling out his hand, he said lightly, "I'm not Team Lin." ”

"That ......" Zhao Guoguang, who was at a loss, looked at Du Minshan, only to see Du Minshan's eyes glancing at the female police officer next to him.

Zhao Guoguang screamed in his heart, didn't he slap the horse's hooves! onclick="hui"
