Li Yi lost a lot of blood and turned pale, but he was still unambiguous when he scolded people: ", put everything away, who are you going to fight with?" ”

The gluten came up, his eyes rolled, and he lowered his voice and asked, "Brother Koi, is it the black hand under them with six fingers?" ”

Li Yi shook his head: "No." This matter is a bit complicated, so don't ask about it yet, and talk about it later. ”

I see that they are still entangled, thinking that now this bastard is really life and death, the eldest brother is injured like that, and he is still in the mood to discuss who did it, how big is this experience?

I opened my mouth and scolded, "You're not done yet? Li Yi, you can't afford to delay this injury, hurry up and go to the hospital! You have a fucking three long and two short, and Lao Tzu has to burn paper for you every year, are you annoyed?! ”

As soon as these words came out, a group of gangsters who were carried away by the blood suddenly seemed to be enlightened, their faces were murderous, and they asked about Li Yi's injuries.

Li Yi couldn't walk anymore, almost with his feet off the ground and being carried by the two younger brothers, he still commanded in his mouth: "Sandbag send me to the hospital, gluten, you take a few people to stay, and give Brother Ji and Brother Dao a hand." ”

Suddenly, a familiar voice came from behind us: "No need. ”

When I looked back, it was the old knife.

The old knife continued: "Stinky fish, don't fucking rub in, hurry up and go to the hospital!" ”

Li Yi had already been put into the back seat of the Jinbei car at this time, and this kid actually poked his head out of the window and said, "That turtle grandson shot quickly, it is estimated that he has practiced." Brother Dao, you really don't want my people to help you? ”

The old knife scolded with a smile: "This matter is not a vendetta and a fight on the road, what do you want your people to do?" Moreover, your sword brother is from the armed police, and ordinary three or five big men can't get close, so you're afraid of a bird! You don't want mother-in-law's nonsense, get the ball off the ball! ”

Li Yi still didn't give up: "I really don't want to?" ”

The old knife frowned and said: "I know what you think, don't you just want to be stabbed by someone and rush to take revenge?" Don't worry, your brother Dao won't let go of that grandson. ”

Hearing what the old knife said, Li Yi nodded and shouted to his subordinates, "Let's go." ”

The two cars started, one in front of the other, and drove away at a rapid pace.

Seeing that Li Yi was finally sent to the hospital, I breathed a sigh of relief, walked up to Lao Dao, and asked him, "How is the situation above?" ”

Hearing my question, the old knife shook his head: "When I went up, the person was already dead. This murderer, the attack is very black, and he cut Luo Xing's throat and carotid artery with a single knife, to be so accurate and ruthless, he must be an experienced veteran. ”

"For example, forensic doctors, surgeons, police officers, etc.?" I say.

The old knife nodded: "There is this possibility, but I am more inclined to another possibility......"

I thought about that, too, and we almost said in unison, "Serial killer!" ”

Thinking of this, I subconsciously moved to the back stairs of this abandoned small building of the Grain and Oil Bureau, I still wanted to see the scene.

Seeing that I wanted to go upstairs, the old knife didn't say anything, just followed me.

Although Lao Dao's criminal investigation experience is much richer than mine, our eyes and angles of looking at the case are different after all, and many times, I can see some things that Lao Dao ignores.

This small building has been abandoned for some time, a thick layer of dust has fallen on the corridor, the footprints up and down the corridor are very clear, and there is a line of blood stains ticking and ticking, so don't ask, it is Li Yi's blood, I will start with the footprints.

The footprints in the middle of the corridor are the most concentrated, and they are also the most complicated, and there is a clear line of footprints on the far right, but it must be an old knife, he has been a police officer for so many years, so that he can't even do such a small detail.

I also followed the original footprints of the old knife, step by step upstairs, while watching, while thinking in my heart: The people who have been up and down this building most frequently recently are Li Yi and Luo Xing, as for the murderer, he has just entered the building, and the footprints will be the freshest.

Li Yi was wearing a size 42 flip-flop with a rippled bottom, and the last time I saw Luo Xing, he was wearing leather shoes with small round toes, the size was about 41, and the shoes were a little old, so the texture of the sole should be not clear due to wear and tear......

My own shoe size happens to be 42, and a slight comparison with the shoe prints on the ground can find out the footprints of Luo Xing and Li Yi respectively.

As soon as this rule out, it is very obvious that the remaining two lines of very fresh footprints are the murderer's.

At the corner of the first and second floors, I found a relatively clear footprint and squatted down to observe.

Seeing me like this, Lao Dao introduced on the side: "This person's shoe print is the same as mine, it is a size 43, but you see, there is a shoe print of mine next to it, and if you compare it, you can see that his shoe print is slightly lighter than mine." This man should be about the same height as me, but a little thinner than me. ”

"You've been a little blessed over the years, and you're naturally heavier. This guy's body shape should be similar to the peak of your physical strength, and he is also very strong. ”

Hearing me say that he was blessed, the old knife snorted unhappily: "This footprint is nothing to look at, I have already seen it, the height and weight can almost be calculated, if you look at it again, what else can you see?" ”

I don't argue with the old knife either, because I seem to have discovered something else.

I landed almost my whole body on the ground, looked closely, and finally found what I was looking for on the ground.

I pointed at the thing and smiled at the old knife, "I can." ”

"Huh?" The old knife crouched down as well, and he picked up with his fingertips what I was pointing at—it was a tiny grain of clay.

"This is ......," the old knife carefully held the thing in the palm of his hand, and raised it to his eyes to look closely, "There is a little green thing on the soil-algae?" ”

"It's moss." I corrected.

The old knife paused, then reacted and blurted out: "Downpipe!" ”

"Yes. The building of Lin Sen's house sits in the north and faces south, the back of the building is shady, and the building is relatively old, it is normal for the downspout to leak a little, and it is even more normal to grow a little moss. If someone had ever climbed up or down the downspout of that building, they would inevitably get some of this stuff on the soles of their shoes. ”

The old knife's face became solemn: "This person is the guy you met in the parking lot, that's right." Twice he killed people under Lao Tzu's eyelids, but he really didn't take Lao Tzu in his eyes at all. ”

Although Lao Dao and I had long deduced that the person who killed Lin Sen, Fang Zhe and Luo Xing should have been committed by the same person, we had only guessed before, and it was not until just now that we got conclusive evidence.

The old knife took out a small plastic bag from his pocket, put the mossy clay in it, then sealed it and put it back in his pocket - although he had long since retired from the police, some habits were still the same, such as carrying this plastic evidence bag with him.

We continued upstairs.

When I was about to reach the third floor, there were fragments of mobile phones in the corridor, and there were traces of struggle in the corridor on the third floor, which were left by Li Yi and the murderer.

The door was wide open, and at a glance there was blood everywhere, and Luo Xing's body was lying flat on the ground facing the door.

I went to check the door first, and the old knife interjected, "There is no trace of forced entry." I still stick to my previous opinion - this murderer is very familiar with Lin Sen, Fang Zhe, and Luo Xing, but what I suspect is that among the five of them, there are still two people alive, Meng Rong has been identified as a co-perpetrator, could it be that the main culprit responsible for the murder is Liu Yao? I've seen Liu Yao's photos, and I don't believe this woman can have such ability. ”

As the old knife said, the door was intact, and there was no trace of forced entry.

"We were in such a hurry just now that we all forgot one thing." Lao Dao's words inspired me, I turned my head to Lao Dao and smiled, "Didn't Li Yi fight with the murderer, whether the other party is a man or a woman, what does he look like, don't you know when you ask?" ”

The old knife slapped his thigh and shouted aggrieved - such an important thing can be forgotten, it's really a premature life!

I saw him hurriedly touching his mobile phone in his trouser pocket and reminded: "Don't call Li Yi, his mobile phone is broken, do you have the phone number of his subordinates?" ”

The old knife glanced at me, I looked at him like this, he must have a number, so I didn't care about him, and asked him to call Li Yi, at this time, I happened to check Luo Xing's body.
