After sending the shop owner away, Zhang Bin and I began to do a careful inspection of the body.

From the tires to the watch, to the trunk, to the hood, and finally to the inside of the car, the vehicle was almost dismantled and inspected. Fortunately, the effort paid off, and after repeated inspections, two dead leaves were found under the gasket in the trunk of the final vehicle, and a little dark red substance on the surface of the dead yellow leaves caught our attention.

Considering that the car's paint is red, it may be possible that it accidentally splashed on it while spraying it.

Zhang Bin picked up the two leaves and looked at them for five or six minutes, and finally concluded that the dark red substance on them was not paint, but something else, most likely after blood clotting.

"Xiao Xu, I will teach you a trick today, the paint will become very hard after it solidifies and dries, and I saw that the dark red on the leaves is not stiff, from this point I can judge that the dark red substance on the leaves is not paint, according to my experience as a trace inspector for so many years, I feel that the dark red substance on the leaves is very similar to the situation after blood coagulation."

I nodded suddenly, took the leaves and looked at them for a few seconds and said, "I remember, in the insurance fraud murder case that happened last year, the murderer killed the victim in the underground garage, and the splattered blood droplets left on the white wall at that time were very similar to this one. ”

"That's right! I found that your brain has been very flexible recently, and you will be able to achieve great things in the future, and you will be the director of the Songhai City Public Security Bureau in the future, and I will also work for you at that time. ”

I was embarrassed to be praised by him like this, scratched my head and said: "Brother Bin, don't talk about me like that, I haven't worked for a year, how can I ask for the position of director of the Public Security Bureau, and that position can be sat on by ordinary people?" ”

Zhang Bin put away his joking face and said with a serious face: "As long as you dare to think and work hard, even if you can't reach that position at that time, you will not be far away, and at worst you will be the captain of the criminal police team." ”

I nodded as if I didn't understand, and although I didn't quite understand the meaning, I thought it made sense.

Zhang Bin and I returned to the police station in advance and handed over the leaves to Ma Zhiyuan, who asked him to help thoroughly identify the dark red substance suspected of blood on it, and if it was blood, compare it with the DNA of the deceased.

Sun Jianguo learned the news, and personally urged Ma Zhiyuan to speed up the progress of the work, deal with the results as soon as possible, and at the same time did not forget to let people thoroughly investigate Wang Yongjun's various deeds, from the date of birth to the time of his disappearance, what he had done, where he was, and who he had grudges with.

Under the powerful intelligence system of the public security system, Wang Yongjun's life information was found out, and that night, Sun Jianguo's desk was messed up with a bunch of documents, all about Wang Yongjun.

"Vice Captain, it's been almost a year since the man disappeared, although we suspect him, how can we arrest him?" Zhang Bin also finished reading the document, put down the last document in his hand, he rubbed his temples and said.

Sun Jianguo didn't think about it and said, "Keep checking!" Let the bank help find out where Wang Yongjun used the bank card, and at the same time, let the telecom company help check the call history and last call location of Wang Yongjun's phone card. ”

"That's okay, I'll let people implement it, I hope Wang Yongjun doesn't have any clues left." Zhang Bin said and got up and pushed the door away, but I have some doubts that there are still people in the bank at this point.

At about eight o'clock that night, Ma Zhiyuan personally sent the test results to the office, and I saw that although his face was full of exhaustion, he couldn't hide the excitement in his eyes.

"Vice Captain, because the sample on the leaves is too small, it is difficult to extract a valid sample, but fortunately, there are not a lot of dark red substances, and after I have repeatedly tested it four times, I finally got the results out."

Sun Jianguo was also very excited, but seeing him like this at this time, he calmed down, took a sip of tea and said: "Seeing that you are so excited, there is no doubt that the dark red substance on the leaves is blood, and it is still the blood of the victim, right?" ”

Ma Zhiyuan said with a bitter face: "Can you let me say such exciting news, otherwise I feel that I have been busy for most of the day." ”

Sun Jianguo immediately didn't calm down, put down the teacup and scolded: "Don't talk about your fucking nonsense, hurry up and tell the result, if you don't say it from your mouth, even if I guess it's not solid." ”

Ma Zhiyuan said with a smile: "The hard work pays off, after my many efforts, it was finally determined that the dark red substance on the leaves belonged to the blood stains left after they dried up, and through DNA identification, the blood on the leaves belonged to the victim." ”

Hearing this, I let go of my hanging heart, now the blood found in the car belongs to the victim, so the murder suspicion of Wang Yongjun, the owner of the car, has skyrocketed, even if he is not the murderer, at least he is involved in the entire murder case, such as transporting the body.

Now it's time for the news from Zhang Bin's side, if there are clues, it is only a matter of time before Wang Yongjun is caught.

Sun Jianguo sat back on the chair, breathed a sigh of relief and said: "It's finally a bit eyebrow-raising, and it's worth the busy work of the past few days, and when this case is over, I'll give you a few days off to rest." ”

At noon the next day, Zhang Bin walked into the office staring at two dark circles under his eyes, still carrying a document bag in his hand. glanced at it in a daze, walked in front of Sun Jianguo, yawned and said: "Deputy captain, I have found the information you want, the last time Wang Yongjun used his bank card was on the 11th of this month, in a county town in southern Anhui. ”

"And the telecommunications company also found a little news, Wang Yongjun's phone card has been deactivated in April last year, but the call records before the investigation have been found, from January to March last year, Wang Yongjun and the two numbers have frequent contact, and one of the numbers has been shut down on March 17 last year, which coincides with the time of the victim's death, I suspect that the number that was shut down is the victim's number."

Zhang Bin said and took out a wad of papers from the file bag, I walked over and picked up a few and looked at them, there were call records from telecom companies, and there were also bank accounts.

Carefully comparing several phone bills, I found that Wang Yongjun had dozens of call records with two numbers in southern Anhui in January last year, and I continued to look at this situation, and found that one of the numbers was shut down on March 17, and a line of small print was remarked at the bottom of the bill, and the names of the owners of the two numbers were written. The owner of the number that was shut down on March 17 was called Feng Bin, and the owner of the other number was called Xia Zhiqi.
