However, we lack more convincing evidence. Cao Fan frowned slightly, and his face was cold, "Because the deceased was injured by this, and the deceased was wearing clothes." ”

"So we couldn't have taken a sample of the deceased's dander on it, that is, there was no way to prove that this was the murder weapon that beat the deceased before he died. ”

There is some truth in Expert Cao's words.

Although the process of handling a case requires bold guesswork, all the exhibits and reports presented to court must not use the words of speculation, let alone present the guessed evidence in court.

Not only will it fail to convince the judge and jury, but it may also reduce trust in the right party.

Looking at the things in her hand, Qiu Lan lowered her eyes silently.

The hard blow of this thing can crack the bones of the deceased, won't there be anything left?

She remembers when she was on the construction site, and the clothes worn by the workers were all dusty and dirty, could she?

"Expert Cao, if all the ingredients on the construction site are tested on this massager, can you prove it?" Qiu Lan raised her eyes slightly, looked at the people on the side, and said in confusion.

"Yes, but when we found this before, we found that the massager had been cleaned, so it should be difficult to find. Cao Fan frowned and answered her question softly.

Did you just let the director go?

If this massager can directly prove that he has beaten the deceased, then it lacks a strong evidence against the supervisor.

Suddenly, she remembered a very crucial place, when the deceased was placed on the unplaning table, his body had been torn apart by the tremendous force of the impact.

Later, Qiu Lan spliced together for five hours to complete all the body parts, and because there were many scars, it may not have been reported that what was considered unrelated to the case at the time.

The deceased was working on a construction site and was often prone to injuries, and if he had been injured that day, he could have had wounds.

And if there is a wound, then the blow may come into contact with the blood of the deceased.

Because this thing has been cleaned, there is no blood visible on this massager now, but ordinary cleaning can only wash off red blood cells, platelets and other substances in the blood.

However, there is a special substance that will not be washed off by the flow of water, it will adhere to the object, and it will only fall off after a certain period of time or special treatment.

And this substance can be reacted.

"Officer Xu, Specialist Cao, I think I need to go back to the dissecting table and take a look at the other wounds that I classified as non-human scars and non-fall trauma at that time, maybe I will find important clues. ”

After a brief explanation, she left to solve the anatomy department, and also informed her assistant Xiao Cong by the way.

In the preparation room outside the autopsy room, Qiu Lan hurriedly changed into a surgical gown, and it happened that Xiao Cong also took out the body of Li Shoude, the deceased in the fall case, from the corpse parking room.

"I am Qiu Lan, a forensic doctor, and now I am going to conduct a second autopsy for the deceased Li Shoude in the fall case, case number: BR241377. After documenting the incident, she leaned down slightly and began to revisit the wounds on the corpse.

"There were four contusions on the right calf, one contusion on the left leg, three contusions on the left shoulder, no injuries on the right shoulder, and a contusion on the waist. ”

She started with the feet of the deceased, examined them little by little, and found nothing unusual.

So, with the help of her assistant Xiao Cong, she turned the deceased over, "There is a scratch on the right lower back, but it should have been caused a few days before death, there are traces of healing, and it is an old injury." ”

Suddenly, a small scratch came into her eyes, "There is a small scratch on the left shoulder blade of the deceased, it is a metal scratch, and there is coagulated blood in the wound, it should have been caused before death, maybe it will come into contact with the murder weapon." ”

"Xiao Cong, show me the scar under the ultraviolet light that day, I remember that there was a subcutaneous bruise here. ”

"Good. Hearing her words, the assistant Xiao Cong immediately took out the materials from the time in the file folder and handed them to her, "Doctor Qiu, there is indeed an oval scar. ”

"Great, then there's hope. Qiu Lan hooked her red lips slightly, and smiled at the corners of her eyes.

Just when a ripple of joy was set off in her heart, the light in the corner of her eyes suddenly caught a glimpse of the photo of the deceased on the file, and found something unusual, "Xiao Cong, give me the file of the deceased." ”

"Give. Xiao Cong handed her the file and asked suspiciously, "Doctor Qiu, have you found anything abnormal?"

"Hmm. Qiu Lan narrowed the corners of her mouth and nodded indifferently, "Look at his photos, do you find anything?"

After Xiao Cong took the photo, he wrinkled his brows and looked at it carefully, "The deceased's eyes were sunken, his face was black, and his lips were white, so he should have liver disease." ”

"Well, you're half right. Qiu Lan frowned with a heavy face, "When did this photo come about?"

"Photos?" Xiao Cong pursed his lips and thought secretly, "It was only after we finished dissecting the body that the serious crime team got the photos from the family and sent them, and then I washed them out and pasted them on the file for preservation." ”

"So that's the case, then this corpse is very problematic. Qiu Lan lowered her eyes meaningfully, "I think, we have to go to the place where the incident happened." ”

Because a murder weapon similar to a beating was found in the supervisor's office, and there was a confession from the foreman, Xu Chengyan invited the supervisor to the police station as usual.

"Officer, what are you looking for me for?" Director Zhang glanced at Xu Chengyan impatiently, his brows furrowed slightly, "I have already told you, that person committed suicide and has nothing to do with me." ”

"You've searched my office several times, and if you find anything, you'll arrest me, and I'll go to work to support my family. ”

Seeing that he was completely uncooperative, Xu Chengyan didn't say anything more, but directly took out the information from the previous investigation, "This is your account overseas, and there are regular remittances every month." ”

"You are really smart, through the stock market, directly launder the money overseas, do you know that we will not check in the direction of overseas when we check?"

"Officer, what are you talking about?" Director Zhang rolled his eyes in annoyance, and a touch of emptiness quietly slipped through his eyes, "This has an overseas account, it's normal, okay, I have investments overseas, so I naturally have an account." ”

"But what is recorded every month is not an overseas account, but a domestic account, or under the name of Qiu's Group, a foreman at a construction site pays for it. Xu Chengyan clasped his hands in front of his chest and stood beside him.

"So what can it be?" Director Zhang pursed his lips, "I work in the Qiu family, and it's normal to have dealings with the construction site." ”

"Normal?" Xu Chengyan snorted coldly, lowered his eyes, and then took out the massager he found in the office and threw it in front of him, "Okay, then you recognize this, are you familiar with it?"

"Officer, what are you doing? This is my massager, I have lumbar spondylosis. Director Zhang secretly crossed his legs and put it in, but he was still unkind.
