"So, you mean to say that the deceased was frightened and had a heart attack when he came into contact with the murderer, so he died suddenly. Xu Chengyan frowned and said in doubt.

"Yes. Qiu Lan nodded heavily.

"But, since you're dead, why do you have to hit it with a stone?" Xu Chengyan pursed his lips, and a look of puzzlement flashed in his eyes.

"I haven't figured that out yet. Qiu Lan pursed her lips and shook her head, looking thoughtful, "However, I also found a little white granular substance in the body of the deceased, and it was preliminarily determined to be a drug, but the specific test report still has to be waited." ”

There was a drug in the body, and the head was hit hard, why was the deceased stunned twice?

The case does not seem to be as simple as an ordinary rape and murder case.

"By the way, did you find any clues at the scene?" Qiu Lan said with a solemn expression with a heavy expression.

"Well, based on the moss you found on the wound, we found a nearby body of water, and we also found a blood-stained stone, which the forensic department has taken for testing. A pair of thick eyebrows in the room between Xu Chengyan's foreheads wrinkled slightly, as if they were shrouded in gloom.

"Also, we also found the deceased's bottoms there, and the tops are of the same brand, all sportswear, and I asked the people around me, and I said that the deceased often exercised here in the morning, and this morning is estimated to have come for morning exercises. ”

"But here's the suspicion, according to your inference, the time of death of the deceased was between four and five o'clock, but the morning exercise time is usually six or seven o'clock, and some witnesses also say that the deceased is usually seen at about half past six. ”

The light in Xu Chengyan's eyes dimmed, and a trace of doubt continued to overflow in his heart.

"Therefore, this case should have been premeditated, not improvised. Qiu Lan pursed her lips, thinking about it in her head.

"Well, and according to the evidence at the scene, the deceased's change is still there, and there are headphones in the bag, but strangely, we can't find the deceased's mobile phone. Xu Chengyan lowered his eyes, his face heavy.

"According to the records of the telecommunications company, the last phone call made by the deceased was the night before the incident, but the network signal disappeared at about 4:35 this morning, and the place of disappearance was Dong Lang Shan. ”

"So the deceased must have brought a mobile phone, and the phone is missing, but it is suspicious. Qiu Lan frowned thoughtfully.

The contents of this mobile phone may be the cause of the death of the deceased.

"By the way, Officer Xu, when you open the report, when I conducted an autopsy, I found two very suspicious signs. Qiu Lan flipped through the materials, and finally stopped on the side where the two photos were printed.

These two photos were found when she was irradiated with ultraviolet light just now, and they are two sets of handprints, but the fingertip distance shown on these handprints is different.

Therefore, Qiu Lan once suspected that at the scene of the murder, the deceased should have been attacked by two people, otherwise, the drug and the heavy blow to the head could not be explained.

"Officer Xu, the first photo you see now is that I found the deceased's face, and it is a bruise caused by someone pinching the deceased's cheek with his hand. ”

After speaking, Qiu Lan pointed to a photo below and said in a cold voice: "And this one is the handprint I found in the deceased's left upper arm, and I speculate that someone used his right hand to control the deceased from behind." ”

"But the two mudras are not supposed to be made by the same person, and one of them should have a physical defect. Qiu Lan lowered her eyes, her eyes cold.

Listening to her words, Xu Chengyan looked at the two photos on the report carefully, and his expression gradually froze.

"The handprint on this one finger is only one finger on the left and three fingers on the right, while the five fingers on the photo below are complete. ”

"Yes. Qiu Lan nodded and spoke heavily, "And the distance between the hands on the face, that is, the length of the thumb and index finger fully extended, is twenty-two centimeters, while the left arm is twenty-five centimeters. ”

"Based on the relationship between the strength and the scar, it can be inferred that both are completely open marks, which can rule out the reason for the difference in hand spacing due to the size of the tiger's mouth opening. Qiu Lan stretched out a hand and simply demonstrated.

"Doctor Qiu, so you mean there were two murderers at the time of the crime?" Xu Chengyan silently lowered his eyes, his eyes dark and deep.

"I don't rule out the possibility of this. Qiu Lan nodded slightly, her lips pursed slightly.

After a while, she took the report, flipped the page to the next few pages, and then put it back in Xu Chengyan's hand, "Officer Xu, you should also pay attention to this photo." ”

The photograph shows the deceased's back with intermittent long strips of thin wounds, although these injuries are intermittent and discontinuous, but after proofreading with a ruler, it is found that they are all in a straight line.

In other words, the deceased's back was bruised in several long straight lines, but they were not continuous because of the different forces.

During the autopsy, Qiu Lan thought carefully about these scars, but she really couldn't think of what kind of thing could cause such special marks.

"I don't know what caused these stripes, but I can guess that they are regular stripes like fences and fences, but they are smaller and sharper, and they have different strengths. ”

"These marks are strange. Xu Chengyan stared at the imprint on the photo, his eyes were dark and sharp, and he was thinking carefully in his mind, "Moreover, there is another question that is incomprehensible." ”

"We found a kilometer between the bloodstained waters and the place where the informant found the body, but we searched all the avenues and trails, and found no traces of dragging, that is, we could not think of how the deceased moved. ”

"The corpse spots are divergent, that is, the deceased died in the water, and then was moved to the sand and raped, but why did you do this?" Qiu Lan couldn't help frowning, full of doubts.

"Well, this case is a bit tricky, we guessed that the deceased made a special appointment to meet someone in the park, so he was there at four o'clock. Xu Chengyan paused, pursed his lips, his eyes flowed, and his mind kept thinking.

"But now, the autopsy report shows that there are two murderers, so who is the other murderer?

Everything is still unknown, and the facts of the case are becoming more and more confusing.

Countless questions are still in the mind, waiting for them to crack and answer them.

"Okay, I'll try my best to investigate the case, Doctor Qiu, why don't we have a meal together, I see that you have just finished your work, and you must not have eaten yet." Xu Chengyan closed the report and gently hooked the corners of his lips, but his brows were still slightly wrinkled.

Hearing his words, Qiu Lan nodded, "That's what I said, the case has to be investigated, and I have to eat." ”

"Yes, by the way, Doctor Qiu, how is your body, is the cold getting better?" Xu Chengyan raised his eyes slightly, his eyes full of concern.

"Officer Lao Xu is concerned, I'm all right. Qiu Lan shrugged her shoulders and responded softly, with a little smile on the corner of her mouth.
