"The wound on the back of the head of the injured Qi Mo was caused by a heavy blow, and it is speculated that the fire bricks found at the scene of the murder weapon were found. Qiu Lan stood beside the bed with a ruler, carefully comparing the wound and not smiling.

"The wound was somewhat concave, about two centimeters long, and it is assumed that the bleeding was not large at that time. Her eyes sank, thinking about something in her heart, and a trace of doubt flashed in her eyes.

Xiao Cong, who was standing on the side, noticed her strange appearance and slowly spoke: "Doctor Qiu, have you found anything?"

"Hmm. Qiu Lan nodded, her expression solemn, "The strength of the murderer's blow on the head of the injured person is completely different from the blow to the deceased. ”

This point made her very puzzled, although the murder weapons used in the two murders were different, the strength of an adult's blow would not be so far apart.

The wound on the deceased's head directly caused intracranial hemorrhage, and the injured person should not have injured the inside of the brain, it can only be regarded as a skin injury, and at most it is necessary to check whether there is a concussion, which is not fatal.

"Qi Mo, I've finished checking the wound on your head, I'm going to check if there are any injuries on your body now. Qiu Lan slowed her eyes and stared at her gently, her voice soft.

"Good. Qi Mo nodded, and then took off his hospital gown.

After a closer examination, Qiu Lan found that there were no other superficial injuries on her body, except for two bloody marks on her left shoulder, which seemed to be caused by scratches.

"Satoshi, prepare the UV light. She pursed her lips and commanded softly.

"Okay, Dr. Cho. Satoshi opened another alley, took out two pairs of glasses and a lamp, and handed the lamp and one of the glasses to Qiu Lan.

After putting on her goggles, she took out the ultraviolet light, "Qi Mo, close your eyes, I want to check the tissue under your skin." ”

As soon as the light line swept into the left shoulder of the injured person, Qiu Lan saw a handprint, "Xiao Cong, a bruise was found on the left shoulder, take a ruler, and prepare to take a picture."

"It was supposed to be a scratch, and I suspect that the killer tried to catch the victim from behind, but his hand slipped, so it caused blood and subcutaneous bruises. ”

Seeing this trace, Qiu Lan's eyes sank slightly, and her heart was full of doubts.

After conducting oral and blood forensics, she and Xiao Cong put away the instruments and walked out with heavy faces, while Xu Chengyan was waiting outside.

"How's it going?" ”

"Officer Xu, I have found out. Qiu Lan pursed her lips, frowned slightly, and the expression on her face was a little cold, "I was examining the wound on the wound on the wound's head just now and found that the force of the wound was two to three times smaller than the wound on the deceased's head. ”

"That kind of force is not enough to kill at all. ”

Hearing her words, Xu Chengyan's eyes gradually dimmed, and a few small wrinkles at the corners of his eyes were full of doubts, "In other words, the person who injured Qi Mo and killed the deceased Tan Peiling are not the same person." ”

"Yes, but there's another possibility. Qiu Lan lowered her eyes and told him what she had guessed just now, "That is, the murderer who injured the person and the murderer who killed the person are the same, but the murderer has no intention of killing the injured person at all." ”

"Doctor Qiu, I see what you mean. Xu Chengyan nodded slightly, the expression on his face became clearer and clearer, "I will focus on investigating the people who are related to Qi Mo and live in Donglang Mountain." ”

"She said her grandmother lives here, and I'll send someone to investigate the people around who have a good relationship with her grandmother. ”

"Hmm. Qiu Lan nodded silently and continued to speak: "Also, I found a handprint on her shoulder, and this handprint is probably caused by the murderer. ”

After speaking, she looked at the assistant Xiao Cong on the side and said softly: "Xiao Cong, you turn around and help me make a demonstration for Officer Xu." ”

"Good. Satoshi pursed his lips and nodded, then turned his back to them.

Qiu Lan put down the alley in her hand, tiptoed, stretched out her hands to climb Xiao Cong's shoulders, and then pulled back.

"Officer Xu, that's it, the murderer should have wanted to hold the injured person, but because the clothes the injured person was wearing this morning were made of nylon fabric, he couldn't catch it, and his hand slipped and caused such marks. Qiu Lan pursed her lips, and her voice was a little colder.

"And this mark is very special, according to the normal situation, when pulling a person, I will use the other four fingers of the five fingers in addition to the thumb, but in Qi Mo's left shoulder, I only found three fingers. ”

Three fingers?

As soon as he heard this, Xu Chengyan instantly thought of a suspicious point on the deceased's autopsy report.

"Doctor Qiu, do you mean that the person who caused the wound on the injured person's shoulder and the person who caused the deceased's facial bruise are the same person, both of whom are suspected to have no little fingers?"

"Hmm. Qiu Lan nodded solemnly, her eyebrows moved slightly, "There are indeed only three fingers on the shoulder, the index finger, the middle finger, and the ring finger, so I think these two places can be connected." ”

"Okay, Doctor Qiu, I understand the situation, so please go back to the police station and make a detailed report and send it to me. Xu Chengyan glanced at her softly and gently hooked the corners of his lips.

"Don't worry, I'll sort it out as soon as possible. Qiu Lan lowered her eyes and said softly: "By the way, Officer Xu, I will leave the matter of Qi Mo to you, I will go back to the police station to sort out the information first." ”

"Good. ”

After leaving the hospital, Qiu Lan and Xiao Cong returned to the coroner's room of the police station together, sorted out the information of the rape and murder case in Donglang Mountain in detail, and then made a report and sent it to colleagues in the serious crime team.

At six o'clock in the evening, in the underground parking lot, Qiu Lan sat in her car, closed her eyes, and gently pressed the corners of her eyes to soothe her nerves.

This case is a bit tricky to start with.

Two murderers, one deceased, one wounded, three crime scenes, and no traces of towing can be found on the path between the two crime scenes related to the deceased.

And the strange scar on the deceased's back, what was it that caused it?

They can be connected to each other in a straight line, but the force is uneven, causing intermittent and discontinuous scars?

Many questions swirled in Qiu Lan's mind, making her a little worried.

At this moment, the mobile phone in the handbag rang with the classic English song "Coming Home".

The melodious and tactful singing voice quietly came into Qiu Lan's ears, she opened her handbag, took out her mobile phone, and a string of unfamiliar numbers on the mobile phone screen fell into her eyes.

This phone number is based on the city.

After hesitating for a moment, she still answered the phone, "Hey, hello." ”

"Hello, Lan'er. A low, shrill voice came from the other end of the line.

Originally, Qiu Lan only felt familiar when she heard this voice, but she didn't know who it was, but this title, except for Xue Yancheng, no one would call her "Lan'er".

"Xue Yancheng, you really don't hit the south wall and don't look back, last time you followed me to find my house, and now you find my phone number, what's the matter? Do you know that I work in the police station, so you want to come in and sit for a few days under the pretext of harassment?"

Qiu Lan bit the back groove fiercely
