The injuries on the deceased's body were many, very serious, and she clearly hadn't finished speaking.

Long Zihan and Liu Yuanheng were silent, looking at Chu Yiren, waiting for her to continue.

"The deceased had several parallel skin contusions on the outside of the middle of his right upper arm, and there was a 15 by 6.5 cm transverse incision wound on the lower lateral side of the right shoulder joint. ”

With the help of Wang Xiaoguang, the Chu Yi people turned the deceased over and examined his back.

"There are 9 intermittent staggered wounds of different depths on the right waist in the form of 'triangular' skin fissures, with a spacing of 1.2 cm, deep into the subcutaneous tissue, and the wound margin is neat. ”

Mo Bei, who was collecting physical evidence on the side, frowned and said, "Doctor Chu, these injuries of the deceased seem to have been caused by a variety of tools. But there was no murder weapon at the scene!"

Chu Yiren shook his head and said in a confused voice: "No, not necessarily ......"

"Long Zihan!"

Listening to Erin's shout, Long Zihan looked for it.

"Look!"

Looking in the direction pointed by Erin, Long Zihan saw that there was a bloodstain on the door frame of the back door of the deceased's house.

When I got closer, I looked closer, and it seemed that there were fingerprints on it. On the ground, there were some vague but still visible footprints walking outward.

"The murderer escaped from the back door of the deceased's house with a murder weapon after the murderer......"

Police station, conference room.

Wang Xiaoguang handed the autopsy report to Long Zihan, and then reported the autopsy results as simply as possible.

"The incision wound under the right shoulder blade of the deceased's chest and back corresponds to the injury, and the 8th to 11th thoracic ribs are transversely oblique fractures, and their sections are accompanied by fine bone fragments. The injury to the right shoulder joint was as deep as the bone marrow cavity of the humerus, and there was a 2.5 by 0.6 cm transverse wound on the humerus corresponding to the injury, which was in the shape of a 'sawmill', and the wound wall was rough with fine bone fragments. Flap wound at olecranon on right elbow ......"

Long Zihan frowned and asked while looking at the autopsy report, "So what?"

Wang Xiaoguang choked, knowing that he didn't have the patience to listen, and said the result directly.

"Judging from the wounds, the injuries on the deceased's body were all caused by a carpenter's handsaw. ”

Mo Bei said in surprise: "But the injuries on the deceased's body don't look like they were caused by a tool. ”

Chu Yiren explained: "In fact, there are many characteristics in this case that confirm that the murder weapon was a carpenter's handsaw. ”

"Tell me about it. ”

"First, the damage caused by waving a carpenter's handsaw into the plump and flat part of the human body is in the shape of a 'wave'. Second, the serrations will form a triangular single-tooth fissure on the soft tissue of human skin, which is wide at the top and narrow at the bottom, different shades, evenly spaced, and intermittently staggered. ”

As she spoke, she coughed a few times.

Wang Xiaoguang handed her a glass of water and motioned for her to drink water and rest.

Then, taking her words, he said: "Third, the bone damage caused by the sawtooth cutting the human body, the typical saw groove is formed when the backbone is not broken, which is characterized by the same width and narrowness, the roughness of the saw groove wall, and the saw groove is attached to bone fragments and bone fragments. ”

All of what they said was reflected in the dead.

Wang Xiaoguang continued: "In addition to the flap wound caused by waving a handsaw at a certain angle to the protruding part of the olecranon of the right elbow, the skin abrasions caused by transverse action on the right upper arm are arranged in parallel......

After Wang Xiaoguang finished speaking, Chu Yiren said: "If there is no murder weapon left at the scene, it is indeed easy to mistake it for a variety of tools. ”

Wang Xiaoguang nodded and said, "We found the dandruff tissue from the nail gaps of the index finger, middle finger, and ring finger of the deceased's right hand. ”

Long Zihan asked, "What about the physical evidence?"

"Although there was no murder weapon left at the scene, in addition to the blood of the suspect, there were rich fingerprints and footprints in the traces of the fight. In addition, the bloodstains on the back door confirmed that they were the deceased, and the fingerprints and footprints on the ground were left by the murderer. ”

Liu Yuanheng sighed and said helplessly: "No one has seen the deceased's family in the past to ask for money, it is useless to have these evidences, I am afraid that we will have to go to the casino frequented by Wang Zhiheng first to find clues." ”

The two doors in front and back of Wang Zhiheng's house can be said to be accessible in all directions, and it was lunch time at the time of the incident, and almost every household was cooking and eating, and no one paid attention to who went to his house.

Moreover, his house is at the head, and the neighbors on the side are one household, and the front and back are far away.

Even if they hear the sound of scolding here, the neighbors are already a little scared, and out of the mentality of "more things are better than less", they will act as if they don't know anything.

Mo Bei said: "Wang Zhiheng is a very scoundrel and has never borrowed money and never repaid it. Over the years, because of gambling, his wife was separated, and he borrowed all the people who could borrow money. Even some of his neighbors, he still owes a sum. Almost no one cares about him now. ”

Erin sighed lightly: "Gamblers always want to turn over their books, change their fate, and go to the pinnacle of life from now on." But they don't know that nine times out of ten, they lose. ”

According to neighbors, Wang Zhiheng has been the same as usual recently, except that the casino is his home, and there is no special situation. ”

After Mo Bei finished speaking, he asked Long Zihan: "Are we going to the casino now?"

Everyone looked at Long Zihan and waited for him to give the order.

Long Zihan said: "Of course I want to go, the other party once said, 'pay back', then the destination of this money is likely to be the casino." Don't sit still, get to work!"

Erin pursed her lips and asked, "Are you okay?"

Long Zihan's expression flashed with grief, and then he sighed and said: "My mother's case has no clues, no evidence, and I can't do anything for the time being, so it's better to find something to do at this time, keep myself busy, and it won't be so annoying." ”

In fact, everyone understands that where he is "annoying", he is clearly sad.

His mother was killed, and he knew who the murderer was, but there was no evidence, and he couldn't do anything. Whoever rests on this matter will not have a good time.

Erin nodded and said, "Okay, it's okay to be busy." ”

When the group went to the casino that Wang Zhiheng frequented from the neighbors, they finally found the casino's lender.

"Hello Long Shao!" The lender saw Long Zihan and hurriedly greeted him.

Long Zihan asked, "Mr. knows Wang Zhiheng, right?"

"Wang Zhiheng?" The lender looked at the little brother beside him, and after the little brother read two sentences in his ear, the lender immediately had a clear expression.

He said, "Oh, I see, Officer Long is talking about Wang Datou! I know, I know, he still owes us two hundred and still hasn't paid it back." ”

Long Zihan asked, "I don't know, have you gone to collect debts recently?"

The lender said, "He came yesterday and promised me that he would come and send me money today, what's the matter?
