In the case file of Boss Song's death, there is some information that has attracted Wu Cuo's attention. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

According to the records of the investigation report, Song Xiaoer has a bad record in his hometown, relying on himself to go to a martial arts school, some fists and feet, mixing with ruffians all day long, and becoming a ruffian leader.

Most of these ruffians are minors, they will block the school gate, rob the students' pocket money, steal things in Internet cafes, and sometimes do things to help people fight and do ordinary things, therefore, Song Lao Er is not very old, but he has entered the police station three times and left a criminal record.

Boss Song disciplined his younger brother many times, and the brothers even fought a few times because of this.

Song Xiaoer is not his brother's opponent, he is beaten every time his nose is blue and his face is swollen, but he has fallen into it, he likes the feeling of being sought after by his younger brother, he likes to make money in his own way, he no longer wants to live the kind of life when he has to be careful with his brother for a few dollars.

Besides, if you are taught a lesson by your brother and wash your hands and change your ways, won't it become a coward? What will his thugs think of him?

Because of Song Xiaoer's repeated teachings, the brothers have a long-standing grudge, and even turned against each other for a time. Song Xiaoer once threatened to teach his brother a lesson and get back the lost face, but his attendant has confirmed that Song Xiaoer is just talking, and has not put it into action, in fact, in private, he is still good to his brother, if he has money, or if he has any good things, he will leave a share for his brother.

After all, the two children have been dependent on each other since childhood, and this relationship cannot be wiped out by a fight.

Later, Song Xiaoer offended another local gangster named Du Youzhi, and the other party released a word to cut Song Xiaoer with a thousand knives.

Not long after, Boss Song died, and his death was tragic.

Of course, Song Xiaoer thought that the murderer was Du Youzhi, he gathered everyone under his command at the first time, and beat several of Du Youzhi's subordinates half to death, but fortunately, the police arrived in time, which brought the situation under control.

It's a pity that Du Youzhi knew that he had been murdered and had fled, and his whereabouts are still unknown.

Song Xiaoer was criminally detained for 3 months because of a crowd fight, but fortunately, the other party was only injured, not dead or disabled, and the other party was also bad, so Song Xiaoer was not sentenced to a heavy sentence.

After coming out, Song Xiaoer seemed to be a different person, dropped out of school, no longer interacted with those gangster friends in the past, and came to Jingbei City to work alone.

The above series of descriptions made Wu Cuo a little in a trance, he didn't expect that the Song Xiaoer he saw yesterday - the security guard who seemed to be honest - used to be a local snake.

Wu Cuo opened the autopsy report on Boss Song again.

Life: Boss Song

Gender: Male

Age: 19 years old

Height: Approximately 178cm

Physical characteristics: Sturdy build, dark complexion

Hair: Black inch

Cause of death: Death from hemorrhagic shock due to rupture of the femoral artery.

There were as many as 107 wounds on the surface of the body, which were messy and of varying depths, including one wound that penetrated deep into the femoral artery.

Judging by the shape of the wounds, the scars were left by the same knife.

It is important to note that some of the scars do not have a life reaction, and such scars are left after death.

Even the corpse refuses to let go, how much revenge does it have?

In order to prevent anyone from identifying the deceased, the murderer deliberately destroyed the deceased's fingerprints, face, and cut off the deceased's left forearm.

According to Song Xiaoer's recollection, during the summer vacation three years ago, Yang Guangzhu went back to the village to visit the Song brothers, and took the two of them into the city to buy clothes.

Song Xiaoer was protected by Boss Song and was safe and sound.

That. Boss Song suffered a fracture of his left forearm, a steel nail, and a slight concussion, and Yang Guangzhu also had a slight concussion.

The steel nail on the left forearm bone of Boss Song is also the basis for identifying the deceased, so the murderer cut off his left forearm and disposed of it, making it impossible for the police to find him.

However, because the body was wearing Boss Song's clothes, coupled with Song Xiaoer's identification, it was finally confirmed that the deceased was Boss Song.

What follows is a description of the suspect Du Youzhi.

Du Youzhi, nicknamed Du Dali, after dropping out of junior high school, he mixed in street Internet cafes and game machine halls, and then gathered a group of dropout children to form gangs. I helped people see Internet cafes and open billiard halls, but the billiard hall was not well managed and eventually closed down.

He was 21 years old when he absconded, 180cm tall, sturdy, dark-skinned, with an inch head, and a ring-shaped tattoo on his left ring finger, which he tattooed with his ex-girlfriend.

Wu Cuo looked at the photo of the suspect Du Youzhi and fell into deep thought, there were a few questions he couldn't understand.

First, since Song Xiaoer and Du Youzhi have a personal vendetta, why didn't he attack Song Xiaoer, but found Boss Song? Could it be that you have recognized the wrong person? That's!

Second, only a murderer who is almost insane will not spare the corpse after death, and constantly cut the corpse, which is often a murder out of passion, rather than a long-standing premeditated murder, which is not in line with the situation.

Moreover, the act of covering up the characteristics of the corpse shows that the murderer is relatively calm in his heart, and there is a huge contrast with the almost insane murder process, and there are also doubts.

Third, Boss Song's arm was injured three years ago, at that time Song Xiaoer and Du Youzhi had not yet formed a feud, and the two sides had no intersection, how could Du Youzhi know that Boss Song had steel nails in his arm?

Fourth, there was a highly recognizable scar on Du Youzhi's left ring finger, and the corpse, which could only be identified by virtue of his clothes and Song Xiaoer's experience, had his entire left forearm gone.

These doubts were taken together, which made Wu Cuo have a strange idea: Is the deceased really Boss Song? Is the murderer really Du Youzhi?

However, Du Youzhi did absconded in fear of crime.

Wu Cuo gathered his mind, looked at the case file of the hamstring case again, and listed the clues known so far one by one:

First, the murderer is skilled, dressed strangely, and hurts people at night every time;

Second, in the fifth case, witnesses found that the murderer had a scar on the left side of his eyebrows, and Yang Guangzhu happened to have a scar at the same location;

Third, in the fifth case, witnesses found that the murder weapon was a glass ballast, and there were three fingerprints on the glass ballast stained with the victim's blood found not far from the scene, but the owner of the fingerprints has not yet been found.

Fourth, five victims had more or less had a relationship with Yang Guangzhu;

Fifth, Yang Guangzhu and Song Xiaoer can do some kung fu, but according to the investigation, when the five murders occurred, both of them had an alibi that could not be overturned.

Wu Cuo knew that he didn't have Yan Ruyu's ability to remember things, so he could only use notes.

Near dawn, when Wu Cuodang sorted out all the doubts in his notebook, he finally grabbed a rope in the messy thread.

Scar! The scar on the left side of the murderer's eyebrow is the key to the hamstring case!
