"I found it, Liang Dafu's murder weapon is a cable."

Uncle Da handed the freshly printed test report to Shi Chong.

Reports show that there are multiple people with residual dander and blood on the cables used to secure lifebuoys on the side of the fishing boat.

"Unfortunately, due to the harsh climatic conditions at sea, most of the DNA was decomposed, and only the DNA of Li Li and Liang Dafu was extracted." Uncle Da said regretfully.

Li Li was the last victim to die at the hands of Liang Dafu, and thanks to the evidence provided by her body and whereabouts, the chain of evidence in this case was finally completed.

"The DNA test results for three fingernails came out, and we extracted a partially mutilated DNA fragment from one of the nails."

"After comparison, we found that these mutilated DNA fragments were at least 30 percent similar to Liang Dafu's DNA."

Zhu Jiangjiang walked into the office and said.

These DNA fragments came from women, which means that the owner of one of the nails is Liang Dafu's mother.

Liang Dafu's father died in an accident when he was 12 years old due to alcoholism and fell into the sea, after which Liang Dafu's mother threw Liang Dafu to his mother-in-law in the countryside to raise, and remarried until he died of esophageal cancer 11 years ago.

"Mrs. Liang had reported that Leung Dafu's domestic violence had started 11 years ago, and I suspect that his mother's death may have been the trigger."

Queen Bee curled her long hair with one hand and drank the soy milk on the table.

Liang Dafu's case spans a long period of time, has many victims, and is complicated.

In order to save time and close the case as soon as possible, everyone eats breakfast in the car or in the office.

"I thought so too, so I asked Lan Bo to use eleven years ago to seven years ago as a node to investigate Liang Dafu's social circle and Jinghai's criminal case about young women."

Zhu Jiangjiang posted the information he had investigated on the bulletin board.

The reason why it ended seven years ago is because according to Mrs. Liang's confession, the coconut snail was thrown away when she moved seven years ago, so the time of the accident of the three victims must have been within four years.

"Zhao Ying, a student at Jinghai University, was killed by J in an alley near a bar on the way home after dinner, and the cause of death was mechanical asphyxiation, and the distal end of the left ring finger was cut off and taken away by the murderer."

Zhu Jiangjiang pointed to one of the photos and said.

"I compared Liang Dafu's fingerprints with the only fingerprint left on Zhao Ying's skin by the murderer, and the results showed a match."

Another victim was Yu Yan, a professional convenience store employee who was killed on her way from work.

This time, Liang Dafu was obviously more cautious, did not leave any evidence on Yu Yan's body, nor did he directly cut off the distal end of his ring finger, but chose to directly pull out the nail of his ring finger with iron tongs afterwards.

The two cases were two years apart, and the tools and modus operandi were different, so they did not arouse the association of the Jinghai police at that time.

"Nine years ago, Liang Dafu used to sell breakfast near Jinghai University, and I think that's why he has his eye on Zhao Ying."

Zhu Jiangjiang has done a comprehensive investigation into these two murder cases, and the deceased is gone, and finding out the truth about these unsolved cases is the best explanation for the family.

"I see! No wonder I always think this person is familiar! ”

It was Qiu Zhiwen, the captain of the first criminal investigation team, who suddenly spoke, and his thick big hands were clenched into fists and smashed on the desk, his face full of self-blame.

Seven years ago, he was an ordinary police officer who had just joined the first criminal investigation team, and he once followed his colleagues to the building near the scene of Yu Yan's incident to inquire about the situation.

And Liang Dafu is the security guard on duty in that building!

"I remember when we asked him where he was from 12 o'clock to 1 o'clock and if he noticed any movement, and he said that his wife came to bring him supper that night......

Presumably, Mrs. Liang didn't see Liang Dafu when she went to deliver supper, and she only thought that he went to PC.

PC is inherently illegal, so it is natural to cover for her husband.

"Captain, the lab has sent a new test report. The fermenting agent and emulsifying degreaser used by Liang Dafu in the treatment of nails were compared with the ingredients used in the tanning of human skin in the hunter case. ”

Zhu Jiangjiang was slightly surprised, and she looked at Shi Chong, who had just hung up the phone.

The comparison test report is just her subconscious idea, since Liang Dafu cherishes Wang Sixi, he is also likely to make friends with common hobbies in the chat room.

As a result, as expected!

"It's time to go back." Shi Chong said in a deep voice.

Just now, it was Lan Bo's call, and the Blue Mountain City police found a skinned female corpse in the Manjushri Bodhisattva Hall of Tiantai Temple!

……

"Boom!"

The man threw the stiff body in the compartment on the inside of the carriage and pulled a white plastic sheet over it.

The interior of the carriage is mainly white, and when the frost condenses, this white plastic sheet will become more inconspicuous.

The man let out a hot breath, endured the pain and pushed aside the hanging white-striped pig and jumped out of the carriage, and when he raised his eyes, he saw the little girl standing at the back of the car.

The little girl looked like she was about six or seven years old, her hair was cut very short, and her short sleeves and long pants were loose and did not look very fit.

"Why did you run out and have a nightmare?"

As soon as the man's voice fell, he looked at the little girl's blank face and remembered that his daughter couldn't hear it.

He touched the little girl's head, gestured to the cab, and motioned for her to go back on her own.

Fortunately, the little girl was very obedient, and she climbed into the back seat of the cockpit on her hands and feet, and lay down on the cot in the lounge.

"Don't come out, sleep well."

The man glared and gestured to be beaten, and pulled up the curtain in the middle of the front and back rows.

The silver moon is falling in the east, the sky is about to brighten, and we have to speed up.

There are not many vehicles driving on the highway, so there is no trouble with traffic jams.

In order to avoid the checkpoint ahead, the man drove down the ramp in advance, relying on his familiarity with the terrain to find a country road with potholes.

This path is a shortcut from the Blue Mountains to Yunhe City, and there were originally several stone piers that restricted traffic, but unfortunately it had already been moved away by passing drivers.

"Damn, it would be nice to be able to throw it in Qinglong City. These doglegs smell a little smell and urinate everywhere, what's the use of crowd tactics, I really think I can catch people without using my brain. ”

Soon, the destination arrived.

The man skillfully turned off the lights, glanced at the quiet lounge, threw away the cigarette butt in his mouth and moved out of the car step by step.

On both sides of the road are patches of tea plantations, the frosted branches are green, and the scale is almost meaningless compared to the 10,000 acres of tea fields at the junction of Blue Mountain and Qinglong.

The man walked along the ridge with the steaming corpse on his back, and his increasingly weak body made it more and more difficult for him to move, and he began to gasp for breath before he had gone far.

Before he could reach the expected position, a dog barked in the distance.

"Damn!"

Afraid of being discovered, the man spat on the body, threw the body into the field, turned around and hurried away.

Both chapters have been changed, so don't worry! Love you guys!
