Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Chapter 426: Because of Mamapiao

There were a lot of old bloodstains in the wing of Song Tiejun's house. During the investigation, Lu Chuan found that some bloodstains were very old, three to five years, or even longer.

It can be determined that this wing is the scene of Song Tiejun's murder and dismemberment of the body.

Lu Chuan opened the iron stove that Song Tiejun was talking about. It was actually the coal stove that Song Tiejun usually used for blacksmithing.

The surface of the stove was very old, and it looked like an old thing at first glance. Sun Jianguo knew that this was something left by Song Tiejun's grandfather, and it was almost a hundred years old.

There was no coal burning in the furnace, but there was a lot of ashes.

Lu Chuan used the furnace hook to pull away the ashes, and knew that Song Tiejun was not lying. There were indeed ashes from burned bones in the furnace.

The main components of human bones include organic matter, minerals and water.

Among them, organic substances include proteins, enzymes, chondroitin, etc., which are important substances that promote bone growth and have active characteristics.

However, in terms of the proportion of bone components, organic matter accounts for a very small proportion, and minerals are the most important components of bones.

These minerals mainly contain calcium, phosphorus, sodium, magnesium, iron and other ions.

Among them, calcium ions are the most abundant and are the main minerals that ensure the hardness of bones. Calcium ions are also the largest ion among minerals in the human body, and their weight can reach about 2% of the human body.

The content second only to calcium ions is phosphorus ions, which can account for half of the total calcium ions.

Among the ashes of human bones, calcium ions and phosphorus ions account for 36% and 17% respectively.

Ideally, the ratio is about 2:1. If the ratio between the two is imbalanced, many problems will occur in the bones. If the ratio of calcium is large, the bones are prone to bone hyperplasia. If the ratio of phosphorus ions is large, calcium deficiency will occur.

The view in the side room was not good, and the furnace was pitch black. When Lu Chuan turned over the ashes, there was even a faint green light, commonly known as a will-o'-the-wisp. This is the process in which phosphorus ions react with the air.

"Take it away first."

Although this wing can definitely be the scene where Song Tiejun dismembered the corpse and burned the head, how did the case happen, why did it happen, what was Song Tiejun's motive for the murder, where was the first scene of the murder, and why was the time span so long? , cannot be determined just through on-site investigation.

The focus of the next work will mainly be on interrogation.

Wang Song was a pre-trial expert when he was in his own unit, and this time he also went into battle personally.

"Song Tiejun, tell me, how many people were killed in total?"

"How many can you name...just a few."

Song Tiejun's face was expressionless on the interrogation chair, and his eyes were lifeless, like a dead fish.

This is obviously very uncooperative.

"Didn't you fish out five corpses from Wangjiahe? I killed all five of them. Just sentence them to death and execute them immediately. Don't ask so many questions. I don't want to say anything. "

Next, Song Tiejun said nothing and remained silent.

"Song Tiejun, do you think you can escape legal punishment by remaining silent and saying nothing?"

"I have never thought about escaping any punishment. I killed the person and I admit it. You can just sentence me to death and that's it. Why are you asking?"

"what?"

"Well, come to the massage parlor, do you still remember the victim named Su Mo?"

"Of course I remember," Song Tiejun nodded: "I think he killed her at the end of last year, in November? I don't remember the specific day very clearly."

"Why did you kill her?"

"Why? Because she raised the price after the fact. She agreed on 280 yuan, but at the end she insisted on asking me for [-] yuan."

"They even called me 'Mamapi'!"

"If I don't kill her, I'll be sorry for myself!"

Song Tiejun's mood suddenly became a little excited, and he roughly talked about the killing process at that time.

"Then where did you kill her?"

"In the taxi, I strangled her to death."

"She just went out with you?" "I said we would stay the night, and she left with me."

Wang Song sighed.

Su Mo, when the crime team was investigating, they discovered that Su Mo had a mother who had cancer and a father who was hemiplegic.

The reason Su Mo went for massage back then was to earn money for her mother's surgery.

18, one life.

Just when Su Mo had almost prepared the money, he was killed by Song Tiejun.

"What about Chen Wang, the rice seller? Why did you kill him?"

"Why? I went to his house to buy 5 kilograms of rice, but that bastard gave me 4 kilograms of rice."

"I went to him to argue and asked him to give me the missing rice. He said that I would sneak out the rice when I got home to create trouble for him."

"After that, that bastard still called me mommy!"

"Damn it, I have to kill him!"

"Taxi driver, why did you kill him?"

"Take a job from me and call me mommy!"

In the monitoring room next door, Li Donglin and others were watching the interrogation.

"Specific language stimulation?"

Song Mingguang frowned and murmured softly.

When Song Tiejun answered why he killed Su Mo, the taxi driver and the rice seller Chen Wang, he mentioned one sentence. They had a conflict and the other party scolded him: "Mama Pi".

This is a Sichuan dialect, and it is an ugly curse word.

The conflict between Song Tiejun and these victims was actually not big. The difference between Song Tiejun and Su Mo was 20 yuan, and the rice seller was because he was short of two taels of rice. The taxi driver was because the other party cut in line and robbed him. live.

In fact, if you think about it carefully, these are all small conflicts in life.

It is impossible for Song Tiejun to only have similar small conflicts with these few people in his life. This kind of friction cannot be said to occur every day, but it is basically an uninterrupted process.

At present, Song Tiejun only killed these 5 people, and the three people mentioned now were all because they scolded him.

This reminds everyone of the life and work background of several people.

Either they are from Sichuan Province, or they have family members or parents from Sichuan Province who immigrated here.

In short, there is a high probability that these people can speak Sichuan dialect.

And Song Tiejun's wife's family... didn't come from Sichuan Province.

Others saw it, and Wang Song, who was interrogating, naturally discovered this as well.

"You... didn't kill them because you had conflicts with them... but because those people scolded you Mamapi?"

The emotional Song Tiejun suddenly calmed down.

After that, no matter what questions Wang Song had, he didn't speak.

"Wang Song, come out. Today's interrogation will end here first."

Li Donglin sent Wang Song instructions to end the interrogation.

"Let's all go to the conference room for a meeting."

The atmosphere in the conference room was much more relaxed than the last time.

Although many details of the case have not yet been completed, the murderer has been caught after all, and the rest is just a matter of time and effort.

The case is closed.
