Wang Si actually did not bring any experts to solve cases this time. After all, inspections are not about handling special cases, so Bai Song and his team can be considered the professionals in the inspection team.

In such a unit, you must never underestimate a leader. They may not be strong in some areas, but they are definitely not simple. Although Bai Song is not highly regarded in the Criminal Investigation Bureau, everyone knows what it means to be seconded by the whole organization.

Therefore, Wang Si agreed to include Bai Song and others in his inspection team after careful consideration.

…

If this case hadn't happened suddenly on New Year's Eve, Wang Si would not have cared about it. But since it is a big deal and might attract attention, he has to take care of it, and he has to do it well.

It was not possible to just go there directly, as Director Li didn't understand some things. In the end, Sun Jie and Wang Huadong went to the technical team of the Criminal Investigation Detachment of the Municipal Bureau to get some things before rushing to the scene.

Although people who have gone there before may have already brought their own, Sun Jie thinks it is better to prepare it yourself.

The conditions here are not as good as those in Tianhua. When Sun Jie was in Jiuhe Branch, he had encountered the situation of insufficient autopsy materials many times. On-site trace detection and body detection require a lot of reagents and tools, and not every branch can guarantee the supply, because the times are changing, and the reagents are also changing.

There were many missing items in the Municipal Bureau, so Sun Jie could only quickly select some of them, and then everyone went straight to the scene.

After arriving at the scene, Bai Song and others were treated very well, and most of the people inside came out to make way for Bai Song and others. But Bai Song and Liu Shuyuan did not go in, and only let Sun Jie and Hua Dong in, and brought a few local forensic doctors from Linyang.

According to current intelligence, the deceased are a family of three, a middle-aged man, a middle-aged woman, and an 11-year-old boy. There were signs of a struggle at the scene, and the cause of death was a sharp weapon, that is, a knife, piercing the vital parts, causing excessive bleeding.

This kind of scene is often very bloody, with the entire room covered in red, and there is no place to step. It looks like hell on earth.

The neighbor arrived and opened the door, and then he was so scared that he forgot to close it. The room was already cold, and it quickly lost temperature and dropped below zero.

The forensic doctor determined that the time of death was about 6 hours, but the exact time has not yet been reported.

Inside the house.

"Atropine was dripped into the conjunctival sac, and there was a mydriasis reaction. The time of death should be within four hours." Sun Jie said: "The temperature dropped after the door was opened, causing the body temperature to drop faster than originally estimated. Judging from the formation of rigor mortis, most of the rigor mortis appeared, and the livor mortis was distributed in patches. There should be no objection to the time of death of 3 to 4 hours. The middle-aged man lost too much blood, which affected the judgment, but the time of death of the three people deduced at the scene should not differ by more than five minutes, because the blood had not yet coagulated when the person who died later stepped on it."

"Leader, if you say so, it must be according to your calculations," the local medical examiner nodded repeatedly, "The bodies all had a large amount of blood loss, and the phenomenon of 'overbirth' is not as obvious as normal death, so our calculation is slightly longer."

"Well, there's actually not much difference. The question is about the cause of death. The traces left at the scene indicate that all three died of excessive bleeding, but only the boy showed obvious counterattack. Have you found any evidence of a fourth person at the scene?" Sun Jie asked. After all, he arrived relatively late.

"There are a lot of footprints," said an old forensic doctor. "We collected the footprints of the neighbor before we came. After we eliminated them, we still found footprints of no less than ten people in the yard. It was very messy. Not only that, we also found some hair, clothing and other samples other than those of the three people in the house."

"Please show it to me." Wang Huadong came over and said politely.

…

The surveyors in the house were working in full swing, and Bai Song and others were also not idle, checking every household in the entire village.

Speaking of which, Bai Song has never dealt with any homicide cases in the rural areas. There are some such cases in rural areas in Tianhua City, but they are completely different from those here.

The rural areas here are mainly farming areas, and most of the young people in the village have gone to the city. In terms of driving distance, this village is less than an hour away from Linyang City.

Linyang City is also facing many problems now. The only city in the entire Qin Province that can be considered prosperous is Chang'an City, and a large number of young people are pouring into Chang'an City.

In this village, there are usually many lonely elderly people, and the children are working outside. Even the family of three who died were working outside the city, and they returned home for the New Year.

Both the parents of the middle-aged man and the middle-aged woman are gone, and the last one to pass away was the middle-aged man's mother. The old lady was paralyzed in bed, and the woman had been taking care of her at home, which was very difficult. Later, the old lady passed away, and the villagers said that the family's future life would be better, but this situation happened.

Judging from the scene, there were very few valuables in the house, even abnormally few.

According to the villagers, the man worked outside and his family was not well off. It was impossible for him to have only a hundred yuan at home when he returned home for the New Year!

This family didn't have WeChat, Alipay or anything like that, and after searching the house for quite some time, the total amount of cash was less than a hundred yuan.

As for the scattered footprints in the house, this is easy to understand. It is almost the New Year, and there will always be people visiting when they come back from work. Today is New Year's Eve, so it is normal to have people visiting.

"Is this the first scene?" Bai Song asked Wang Huadong.

"Definitely. With this kind of blood spurting out, it's impossible for the person to be killed outside and then brought in," Wang Huadong said. "Several of the wounds are arterial injuries, and the blood loss rate is very fast."

"Why is there so little New Year atmosphere in this house?" Bai Song discovered a question that few people paid attention to: "Even if someone killed for money, why is there no New Year atmosphere in this house?"

"Leader, according to our local custom, for families like theirs where parents passed away this year, we won't celebrate the New Year in a grand manner," said a local policeman. "Besides, since they have a funeral, it's not convenient for them to go around paying New Year's greetings this year. It's normal for others to come over to pay New Year's greetings."

"Oh," Bai Song nodded, and then asked Huadong: "Tell me about the situation at the scene, from beginning to end."

"Okay." Huadong began to tell the story.

The evidence at the scene was very rich. The property in the house had been searched, and it was not rushed at all. The murder weapon was a kitchen knife, which was left at home. Fingerprints were collected on it, and they matched the fingerprints of the middle-aged man.

Judging from the scene, it is possible that the middle-aged man directly hacked his wife to death, then hacked his son to death, and then committed suicide - the middle-aged man's wounds showed suicide-style knife marks.
