Last night, the couple discussed taking the earliest high-speed train this morning to see their daughter, and planned to celebrate her birthday in advance, otherwise they would have no time to get busy.

The reason I chose today is because they called their daughter a few days ago and accidentally learned that their daughter is on vacation today.

The moment they entered the room, they saw blood on the floor. Walking along the blood, they saw a terrifying scene - a large amount of blood was leaching from their daughter's abdomen, and she lay motionless on the floor, and a knife was still stuck in her abdomen.

When Zhao Hao and others arrived at the crime scene, the surroundings were already protected by police from the police station in the jurisdiction, and Wu Yuan, the captain of the Criminal Investigation Detachment, was also standing among the crowd.

Seeing Zhao Hao coming, Wu Yuan took the initiative to meet him.

Zhao Hao and Wu Yuan had known each other in the Criminal Investigation Corps before. At that time, Wu Yuan liked to call Big Brother Zhao Hao, but in fact he was not a few years younger than Zhao Hao.

Later, Zhao Hao chose to retire after experiencing the arson case until he was invited by the director of the Municipal Public Security Bureau to form a serious crime team, and serve as the leader of the serious crime team. Wu Yuan also changed from an ordinary criminal policeman in the Criminal Investigation Corps to the captain of the Criminal Investigation Detachment of the Xiangnan District Branch of Zhijiang City.

"Brother Zhao." Wu Yuan walked forward, habitually took out a cigarette and handed it to Zhao Hao.

Zhao Hao waved his hand and refused.

"What's going on?" Zhao Hao bypassed Wu Yuan and walked straight upstairs.

"According to the preliminary investigation, the deceased is named Gu Ningxue, a female, 25 years old, and is an employee of a cinema in Shunfu Commercial Street in Qiang. She lives alone in this house on weekdays. Her parents are from Fengjin County and basically don't come to Zhijiang City. Today, she mainly wants to celebrate her birthday with the deceased and have a meal together. Unexpectedly, she opened the door and saw her daughter lying in a pool of blood."

Zhao Hao is still very satisfied with Wu Yuan's investigation efficiency. It is good to be able to investigate this information from less than an hour and a half since the discovery of the deceased.

Zhao Hao walked along the safety passage to the second floor and saw two policemen standing in front of a dark red iron anti-theft door.

One of the police officers walked up and said, "The mother of the deceased just now fell into a coma due to sadness and is now being sent to the hospital. The father of the deceased was accompanied to the hospital."

After saying that, the two policemen left this floor. Now it is the investigation process of the serious crime team. Standing here may affect the case handling.

Zhao Hao made way for Huang Ke. Huang Ke took out two kinds of powder and ultraviolet lamps from his criminal survey box.

Usually, the skin of our hands has many sweat pores that are invisible to the naked eye. These tiny sweat pores will constantly secrete sweat. Therefore, when people come into contact with something, they will theoretically leave fingerprints on it, and objects that adhere to fingerprints are academically called objects.

There are many types of objects. In theory, as long as it is solid, fingerprints can be left, and there are also many fixed types.

For example, if you leave a fingerprint on a white paper and you use white powder to treat it, it will definitely be invisible because the two are the same color. However, if you use black powder to treat it, the effect will be very obvious.

The door handle is a place where fingerprints are easily left. When you insert the key, you will habitually hold the door handle and pull it inward so that the key can be inserted more easily and not easily stuck. When you hold the door, your fingerprint has been printed.

The surface of the door is a smooth paint surface. Although there are many things that deal with fingerprints, such as powder, solutions, and some chemicals, the fingerprints collected from powder are the best for this non-permeable object.

Huang Ke intends to collect fingerprints on the door handle and the storefront. If the murderer is a person with a key, he may leave fingerprints on the door handle. If he is an outsider, he may also leave fingerprints on the storefront when he knocks on the door or listens to the movements close to the storefront.

The front of this anti-theft door is dark red, so the yellow is treated with silver-white silver powder. The door handle is made of metal, so gold powder can play a good role.

"Brother Liao, take a photo."

Liao Zhiguo, who had been waiting, picked up the camera and took a photo. A few minutes later, Liao Zhiguo signaled that the photo was finished. Huang Ke lifted up the footprint survey lamp and walked in, while the rest were waiting outside.

This is the basic process for the serious crime team to solve the murder case that enters the house. Huang Ke is responsible for extracting fingerprints and footprints, Liao Zhiguo is responsible for taking photos, and Zhou Jiaxin is responsible for conducting the initial examination of the body, Zhao Hao analyzes the crime scene. If it involves situations that require inspection of surveillance, it is time for Liu Tianqi to take the stage.

Twenty minutes later, Huang Ke wiped the sweat from his forehead and signaled that others could come in.

Zhou Jiaxin walked towards the corpse with an anatomical tool.

The corpse head was facing the living room and his feet were facing the bathroom. A fruit knife was inserted into her abdomen. One of her hands was holding the hilt, as if she wanted to pull the knife out.

Zhou Jiaxin lifted the deceased's white pajamas. There were three stab marks on the abdomen of the deceased and one cut mark. Zhou Jiaxin inferred that the fatal injury was the knife mark about 5cm long on the abdomen of the deceased, gently pressing the wound, and dark red blood stains flowed out, and the internal organs inside were clearly visible.

This is a murder case of an extremely bad nature. The deceased was stabbed by the murderer four times, one of which cut the deceased's abdomen.

Zhao Hao came out of the master bedroom, shook his head and said, "It's not a robbery. I found a laptop, tablet, mobile phone and other electronic devices in the bedroom of the deceased. Moreover, the 800 yuan cash in the deceased's bag was not taken away. This should be a vendetta."

Zhou Jiaxin's preliminary autopsy has not been completed yet. She took off the pajamas worn by the deceased and planned to look at the corpse chart.

The deceased was wearing a white pajama suit, without any underwear inside. Zhao Hao lay on the ground and sniffed the corpse, and then sniffed the deceased's hair.

“The smell of roses.”

"Oh, by the way, I forgot to say it just now. I just went to the bathroom and found that the bath water in the bathtub had not been released yet, and the layer covered with rose petals."

Zhao Hao pinched his chin and began to think:

The deceased did not wear underwear, which means she had already taken a shower and changed into pajamas. The cinema usually gets off work late, and the time to get home from get off work and take a shower is at least around 12:30 am.

Since this house is not a shared house, and only the deceased lives alone, there are only two ways to kill someone in the house.

One is knocking on the door, and the deceased opened the door and let the murderer enter.

The second is to climb the window. This is the second floor, so it is easier to climb in from outside.

Zhao Hao prefers the former because the deceased was killed in the early morning. If someone knocked on the door at this time, it would be suspicious. The deceased would definitely look through the cat's eyes to see who was knocking on the door.

If she is a stranger, she will definitely not open the door. If she is an acquaintance knocking on the door, it is also suspicious to appear in front of her house at this point in time.
