National Forensic Doctor

After the autopsy was completed, Jiang Yuan cleaned himself up and returned to the office building of the Criminal Police Brigade of Zhengguang Bureau.

It was already three hours later.

The criminal police from the Zhengguang Bureau and the Jiang Yuan case-handling team were sitting in the conference room, having already thought through the case.

Hearing that Jiang Yuan was coming, Tao Lu also calculated the time and came to the conference room, sitting down to listen to the case together.

Tao Lu first asked: "What is the attitude of Avi Airlines? Have the victims' families contacted you?"

No matter which dynasty it is, the cases are different whether there is a victim or not.

Not to mention those cases that were successfully completed, let’s look at those wrongful convictions that were overturned. Behind them, either the victim’s family members refused to let go, or the police officers or other people involved in the case refused to give in, and only then could the cases be reversed.

The pressure of handling the same cases involving foreigners, Burmese and Italians is obviously different.

The case was handled by the Fourth Squadron. Xiao Si immediately stood up, saluted, and said, "The lawyer of Avi Airlines contacted us to inquire about the situation. After we responded, there was no news. The victim's family did not contact us."

"Like this." Tao Lu couldn't help but feel a little surprised.

Cui Qishan knew what Tao Lu wanted to ask, so he coughed twice and said, "Avi Airlines is probably a little worried as well."

Tao Lu looked over.

Cui Qishan quickly continued, "The crime scene, that is, the apartment where the victim lived, was provided by Avi Airlines to its own employees. From the surveillance video, the victim returned to the apartment at around 9 o'clock that night and did not go out again. There is no surveillance inside the apartment, but there are surveillance cameras on the door and the outer wall of the apartment, so the criminal is likely to live in the apartment."

Tao Lu couldn't help but raise his head: "How many people live in the apartment?"

"28 households, 46 people." Cui Qishan answered in both whole and small numbers: "They are all employees of Avi Airlines and their families, most of them are foreigners. There are 38 foreigners. In addition, there are several children."

Tao Lu immediately understood and said, "The criminal is one of their own, no wonder—"

"That's about it." Cui Qishan said with a chuckle, looked at Jiang Yuan, and said, "I took the footprints of the scene, Captain Jiang, please take a look."

"Okay." Jiang Yuan didn't have any reason to be hypocritical. The cooperation with the Zhengguang Bureau was originally a long-term one. Besides, since he was already here -

Cui Qishan was familiar with Jiang Yuan's habits and was well prepared. With a wave of his hand, his men quickly released the photos of the footprints taken at the scene.

When the room is paved with tiles, it is relatively difficult to identify footprints. If there is a lot of dust in the room or the soles of the shoes are dirty, it is not so difficult. If not, many traditional footprint extraction methods are not so effective.

Footprint extraction is essentially the same as fingerprint extraction. The simplest solution is to sprinkle powder and then use tape to extract it. However, most humans wear shoes when walking, resulting in less sweat and other components in the footprints, which makes it more difficult to leave traces.

Fortunately, the Zhengguang Bureau could afford a "laser footprint detector". Although it was difficult to extract, many footprints were still extracted, most of which were barefoot.

"Roughly speaking, there are more than five people in this room." Jiang Yuan looked through all the more than one hundred photos of footprints and said, "One person wearing shoes, Martina herself, and three or more other men."

"Fortunately, there was no party." Cui Qishan was not surprised, and continued: "Martina flew here from Italy. I have collected the footprints of the people who were in the room that day. I will show you the male footprints first? There are also footprints of people who entered and left the apartment in the past two days. We haven't collected all of them because many of them are foreigners and we don't have relevant data."

The corners of the eyes of Maki Zhiyang and others twitched. Some second-generation people may look harmless, but you don't know what they are doing in private.

Comparing footprints is also difficult, especially when the shoes are different. Often we can only make a rough comparison first and then compare them in detail.

Jiang Yuan asked everyone to continue the discussion while he looked at the footprints for a long time. Finally, he wrote two names on a piece of paper.

"The man wearing shoes is also a man, but he is not a resident of the apartment. The identity of the other barefoot man is also uncertain." Jiang Yuan said as he handed Cui Qishan a note with simpler parameters such as height, weight and age.

Cui Qishan quickly put it away, and said with a sigh of relief: "In this case, the murderer must be these two people who found out the identity. It's not that difficult to choose one of the two."

Judging from the time of death, when Martina died, there were only residents in the apartment, and the residents' footprints were collected. In this case, the murderer should be among these two residents.

As for the owners of the footprints of the two non-apartment residents, they were most likely those who had entered and exited Martina's apartment before. If the murderer could be found directly, there was no need to delve into their identities.

Xiao Si, who was standing next to him, added coldly: "If we are unlucky enough, it is possible that the murderer did not leave any traces."

Xiao Si was one of the cold-faced, foul-mouthed, and ignorant criminal policemen abandoned by the Seventh Brigade and finally taken in by the Fourth Brigade. Cui Qishan, the captain, took office late, and it was rare to have a position in the capital. In addition, Xiao Si did have some ability, so he had to stay in the team.

After staying for a long time and being beaten many times, Cui Qishan didn't care. He just said, "It's not easy to kill a person. It's strangled to death. It's difficult to leave no traces. Can the footprints around the house explain who the murderer is?"

Cui Qishan still asked. What Xiao Si said was indeed possible.

Jiang Yuan shook his head: "The deceased died in bed, and the sheets were pulled under the bed. There are no footprints. We can try to find evidence with trace evidence, or see if there are any residues such as dandruff."

Cui Qishan agreed, then looked at Tao Lu and asked, "Do you want to bring the two people whose footprints match the original for questioning first?"

These are common analyses in handling cases, and there is nothing special about them. If there is anything special, it is that both the victim and the suspect are foreigners.

However, this is not a very uncommon thing for the current police detectives. They just have to follow the rules.

Now there is evidence that the two people have been in and out of the deceased's apartment, so it is only natural to call them to the house for questioning.

Tao Lu agreed after thinking about it, and only reminded him: "Collect more relevant information and witness testimonies. Do the two people live alone or with others?"

This involves whether there is an alibi. Before Cui Qishan could look through it carefully, Xiao Sixian next to him said, "Both are married men, one lives with his wife, and the other has a wife and two children."

"Two married men ran into a single woman's apartment." Tao Lu shook his head: "I'm old and can't keep up with the times. You should take statements from the wives of the two men separately and ask them carefully to prevent them from perjury."

"Yes." Cui Qishan stood up.

"People involved in the case are not allowed to leave the country. Please make it clear to them when you are taking their statements. Don't think that you can just walk away and never come back after giving false testimony." Tao Lu reminded them clearly.

Liu Jinghui finished reading the relevant information, raised his head and said: "We still have to pay attention to the motive.

These two people, the two men who left footprints in the victim's room, were both in their 30s. Their jobs were basically unrelated to Martina's. One of them was an engineer, and the other was in charge of logistics-related business.

They are all married, what is the motive for the murder?"

"Because they cheated, they were threatened, or they were afraid of being caught, and they were afraid of losing their wealth and a lifetime of child support?" Cui Qishan gave an answer casually.

"It's hard to strangle someone to death." Liu Jinghui used Cui Qishan's words just now and said, "It's hard for ordinary people to kill so decisively."

Cui Qishan did not object, but smiled and said, "You have a point, but if it wasn't one of these two people who killed him, it would be difficult to find the murderer in the apartment building. This is the Eastern Train Murder Case."

Liu Jinghui smiled gently.
