Two hours later, Cui Qishan returned.

At this time, the tea in front of Jiang Yuan had been replaced with coffee. Wei Shiyan next to him was still shaking his hand grinder with the "Purple Dog" Purple Dog.

Cui Qishan looked bad and said, "It's really an Oriental train."

Liu Jinghui's lips curled up, not surprising at all, and said, "Tell me in detail."

Cui Qishan sighed: "The wives of two married men have provided absenteeism for their husbands. We have also asked specifically for those with children, and they were all at home on the day of the incident."

Although the absent evidence given by close relatives is very weak, the criminal police team needs to consider this possibility when inquiring more details.

Cui Qishan continued: "In addition, the motive question raised by Director Liu. Both men admitted that on the day Martina arrived, she was invited to drink and had sex with her."

The two supported each other, and the probability of perjury was relatively low. Most importantly, after hearing about the murder,

They all admitted cheating neatly, which made the saying "murder to cover up cheating" lose the market.

Jiang Yuan, Liu Jinghui and others understood the joints and nodded slightly.

Judging from Cui Qishan's current investigation, the suspicion of these two men is already very low.

Cui Qishan finally concluded: "In this way, the footprints of four people found in Martina's apartment, and two male residents who were confirmed to be suspected, are likely to be out of suspicion. The other two, we are asking Avi Airlines staff through surveillance videos. These foreigners are not very cooperative, and it may take some time."

"There are their facial recognition information on the border inspection." Liu Jinghui asked.

"The clarity is not enough. Because they were all taken at night, they are not on the front face." Cui Qishan said and looked at Jiang Yuan. "Image enhancement is also very slow. If it is not on the front face, it may not be able to match." Jiang Yuan said as he stood up and said, "I'm going to go to the scene first. You can ask the director of Awei Airlines first. If I get in touch, he should be a sensible person. If not, I will help you with image enhancement."

"Is it appropriate to find Awei's senior management directly?" Cui Qishan gave a brief reminder.

In terms of social experience, Cui Qishan is more than three levels higher than Jiang Yuan, but his strength is limited and he cannot allow him to move around casually.

Just by hearing what Jiang Yuan said, Cui Qishan knew that Jiang Yuan wanted to use the Avi Airlines crash and Martina's murder to threaten the Avi Airlines directors and ask him to give orders to get the cooperation of Avi Airlines staff.

It is easy to say that the case was linked during the investigation stage, but the director of Awei Airlines was obviously not Xiao Baicai, the old man had his own background and supporters.

When talking to such people, such as the criminal police at Cui Qishan, most of them hope to come and go well. If they really want to merge the case, it is naturally the saying of merge the case. If it is just a threat, it doesn’t have to.

Countries like Myanmar or Italy require them to invest in monitoring equipment and facilities in units of billions, and invest in corresponding databases and monitoring systems in units of billions, and then train and add map detective police based on local personnel standards. Finally, when it comes to specific cases, it is completely difficult to conduct surveillance reading in units of hundreds of people, which is completely difficult.

It can be said that the development of world criminal investigation technology, especially the development of Chinese-style criminal investigation technology, is a template that most countries cannot copy, but the development of world criminal technology is not subject to the will of small countries.

There are very few countries where the dark web system and virtual currency transactions can be handled in a comprehensive manner by 3D printed metal-free firearms, new explosives and new drugs that have become a large-scale dark web system and virtual currency transactions.

Therefore, the decline in the level of public security is universal in real world. For example, theft and robbery that Europe criticizes is just a superficial phenomenon, and what it cannot maintain is more than public security. On the contrary, the United States is able to maintain the level of public security without regressing, which itself represents a considerable degree of progress.

For the current criminal police officers of Zhengguang Bureau and Ningtai County Bureau, first try the simple model. The default case is an ordinary case, which is the most reasonable choice.

until.-

In the afternoon, Cui Qishan brought back frustrating news that made Liu Jinghui excited:

"Through inquiry about residents in Avi's apartment, the identity of everyone entering and leaving the apartment within two days has been confirmed. After calling one in turn, the identity of the other two has been confirmed. One is Avi's partner, 34-year-old Austrian; the other is a pure friend, a researcher at the Beijing Institute, a Belgian. Martina once took him to Avi's party."

Cui Qishan paused for a moment and then said, "The two of them have evidence of absenteeism, and the surveillance near their residences proved,

After the two went home that evening, they didn't go out the next morning, and the location of the mobile phone given by the technical detective was also in line with the same."

Jiang Yuan became meditated when he heard this.
