Detective: I can see the criminal record

When Cen Lian was checking the installation locations of these facilities, he was thinking that the problem was most likely not here.

He was very clear about the level of his colleagues in the branch. During the previous investigation, the facilities and installation locations should have been checked in detail. It would be normal if there were omissions in one or two homes, but it was impossible for omissions to occur when investigating in all the victims' homes.

This means that if they do not find any effective clues through conventional investigations, then if they want to find new breakthroughs, they must find ways that they have not considered before.

Cen Lian’s first reaction was to suspect that there was something wrong with the installer.

As the people with the most direct contact, they are the most likely to tamper with the elderly's homes.

The branch had previously investigated the installers, but there were no problems with the equipment itself. During the investigation, all victims said that the installers had no direct contact with them, nor had they touched their phones or asked them to scan codes. They only took photos with their phones at the beginning and end of the installation for acceptance and archiving.

After hearing this, Cen Lian really didn't find any problems.

But whether there is a problem or not depends on what is above their heads.

Cen Lian was thinking this, and while checking the installation site at Wuqiushan, he found photos of the man and woman who were installing the equipment.

The criminal record was hanging over their heads, but it did not make Cen Lian happy.

The suspects he could think of when he took over the case had obviously been repeatedly suspected during the current case, but he had not been able to find a breakthrough in them for such a long time, which meant that their methods of committing crimes were unconventional and difficult to think of during the investigation, or it was difficult to capture evidence.

"That's not the problem." Wu Qiushan simply checked and then shook his head and stood up, "Let's think about the places they haven't checked."

Wu Qiushan didn't think that the problem would lie with these elderly-assistance facilities that were installed and then hastily dismantled. When he stood up and saw Cen Lian looking at the two photos with a thoughtful look on his face, he realized what Cen Lian was doubting.

"These two installers are indeed the most suspicious, but after several rounds of investigation, we have not found any evidence pointing to them." Wu Qiushan said, "Let's check other things in the house."

Cen Lian turned off the screen of his phone and said, "I was wondering, since no one had access to the victim's phone, who borrowed the money? Was it a virus running automatically or was it a remote operation?"

"This suspicion was mentioned in the case file, but no virus was found on the victim's phone," Wu Qiushan remembered very clearly, "but the fact that there is no virus on the phone now does not mean that there was no virus in the past, so the possibility that the victim's phone was infected with a virus in some way to transfer money has never been ruled out."

Cen Lian nodded. If it was a cell phone virus, he might need to go back and ask Qu Zihan to see if she had ever heard of a virus that could be cleared without leaving any trace.

After looking at several installation locations in succession, Cen Lian suddenly looked at the corner of the wall between the bathroom and bedroom door.

Judging from the traces, a handrail should have been installed here before.

On the wall below the installation traces, you can vaguely see traces left by something.

There are scratches on the wall at this location, which looks a little strange.
