She was careful, fearing that the man would stab him with his backhand.
Yun Tuan registered, put the small piece of silk fabric in the bag, looked at it carefully for a few times, and moved his eyes downward.
Xiao Liu cautiously pulled down the hem of the formal dress, "What are you doing? You don't let women go? Is it necessary to be lonely like this!"
"No, I just think these may be fragments of silk stockings." Yun Tuan put the bag into the box and waited for inspection.
Apart from a bed, there is no other furniture in the room, and there is no ceiling fan.
This building is very old. During the renovation, it was only wallpapered on the outside and wooden floors, but no reinforcement materials were installed.
Fingerprints, footprints and tool imprints have been collected by a specialized team.
Even a piece of the damaged wall panel was broken off.
Half an hour later.
Yun Tuan followed the large army back to the laboratory.
The temperature of the air conditioner in the laboratory was set very low. As soon as I changed my clothes, the clouds shivered from the cold.
Xiao Liu gave me a pair of blank stares.
"Go and examine the wooden floor and the remains of the deceased's abdomen. I'll analyze the blood sample. Be careful, it's quite corrosive." Xiao Liu said, with no smile on her jade-like face. She picked up the three
A test tube and headed elsewhere.
Yun Tuan looked at the two bags and the unfamiliar inspection machine in front of him, and kept recalling Jing Yu's previous operations.
...What's the use of remembering it! Just because someone has used it doesn't mean they know how to use it, unless there is really a god to help.
After a few seconds, she abandoned her unrealistic fantasy and turned to studying the equipment.
Fortunately, the various instruction buttons are not marked in foreign languages.
Yun Tuan reluctantly placed a small part of the wall panel on the platform and pressed a series of buttons.
Ding——
There was a vague complaint from the back room: "You are sick! You need fully automatic analysis for such a simple test? That function will cause too much damage to the machine!"
Hearing this, Yun Tuan breathed a sigh of relief. This operation was at least a test, and loss or something was not important.
Five minutes later, the residue analysis report was transmitted to the display screen.
Were the chemical burns on the victim's waist also caused by strong alkali?
She followed the same method and put the extract from her waist and abdomen on the platform.
Yun Tuan carefully recalled that the burns on the waist and abdomen of the corpse were not new injuries. Although they were very serious, they had been treated. Judging from the degree of healing of the edges, it might have been one to two weeks ago.
Just as I was thinking about it, the analysis report popped up.
Hydroxyl, sulfuric acid, hydrogen peroxide...
Yun Tuan frowned as he looked at it - what is it? Can you still live after being exposed to these chemicals?
Looking at the proportion of this residue, she remembered a very dangerous solution.
Piranha solution, also generally called piranha solution, is extremely oxidizing and is used in laboratories to clean glass slides. It can completely remove organic matter on the glass slides. However, it is too dangerous and is prohibited from private preparation.
This property was favored by criminals in the past and used to dissolve corpses.
It is like a corpse-turning water...
Even after such a long time, there are still residues, and the area of the wound is not small. Even if he was not attacked, this person would not live long.
Then there is another question——
Was this person actively or passively exposed to the piranha solution?
At this time, Xiao Liu came out with the test results.
"So fast? Didn't the hospital draw blood in the morning and get the test report in the afternoon?" Yun Tuan pursed her lips, and she found that she really liked the look of this girl who was so stunned that she couldn't hit anyone.
Xiao Liu rolled his eyes, "If the efficiency of handling cases is the same as that of health examinations, by the time we get the results, we don't know how many more victims there will be! You..."
