Chapter 1145 Blood stains in the cracks in the bathroom floor
This knife obviously has signs of cleaning. Although the gap in the curled blade was formed by chopping bones, no blood was found on it, so The knife may have been cleaned.
In this case, if you want to find some clues on it, it cannot be done by ordinary means.
After putting away the kitchen knife, Lu Chuan continued his investigation. The first thing he entered was the kitchen.
Wang Hong’s house has a layout of 2 bedrooms and 1 living room. After entering the door, there is the dining room on the right hand side, and further inside there is the kitchen. There is a wooden door between the kitchen and the dining room.
"Have you cooked at home these two days?"
Wang Dongtian shook his head.
“Wang Hong hasn’t cooked much since her divorce. She either eats at the company or eats takeout. He basically doesn’t get angry at home, and the same goes for Wang Lili. Neither of them eats breakfast at home. So the situation in the kitchen is almost the same as when we came. "
In the past week, although Wang Dongtian and the others have not found any valuable clues, they still have a clear understanding of the basic situation. of.
We also know a lot about the daily living habits of Wang Hong and Wang Lili.
Moreover, some of the utensils placed in the kitchen have not been moved in their original positions. Wang Hong and Wang Lili rarely touch other things in the kitchen except for boiling water at home.
After Lu Chuan nodded, he opened the refrigerator next to him. It was true that there were no vegetables or meat in it, but there were some drinks.
There are no frozen ingredients in the freezer compartment, and the entire refrigerator can be said to be empty.
It will be easier if it comes. Lu Chuan came to the vegetable sink.
To directly open the cabinet under the sink, first prepare a larger collection bag, and then start to disassemble the elbow under the drain of the sink.
Wang Dongtian knew what Lu Chuan meant when he saw it.
If something had been chopped on the kitchen knife just now, where would it be cleaned when it was cleaned?
It's probably in the sink in the kitchen.
Lu Chuan now opened the elbow, obviously to take out the remaining things inside for physical evidence identification and analysis.
Because of the bending characteristics, the elbow will store some things that are not easily washed away, so even if it takes a long time. In other words, if there is a murderer and the murderer washes it with a lot of water, it may not be able to wash away some physical evidence.
After doing all this, Lu Chuan took the ultraviolet lamp and started scanning everywhere in the kitchen.
Because Wang Hong's house is relatively old, the layout of the kitchen only has a relatively small window. After blocking it, the room is still relatively dark.
So using ultraviolet light, you can find some clues even in the daytime.
Some fingerprints were found on the sink and the refrigerator. Lu Chuan told the modern criminal police of the Tianshan District Criminal Police Brigade to collect these fingerprints first.
These tasks were relatively simple. Lu Chuan did not do it himself, but asked others to help. After all, there were other places that had not been explored.
After leaving the bedroom there are two bedrooms.
Wang Hong sleeps in the master bedroom on the sunny side, and Wang Lili usually sleeps in the second bedroom on the opposite side.
"Nothing in the second bedroom has been touched. When we came here, we didn't find too many signs of turning over in the second bedroom."
Wang Dongtian said from the side. Indeed, as Wang Dongtian said, the entire second bedroom looks relatively clean. There were no wrinkles on the neat bedding, which had obviously been taken care of carefully, and there were no clutter on the floor.
At the same time, the simple wardrobe has no trace of being opened.
There are two bedside table drawers nearby that have not been opened. Lu Chuan has read the file carefully and knows that Wang Lili's bank card was found at the bottom of it.
After leaving the second bedroom and entering the master bedroom, things were different. The master bedroom had been turned over and became quite messy. Wang Hong did not let Wang Hong clean up the situation at that time.
In fact, Wang Hong only slept at home for three nights. Normally, he had to work the night shift, so the police did not let her move. She indeed did not move anything.
Of course, because Wang Hong had been active in the room after the incident, some of the information collected was no longer so realistic.
Lu Chuan focused on observing the separated drawers and looking to see if he could find any fingerprints on them.
In fact, the Tianshan District Criminal Police also focused on this during their first on-site investigation, but they did not find much.
Lu Chuan was just a little worried and checked again. It was indeed the case. The other party was still experienced, or rather cautious. He should have worn gloves when rummaging through things and did not leave much behind. Traces, of course. Maybe it was wiped again later.
After the two bedrooms have been surveyed, the most important location is the bathroom. Lu Chuan deliberately left this small space for last.
Mainly because if the murderer really followed the worst expectations of Lu Chuan, Wang Dongtian and others and ended up killing Wang Lili and dismembering her body here, then this bathroom would most likely be the final destination for the dismemberment of the other party. Place.
The room was built twenty or thirty years ago, so the bathroom was very small. When Lu Chuan came in alone, everyone else could only watch from the outside.
Starting from the bathroom door, Lu Chuan began to check inch by inch.
Lu Chuan didn't let go of any cracks in the bricks and picked them all up.
Judging from the file, during the first on-site investigation, the bathroom was just skipped because the investigation was only based on the standards for theft.
So the survey about the bathroom is basically blank. Lu Chuan’s second survey of the bathroom can be said to be his first survey.
In fact, Lu Chuan soon discovered some clues in the bathroom, and they were major clues.
In the cracks in the ground, some of the debris that Lu Chuan took out had obvious brown substances. Judging from Lu Chuan's experience, this was definitely dried blood.
Wang Dongtian and others obviously saw these things later. It seems that this case can be determined to be a criminal case.
On the way, he carefully put these substances into the evidence collection bag and continued to investigate the bathroom. He found something behind the bathroom door and in the corner of the wall.
Standing up, Lu Chuan picked up the mop next to him, measured it according to the mark, and then put the mop back.
Then Lu Chuan inspected the entire bathroom in detail, not missing an inch. Lu Chuan was busy working on just a small bathroom for nearly an hour.
The harvest in this hour was huge, and it was verified that this case was a criminal case.
After the murderer finished killing the person, he probably dismembered the person in the bathroom and put it in the suitcase.
At the same time, the other party used the bathroom mop to clean the scene.
The dried blood stains on the back of the bathroom door and the marks on the mop can be matched, which is enough proof.
