Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Chapter 1145 Bloodstains in the Cracks of the Bathroom Floor

This knife clearly showed signs of having been cleaned. Although the notch on the blade was caused by cutting bones, no blood stains were found on it, so the knife may have been cleaned.

In this case, if you want to find some clues on it, it will not be possible with ordinary means.

After putting away the kitchen knife, Lu Chuan continued his investigation and the first place he entered was the kitchen.

Wang Hong's house has two bedrooms and a living room. The dining room is on the right after entering the door, and the kitchen is further in. There is a wooden door between the kitchen and the dining room.

"Has your family cooked these past two days?"

Wang Dongtian shook his head.

"Wang Hong hasn't cooked much since the divorce. She either eats at work or eats takeout. He rarely cooks at home. The same goes for Wang Lili. Neither of them eats breakfast at home, so the kitchen is pretty much the same as it was when we arrived. Nothing has been moved."

Although Wang Dongtian and his team did not find any valuable clues during this week, they still had a clear understanding of the basic situation.

We also know a lot about the daily living habits of Wang Hong and Wang Lili.

Moreover, some of the utensils in the kitchen were still in their original positions and had not been moved. Apart from boiling water at home, Wang Hong and Wang Lili rarely moved other things in the kitchen.

After Lu Chuan nodded, he opened the refrigerator next to him. Indeed, there were no vegetables or meat in it, but there were some drinks.

There are no frozen ingredients in the freezer, so the entire refrigerator can be said to be empty.

It would be easy if he came. Lu Chuan came to the sink.

Directly open the cabinet under the sink and first prepare a larger collection bag, then start dismantling the elbow under the sink drain.

Wang Dongtian knew what Lu Chuan meant as soon as he saw it.

If the kitchen knife had been used to chop something, where would the other party clean it?

It's most likely in the kitchen sink.

Lu Chuan now opened the elbow, obviously to take out the remaining contents inside for evidence identification and analysis.

The curved nature of the elbow will store some things that are not easy to be washed away, so even if the time is relatively long, or if there is a murderer and the murderer flushes with a lot of water, some physical evidence may not be washed away.

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, there is only one relatively small window on the kitchen side, and the room is still quite dark after it is blocked.

Therefore, using ultraviolet light, we 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, so Lu Chuan did not do them himself. Instead, he asked others to help. After all, there were still other places that had not been surveyed.

Off the bedroom are two more bedrooms.

Wang Hong sleeps in the master bedroom on the sunny side, and Wang Lili usually sleeps in the second bedroom opposite.

"Nothing in the second bedroom had been moved. When we came, we didn't find any signs of excessive disturbance in the second bedroom."

Wang Dongtian said on the side. Indeed, as Wang Dongtian said, the entire second bedroom looked relatively clean. There were no wrinkles on the neat bedding, which was obviously carefully taken care of, and there was no debris on the floor.

At the same time, there was no sign that the simple wardrobe had been opened.

There were two drawers of the bedside table next to it that had not been opened. Lu Chuan had read the file carefully and knew that Wang Lili's bank card was found at the bottom of the drawers.

The situation was different when leaving the second bedroom and entering the master bedroom. The master bedroom was already in a mess, and Wang Hong was not asked to clean it up at that time.

In fact, Wang Hong only slept at home for three nights. She usually had to work night shifts, so the police did not ask her to move, and she really did not move anything.

Of course, since Wang Hong had been in the room after the incident, some of the information collected was not so accurate.

Lu Chuan focused on observing some of the separated drawers and tried to see if he could find any fingerprints on them.

In fact, the Tianshan District Criminal Police also focused on this during the first on-site investigation, but they did not find much.

Lu Chuan was just a little worried, so he checked again and found that it was indeed the case. The other party was experienced, or rather cautious. He must have worn gloves when searching for things, so there were not many traces left. Of course, it was possible that he had wiped it again later.

After the inspection of both bedrooms was completed, the most important place was the bathroom. Lu Chuan intended to leave this small space for last.

The main reason is that if the murderer really did the worst as Lu Chuan, Wang Dongtian and others expected, and killed Wang Lili and dismembered her body here, then this bathroom would most likely be the final location where the body was dismembered.

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 outside.

Starting from the bathroom door, Lu Chuan began to check inch by inch.

Lu Chuan checked every gap between the bricks and picked them all up.

According to the files, during the first on-site inspection, the bathroom was only skipped because the inspection was only conducted according to the standards of a theft case.

Therefore, the investigation on the bathroom was basically blank. Lu Chuan's second investigation on the bathroom can be said to be the first investigation.

In fact, Lu Chuan soon found some clues in the bathroom, and they were important clues.

In the crack in the ground, there was an obvious brown substance on some of the debris that Lu Chuan dug out. Based on Lu Chuan's experience, this was definitely dried blood.

Wang Dongtian and others later also apparently saw these things. It seems that this case has been confirmed to be a criminal case.

On the way, I carefully put these substances into the evidence collection bag and continued to investigate the bathroom. I found something in the angle between the bathroom door and 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 conducted a detailed inspection of the entire bathroom, not leaving out a single inch. It was just a small bathroom, but Lu Chuan was busy for nearly an hour.

The gains in this one hour were enormous, proving that this case was a criminal case.

After killing the person, the murderer probably dismembered the body in the bathroom and put it in the suitcase.

At the same time, the other party cleaned the scene with a bathroom mop.

The dried blood on the back of the bathroom door and the marks on the mop matched, which was proof enough.
