I have been in the crime team for these years

Chapter 22 The Strange Cause of Death

Gao Qiang came to the bedside, reached out and touched the quilt, and couldn't help frowning: "The quilt is cold, and the person is no longer in the room."

Ren Tianya came to the balcony, but the balcony was separated by a security net, so he couldn't go out.

Looking at the bathroom door, the door is closed.

A police officer came over, reached out and twisted the doorknob, but could not open it.

The police officer shouted: "Captain Gao, the bathroom door is locked, the suspect may be hiding in the bathroom."

Gao Qiang strode from the room to the bathroom door and shouted: "Bao Xuehui, open the door quickly! You can't escape."

Nothing happened in the bathroom.

"That's not right!" Gao Qiang's expression changed, he raised his leg and kicked hard at the bathroom door. With a bang, the door opened.

In the bathroom, I saw Lan Zaihui lying naked on the floor, and the bathroom nozzle was still spraying hot water.The gas water heater hanging on the wall is still burning.

The whole bathroom is damp and stuffy.

"Team Gao, it seems that Lan Zaihui died of carbon monoxide poisoning." After taking the photo, a police officer looked at Lan Zaihui's stiff body on the ground and said to Gao Qiang.

"Dark purple spots have appeared on the corpse, and it is estimated that he has been dead for at least eight hours." Ren Tianya scanned the corpse and quickly made a judgment.

Under normal circumstances, a small area of ​​dark red corpse spots will start to appear one hour after death, and after more than ten hours, it will spread to the whole body and turn dark purple.

"No wonder the quilt on his bed was cold when I touched it just now. It turned out that he died while taking a bath last night." Gao Qiang thought thoughtfully. .Run around carefully to see if there is any clue."

After Gao Qiang finished speaking, he took out his mobile phone and called the forensic doctor to come over immediately.

Several police officers have begun to check around.

Ren Tianya looked at the bathroom, but saw that the window was closed, so he tried to close the door again, and it was closed tightly, with only a small gap under the door.

Bathing in such an environment can easily cause carbon monoxide poisoning and death.

Is it really too closed when taking a shower, which leads to a large amount of carbon monoxide poisoning and death?

But the weather is not too cold now. With Lan Zaihui's physique, he is not so afraid of the cold that he has to close the doors and windows, right?
Ren Tianya went out of the bathroom, checked on the balcony for a while, and then went back to the room to look around.

Gao Qiang also looked around the room.

"Captain Gao, nothing was found in the bathroom, and no other person's footprints and fingerprints could be extracted at the scene." Two police officers came out of the bathroom and reported to Gao Qiang.

In the misty bathroom, even if someone came in, footprints and fingerprints could not be extracted.

"Team Gao, nothing else was found on the balcony and room, everything is normal." Two other police officers also reported to Gao Qiang one after another.

Gao Qiang paced back and forth in the room, his thick eyebrows slightly furrowed: "Is it really an accidental death caused by taking a bath?"

Just as he was talking, Forensic Doctor Liu hurried over with an assistant carrying a box.

Ten minutes later, Forensic Doctor Liu came out of the bathroom.

"After a preliminary examination, the deceased died of carbon monoxide poisoning. The time of death was around [-]:[-] to [-]:[-] last night. However, the specific cause of death needs further autopsy."

"Looks like he died of carbon monoxide poisoning while taking a shower. How could it be such a coincidence?" Gao Qiang punched his palm, feeling very depressed.

After finally finding clues to Guan Jian, he didn't expect that another accident happened to Lan Zaihui.

Although no stolen jewelry was found in the house, the suspicion that Lan Zaihui was the robber cannot be ruled out.

But now that Lan Zaihui is dead, all this can no longer be investigated.

"Wait a minute." Ren Tianya seemed to have remembered something, and rushed into the bathroom quickly.

He came to the dead body of Lan Zaihui in the bathroom, squatted down, turned over the body's head with gloved hands, and examined it carefully.

There was obviously a bruised and swollen lump at the temple on the left side of the head.

"What's wrong? Did you find anything?" Gao Qiang quickly followed in and asked Ren Tianya.

"There was a bruise on the head of the body."

As Ren Tianya said, he came to the bathroom window again, opened the window, and took a closer look at the edge of the window sill.

The edge of the window sill is clean.

A smile appeared on the corner of Ren Tianya's mouth, and then he looked under the window again.

A sewer pipe with a diameter of more than ten centimeters passed about fifty centimeters from the bathroom window.

This is the drainage pipe for the toilets on the second and third floors.

Forensic Doctor Liu said: "I have just examined this bruise. It is facing the ground. It should have been injured by the deceased hitting the ground when he fainted."

This explanation is very reasonable. On the hard tiled floor of the bathroom, if a person falls down and hits the ground first, he will definitely be injured.

Ren Tianya turned his head, shook his head and said, "No, it's not that the deceased was injured on the ground, but someone threw a stone from outside."

"Injured by the stone?" Gao Qiang walked quickly to the window.

"Team Gao, look" Ren Tianya pointed to a sewer pipe outside the bathroom window, "If the murderer climbed from the sewer pipe to this position, it would be right in front of the bathroom window. If you are good at it, you can climb into the bathroom along the pipe. Come."

Gao Qiang came to the window, stuck his head out to take a look, and nodded: "Yes, if people with good climbing skills can indeed climb here along the sewer pipe and grab the edge of the window, they can climb to the bathroom window sill. Come up."

There was a hint of a smile in Ren Tianya's eyes: "So, we can assume that if the murderer had already climbed up the sewer pipe, hid himself outside the window sill, prepared stones, and hit him with stones when Bastard Hui took a bath. If you hit Lan Zaihui's head, Lan Zaihui will definitely fall to the ground."

"Also, Captain Gao, look, this window sill is too clean."

Gao Qiang stretched out his hand and touched it gently on the edge of the window sill. When he looked at his fingers, there was no dust at all.

He immediately understood what Ren Tianya meant.

Generally speaking, no one will clean the window sill outside the bathroom window frequently, unless someone with mysophobia does so.

And for someone like Lan Zaihui, who doesn't even want to clean up his own room, how can he wipe the outside of the bathroom window clean?

"So, someone deliberately erased the marks on the window sill, for fear that the police would find the hand and footprints left on it."

If it weren't for a person with extremely strong and meticulous observation and reasoning ability, he would never have deduced the almost perfect murder designed by the criminal.

"Captain Gao's warning!" Ren Tianya gave a thumbs up and lost no time in flattering Gao Qiang.

A policeman interrupted, "But isn't the window closed?"

Gao Qiang shook his head: "No, the window wasn't closed originally, but the murderer knocked Zaihui unconscious with a stone, then climbed in through the window, threw the stone out, and then he came out of the window, closed the window, and followed Escape through the sewer."
