What is Water? Water is the source of all things, and water is life.

There is also a joke about water. In a group full of highly educated people, the question of whether a drop of water falling from a height of 10,000 meters will kill people. An aunt suddenly popped up and said, "Have you ever been in the rain?" Then, the whole group fell silent, and then the aunt was kicked out of the group......

Our case started with a rainstorm.

Do you believe that raindrops can kill?

At 9:32 p.m. on September 4, 2009, a man in his thirties walked briskly down an empty street with a smile on his face and flowers in his hand.

Suddenly, the wind blew and the rain poured down. Li Qing hurriedly looked for a place to hide from the rain. He then walked into the blind spot, appearing thirteen seconds later, but his walking speed became slow and weak, and he soon collapsed in the rain...... Red blood flowed from his upper body, mixed with rain, staining half of the street......

September 6, 4:16 p.m., Beicheng Public Security Bureau.

Criminal investigation expert Pan Lei and deputy Huang Liya couldn't help frowning after watching the above video of the surveillance room.

"What happened next?" Huang Liya asked.

"He's dead." Criminal police captain Jiang Xun replied.

"Are there any surveillance cameras in other directions? So what's going on in the video blind spot? Huang Liya asked.

"There are no other surveillance cameras," technician Xiao Song shook his head, "The next surveillance camera is two thousand meters away, and the rain is so heavy that you can't see anything at all." ”

"In fact, I am very lucky to be able to find this surveillance video, after all, it is heavy rain and night. The original video is black, and we can only see the human form, and it is already our limit to be able to use existing technology to repair it like this. Another technician added.

"Are there any eyewitnesses?" Huang Liya then asked.

This time it was a police officer named Dong Yu who answered: "No, when Li Qing died, that street was empty, and there was no one." ”

"The situation was special that day, not to mention this street, most of the people in the city were at home watching the live broadcast of the "Super Girl" finals that night." Dong Yu's female partner added.

"Where's the nearby shop?" Huang Liya asked.

Jiang Xun shook his head: "I've checked everything, the shop owner, the five diners, and the residents who may see it around have all checked, and I haven't seen anything, except for the sound of rain, I haven't heard anything." ”

"Where did he buy the flowers in his hand, and who did he give them to?"

"I know this," a female police officer handed Huang Liya a business card, "this is the shop, the owner is a woman, very beautiful." At that time, when Li Qing went to buy flowers, she asked Li Qing who to give them to. Li Qing replied, "It was given to his wife." But then we asked his wife, who was not there that day, but was on a business trip thousands of miles away in Beijing. ”

Pan Lei and Huang Liya couldn't help frowning.

"Can you tell us about Li Qing and his network?" Pan Lei raised his head and asked.

Jiang Xun didn't even read the information, and said directly: "Li Qing, male, 181 (cm) tall, 32 years old, according to our visit, he is smart and capable, kind to others, and is very good at the boss of a Japanese foreign company executive." His wife's name is Liu Ting, 27 years old, she was originally a doctor, and she should be a fashion designer after marrying Li Qing. Most of Li Qing's friends are Japanese, and they have also made preliminary inquiries, but there is not much useful information. No matter how detailed the information is, it's all in the data tape, and you'll see it later. ”

"What does the autopsy report say?" Pan Lei asked again.

"It's a bit complicated, Li Qing has a total of two fatal injuries on his body. There are strong traces of corrosion below the head, which are found to be caused by concentrated sulfuric acid. Another fatal wound was that his entire heart was missing! The method of the person who took his heart is rare in the world, and it is terrible that the heart can be completely removed without harming other blood vessels and internal organs with only one incision on the skin. I'll take you to the morgue when the meeting ends, and I'll explain it as you watch. Forensic doctor Tang He said, but there was a burning heat in his mouth.

"Good. Is there something wrong with the clothes of the deceased? Pan Lei asked again.

"The tests were done and no problems were found. He had nothing on him, except for his mobile phone and keys in his trouser pocket. ”

"Are there any other fingerprints on his clothes?" Pan Lei continued to ask, but his brows furrowed.

"No, all of them have been tested, and no other people's fingerprints have been found." Forensic doctor Tang He shook his head again.

"What about mobile phone communications?" Huang Liya asked Xiao Song.

"The phone is soaked in water, and the communication card is broken. After contacting the mobile company, only a few numbers were called, all of which were the phone numbers of relatives who had already been investigated. Technician Xiao Song said.

"Okay, my last question, do you have his Taobao account here? Or a shopping history? Huang Liya asked.

The two technicians tried each other, and Xiao Song said, "No, but we can communicate with the relevant departments and call up his shopping records." ”

"How long will it take?"

"Tomorrow afternoon at the latest, if it's okay, I'll send it to your QQ in the form of a picture."

"No problem, you remember my QQ, 4011****." Huang Liya finally said.

"At present, there are three suspicions in our investigation: one is Li Qing's date, and the other is what happened in the 13 seconds in the blind spot of the surveillance video. Three, who poured sulfuric acid? Was it really the rain? Or is it the same person who took the heart and the person who threw sulfuric acid? Actually, I personally prefer to have a second perpetrator. It's a pity that with our current capabilities, there is really no way to investigate. As a student of Mr. Pan, I feel guilty! Jiang Xun said, his face full of helplessness.

Pan Lei picked up the information bag and said lightly: "It is the teacher's duty to stand up for the students. Later, I'll go to the forensic lab to see the body, and then I'll go out to investigate. ”

Captain Jiang Xun stood up and shook hands with Pan Lei again: "Teacher Pan! It's up to you! We will cooperate with you here! ”

"Well, rest assured! Duty, Tang River Forensics, let's go. ”

Beicheng Public Security Bureau, morgue.

There's already a corpse lying here. His skin was badly corroded and pitted. Only one head is complete, but there is a shallow smile on the face, like a smile on the surveillance.

"This is an incision of 5 centimeters below the ribs, and the murderer should have reached into Li Qing's chest from here to take the heart," Tang Heyi exerted his strength and opened the chest cavity that had already been disemboweled, "From these cracked blood vessels, I can vaguely identify the path of the hand into the chest cavity from the outside." Now this is where his heart was located, and all the blood vessels that connect to it have been neatly severed. These two pieces of evidence are enough to rule out the possibility that Li Qing committed suicide. ”

Pan Lei circled around the corpse and said, "What an amazing means! Steady and ruthless, bold, careful, and fast. Turn it over and look at the back again. ”

Tang He forensic doctor followed his words, closed Li Qing's chest again, and then turned the body over with Pan Lei.

Behind Li Qing, there is also a corroded "lunar surface".

"Student Huang, come here, let's see what clues are there?"

Huang Liya covered her nose, came up, and looked at Li Qing's back carefully, nine times...... Or nothing.

Or Lao Pan's sharp eyes, in the position of the heart directly behind the heart, saw the "い" symbol.

"What kind of symbol is this? A diagonal hook plus a little? Huang Liya asked curiously.

Pan Lei thought for a while and said, "This is, Japanese." It should have the other half of the す,And い together is the meaning of water.。 ”

"Could it be? Li Qing's whole body was corroded, was it really because of that rainstorm? Huang Liya said in surprise.
