◎Chapter 22 The Man Who Drinks Urine

There are no signs of breaking into the room, the balcony and windows are guardrailed, and the person is supposed to have entered the room with a key.

The four members of the special case team stared at the captain of the criminal police together, and the captain's gaze was a little evasive, and a trace of panic flashed in his eyes.

"How did we get in, and who is holding the key?" ”

The captain of the criminal police said, "I ...... I haven't been here. ”

Bao Chu said: "Just do a small experiment to prove your innocence, I hope you will cooperate." ”

Bao took out a portable fingerprint scanner from the toolbox. When the police investigated the scene, most of them used powder and spray fingerprint extraction technology, sprinkled fine powder like aluminum powder and titanium dioxide powder on the fingerprints, and brushed them with small brushes, which can often be seen on TV; Rough surfaces such as bricks and rocks are fingerprinted using a chemical spray, which usually contains iodine pentafluoride or ruthenium tetroxide.

Fingerprint scanning technology is a technological achievement in recent years, and agents and central guards on the covert front have miniature scanners that can extract fingerprints from strangers when they shake hands, and connect to a terminal database in just a few minutes to determine the identity of the other party.

Bao Chu first extracted the fingerprints on the cup, and then compared them with the fingerprints of the criminal police captain, the whole process was photographed and recorded by Su Mei, the criminal police captain was very calm, and the comparison results showed that the fingerprints on the cup did not belong to the criminal police captain, it was another person.

Bao Chu said sorry, and the captain of the criminal police said he understood. Bao Shu took out another cotton swab and collected a sample of water from the cup.

Professor Liang said: "Landlord, there may be extra keys. ”

The special case team and the captain of the criminal police knocked on the door of the landlord's house opposite.

The door opened, and the landlord was a very obscene-looking old man, bald, about fifty years old, and his eyes were always quietly glancing at the beautiful waffles as they talked. The landlord claimed that his wife had died and that his 14-year-old son had not returned from school. The captain of the criminal police went straight to the point and asked him if he had any extra keys, and the landlord said that there was another one, and before the two policewomen moved in, the house was also rented to a group of people who were doing pyramid schemes, and later they were banned by the local police station and the industrial and commercial bureau, and they were equipped with a few more keys at that time.

The landlord complained: "Those people still owe me a month's rent, can the government help me get the rent?" ”

Professor Liang asked, "Did you go to the opposite room last night?" ”

The landlord glared and said, "How can I do that?" ”

Bao Chu asked, "What does that mean?" ”

The landlord took out a key from the drawer under the TV and handed it to the captain of the criminal police, who muttered, I haven't done anything, it has nothing to do with me.

Bao Chu then asked, "What haven't you done?" ”

The landlord was angry, he raised his voice and said: "Am I a bad person, you interrogate me, who doesn't know that the two girls on the other side of the door were killed, and they are bare-assed, and the security guards downstairs know that you actually suspect me, I am fifty-one years old, and their rent has not been paid off, as well as water, electricity and property management fees, you have to give it to me, I am unlucky." ”

At this time, the landlord's son came back from school, a pale boy, wearing a school uniform, and looking listless.

Professor Liang pointed to the captain of the criminal police and said to the landlord: It is not easy to want the rent, this is also the leader of the police station, you go to the Municipal Public Security Bureau tomorrow, he will give you the rent, but we need to collect your fingerprints, and we need your cooperation.

The landlord agreed, Bao Chu took out a fingerprint scanner to collect the landlord's fingerprints, Professor Liang coughed, looked at the landlord's son out of the corner of his eye, Bao Chu understood, and stepped forward to collect the landlord's son's fingerprints. The pale junior high school boy didn't say a word, not very reluctantly.

The special case team returned to the room of the two policewomen and immediately compared the fingerprints, but the results were very disappointed, and the fingerprints on the cups did not belong to the landlord or the landlord's son.

This result made everyone very confused, who else could use the key to enter and exit this room?

The special task force plans to go to the community's monitoring room to have a look. The floor of the community is six floors, there is no elevator, and the painting dragon carries Professor Liang on his back, Bao Chop carries a wheelchair, and the group comes down from the upper floor. Several aunts in the community saw them and lowered their voices to discuss something, Bao Chu and the captain of the criminal police were wearing police uniforms, and several aunts plucked up the courage to come over, and they reflected a situation:

There's a ghost in this building!

After the incident, the residents of the community knew about the incident, and the two policewomen were killed, and it soon spread, and in the process of spreading, people in the streets and alleys joined their imagination and speculation, and finally formed such a theory with false rumors: They were strangled to death by ghosts!

The aunts of the community swore that the building was not clean, people often cried in the middle of the night, the corridor was installed with voice-activated lights, every night at one or two o'clock, from the fifth floor to the first floor, the lights would be lit in turn, and then, from the first floor to the fifth floor, the lights were turned on one by one, and so repeated several times, however, strangely, no one went upstairs or downstairs.

The security guard in the monitoring room also confirmed this strange thing, he called up the video, because the camera is a long-range monitoring of the building, plus one or two o'clock in the night, the light is very dim, and the video screen can not see the scene of the entrance and exit, only to see the lights in the corridor turn on, go out, light up again, go out...... The windows in the hallway were low, and if someone went up or down the stairs, they would definitely be able to see it from the surveigance, however, no one walked by.

The captain of the criminal police wrote down the phone number of the duty room of the city bureau and told the security guard that if such a strange thing happened again, he would call this number, and the police would be on duty 24 hours a day.

When the special case team and the captain of the criminal police returned to the Puyuan City Public Security Bureau, the director's face was heavy, and many cadres and policemen gathered in the conference room, and the atmosphere was very serious. The director said that Xiao Sun's grandmother heard the bad news and died of a heart attack, and the girl was from the countryside, and her parents and grandmother worked hard to raise her, but she was killed......

Director Pujiang's eyes were red, and the other police officers stood up, each handwriting a document about his activities during the two days of the weekend, as well as his impressions of Sun Qiruo and Li Wanting.

Professor Leung understands that these police officers want to start with themselves first, and at the same time express a determination to solve the case as soon as possible.

Director Pujiang said that all police officers, including the director of the bureau, obey the command of the special case team, and all cases will make way for this case, and the murderer must be caught as soon as possible to comfort the souls of the deceased.

Professor Liang looked at everyone and said, "Sun Qiruo and Li Wanting are not only your colleagues, but also our colleagues in the special case team, and the police in the world are one family. ”

Next, Professor Liang made a detailed division of labor:

1. Focus on investigating the people who can enter the rooms of the two female policemen, what computer maintenance workers, food delivery, gas delivery, make a detailed list, and the criminal police captain is responsible for it. The empty room where the two policewomen lived, as well as the storage room, were also to be carpet searched, interviewing the upstairs and downstairs residents.

2. Hualong led a team of policemen to the riverside where the body was found to carefully investigate, especially underwater, and sent divers into the water to inspect it.

Third, Su Mei was responsible for checking the computers of the two policewomen to see if there was anything suspicious, and printing out the chat records and Internet browsing records.

Fourth, Bao Chop and the technical staff re-examined the physical evidence such as "underwear", "water glass", "stockings", and "hair" to extract DNA.

Director Pujiang asked, "Do you need me to do anything?" ”

Professor Liang said: "You ask the traffic police to find the homeless man, he is the first witness, maybe he can provide any clues." Also, let the pre-trial experts in your bureau re-interrogate those citizens who play mahjong, and make the transcripts more detailed. ”

Everyone took their own responsibilities and took action, and soon, all kinds of clues and news came together.

Bao Chu reported the test results to Professor Liang, and the results showed that body lotion and semen were extracted from the stockings, and then Bao Chu said something unbelievable: the cup on the table was not filled with water.

Professor Leung asked, "What's that?" ”

Bao Shu replied: "Urine." ”

After laboratory testing, the liquid in the cup was the same as the liquid extracted from the toilet. It's incomprehensible, if the killer comes back to that room at night, why would he fill the water from the toilet bowl into the cup?

The captain of the criminal police submitted a list of all the people who had been to the residence of the two female police officers in the three months prior to the incident: toilet squeewers, postmen, renovation workers, food delivery workers, broadband maintenance workers...... This time, the captain of the criminal police did not forget to put his name in the list.

Su Mei checked the credit card consumption records and bank account information of the two policemen, and found no abnormality, but felt that the savings of the two policemen could not be linked to their salaries. There is nothing suspicious in the browsing history and chat history in the computer, in a hidden folder, Su Mei found a lot of photos of the two policewomen, including headshots, photos of travel, graduation photos, which look very intimate, and a group of artistic photos: Sun Qiruo is wearing a cheongsam Fuqin, the image of a beauty in ancient costumes, and Li Wanting is wearing a floor-length skirt and is dressed as a noblewoman; Behind are several photos of revealing scales, wearing various stockings, showing off beautiful legs, and a police uniform with a gun, as well as a cold image of a whip and batons and handcuffs.

This group of artistic photos has thin codes on the face and the siren.

Professor Leung was interested in the whip in the photo, which was a leather loose whip that was not long and resembled a horse's tail. He asked forensic doctors to determine whether the bruises on the buttocks of the two deceased were the result of whipping, and asked Su Mei to continue searching for hidden information in the computer.

Soon, the whip on the photo was found, and Hualong led a team of divers to find Sun Qiruo's bag in the waters where the body was dumped, which contained a whip, handcuffs, a dog collar, and a few stones, but no mobile phone or wallet was found.

Everyone was busy until the night, Professor Liang held a press conference on the case, the deceased Sun Yanruo had a pair of leather ** underwear tied to his feet, and a stone was placed in the bag, the murderer probably wanted to tie stones to the deceased's feet and sink the body to the bottom of the river, but because the cruise ship was approaching, the murderer panicked and threw the body and bag into the water indiscriminately. The murderer is likely to have a car, or other means of transportation, and Li Wanting's body was abandoned on the street, indicating that the murderer's criminal psychological quality is not high, and he has no time to prepare carefully, and he panicked and only wants to throw away the body.

At the end of the meeting, it was more than 12 o'clock in the night, and the police on duty suddenly broke into the conference room and said: "The security guard of the Graceland community called and claimed that the building was haunted again, and the unit where the two policewomen were located, the lights from the first floor to the fifth floor were turned on in turn, but no one could be seen going upstairs." ”

The phone did not hang up, the security guard called with his own mobile phone, and the three security guards were bold enough to go to the corridor to check, Professor Liang asked them to calm down and not hang up the phone on the phone, and at the same time asked the captain of the criminal police and Hualong to drive to the Graceland community immediately.

Everyone was quiet and listening, and there were whispers of a few security guards talking and going upstairs on the phone.

The windows in the hallway were open, and the three security guards only felt the wind gusting, and one of the security guards said into the phone, "I'm scared." Professor Liang said on the phone: "The police will be there soon, so don't be afraid." The security guards didn't go upstairs, they chose to wait around the corner on the second floor, nervous one by one, looking up at the stairs. The lights on the fifth floor were on, and the security guard faintly heard footsteps from above, and after a while, the lights on the fourth floor were also on, and the lights on the fifth floor went out, and the footsteps became clearer and clearer, but the clearer and more creepy, this was clearly not the sound of human footsteps, it should be something rubbing against the ground, and the sound was made by the slow movement.

When the voice came down to the third floor, the lights on the second floor where the security guard was located went out.

They stayed in the dark, shivering, neither coughing nor stomping their feet to turn on the voice-activated lights, but looked at the stairs with great nervousness, and finally, their eyes widened, and something slowly climbed over the corner of the stairs......

The police on duty in the room couldn't see the scene, and only heard the creepy exclamation of the security guard on the phone: "Ah...... Hell. ”
