Masao Koda was woken up by Xingchen's words, he suddenly got up, and was about to go to the construction site next to the villa. Pen "Fun" Pavilion www.biquge.info

"Mole Starman, calm down!" Xingchen stopped Masao Koda's reckless move, "The conclusions I just made are all my unilateral speculation, and so far, we don't have any substantial evidence. ”

"Even if there is only one percent hope, I will try!" Knowing that there will be corresponding consequences, Masao Koda is still unwilling to give up.

"I have two plans now, I don't know which one you would like to choose?" Xingchen stretched out two fingers and said: "First, we contact the construction company and ask them to approve us to enter the construction site to search, the approval procedure of this plan may be more troublesome and time-consuming, but it is better to be safe, and there will be no worries." ”

"And what about the second plan?" Masao Koda obviously didn't want to pimp with the relevant authorities, and he was anxious to find out the body of his sister Sanae and bring Mianguan to justice.

"The second way is when you sneak into the site at night to dig. As far as I know, Mianguan was watching the site during the day, but he couldn't be a sleepless 24-hour watch, so you had a whole night to dig. Xingchen suggested to Masao Koda, "Personally, I prefer to choose the first safe option. ”

In the aesthetics of the stars, it is not only necessary to win, but also to win beautifully. Not only should you be satisfied with the result, but the process should not leave a handle on people.

Masao Koda hesitated, he took out a cigarette from his pocket and lit it, and smoked it vigorously.

After a moment, he snuffed out his cigarette butt, made up his mind, and asked, "Even in one night, I can't dig the whole site." ”

Xingchen sighed slightly, it seems that the Mole Star Man still chose the riskier method, in fact, if he chooses the first method, he may not even need to dig up the corpse at the scene to find the murderer. As long as the news of the application for approval procedures is revealed to Mianguan, he will personally transfer the corpse as a thief, and it will be more convincing to get the stolen goods at that time.

"From the confession of your sister colleague, we learned that on the day of her disappearance, a colleague sent her a lot of cosmos seeds, and when my friends and I went into the construction site to play baseball games, we saw a cosmos in the flower bed, I think it is possible that when the body was buried, the seeds were accidentally scattered, so you should start digging around that place first!"

After listening to Xingchen's reasoning, Masao Koda had a little more confidence in the discovery of his sister's body.

At 12 o'clock in the middle of the night that night, Masao Koda entered the construction site from the sewer with digging tools, turned on the light of his helmet and looked around the construction site, he walked up to a cosmos, rolled up his sleeves, brandished a shovel and began to dig.

Seeing the shovel flying, the "Mole Star Man" exerted his unique talent for digging holes.

Soon, Masao Koda dug up a female corpse with a somewhat decomposed face, judging from the body and clothing of the corpse, the deceased was his sister Sanae Koda.

Holding back the grief in his heart, Masao Koda dialed the police station with trembling hands.

Five minutes later, Twilight, who had been prepared for a long time, led a group of men to the scene where the body was found.

"Judging by the degree of decomposition on the surface of the body, the time of death was about a month ago. The cause of death was a blow to the back of the head of the deceased, resulting in a rupture of the skull. A white-gloved medical examiner conducted a preliminary examination of the body at the scene: "The detailed autopsy results need to be brought back to the laboratory for autopsy. ”

"Officer Twilight, you must catch Mianguan and avenge my sister!" Masao Koda shouted with tears on his face and his hands clutching Officer Twilight tightly.

"Don't worry, we police won't let go of any bad guys!" Twilight said to him by gently patting him on the shoulder.

Later, Twilight turned to Takagi and instructed, "Arrange for someone to keep watch over Yoshiichi's villa 24 hours a day, and the others will bring the body back to the laboratory for further detailed testing." In addition, you put the case file in order and apply for a search warrant from your superiors tomorrow morning. ”

After arranging the relevant matters, there was no point in Twilight staying at the scene, so he ordered a new police officer to drive him home to catch up on sleep.

The next day, after eating breakfast, Twilight walked into the police station full of energy, and saw Takagi with panda eyes on his head, and the case file that had been sorted out on his desk.

Twilight patted Takagi on the shoulder and said earnestly, "Do a good job, I'm optimistic about you!"

Praised by the leader, Takagi immediately straightened his waist, and shouted loudly with his eyes a little moist: "Hi!"

Twilight first examines the medical examiner's overnight autopsy report, which shows that the DNA extracted from the corpse has been compared to Masao Koda, proving that the deceased is indeed his sister Sanae Koda.

Sanae Koda found no signs of poisoning on her body and had not been sexually assaulted before her death. The fatal injury was in the back of the head, and there were multiple impacts all over the body, especially the ligaments in the bare part of the foot, which showed signs of severe strain.

The medical examiner deduced that the victim was most likely killed by the killer who pushed down the stairs.

"Takagi, what do you think of this case?" After reading the case report, Twilight did not immediately dispatch police officers to arrest Yoshiichi Mianguan, but picked up a cup of tea and gently sipped it.

Takagi recalled seeing a case in the textbook of the police academy, and said, "I think that if we only need to test the blood stains around the stairs of Mianguan's villa, we can prove that the victim was killed in his house, and when the time comes, the evidence is conclusive, and he can't rely on it." ”

The bloodstain test, technically known as the luminol reaction, is used to identify blood stains that have been scrubbed and have been used for a long time. It is a kind of yellow crystal or beige powder at room temperature, which is a strong acid, which has a certain irritation effect on the eyes, skin and respiratory tract. When testing blood stains, luminol reacts with heme and exhibits blue-green fluorescence with a sensitivity of 1 in 1 million.

How could Takagi not understand the criminal investigation skills that Takagi said, for Twilight, who has been a criminal police officer for more than 20 years! However, standing in the position of a police officer, Twilight has to consider more than just arresting the real murderer.

After thinking for a moment, Twilight ordered Takagi, "Don't arrest Mianguan yet, you bring someone to invite him to the police station in the name of assisting in the investigation." Remember, be polite!"

Takagi didn't understand why Officer Twilight wanted to be polite to the suspect, but he still followed Twilight's instructions and invited Mianguan to the police station to take notes.

In the interrogation room, before the police had time to carry out psychological tactics against Mianguan, Mianguan Yoshiichi poured beans into the bamboo tube and confided in detail the details of his accidental killing of Miss Sanae and burying the body.
