Mark's POV
I take a sip of cold coffee, my stomach churning with hunger, but I still have more important things to take care of.
From the results that the forensic lab just sent me, the probability of Selina Frank becoming a suspect has changed from 10% to 30%. To discover how the killer killed and disposed of the victim's body is still a difficult problem, but once there is a suspect, the direction of the investigation will become much clearer.
In fact, in my process of solving cases for nearly a decade, what led me to victory was not real evidence, but a detective's intuition. There are many cases that seem to have reached a dead end, but just a flash of hunch can open up a new path for me to the truth. I don't have any basis to determine how the perpetrator killed the victim in the end, but I will find it by studying the suspect's motives.
The truth is that the murder case of the criminal is more difficult to solve than the case of the murdered girls. In fact, from the evidence found next to the criminal's body, we have traced the traces of other accomplices. In addition to the fingerprints found on the weapon, there was also a two-layer encrypted radio used as a communication device between criminals in the gang. Although the sound has been distorted and the radios are integrated with a jammer, their calls are optimally secured. However, with talented technology experts and skilled electrical engineers, it won't take too long for the police force to uncover the true identities of the remaining criminals. It was only a matter of time before the serial killer case was solved.
This is also an important detail that makes me affirm that the person who killed one of the criminals must have knowledge about the case of the murder of girls, even his purpose is for the police to detect. body and quickly solve this case. As such, it is most likely that he is related to the previous victims, possibly relatives or acquaintances who want to avenge their deaths. The second possibility is that the perpetrator is the person present next to the subject of the criminals, when the criminal broke in and wanted to kill the fourth girl, he was killed by the opponent.
Except for the above two possibilities, the possibility of the perpetrator being murdered by an unknown person is very low, because no suspect has any motive to commit the murder. With all the evidence intact next to the body, it can be determined that the perpetrator is a rather self-satisfied person, he doesn't seem to worry about his identity being revealed. Or simply because he is confident that his crime is not traceable, the police cannot find out his identity.
However, with the button found under the apartment building, it became an important evidence to guide the investigation agency. Selina Frank became the most suspected object in this case. However, from my informal interrogation with her this afternoon, I assume that Selina wasn't even aware that she had been targeted by criminals. When I said that the police suspected a serial killer that had targeted her, Selina had a very normal expression of surprise and fear. Dilated pupils and sudden muscle tension are signs that are hard to fake. That's why the suspicion that Selina is the culprit becomes unreliable.
On the other hand, the victim was an adult male of standard height and weight, he was about 1.8 meters tall and weighed about eighty kilograms. With this weight, committing a crime would be impossible for a petite girl like Selina. She was only about 1.55 meters tall and weighed no more than fifty kilograms, with a light body weight and no muscles, her ability to attack an adult man was zero. Although according to the results of the forensic examination, the victim died from a severe injury when falling from a height of more than ten meters to the ground, the perpetrator may not need much strength to attack. But the fact that the victim did not show any signs of resistance or struggle before dying shows that the opponent has the ability to quickly and accurately commit the crime, can determine in terms of body and strength, he cannot be inferior to the victim. core.
At this point my suspicions turned to another object. That is the mysterious boyfriend in the story of Selina Frank. First of all, it must be a man, age and occupation are unknown, but compared to Selina, his ability to commit crimes is definitely higher. The button was found on the grass opposite the window at the apartment building where Selina lived, I can speculate that it was there while the criminal tried to break in through the window. . Tomorrow the police will return to the place again to check for possible traces.
For example, the victim's blood, hair or fingerprints. If we find convincing evidence, we can apply for a warrant to search the residence and question the suspect. In addition, the existence of the man next to Selina is still a mystery, the police need to determine his identity and find evidence against him in court if he is really the culprit.
I outlined the important details of the case. Assuming that Selina Frank is the fourth girl targeted by the criminal gang, then the crime scene may happen in her own apartment like the previous victims. The perpetrator will enter the house from the window, then use the victim's sleep to kill. However, this time the criminal had encountered a roadblock, that was the boyfriend who was suddenly present in Selina's apartment between twelve o'clock at night and one in the morning, the exact time frame that the criminal is killed. I'm assuming the criminal and Selina's boyfriend met when he broke into the house, then the possibility of a dispute is very high. However, the victim's body showed no signs of being attacked, only bruises from broken arteries and broken bones. Then the possibility of a scuffle is eliminated. This is a bit confusing because usually the homeowner's response when a stranger enters is to attack the opponent or scream to run away. These two actions will both result in an unannounced brawl. So why did the criminal and the other man not attack each other?
Also when the criminal broke in through the window, then where was he killed? In the house or outside? The police checked the windows and around the living room, although time was limited, but with our excellent professional ability, we still could not find anything unusual.
What is the problem here? Has the criminal broke into the house? Or was he killed outside? The height from the fourth floor of the apartment building to the ground is about twelve meters, if the criminal falls from this height, he can completely die as the forensic cause has given. The question is if the above assumption is correct, how did the perpetrator clean up the scene and move the corpse to the vacant lot? Also, how were the blood stains around the body with different distances and sizes created? If I can't solve these doubts, I still can't conclude anything about this case.
How? How? These tough questions still torment my brain. That gave me both a headache but also an excitement. During more than a decade of different difficult cases, I have never encountered a case with such strange circumstances. What tricks did the killer use to commit the crime? I can't wait to find the answer.
