why Sangwoo didn't clean blood spatter ? He always clean after his mess!
What make him confidant he woulden't be a suspect ?
I realy want more details ┗( T﹏T )┛
You are right , but the risk of being caught wasn't zero !
There are cases with teenage murderer , one I can remember is Menendez brothers who killed their parents . Allegedly because of sexual and emotional abuse during their childhood .if Sangwoo had cleaned the blood spatter, he could report his mother is missing and this wouldn't have had any risk . Or if he abandoned her body somewhere else like his father's corpse the risk of being a suspect would have been low . I think this doesn't look like Sangwoo.
Is it truly possible to close a case as a homicide without finding the corpse or murderer ?
Yes, if the amount of blood found is enough to rule out a person's death and the officer said exactly that. A person can't survive after 40% percent of their blood volume, so you find a crime scene with 2 litres of blood or more means the victim is dead. What will determine if it's a homicide or not is the evidence.
What a helpful book! He just read one patagraph and it worked!!
