how you react if you saw a dead body

I smelled a dead body about 19 years ago but thought it was an dog that maybe a coyote killed in a patch of woods behind the apartments where I lived. It was a young woman’s body, she lived in the duplexes across the street and had come up missing. A few days later the police took cadaver dogs out there to search the area and couldn’t find her body. This was in August and she would have been decaying by then. I have a feeling someone may have been holding her against her will and took her there later and hung her body in a tree. A boy found her skeleton a few months later and thought it was a Halloween prank and he took the bones and piled them up behind one of the buildings. He couldn’t get the skull loose so he asked an old man if he had any bolt cutters he could borrow. The man said he thought he better find out what that boy was up to before he loaned out his bolt cutters. So he walked around and watched the boy and found the pile of bones and called the police. They interviewed the boy and asked him why he was collecting the bones and he said when his mother was gone he was going to pull back her bedspread and reassemble them in her bed and pull the covers back on top to pull a prank on her. I don’t understand why it took so long to find that body. There was a group of teens that would go out there at night and smoke dope or whatever. Did they find it and decide not to go around there any more or were they a part of it or what? Too many unresolved questions. I moved away in December so wasn’t there when it was found
