Then whose is it.....

I drive past it every day, and one day I noticed:

Someone left their jacket near the forest, and never came back for it.

So? Whose is it? Why did he (or she) leave it there? Doesn't the owner miss it?

I've already ruled out that it belongs to murderer, who hides in the forest, and that the jacket contains a lot of blood inside.
(My fantasy tends to run a little wild)

Anyway, I guess that I will continue to wonder so for the rest of my life, or at least until it is removed...
