Not a mass shooting.

So, this is the back round, and all I know, the other day my dad told me about this.
He said there was a kid (I don't know how long ago) who shot him self, and he did it when a freight train was going through his neighbor hood, and so no one heard the gun shot. He then told me that the kid laid there for a weekend before he was found, alive.

I wanna find more on this because it is interesting. Let me know if you have heard of this and know what it is.

Thanks.
