It was hi-jacked, it went down in that Pennsylvania field.
There were plenty of pieces of wreckage. I'm not aware if the existence of a bomb can be completely discounted but it doesn't change the scenario or the outcome.

Do you know of pictures of the crash site from that day, or where this wreckage was taken? Where did they do forensics on the plane and human remains (usually some large warehouse)?

Here's a website I found with some interesting stuff about this.
