'I was more concerned for the person's life,' Sheriff Dale Williams said.

Bully for the cops, for a change! The guys who are supposed to protect and serve, who get such a bad rap in recent years, were trying to figure out how to pay a bill for a guy who was trying to off himself. Goddamit but that makes me feel good.

You're thinking of BTK. He sent some document or other to the police on a floppy disk (after asking THEM if there would be any way to trace it back to him). The document was written in MS-Word! They just had to pop up File->Document Properties and there was his name: Bob T. Killer (or whatever).

If it's a Word doc, you might consider going through it with a hex editor or doing an ascii dump on it, as your skills allow. New documents sometimes pick up information about the registered owner of the software, the computer, the date/time, etc. PDF files have such metadata as well.

Digital photos often contain EXIF information showing the model of camera, as well as the time and date the photo was taken. The whereabouts of the the owner of a camera of the same model listed might be quickly correlated to the time/date shown in the photos.

All this information is easily removed, but you should be careful to scrub the data itself, along with any devices used to transport it, while keeping your links to the source minimal.

Cheers!
