There were rumors that they caught the BTK killer due to the hidden printer dots at the church where he served, but it was actually meta data left on the floppy disc that did him in...

"They also found that the disk had been used at the Christ Lutheran Church and the Park City library."

“It’s pretty basic stuff,” Landwehr says about the reconstruction of the deleted information. “Anybody who knows anything about computers could figure it out.”

So how did the disk save the church info??

I did a few second search and it looks like he deleted a file (which is easily recoverable if the disk wasn't intentionally rewritten several times to prevent it) and it was a Microsoft Word file that had been edited by "Dennis" on a computer belonging to "Christ Lutheran Church". There are dozens of services that will recover lost data for you today on SD Cards or Hard Drives.. the FBI surely had that capability.
