Appropo of nothing particularly technology related - other than the fact that his kiddy porn was allegedly on a computer - John Mark Karr - the guy who claimed to have killed JonBenet Ramsey - is a free man today, as the Sonoma County District Attorney dropped all charges just moments ago, a well-informed source informs SiliconValleyWatcher.

The case was pretty much of a mess since the Sheriff's Department lost the hard drive it had confiscated when they originally arrested him on child porn charges back in 2003. The DA later claimed it had hundreds of porn images on a zip drive.

"There was not enough evidence to proceed - it would be difficult to prove whether computer had the porn on it when it was in Georgia & he moved with it, having deleted it, or whether it was deleted in CA," the source said. "That and the fact that empaneling a decent (i.e., non-tainted) jury pool would be damn-near impossible."

The Santa Rosa Press Democrat was the only media attending the hearing today, so it will be fun to watch the networks scramble for the story.
