http://snipurl.com/4c79j - The True Crime Report Robert Marko called himself a "cold blooded killer" on his own MySpace page, screen name Rex290. He and Judi Lawrence became acquainted via MySpace, and on Friday she vanished. Marko, a soldier at Ft. Carson in Colorado, has been arrested in connection with her murder. If he did kill Judi, some of the stuff he left behind online may prove just what a monster he truly was. Maybe even a serial killer in the making.
