I live right outside D.C., have worked in D.C. since '94, and this is the first I've heard of Guandeque or these attacks. I just did a google search on "Ingmar Guandeque" and "Rock Creek Park", and all that turned up were two Department of Justice documents. I don't think the press reported Guandeque and his attacks
at all before now.
Really weird, considering the obvious possibility of connection with Chandra Levy's disappearance.
I remember the media once in a while mentioning the possibility of a serial killer. But, they NEVER mentioned this guy by name, or mentioned these two cases to my knowledge.
