Hi everyone. Longtime lurker, first time poster here.
I've only lived in Boston a few years and I was a child when Karina disappeared, so I'd never heard the name Karina Holmer until I found this thread. I'm surprised that it seems to have gone cold so quickly and that we never learned much else about what happened the night she disappeared. I've seen sleuthers on here do some excellent brainstorming on other cases, so I'm hoping to spur some more discussion. Karina deserves that!
Google Maps has come a long way since this thread was started in 2005. I made a map showing all of the locations of interest that we know of.
MAP - KARINA HOLMER I used the *very* helpful timeline that insatiable posted here a few years (!) ago.
I did some sleuthing to see if I could figure out the exact location of the condominium complex in Dover, MA where Frank Rapp and Susan Nichter lived (and where Karina lived/worked as an au pair). I used an address linked to both Rapp and Nichter's names, which is in a condo complex, but it may not be where they lived in 1996. If it is, this is where the trash can fire occurred, 200 feet from the home on Monday, June 24.
I have set the permissions so that anyone with the link can edit the map, but if you have a location to add and don't feel like/know how to add it, I'll happily do so!
ETA: Karina was spotted along Boylston St. the night she disappeared, but it's not specified exactly where. However, as you can see from the map, Boylston runs directly between the club Zanzibar and the location where her torso were found.
