Map of Long Island, depicting locations of murder victims

Lately, I’ve been spending a lot of time looking at the timelines and potential victims of the serial killer(s) that have been plaguing the Long Island and Manorville areas over the past few decades and I wanted to get it all down in writing and plot the locations on a map. In one of my recent posts, I promised to do this. I am a visual learner and really wanted to see everything plotted out in entirety. Please note, all locations on the map are approximate and by grouping them together here, I am not insinuating that one killer is responsible for all these murders. I am just looking for a pattern and think it is important to view all these cases as a whole for now before you can begin to group certain ones together and make assumptions.
