The point is you said that we had been able to put both victims within .5 miles of each other, when that information actually tells us no such thing.
All that needs to happen, is for each girl to be within distance of the perp if these cases are related. More than plausible. <modsnip> I'm allowed to use what advanced statistics have taught me to form an opinion even if its the wrong one.
Here's my profile:
I think we are looking for a white male (possibly Italian), who is big/strong and can easily over power fit women with punches, who is either someone she recognized from back in NYC or someone decent looking/trustworthy enough to stop jogging for (Ted Bundy), aged 27-45 and will have some connection to these two either directly through friends, the gym, beach, club or indirectly through social media. Regarding the inconsistencies of the first and second murder, I think that he is relatively new at killing but due to the violent nature of knocking someones teeth out and then burning the second body, I think we are looking for someone with an extensive violent past via either first fights, domestic violence, assault, rape, etc.
